water resources​

Answer 1

Answer:

Water conservation includes all the policies, strategies and activities to sustainably manage the natural resource of fresh water, to protect the hydrosphere, and to meet the current and future human demand. Population, household size and growth and affluence all affect how much water is used. Factors such as climate change have increased pressures on natural water resources especially in manufacturing and agricultural irrigation.[1] Many countries have already implemented policies aimed at water conservation, with much success.

The goals of water conservation efforts include:

Ensuring the availability of water for future generations where the withdrawal of freshwater from an ecosystem does not exceed its natural replacement rate.

Energy conservation as water pumping, delivery and wastewater treatment facilities consume a significant amount of energy. In some regions of the world over 15% of total electricity consumption is devoted to water management.

Habitat conservation where minimizing human water usage helps to preserve freshwater habitats for local wildlife and migrating waterfowl, but also water quality.

The key activities to conserve water are as follows:

Any beneficial reduction in water loss, use and waste of resources.[4]

Avoiding any damage to water quality.

Improving water management practices that reduce the use or enhance the beneficial use of water.[5][6]

One of the strategies in water conservation is rain water harvesting.[7] Digging ponds, lakes, canals, expanding the water reservoir, and installing rain water catching ducts and filtration systems on homes are different methods of harvesting rain water. Many people in many countries keep clean containers so they can boil it and drink it, which is useful to supply water to the needy.[7] Harvested and filtered rain water can be used for toilets, home gardening, lawn irrigation, and small scale agriculture.[7]

Another strategy in water conservation is protecting groundwater resources. When precipitation occurs, some infiltrates the soil and goes underground.[8] Water in this saturation zone is called groundwater.[8] Contamination of groundwater causes the groundwater water supply to not be able to be used as a resource of fresh drinking water and the natural regeneration of contaminated groundwater can take years to replenish.Some examples of potential sources of groundwater contamination include storage tanks, septic systems, uncontrolled hazardous waste, landfills, atmospheric contaminants, chemicals, and road salts.Contamination of groundwater decreases the replenishment of available freshwater so taking preventative measures by protecting groundwater resources from contamination is an important aspect of water conservation.

An additional strategy to water conservation is practicing sustainable methods of utilizing groundwater resources.[7] Groundwater flows due to gravity and eventually discharges into streams.[8] Excess pumping of groundwater leads to a decrease in groundwater levels and if continued it can exhaust the resource.[7] Ground and surface waters are connected and overuse of groundwater can reduce and, in extreme examples, diminish the water supply of lakes, rivers, and streams.[9] In coastal regions, over pumping groundwater can increase saltwater intrusion which results in the contamination of groundwater water supply.[9] Sustainable use of groundwater is essential in water conservation.
