Galápagos is a living laboratory where every environmental decision matters. On Santa Cruz, the most populated island of the archipelago, freshwater is a limited and increasingly vulnerable resource due to urban growth, agricultural pressure, saltwater intrusion, and climate change. In this context, understanding how water behaves across the landscape becomes essential for water security.

Our study proposes a geomorphological approach to identify which watersheds offer the best conditions for water conservation, which require immediate intervention due to their susceptibility to erosion, and which could be suitable for sustainable agricultural activities.
