    Abstract: Regulation of environmental externalities like global warming from the burning of fossil fuels (e.g., coal and oil) is often done by capping both emission flows and stocks. For example, the European Union and states in the Northeastern United States have introduced caps on flows of carbon emissions while the stated goal of the Intergovernmental Panel on Climate Change (IPCC) which provides the science behind the current global climate negotiations is to stabilize the atmospheric stock of carbon. Flow regulation is often local or regional in nature, while stock regulation is global. How do these multiple pollution control efforts interact when a nonrenewable resource creates pollution? In this paper we show that local and global pollution control efforts, if uncoordinated, may exacerbate environmental externalities. For example, a stricter cap on emission flows may actually increase the global pollution stock and hasten the date when the global pollution cap is reached.

    Abstract: The U.S. Clean Air Act Amendments of 1990 initiated the first large experiment in the use of market-based regulation to control environmental problems with the introduction of an emissions trading program for sulfur dioxide emissions. Later that decade the second large trading program began for control of nitrogen oxide emissions. Although these programs are widely viewed as successful, their development and the emergence of associated environmental markets took various turns that provide lessons for the development of new markets, including markets for greenhouse gas emissions. This paper reviews the history of these programs and provides a glimpse of their future given the introduction of new regulations affecting multiple pollutants and given the expected implementation of climate policy.

    Abstract: Environmental impacts of agricultural production, such as greenhouse gas (GHG) and nitrogen emissions, are of major concern for scientists and policy makers throughout the world. Global agricultural activities account for about 60% of nitrous oxide and about 50% of methane emissions. From a global perspective, methane and nitrous oxide constitute crucial GHGs. They contribute substantially to climate change due to their high potential for effecting global warming compared to carbon dioxide. Emissions of these gases depend on the extent of agricultural production and applied technologies. Therefore, analysis of potential mitigation opportunities is challenging and requires an integrated approach in order to link agricultural economic perspectives to environmental aspects. In view of this, a mathematical programming model has been developed which enables assessment of cost-effective strategies for mitigating GHG and nitrogen emissions in the agricultural sector in Switzerland. This model is applied to improve understanding of the agricultural sector and its behavior with changing conditions in technology and policy. The presented recursive-dynamic model mimics the structure and inter- dependencies of Swiss agriculture and links that framework to core sources of GHG and nitrogen emissions. Calculated results for evaluation and application indicate that employed flexibility constraints provide a feasible approach to sufficiently validate the described model. Recursive-dynamic elements additionally enable adequate modeling of both an endogenous development of livestock dynamics and investments in buildings and machinery, also taking sunk costs into account. The presented findings reveal that the specified model approach is suitable to accurately estimate agricultural structure, GHG and nitrogen emissions within a tolerable range. The model performance can therefore be described as sufficiently robust and satisfactory. Thus, the model described here appropriately models strategies for GHG and nitrogen abatement in Swiss agriculture. The results indicate that there are limits to the ability of Swiss agriculture to contribute substantially to the mitigation of GHG and nitrogen emissions. There is only a limited level of mitigation available through technical approaches, and these approaches have high cost.

    Abstract: This paper discusses short-run and long-run effects of"green stimulus"efforts, and compares these effects with"non-green"fiscal stimuli. Green stimulus is defined here as short-run fiscal stimuli that also serve a"green"or environmental purpose in a situation of"crisis"characterized by temporary under-employment. A number of recently enacted national stimulus packages contain sizeable"green"components. The authors categorize effects according to their a) short-run employment effects, b) long-run growth effects, c) effects on carbon emissions, and d)"co-benefit"effects (on the environment, natural resources, and for other externalities). The most beneficial"green"programs in times of crisis are those that can stimulate employment in the short run, and lead to large"learning curve"effects via lower production costs in the longer term. The overall assessment is that most"green stimulus"programs that have large short-run employment and environmental effects are likely to have less significant positive effects for long-run growth, and vice versa, implying a trade-off in many cases between short-run and long-run impacts. There are also trade-offs for employment generation in that programs that yield larger (smaller) employment effects tend to lead to more employment gains for largely lower-skilled (higher-skilled) workers, so that the long-term growth effects are relatively small (large). Ultimately, the results reinforce the point that different instruments are needed for addressing different problems.

    Abstract: This paper explores two different conceptions of how an emerging climate regime might evolve to strengthen incentives for more vigorous cooperation in mitigating global climate change. One is the paradigm that has figured most prominently in negotiations to this point: the establishment of targets and timetables for countries to limit their aggregate greenhouse gas emissions. The other approach consists of a variety of loosely coordinated smaller scale agreements, each one of which addresses a different aspect of the challenge, and is enforced in its own way. The primary conclusion is that an agreement of the first type may be more cost-effective, but that a system of agreements of the second type would likely sustain more abatement overall.

    Abstract: This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE with expressions that quantify damages incurred to regional economies as a result of air pollution and lack of energy security. One of the main findings of our cost-benefit analysis is that energy security policy alone does not decrease the use of oil: global oil consumption is only delayed by several decades and oil reserves are still practically depleted before the end of the 21st century. If, on the other hand, energy security policy is integrated with optimal climate change and air pollution policy, the world’s oil reserves will not be depleted, at least not before our modeling horizon well into the 22nd century: total cumulative demand for oil then decreases by about 20%. More generally, we demonstrate that there are multiple other benefits of combining climate change, air pollution, and energy security policies and exploiting the possible synergies between them. These benefits can be large: for Europe the achievable CO2 emission abatement and oil consumption reduction levels are significantly deeper for integrated policy than when a strategy is adopted in which one of the three policies is omitted. Integrated optimal energy policy can reduce the number of premature deaths from air pollution by about 14,000 annually in Europe and over 3 million per year globally, by lowering the chronic exposure to ambient particulate matter. Only the optimal strategy combining the three types of energy policy can constrain the global average atmospheric temperature increase to a limit of 3ºC with respect to the pre-industrial level.

  8. By: Myers Madeira, Erin (Resources for the Future)
    Abstract: Much of the guidance about potential impacts of reduce emissions from deforestation and degradation (REDD) speculates how efforts would be implemented and draws lessons from other mechanisms, such as payments for ecosystem services (PES). However, with few REDD activities underway, little evidence indicates whether REDD projects are meeting these expectations. This article examines 17 REDD interventions under development in Indonesia, reports trends in project design, and assesses the extent to which interventions follow the model of pro-poor PES schemes. I find that a dominant type of REDD intervention follows a concession model and seeks to prevent large-scale conversion to plantations by outside actors. Although these projects fit the definition of PES at the scale at which the environmental service is transacted, PES characteristics are not a primary component of on-the-ground implementation. Small-holder actors are recognized as essential to the long-term success of the intervention, but are not the main focus.

    Abstract: The long-term increase in Earth's temperature is known as the global warming or the greenhouse effect. Taking into account the fact that the ice age only involved a global temperature variation of around 4 °C, it is clear climate change is arguably one of the greatest environmental threats the world is facing today. The impacts of disruptive change leading to catastrophic events such as storms, droughts, sea level rise and floods are already being felt across the world. In this context, the signing of the Kyoto Protocol in 1997 has been argued to be a historic step in reversing the inexorable increase in the emission of the greenhouse gases. The primary achievement of the Protocol has been so-called commitment of countries referred in the Annex I of the Protocol to reduce their emission of GHGs some 5% below their country specific 1990 level. On February 5, 2009, Turkish Parliament ratified an agreement to sign the Kyoto Protocol after intense pressure from both the European Union and international environmental organizations; however, so far it has not taken any step to bring about real reductions in emissions. In short, Turkey simply signed but ignored the Protocol. Present paper investigates Turkish position vis-à-vis Kyoto Protocol and critically questions Turkish policies in that area.

