This document summarizes research on the environmental impacts of Index-Based Livestock Insurance (IBLI) in pastoral areas. The research uses GPS collars and surveys to track how pastoralists' livestock movement patterns change in the presence of IBLI. Preliminary findings show that IBLI leads to increased herd sizes and more concentrated, intensive livestock grazing near water points. However, larger studies are still needed to fully understand the environmental effects as IBLI programs scale up.
