The 'Building Resilience in the Arid and Semi-Arid Lands of Northern Kenya' project was implemented in Turkana County, in Northern Kenya, between July 2012 and April 2015. The project was designed to build the resilience of project participants to a number of shocks and stresses: droughts - which threaten the area annually - floods and outbreaks of human and animal diseases on the one hand, and anthropocentric risks on the other hand, such as fire, livestock theft, and conflicts. The project worked at different levels to try and reduce households' vulnerability to these risks, through Community-Managed Disaster Risk Reduction (CMDRR) and integration of community-level plans and committees into the work of the county government. This Effectiveness Review used a quasi-experimental evaluation design to assess the impact of the project activities, at the household- and community-level. The results provide evidence that the project had had a positive impact on households' resilience capacities. This report is part of Oxfam's Effectiveness Review series.