    Abstract: We examine the impact of a “green network effect” in a market characterized by consumers' environmental awareness and competition between firms in both environmental quality and product prices. The unique aspect of this model comes from the assumption that an increase in the number of consumers of the green product increases the satisfaction of each green consumer. We show that this externality raises the consumption of the green product, reduces the environmental quality of products and improves welfare, even if it doesn't affect the overall level of pollution. The externality correction requires using three optimal fiscal policies: an ad valorem tax on products, an emission tax, and a subsidy of the green purchase. A second-best optimum can also be reached through the green taxation.

    Abstract: The paper investigates socially optimal patterns of economic growth and environmental quality in a neoclassical growth model with endogenous technological progress. In the model, the environmental quality affects positively not only to utility but also to production. However, cleaner technologies can be used in the economy whether a part of the output is used in environmentally oriented R&D. In this framework, if the initial level of capital is low then the shadow price of a cleaner technology is low relative to the cost of developing it given by the marginal utility of consumption and it is not worth investing in R&D. Thus, there will be a first stage of growth based only on the accumulation of capital with a decreasing environmental quality until the moment that pollution is great enough to make profitable the investment in R&D. After this turning point, if the new technologies are efficient enough, the economy can evolve along a balanced growth path with an increasing environmental quality. The result is that the optimal investment pattern supports an environmental Kuznets curve.

    Abstract: This report presents results of research designed to investigate variations in willingness to pay (WTP) estimates across different scales and scopes of environmental investments. The goal is to help catchment management authorities better prioritise their natural resource management actions at both catchment and farm levels. Five split samples were used to test for scale and scope effects. A choice modelling (CM) analysis that involved the estimation of conditional logit was used to elicit household WTP for improvements in environmental quality attributes in the Namoi catchment. The approach was developed to facilitate the more accurate transfer of value estimates between different scopes of actions.

    Abstract: In a two-period overlapping generations model, this paper demonstrates that the relationship between the environmental taxation and the economic activity (level- and growth-output) becomes inverted-U shaped, when the detrimental impact of pollution on health and the private decision of each working-age agent to improve her health are taken into account. Especially, a tighter environmental tax is more likely to promote (rather than to harm) output-level and –growth when health is very sensitive to pollution, the weight of health in preferences is high, the polluting capacity of the production technology is high and the rate of natural purification of pollutants is low. The inverted-U shaped relationship between the environmental tax and the economic activity is due to a positive effect arising from the competition for resources between the final output sector and the health-enhancing activities that offsets the conventional detrimental “drag-down effect” for low values of the environmental tax. We also demonstrate that the link between the environmental tax and the lifetime welfare is inverted-U shaped as well. Finally, we investigate the social optimum and the determinants of the optimal environmental tax.

    Abstract: Diminishing emission budgets and increasing risks of catastrophic damages from climate change require analyses of rapid response options including geoengineering options such as ocean iron fertilization (OIF). To decide whether or not OIF might be such an option an assessment of its potential as an abatement option as well as its possible side effects is required. To explore the potential of OIF knowledge on the change of carbon stocks over time is needed. However, economic aspects including accounting of carbon credits need to be considered as well. In our analysis we use data from OIF modeling experiments for different years and analyze how many carbon credits would be generated and could be used for compliance. The amount of credit varies with the accounting method applied. Applying an accounting method which measures the net effect of OIF for the duration of 100 years leads to an annual carbon uptake of 0.56 to 1.69 GtC. For a shorter fertilization period, e.g. ten years the upper range increases to 2.57 GtC per year. Offsets due to other GHGs, especially N2O, as well as operational carbon emissions can be addressed by a discount factor. Considering all experiments and all accounting methods we find a maximum discount factor of 15 percent and an average value of 9 percent. From an economic as well as from an environmental perspective issuing temporary carbon credits which have to be replaced in the next commitment period seems most appropriate for short-term OIF and would provide the largest amount of credits at an early stage. This is equivalent to the existing tCER regulation under the Kyoto Protocol.

    Abstract: This paper responds to the challenge of how and when to adapt marine capture fisheries to climate change by: (1) providing a set of fisheries policy options to climate change; (2) developing a risk and vulnerability assessment and management decision-making framework for adaptation; and (3) describing the possible strategies and tactics for ex ante and ex post climate adaptation in the marine environment. Its contributions include: (1) a discussion of how management objectives and instruments influence resilience and adaptation; (2) a decision-making process to assess vulnerabilities to climate change and to manage adaptation responses; (3) an inter-temporal framework to assist decision-makers when to adapt; (4) a risk and simulation approach to confront the uncertainties of the possible losses due to climate change and the net benefits of adaptation; (5) an explanation of how adaptive co-management can promote flexible adaptation responses and also strengthen adaptation capacity; and (6) a selection of possible ‘win-win’ management actions.

    Abstract: To stay within the 2°C temperature increase target for climate change calls for ambitious emission reduction targets already for the 2012-2020 compliance period. Cost-efficiency is a crucial criterion for the enforcement of such ambitious targets, requiring analyses of all possible abatement options. Among others, enhancing the oceanic carbon sink by ocean iron fertilization (OIF) could be such an option but is currently not seriously considered due to its potentially adverse side effects. In our analysis we consider short-term large-scale OIF modeling experiments for a Post-Kyoto compliance problem to assess the economic prospects of OIF. Our analysis reveals that the critical unit costs per net ton of CO2 sequestered by OIF are in a range of 21.9 to 27.7 USD (price level 2000) assuming that the current limitations regarding the use of carbon credits generated in low cost countries and from forestation is completely relaxed. The critical unit costs are defined as those that would make an emitter indifferent between various abatement options. We are also able to show that already seven years of OIF in the area of 30° south provide the same amount of credits equivalent to a global forestation project for the duration of 20 years. Over all, our results indicate that OIF should be considered as an abatement option, but, further research, especially on adverse side effects, is needed

    Abstract: Increase in negative effects of fossil fuels on the environment has forced many countries, including Turkey, to use renewable energy sources. Today, clean, domestic and renewable energy is commonly accepted as the key for future life, not only for Turkey but also for the world. As wind energy is an alternative clean energy source compared to the fossil fuels that pollute the atmosphere, systems that convert wind energy to electricity have developed rapidly. Turkey is an energy importing country, more than half of the energy requirement has been supplied by imports. Turkey's domestic fossil fuel resources are extremely limited. In addition, Turkey's geographical location has several advantages for extensive use of wind power. In this context, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Since wind energy will be used more and more in the future, its current potential, usage, and assessment in Turkey is the focus of the present study. The paper not only presents a review of the potential and utilization of the wind power in Turkey but also provides some guidelines for policy makers.

    Abstract: This manuscript examines CO2 emissions from Vietnam's power sector using an expanded Integrated Resource Planning model. The potential effects of the following alternative policy options are examined: energy efficiency, favorably imported generation fuels, nuclear energy, renewable energy, and an internalized positive carbon value. The baseline in terms of cumulative CO2 emissions over 2010-2030 is 3.6 Gt. Lighting energy efficiency improvements offers 14% of no-regret abatement of CO2 emissions. Developing nuclear and renewable energy could help meet the challenges of the increases in electricity demand, the dependence on imported fuels for electricity generation in the context of carbon constraints applied in a developing country. When CO2 costs increase from 1 $/t to 30 $/t, building 10 GW of nuclear generation capacity implies an increase in abatement levels from 24% to 46%. Using renewable energy abates CO2 levels by between 14% and 46%. At 2 $/tCO2, the model predicts an abatement of 0.77 Gt from using wind power at prime locations as well as energy from small hydro, wood residue and wood plantations, suggesting Clean Development Mechanism opportunities. At 10 $/t CO2, the model predicts an abatement of 1.4 Gt when efficient gas plants are substituted for coal generation and when the potential for wind energy is economically developed further than in the former model.

