The 'Citizen Participation in Adaptation to Climate Change' (CPACC) project aimed to build the resilience of farming households to climate shocks, through promoting conservation farming techniques and livelihood diversification, and through supporting disaster-planning activities and early-warning systems at the community level. This Effectiveness Review used a quasi-experimental approach to assess the impact of the project among households whose members directly participated in the project activities, in one of the three districts where the project was carried out. The results provide evidence that the project had a positive effect on the resilience of participant households, particularly through the community-level disaster preparedness activities. There is also evidence that the project had a positive impact on the adoption of conservation farming techniques, on the area of land cultivated, and on yields. However, the project does not appear to have had the positive effects it sought on engagement in non-agricultural income-generating activities, nor on participation in savings groups. There is no indication that the project had had a positive impact on households' overall material welfare by the time of the survey. This report is part of Oxfam's Effectiveness Review Series.
