In vulnerable water basins, unregulated access to solar energy and groundwater can threaten water security through increased abstractions. Public and development agencies are therefore exploring options to provide farmers with additional income from solar farming while protecting groundwater resources. Solar energy farming is combined with attractive purchase guarantees in order to encourage farmers to efficiently use solar energy on-farm and sell the energy excess. This article evaluates a project from the Azraq Basin in Jordan, and presents similar international experiences, particularly from India. It assesses solar energy farming as an innovation from a water-energy-food nexus perspective.
