My main research program focuses on impact evaluation of agricultural research on poverty, food security and nutrition, factors driving and constraining technological adoption, agricultural productivity, and policies affecting economic development and poverty reduction in developing countries. Recently I performed an ex-post impact evaluation of modern improved bean varieties among rural households in Rwanda and Uganda and assessed changes in poverty profiles in Zimbabwe.
Project title: Adoption and Diffusion of C88 Potato Variety in China: Spatial Variability of Productivity Gains and Cost Savings and Value Chain Development
Funding source: The International Potato Center (CIP) and CGIAR’s Standing Panel on Impact Assessment (SPIA)
Brief description: The purpose of this research project is to assess the adoption and impact of C88, a late-blight resistance potato variety released in China in 1996. C88 was adopted quickly because of its late-blight resistance property, which provides a yield advantage over other varieties, and demand in the growing potato industry. Impacts will be assessed at the farm and market level.
Project title: Estimating household demand for millet and sorghum in Niger and Nigeria using an Almost Ideal Demand System
Funding source: USAID in partnership with International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Brief description: While millet and sorghum are key to household diets in Niger and Nigeria, factors such as population growth, urbanization, and income increase are expected to shift consumer preferences, by for example moving consumption patterns away from starchy-based diets. In addition, preferences for cereals might shift away from millet and sorghum, towards rice and wheat. Therefore, there is a need to assess the importance of sorghum and millet relative to other cereals and food groups, e.g. meat, diary, and fruits and vegetables, in this changing environment. Therefore, the objectives of this study are to gain an understanding of the demand drivers for sorghum and millet and how these two crops respond to changes in food prices and income level.
Project title: Assessing impacts of adoption of high iron bean varieties and their impact on iron intakes and other livelihood outcomes in Rwanda.
Funding source: International Center for Tropical Agriculture (CIAT), HarvestPlus, and CGIAR’s SPIA
Brief description: Research project in Rwanda examining the household- and market-level impacts of iron-fortified bean varieties released in the country by Harvest Plus. Project involves collecting and analyzing a large household dataset. Econometric estimates of treatment effects from adoption of new technologies are combined with market-level models to account for impacts on farm operations, yields and farm income, and dietary diversity of poor producers.
Project title: Disaggregated analysis of bean consumption demand and contribution to household food security in Uganda and Tanzania
Funding source: CIAT
Brief description: The purpose of this research activity is to assess current and future bean consumption demand in Uganda and Tanzania. More precisely this study aims at establishing the role beans play in the dietary patterns of the poor, estimating the effect of increasing bean trade and production shocks on current and future bean consumption, and evaluating whether a decline in bean consumption presents a nutrition and food security risk to the poor.
