Abstract: | We decompose the impact of trade reform on technology adoption and land use to study how aggregate changes were driven by reallocation versus within-farm adaptation. Using detailed census data covering over 30,000 farms in Alberta, Saskatchewan and Manitoba, Canada we find a range of new results. We find that the reform-induced shift from producing low-value to high-value crops for export, the adoption of new seeding technologies and reduction in summerfallow observed at the aggregate level between 1991 and 2001 were driven mainly by the within-farm effect. In the longer run, however, reallocation of land from shrinking and exiting farms to growing and new farms explains more than half of the aggregate changes in technology adoption and land use between 1991 and 2011. |

Abstract: | Strategies to tackle deforestation are evolving. Under pressure from environmental NGOs and consumers, the major food companies are voluntarily committing to apply the “zero deforestation” principle, especially for their production of the key agricultural commodities (palm oil, cocoa, soy, etc.), which are responsible for around 70% of deforestation throughout the world. This concept is nevertheless ambiguous and difficult to implement. Payments for environmental services (PES) can help to achieve these ambitions. PES geared towards individual investment would be proposed to producers to enable them to modify their practices; these would be financed by zero deforestation companies. In addition, collective PES for forest conservation at the local level would be proposed to communities; these would be partly financed by a broad-based, low-level fee. |
Abstract: | Les stratégies de lutte contre la déforestation évoluent. Sous la pression d'ONG environnementales et de consommateurs, des grandes entreprises agroalimentaires s'engagent volontairement à appliquer le principe « zéro déforestation », notamment pour leur production de grandes commodités agricoles (huile de palme, cacao, soja…), responsable d'environ 70 % de la déforestation mondiale. Le concept est toutefois ambigu et sa mise en oeuvre difficile. Les paiements pour services environnementaux (PSE) peuvent contribuer à rendre ces filières effectives. Des PSE tournés vers l'investissement individuel seraient proposés aux producteurs pour les aider à modifier leurs pratiques ; ils seraient financés par les entreprises zéro déforestation. En complément, des PSE collectifs rémunérant la conservation des forêts à l'échelle locale seraient proposés aux communautés ; ils seraient financés en partie par une redevance à assiette large et à faible taux. |

Abstract: | There is a general agreement that agricultural growth in developing countries is needed in order to increase income and guarantee food security. Many authors agree that to achieve these goals, an increase in agricultural yield and production is necessary. However, the literature has shown a diverging discussion about which policy governments should apply for pro-poor agricultural growth. While some authors state that input subsidy policies (ISPs) are the principal tool to increase agricultural productivity for smallholders, many others say that these policies are highly costly and have not yet improved the development of rural areas. This article aims to show, from a theoretical perspective, that input subsidy policies can impact economic growth and food security. The method explores the welfare effects of a fertilizer subsidy policy on producers, consumers, government and society as a whole. The paper also examines, based on empirical data, the outcomes of the well-known Malawi farm input subsidy program (FISP). The results indicate that, as expected from theory, the FISP has raised productivity, households ’income and rural wages. However, it has not improved access to food at national level. The high cost and targeting inefficiency are also a constraint for maintaining the input subsidy program. |

Abstract: | South Africa is one of only a handful of countries in which the prevalence of child stunting has increased over the period during which progress towards the Millennium Development Goals (MDGs) has been monitored. One explanation for this reversal is that Big Food retail chains have been contributing to a low quality diet across the country, particularly in poor urban households. To examine this claim, we use nationally representative longitudinal data (2008–2014) to trace 6 years of stunting's evolution among South African children and adolescents aged 0–19, with particular attention to how the prevalence of stunting differs between urban (14.9%) and rural (19.6%) areas and how the drivers of poor nutrition vary spatially. The results suggest that, conditional on household income, subsistence farming is associated with a lower probability of stunting. Even more important, although under-nutrition retains a strong spatial component, once observable differences in living standards are controlled for, the higher tendency for children in deep rural households to suffer from (severe) stunting reverses. |

Abstract: | This paper estimates the impact of climate change on the fisheries and aquaculture sector of Bangladesh by employing appropriate econometric models. The Household Income and Expenditure Survey 2010 (HIES,2010) data have been used to estimate the Ordinary Least Square (OLS) regressions for examining the impact. Since “climate change” is a long run phenomenon, its impacts may not be discernable in the short run, cross sections data. Our econometric results find some negative impacts of climate change on the household fisheries production,though estimated coefficients are not statistically significant.Climate change therefore does not have any impact on the fisheries and aquaculture sector at the household level at least in the short run. Within HIES 2010 data, regarding geographical locations, respondent households associated with fisheries from Dhaka and Rangpur divisions (and also to a lesser extent, Khulna) have been found to be disproportionately more vulnerable to climate change-related shocks as well as having lower yearly mean household incomes, compared to their counterparts in other divisions. |

