Abstract

Fish are a primary source of calories, macronutrients, and income for coastal communities around the world, but overfishing and environmental changes have dramatically reduced productivity in the majority of small-scale fisheries. The social costs of these losses are believed to be large, particularly in poorer communities, but most estimates of fishery productivity effects on households are contextual and difficult to generalize. We combine a remote sensing measure of pelagic fishery productivity with geolocated child health and growth data from 34 countries in the coastal tropics. We estimate that the difference between sustainedly good versus bad fishing conditions corresponds up to a 0.16 increase in WHO child weight measures. This strong coupling of child health to fishery productivity highlights the key role fisheries play in food security, implying a substantial increase in risk of wasting and undernourishment in our sample should coastal fisheries collapse.
