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 ]
The total volume of water on Earth is estimated at 1.386 billion km 3 (333 million cubic miles), with 97.5% being salt water and 2.5% being freshwater. Of the freshwater, only 0.3% is in liquid form on the surface. [ 2][ 3][ 4] Because the oceans that cover roughly 70.8% of the area of Earth reflect blue light, Earth appears blue from space ...
China's fresh water resources include 2500 cubic kilometers of mean annual run-off in its rivers and 828.8 cubic kilometers of groundwater recharge.As pumping water draws water from nearby rivers, the total available resource is less than the sum of surface and groundwater, and this is only 2,821.4 cubic kilometers. 80% of these resources are in the South of China.

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.
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 ...
A 2023 paper concluded that under the high-warming SSP5–8.5 scenario, 64.15% of amphibians would lose at least some habitat by 2100 purely due to an increase in aridity, with 33.26% losing over half of it, and 16.21% finding their entire current habitat too dry for them to survive in.
