Answer 2

Over the past decade, the issue of water crisis has become increasingly popular. In early April 2016, if one put ‘water crisis’ in Google, there were some 30 million references. Irrespective of where in the world one is located, very seldom does a week pass without a major story in the media on the so-called water crisis.

Any serious objective and comprehensive analysis of the overall water crisis issue will indicate that the world is not facing a crisis because of actual physical scarcities of water. This is true even for the most arid inhabited regions of the world. However, the world is indeed facing a crisis, because of continued mismanagement of water over decades, if not centuries. If the management process can be improved, there will be enough water in the world for all types of water uses, not only for the present but also for 2050. By 2050, the world population is projected to reach 9.7 billion, that is, 2.3 billion more than at present. Furthermore, human activities are expected to increase very significantly during this period. But even by 2050, by using good management practices, knowledge and technology available at present (in contrast to what may be available in the coming decades), and formulation and implementation of rational water policies, water crisis can be avoided. Thus, as Shakespeare said many centuries ago, the fault is with us and “not in our stars”.
