ESAPP was a research implementation programme that sought to advance sustainable development through joint action and co-production of knowledge in the context of local and regional initiatives. It promoted sustainable land management and equity-oriented sustainable regional development in Eastern and Southern Africa, particularly Eritrea, Ethiopia, Kenya, Tanzania, Mozambique, and Madagascar. It was funded by the Swiss Agency for Development and Cooperation (SDC), coordinated by the University of Bern’s Centre for Development and Environment (CDE), and implemented by CDE and a network of partner institutions in Eastern and Southern Africa. Launched in 1999, the programme concluded in 2015. More than 300 demand-driven smallgrant projects were carried out in that time, with careful efforts to systematically integrate, link, and build on the results of every project. Independent experts evaluated the programme on four occasions, highlighting the success of the approach each time.
