situation faced by a nation or community when the amount of available water is less than 1,700 cubic meters per person.

A shortage of water in plants resulting in decreased ability to function properly, because water affects all biochemical controls and is the medium for all chemical reactions. water table

A country is water-stressed if the available freshwater supply relative to water withdrawals acts as an important constraint on development. Withdrawals exceeding 20% of renewable water supply have be [..]

Water stress occurs when demand for water by people and ecosystems exceeds available supply.

The IPCC (Bates et al., 2008) define a watershed/river basin as being water stressed when either water availability per person, per year is below 1,000 m3 (100 m2) based on long-term average runoff; or the ratio of water withdrawals to long-term average annual runoff is above 0.4.

The ability, or lack thereof, to meet human and ecological demand for freshwater. Compared to scarcity, water stress is a more inclusive and broader concept. It considers several physical aspects rela [..]

a state where low water supplies limit food production and economic development, and affect human health. An area experiences water stress when annual water supplies drop below 1,700 m3 per person.
