WATER CYCLE AND CIRCULAR ECONOMY WITH NETZERO: PROSPECTIVE ROLE OF THE GEOGRAPHERS

In the coming future, the World War will be fought over the shortage of water, is not a joke. Today the point of concern is water security.Even as the world is struggling for everything increasing scarcity of water is most dangerous. With the rapid development of technologies and industries, global warming and climate change has caused serious threats to every element of the environment. Among these threats, the most evident impacts are the increasing and widespread water stresses experienced bycities globally. The emission of CO2 has worsened the situation further. As the COP 26 Conference led the world to believe that NetZero or CO2 less planet must be attained, a water cycle and circular economy leading to NetZero are inevitable for all nations to be achieved by 2075. The need to preserve, conserve, recycle and reproduce water for energy, domestic and industrial usage cannot be overemphasized. Against this backdrop of the global scenario that is dismal at best, NetZero is only the escape route. The present paper is an attempt to analyze the prospective rolegeographers across the world can play in adopting a water cycle,analyzing,a systemic approach to deliver water reuse at multiple scales, how cities can articulate and lead a system-wide transformation agenda,how urban households use water and establish a circular economy in attaining NetZero locally and globally.
