Rainwater harvesting (RWH), the practice of centralizing, collecting, and storing rainwater for later use, has the potential to help alleviate water stresses in rural and tribal communities in arid and semi-arid environments. In a paper and 6-part video series, Native Climate collaborator Brianda Hernandez Rosales explores the main components needed to determine the feasibility of rainwater harvesting in arid and semi-arid environments.
