How Does An Increasing World Population Affect The Worlds Water Supply?

How does population growth affect land and water?

As a result of population growth and cultivated land expansion in the upper and middle reaches of the river, severe problems of water shortage, water pollution, death of natural vegetation, soil salinization, desertification and sand-dust storms have occurred, particularly in downstream areas of the river basin.

What role does population play in water supply problems?

In influencing water supply problems, population growth has the role of determining the demand for water and water consumption. As population grows, the demand for water also grows. Thus, as population grows, the demand on the water supply increases. This condition leads to shortages of water supply.

How does overpopulation cause water pollution?

In addition, the population growth also leads to negative impacts on the environment such as increasing waste water, household waste, and other industrial wastes due to human has increased their activities of industrial production.

How does population growth affect quality of life?

There is an interrelationship between population and quality of life. There is an adverse effect on the quality of life if the population growth rate is high. The available means and resources become scarce. The second factors that affect the quality of life are social systems, political system and cultural values.

What is the relationship between population and water supply?

Population growth particularly will limit the amount of water available per person, because an increase in per capita water consumption driven by development will intensify water demand, straining the local water supply [17].

How does population growth affect food supply?

Increasing numbers of people often drive up demand for food, which typically results in additional use of arable land and water. The Food and Agriculture Organization projects that by 2050, population and economic growth will result in a doubling of demand for food globally.

How does energy affect population?

High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications.

Who is responsible for shortage of water?

Water shortages may be caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water. A water crisis is a situation where the available potable, unpolluted water within a region is less than that region’s demand.

What role do cities play in the demand and supply of water?

Demographic processes, such as population growth and urbanization, are such drivers that create great pressures on water resources. They directly affect water availability and quality through increased water demands and through pollution resulting from water use.

Why does rapid population growth lead to problems with water supply?

This increase in demand will cause a shortfall of almost 2000 megaliters of water by 2030. With increased wealth comes increased water demand. This is not only as a result of increased agriculture and industrial demand but also through domestic demand, much of which is virtual water that stays hidden.
