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 efficiency is the practice of reducing water consumption by measuring the amount of water required for a particular purpose and is proportionate to the amount of essential water used. [1][2] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use. [3] Solutions for water efficiency not ...
Water stress is the ratio of water use relative to water availability and is therefore a demand-driven scarcity. [1] Water scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Additionally, to conserve the maximum amount of water, watering should be carried out during early mornings on non-windy days to reduce water loss to evaporation. Drip-irrigation systems and soaker hoses are a more sustainable alternative to the traditional sprinkler system.
Environmental protection. Environmental protection is the practice of protecting the natural environment by individuals, groups and governments. [1] Its objectives are to conserve natural resources and the existing natural environment and, where it is possible, to repair damage and reverse trends. [2]
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.
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]
World Water Day is an annual United Nations (UN) observance day held on the 22nd of March that highlights the importance of fresh water. The day is used to advocate for the sustainable management of freshwater resources. [1] The theme of each year focuses on topics relevant to clean water, sanitation and hygiene (WASH), which is in line with ...
