The lack of updated information about food security is of concern to many countries, especially during and after economic crises, natural disasters, and conflicts. In this paper we present an analytical framework for assessing the effects of such crises on food security. This methodology can...

Coffee is the most important export crop in Uganda and an important source of income among smallholder farmers in large parts of the country. The Robusta type dominates coffee production and Ugandan Robusta is demanded by roasters as a component in certain blends due to its special taste...

"Because the conditions for agricultural development vary considerably across space, we need to develop methods that allow us to take such variability into account when evaluating development strategies for particular crops or farming systems. This paper addresses spatially varying...

This paper looks at differences in spatial and temporal variation of rice yields in China and Brazil. We find that rice yields in China have converged over time and that rice production has become more and more homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily...

"In this paper, the authors analyze the potential economic impacts of avian influenza (AI) in West Africa, taking Nigeria as an example. They find that, depending on the size of the affected areas, the direct impact of the spread of AI along the two major migratory bird flyways would be the loss...

"The Ugandan coffee industry is facing some serious challenges, including low international prices in the international coffee market, aging coffee trees and declining productivity, and, more recently, the appearance of coffee-wilt disease, which have all contributed to the decline in both the...

"Agriculture plays a dominant role in nearly all the countries of East and Central Africa, and many face similar agroecological, climatic, and development challenges. As a result, significant scale economies can be made through the regionalization of research and development (R&D) using networks...

"This paper examines differences in the spatial and temporal variations of rice yields in China and Brazil. Our analysis indicates that, in China, rice yields have converged over time and rice production has become increasingly homogeneous. In contrast, rice yields in Brazil have diverged over...

We analyse the potential economic impacts of avian influenza (AI) in Nigeria, using a spatial equilibrium simulation model. Depending on the size of the affected areas, the direct impact of the spread of AI along the two major migratory bird flyways would be a loss of about 4% of national...