    Abstract: We estimate Irish historical landfill quantities from 1960 -2008 and Irish methane emissions from 1968-2006. A model is constructed in which waste generation is a function of income, price of waste disposal and, household economies of scale. A transformation ratio of waste to methane is also included in the methane emissions model. Our results contrast significantly with the Irish Environmental Protection Agency's (EPA) figures due to the differences in the underlying assumptions. The EPA's waste generation and methane emission figures are larger than our estimates from the early 1990s onwards. Projections of the distance to target show that the EPA overestimates the required policy effort.

    Abstract: Three gaps in the Kyoto Protocol most badly need to be filled: the absence of emission targets extending far into the future, the absence of participation by the United States, China, and other developing countries, and the absence of reason to think that members will abide by commitments. To be politically acceptable, any new treaty that fills these gaps must, we believe, obey certain constraints regarding country-by-country economic costs. We offer a framework of formulas that assign quantitative allocations of emissions, across countries, one budget period at a time. The two-part plan: (i) China and other developing countries accept targets at BAU in the coming budget period, the same period in which the US first agrees to cuts below BAU; and (ii) all countries are asked in the future to make further cuts in accordance with a formula which sums up a Progressive Reductions Factor, a Latecomer Catch-up Factor, and a Gradual Equalization Factor. An earlier proposal for specific parameter values in the formulas – Frankel (2009), as analyzed by Bosetti, et al (2009) – achieved the environmental goal that concentrations of CO2 plateau at 500 ppm by 2100. It succeeded in obeying our political constraints, such as keeping the economic cost for every country below the thresholds of Y=1% of income in Present Discounted Value, and X=5% of income in the worst period. In pursuit of more aggressive environmental goals, we now advance the dates at which some countries are asked to begin cutting below BAU, within our framework. We also tinker with the values for the parameters in the formulas. The resulting target paths for emissions are run through the WITCH model to find their economic and environmental effects. We find that it is not possible to attain a 380 ppm CO2 goal (roughly in line with the 2°C target) without violating our political constraints. We were however, able to attain a concentration goal of 460 ppm CO2 with looser political constraints. The most important result is that we had to raise the threshold of costs above which a country drops out, to as high as Y =3.4% of income in PDV terms, or X =12 % in the worst budget period. Some may conclude from these results that the more aggressive environmental goals are not attainable in practice, and that our earlier proposal for how to attain 500 ppm CO2 is the better plan. We take no position on which environmental goal is best overall. Rather, we submit that, whatever the goal, our approach will give targets that are more practical economically and politically than approaches that have been proposed by others.

    Abstract: As the federal government weighs policy options for reducing greenhouse gases, the question arises as to how to treat imported goods from countries with less stringent emission targets. One policy option is to impose a “carbon tariff” on imported goods from those countries.

    Abstract: Using a time-separable utility function where leisure is introduced through the disutility of working time and is adjusted for quality, as measured by human capital to capture home production, we demonstrate that the environmental policy is harmful for growth. A tighter environmental tax reduces the incentives to educate by increasing leisure time and lowers the steady-state growth rate and lifetime welfare, whatever the source of pollution. We also demonstrate that the intertemporal elasticity of substitution in labor supply plays a crucial role in the marginal impact of the environmental tax on growth and welfare. When the positive influence of human capital is added into preferences (by explicitly modelling the home production sector), we find that the environmental policy promotes steady-state growth. This result challenges the finding by Hettich (1998) according to which, in the presence of leisure, the environmental tax does not affect human capital accumulation if the source of pollution is output.

    Abstract: Along with the recent success of economic growth in the developing world comes more pollution. Reducing these emissions while still enabling these countries to grow requires the use of new technologies in these countries. In most cases, these technologies are first created in high-income countries. Thus, the challenge for environmental policy is to encourage the transfer of these environmentally-friendly technologies to the developing world. This paper reviews the economic literature on both the creation and transfer of environmental technologies, with an emphasis on how the development of new technologies in leading economies can lead to environmental improvements in developing countries. I begin by discussing the incentives for environmentally-friendly innovation, which occurs primarily in developed countries. I then review the literature on the transfer of these technologies to the developing world. A key point is that technology diffusion is gradual. Early adoption of policy by developed countries leads to the development of new technologies that make it easier for developing countries to reduce pollution as well. Globalization also plays an important role in moving clean technologies to developing countries. Since clean technologies are first developed in the world’s leading economies, international trade and foreign investments provide access to these technologies. Finally, the absorptive capacity of nations is important. The technological skills of the local workforce enable a country to learn from, and build upon, technologies brought in from abroad. I conclude by discussing the implication of these lessons for policy, focusing on three examples pertaining to climate change: the Clean Development Mechanism, the role of intellectual property, and government-sponsored R&D.<BR>La croissance économique récente dans les pays en développement s’accompagne d’un accroissement de la pollution. Pour réduire ces émissions tout en se développant, ces pays devront utiliser de nouvelles technologies. Le plus souvent, ces technologies émaneront de pays développés. Ainsi, un défi des politiques environnementales est d’encourager le transfert de technologies propres vers les pays en développement. Cet article passe en revue la littérature économique sur la création et le transfert des technologies environnementales. Il met l’accent sur les liens entre le développement de ces technologies dans les pays développés et l’amélioration de la performance environnementale des pays en développement. Je commence par discuter les incitations à l’innovation favorable à l’environnement, qui se situe essentiellement dans les pays développés. Ensuite, j’analyse la littérature qui traite du transfert de ces technologies vers les pays en développement. Un résultat majeur est que la diffusion de ces technologies est graduelle. Lorsque les pays développés adoptent une politique environnementale, cela peut induire le développement de nouvelles technologies qui vont rendre plus facile la réduction des pollutions dans les pays en développement. La mondialisation joue un rôle important dans le transfert de technologies vers les pays en développement. Dans la mesure où les technologies propres émanent d’abord des pays développés, le commerce international et les investissements internationaux donnent accès à ces technologies. Enfin, la capacité d’une économie à absorber le progrès technique est un facteur important. Les compétences technologiques de la main-d’œuvre locale permettent à un pays d’apprendre et d’exploiter des technologies importées de l’étranger. En guise de conclusion, je discute les conséquences de ces résultats pour les politiques publiques, en me focalisant sur trois exemples dans le domaine de la lutte contre le changement climatique : le mécanisme de développement propre, le rôle de la propriété intellectuelle et l’aide publique à la R&D.

    Abstract: Price floors in greenhouse gas emissions trading schemes can have advantages for technological innovation, price volatility, and management of cost uncertainty, but implementation has potential pitfalls. We argue that the best mechanism for implementing a price floor is to have firms pay an extra fee or tax. This has budgetary advantages and is more compatible with international permit trading than alternative approaches that dominate the academic and policy debate. The fee approach can also be used to implement more general hybrid approaches to emissions pricing.

