- Master Thesis 
We are evaluating an aid project in the southern parts of Tanzania called the Food Value Chain Development Project. The project objective is to help farmers increase the quality and quantity of their produce to able the farmers to sell their produce to a high-end market. To able framers to meet the high-end market demands, the project aims to organize groups of farmers into businesses. Our research questions are based on these producer businesses (PB), what extent functioning PB has been established, what extent these PB have been connected to high-end markets and if these activities have resulted in higher income among the farmers. During the implementation of the project the pigeon peas market collapsed, this collapse impacted many of the farmers involved in the project. We therefore have a research question about the extent the project participation helped the farmers adapt to the collapse. To answer these research questions, we travelled down to the project area and conducted qualitative interviews in three of the eight districts who has been part of the project. In our evaluation, we have used Howard White’s theory-based impact evaluation approach to give a better understanding of why interventions have succeeded or not. The results of our study have been mixed. There are some PBs who have been well established and are functioning well, while other PBs are barely operating. Only three of the PBs have been able to reach high-end markets and only half of the PBs we talked to have sold after they became part of the project. The project has in other words not been able to connect most of the PBs to high- end markets. 24 of 50 farmers we interviewed said their income had increased as a result of training and/or sales to better paying markets. The farmers adapted variously to the pigeon peas collapse based on how dependent they were on pigeon peas. Only a few of the farmers we interviewed said that their participation in the project helped them adapt to the collapse.
