Water conservation aims to sustainably manage the natural resource of fresh water, protect the hydrosphere, and meet current and future human demand. Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims. Population, household size and growth and affluence all ...
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water.
Water resource policy, sometimes called water resource management or water management, encompasses the policy-making processes and legislation that affect the collection, preparation, use, disposal, and protection of water resources. [1] The long-term viability of water supply systems poses a significant challenge as a result of water resource ...
The aim of water security is to make the most of water's benefits for humans and ecosystems. The second aim is to limit the risks of destructive impacts of water to an acceptable level. [1][2] These risks include for example too much water (flood), too little water (drought and water scarcity) or poor quality (polluted) water. [1]
An important concern for hydrological ecosystems is securing minimum streamflow, especially preserving and restoring instream water allocations. [30] Fresh water is an important natural resource necessary for the survival of all ecosystems .
The practice of water management focuses on the efficiently controlling the flow of water while causing the least amount of damage to life and property. [35] This helps to provide protection in high risk areas from flooding. Irrigation management is the most efficient way to use and recycle water resources for land owners and farmers. [35]
A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
