Mejorar la gobernanza de la llanura inundable en cuencas fluviales sobreconstruidas
Summary
This project brief describes research conducted by the Inter-American Institute for Global Change Research (IAI) on improving floodplain governance in over-built river basins, specifically focusing on the Paraná River downstream of the Porto Primavera dam in Brazil. The study aims to balance hydroelectric power generation with the maintenance of aquatic ecosystems and the socio-economic activities that depend on them.
Key insights
- The research identifies that several key socio-economic activities, including professional fishing, tourism, and recreation, are directly or indirectly dependent on fish and their ecosystems. These activities are currently hindered by conflicts of interest and difficulties in determining the relative importance of each activity.
- Using the Indicators of Hydrologic Alteration (IHA) method, scientists determined that fish reproduction and migration are strongly influenced by four specific flow components: the duration of flood events, the start date, the peak, and the frequency.
- The project developed a methodological framework to analyze how the abundance of migratory fish young-of-the-year (YoY) responds to different flow regimes. The findings suggest that satisfactory fish abundance can be achieved by focusing on key flow regime indicators and that multiple solutions for ecosystem recovery may exist through the rearrangement of these indicators.
- Researchers utilized Stochastic Dual Dynamic Programming (SDDP) to model the technical operations of 53 hydropower plants on the Paraná River. This model is being combined with a multi-objective evolutionary algorithm (MOEA) to analyze trade-offs between hydroelectric generation demands and ecosystem services to inform future reservoir operating policies.
