Description de la ressource pédagogique

Description (résumé)

The science and practical applications of environmental flows (e-flows) have advanced rapidly since the early 1980s. E-flows serve as a means to protect the flow regimes and ecosystems of undeveloped rivers, and conversely, as a means to restore the flow regimes and ecological health of regulated rivers. From simple beginnings in the form of ‘minimum flows’ to ensure adequate aquatic habitat for fish, the e-flows concept has expanded to embrace the water requirements of rivers and other aquatic habitats as ecosystems. “Holistic” ecosystem methods aim to devise a flow regime that will maintain habitat, dispersal and reproductive requirements of multiple taxa, and ecological processes, from river reach to basin scale, and more recently, to multiple basins at regional scale (e.g. the ELOHA framework). The presentation will describe recent efforts to promote e-flows for rivers as vital to human livelihoods and well-being, globally. I will briefly describe ‘The Brisbane Declaration and Global Action Agenda on Environmental Flows (2018)’ [https://doi.org/10.3389/fenvs.2018.00045], a renewed call for concerted action to achieve beneficial outcomes from environmental flows and wise freshwater management for people, biodiversity and ecosystems. I will show how this Declaration is being received globally, and who is using it (e.g. FAO, WWF, IUCN) in recent policy developments (e.g. SDGs, Post-2020 Global Biodiversity Framework).
