Title : Climate Change and its Impacts on Water Resources System

Abstract:

Too many individuals still mistakenly think that climate change is only a problem for the environment. It poses an all-pervasive menace, the threat to health, agriculture production; increasing surface air temperature and affecting different fields of life. It has becomes one of the most important issues in our life. It has detrimental consequences on the economy, nature, and other living things. The major sectors affected by the climate change are drinking and utility water, agriculture and industrial sectors. Water and climate change are intertwined. Scientists believe that the disruption of the water cycle and the decline in water quality are the two most significant effects of climate change. The water cycle keeps the amount of water resources in the world constant, but because climate change affects where and when those resources are available, managing those resources' quantity and quality will be challenging. Understanding how climate change will affect drinking water sources, sanitation, and the production of food and energy is very important because daily life and plans are set up in relation to hydrologic systems. On account of global warming, significant negative effects on water supplies are anticipated. The quantity of greenhouse gas emissions and the sensitivity of our planet determine how much change we can expect in the next 10 years. The 20th century was observed hottest century for 14 centuries. The average surface temperature of the globe warmed by 0.7 oC over the previous 125 years as a result of CO2 and other greenhouse gases, according to a 2006 measurement. It is without a doubt caused by human activity. The effects of climate change are widely felt around the world. Snow and ice melt, sea levels rise, and weather patterns change as a result of global warming. Despite of huge food production it is not enough to have sufficient to meet demand globally. Climate change indicators such as increase in temperature, sudden weather change (e.g. flood, drought, and storm) and increasing solar radiation result in changes in physicochemical parameters in water. For example, oxygen density in water decreases by 10% for each 3°C temperature increase. There are impacts of climate change on water resources at basin scale comprise the following. Flooding, Drought, Hydro electrical power, Agriculture, Snow mass River flow, Groundwater use and quality, Water stress in deltas, Habitat; not these but also further effects of climate change such as, Rise in Sea level, Retreating Mountain Glaciers, Temperature, Rainfall Importance, Monsoon, Climate and Deserts, Variance in Climate, Effect on Water Resources. It is very important to evaluate the climate change impacts on sea level, rainfall pattern, Land use pattern, Food & Agriculture, and to formulate the policies to reduce the losses and of climate changes.