Abstract: | Several recent contributions to the literature have suggested that the strength of family ties is related to various economic and social outcomes. For example, Alesina and Giuliano (2014) highlight that the strength of family ties is strongly correlated with lower GDP and lower quality of institutions. However, the forces shaping family ties remain relatively unexplored in the literature. This paper proposes and tests the hypothesis that the agricultural legacy of a country matters for shaping the strength of its family ties. Using data from the World Values Survey and the European Values Study, the results show that societies with a legacy in cultivating wheat tend to have weaker family ties. Analysis at the sub-national level (US data) and the country level corroborate these ?ndings. The estimations allow for alternative hypotheses which propose that pathogen stress and climatic variation can potentially also give rise to the formation of family ties. The results suggest that the suitability of land for wheat production is the most influential factor in explaining the variation in the strength of family ties across societies and countries. |

Abstract: | "Objective – In this study, the impact of earthquake/tsunami threat on land prices is measured using the Hedonic Price Method (HPM). The location of the research is in Padang, West Sumatra. The subject of study is land owners who purchased their land later than September 30, 2009. Methodology/Technique – The linear model and Double-log model with Ordinary Least Square (OLS) are used to estimate variable. Findings – The findings reveal that the Linear model have five variables with a significant effect. Those variables are: (1) Environmental quality, (2) Distance to the seafront, (3) Distance to educational facilities, (4) Availability of clean water and (5) Position of the land, whereas the double-log model also have 5 variables: (1) Distance to the seafront, (2) Distance to educational facilities, (3) Access to evacuation routes, (4) Availability of clean water and (5) Position of the land. Novelty – The possibility of earthquake and tsunami threat in the future has raised a new parameter associated with the environment in the city of Padang, namely land distance towards the seafront. The findings of the study contribute the understanding in land pricing." |

Abstract: | Environmental noise - linked to traffic, industrial activities, wind farms, etc. - is a matter of increasing concern as its association with sleep deprivation and a variety of health conditions has been studied in more detail. The framework used for noise assessments assumes that there is a basic level of background noise, which will often vary with time of day and spatially across monitoring locations, plus additional noise components from random sources such as vehicles, machinery or wind affecting trees. The question that has to be investigated is whether, and by how much, the noise at each location will be increased by the addition of one or more new sources of noise such as a road, a factory or a wind farm. The paper adopts a mixtures specification to identify heterogeneity in the sources and levels of background noise. In particular, it is important to distinguish between sources of background noise that may be associated with covariates of noise from a new source and other sources that are independent of these covariates. A further consideration is that noise levels are not additive, though sound pressures are. The analysis uses an extended version of Partha Deb’s Stata command (fmm) for estimating finite mixture models. The extended command allows for the imposition of restrictions such as that not all components are affected by the covariates or that the probabilities that particular components are observed depend upon exogenous factors. These extensions allow for a richer specification of the determinants of observed noise levels. The extended command is supplemented by post-estimation commands which use Monte Carlo methods to estimate how a new source will affect the noise exposure at different locations and how outcomes may be affected by noise control measures. The goal is to produce results that can be understood by decision-makers with little or no statistical background. |

Abstract: | "Objective – This research aims to develop a policy framework to support household-based snack food industry in the East Sumba regency for poverty alleviation. Methodology/Technique – A qualitative method is applied to enable exploration. A benchmarking analysis with the snack food industry in Garut, West Java, also is conducted to gain insights of the success factors and challenges faced by the industry there. Findings – Most informants say that the East Sumba regency has a high production of food crops and fruit; thus, it has potential to develop a household-based food industry to improve the local economy, i.e., a food and snacks industry based on raw materials such as maize, cassava, sweet potatoes, peanuts, and bananas. The regency also has a long coastline; therefore, coconut, fish, and seaweed-based food industries also are a potential for development in the area. Novelty – This study findings propose a policy framework for poverty alleviation through the creation of new entrepreneurs producing local snack foods. The creation of new entrepreneurs will increase employment and it should be done by the local government by implementing policies that develop the management skills of people in four functional management aspects, which must be supported by specific policies in community leadership, community culture and mindset, public–private partnerships, government support, and infrastructures." |

Abstract: | This paper attempts to establish if climate acts as the determinant of destination choice in case of rural-to-rural migration. In the context of climate change where the link between climate and rural income has been well established, it is argued that migrants who move within rural areas choose destinations with more favourable climate conditions allowing for higher incomes. Employing the alternative-specific conditional logit model, this paper shows that such indirect effect of climate on migration destination choice is non-negligible, since one per cent increase in the expected income differentials between origin and destination, attributable to climate, increases the probability of choosing a given destination by at least nine percentage points. On the other hand, distance acts as a constraint for migration, in particular for the poorest individuals who might be inhibited from reaping full benefits of mobility |

