The demand on existing freshwater supplies will be magnified To reclaim damaged water will require an international commitment to dramatically reduce human impacts on climate. Water is best protected in natural watersheds . Bioregionalism is the practice of living within the constraints of a natural ecosystem. Therefore, if living within the ecological constraints of a region is key to developing a sustainable society, watersheds are an excellent starting point for establishing bioregional practices. An advantage of thinking in watershed terms is that water flow does not respect nation-state borders.
Watershed management offers a more interdisciplinary approach to protecting water.
Watershed management is a way to break the gridlock among international, national, local and tribal governments that has plagued water policy around the world for so long. Watersheds, not political or bureaucratic boundaries, will lead to more collaborative protection and decision-making. Because water, like air, belongs to the earth and all species, no one has the right to appropriate it or profit from it at someone else's expense. Water then, is a public trust that must be protected at all levels of government and communities everywhere. Therefore, water should not be privatized, commodified, traded or exported in bulk for commercial purpose.
