Water Recharge Zone and Community Participation in the Management of the Totorani Micro-Watershed

Sustainable water management in high Andean ecosystems involves identifying and protecting recharge areas, integrating both biophysical and social knowledge. The purpose of this study was to conduct a participatory analysis of the recharge zone in the Totorani micro-basin, with a total area of 61.39 km2, located in Puno District, Peru, which supplies water to more than 21,000 people. A hierarchical multicriteria analysis in a GIS environment was used, considering five variables (vegetation cover, slope, soil type, geology, and land use), complemented by participatory workshops. The results indicate that moderate recharge predominates in 56.01% of the area, followed by high (39.91%) and very high (3.81%) recharge, associated with the high-altitude Andean wetlands and alluvial plains. Areas of low recharge comprised 0.28% and were found on slopes >30%, with thin soils and low infiltration. The participatory validation process confirmed the alignment between the maps and local knowledge, emphasizing the wetlands and springs as essential areas for water regulation. The stakeholder analysis identified three key groups as direct users: farmers and livestock breeders, public or educational institutions, and social organizations. The stakeholders highlighted threats, such as agricultural expansion, overgrazing, and climate variability, while also emphasizing the importance of traditional conservation practices. Water recharge in Totorani is both a biophysical and social process, requiring the integration of technical methodologies with community participation for effective management. These findings represent a strategic contribution to water governance and offer a replicable model for other high Andean micro-basins.