    Abstract: The international discussion about global climate change now revolves around what the necessary set of policies and technologies will be needed to realize reduction goals. Stabilizing atmospheric carbon dioxide (CO2) concentrations at 450 to 550 parts per million will require policy changes along with innovation and large-scale adoption of GHG-reducing technologies throughout the global energy system. Innovations will need to be supported by international cooperation and behavioral changes to further realize the benefits of technological advances. Much discussion has therefore focused on policies that target technology directly, including research and development (R&D) activities and technology-specific incentives, as well as policies and agreements that increase diffusion and adoption. This paper reviews the recent literature on trends and prospects for innovation in climate change mitigation, to identify the most important international and domestic actions necessary to technologically alter energy systems in a direction that can achieve GHG stabilization targets while also meeting other societal goals. It provides an overview of key technical issues associated with the development, diffusion, and adoption of technologies that mitigate climate change. It examines the role of environment and innovation policy measures to encourage innovation, and it outlines the conditions that trigger these advances. The review highlights that establishing a GHG emission price is essential from a technology perspective. Such a price should be coupled with public R&D support. The review discusses policy features that impact on environmentally oriented R&D, the diffusion of environmental innovations, their deployment in developing countries. In particular, the paper outlines the positive role of international technology-oriented agreements as part of the architecture of an international climate change policy.<BR>Le débat international au sujet du changement climatique porte maintenant sur les politiques et les technologies qui devront être mises en œuvre pour atteindre les objectifs de réduction des émissions. Pour stabiliser les émissions de dioxyde de carbone dans l’atmosphère entre 450 et 550 particules par million, il faut de nouvelles politiques mais aussi des innovations et l’utilisation à grande échelle, dans l’ensemble du système énergétique global, de technologies qui réduisent les gaz à effet de serre. L’innovation devra être encouragée par la coopération internationale et des changements de comportements, pour que les bénéfices des avancées technologiques se matérialisent. Aussi, une part importante du débat a porté sur les politiques qui soutiennent directement le développement technologique, notamment les activités de recherche et développement (R&D) et les incitations spécifiques, mais aussi sur les politiques et les arrangements qui encouragent la diffusion et l’utilisation des technologies. Ce document analyse la littérature récente sur les tendances récentes et à venir relatives à l’innovation pour lutter contre le changement climatique. L’objectif est d’identifier les actions prioritaires, au niveau national et international, pour changer les systèmes énergétiques d’un point de vue technologique, selon une trajectoire qui permettra d’atteindre les objectifs de stabilisation des gaz à effet de serre tout en atteignant aussi d’autres objectifs sociétaux. Le papier présente une synthèse des principales questions techniques liées au développement, à la diffusion et à l’utilisation des technologies qui contribuent à la lutte contre le changement climatique. Il analyse le rôle des politiques d’environnement et d’innovation pour soutenir l’innovation et il met en évidence les conditions qui stimulent le progrès technologique. L’analyse souligne que, d’un point de vue technologique, il est essentiel de fixer un prix pour les émissions de gaz à effet de serre. Ce prix doit être accompagné d’une politique de soutien à la R&D. Le papier présente les attributs des politiques qui ont un impact sur la R&D liée à l’environnement, sur la diffusion des innovations environnementales et leur utilisation dans les pays en développement. En particulier, le papier souligne le rôle positif des accords internationaux qui portent sur les technologies dans le cadre de l’ensemble des politiques internationales de lutte contre le changement climatique.

    Abstract: We describe the major features of a post-2012 international global climate policy architecture with three essential elements: a means to ensure that key industrialized and developing nations are involved in differentiated but meaningful ways; an emphasis on an extended time path of targets; and inclusion of flexible market-based policy instruments to keep costs down and facilitate international equity. This architecture is consistent with fundamental aspects of the science, economics, and politics of global climate change; addresses specific shortcomings of the Kyoto Protocol; and builds upon the foundation of the United Nations Framework Convention on Climate Change.

    Abstract: The regulation of greenhouse gas emissions from the electricity sector within a cap-and-trade system poses significant policy questions about how to allocate tradable emission allowances. Allocation conveys tremendous value and can have efficiency consequences. This research uses simulation modeling for the electricity sector to examine different approaches to allocation under a cap-and-trade program in California. The decision affects prices and other aspects of the electricity sector, as well as implications for the overall cost of climate policy. An important issue is the opportunity for emission reductions in California to be offset by emission increases in neighboring regions that supply electricity to the state. The amount of emission leakage (i.e. an increase in CO2 emissions outside of California as a result of the program) varies with the regulatory design of the program.

    Abstract: Economic analyses of nature must somehow define the “environmental commodities” to which values are attached. This paper articulates a set of principles to guide the choice and interpretation of nonmarket commodities. We describe how complex natural systems can be decomposed consistent with what can be called “ecological production theory.” Ecological production theory--like conventional production theory--distinguishes between biophysical inputs, process, and outputs. We argue that a systems approach to the decomposition and presentation of natural commodities can inform and possibly improve the validity of nonmarket environmental valuation studies. We raise concerns about the interpretation, usefulness, and accuracy of benefit estimates derived without reference to ecological production theory.

    Abstract: Beginning, limited-resource, and socially disadvantaged farmers make up as much as 40 percent of all U.S. farms. Some Federal conservation programs contain provisions that encourage participation by such âtargetedâ farmers and the 2008 Farm Act furthered these efforts. This report compares the natural resource characteristics, resource issues, and conservation treatment costs on farms operated by targeted farmers with those of other participants in the largest U.S. working-lands and land retirement conservation programs. Some evidence shows that targeted farmers tend to operate more environmentally sensitive land than other farmers, have different conservation priorities, and receive different levels of payments. Data limitations preclude a defi nitive analysis of whether efforts to improve participation by targeted farmers hinders or enhances the conservation programsâ ability to deliver environmental benefi ts cost effectively. But the different conservation priorities among types of farmers suggest that if a signifi- cantly larger proportion of targeted farmers participates in these programs, the programsâ economic and environmental outcomes could change.

    Abstract: Despite large uncertainties in the fertilization efficiency, natural iron fertilization studies and some of the purposeful iron enrichment studies have demonstrated that Southern Ocean iron fertilization can lead to a significant export of carbon from the sea surface to the ocean interior. From an economic perspective the potential of OIF is far from negligible in relation to other abatement options. Comparing the range of cost estimates to the range of estimates for forestation projects they are in the same order of magnitude, but OIF could provide more carbon credits even if high discount rates are used to account for potential leakage and non-permanence. However, the uncertainty about undesired adverse effects of purposeful iron fertilization on marine ecosystems and biogeochemistry has led to attempts to ban commercial and, to some extent, scientific experiments aimed at a better understanding of the processes involved, effectively precluding further consideration of this mitigation option. As regards the perspective of public international law, the pertinent agreements dealing with the protection of the marine environment indicate that OIF is to be considered as lawful if and to the extent to which it represents legitimate scientific research. In this respect, the precautionary principle can be used to balance the risks arising out of scientific OIF activities for the marine environment with the potential advantages relevant to the objectives of the climate change regime. As scientific OIF experiments involve only comparatively small negative impacts within a limited marine area, further scientific research must be permitted to explore the carbon sequestration potential of OIF in order to either reject this concept or integrate it into the flexible mechanisms contained in the Kyoto Protocol

    Abstract: In this paper we analyze the relative importance and mutual behavior of two competing base-load electricity generation options that each are capable of contributing significantly to the abatement of global CO2 emissions: nuclear energy and coal-based power production complemented with CO2 capture and storage (CCS). We also investigate how, in scenarios from an integrated assessment model that simulates the economics of a climate-constrained world, the prospects for nuclear energy would change if exogenous limitations on the spread of nuclear technology were relaxed. Using the climate change economics model WITCH we find that until 2050 the resulting growth rates of nuclear electricity generation capacity become comparable to historical rates observed during the 1980s. Given that nuclear energy continues to face serious challenges and contention, we inspect how extensive the improvements of coal-based power equipped with CCS technology would need to be if our model is to significantly scale down the construction of new nuclear power plants.

