This paper estimates the causal effect of renewable water conditions and water use on violent conflict in rural agrifood systems. We implement a fixed-effects instrumental variables strategy that uses plausibly exogenous temperature and precipitation shocks to instrument multiple water outcomes. Annual specifications are imprecise, but five-year aggregations yield sharper inference and show that higher renewable freshwater availability significantly reduces conflict risk. Water use margins are central: freshwater withdrawals are associated with lower conflict, whereas higher aggregate water-use efficiency is associated with increased conflict risk. Overall, the results indicate that climate-driven water shocks operate through distinct channels - stocks, withdrawals, and efficiency-and that empirical conclusions depend critically on time aggregation and the definition of water being instrumented. The findings imply that climate adaptation and water policy should be paired with conflict-sensitive governance and improved measurement of local water use and access.
