Are residents of developing countries willing to support economic development despite environmental damage and conflict risks? To examine this question, we conducted a survey experiment in Turkana County, home to an economically and politically marginalised pastoral community in Kenya but newly impacted by a large-scale infrastructure development project, namely, the Lamu Port–South Sudan–Ethiopia Transport (LAPSSET) corridor project, which will generate economic development at the expense of significant environmental degradation and intensified conflict risks. We found that the majority of our respondents in Turkana support LAPSSET regardless of the expected environmental damages and conflict risks. Although concerns about unequal distribution of economic opportunities and cross-border ethnic conflicts decreased support for LAPSSET, the decreases in support were substantively small and only found conditionally based on certain sub-groups. Our results align with earlier literature findings that residents of developing countries are willing to tolerate negative consequences while prioritising economic development.
