Water Stress Effect Defined
The following is in context to Sustainable Development, because it's common for a single word to have multiple meanings you will find additional research links near the bottom of the page.
"The closing of the stomata by a plant in response to excessive water loss through transpiration or in response to drought conditions. The stomatal closing reduces CO2 uptake as well as water loss, thus decreasing the photosynthetic rate. However, under conditions of elevated CO2 concentration, the CO2 gradient between the atmosphere and the leaf is higher than under ambient conditions, and CO2 can pass through partially closed stomates at a rate similar to that under conditions of lower CO2 and open stomates. The humidity gradient remains the same at higher CO2, and transpiration is impeded. The net result is improved water-use efficiency by some plants."
