Supermarkets, specialized wholesalers, and processors and agro-exporters' agricultural value chains have begun to transform the marketing channels into which smallholder farmers sell produce in low-income economies. We develop a conceptual framework through which to study contracting between...

Supermarkets, specialized wholesalers, processors, and agro-exporters are transforming the marketing channels into which smallholder farmers sell produce in low-income economies. We develop a conceptual framework with which to study contracting between smallholders and a commodity-processing...

The prevailing definition of food security, agreed upon at the 1996 World Food Summit, is "a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active...

Food security is inherently unobservable and difficult to define, but both intrinsically and instrumentally important. Humans have a physiological need for the nutrients supplied by food. Food is therefore a crucial input into performance and well-being. Many development programs, projects and...

This paper develops an integrated model of the food aid distribution chain, from donor appropriations through operational agency programming decisions to household consumption choices. We use this model to simulate alternative policies and to perform sensitivity analysis to establish how varying...

Discussions on food aid and dependency often draw on what appears to be a broad body of evidence, but closer inspection reveals that much of this does not in fact demonstrate a causal link between the two. This desk review has three objectives: (i) to identify the pathways through which negative...
