Population and Water Resources (contrib. by FAO)
The impacts of population on the quantitative water needs of a locality are Between and , most all of the world's population growth is projected to take place in developing nations. Water Supply and Pollution Control, 6th ed. Population growth has had a negative impact on the quality of the It can lead to the deforestation, water pollution, and air pollution. pollution; population; urbanization correlation between urbanization and water quality parameters based on a regional perspective showed.
As a result of human intervention, waters that have been used for a variety of purposes may contain harmful constituents, including sewage, that pose threats to the environment and to the public health. Their removal can be expensive and difficult. Issues of water quantity and water quality are inseparable.
If the quality of a water source is so degraded that restoring its quality for further use is not feasible, then the source is lost for all practical purposes. Remedial actions are costly, and prevention rather than remediation should be the goal. To achieve it, the public, industries, governments, agencies, and a variety of organizations must all play a positive role.
Reducing Population Impacts The impacts of future populations on the amount and quality of water resources available for use can be lessened by modifying the local rate of population increase, by modifying the per capita use of water, and by a combination of the two approaches.
A reduction in the per capita use rate for public water has already been demonstrated in the United States. Per capita use decreased from gpcd in to gpcd in even though the nation's population increased by 7 percent during that period. Education can play a major role in bringing about such changes.
Water-stressed regions should seek to slow their population growth and reduce their per capita water use to help alleviate their water supply problems. In general, developing nations are growing faster than industrialized nations. Between andmost all of the world's population growth is projected to take place in developing nations. A reduction of population growth rate in these nations could significantly enhance the likelihood of achieving sustainability for their water supplies.
How does Population Growth Affects the Environment Sustainability? – Environmental Sustainability
Bibliography Cunningham, William P. A Global Concern, 5th ed. With the increasing pressure on available resources, many habitats are being destroyed.
The atmosphere is also negatively impacted by population growth. As the population increases, there is an increase in the amount of pressure put on the agricultural sector.
Farming is a major human activity that has transformed the land masses and it has become a direct route in which humans have affected the environment. In many countries, the need for food is so great that natural habitats are destroyed and transform into agricultural lands. This leads to extreme deforestation in many countries.
For example, most of the forest that originally covered Europe in AD are almost gone by the s Preston. Humans have also cut down trees to access timber so they can build infrastructure and other materials. Additionally, another problem that arises with the destruction of these forests is that they are the ones who use carbon dioxide for photosynthesis and release oxygen as a byproduct. Many people have said that the forests around the world act as the lungs of the world.
Without them, the carbon dioxide levels will rise and this will lead to other environmental complications that could end up being irreversible.
Furthermore, as the population continues to grow, more technologies and practices will be implemented to increase agricultural yields. As humanity continue to use these waste products, it will increase dead zones in pools, lakes, and rivers.

About half of these statistics are for people living in cites. From the projected population size of around ten billion bythe number of people who will live in urban areas is expected to increase almost two and a half billion people by that same year, on top of almost four billion people currently, putting the global urban population at about sixty five percent in Bogardi.
Urban areas have a high risk of water pollution. Runoff from streets can carry oils, heavy metals, and other containments, while sewage water can leak into ground water, bringing bacteria, nitrates, phosphorus and other chemicals. Waste dumping also can pollute existing sources of freshwater with hazardous materials and toxic chemicals.
The Effects of Overpopulation on Water Resources and Water Security
It is estimated that between forty to fifty percent of all available freshwater sources on earth are polluted Living Lakes Partnership. The combination of the expected substantial increase of people residing in urban areas and the preexisting dangers of water pollution in urban settings, will lead to a rise in the amount of water that is not potable due to pollution.Water Pollution
It is imperative that infrastructure to limit freshwater pollution is invested in in the future, by both developed and underdeveloped nations. Finally, the pressures that are put on water resources by overpopulation will lead to civil and international conflict over control of available quantities. Accounts of battles and fights over water resources dates back to BC, when Assyrians would poison, divert, and destroy water supplies in order to put their enemies under siege Pacific Institute.
Since the yearthere have been at least over one hundred and ten major conflicts over water resources either between nations or within one. Middle Eastern countries, such as Iraq, Iran, Afghanistan, Yemen, and Syria, countries in Africa like Darfur, Sudan, and Somalia, and the South American countries of Peru and Brazil have all experienced armed struggles involving scarce water supplies.
