Abstract:In a modern context of the Anthropocene, ecological sustainability of ecosystems cannot be dissociated from socio-economic challenges and therefore entails policy framework and environmental planning. The conservative estimates though suggest that c. 10×103 to 20×103 freshwater species are extinct or at risk, with the current patterns of freshwater environmental threats providing the most convincing evidences of the current crisis. A key question remaining is that with the world's population expected to grow to 9.1×109 by 2050, how will all these extra mouths be fed at an acceptable cost to our rivers? Given escalating trends in species extinction, human population, climate change, water use and development pressures, freshwater systems will remain under threat well into the future, and there is an urgent need to build adaptive capacity and new livelihood opportunities for poor river communities. Here, we looked at both the choice of farmed species and freshwater-protected areas as a path towards long-term sustainability.
