Recently, discussion had reemerged over the value of integrated pest and crop management training, through intensive approaches such as farmer field schools or participatory training, as a development approach (Feder et al, 2004). This paper develops a model of human capital accumulation through...

This paper examines the impact of participatory research and tests hypotheses on its effectiveness to increase the adoption of soil conservation and fertility management innovations in Southeast Asia. Participatory research activities are significant and positive in explaining the differential...

This study evaluates managerial differences between men and women and assesses the degree of bias introduced by omission of gender-influenced variables and ignoring the endogeneity of farmer characteristics and input levels. The results also give insight to improving research methods for...

This paper presents six key issues from the Rethinking Impact: Understanding the complexity of poverty and change Workshop (RIW) held in Cali, Colombia, March 26–28, 2008. The workshop discussed how agricultural and natural-resources research can be more effective in generating solutions for...

Through a survey of scientists from the International Maize and Wheat Improvement Center (CIMMYT) in 2004, this study assessed the extent to which participatory methods had been used by the center, how they were perceived by the scientists, and how participatory research could be applied more...

This study links intertemporal optimization to a biophysical crop growth model finding that agricultural intensification does not dramatically degrade soils in southern Mali. Productivity growth can be sustained through adoption of new techniques, particularly with policy reforms to reduce...

This paper presents a dynamic model of land resource degradation and shifting rice cultivation in West Africa based upon Boserup and Dvorak. The model indicates the ex ante impact of research strategies to maximize the economic benefits of host plant resistance and land resource management and...

Recent federal agricultural programs have accelerated the devolution of enterprise risk management responsibility from the state to individual producers. Using a biophysical simulation model, the risk management benefits of federal crop insurance and supplemental irrigation are derived and...

The purpose of this research is to determine how technically efficient small-scale producers are in two provinces (North and South Kivu) in the Democratic of Republic (DR) of Congo at producing two different varieties of beans: bush and climbing beans. In addition to calculating the efficiency...
