Managing waterways for ecosystems with minimal loss to existing water uses is increasingly difficult. As we’ve discussed in the first two blogs in this series (here and here, now with Spanish language translations), California and Chile both struggle with this challenge. Both are mostly dry regions with deep economic and human dependence on water and very disrupted and vulnerable native ecosystems. Both also face the dual challenges of droughts and floods. For the last year, an international collaboration on environmental flows between Chile’s Universidad del Desarrollo (UDD) and Universidad de Talca, and the University of California, Davis (UCD) focused on these common issues to draw lessons from California’s experience. … The project supports further investigation of a functional flows approach for Chilean watersheds, implemented through a collaborative portfolio of water management instruments. This blog summarizes the findings of the research group.
