| Abstract: | Climate change poses unprecedented challenges to the world’s food systems. Rising temperatures, changing rainfall patterns, and more frequent extreme weather events threaten agricultural production and the biodiversity and ecosystem services that underpin agriculture. Within food systems, climate change affects processing, storage, transport, and retailing of food and affects our food environments. These growing climate risks impact food security, nutrition, and human health, as well as equity and livelihoods, with poor food producers and consumers hit hardest. They make food systems a riskier source of income and reduce the availability of food — worsening poverty and inequity, disrupting livelihoods, and contributing to hunger and malnutrition. At the same time, food systems are failing to provide healthy diets for all, and are generating one-third of human-caused greenhouse gases. Solutions must address this complex nexus of problems. Climate change adaptation and resilience-building efforts for food systems must be accelerated to reverse growing malnutrition, ensure that all people can access healthy diets, and provide sustainable livelihoods. At the same time, efforts to transform food systems work to reduce their environmental footprint. Farmers and small businesses along food value chains in low- and middle-income countries will have to adapt their practices to a climate marked by extreme weather events and changing seasonal patterns in order to meet growing and changing food demand, while also contributing to mitigation. Support for this critical transformation requires not only the development, dissemination, and adoption of appropriate low-emissions, climate-smart technologies and practices, but also a focus on the policies, institutions, governance, and behavior change that can promote sustainable, inclusive food systems. |

| Abstract: | The U.S. Department of Agriculture, Economic Research Service (ERS) maintains and uses a dynamic dairy sector model for the United States. This model is a tool for the development of 10-year dairy projections, as published in the USDA Agricultural Projections annual report. The model is also used to analyze changes in market conditions and the impacts of changes in various Federal Government policies on the dairy sector. This report provides documentation on the specification and estimation employed by this model to obtain projections for the dairy sector. |

| Abstract: | This is the 2022 edition of the annual series documenting developments in U.S. agricultural policies, with a focus on policies related to production agriculture, agrofood value chains, and food and nutrition assistance. Developments related to production agriculture include temporary assistance programs in response to extreme weather and the continuing effects of the Coronavirus (COVID-19) pandemic; changes to standing farm programs, including commodity programs, conservation programs, credit programs, and crop insurance; the development of new programs, including the Partnerships for Climate-Smart Commodities, and the allocation of additional resources for existing USDA conservation programs to support the adoption of certain practices with climate mitigation benefits; the introduction of new measures and programs focused on improving equity; updates to USDA organic regulations and the launch of new programs to support producers transitioning to organic operations; and developments in certain laws and regulations overseen by agencies other than USDA that affect the agricultural sector. In 2022, developments in agrofood value chain policies related to the continued economic impacts of the COVID-19 pandemic and supply chain vulnerabilities. In the realm of food and nutrition assistance, 2022 saw the continued development of temporary changes to existing food assistance programs in response to the COVID-19 pandemic; the establishment of a new permanent Summer Electronic Benefit Transfer program; the implementation of various emergency actions to respond to reduced infant formula availability; and the release of a National Strategy on Hunger, Nutrition, and Health in conjunction with the White House Conference on Hunger, Nutrition, and Health. |

| Abstract: | Climate change is not projected to materially alter Malawi’s climate profile. Instead, it is likely to exacerbate existing climate vulnerabilities by increasing the frequency and intensity of cyclones, floods, and droughts. This is largely due to increased uncertainty around future precipitation levels. These adverse effects have already started to materialize and are expected to increase substantially over the next decades, particularly if efforts to reduce global greenhouse gas emissions by high emitting countries are insufficient. Climate change is also projected to increase average annual temperatures across the country. Climate change is expected to significantly affect Malawi’s economy, mainly because of its dependence on climate-sensitive economic sectors and its low capacity to take adaptation measures due to preexisting macroeconomic vulnerabilities. Malawi’s sensitivity to climate shocks is underpinned by significant environmental degradation, in particular deforestation, watershed degradation, and poor soil management. The two main impact channels are likely to be agriculture and road infrastructure. In agriculture, the increased uncertainty around future precipitation levels in Malawi will likely result in higher variability in crop yields. Climate change is projected to exacerbate preexisting environmental degradation challenges, including soil erosion. These effects are particularly problematic due to Malawi’s high poverty rate, lack of economic diversification (the agriculture sector represents one-third of the economy and employs over 70 percent of the workforce), and significant dependence on rainfed production (about 80 percent of the population). Climate change is likely to significantly impact Malawi’s road infrastructure, mainly due to increased risk of flooding, which would have broader economic and social knock-on impacts. |

| Abstract: | Mozambique is already vulnerable to extreme weather events and climate change is projected to exacerbate their frequency and intensity. The occurrence of cyclones and flooding has increased in recent years and the trend is expected to continue. The country’s coast—where 60 percent of the population, the three biggest cities, and critical infrastructure are situated—is most exposed to climate change-related risks, including damage from cyclones and projected sea level rise. Densely populated and low-lying regions, such as Zambezia, Nampula, Sofala, and Maputo Provinces, are particularly exposed to risks from flooding. More broadly, climate change is projected to increase average temperatures across the country and to result in higher variability in precipitation, especially in the south. The most critical economic sectors vulnerable to climate change in Mozambique are agriculture, transport, and potentially energy. In agriculture, maize is likely to be the most affected key crop. This can pose risks to food security (alongside expected higher food inflation because of climate change), given maize’s widespread cultivation and role in nutrition. The impact on other crops is likely to be more limited, and to a large extent driven by damages from increased frequency of extreme weather events. This could exacerbate challenges in the sector, which is already constrained by low productivity and limited arable areas. That said, climate change could create some opportunities; for example, rice yields are projected to improve. Most studies project agricultural production in the central region to be most adversely affected by climate change, albeit the impact varies by crop and within regions. Mozambique’s transport infrastructure is highly vulnerable to climate change due to the projected increase in flooding, the low proportion of paved roads, their limited interconnectivity, and the vulnerability of ports to cyclones and storm surges. Damages to Mozambique’s transport sector are likely to have knock-on effects to other sectors and can have significant regional implications, as the country serves as a conduit for landlocked neighboring countries. Infrastructure damages, alongside the projected coastal erosion, may severely affect the tourism sector. Furthermore, Mozambique’s high dependence on hydropower exposes it to losses from rainfall variability, which is expected to increase. The country’s largest hydropower plant is located downstream on the Zambezi River, which various studies project to dry up due to climate change. Increased water use in upstream countries (such as because of greater irrigation needs and in response to growing populations) could also pose risks to Mozambique’s hydropower sector. |

