Our body comprises for the most part of the water. We require water for drinking, cooking, agriculture and to run our industries. We usually take it for granted because of its availability; but when in scarcity it becomes our most precious resource. As the world population increases, the request increments for quality drinking water. Surface and groundwater assets are being used speedier than they can be energized.
Introduction As the population grows in this era, water is a need and precious resources for everyone. Water shortage can be defined as insufficient water sources to fulfil the needs of human nature. According to WWF, from 100 percent of the earth nature, 70 percent of it is water that provides us fresh water to consume, bathe in and agricultural. In the world, 3 percent of water is fresh only and 66.67 percent of it is veiled into frozen glaciers or unavailable used. Over the total of 6.2 billion people, 1.1 billion of people are not accessible to water supply, 2.7 billion are finding their water resources and diseases are faced by 2.4 billion (World Wildlife Fund 2017).
Human population growth for the last few decades has increased exponentially. Increasing human population growth lead to the emergence problems in the water resources either directly or indirectly. In terms of quality or quantity, the usefulness of water will reduce, and water damage will be even greater. Furthermore, the problem of water resources becomes complicated as the lack of management of water resources. Accordingly, if the water resources optimally use and manage, such problems can be avoided.
Water is the most crucial element on this earth, especially for the human life. Imagine if this most vital element becomes extinct? Instantly life on earth would cease because living creatures such as humans, flora, and fauna will die, and the oceans are so vast slowly dries up. That is why the problem of water is very serious in which it not only serves as an object in life but also as a subject in the regulator's life. Water becomes the object of the livelihood and welfare of the community where people use water in their daily lives.
Water wars are coming! Water is the defining security threat of the 21st century! Water is an essential resource required for sustaining life and livelihoods: safe water is required for drinking, hygiene and providing food; and adequate water to produce energy and support economic activities such as industry and transportation. On the other hand Water in the natural environment ensures the provision of a multitude of ecosystem services to support economic and cultural activities and meet basic human needs. For too long water has been an issue that is at once everywhere and nowhere (Harrington, 2013).
Water is the essence of life and a renewable resource that changes form within the hydrological cycle. There are many factors that affect the water cycle, and therefore the approach to water resource management. It is evident that water resource management is complex and requires the
Water scarcity can be influenced by many two different factors: the climate of an area and human activities. With the rapid growth of people every day, human activities impact the natural climate and landscape in many ways. One of these ways is water scarcity. Around one third of people in the world struggle with water availability because of population growth (Namara, 2010). The purpose of the study is stated in the assignment and is order to understand the topic further and provide clarity in terms of reasoning’s of water scarcity and its impact on people.
Zain Mushtaq Ms. Aqila Zaman SS 100 26th October 2015 Water Scarcity Is A Looming Problem For Pakistan, But It Is Not Getting The Attention It Deserves. Thousands have lived without love but not one has lived without water. What W.H Auden said is quite true, and in fact if this statement is not taken seriously we are most likely to lead Pakistan into a dead hole. Most Pakistanis know a lot about the country's energy crisis and its consequences on the economy. However, hardly a handful know or even talks about the much greater looming threat of water scarcity in Pakistan.
Increasing nutrients and sediments due to higher runoff, coupled with lower water levels, will negatively affect water quality (Hamilton et al., 2001). Furthermore, higher water temperatures will enhance the transfer of volatile substance from surface water bodies to the atmosphere (Schindler, 2001). There is no doubt climate change impact is not limited to the water quantity but also correlated in terms of water quality. Regrettably, there are no studies analyzing the impact of climate change on biological water quality from the developing countries, where low-quality water is used for irrigation (WHO/UNICEF, 2000). Nepal one of the least developing with high climate change impact and there is hardly any study carried out about the water quality and climate change.
Every human being needs natural resources such as water to support their lives and protect environmental quality. We desperately depend on water for drinking, energy, agriculture and transportation. The need for clean water is considered as continous and unlimited demand. Due to the importance of the need for clean water, it is a common thing if the water sector is addressed as a high priority. From time to time, the water supply and service are getting increased which sometimes imbalance with the service capability.
