The present report sets out the findings of a cost benefit analysis conducted in northern Kenya in early 2016. This analysis examined seven resilience interventions delivered under DFID’s Arid Lands Support Programme (ASP) between 2013 and 2016. These interventions are being implemented by seven INGOs in four counties of northern Kenya, namely Mandera, Marsabit, Turkana and Wajir. The INGOs whose work was examined are BOMA, CONCERN, Oxfam, Save the Children, Solidarites, Trocaire and World Vision. This study was conducted using the “community-based cost benefit analysis (CBCBA)” methodology, which can be used to inform decision making about development investments and programming.