| Abstract: | Economic resilience within the agrifood system is becoming increasingly crucial for assuring sustainable development. This is particularly so in regions with volatile and fragile environments, including Central Asia. Evidence remains scarce regarding what factors can enhance the economic resilience of agents within the agrifood system, including the resilience of productivity and technical efficiency. We partly fill this knowledge gap using the unique panel datasets of farm enterprises in Uzbekistan and southern Kazakhstan, collected in 2019 and 2022, during which these enterprises experienced significant economic shocks in input prices. Using novel methods that combine Inverse Probability Weighting and panel stochastic frontier analyses models, we show that farmers who received more agricultural training and who had been granted greater autonomy in their production decisions in 2018 experienced greater resilience in technical efficiency despite the need to reduce the use of chemical fertilizer and oil/diesel in response to their price surges. Our findings suggest that providing critical public goods like information (related to training) and enabling environment (related to decision-making autonomy) can potentially enhance the resilience in the technical efficiency of farm enterprises. Furthermore, with chemical fertilizer and oil/diesel being potentially environmentally harmful inputs, these farmers also indirectly demonstrated resilience toward environmental sustainability. |

| Abstract: | The latest report on "Repairing Broken Food Trade Routes Ukraine – Africa” covers: Production and trade risks for global food security Investment risks for Ukraine Diversification and processing as partial solutions to the export problems Importance of Ukraine’s victory for global food security This project has received funding from the European Union's Horizon 2020 research and innovation programme “Making Agricultural Trade Sustainable” (MATS) programme (https://sustainable-agri-trade.eu/). The role of MATS/WTI in this programme is to identify and explore “broken” Ukrainian - African food trade routes due to the Russian invasion of Ukraine. Starting with a food trade flow chart pre- and post-24 February 2022, it will assess, first, whether Ukrainian (or African) traders can again supply these products (Output 1). Failing that, whether the new EU-financed “Crisis Management” (or another) programme can possibly make up for lost Ukrainian agrifood exports (Output 2). It will also identify alternative exporters (if any) that might already have filled in agrifood demand in Africa (Output 3). Importantly, the Project also looks at the potential effect of these developments on competing farm production in Africa (Output 4).

| Abstract: | Interventions/Innovations The Africa RISING (AR) program in Malawi was implemented in Dedza and Ntcheu districts in the country’s Central region, primarily using an on-farm participatory approach. The program supported cropping system improvements through promotion of improved varieties and quality seeds for beans, soybeans, groundnuts, and pigeon peas. It also aimed to foster the adoption of sustainable and productivity enhancing practices (e.g., legume legume or maize-legume intercropping and consistent grain-legume rotation) and nutrient cycling for soil enrichment (e.g., building soil organic matter, implementing a rainfall responsive nitrogen fertilization strategy). Livestock interventions focused primarily on supplementary feeding of goats to promote animal health and weight gain. Increased agricultural productivity and the processing of more nutritious grain legumes were considered prime channels for improving household income, diet diversity, and overall nutrition. |

| Abstract: | The relevance of the study is determined by the fact that suburban agricultural enterprises are becoming innovative ‘locomotives’ of rural development and form the epicenter of the agrarian and economic contradictions in contemporary Russia. The study aims at a comprehensive interdisciplinary analysis of the scale, forms and branches of the suburban and urban agriculture in Russia, and at identifying the technological and social-ecological vectors of its development. The subject of the study is social transformations determined by the technological schemes and industrial-agricultural clusters in the suburban areas of Russian regions. The study combines methods of quantitative (statistical data, secondary analysis) and qualitative approaches (observations, semi-formalized expert interviews) within the case study. The results of the study include the typology of social transformations taking place in cities and their suburban areas with the intensive development of new agricultural practices and enterprises; the demographic characteristics of the employed in such industries; and the most important sectoral and institutional forms of urban and suburban agriculture. The paper concludes that the projects for the creation of new technologies and branches of agricultural production in suburban areas are not so much focused on the immediate commercial goals as motivated by the interests of establishing a system of smallscale agricultural ‘cells’ designed to provide urban families with quality local products. Such a diversification of food production can provide non-standard employment for citizens and increase their level of food security. The novelty of the study is determined by the analysis of the suburban phenomenon not as a reserve-serving territory but as a multifunctional social-economic entity capable of performing both economic-auxiliary and such non-standard functions as the production and organization of social-cultural phenomena in a special rural, social-ecological space. The paper provides some recommendations such as closer links between rural and urban food systems; and a system of special seminars and courses on the basis of agricultural universities in the interests of innovative agricultural enterprises in the suburbs. |

| Abstract: | In recent decades, there has been a palpable shift in the commodity composition of world agri-food trade away from the traditional primary (unprocessed) products mostly exported from developing countries. However, this structural change in trade patterns and its policy implications have so far received scant attention in policy making in most agricultural-resource rich developing countries. Policy makers are still wedded to the conventional division of primary products and manufactured goods that lumps together processed food with primary (unprocessed) agri-food products. This paper aims to draw attention to this policy oversight by examining the experience of Sri Lankan in processed food exports against the backdrop of the experiences of the other countries is the Asian region. The analysis uses a new dataset that systematically delineate processed food from the traditional primary good products, The analytical narrative of inter-country pattern of export performance shows that, unlike primary commodity dependence, exporting processed food is positively associated with the state of economic advancement of countries. The results of the econometric analysis suggests that export success of a country is determined by a combination of growth of world demand, the domestic agricultural resource endowment and the conduciveness of the policy regime for global economic integration. |

