Evaluation of the Effects of Population Growth and Climate Change on Water Resources
An Indian Perspective
Keywords:
Population growth, Climate change, Water resource, IndiaAbstract
The repercussions of population growth and climate change on water resources of India is well documented and well spread. Quantifying the nation's current and future water resources as well as any possible effects of climate change and population growth on those resources is crucial. The objective of study is to provide knowledge about the different water resources, their obtainability, prospective and the implication of population growth and climate change on water availability, demands, and water use in various sectors. The present work used latest secondary source of data and maps were created to analyses the require data. The finding of the study reveals that the rapid increase of population growth and climate change have a fatalistic consequences on the current water resources. The highest average annual water availability is in the Brahmaputra river basin at 613.95 cubic km/year, while the predicted population in the same river basin for the years 2025 and 2050 will be 58.30 million and 68.59 million, respectively. The demand of the water resource rose from those regions where population concentration is high. We must develop water-efficient technology, methods for recycling and reusing wastewater, and methods for using water resources responsibly if we are to meet future water demands.
