In order to maintain the ecological goods and services of rivers and other hydrological regimes like wetlands, lakes, etc., environmental flow allocations (eflows) are a necessity. At the same time, water demands in India are increasing and will keep increasing and solutions like waste water treatment, pollution control, correction of leakages and wastage of water, efficient irrigation systems, efficient agricultural systems, etc., will take considerable time to evolve, even with our best efforts. So what should we do in the meantime? There are vulnerable ecological systems on the verge of collapse..How do we respond to these challenges?