| Abstract: | Climate change is projected to cause an increase in average temperatures in Zambia and a decline in rainfall, particularly in the southern and western regions. The country experiences high rainfall variability, which climate change is expected to exacerbate, resulting in likely higher frequency and intensity of already reoccurring extreme weather events, such as droughts and floods. The combined effect of the temperature and precipitation projections is anticipated to cause a decrease in water availability at national level and to adversely affect the Zambezi, Kafue, and Luangwa River Basins. Overall, these trends will exacerbate existing vulnerabilities in southwestern Zambia, as the region is already prone to droughts (as well as floods in some parts). On the other hand, the northern parts of the country are projected to experience a slight increase in rainfall and to be overall relatively positively affected by climate change. The key sectors most likely to be significantly affected by climate change in Zambia include agriculture, road infrastructure, and energy. In agriculture, the key risk stemming from climate change is the projected lower maize yields, as this is the country’s staple crop. Other crops are also expected to be adversely affected by higher temperatures, reduced rainfall, and increased occurrence of extreme events, particularly in southern and western Zambia. That said, changing climate conditions could create new agricultural opportunities in the north. Climate change is projected to negatively affect the livestock subsector, which will increase food security risks, particularly for subsistence farmers. In road infrastructure, the projected higher occurrence of flooding, especially in Lusaka Province, could have a knock-on effect for the rest of the economy, particularly if it damages key international corridors passing through this region and/or affects domestic supply chains. Zambia is significantly reliant on hydropower and is already experiencing severe power cuts due to drought. The risks in the sector are exacerbated by the location of key hydropower plants in the southern parts of the country and the projected drying up of main river basins. The electricity shortages have spillover effects on the rest of the economy, including the copper industry, Zambia’s key export. This has international implications, as Zambia is a top copper producer worldwide, and demand for copper is expected to increase significantly due to its crucial role in various green technologies. Thus, absent adaptation measures, the adverse impact of climate change in Zambia could affect global mitigation efforts and strategies. |

| Abstract: | Green insurance is an innovative tool to help producers manage (perceived) risks of transitioning to more environmentally-friendly crop management strategies. It is is not yet part of the agricultural policy toolbox nor is it marketed privately on a large scale. We here investigated the best design, uptake determinants and potential pesticide reduction from green insurance for a decision support system (DSS) for pesticide reduction in grape-vine production. This is an important example, as pesticide use reduction is high on the agricultural policy agenda and grape-vine production is a major contributor to global pesticide use. For our analysis, we conducted a Discrete Choice Experiment with 412 French vine growers. We find that 48% to 60% of growers are likely to subscribe to green insurance, with differences across contract types and prices. Producers transitioning to organic production are the most interested in the contract. All types of producers exhibit on average lower interest for group contracts and index-based insurance than for the traditional individual loss-based contract. Using data from field experiments on DSS performance in reducing fungicide use, we estimate that adopters could reduce their fungicide use by 45% on average. Our results suggest that green insurance could be a cost-effective tool to advance ambitious EU Green Deal pesticide policy goals, and more broadly, support the transformation to more environmentally-friendly farming practices. |

| Abstract: | By developing a conceptual analysis, this research explores the possibility of fostering a convergence between digitalization and sustainability, also named digitainability. This convergence is often seen as an opportunity to solve the various challenges the agrifood sector faces nowadays, especially those of feeding more people without deteriorating the environment and creating social divides and, at the same time, managing specific risks related to climate change, biodiversity loss, and hunger. The research describes how open innovation is becoming an imperative and explains the contribution of startups in the development of these new innovative initiatives. It also explains how sustainability considerations are closely linked to the development of servitization in the business context. Finally, it explores how these changes impact established companies, forcing them to develop ambidextrous innovation strategies to maintain and support their competitive advantage. In doing so, the paper illustrates some of the well-known effects of this ongoing change, while identifying the opportunities created and the challenges for which more research is still needed. |

| Abstract: | The U.S. Department of Agriculture (USDA) has monitored the extent and severity of food insecurity in U.S. households for more than 25 years. Data on food security is collected annually as part of the Current Population Survey Food Security Supplement (CPS-FSS). USDA, Economic Research Service (ERS) undertook a process to update the survey instrument used for CPS-FSS data collection to ensure that questions accurately reflect respondent engagement with the current food environment and to decrease nonresponse on select questions and lower respondent burden. The updated instrument was created through a process of expert content review and cognitive testing and implemented by the U.S. Department of Commerce, Bureau of the Census in a split-panel data collection in September 2020. A portion of the survey sample received the revised survey instrument, and the other portion received the standard survey instrument, which was implemented in 1995 and has been consistent since 2008. This process ensured that any unforeseen outcomes of the revisions did not affect the annual food security estimates that USDA, ERS produced. The split panel forms two samples that were weighted to represent the U.S. population. Estimates for food spending, food security, and participation in Federal and community nutrition assistance were compared. Based on the analysis of the split-panel test, the test instrument performed well. The differences observed in the test and the standard instrument for food spending and community nutrition assistance were expected, given the changes in the survey questions. The food security measure is based on the Rasch measurement model. Rasch analysis was used to assess the comparability of the food security questions across the split-panel samples. The analysis confirmed that the minor changes to the food security section are unlikely to affect the measurement of food insecurity or affect the comparability of year-to-year estimates. |

| Abstract: | We study the role of a multifaceted ultra-poor graduation program in protecting household wellbeing and women’s welfare from the effects of localized droughts in Ethiopia. We use data from a large experimental trial of an integrated livelihood and nutrition intervention that supplemented the consumption support provided by Ethiopia’s Productive Safety Net Program (PSNP), conducted within a sample in which all households were beneficiaries of the PSNP. We match three rounds of household survey data to detailed satellite weather data to identify community-level exposure to droughts. We then exploit random assignment to the graduation program to evaluate whether exposed households show heterogeneous effects of drought on household food security and livestock holdings, women’s diets and nutritional status, and prevalence of intimate partner violence (IPV). We find that droughts have substantial negative effects on these outcomes, but the intervention serves to consistently moderate these effects, and for some outcomes (particularly diets and nutrition and IPV), the intervention fully protects households from any adverse drought affects. A further analysis exploits variation across treatment arms that received different program elements and suggests that the primary mechanism is enhanced household savings. |

| Abstract: | Substantial model variability exists regarding the likely meteorological impact of climate change on Kenya, particularly with respect to future precipitation levels. Significant regional differences are expected, largely due to Kenya’s diverse climate profile. Overall, temperatures are projected to increase while future precipitation levels are highly uncertain. Climate change is expected to significantly affect coastal areas, including because of sea level rise risks, stronger winds, and an overall warmer and drier climate. This will likely harm important ecosystems, including wetlands, mangroves, and coral reefs. Some models project that arid and semi-arid areas may become drier and hotter, which would exacerbate preexisting water scarcity and agricultural challenges for the already vulnerable communities living there. That said, these projections are not corroborated by all models. The climate change impact on other areas, particularly south and west of Mount Kenya, could generally be positive, as it would provide even better conditions for agriculture. The key climate change risk for Kenya is from extreme events, in particular droughts and floods. The frequency and intensity of such events is likely to increase because of climate change. They also often lead to adverse knock-on effects, such as soil erosion, land degradation, and pest breakouts. Overall, Kenya’s updated Nationally Determined Contribution (NDC) (2020) estimates that between 2010 and 2020, adverse climate change-related events led to annual socioeconomic losses of 3–5 percent of total gross domestic product (GDP). |

