Does drought reduce economic activity?
This paper examines the global effects of droughts on economic activity, proxied by remote-sensed nighttime lights data. We use two different, comprehensive indices of drought severity, one remote-sensed and one constructed from ground-sensed meteorological data, contributing to a literature on climate extremes that has previously focused on precipitation, rather than drought. Results suggest that moderate-or-worse droughts in the current year reduce luminosity by about 1 percent, with smaller but statistically significant impacts under even mild and incipient drought conditions. We estimate some lagged effects as well; moderate-or-worse droughts may reduce lights up to four years after they occur. We also test for mediating effects of access to groundwater resources of varying quality and access to reservoirs impounded by dams. We find evidence consistent with both groundwater and dams mitigating droughts’ economic impacts, though some of these results are not fully robust to the choice of drought index.
