Abstract: Climate change is always a continuing and extensive behavior of nature that is observed in any weather condition of any distinctive temperature. For a stable ecosystem and for a well-established flow of river and water resource is very much essential. For a stable health and to keep a constant health a clean drinking water supply is more essential to the community. Water is the most essential resource required for the growth of agriculture, production of energy, water source navigation, recreations and for manufacturing units. Whenever there is an increase in demand on water supply climate change have shown a positive trend and its impact is upturn. Climate change and its impact have shown a direct trend on water availability. Water scarcity on this earth show a negative trend on the environment and in turn has a direct impact on ecosystem change. Research show that by end of this century, the development in climate change will result for global warming, which has been escalated to 1.2°C to 1.5°C, and the fresh water resources has moved towards the negative trend and has contributed to the declined growth of agriculture crop. Research publications shows that about 75% of the glaciers in Himalayan are in clearing stage, and are expected to be away from this earth by the end of 2035. are likely to vanish by 2035 or before. Date available inform that Africa is under menace for surface water and the rainfall which may drop by 10% or more by the end of 2035. This will result in the shrink of the river system by not less than 17%. Most of the stream adjoining the river belongings has been sapped and drop in the yield worldwide has hastened the people. Protuberant change in climate is growing and the landform are converted into deserts and the world is going to see the floods and droughts with increase magnitude. With this study the climate change in micro and marco level will highlight the impact on Udyavara river basin also. Similar studies on land use and land cover using GIS and RS techniques will highlight the present setting and the change that may take place on development. Evaluations of the Udyavara ecosystem would define the impact of the anthropogenic activity which will influence the sustainability of the estuarine environment.