| Abstract: | State decentralization is often promoted to improve public service delivery. However, its effects on forest conservation are ambiguous. Decentralization might not only improve local forest governance, but also change the incentives to promote agricultural expansion into forests. This study focuses on the power devolution caused by the proliferation of new administrative units in Indonesia. The discontinuous changes in government responsibilities at new administrative borders provide exogenous spatial variation to study forest outcomes. Using a spatial boundary discontinuity design with 14, 000 Indonesian villages, we analyze the effects of 115 district splits between 2002 and 2014. Results show a 35% deforestation decline within new districts relative to existing districts both immediately before and after splits. In presplit years, this can be explained through agricultural divestment by existing districts on territories that will be lost. In post-split years, the short-term forest conservation benefits seem to be rooted in temporary administrative incapacity to attract agricultural investments. |

| Abstract: | The U.S. is the world’s largest source of industrial wood production (FAO, 2019), with the U.S. South accounting for half of total production (Howard and Liang, 2019). Most of this production is from the “pine belt, ” which includes states like Mississippi, Alabama, and Georgia. Unlike these pine-belt states, Tennessee is primarily a hardwood state (deciduous trees), which are rela- tively high value and make an important contribution to Tennessee’s economy (Pelkki and Sherman, 2020). Tennessee’s forestry activity tends to be in rural areas and is often smaller scale than other industries, so the economic and social importance of the wood products industry are often underappreciated. It is estimated that forestry in Tennessee provides over 85, 000 jobs and has an annual economic impact of over $21 billion (Menard, English and Jensen, 2021). Tennessee is among the top ten states in terms of the relative importance of forestry, alongside Maine, Wisconsin, and Oregon (Pelkki and Sherman, 2020). Tennessee’s forestry industry is globally connected, and many sawmills in the state are dependent on global sales. About half of the higher-grade hardwood lumber produced in Tennessee is exported (Luppold et al., 2018). Consequently, changes in global markets can have a significant impact on Tennessee’s forest economy. In this report, we discuss the economic impact of Tennessee’s forestry exports. We examine the export changes in 2022 (relative to 2021) across destination countries (e.g., China, European Union) and by product (e.g., oak lumber, hardwood logs, barrels), and further assess the full economic impact of export sales on income and jobs at the state level. Forestry exports are not just important to Tennessee but to the entire country. U.S. sales of forest products to foreign countries were $10.5 billion in 2022. In the context of agriculture and related products (as defined by the U.S. Department of Agriculture), 1 forest products are an important share of total U.S. exports, with global sales comparable to America’s top agricultural exports: beef ($11.8 billion), dairy products ($9.5 billion), cotton ($8.9 billion), and wheat ($8.3 billion). Forestry exports in Tennessee ($194 million in 2022) ranked third among agricultural and related exports behind distilled spirits and cotton (USDA, 2023). Exports of forest products were negatively impacted by the U.S. trade war with China in 2018 and 2019 and the COVID-19 pandemic in 2020. This was the case for both the U.S. and Tennessee. The pandemic had a significant impact on global sales due to supply and demand disruptions in the global market for finished wood products (e.g., furniture) and the interrelated market for raw materials and inputs (e.g., logs and lumber) (Muhammad and Taylor, 2020). These effects were in addition to the negative impacts of China’s retaliatory tariffs on U.S. timber, which are still in place (Muhammad et al., 2022). Exports of forest products from 2019 to 2022, nationally, regionally, and for Tennessee are reported in Table 1. From 2020 to 2021, U.S. exports increased by $2.1 billion. In 2022, exports continued to increase by $756 million (nearly 8%) when compared to the previous year, reaching 10.5 billion. This increase was mostly in Southern states, followed by Western states. U.S. and Tennessee exports further recovered in 2022 by 8% and 4%, respectively, when compared to 2021 (USDA, 2023). The increase in exports sales in 2021 and 2022 was a welcomed turnaround given the declines experienced in previous years. |

| Abstract: | This factsheet addresses the concepts of "Hazard Analysis Risk based Preventative Controls" (HARPC) and "Hazard Analysis Critical Control Point Plans" (HACCP). The establishment of HARPC and HACCP protocols are key pillars when establishing necessary preventative controls outlined under the Food Safety Modernization Act and required for some, but not all, businesses that manufacture, process, or otherwise sell food for human consumption. This document also addresses what entities are required to maintain preventive controls and which entities are typically exempt from these rules, as well as the components of these control plans. |

| Abstract: | Managing biotic stress, such as pests, diseases, and weeds, remain critical in enhancing the productivity of agrifood systems in developing countries, including Nigeria. The public sector continues to seek solutions for efficient and effective measures for addressing these biotic stresses, ranging from varietal technologies, improved crop husbandry, and the application of agrochemicals. The field-level evidence remains scarce regarding the effectiveness of these measures in developing countries like Nigeria. Furthermore, increasing climate uncertainty poses further challenges in identifying effective measures. This study assesses the damage abatement effects of agrochemicals in Nigeria and how these effects are affected by weather shocks. We extend the standard damage abatement framework to 4 waves of farm panel data to minimize the potential bias due to the endogeneity in agrochemical use decisions. Our results indicate that weather shocks have significant effects. In particular, rising nighttime minimum temperatures above 20 ℃ have significantly increased damage abatement effects of pesticides in Nigeria. This is possibly because of increased pest activities induced by the warmer nighttime temperatures, which, in the absence of pesticide uses, would cause more significant damage to crops. These results hold for all crops combined, as well as individual crops, including cowpea and maize, for which Nigeria has intensified its effort in pest control through both agrochemicals and Bt varieties in recent years. |

| Abstract: | Climate change, primarily driven by human activities, is becoming one of the most urgent global challenges of our time. Despite lingering doubts about climate change in some research documents, strong consensus within the scientific community still affirms that global surface temperatures have risen in recent decades. Over the past decade, significant efforts have been made by humans to address the climate change crisis, resulting in certain impacts in combating climate change and raising awareness about its consequences. However, the question remains: Are we heading in the right direction to effectively address this crisis, or do we need to reconsider our approach? This essay will examine some of major achievements in the fight against climate change, the increasing awareness of its impacts, the escalating severity of the climate crisis, and whether our actions are on the right track or require reevaluation. |

