According to the World Bank and the World Health Organization, Bolivia is one of the poorest and most unequal countries in the western hemisphere. The fertile Andean valleys have the potential to produce increased fresh vegetable yields. Unfortunately, farmers in this region lack the infrastructure necessary to capture and store water during the rainy season for irrigation during the dry season. Without irrigation, farmers continually fail to meet the nutritional and economic needs of their communities. The irrigation pond projects initiated by Mano a Mano and community members from Omereque present an opportunity to increase the economic and nutritional well-being of farmers and their households. We worked with Mano a Mano in Bolivia last summer to develop and implement an evaluation of the project. However, once in the field, we encountered a number of obstacles to performing a rigorous and comprehensive evaluation. The objective of our presentation will be to consider the methodological challenges we faced, as well as stimulate discussion on evaluation strategies in resource-limited environments.
