The Concerns for Global Sustainability of Freshwater Ecosystems Humaira Qadri and Rouf Ahmad Bhat Abstract Water is a fundamental compound for survival of life on earth. Its unique physico-chemical properties are a hinge for biochemical metabolism in any form of biota. Environmental pollution and issues has degraded the quality of freshwater and depletes its resources from finite to limited quantity. Preservation of freshwater sources is nowadays the most pressing environmental concern due to ever increas- ing anthropogenic pressures. For the global sustainability of freshwater ecosystems, it becomes imperative to adopt ecologically sound restoration and management practices for the sustainability of life on earth.

Its unique physico-­ chemical properties are a hinge for biochemical metabolism in any form of biota. The nature and properties of water have intrigue scientists as antiquity (Sharp 2001). This is because water is anomalous in many of its physical and chemical properties. Some of exceptional properties of water are literally crucial for biota, while others have insightful special effects on the features and characteristics of living organisms (Pandey et al. 2017). Due to its unique properties, water is called the foundation of life and undoubtedly the most important requirement for economic social develop- ment. Most of the earth’s surface is covered with water (70–72%), but, the accessi- ble freshwater resources for direct human requirement is