| Abstract: | The European Union designates 26% of its landmass as a protected area, limiting economic development to favor biodiversity. This paper uses the staggered introduction of protected-area policies between 1985 and 2020 to study the selection of land for protection and the causal effect of protection on vegetation cover and nightlights. Our results reveal protection did not affect the outcomes in any meaningful way across four decades, all countries, protection cohorts, and a wide range of land and climate attributes. We conclude that European conservation efforts lack ambition because policymakers select land for protection not threatened by development. |

| Abstract: | This study investigates the risks and vulnerabilities affecting food supply and food security in the EU, including differences across Member States, sectors and stages of the EU food supply chain. The study uses data from a systematic literature review, semi-structured interviews and an online survey of key stakeholders, and employs qualitative and quantitative methods to analyse risks and vulnerabilities. It finds that the EU food supply chain faces a broad range of risks and sheds light on the factors that make it vulnerable to these risks. The analysis identifies key characteristics of risks, such as origin, time horizon, likelihood of occurrence, potential impact and exposure. Key risks to food supply and food security are highlighted, as are the main risks threatening different Member States (including the outermost regions) and the different sectors and stages of the EU food supply chain. Emerging risks that warrant further attention are also identified. The study provides a basis for strategic decision-making by highlighting the sources of risks and potential areas of intervention to reduce the vulnerabilities of the food supply chain. Its findings will support EU policymakers, particularly within the European Food Security Crisis Preparedness and Response Mechanism, in improving the preparedness of the EU food supply chain for future crises. |

| Abstract: | After reaching China from Europe in 2018, the African swine fever (ASF) virus spread throughout the country, dramatically reducing China’s pork supplies. This report investigates the impacts on China’s pork market that resulted from the virus and how China’s increased demand for imported pork affected markets for pork-exporting countries. China’s swine herd experienced a 30-month cycle of decline and recovery, as the country lost an estimated 27.9 million metric tons of its pork output. Pork prices in China more than doubled despite a surge of pork exports from the European Union, United States, Canada, Brazil, and other countries. Pork exports to China prompted smaller price increases in exporting countries’ pork markets. As China’s domestic pork supplies recovered about 3 years after the first ASF outbreaks, Chinese pork prices declined to near their pre-ASF level. U.S. pork exports to China declined but remained above their pre-ASF volume. Volatility in China’s pork market is an ongoing source of uncertainty for exporters despite the rebound in China’s production. |

| Abstract: | This study evaluates the impact of Africa RISING, a sustainable intensification (SI) program, implemented in Bougouni, Yanfolila, and Koutiala cercles in southern Mali beginning in 2012. Using a participatory action research framework, the program validated and promoted alternative SI options including fertilized groundnut and sorghum, crop-legume intercropping, intercropping of two compatible legumes, access to extension services, and fertilizer microdosing, while preserving ecosystem services in the face of projected population growth and climatic changes. Impact is estimated on several SI indicators and domains using two rounds of quasi-experimental panel data (surveys conducted in 2014 and 2022) and difference-in-differences techniques. The unique study design allows us to estimate the impact of Africa RISINg by comparing outcomes among program beneficiaries with two different counterfactual groups—one located inside program villages (within-village comparison) and another in non-program (control) villages (out-of-village comparison) on several indicators across five SI domains— environment, productivity, economic, human, and social. We also conduct a placebo test comparing non-beneficiaries in the two counterfactual groups. We find no statistically significant differences among households in the within-village and out-of-village comparisons, most likely because of misreporting of program participation. Overall comparisons between households in target and non-target villages show a positive impact of AR on environmental variables such as access to extension services, implementation of intercropping techniques, and adoption of improved crops; on productivity variables such as green bean yield; and on economic variables such as an increase in the non-agricultural wealth index; but no statistically significant effect on human and social indicators, namely household dietary diversity, food consumption scores, and nutritional indicators for children 0–59 months old and women 15–49 years old. Estimates based on within-village, out-of-village, and placebo comparisons suggest important insights about the challenges in assessing the impact of agricultural programs in general and, specifically, participatory multi-intervention programs in the presence of sample (self-)selection and spillovers. Our study highlights useful empirical lessons learned to inform future program design and impact assessments. |

