Introduction Fresh water is an indispensable resource for human livelihood‚ agricultural irrigation and economic development (Brooks‚ 2007). However‚ due to the rapid population growth and the limited reserves‚ increasing regions have faced serious scarcity of fresh water (Williamson‚ 2010). Saudi Arabia is one of the driest countries in the world (CIA‚ 2011). According to World Bank (2011)‚ the world average fresh water consumption is nearly 7000m³/year/person‚ while the water resource per capita in

desalination of water water‚ desalination of‚ process of removing soluble salts from water to render it suitable for drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long

Water scarcity and global warming Global warming is expected to account for about 20 percent of the global increase in water scarcity this century. It is predicted that global warming will alter precipitation patterns around the world‚ melt mountain glaciers‚ and worsen the extremes of droughts and floods. Global water consumption increased sixfold in the last century - more than twice the rate of population growth - and will continue growing rapidly in coming decades. Yet readily available freshwater

The Importance of Rewriting Storm Water Regulations Danielle Nielsen Goochland High School Abstract This paper observes the negative and harmful effects of water pollution and storm water runoff on the environment and the surrounding community. The most common form of water pollution is sediment runoff. It then goes on to explain the research and effectiveness of Best Management Practices (BMPs) and their positive effects. BMPs are conservation practices that can preserve or improve

They are the most basic of daily human needs‚ human rights recognised in international conventions to which Pakistan is a signatory‚ yet still far from the reach of many ordinary Pakistanis. Pakistan is due to meet the Millennium Development Goal (MDG) target of halving the number of people without access to water by 2017. However‚ the situation for sanitation is bleak: 43 million people

Global Fresh Water Shortage Fresh water shortage is a global issue. There are more than one hundred countries face different levels of fresh water shortage‚ and thirty years later there will be 28 to 33 hundred billion people have shortages of water. People lived in fresh water shortage countries cannot even have water to keep them alive. Because of the fresh water shortage‚ people lived near the southern Sahara desert abandoned farmland‚ and 200‚000 people died from that. Africa‚ Asia‚ North American
