Water is vital necessity of human life. Nowadays, the world is incurring a serious problem like shortage of water. Britain's chief scientist John Beddington (2010) claimed that if in the coming decade the rate of population growth climbs, the scarcity of drinkable water will become the urgent problem for all humanity. Unfortunately, lack of potable water has bad influence on people’s health and may lead to international conflicts. Because of the shortage of water people use water from unsafe sources. It also means that people can not properly wash, clean their clothes and houses. It is obvious that poor quality of water and violation of sanitary standards can cause serious diseases. Furthermore, today there is competition for water between countries, urban and rural areas and between different industries in some regions. Therefore, problems of water scarcity in the world might turn into political problems. To avoid future problems scientists suggest a lot of solutions. However, most of them have a lot of drawbacks and they are not effective in preventing the spread of disaster. It is believed that recycling of water, desalination of seawater and increase in water price are the most effective solutions. This essay will compare advantages and disadvantages of these three most effective solutions and give examples of Singapore’s long-term water policy. Like many thirsty countries, Singapore has also a great density of population. However, due to the high levels of gross domestic product, they could afford to solve this problem. It is easy to estimate solutions looking at Singapore’s national water strategy, because it includes these techniques and has achieved some practical results.

  • Water Issues in South Asia

    13430 Words  | 27 Pages

    Water Issues in South Asia If there is any single most important issue that mars bilateral relations among the countries of the subcontinent, it is water. The issues of cross-border water distribution, utilisation, management and mega irrigation/hydro-electric power projects affecting the upper and lower riparian countries are gradually taking centre-stage in defining interstate relations as water scarcity increases and both drought and floods make life too often miserable. Thanks to its location, size and contiguous borders with other South Asian countries, it is India, in its capacity as both upper and lower riparian, that has come into conflict with most of its neighbours, except Bhutan, on the cross-border water issues. Given an atmosphere of mistrust, an upper riparian India has serious issues to resolve with lower riparian Pakistan and Bangladesh and, despite being lower riparian, with the upper riparian Nepal.
