Problems of Water Availability
The problem of water scarcity is faced by many regions of the world. The main reason for this is the uneven distribution of rainfall. Some areas receive heavy rainfall throughout the year, whereas some areas receive scanty rainfall. As a result, some areas face the problem of floods, and others face drought-like situations. Water scarcity is faced by most parts of South Asia, Africa, Northwest Mexico, and Australia. A few basic reasons for the shortage of water are: An increase in population has led to an increase in demand for water for industries, agriculture, and domestic needs. A large amount of groundwater can be used by human beings, but it is polluted due to excessive chemical fertilizers and pesticides. Rivers and lakes are contaminated due to the discharge of untreated sewage, dumping industrial waste, household garbage, dead bodies of animals, etc. Careless use of water by human beings has led to the shortage of water all over the world. Unequal rainfall and precipitation in different seasons and different parts of the world. Conservation and Management of Water several methods can be employed to conserve water:
Recycling of used water: Water wastage can be reduced by recycling the used water with the help of technology. Effluents in water should be treated before they are drained into rivers.
Rainwater harvesting: It is a very efficieră way to conserve water. Normally the rainwater just goes to waste as it moves down the drain? In this method, rainwater is stored in specially made huge underground tanks, and from these, water is used as and when required. Afforestation: Forests help to improve the water economy by reducing runoff water and the risk of floods. Forests and vegetation bind the soil and also help in the retention of water in the soil.
Proper irrigation: Making a well-planned plan. Schedule beforehand on how much and when water is required for a crop. Keeping weeds under control and promoting the use of sprinklers to save water. The canals should be properly lined to minimize loss by water seepage.
Proper utilization of water for domestic purposes: Water can be conserved by carefully utilizing the water at home. They can check leakage in pipes, use a bucket of water to wash their car instead of a pipe, and not leave the tap dripping water, utilizing the RO wastewater to water the plants.
WATER
Water is one of nature's most important gifts to all living things. Essential to life, a person's survival depends on drinking water. The human body consists of many minerals, but nearly 55% of them are water. It is thus one of the essential elements for good health. It is necessary for the digestion and absorption of food, helps maintain proper muscle tone, supplies oxygen and nutrients to the cells, rids the body of wastes, and serves as a natural air-conditioning system.
Our Earth has a huge quantity of water. Nearly 70% of the Earth's surface is covered by water. And fortunately, it maintains its quantity on the Earth, although it may temporarily change its form. Huge quantities of water from the oceans and
