WHAT IS WATER MANAGEMENT??
Water management is the activity of planning, developing, distributing and ideal utilisation of water resources (or assets). Water management is to complete demands for water and seeks to allocate water on a equitable basis to satisfy all uses and demand.
Water management is the management of water assets under set strategies and controls. Water management includes management of water resources, water treatment (for e.g.: - drinking water, waste water, sewage water, industrial water), flood protection, water table, irrigation etc.
Main discussion topics of water management are economics, water quality, and environment. We see these topics as

Water is one of the world's most valuable assets, various uses of water have diminished the availability of water resources, therefore proper management is mandatory. Water resource management is an crucial issue from a few edges, for example, advancement of water bodies for future, assurance of accessible water bodies from contamination and misuse. Management of water assets in India is of vital significance to maintain one billion or more. As per the United Nations, one of every four youngsters worldwide will live in zones extremely limited water resource by 2040. Also, water stress is straightforwardly identified with territories with popularity, for example, those encountering fast, unchecked urbanization; or those that are normally water scarce Major part of water is consumed by crops, crops give us energy and energy keep us alive.
We live in a world of water but approximately 97% of it makes up the oceans. Ocean water is too salty to be used for drinking water, framing, or manufacturing. Only 3% of the world’s water is fresh, and 2% of this supply is frozen in glaciers and ice

Areas of conflict include Ganges-Brahmaputra River, Indus River and Mekong River Basins.
About 20% of the world’s aquifers today are depleted.
768 million people, at present, lack access to a safe and reliable source of water.
India
1) India has 18% of the world’s population, it has 4% of water resources of the world.
2) Annual per capita availability of water was 1,816 cubic meters in 2001.
3) Yearly per capita accessibility of water reduces from 6,042 cubic meters in the year 1947 to 1,545 cubic meter in 2011.
4) Annual per capital availability of water will further reduce to 1,340cubic meter by 2025 and to 1,140 cubic meters by the year 2050.
5) 90% of waste water discharged in rivers does not meet environmental norms.
6) 65% rainwater runoff goes into the sea, which is a major wastage.
7) Agriculture sector is the biggest users of water followed by domestic sector and industrial sector.
PRINCIPLE OF WATER MANAGEMENT
These principles hold that: (1) fresh water is a finite and vulnerable resource essential to sustain life, development, and the
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.

Currently in Canada the provinces deem who gets water and when; they also allocate water to public or private entities within their province. Currently the provinces are doing a terrible job with water management, no province has an accurate estimate of how much groundwater they possess. This is extremely problematic because they are issuing permits without knowing how much water there actually is or how many permits they should give out. The risk with this situation is that if they give out too many permits without knowing the total amount of groundwater available then there might not be enough water left for the ecosystems, or even worse when there is a drought (Olive,
Majority of Indian’s livelihoods are dependent upon land and water based occupational functions such as agriculture, animal husbandry, forestry and fisheries. India’s total land is about 329 million hectares, out of which 175 million hectares of land is non-productive hence non-profitable and therefore it requires special treatment for the same reason. In India, water availability situation is murky because of spatial and temporal variability. Both these factors are forecaste...
...management than scarcity of that resource. In some cases up to 50% water in urban areas, and 60% of the water used for agriculture is wasted through evaporation and loss. Logging and land conversion to yield to the demands of human beings have been reduced to half the world's forests, which has increased soil erosion and water scarcity.
The human race needs three things to survive; air to breathe, food to eat, and water to drink. A large majority of the public thinks these resources are infinite and plentiful. What they fail to realize is that they are not infinite, air can become polluted, food can carry pesticides, and water can transmit diseases very easily. In order to keep these necessities safe, many companies are taking the initiative by trying to cut down on pollution and stop using harmful pesticides. Water, however is not getting enough attention, especially in urban areas. Framework exists for these urban areas to be able to have successful water management, but some countries cannot afford these ideas or simply do not want
Clean and safe drinking water resources are becoming scarce as the population grows. The world is facing many problems, but the most important thing needed to survive, is water. Water is getting low in many countries, therefore residents are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands.
There will growth of water born diseases increasing health hazards and degradation of environment and ecosystems. This affects the natural environment system leading to exaction of some species. And the due contamination of water can also lower the production of agriculture products and other economy activities will decrease. If there will more water bodies pollution it also has negative effects on its environment there decline of economy of the country. Since more of the country budget have invest on the health sectors. The country major users of water are agriculture, intensification hydropower and industrialization. Urbanization is another significant challenge. Rural-urban migration increases pressure on urban infrastructure and services and cause environmental problems which will lead to water pollution.
Freshwater in the world makes up only a small portion of water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only <1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes. Many of these in later years shall need to be addressed as tension rises:
Many scientific studies also show increases in the intensity, duration, and extent of droughts, higher atmospheric temperatures, warmer sea surface temperatures, changes in precipitation patterns, and diminishing glaciers and snowpack. The bottom line is that causes of climate change, such as greenhouse gas emissions, will have to be minimized if people want to do as much as possible to solve the water crisis.

Water is on of the most precious natural resources that exist on our planet. “It is delivered from the atmosphere in the form of rain, snow, hail, fog, and condensation and returns to the atmosphere by evaporation and transpiration” (Hannigan 1969). Although many of us love activities that have to do with water, we disregard it and pollute out rivers, lakes and oceans. Slowly but surely we are going to harm out planet till no return. Protecting and conserving nature will secure a better future. 71% of earth is covered with oceans. Sounds like a lot right? Imagine ...
Water scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need, causing them to die. This eventually affects the global population. Therefore, many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling. The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well, the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development.
Water is our main source of our life. We need it to live, drink, bathe,
Water is an irreplaceable natural resource on this earth which comprises marine, estuarine, fresh water (river and lakes), ground water across coastal and inland areas. Even though there is huge water resource in this world, about 97% of water is salt water (marine) only 3% is fresh water. And in this small fraction of fresh water a major part is in the form of ice in polar region. So just 0.003% is in the form of ground water and surface water which we can use.
Water is an integral part of not only human beings but all other creatures in the world. We use it every day for different purposes such as domestic, agricultural and industrial. Water has always been a prestigious resource. However, the majority of people do not appraise water’s worth since they do not face water scarcity; whereas, in third world countries it is one of the most serious problems. Nearly 2.4 billion people have a lack of water resources in the world, shows the investigation done by the Pacific Institute, an Oakland, California-based non-profit scientific research group. Moreover, every year this number is growing gradually and more people are suffering (Bloomberg News, 2010). There are certain causes which deteriorate current situation. The most influential reasons are global warming, pollution by human-beings and overpopulation. It is known that India is one of the countries which face water scarcity so this essay will consider the possible ways of solutions of water shortage in India.