| Abstract: | The TETRAE project "Accelerating and Accompanying Transitions: Contributions and Impacts of Agroforestry in New Aquitaine" (AC²TION), aims to study the environmental and socio-economic performance of agroforestry systems (association of trees and crops on the same agricultural plot) in south-western France. As part of research component 3 of the TETRAE AC²TION project, we propose to present the methodological approach used to assess the environmental and socio-economic performance of field crop agroforestry systems at farm level in the Charentes region, using a multi-criteria decision-support method. By storing carbon, supporting a rich biological life in the soil and sheltering auxiliary insects in the canopy, trees play an active role in erosion control and soil conservation. Tree rows also play an important role as windbreaks and barriers to the atmospheric diffusion of pesticides. Trees create a habitat for crop pest beneficials, especially in areas where hedges and copses have long since disappeared. They can also act as a reservoir for fungal and bacterial pathogens. They also make the rural landscape a pleasant place to live. Agroforestry is therefore one of the levers that can support the agroecological transition to mitigate the effects of climate change, facilitate the implementation of other agroecological practices and provide ecological functionalities. The originality of our approach is twofold: 1) relatively few studies and applications have been carried out in New Aquitaine, in comparison with other regions such as Montpellier 2) at the heart of our questioning are the quantitative and qualitative decision levers and obstacles of agroforestry farmers in field crops. We propose to identify and classify their positive or deleterious effects, integrating them into an analysis of overall performance (environmental and socio-economic). Our methodological approach involves surveys and interviews with field crop agroforestry farmers, and analysis of the survey results, identifying the socio-economic and environmental decision factors involved in the transition. We will then use multi-criteria decision-support methods: Electre Tri-nC and Electre III to evaluate agroforestry performance. Qualitative and quantitative criteria will be used to understand the impact of such a system on microclimate and biodiversity. The same applies to soil enrichment for mineral plant nutrition, and positive externalities for humans. But agroforestry should also help reduce crop pathogens, with a view to reducing pesticide use. Anchored in the regional fabric of the Neo-Aquitaine region, the project is part of a strong partnership approach, with the French Agroforestry Association providing co-leadership. The Chambers of Agriculture of Charente Maritime and the Interdepartmental Chamber of Agriculture of Deux Sèvres and Charente-Maritime are also partners, as are several farmers. Our contribution to the project is also in collaboration with various arable and agroforestry farmers, based mainly in the Charentes region. Identification and classification of socio-economic and environmental decision criteria for the overall performance of field crop agroforestry farms. |
| Abstract: | Le projet TETRAE « Accélérer et accompagner les transitions : Contributions et Impacts de l'Agroforesterie en Nouvelle Aquitaine » (AC²TION), vise à étudier les performances environnementales et socio-économiques des systèmes agroforestiers (association dans une même parcelle agricole, d'arbres et de cultures) dans le Sud-Ouest de la France. Inscrit dans le volet de recherche 3 du projet TETRAE AC²TION, nous nous proposons de présenter la démarche méthodologique d'évaluation des performances environnementale et socio-économiques des systèmes agroforestiers grandes cultures à l'échelle des exploitations agricoles en Charentes, avec la méthode multicritère d'aide à la décision. En stockant le carbone, en permettant une vie biologique riche dans le sol et en abritant des insectes auxiliaires dans la canopée, les arbres ont un rôle actif contre l'érosion, ainsi que dans la conservation des sols. Les rangées d'arbres jouent également un rôle important en tant que brise-vent et barrière à la diffusion atmosphérique des pesticides. Les arbres créent un habitat pour les auxiliaires des ravageurs des cultures, surtout dans les régions où les haies et les bosquets ont disparu depuis longtemps. Ils peuvent également constituer une réserve de pathogènes fongiques ou bactériens. Ils rendent le paysage rural agréable pour la population. L'agroforesterie est donc l'un des leviers qui permet d'accompagner la transition agroécologique pour atténuer les effets du changement climatique, faciliter la mise en œuvre d'autres pratiques agroécologiques et fournir des fonctionnalités écologiques. L'originalité de notre démarche est double : 1) relativement peu d'études et applications en Nouvelle Aquitaine ont été effectuées, en comparaison avec d'autres régions comme en territoire montpelliérain 2) au cœur de notre questionnement sont les leviers de décision et freins tant quantitatifs que qualitatifs des exploitants agroforestiers en grandes cultures. Nous nous proposons d'en identifier et d'en classer les effets positifs ou délétères en les intégrant dans une analyse de la performance globale (environnementale et socio-économique). Notre démarche méthodologique met en œuvre des enquêtes et entretiens auprès d'exploitants grandes cultures en agroforesterie, et d'analyser les résultats d'enquêtes, en identifiant les facteurs de décision socio-économiques et environnementaux de la transition. Ensuite, nous utiliserons des méthodes d'aide à la décision multicritères : Electre Tri-nC et Electre III pour réaliser l'évaluation des performances agroforestières. Des critères qualitatifs et quantitatifs permettront de comprendre les impacts d'un tel dispositif sur le microclimat, et la biodiversité. De même, sur l'enrichissement du sol pour la nutrition minérale des plantes, et les externalités positives pour l'homme. Mais l'agroforesterie devrait aussi permettre de réduire les pathogènes des cultures en vue de réduire l'utilisation des pesticides. Ancré dans le tissu régional néo-aquitain, le projet s'inscrit dans une démarche partenariale forte, avec le co-leadership du projet assuré par l'association française d'agroforesterie. Les chambres d'agricultures de Charente Maritime et la chambre interdépartementale d'agriculture Deux Sèvres et Charente-Maritime sont également partenaires, ainsi que plusieurs exploitants agricoles. Notre contribution au projet est en collaboration avec aussi différents exploitants agricoles en grandes cultures et agroforesterie, basés majoritairement dans les Charentes. Une identification et une classification des critères de décision socio-économique et environnementaux pour la performance globale des exploitations grandes cultures en agroforesterie sera donc livrée. Une étude de la faisabilité de transposabilité / montée en généricité de nos résultats de modélisation à un autre contexte néo-aquitain ou agroforestier est envisageable. Les résultats du volet 3.1 de recherche au projet multidisciplinaire AC²TION a pour ambition de mettre en valeur la complexité des effets de levier ou de contrainte, de comprendre leur interdépendance et leur hiérarchisation et favoriser le développement de cette voie de transition agroécologique en région Nouvelle Aquitaine, dans un contexte d'adaptation au changement climatique. Outre l'aspect enseignement et recherche (stage et post doc), des retours avec les acteurs terrain et des valorisations scientifiques sont prévues. Cette étude sera utile pour fournir aux acteurs de terrain une aide à la décision pour leur changement de système de gestion, notamment ceux qui sont dans des processus intensifs. Elle est également très utile localement pour réconcilier la population urbaine avec les pratiques agricoles. |

| Abstract: | This study evaluates the impact of Africa RISING, a large-scale sustainable intensification (SI) program that has been implemented in Central Malawi’s Dedza and Ntcheu districts beginning in 2012. Using a participatory action research framework, the program validated and promoted alternative SI options including fertilized maize, maize-legume intercropping, intercropping of two compatible legumes, cereal-legume rotation, and double-row planting of legumes. Impact is estimated on several SI indicators and domains using two rounds of panel data and difference-in-differences techniques. The unique study design allowed us to estimate impact by comparing outcomes among program beneficiaries with two different counterfactual groups—one located inside program villages (within village comparison) and another in non-program (control) villages (out-of-village comparison). We also conduct a placebo test comparing non-beneficiaries in the two counterfactual groups. The within-village comparison shows positive impact on several agricultural and economic indicators including access to agricultural information, value of harvest, on-farm diversity, labor productivity, annual net household income, per capita household consumption expenditure, household wealth, commercial orientation, and household dietary diversity score. We do not find a statistically significant impact on human indicators such as child and maternal nutrition. Estimates based on within-village, out-of-village, and placebo comparisons suggest important insights about the challenges in assessing the impact of agricultural programs in general and, specifically, participatory multi-intervention programs in the presence of sample (self-)selection and spillovers. Our study highlights important lessons learned to inform future program design and impact assessments. |

| Abstract: | This article analyses several possibilities to valorize prickly pear farming in Algeria, a context dominated by semi-arid ecosystems. It uses sociotechnical and evolutionary approaches in order to understand the new dynamics happening within this sector. Based on field surveys and literature review, this study shows that the production and processing of prickly pear by-products present a high potential, but remains largely under-exploited. Production is mostly artisanal, collection uses traditional practices and marketing is dominated by unstructured and informal channels. The development of processing activities is fairly recent and its dynamic reflects the high interest for this emerging sector by adopting certain practices already observed elsewhere. Finally, an important constraint is foreign market entry. Due to the partial failure of producer's commercial export strategies', local outlets remain dominant. |

