Climate change and the farmer-Pastoralist's violent conflict: Experimental evidence from Nigeria
通过尼日利亚冲突区550名居民的调查实验，发现当人们意识到气候变化是牧民迁移的主因时，更支持接纳牧民的政策，且该效应不受冲突经历或信任度影响。
We examine how a better understanding of how climate change induces herder migration to other locations and subsequent conflicts with sedentary farmers influences respondents' support for policies that accommodate outgroup members. We conducted a pre-registered survey experiment with 550 residents of a conflict zone in Nigeria and discovered that as perceived herder vulnerability due to climate change increases, residents are inclined to support policies that accommodate these herders. In other words, rhetorical exposure that leads respondents to perceive climate change as the primary driver of herder migration to other communities increases support for accommodating policies (i.e., policies that support integrating outgroup members into their community). The effects are essentially consistent regardless of the respondents' proximity to the conflict, as measured by their loss experiences or their trust in outgroup members or dominant domestic institutions. These results highlight the need to conceptualise vulnerability as the primary driver of the herder-farmer conflict, which is a settled fact as opposed to other 'conspiratorial' narratives, allowing for new methods of mapping public opinion in favor of integrating both groups for peaceful coexistence in conflict zones. • A key driver of clashes between Nigerian farmers and herders is climate-induced migration of herders seeking grazing sites. • Exposure to this perspective of the conflict shapes understanding of a key cause of the herders-farmers crisis in Nigeria. • Treatment exposure causes farmers to support policies that integrate herders into their community for peaceful co-existence. • This finding holds despite respondents' conflict exposure or their trust in outgroup members or key domestic institutions.
