Proposed hydropower dams at more than 350 sites throughout the Amazon require strategic evaluation of trade-offs between numerous ecosystem services provided by Earth's largest and most biodiverse river basin. These are spatially variable, hence collective impacts newly built depend strongly on their configuration. We use multiobjective optimization to identify portfolios that simultaneously minimize flow, connectivity, sediment transport, fish diversity, greenhouse gas emissions while achieving energy production goals. find uncoordinated, dam-by-dam expansion has resulted in forgone service benefits. Minimizing further damage from development requires considering diverse environmental across entire basin, as well cooperation among Amazonian nations. Our findings offer a transferable model for transboundary basins.

Linkages between flow regime, biota, and ecosystem processes: Implications for river restoration DOI Open Access

Published: Sept. 19, 2019

River ecosystems are highly biodiverse, influence global biogeochemical cycles, and provide valued services. However, humans increasingly degrading fluvial by altering their streamflows. Effective river restoration requires advancing our mechanistic understanding of how flow regimes affect biota ecosystem processes. Here, we review emerging advances in hydroecology relevant to this goal. Spatiotemporal variation exerts direct indirect control on the composition, structure, dynamics communities at local regional scales. Streamflows also processes, such as nutrient uptake transformation, organic matter processing, metabolism. We deepening biological not just static patterns, affected stream research nexus flow-biota-ecosystem processes is an early stage. illustrate frontier with evidence from altered regulated rivers urban streams. identify challenges that should be prioritized advance process-based restoration.

Abstract The natural flow regime concept has contributed significantly to environmental flows (e‐flows) science and applications over the last 20 years. Natural regimes reflect long‐term, historical patterns of variability that have shaped riverine species’ adaptations continue shape community ecosystem structure function. This scientific perspective, however, carries with it important assumptions about climatic ecological stationarity in terms “reference” conditions provide a basis for comparing success or outcomes e‐flow interventions. Non‐stationarity climate other (temperature, sediment, nutrients) features (non‐native species spread) presents challenges science. Reliance on assumption restoration reference either hydrologic is no longer tenable, an expanded e‐flows foundation needed meet several facing future implementations. Currently recognised limitations contribute emergence research frontiers need further development. These are (1) shifting from static, regime‐based metrics dynamic, time‐varying characterisations; (2) expanding (and space–time scales) used primary reliance states include process (population) rates traits; (3) incorporating “non‐flow” (e.g. temperature, sediment) guide prioritisation likelihood success; (4) broadening incorporate more theory will predictive perspective managing remain understand response alterations inform management.
