Within the search for reliable evidence on programs and policies that work to strengthen resilience among pastoral groups in the Horn of Africa, the potential contributions of peacebuilding have not been widely considered or studied. To help fill this knowledge gap, Mercy Corps recently undertook research into the links between conflict and drought resilience within the context of its programs in Southern Ethiopia. The study provides strong evidence of the contributions of peacebuilding programming to pastoralists’ abilities to productively cope with and adapt to the recent drought. The findings showed that the improvements to freedom of movement and access to water, pasture, and other natural resources brought about by Mercy Corps programs were key contributing factors to households’ drought resilience. The results lend validity to the broad theory of change examined by the study: Pastoralists in areas that have seen increased peace and security are more likely to have opportunities to employ effective livelihoods coping strategies, thus reducing their vulnerability to and aiding their recovery from extreme droughts.
