Although most of the earth's surface is covered with water, water shortage is a serious threat to the survival of humanity at present and in future. There is a water crisis which faces many parts of the world and it is a threat to survival of human beings since humans are primarily dependent on water. Shortage in drinking water is a major problem facing developing countries which have not taken drastic steps to harvest water and purify it to make it safe for human consumption. However, this problem is also being increasingly felt in developed countries where the population growth has strained available water resources and stretched the ability of governments and private firms to provide safe drinking water to the population. There are many conflicts around the world where people have died or have been injured as a result of clashes over a water resource.
CHAPTER TWO LITERATURE REVIEW 2.1 INTRODUCTION The exploitation of groundwater for man use started since ancient times. At first, people did not understand nature of groundwater occurrence properly; however, different methods of groundwater exploitation have been developed. Groundwater plays an important role in national development; hence, its management is of great importance. The demand for groundwater is increasing as the days go by due to a number of factors such as the relatively low cost of development, high population growth rate, high growth rate of industries, availability of groundwater at a needed place, relatively good natural quality etc. In many developing countries many people dependent on groundwater for drinking, domestic
Meeting the demands of consistently increasing population and other sectors of economy water has become an asset because of its essential role in every work. As modernization is on the verge of its highest peak, leading to the changing lifestyle of people and economy of a country as well. Increasing demand of industrial and agricultural commodities led to the evolution of water crisis lacunae to be checked for securing future of a nation and globally ( Brooks, 2007). Overall water use of agriculture, industrial and domestic sectors are 90%, 7% and 3% respectively (AQUASTAT,2015) . This reflects the agricultural sector sucking the major part of water resources as compared to other sectors which is very negligible.
The water scarcity of China, which is triggered lots of reasons, such as natural damage, inordinate emission of human industry or other reasons, which negatively influence the water pollution, also, with the climate change, the glacier is melting dramatically, warm temperature and precipitation change natural pattern and increase the desertification(News from the earth institute). China becomes drier every year, and there are varied of products related to agriculture. Two water scarcity issues of China are that uneven distribution of the water recourse and the water pollution. China’s south to north water diversion project have caused lots of positive effects in the uneven distribution of water. As China’s population and economy have improved totally, so a plan for water is essential for China development.
Water is a fundamental resource that supports human livelihood in the form of agriculture, provision of energy, environmental health and improvement of the entire social well-being. These services provided water have been reported by Connor et al., (2015), to have reduced poverty, increased economic growth and maintained sustainable development when well managed. For a sustainable world, sufficient and safe water is easily accessible by everyone and the integrity of the ecosystem is maintained. However, the unsustainable development practices and failing authorities have affected the quality and availability of water resources globally. This mishap compromises the possibility of generating social and economic benefits from water resources.
WATER CRISIS: THE PRICE OF HUMAN INFLUENCE In the past, the evolution of rivers is intimately connected to the evolution of human society. The majority of capital cities of the world are close to water, and we need water for drinking, washing, fishing and for means of transportation. Water has played a special part in our daily lives and the stable development of human beings. Without it, we, human beings, and other things surrounding us including animals and plants would not be able to survive. That is why water should be taken into great concern.
As global population increases rapidly, the demand for food increases as well, which in turn, leads to a steep rise in agricultural activities to meet the growing need for food, to feed more of the global population. However, agricultural activities have been proven to pollute water resources. Richard (2015) noted that Agricultural activities account for 53% of water pollution incidents during the years 2010 to 2012. As technology advances, fertilizers and pesticides are easily available, and also more potent in enhancing plant growth and keeping away pests. These fertilizers and pesticides that are used to speed up the growth of these crops are not disposed of properly, and pollute water resources when the pesticides or fertilizers are disposed into the water resources.
This document is concern about water because water is the most important resource needed for survival of humanbeings. This document is based on analysis of depletion of rainfall . The rate of water depletion is so high that soon whole Rajasthan will turn into desert . The problem of water depletion is also faced by many other Indian
With the current growth of the world’s population and the increase in demand for water in the agricultural industry, the issue of water scarcity is very likely to get worse and worse (Gupta, 2016). This essay will therefore critically discuss water scarcity and how one can prevent a war fought over water, as well as how one can save water and implement change to better our future nationally and globally. 2. The Importance of Water With two thirds of the earth 's surface covered by water and the human body consisting of 75 percent of it, it is clear that water is one of the core elements responsible for life on earth (Anderson, 1986). Water is very important to us because human bodies, as well as animals, cannot function without water in their systems.
The released of stored water plays a vital role in agriculture in the developing world especially, during the dry season when rainfall is scanty and also drought periods. Hydroelectric dams, aside generating power for production and manufacturing also supports irrigation systems for agricultural
