The document describes a methodological effort to integrate Robust Decision Support (RDS) into Bolivia's National Watershed Policy, specifically for the Rocha River Basin Master Plan. It aims to provide stakeholders with tools to analyze interactions between water management interventions, manage hydrologic risks, and mitigate conflicts across different sectors and regions in the face of climate-induced water scarcity.

The report details the development of a water management strategy for the Rocha River basin, supported by the Ministry of Environment and Water (MMAyA) and the Autonomous Departmental Government of Cochabamba (GADC). It focuses on strategic modeling via the Water Evaluation And Planning (WEAP) system to address water vulnerability caused by limited resources, economic development needs, and climate change. The process emphasizes local participation and self-management to improve integrated water resources management.

The document evaluates the water security of the Rocha River basin, identifying critical deficits in urban and agricultural supply and poor water quality. Using the Water Evaluation And Planning (WEAP) system, it tests several strategies—including the Misicuni Multiple Project, new water transfers, wastewater treatment, and irrigation efficiency—finding that only integrated, combined strategies can guarantee water supply through 2050.

The Master Plan for the Rocha River Basin addresses critical water scarcity, pollution, and ecosystem degradation in the Cochabamba Department of Bolivia. It outlines five strategic lines—water management, sustainable basin management, institutional strengthening, knowledge management, and water culture—to improve water security and resilience. Key goals by 2040 include increasing safe water access to 834,049 people and reducing the total water deficit by 227 hm3, while mitigating risks from climate-induced precipitation changes and temperature increases.
