RÍOS DEL PÁRAMO AL VALLE, POR URBES Y CAMPIÑAS

The report details a USAID-funded project led by the Stockholm Environment Institute to integrate climate change considerations into Colombian water management. By deploying the WEAP modeling system and a participatory RDS process in the Otún, La Vieja, and Alto Magdalena watersheds, the program built technical capacity within regional environmental authorities (CARs) and academic institutions. Key findings include the critical role of páramo ecosystems in maintaining dry-season baseflows and the potential for hydropower development to disrupt downstream wetland dynamics in the Magdalena-Cauca basin. The project emphasizes moving from 'conscious incompetence' to 'conscious competence' in climate adaptation planning through institutional capacity building and the creation of a professional community of practice.

• The program successfully implemented a Robust Decision Support (RDS) process to help Colombian regional environmental authorities (CARs) and academic institutions prioritize adaptation alternatives to reduce climate vulnerability.
• In the Otún watershed, páramo ecosystems are vital for water security, contributing approximately 40% of total streamflow and up to 80% of total flows during the low-flow month of September in critical dry years.
• For the Otún watershed, a regulatory adaptation strategy prioritizing water allocation as 1st to environment, 2nd to water consumption, and 3rd to energy is recommended to maintain e-flow and urban water coverage.
• In the La Vieja watershed, the combination of municipal wastewater treatment plants and improved wastewater management in the coffee sector is the most effective strategy for reducing DBO5 levels.
• Vulnerability analysis in the La Vieja watershed identified that the municipalities of Armenia, Circasia, La Tebaida, and Salento face the highest vulnerability regarding water supply constraints.
• In the Alto Magdalena region, the project supported the development of the Huila 2050 Climate Action Plan and demonstrated that WEAP can be used to automate the estimation of Regional Water Study (ERA) indicators.
• Analysis of the Magdalena-Cauca basin indicates that expanding upstream hydropower storage to 30% of average annual runoff would substantially reduce seasonal river-floodplain interactions and eliminate low-flows during dry months, potentially harming wetland ecosystems.
• The project found that while hydropower dams might be proposed to reduce flood risks, they would not protect lowland communities from extreme floods because reservoirs must release water for dam safety during high flow events.
• The program highlighted a systemic gap in Colombian water governance where national guidance documents for mandated plans (such as POMCA and PORH) lack explicit requirements to consider climate change.
• Capacity building was most effective when engaging young professionals and legacy academic institutions, though the project noted that CARs' engagement requires stronger management commitment to devote personnel time.
