While the worlds’ population tripled in the 20th century, the use of renewable water resources has grown six-fold. It is estimated that the world population will increase by another 40 to 50 % in the following fifty years. The demand for water will be increasing, as a result of population growth combined with industrialization and urbanization, which will have serious consequences on the environment. According to WHO/UNICEF Joint Monitoring Programme (JMP), 780 million people lack access to an improved water source; which is approximately one in nine people. Water stress causes deterioration of fresh water resources in terms of quantity and quality. As about 66 per cent of the world population would be confronted with water-shortage by 2025, water from aquifers, which provide water for one-third of the world’s population, are being used out before nature can actually complement them. Water scarcity is already a focus of attention all over the world.
The shortage of fresh water reserves is a world-wide problem nowadays, which can lead to a global crisis. Firstly, it can cause agricultural crisis. 70–85 percent of water use is for agriculture, and it is assessed that the most imperiling agricultural growth is 20 percent of global grain production and we won’t have enough water to irrigate in the future. Connected with spatial and temporal variations, water is not always available, which means there is scarcer water, particularly for large concentrations of people consumption, enterprises and some other uses. Furthermore, it leads to environmental crisis. The increasing use of water resource can reduce the amount of water available for both industrial and agricultural development, and more seriously it can exert a far-reaching influence on aquatic ecosystems and their dependent species. Environmental balances are disturbed and cannot play their roles like before. Today, approximately 3 billion people, which is about half of the world’s population, live within 200 kilometers of a coastline. By 2025, this figure is likely to double. The high concentration of people in coastal regions has produced many economic benefits. But the combined effects of booming population growth and economic and technological development have aggravated the need for water.
