Cities And Cities Developing Countries Are Under Environmental Stress

Water scarcity is increasing worldwide and dramatically affecting first world nations such as Spain, Australia, and the United States. All nations are now starting to recognize that the world's water is a finite resource, and that resource is being drastically altered in both availability and quality by development, climate change and population growth. In the United States, the Colorado River is experiencing rapid declines in volume. Recent studies and data suggest that the changes in frequency, intensity, and timing of the availability of water will have substantial impact on the way we live our lives in the 21st century and beyond. As Letmathe Brakeck said, “I am confident that, under present

According to the International Water Management Institute environmental research organisation global water stress is increasing, and a third of all people face some sort of water scarcity. Where demand exceeds supply and no effective management operates, there will be conflicts between the various players involved.

Water is one of the most precious resources, which support the life of almost everything in the world. Indeed, the world is covered by 75% water, but most of this water is not suitable for human consumption or use. On the same note, the world has been increasing its consumption of water due to the increasing population, leading to increased demands. The increased water consumption, which has been a result of high population, is worrying because the matter may lead to massive water shortages in the future.

Water Pollution: Clean drinking water is becoming a rare commodity. Water is becoming an economic and political issue as the human population fights for this resource. One of the options suggested is using the process of desalinization. Industrial development is filling our rivers seas and oceans with toxic pollutants which are a major threat to human health.

A nation with a lot to lose. The huge, industrial and overpopulated country we know as China, is going through a water scarcity crisis. North China’s lack of water affects more of the region than anyone can imagine. Causing negative problems for food supply, economic development, political stability, and international relations, including drying up their major rivers. What are creating these complications? Global Warming, Urbanization and Population Growth, and Industrialization are the three main causes of China’s water crisis. Of these, the biggest driver is Industrialization.

     Keeping the pollution to a minimal isn’t the easiest thing in the world to do. The major water pollutants are chemical, biological, or physical materials that

individuals are affected by this issue. The once clean water in these wells is now polluted

The water used may also pick up impurities from the sulfur so must be purified before being recycled as these impurities can also affect the ecosystem the water is released into.

The water supply now and in the future affects the population in many ways. According to “Water in 2050”, the water supply is the determining factor of how large the population may grow. In some areas lack of

Another way that water can be polluted is with chemicals from factories. Factories use water from streams, river, and lakes to power and cool off their machinery. This used water contains many chemicals from the factory processes that are released back into the normal water (Lenntech, 1988-2016). This released water is also warmer, causing the whole body of water to heat up. This causes lower oxygen levels, which can disturb the organisms living in the water (Lenntech, 1988-2016).

Within the unprecedented challenges posed by the explosive growth of urban population, the lack of water supply and sanitation is one of the most urgent and harmful issues. The relationship between water supply and cities’ welfare is very important, as cities require a huge supply of fresh water, and in turn, the way in which the city makes use of water has an impact on the availability of fresh water. It is impossible to consider a city as being ‘sustainable’, if it cannot ensure safe access to drinking water and suitable sanitation to its habitants. (Naciones Unidas, 2010)

This would allow the movement of water which helps to replenish the anoxic water with oxygen-rich water. This also helps eliminate the excess nutrients and assimilate the lower levels of waste.

First, control over the discharge can take place at the point of generation within the plant itself. Second, the polluted water can be sent to water treatment plants before it is released into the surrounding water sources. Third, the waste water can be treated within the plant and recycled again, or treated in the plant and released.

This report is about the increase in demand for water, and its’ purpose is a twofold, firstly to examine and explore some of the causes of the ever increasing issue of the scarcity