    Abstract: There is a low but uncertain probability that climate change could trigger “mega-catastrophes,” severe and at least partly irreversible adverse effects across broad regions. This paper first discusses the state of current knowledge and the defining characteristics of potential climate change mega-catastrophes. While some of these characteristics present difficulties for using standard rational choice methods to evaluate response options, there is still a need to balance the benefits and costs of different possible responses with appropriate attention to the uncertainties. To that end, we present a qualitative analysis of three options for mitigating the risk of climate mega-catastrophes—drastic abatement of greenhouse gas missions, development and implementation of geoengineering, and large-scale ex ante adaptation— against the criteria of efficacy, cost, robustness, and flexibility. We discuss the composition of a sound portfolio of initial investments in reducing the risk of climate change mega-catastrophes.

    Abstract: An ecosystem approach means different things to different people. As a result the concept of ecosystem-based fishery management is evolving and it has no universal definition or consistent application. As regards ecosystem modeling, most economic models of fishery ignore the linkages to lower trophic levels. In particular, environmental data and other bottom-up information is widely disregarded. The objective of this paper is to provide a critical review of concepts and ecological economic models relating to ecosystem-based fishery management especially to the environmental issues. The paper started by reviewing basic concepts related to ecosystem-based fishery management and the economic value of ecosystems. Then it aimed to review the development of ecosystem modeling with emphasis on economic aspects of ecology. This was followed by a presentation of the applications of ecosystem-based fishery management in practice. The paper concluded with some critical discussions and brought together conclusions derived from previous literature reviews. We found that although the concept of ecosystem-based fishery management has no universal definition, there is a widespread agreement about the need to implement the ecosystem approach for fisheries in practice. We also revealed that nutrient flow plays a crucial role in an ecosystem. In addition, it has many properties such as recycling and exchanging between consumers and producers, which are similar to monetary flows in an economy. Therefore, nutrients should be chosen as the currency in ecological economic models.

    Abstract: Large population / rapidly growing economies such as China and India have argued that in the upcoming UNFCCC negotiations in Copenhagen, any emission reduction targets they take on should be based on their intensity of emissions (emissions/$GDP) on a target date not the level of emissions. They argue that this will allow room for their continued high growth, and level commitments in the presence of sharply differential growth between OECD and non-OECD economies represent asymmetric and unacceptable arrangements. Much of the policy literature agrees with this position, also arguing that while there is equivalence between commitments if growth rates are certain, where growth rates are uncertain equivalence breaks down. However, no explicit models or experimental design are used to support this claim. Here we use a modeling framework in which countries face a business as usual (BAU) growth profile under no mitigation, and can mitigate (reduce consumption) and lower temperature change but with a utility loss. International trade enters through trade in country differentiated goods, and the impact of mitigation on country welfare depends critically on the assumed severity of climate related damage. We then consider cases where country growth rates are uncertain, and compare the impacts of levels versus intensity commitments, with the latter made equivalent in the sense that expected emissions are the same. There are different senses of this equivalence; global equivalence with differing country impacts, or strict country by country equivalence. Under intensity commitments there is more variation in both consumption and emissions than is the case with level commitments, and we show cases where level commitments are preferred to intensity commitments by all countries. Whether this is the case also depends upon how growth rate uncertainty is specified. We are also able to consider packages of mixed level and intensity commitments by country which might be the outcome of UNFCCC negotiations. Outcomes can thus be opposite to prevailing opinion, but it depends on how the equivalent targets are specified.

    Abstract: Turkey is one of the countries with significant potential in geothermal energy. It is estimated that if Turkey utilizes all of her geothermal potential, she can meet 14% of her total energy need (heat and electricity) from geothermal sources. Therefore, today geothermal energy is an attractive option in Turkey to replace fossil fuels. Besides, increase in negative effects of fossil fuels on the environment has forced many countries, including Turkey, to use renewable energy sources. Also, Turkey is an energy importing country; more than two-thirds of her energy requirement is supplied by imports. In this context, geothermal energy appears to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Since geothermal energy will be used more and more in the future, its current potential, usage, and assessment in Turkey is the focus of the present study. The paper not only presents a review of the potential and utilization of the geothermal energy in Turkey but also provides some guidelines for policy makers.

    Abstract: We apply the Parry-Small (2005) framework to asses whether the level taxation of motor fuel is broadly appropriate in a group of countries (OECD, BRICs and South Africa) accounting for more than 80 percent of world greenhouse gas (GHG) emissions. This paper deals with emissions from oil combustion in transport, which accounts for about 40 percent of CO2 emissions. In the benchmark specification, we find that six countries (accounting, in turn, for more than 40 percent of motor-fuel GHG world emissions) would be undertaxing motor fuel. We evaluate the sensitivity of the results to the values of the elasticities and externalities that we use. We find that varying the values of these parameters (within the level of uncertainty reasonably associated with them) significantly affects the results. This implies that, while informative, the results must be taken as indicative. Further analysis for a particular country must rely in a well-informed choice for the values of their country-specific parameters.

    Abstract: The recent implementation of the EU Emissions Trading Scheme (EU ETS) in January 2005 created new financial risks for emitting firms. To deal with these risks, options are traded since October 2006. Because the EU ETS is a new market, the relevant underlying model for option pricing is still a controversial issue. This article improves our understanding of this issue by characterizing the conditional and unconditional distributions of the realized volatility for the 2008 futures contract in the European Climate Exchange (ECX), which is valid during Phase II (2008-2012) of the EU ETS. The realized volatility measures from naive, kernel-based and subsampling estimators are used to obtain inferences about the distributional and dynamic properties of the ECX emissions futures volatility. The distribution of the daily realized volatility in logarithmic form is shown to be close to normal. The mixture-of-distributions hypothesis is strongly rejected, as the returns standardized using daily measures of volatility clearly departs from normality. A simplified HAR-RV model (Corsi, 2009) with only a weekly component, which reproduces long memory properties of the series, is then used to model the volatility dynamics. Finally, the predictive accuracy of the HAR-RV model is tested against GARCH specifications using one-step-ahead forecasts, which confirms the HAR-RV superior ability. Our conclusions indicate that (i) the standard Brownian motion is not an adequate tool for option pricing in the EU ETS, and (ii) a jump component should be included in the stochastic process to price options, thus providing more efficient tools for risk-management activities.

    Abstract: Environmental policy instruments that generate budget revenues may become an increasingly attractive policy option for Canada's federal government due to amplified fiscal pressures. If that is the case, revenue recycling is an essential element of pricing carbon. This paper present a brief overview of benefits of recycling carbon revenues and the challenges that may be encountered when choosing a specific option for revenue recycling. The analysis shows that the existing research leaves the open-ended question of which taxes should be used for revenue recycling unanswered; particularly in the Canadian context. Given this, the economic efficiency of different types of taxes could be used as a source of general guidance for revenue recycling. However, significant doubt exists that there is sufficient political will to recycle carbon revenue. Over the past two decades, the tax composition of the federal revenue continued shifting towards a higher reliance on economically distortive taxes instead of increasing use of more efficient taxes.

    Abstract: The Energy Independence and Security Act (EISA) of 2007 established specifi c targets for the production of biofuel in the United States. Until advanced technologies become commercially viable, meeting these targets will increase demand for traditional agricultural commodities used to produce ethanol, resulting in land-use, production, and price changes throughout the farm sector. This report summarizes the estimated effects of meeting the EISA targets for 2015 on regional agricultural production and the environment. Meeting EISA targets for ethanol production is estimated to expand U.S. cropped acreage by nearly 5 million acres by 2015, an increase of 1.6 percent over what would otherwise be expected. Much of the growth comes from corn acreage, which increases by 3.5 percent over baseline projections. Water quality and soil carbon will also be affected, in some cases by greater percentages than suggested by changes in the amount of cropped land. The economic and environmental implications of displacing a portion of corn ethanol production with ethanol produced from crop residues are also estimated.

