Question

what is the importance of water as a natural resources describe any four method of conserving water​

Answer 1

important because it is needed for life to exist. Many uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water. ... It is estimated that 70% of world-wide water use is for irrigation in agriculture.

Answer 2

Water conservation includes all the policies, strategies and activities to sustainablymanage 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 US cities have already implemented policies aimed at water conservation, with much success.[2]
The goals of water conservation efforts include:

Ensuring 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 use helps to preserve freshwater habitats for local wildlife and migrating waterfowl, but also water quality.[3]
