Associate Professor of Agricultural and Applied Economics, University of Missouri. Dr. Valdivia’s research and outreach activities concentrate on understanding the mechanisms that lead to sustainable livelihood strategies. All my activities require collaboration with several disciplines. Methodological approaches in her research are household economics, political economics, and sociology to study decision making in rural areas of the tropics, especially in semi-arid highland and sub-humid regions of Latin America and East Africa. The purpose is to understand the factors that enable individuals, households and communities in rural areas to transition to food security and economic growth in a sustainable matter, and to design technologies and policies to facilitate this process. She also studies the impact of climate, markets, technologies and policies at the community, household, and intra-household levels include gender, microeconomic and political economy approaches.
