La cuenca alta del río Acre

The upper Acre River basin, shared by Bolivia, Brazil, and Peru, faces increasing climate extremes, including more frequent floods and severe droughts, alongside significant deforestation. While regional frameworks like the Amazon Cooperation Treaty exist, the report finds a gap between high-level agreements and local implementation due to differing national legal frameworks and a lack of formal basin committees. The document analyzes recent governance efforts—such as Bolivia's Strategic Water Planning Strategy (EPHIC), Brazil's state-level management, and Peru's progress toward creating a Basin Water Resources Council—and recommends consolidating existing local platforms through voluntary coordination and shared data protocols rather than creating new formal structures.

• The upper Acre River basin is experiencing an increase in the frequency and intensity of extreme climate events, particularly since 2010, with floods being the most recurrent phenomenon.
• Deforestation in the basin has resulted in the loss of over 12% of forest cover over the last 25 years, driven by forest fires increasing since 2013 and land conversion for cattle ranching in the Brazilian municipalities of Brasileia and Epitaciolandia.
• There is a significant divergence in water governance models among the three countries: Bolivia uses a state-centric sectorial approach; Peru employs integrated basin management with ecosystem-linked payment mechanisms (MERESE); and Brazil utilizes a market-oriented approach with robust water-use charges and green finance.
• The MAP Initiative demonstrated that while voluntary community and academic cooperation can be valuable, such efforts lack sustainability without formal institutional backing and stable financing.
• Bolivia is implementing the Strategic Water Planning Strategy (EPHIC), which proposes a multi-actor institutional structure including a Governing Board and a Financial Instance using a trust fund to mix public, private, and international funding.
• Brazil has not yet institutionalized a specific Acre River basin committee, although the basin is subject to integrated management by the State Secretariat of Environment (SEMA) and the Environment Institute of Acre (IMAC).
• Peru is in the process of creating the Madre de Dios Interregional Basin Water Resources Council (CRHC), having already established a driving group and a work plan.
• The report recommends that transboundary cooperation should focus on synchronizing existing local governance platforms through voluntary agreements and real-time hydrological data sharing rather than creating new structures.
