This study summarizes the concept of the food-energy-water security nexus (FEW nexus). The aim is to create awareness about the importance of the nexus and to enable stakeholders to consider interconnections between the sectors in their work. The FEW nexus is discussed in the context of Africa south of the Sahara (SSA)—using Malawi and Mozambique as case studies. Even though analyzing food, energy, and water security issues simultaneously is critical given the interconnections, summarizing interventions with the FEW nexus approach in Malawi and Mozambique, we found that there are only a limited number of interventions in place. Additionally, this study reviews macro- and microeconomic models that are able to analyze the FEW nexus. On the macrolevel, especially general equilibrium models are discussed, because they show trade-offs and synergies of nexus interventions at all economic levels. These models can help guide policymakers’ understanding of nexus effects ex ante and convince them to think beyond their respective political departments. On the microlevel, the impact of nexus interventions can be assessed with qualitative and quantitative approaches. There are specific challenges for nexus interventions when it comes to aggregation and planning of the targeting. A secondary data analysis of nexus interventions shows that existing data is not sufficient to conduct research specifically related to the FEW nexus. The results of this study will help research programs to reflect the key questions required to enhance adoption of FEW technologies and inform policymakers as they formulate policies that will exploit the strong synergies of food security, energy, and water investments.

Referrals between paraprofessionals and veterinarians are seen as a solution for improving disease surveillance, detection, and reporting as well as ensuring prudent use of antimicrobial agents in animals. This paper used data collected from paraprofessionals in Kenya and Uganda to identify factors influencing referrals to veterinarians by paraprofessionals using a probit regression model. The results show that the determinants of paraprofessional referrals to veterinarians include the following: paraprofessionals mobile phone ownership, gender, and training, as well as attendance of short term trainings, annual assessments, and membership in paraprofessional associations. The paper argues that legislation or supervision of paraprofessionals as well as expansion of mobile phone ownership by paraprofessionals, supporting the formation of paraprofessional associations, and investing in short term training are important factors for strengthening referrals from paraprofessionals to veterinarians.

In the mountainous regions of Southeast Asia, smallholder farmers are both victims of and actors in the degradation of natural resources, as a result of their agricultural activities. Addressing sustainable development thus requires a good understanding of the agriculture-poverty-environment nexus – defined as the set of complex linkages between agriculture, poverty and the environment – and of the economic incentives that drive the natural resource use of smallholder farmers in vulnerable areas. The objective of this chapter is to improve our understanding of the extent and nature of these linkages across different settings in Southeast Asia – namely northern Vietnam and northern Thailand, and to derive policy recommendations that can contribute towards the enhancement of sustainable development in these regions. The chapter draws on empirical research conducted in northern Vietnam and northern Thailand between 2007 and 2011.

A purchasing experiment in which genetically modified and conventional fries were offered for sale at mobile fast food stands in Germany was conducted to identify factors influencing the willingness of consumers to purchase genetically modified fries. In total, 331 purchasing decisions were made: 56.5% decided to purchase conventional fries, 22.4% genetically modified fries, and 21.1% no preference. A logistic regression model analyzing questionnaires found that worry about pesticides, frequency of organic food purchases, the acceptability of genetically modified foods with environmental benefits, and perceptions of health risks from genetically modified foods significantly impact the willingness to purchase genetically modified fries.

Sustainable development requires a mix of policies that can simultaneously address social, economic and environmental objectives. While the preceding chapters of this book have focused on agricultural, environmental and socio-economic aspects and related policies, this chapter looks at the commercialization of smallholder agriculture and, in particular, the need to target the poor so as to enable them to better participate in market-oriented development. The mountainous regions of northern Thailand and northern Vietnam have witnessed a substantial transformation over the last two decades, turning as they have from largely subsistence-oriented to market-oriented agriculture. This development began in Thailand earlier than in Vietnam, but during the 2000s, smallholder agriculture in Vietnam also commercialized at a rapid rate, leading to an increase in farm incomes and a decline in poverty levels. Our main policy conclusion here is that the commercialization of agriculture can be conducive to a sustainable increase in smallholder incomes and reduction of poverty levels; however, policies aimed at addressing the environmental externalities caused by market participation must be combined with socially-oriented policies that target poorer segments of the population, especially in the areas of education, health, social assistance, political participation and non-subsidized credit, as well as infrastructure and market-oriented development policies aimed at long-run sustainability.

Abstract Fake or substandard fertiliser is a growing concern in many countries. Even in places not affected by fertiliser quality problems, uncertainty could arise due to weather variability, soil quality, or doubts about the effectiveness of fertiliser in general. Past literature has shown that risk aversion leads to lower fertiliser use and farmers become less risk averse as they become wealthier. We build upon this literature by showing that the marginal effect itself might not be the same for farmers of different wealth levels either. In our study, the measures of risk aversion were elicited from two different techniques: a self-assessment question and a lottery game. Results from regression analysis show that the marginal effect of risk aversion on fertiliser use depends on the wealth levels of farmers. Low-wealth farmers reduce their fertiliser intensity when their risk aversion increases. The marginal effect for high-wealth farmers is insignificant.
