Water Scarcity in the USA

In the past 50 years, the population of the United States has doubled. During this time, the total water usage per capita has almost tripled. Since the end of the Second World War, people have gradually moved from rural areas to cities. As a result, the domestic self-sufficiency population has drastically decreased, and the demand for public water supply systems is also increasing. These factors, coupled with specific economic trends, precipitation and global climate change, will be a major challenge over the next few years.

Water shortage is either a natural phenomenon or an artificial phenomenon. Therefore, they must be divided into two categories: economic shortages and material shortages. The lack of economy means that finding reliable and secure water sources is time consuming and expensive. Alternatively, physical shortage refers to a situation where water resources in a given area are short. In 2006, the United Nations Economic Commission for Africa estimated that 300 million people out of the 800 million people living in the African continent live in a low-water environment. Especially in northern Africa and southern Africa, the global temperature rise accompanying climate change exacerbates the water cycle leading to the dry season and increases the risk of more extreme and frequent drought.

Actual water shortages are due to insufficient natural water resources to meet the needs of the community, caused by insufficient management of adequate available water resources. According to the report of the United Nations Development Program, most countries have sufficient water to meet the needs of home, industry, agriculture and the environment, but the latter is widely thought that it is the cause of water shortage It will serve it in an understandable way. Approximately one fifth of the world's population currently lives in areas affected by a serious water shortage. Water resources, including the water resources necessary to function effectively in the ecosystem, are insufficient to meet the needs of the country and region. Dry areas frequently encounter material shortages
