Social norms, tenure security and soil conservation: Evidence from Burundi

We use a new dataset from war‐torn Burundi to explore how various institutional proxies affect investments in soil conservation. We ‘unbundle’ institutions and distinguish between various proxies for tenure security and social norms. While we find significant correlations between certain proxies for tenure and social norms on the one hand, and investments in erosion management on the other, this is not true for all proxies. Using local conflict measures as instruments for institutional quality, we find tentative evidence of a causal effect of tenure security on erosion management, but not on investments improving short‐term soil fertility.