    Abstract: This paper presents results from a model intercomparison exercise among regionalized global energy-economy models conducted in the context of the RECIPE project. The economic adjustment effects of long-term climate policy aiming at stabilization of atmospheric CO2 concentrations at 450 ppm are investigated based on the cross-comparison of the intertemporal optimization models REMIND-R and WITCH as well as the recursive dynamic computable general equilibrium model IMACLIM-R. The models applied in the project differ in several respects and the comparison exercise tracks differences in the business as usual forecasts as well as in the mitigation scenarios to conceptual differences in the model structures and assumptions. In particular, the models have different representation of the sectoral structure of the energy system. A detailed sectoral analysis conducted as part of this study reveals that the sectoral representation is a crucial determinant of the mitigation strategy and costs. While all models project that the electricity sector can be decarbonized readily, emissions abatement in the non-electric sectors, particularly transport, is much more challenging. Mitigation costs and carbon prices were found to depend strongly on the availability of low-carbon options in the non-electric sectors.

    Abstract: Increasing attention is being given to adaptation of natural and human systems to climate change. The academic literature covers a wide spectrum of perspectives. Policy considerations, on the other hand, are driven largely by techno-scientific considerations, including in particular a risk-management approach. However, the inherent uncertainties of climate change mean that conventional risk-management approaches are inappropriate because the risks cannot be quantified. Economic theory, in the form of ‘real options’, offers a conceptual alternative for specifying least-cost adaptation strategies. But little, if any, work has been undertaken to identify individuals’ preferences and priorities, a necessary precondition to estimating the benefits of adaptation measures. It is therefore proposed to identify and compare the priorities and preferences of planners, communities and individuals as a first step towards estimating individuals’ willingness to pay for adaptation measures.

This paper offers a contribution to understand these impacts on companies' strategy, by studying management systems. A typology is introduced based upon a two stage model. At stage one, the firm becomes aware of the risk and CO2 is a compliance issue. At stage two, the firm is involved in a more global re-assessment of its business portfolio including its relationship with suppliers and clients. The construction is based on three case studies: DuPont (chemicals), Lafarge (building materials) and Unilever (consumer goods). The implications of the analysis for investors are drawn.

    Abstract: Electricity trade across regions is often considered welfare enhancing. We show in this paper that this could be reconsidered if environmental externalities are taken into account. We consider two cases where trade is beneficial, before accounting for environmental damages: first, when two regions with the same technology display some demand heterogeneity; second when one region endowed with hydropower arbitrages with its "thermal" neighbor. Our results show that under reasonable demand and supply elasticities, trade comes with an additional environmental cost. This calls for integrating environmental externalities into market reforms when redesigning the electricity sector. Two North American applications illustrate our results: trade between Pennsylvania and New York, and trade between hydro-rich Quebec and New York.

    Abstract: This paper examines countries’ free-riding incentives in international environmental agreements (IEAs) when, first, the treaty is non-enforceable, and second, countries do not have complete information about other countries’ noncompliance cost. We analyze a signaling model whereby the country leading the negotiations of the international agreement can reveal its own noncompliance costs through the commitment level it signs in the IEA. Our results show that countries’ probability to join the IEA is increasing in the free-riding benefits they can obtain from other countries’ compliance, and decreasing in their own noncompliance costs. This paper shows that, when free-riding incentives are strong enough, there is no equilibrium in which all types of countries join the IEA. Despite not joining the IEA, countries invest in clean technologies. Finally, we relate our results with some common observations in international negotiations.

    Abstract: The role of economic analysis in guiding the sustainable development of estuarine and coastal ecosystems is investigated based on a comprehensive review of the literature on the valuation of the recreation, cultural and aesthetic services. The implications of the findings for the sustainable management of coral reefs, Marine Protected Areas, and Small Island Developing States are discussed. Finally, the potential of meta-analytical benefit transfer and scaling up of values at various aggregation levels is demonstrated in the context of coastal tourism and recreation in Europe. The results of the study support the conclusion that the non-material values provided by coastal and estuarine ecosystems in terms of recreational, cultural and aesthetic services represent a substantial component of human well-being.

    Abstract: This paper discusses the size of impact of carbon motivated border tax adjustments on world trade. We report numerical simulation results which suggest that impacts on welfare, trade, and emissions will likely be small. This is because proposed measures use carbon emissions in the importing country in producing goods similar to imports rather than carbon content in calculating the size of barriers. Moreover, because border adjustments involve both tariffs and export rebates, it is the differences in emissions intensity across sector rather than emissions level which matters. Where there is no difference in emissions intensities across sectors, Lerner symmetry holds for the border adjustment and no relative effects occur. In our numerical simulation analyses border tax adjustments accompany carbon emission reduction commitments made either unilaterally , or as part of a global treaty and to be applied against non signatories. We use a four-region (US, EU, China, ROW) general equilibrium structure which captures energy trade and has endogenously determined energy supply so that global emissions can change with policy changes. We calibrate our model to 2006 data and analyze the potential impacts of both EU and US carbon pricing at various levels, either along with or without carbon motivated BTAs policies on welfare, emissions, trade flows and production. Results indicate only small impacts of these measures on global emissions, trade and welfare, but the signs of effects are as expected. BTAs alleviate leakage effects as expected. In trade impacts, compared with no BTAs, BTAs reduce imports of committing countries, and increase imports by other countries. EU and US BTAs against China reduce exports by China. With BTAs, the value of production in the country with carbon reduction measures are introduced increases, and other country’s production decreases compared with the case of no BTAs. With the contraction of world trade flows caused by the financial crisis, carbon motivated BTAs offer a prospect of a compounding effect in a world which is going protectionist and decarbonized at the same time, but the added effects of BTAs seems small.

    Abstract: During economic crises, governments often increase fiscal spending to stimulate the economy. While the fiscal spending surge is sometimes temporary, recessions are opportunities to revise the spending composition often in favor of expenditures in social programs and other public goods which tend to persist over time. We model and measure the impact of fiscal spending patterns on the environment. The model predicts that a reallocation of government spending composition towards public goods reduces pollution while increasing total government spending has an ambiguous effect on pollution. We find consistent empirical results for various air and water pollutants. Increased environmental sustainability may be an important silver lining of economic crises.

    Abstract: When agricultural emissions are included in the New Zealand Emission Trading System (ETS) the economics of farming will be significantly altered. Under the legislation current in October 2009, in the early years of the system the agricultural sector as a whole would have received NZ units equivalent to 90% of 2005 emissions to ease the transition. Amendments to the Bill passed in November have delayed the start date from 2013 to 2015 and extended the protection even further. This paper addresses one of the key issues for making an agricultural emissions trading system a success: how to use the allocation of NZ units to achieve equitable and acceptable cost sharing and a smoother transition. We first discuss the potential motivations for free allocation and the two extreme potential allocation options that could be associated with the two key motivations. The option finally chosen is likely to be somewhere between these two extremes. Empirical studies can inform assessment of options. Previous empirical studies have addressed a variety of questions, including what the economic impact of the system is and on whom, how much leakage is there likely to be, and what might be the adjustment costs. We discuss each of these, comparing different existing studies and addressing some current gaps in our understanding and knowledge with new empirical work on farm level impacts and on likely responses to the ETS. We conclude by laying out some key options for allocation design and drawing links between these and the empirical material.