| Abstract: | This paper describes an empiric study of aggregation and deliberation—used during citizens' workshops—for the elicitation of collective preferences over 20 different ecosystem services (ESs) delivered by the Palavas coastal lagoons located on the shore of the Mediterranean Sea close to Montpellier (S. France). The impact of deliberation is apprehended by comparing the collectives preferences constructed with and without deliberation. The same aggregation rules were used before and after deliberation. We compared two different aggregation methods, i.e. Rapid Ecosystem Services Participatory Appraisal (RESPA) and Majority Judgement (MJ). RESPA had been specifically tested for ESs, while MJ evaluates the merit of each item, an ES in our case, in a predefined ordinal scale of judgment. The impact of deliberation was strongest for the RESPA method. This new information acquired from application of social choice theory is particularly useful for ecological economics studying ES, and more practically for the development of deliberative approaches for public policies.. |

| Abstract: | Over the past two decades, Rwanda has positioned itself as a leading producer of specialty coffee. The shift away from ordinary coffee began in the early 2000s and was buoyed by international donors, NGOs and the government. They all supported the nascent specialty coffee industry by providing a combination of technical assistance and funding to invest in coffee washing stations. Coffee washing stations (CWS) are a pivotal piece of the value chain in Rwanda since it is where ordinary coffee undergoes a process that turn it into specialty coffee. The policy of shifting to specialty coffee has been significantly beneficial to Rwanda. However, there was a rush to build a large number of CWS throughout the country which has resulted in an over capacity of these plants and fierce competition among them for the purchase of cherry coffee from farmers. In an attempt to shore up the industry the Government implemented a zoning policy which effectively is a trade barrier to artificially maintain a high margin between the input price of cherry coffee and the sales price of coffee received by the CWS. This study uses a cost-benefit analysis to estimate the economic welfare loss to Rwanda of these policies. Over a ten year period the present value of the economic loss is estimated to be $73 million. An increased competition in the market for cherry coffee would raise the price of cherry coffee at the expense of the profits of CWS owners. If such a policy were implemented coffee growers could potentially receive up to 150% more from their sales of cherry coffee, or $45 million per year. These enhanced revenues would allow famers to finance the replanting of their coffee fees and maintain the sustainability of this sector. |

| Abstract: | I present new evidence of the effects of climate shocks on political violence and social unrest. Using granular conflict and weather data covering the entire continent of Africa from 1997 to 2023, I find that exposure to El Ni\~no events during the crop-growing season decreases political violence targeted at civilians during the early postharvest season. A moderate-strength El Ni\~no event results in a three percent reduction in political violence with civilian targeting in croplands compared with the benchmark levels of this conflict evaluated at average cropland size and average growing-season exposure of local weather to El Ni\~no shocks. Because this effect manifests itself only in cells with crop agriculture and only during the postharvest season supports the idea that agriculture is the key channel and rapacity is the key motive connecting climatic shocks and political violence. Reassuringly, the magnitude of the estimated effect increases substantially, in one instance more than doubles, when I use subsets of data that are better suited for unveiling the proposed mechanism. This study advances knowledge of the relationship between climate and conflict. And because El Ni\~no events can be predicted several months in advance, these findings can contribute to creating a platform for early warning of political violence, specifically in predominantly agrarian societies in Africa. |

| Abstract: | Climate change impacts international trade. The literature suggests that thisrelationship is driven by the damage to infrastructure and reduced productivitycaused by this global phenomenon. Furthermore, recent research indicates thatthe impact on energy consumption could explain the real effects of disasters inthe United States. Using a sample of 67 countries during the period 1986–2016, we analyze whether the secular increase in global temperatures and theoccurrence of drastic climate events (wildfires, floods, extreme temperatures, epidemics, insect infestations, storms, droughts, and landslides) affectcountries’ energy consumption and labor productivity, which can subsequentlyimpact international trade. By estimating a theory-based gravity model, ourresults suggest that energy intensity is the channel through which risingtemperatures affect international trade. Furthermore, the impact of events oninternational trade does not seem to be channeled through either energyefficiency or labor productivity. A deeper analysis suggests the key role playedby China in this regard. The Chinese government’s enormous investment ininfrastructure since 1998 to manage these types of disasters seems to be themost reasonable explanation. |

| Abstract: | There is growing recognition of the role of land in achieving key Sustainable Development Goals such as gender equality and reduced inequalities. Yet, little is known about the fundamental question: how much land do women hold and control in India? A key reason for this is the informational gap in popular datasets and the work in India. Current work does not map (i) the de jure rights of women as reflected in land records; (ii) the linkage between de jure rights and de facto variables such as (a) women's control over their land assets or (b) their perceptions of tenure security. These elements together make up a whole, and a lack of understanding of one or the other presents an incomplete picture of the question of women's land ownership. The primary objective of this study is to undertake an accurate and comprehensive mapping of women's land rights, which converges de jure rights; and de facto control over land and perceptions of tenure security using a novel methodology which is a combination of desk and fieldwork. We first undertake mapping of two land tenures - ownership and lease in rural and urban districts in the sample state using parcel-level information in textual land records. We select Maharashtra as the environment under examination for three reasons: (i) the state has made considerable progress in digitising land records (ii) our previous fieldwork confirms high accordance between the ownership information on the records and ground (iii) the state has also digitised urban land records. We then select a sample set of parcels where women are de jure rights holders. We conducted a field survey to study two de facto variables: (a) their control over their land and (b) their perceptions of tenure security. In doing so, we propose a scalable and nuanced methodology to study the complex question of women's land. Our findings provide a data-backed foundation for answering questions on women's rights in land, their control over their land and their perceptions of tenure security for better-informed policy interventions. |

| Abstract: | The Indian state suffers from a deep-rooted capacity problem that manifests in various ways depending on the field of government functioning. In the field of land, the problems in capacity manifest in slow processes, low enforcement, outdated laws, low state legibility, and a failure to protect property rights and deliver basic services to citizens. Technology is often viewed as a panacea for the problem of low state capacity. Government programmes have a concentrated focus on digitisation and have dedicated a large number of resources towards technology-based programmes and solutions to administration challenges. In this paper, we examine the current applications of technology in the field of land in India for administration and the delivery of citizen services. We examine what is working and what is not and question whether technology is leading to the desired outcomes. We explore path-breaking innovations in the field that might be applied in India and propose the first-principles framework for evaluating the application of technology in the field of land administration in India. |

