摘要

Domestic violence (DV)–patterns of physical, sexual, economic, or psychological abuse by intimate partners and family members–persists as a serious national issue in Brazil despite public efforts to eliminate it. While the risk factors for and consequences of such violence are well studied, less is known about the potential impacts of global climate change on patterns of DV. Extreme weather (periods of extreme heat and prolonged drought) may impact patterns of DV through changing stress levels and agricultural household incomes. We test for such a relationship using administrative data from hospital reports, hotline calls, and female homicides, alongside weather and land use data. Our findings reveal a statistically significant, positive effect of higher daily maximum temperatures on violence but less evidence for a short- or long-run impact of rainfall. The results are consistent across different outcome variables and levels of aggregation, suggesting that climate change may exacerbate the risk of heat stress-related DV. Public policy should consider potential protective measures to insulate vulnerable households against extreme heat-related violence and consider the costs of interpersonal violence in analysis of climate change impacts.