    Abstract: Dasgupta and Weitzman have shown that the saving rates implied by the Stern Review’s values for the rate of pure time preference and the elasticity of the marginal utility of consumption are too high from either a normative (Dasgupta) or descriptive (Weitzman) perspective. Given the attention this debate has received in the literature, there is a need for a rigorous presentation of the determinants of saving rates in models actually used to evaluate climate change policy. This paper provides the first detailed investigation of the implications of Stern’s parameter choices for saving, firstly in standard neoclassical growth theory and then in a widely used climate policy model based on that theory, Nordhaus’s Dynamic Integrated model of Climate and the Economy (DICE). In theory and practice, optimal saving rates in the presence of near-zero pure time preference are far from the near100 per cent ones obtained from simpler models used by several of the Review’s critics. We show that in DICE, for the utility function used in the Stern Review, optimal saving rates do not exceed 32 per cent, and that this falls to 26 per cent when using Stern’s revised value for the elasticity of the marginal utility of consumption.

    Abstract: For reducing greenhouse gas emissions, intensity targets are attracting interest as a flexible mechanism that would better allow for economic growth than emissions caps. For the same expected emissions, however, the economic responses to unexpected productivity shocks differ. Using a real business cycle model, we find that a cap dampens the effects of productivity shocks in the economy. An emissions tax leads to the same expected outcomes as a cap but with greater volatility. Certainty-equivalent intensity targets maintain higher levels of labor, capital, and output than other policies, with lower expected costs and no more volatility than with no policy.

    Abstract: Three recent reports have estimated the market impacts of domestic offset programs, including afforestation, contained in the American Clean Energy and Security Act (ACES). The magnitude of these estimated impacts motivates this study. We show that with carbon prices as low as $30 per metric ton, a significant number of U.S. crop acres would be used to grow trees and this would cause price increases for some U.S. commodities. Although we present only one carbon price scenario, the modeling approach that we use suggests that the acreage and price impacts we describe here would increase at higher carbon prices.

    Abstract: We analyze stability of self-enforcing climate agreements based on a data set generated by the CLIMNEG world simulation model (CWSM), version 1.2. We consider two new aspects which appear important in actual treaty-making. First, we consider a sequential coalition formation process where players can make proposals which are either accepted or countered by other proposals. Second, we analyze whether a moderator, like an international organization, even without enforcement power, can improve upon globally suboptimal outcomes through coordinating actions by making recommendations that must be Pareto-improving to all parties. We discuss the conceptual difficulties of implementing our algorithm.

    Abstract: In the last twenty years economics has created much of lasting value and real potential: it has been a very fertile period. But economics has also suffered from what I shall term „collective amnesia? covering whole areas of public policy. And on policy and the role of government it has, embarrassingly in my view, swayed with the political winds to the detriment of both our profession and to outcomes. Both the amnesia and the political bending have contributed to the economic crisis of the last year or two and to hostility towards the profession. My purpose here is first to lament the amnesia on theories of public policy in imperfect economies, in short the subject of public economics, to describe the bending of public policy analysis to political vogue, and to indicate some of the consequences. I then describe some of the mechanics of the processes described, in terms of choice of models and patterns of teaching. Finally, I use the example of climate change to illustrate some of the consequences of the amnesia, as well as of the political influence.

    Abstract: Land cover and use are critical for climate change, water quality and use, biodiversity and soil conservation as well as important drivers of rural economic activity and the evolution of rural communities. The Land Use in Rural New Zealand (LURNZ) model is a simulation model that predicts overall shifts in land use at a national scale and then allocates those changes spatially. We create a new dataset that allows us to consider fine scale land cover and use on private rural land and land characteristics associated with those land covers and uses. Second, we produce some summary statistics on the land cover transitions that were observed from 1996 to 2002. We find some evidence that supports our simple model of the relationship between land use changes and observable land quality, and the use of Land Use Capability and slope in rules to simulate the location of changes in land use and cover and also identify some directions for future work.

    Abstract: The introduction of a price on carbon dioxide will have important effects on the U.S. economy, and especially important effects on the electricity sector, which currently accounts for about 40 percent of carbon dioxide emissions. This paper examines alternative approaches to the distribution of allowance value to the sector, including free allocation to consumers through electricity and natural gas local distribution companies (LDCs). Recent proposals in the U.S. Congress, including H.R. 2454, have suggested this option as a way to address impacts on consumers and potential regional inequities. We compare allocation to electricity LDCs with a system in which allowances are auctioned and revenues returned to households as a per capita dividend. We evaluate the outcomes under alternative assumptions about how LDCs, which are regulated entities, pass through the allowance value to final residential, commercial, and industrial customers. Our results show that the LDC approach raises the price of allowances and imposes greater costs on households than the per capita dividend option. We also evaluate a more complete characterization of H.R. 2454 and show that an incremental reform to that bill would greatly reduce costs and have more balanced impacts across households in different income groups and regions.

    Abstract: Developing an allocation scheme for distributing rights amongst fishing nations is a key issue in the development of stable cooperative arrangements to exploit international fish resources. Allocation within regional fisheries management organisations (RFMOs) is generally based on the historical catches of parties to the RFMOs. However, as membership of RFMOs increases and pressure to allow additional countries, particularly coastal developing countries, to participate meaningfully in international fisheries intensifies, there is increasing policy attention being paid to the issue of allocation of rights in RFMOs. This paper explores issues relating to the process of allocating participatory rights in RFMOs, especially in those cases in which one or more fisheries remain unallocated, and is intended to stimulate discussion among policy makers on possible policy directions in such situations without directly or indirectly evaluating existing allocation schemes. The paper reviews the international legal framework governing international fisheries, the economic issues underlying allocations, and the current state of play in the allocation regimes in RFMOs. A broader perspective on the allocation issue is provided by examining the experiences of other resource sectors that have wrestled policy challenges similar to those confronting international fisheries in allocating participatory rights amongst current and potential participants - water resources; and greenhouse gases – to see if they offer any transferable insights on the issue.

    Abstract: This article examines the effect of governance on forest cover in developing countries. We develop a theoretical model that explains how governance, particularly corruption control and politically stability, affects deforestation due to agricultural land expansion. The theoretical model shows the importance of the complementarity or substitutability of technology and land use in determining the effect of governance on agricultural land expansion and, consequently, forest cover. We complement the theoretical model with a structural empirical analysis to measure the effect of corruption control and political stability on deforestation in developing countries through two direct channels of deforestation: agricultural land expansion and road building. We find that political stability has a positive and significant effect on forest cover but corruption control has a negative and significant effect on forest cover due to increased agricultural land expansion.

