This thesis analyzes the process and effects of a Research for Development project in Rakai, Uganda, using data collected during a research stay in the field during the summer of 2013. In the course of the WATERCAP project, agricultural trainings were conducted with farmer groups in order to achieve enhanced water management among the farmers. For this purpose, rainwater harvesting tanks were built on selected farmers’ properties. The aim of the author’s research was to compare the project’s conceptualization of processes and effects with her own observations as well as with the perceptions of the farmers and project staff. For this purpose, qualitative interviews with the project’s stakeholders were conducted. This allowed for a comparison of actors’ views and made it possible to understand values underlying stakeholders’ actions. It was assessed if processes took place in a participatory manner and how the project impacted water management practices within the farmer groups. The epistemological interest was to develop an understanding of the complexity and change mechanisms that determine project processes and effects.