Abstract: | The current policy of minimum price prevailing in the country should be abandoned as although this policy encourages the farmers to produce greater amounts of wheat but it is unfavorable for the government. Instead of minimum price policy, input costs need to be reduced to compete in the international markets as higher domestic prices leave a country internationally uncompetitive and increase the costs to the economy. The objective of this study was to find suitable price policy reforms. Extensive analysis revealed that higher cost of production is the main reason for higher domestic prices. Therefore, the study proposes that controlling and reducing input costs will benefit the farmers as well as the economy. Subsidies on inputs, especially fertilizers, should be given by the government as this will reduce the cost of production significantly. Moreover, reduced input cost for wheat will be the appropriate policy intervention which will lead to achieve international competitiveness. Thus, the policy recommendation on the basis of the analysis carried out in the previous sections is that subsidy should be given on inputs of wheat, especially fertilizers, to reduce the cost of production, as reduction in the production cost will proportionately reduce the support price. |

Abstract: | This paper examines the linkages between Boko Haram activities in northeastern Nigeria and declined activities in regional agricultural markets. Building on data from both the Armed Conflict Location and Event Data Project (ACLED) and the Famine Early Warning Systems Network (FEWS NET), the paper first considers the geographic distribution of Boko Haram events with respect to market towns and discusses whether there is evidence of Boko Haram activities near markets having influence on declined market operations. Next, it examines the temporal character of market operations and the timing of their changes in their operational status, including market closures, with respect to the seasonality of agricultural production and land use in northeastern Nigeria. The paper measures the frequency of changes in regional market activities and considers spatial relationships and temporal correlations with Boko Haram activities in the region over twelve periods from late 2014 through the end of 2016. Finally, the paper formulates policy recommendations for assessing and mitigating coupled challenges of human and environmental security. |

Abstract: | Abstract: In the past decades, groundwater over-exploitation has increased the vulnerability of users, social inequalities and environmental degradation. In this context, the DIALAQ project aimed to experiment and disseminate a participatory approach intended to strengthen stakeholders’ capacity to implement more sustainable agricultural and groundwater management. DIALAQ’s network encompasses 8 regions in 4 countries (India, Morocco, France and the United States) including groups of farmers, administration’s representatives, NGOs, elected representatives and researchers from several disciplines. A seed funding enabled cooperation between academics and non-academic partners that led to the consolidation of the network and enabled the design of the project. Firstly, a focused review of literature on participatory foresight exercises in the field of groundwater management is presented. Secondly, the challenges and pathways taken in designing the research is described. This process resulted in a common methodological and ethical framework presented in conclusion. |

Abstract: | This paper analyses how the premium customers pay for Fairtrade-labelled coffee is distributed in the Swedish market, using information on costs of production and scanner data on almost all roasted and ground coffee products sold by retailers. A key finding is that roasters and retailers get 43–70%, while producer countries, in this paper comprising coffee farmers, cooperatives, middlemen, exporters and Fairtrade International, get 24–51%. Fairtrade Sweden gets 5–8%. These values are upper and lower bounds that reflect assumptions made about the additional costs of producing roasted and ground Fairtrade coffee, given the cost of beans and the Fairtrade license, and whether conventional coffee is compared with organic or non-organic Fairtrade coffees. Since roasters’ and retailers’ margins are higher for Fairtrade than conventional coffee, there is evidence that Fairtrade retail prices are higher than the level attributable to costs. However, producer countries receive a significantly larger share of the premium paid than reported in earlier studies, which are either dated or analyse very small samples of coffees. |

Abstract: | This study focused on developing forecasting model for perishable commodities and tomato is taken as a case to study. The model is developed on in-depth analysis of market dynamics and structure. An estimable theoretically founded model is the major output of this study which is based on true structure of the market. Complete model is comprised of inverted demand equation, Plantation and yield equations and the role of price expectations. The study reveals the fact that the farmers’ production decisions are affected by the expected profitability which is based on the expected output prices. However, due to the involvement of certain intermediaries the farmers couldn’t get the proper prices of its output whereas the domestic production meets 31.5% to its total demand only and the deficit is imported from other provinces of the country and from India. Low per acre yield and inefficient management practices, non-availability of hybrid seed, weather conditions and less profit margins and declining area of production causes the production to fall short of its potential maximum. Moreover, the increased reliance on imports and the increased demand due to increase in population causes the domestic prices to becomes more volatile. The majority of the small farmers sell their product through commission agents and wholesaler that cause imperfections in the market. Tomatoes value chain have certain problems like there exists a disparity between the small and large farmers in cost of production, yield and profitability. The model may forecast the prices on monthly or weekly basis depending upon the data availability. |

Abstract: | The recent five years have seen a nearly tenfold increase the salmon stock price index at the Oslo Stock Exchange. This paper tries to shed some light on the reasons why this substantial stock price appreciation has occurred. The primary aim is to ascertain if the market valuation of salmon farming companies can be explained by rational factors, or there is an element of irrational exuberance behind current all-time high salmon stock prices. In particular, we examine the impact of both fundamental and operational value drivers. The results suggest that a structural shift has occurred, leading to a stronger association between fundamentals and market valuations after 2012, suggesting that at least some of the stock price increase is linked to fundamental factors. |
