Plan Director de la Cuenca del Río Tupiza

The 'Plan Director de la Cuenca del Río Tupiza' (PDCRT) is an executive summary of a strategic planning instrument designed to guide the integrated and sustainable management of the Tupiza River basin in Potosí, Bolivia. Developed by the Stockholm Environment Institute (SEI) under the Bolivia WATCH program and in collaboration with the Ministry of Environment and Water, the plan updates a 2018 version to incorporate climate change projections, robust decision-making tools, and a stronger focus on sustainable sanitation. The PDCRT establishes eight strategic lines to address vulnerabilities in water access, gender equity, ecosystem preservation, sustainable production, environmental education, hydroclimatic risk management, sustainable mining, and inter-institutional governance, with a total estimated investment of BOB 160,472,859 over a five-year horizon.

• The Tupiza River basin covers 2,309 km², supports over 47,000 people (6% of Potosí's population), and serves as part of the headwaters for the Plata macro-basin.
• Climate projections for 2022-2050 under the RCP 8.5 scenario indicate significant risks. The CMCC-CM model predicts a 1.8°C increase in average temperature and a 35% reduction in average annual flow, while the IPSL-CM5A-LR model predicts a 1.8°C temperature increase, a 10% reduction in annual precipitation, and a 38% reduction in average annual flow.
• Water and sanitation services in the basin show high vulnerability. In 9 of 24 studied communities, less than 80% of the population has water services at a 'safely managed' or 'basic' level. Furthermore, in 20 of the evaluated communities, an average of 58% of inhabitants practice open defecation.
• Agricultural irrigation is severely limited by water availability. While the irrigable area is approximately 17,397 ha, current water sources only support an optimal irrigated area of 4,685 ha, which is 27% of the total irrigable area.
• Mining activities have caused widespread environmental degradation. The basin contains 54 mines or mining sites and 684 Mining Environmental Liabilities (PAM), including waste deposits and tailings. Special Transitional Authorizations (ATEs) cover approximately 841 km², representing 36% of the basin's area.
• The basin faces significant hydroclimatic risks, specifically severe flooding between 2016 and 2019 that damaged public and private infrastructure, including the Wastewater Treatment Plant (PTAR), which has remained partially inactive since then.
• Social and gender inequalities are evident in water management. Rural areas are more vulnerable, and the burden of water collection falls primarily on women, creating an opportunity cost that disadvantages families. There is a noted lack of women's participation in decision-making bodies such as the Inter-institutional Basin Management Platform.
• The PDCRT proposes a five-year implementation plan with a total investment of BOB 160,472,859. The highest costs are allocated to 'Safe water for homes, sanitation and hygiene' (BOB 64,107,226) and 'Sustainable production with efficient use of water for irrigation' (BOB 65,396,486).
