Global exports draining local water resources: Land concentration, food exports and water grabbing in the Ica Valley (Peru)

The agro-export boom is threatening the sustainability of water resources in many regions around the world. This\r\nis the case of the Ica valley in Peru, where in the last decades traditional agriculture has been replaced by big agricultural businesses to meet the growing international food demand. This has led to increasing land concentration by large exporting farms jointly with an increase in groundwater exploitation for irrigation. In this\r\npaper, we analyze the effect of land concentration, exporting crop specialization and irrigation intensity on groundwater sustainability using an econometric approach. Our findings highlighted an inverse relation between groundwater sustainability in terms of water withdrawal in the Ica Valley and the intensity of irrigation (drip\r\ntechnology), commodity specialization and concentration of large farms. More research is needed to fully understand the impacts of this very important economic activity on Peru’s natural resources, to ensure its sustainability in the long term.