| Abstract: | Biodiversity offsets (BOs) are increasingly used as economic instruments to manage biodiversity and ecosystem services in the context of economic development. This study investigates the sustainability conditions of BOs. It focuses especially on both the timing and pricing of BOs in development‐offset projects. To address this issue, a minimal time control model is proposed, allowing a dynamic and multicriteria approach to be combined through both ecological and economic targets. We rely here on no net loss (NNL) and positive net present value (NPV) goals. In particular, we focus on an offset marginal price, called offset sustainability price (OSP), which equalizes the NNL and payback times. We prove analytically how this OSP pricing corresponds to a win–win solution in terms of ecological‐economic synergy. We also show that this OSP pricing can be very high compared to the project rate of return, particularly when the biodiversity loss is high. More globally, a static comparative analysis shows the extent to which the economic and biodiversity parameters impact the OSP. Finally, a numerical application related to mangroves and aquaculture in Madagascar illustrates the analytical findings. For this case study, we argue that the current BO price is underestimated. |

| Abstract: | The Wallon Water Company (SWDE) and the National Research Institute for Agriculture, Food and the Environment (INRAE) joined forces from 2020 to 2023 to carry out the applied research project entitled ‘multi-scale asset management of drinking water networks' (GePaME). This scientific program is based on a service-performance driven water infrastructure asset management, mainly in terms of preservation of drinking water resources (control of water losses), continuity of service (control of network failures), quality of water, and service pressure. It adopts a multi-scale approach, which considers service performance from the local level (pipe segment) to the territorial level (District Metered Area (DMA), entire system) and from the short term (annual work programing) to the long term (investment strategy for the next decades). This requires being able to assess user vulnerabilities and knowing what elements of the network environment are affected by poor service performance. Furthermore, the methods and tools developed must take into account the operational organization and governance of the SWDE. |
| Abstract: | La Société Wallonne des Eaux (SWDE) et l'Institut National de Recherche pour l'Agriculture, l'Alimentation et l'Environnement (INRAE) se sont associés de 2020 à 2023 pour réaliser le projet de recherche appliquée intitulé « Gestion patrimoniale multi-échelle des réseaux d'eau potable » (GePaME) . Ce programme scientifique s'appuie sur une gestion du patrimoine des infrastructures d'eau axée sur la performance des services, principalement en termes de préservation des ressources en eau potable (maîtrise des pertes en eau), de continuité de service (maîtrise des pannes des réseaux), de qualité de l'eau et de pression de service. Il adopte une approche multi-échelle, qui considère la performance du service depuis le niveau local (segment de canalisation) jusqu'au niveau territorial (secteur hydraulique, système complet) et du court terme (programmation annuelle des travaux) au long terme ( stratégie d'investissement pour les prochaines décennies). Cela nécessite d'être capable d'évaluer les vulnérabilités des utilisateurs et de savoir quels éléments de l'environnement réseau sont affectés par de mauvaises performances de service. Par ailleurs, les méthodes et outils développés doivent tenir compte de l'organisation opérationnelle et de la gouvernance de la SWDE. |

| Abstract: | The USDA, Economic Research Service’s (ERS) Food Expenditure Series (FES) is a comprehensive measure of the total value of food acquired in the United States over time. FES provides users with data to evaluate changes in food spending and its composition; however, FES is limited to the national level. This report presents the methodology and data used to generate food expenditure estimates at the State level. The State-level FES follows a similar methodology used in the national level but with a different underlying dataset and benchmarked to the national-level estimates. The national-level estimates are based primarily on food sales reported in the U.S. Department of Commerce, Bureau of the Census’ Economic Census, which is published every 5 years, and uses three annual surveys to interpolate between years and extrapolate lagged data forward. The State-level FES estimates are based primarily on sales reported in the National Establishment Time Series Database. The database provides time-series data at the establishment level across all sectors, including grocery stores and food service outlets. The State-level FES can be used by government agencies, academics, the public, and other stakeholders to understand differences in consumer food acquisitions and spending behavior at a more granular level. |

| Abstract: | Household scanner data are a rich resource for understanding food purchasing habits in the United States. The IRI Consumer Network provides a detailed account of the retail food purchases for a large, nationally representative sample. These data further include self-reported height and weight for a subset of households that complete the MedProfiler survey. Together, the Consumer Network and MedProfiler surveys provide a unique opportunity to study the relationship between diet and obesity. This report includes an assessment of the MedProfiler height and weight data in determining body mass index (BMI) for children and adults, using MedProfiler data from 2012 to 2018 and National Health and Nutrition Examination Survey data from 2011–2012 to 2017–2018. In addition, because self-reported height and weight may often be misreported in survey data, the report explores adjustment methods to account for any self-reporting measurement bias. Finally, since food-purchase data are collected at the household level, the report includes a comparison of methods for defining the obesity status of a household. |

| Abstract: | The pandemic generated heterogeneous demand shocks in the food away from home industry's consumption channels: on-site and deliveries/takeaways. Hence, price adjustments by consumption channel could have also been different. This study examines dishes' prices intended to be consumed as deliveries, which come from an online food ordering and delivery platform in Mexico City (CDMX); as well as those aimed at on-site consumption, which are considered in CDMX's CPI. I document that during part of the period between April 2020 and March 2022 delivery prices grew at a faster rate than those for on-site consumption. This is consistent with the idea of positive demand shocks for delivery prices and negative for on-site prices. By March 2022, their cumulative price growth across both consumption channels was similar. |

| Abstract: | Honey consumption in Russia has been actively growing in recent years due to the increasing interest in healthy and environment-friendly food products. However, it remains an open question which characteristics of honey are the most significant for consumers and, more importantly, from an economic point of view, for which of them consumers are willing to pay. The purpose of this study was to investigate the role of sensory characteristics in assessing consumers' willingness to pay for honey and to determine which properties and characteristics "natural" honey should have to encourage repeated purchases by target consumers. The study involved a behavioral experiment that included a pre-test questionnaire, blind tasting of honey samples, an in-room test to assess perceived quality, and a closed auction using the Becker-DeGroote-Marschak method. As the result, it was revealed that the correspondence of the expected sensations to the actual taste, taste intensity, duration of the aftertaste and the sensations of tickling in the throat had a positive effect on both the perceived quality of the product and the willingness to pay for it, while perception of off-flavors or added sugar had a negative impact. Using factor analysis, we have combined 21 sensory characteristics of honey into eight components that were sufficient to obtain the flavor portrait of honey by Russian consumers. |
