The Climate-Resilient Cities in Latin America Initiative (CRC) focused on small and medium-sized cities (50,000 to 1 million inhabitants) to bridge the gap between research and concrete climate action. The initiative emphasizes that while these cities are highly vulnerable to hydro-meteorological disasters, they offer significant opportunities for resilience due to their proximity scale. Key strategies included the co-generation of knowledge using both scientific data and citizen perceptions, the implementation of low-cost technological prototypes, and the integration of a gender perspective to address the disproportionate impacts of climate change on women. The report argues for a localization agenda where resilience is integrated into local development plans and supported by greater fiscal and administrative decentralization.

The document analyzes the critical link between forest cover and water security in the Cumbaza River micro-basin, noting that 85% of the area is degraded. It highlights how deforestation and climate variability increase sediment loads, affecting urban water treatment for 40,000 users in Tarapoto and reducing water availability for rice and aquaculture farmers. The brief recommends restoring 3,000 hectares in the upper basin by 2040 and 1,500 hectares in the Ahuashiyacu and Shilcayo sub-basins by 2050, while strengthening inter-institutional governance through the Cumbaza Micro-basin Management Committee.

The document applies a Water-Energy-Food (WEF) nexus approach to analyze the Cumbaza watershed in Peru, highlighting how deforestation and climate change threaten urban and rural resource security. It quantifies 11 key WEF interactions and projects resource demands through 2050, emphasizing the critical role of forest ecosystem services in maintaining water quality and quantity for the region's growing population.