    Abstract: Bolivia tiene un nivel de biodiversidad extremadamente alto y pocos países del mundo tienen mayor diversidad de ecosistemas que Bolivia, cuyas características geográficas varían en altura (entre 200 y 6000 m.s.n.m), precipitación (entre 200 y 5000 mm/año), temperaturas (glacial hasta tropical) y topografía, y por lo tanto en tipos de vegetación. Los principales tipos de ecosistemas son representados en 22 diferentes áreas protegidas (APs) nacionales, y además existen numerosas APs departamentales o locales. Juntas, las APs cubren alrededor de 16% del territorio nacional. Sin embargo, esta diversidad se encuentra amenazada por el cambio climático y por la expansión de la frontera agrícola. En esto estudio se ha modelado la relación entre factores climáticos (temperatura promedio, precipitación promedio, variabilidad de temperaturas, variabilidad de precipitación) y nivel de biodiversidad, y se ha usado el modelo estimado para simular los efectos del cambio climático previsto por el modelo PRECIS hasta 2100. La modelación se ha hecho a nivel municipal para poder tomar en cuenta la gran heterogeneidad geográfica de Bolivia. El estudio también toma en cuenta que se espera un fuerte proceso de deforestación, cuyos efectos son mucho más dramáticos e inmediatos que los lentos procesos de cambio climático. Los resultados muestran que los cambios climáticos previstos por el modelo PRECIS hasta el año 2100 podrían tener impactos muy fuertes para la biodiversidad en Bolivia. Especialmente en el Altiplano, donde se prevé un acelerado proceso de desertificación debido a la reducción de precipitación y el aumento en variabilidad de temperaturas sugeridas por el modelo PRECIS. En las tierras bajas, el cambio climático no es la mayor amenaza para la biodiversidad, sino el avance de la frontera agrícola. En el escenario base (sin cambio climático) se puede prever la deforestación de 33 millones de hectáreas durante el siglo XXI, lo que deja solamente una cuarta parte del bosque original. En las áreas secas del Chaco y de la Chiquitanía en el departamento de Santa Cruz, los modelos indican un aumento en la precipitación, lo que podría tener un efecto positivo sobre la biodiversidad, si no se convierten las áreas a campos agropecuarios primero. En total, entre los procesos de deforestación y cambio climático, el nivel promedio de biodiversidad en cada lugar, se reduciría a solamente 40% del nivel original, de acuerdo con las estimaciones realizadas. Esto no significa que el 60% de las especies se extingan, ya que muchas especies probablemente sobrevivirán en áreas protegidas, pero significa que, en promedio, habrá sustancialmente menos diversidad de especies en un área dada. A nivel nacional, los procesos de deforestación son responsables del 95% de la reducción en el nivel de biodiversidad, mientras que el cambio climático solamente es responsable de 5%. Sin embargo, en las tierras altas, donde no hay deforestación significativa, el cambio climático sería responsable del 100% de las fuertes reducciones en biodiversidad previstas. Mientras que la gran biodiversidad y las ecosistemas únicas de Bolivia tienen un valor de existencia incuantificable, la biodiversidad también brindan beneficios tangibles a los comunidades locales, y estos beneficios sí se puede cuantificar, aunque de manera cruda. Por ejemplo, en muchas áreas rurales, la caza y pesca contribuye de manera importante al consumo de alimentos, y la población usa la vegetación local para materiales de construcción, medicina, alimentos, ceremonias, etcétera. La biodiversidad también juega un rol importante en las actividades agropecuarias proporcionando áreas naturales para pastoreo y servicios de polinización, control natural de pestes y variación genética en los cultivos. Además, la biodiversidad puede ser importante para actividades económicas, como ecoturismo, recolección de castañas y otros. Finalmente, la biodiversidad brinda servicios ambientales importantes, como regulación del suministro de agua, control de erosión, revitalización de suelos, y otros, que puede tener un efecto indirecto sobre el nivel de ingresos y consumo de los habitantes. Se demuestra una relación positiva entre el nivel de biodiversidad y el nivel de ingreso/consumo a nivel municipal, y se usa esta relación para estimar las pérdidas económicas que las poblaciones locales sufrirían por la reducción en biodiversidad atribuible al cambio climático (excluyendo las reducciones atribuibles a deforestación). Los cálculos indican pérdidas en el orden de 1.6% del PIB el año 2100 a nivel nacional, pero hasta 6% en el departamento de Potosí. Santa Cruz es el único departamento que podría verse beneficiado por un aumento en biodiversidad atribuible al cambio climático (el modelo PRECIS prevé más precipitación en las áreas secas de Santa Cruz), pero solamente en el orden de 0.2% del PIB. Aunque los costos del impacto del cambio climático sobre la biodiversidad son sustanciales, son de segundo orden en comparación con el impacto directo de la deforestación. Por eso, si el objetivo es conservar la biodiversidad - y los beneficios que esta brinda a Bolivia y el mundo - sería esencial implementar políticas para frenar la deforestación excesiva. La recomendación sería, entonces, apostar al mecanismo REDD, que tiene como objetivo transferir fondos de países ricos a países pobres, para ayudar a los últimos controlar los procesos de deforestación.

    Abstract: Bolivia es un país heterogéneo en todos los aspectos, incluyendo los aspectos climáticos, geográficos, culturales y económicos. Esto significa que los impactos del cambio climático también serán muy heterogéneos, brindando beneficios a unos y perjudicando a otros. Para poder captar toda esta heterogeneidad, el presente documento trabaja a nivel municipal, ya que dentro de cada municipio, las condiciones son mucho más homogéneas. El cambio climático afecta el sector agropecuario por cuatro vías principales: 1) Por cambios en temperatura, 2) por cambios en precipitación, 3) por cambios en la concentración de CO2 en el aire, y 4) por eventos extremos. El impacto de cada uno de estos efectos varía entre municipios. El modelo climático PRECIS prevé aumentos en temperaturas de 3.4 - 5.1ºC en el escenario A2 y de 2.4 - 3.7ºC en el escenario B2, con mayores aumentos en el norte del país y en el Altiplano. El impacto de estos aumentos dependerá del punto de partida, ya que los lugares actualmente fríos (el Altiplano) se beneficiarían por mayores temperaturas, mientras que áreas actualmente calientes (las tierras bajas) se verían perjudicados por temperaturas aún más altas. Los impactos de los cambios en precipitación generalmente son mayores que los impactos de cambios en temperatura, parcialmente porque los rendimientos agropecuarios son más sensibles a variaciones en precipitación, y parcialmente porque los cambios en precipitación previstos por el modelo PRECIS son mucho más grandes que los cambios en temperatura. Para el escenario A2, el modelo prevé un leve aumento en precipitación a nivel nacional (+4%), pero con enormes diferencias entre municipios (entre -50% y +51%). Para el escenario B2, el modelo prevé una leve disminución a nivel nacional (-1%), pero también con enormes diferencias entre municipios (entre -51% y +43%). En general, las áreas más secas se volverán aún más secas y las áreas más húmedas recibirán aún más precipitación, pero con excepciones importantes, sobre todo en Oruro y Santa Cruz donde se prevé aumentos en precipitación en áreas ahora relativamente secas. Dado que los niveles de precipitación tienden a volverse más extremos, esto causaría daños a las actividades agropecuarias en la mayoría de municipios (excepto en Oruro y Santa Cruz). La fertilización de CO2 tendría un efecto positivo en todas las áreas, pero más para cultivos C3, como soya, y menos para cultivos C4, como maíz. Para 2100 se espera aumentos en rendimientos por fertilización de CO2 de 20-27% en el escenario A2 y de 12-18% en el escenario B2. Estos aumentos son suficientes para convertir las pérdidas por cambios en temperatura y precipitación a ganancias totales en la gran mayoridad de municipios. Las excepciones son los municipios de Beni y Pando, donde el efecto negativo de los grandes aumentos en temperatura predominan, y en Chuquisaca, donde las grandes reducciones en precipitación predominan. Finalmente incluimos el efecto adverso de eventos extremos (sobre todo precipitaciones fuertes) cuya frecuencia aumentará sustancialmente de acuerdo al modelo PRECIS. En total, a nivel nacional, estos 4 componentes del cambio climático tendrían un efecto positivo sobre los ingresos rurales en 2100 de 4,8% en el escenario A2 y 1,5% en el escenario B2. El departamento que más se beneficiaría del cambio climático es Oruro, que se volvería menos frío y menos árido que ahora. En cambio, el departamento que más perdería sería Beni, que se volvería aún más caliente, más húmedo y con mayores perdidas como consecuencia de más inundaciones. Al nivel nacional, estos impactos corresponden a un efecto positivo del cambio climático en 2100 sobre el sector agropecuario de 0,51% y 0,15% del PIB, respectivamente. Estos porcentajes aumentarían casi linealmente desde 0% en 2000. Sin embargo, hay que interpretar estos datos con mucha precaución. Lo que más determinan los resultados son los cambios en precipitación previstos por el modelo PRECIS, y ellos tienen bastante incertidumbre.
