Modelación estratégica de la cuenca del río rocha

This research paper details the use of Robust Decision Support (RDS) and WEAP modeling to manage water resources in the Rocha River basin, Bolivia. It highlights critical vulnerabilities including unsustainable groundwater extraction, severe river pollution (BOD 428-852 mg/l), and projected water supply reductions of up to 13% due to climate change. The study concludes that no single strategy is sufficient; instead, a combination of the Misicuni project, new water transfers, wastewater treatment plants, and a reduction in agricultural water losses (currently averaging 70%) is required to ensure water security through 2050.

• The study identifies four primary uncertainties affecting the Rocha River basin: climate change, population growth, the reduction of agricultural areas, and changes in per capita water allocation.
• Climate change scenarios for the 2020-2050 period suggest that annual precipitation in the basin could decrease by up to 7%, with more severe reductions of 15% in February and 30% in March. Temperatures are projected to increase by up to 1.8 °C, potentially reducing water supply by 13% annually and up to 48% in March.
• The Rocha River suffers from severe water quality issues due to untreated wastewater discharges from the metropolitan area and industrial runoff. Biochemical Oxygen Demand (BOD) concentrations were found to fluctuate between 428 and 852 mg/l, exceeding permissible limits, particularly in the municipalities of Cochabamba and Sipe Sipe.
