The most common measure is the Falkenmark index, says Dr Simon Langan,  20 Dec 2011 Modelling global water stress of the recent past: on the relative blue water demand by means of the commonly used, Water Scarcity Index. The Water Stress Index can help you: Understand where your business portfolio is most exposed to water stress. Evaluate the physical, regulatory, and reputational risks arising from water scarcity Anticipate which areas in your portfolio are most exposed to regulatory risks designed

Areas experiencing water stress and water scarcity can be identified by relative water demand ratios exceeding 0.2 and 0.4, respectively. A threshold of 0.4 (or 40% use relative to supply) signifies severely water stressed conditions (Vörösmarty et al. 2000). The combination of a water stress threshold and gridded population data

between surface temperature and water stress is based on the assumption that as a crop transpires, the evaporated water cools the leaves below that of air temperature. As the crop becomes water stressed, transpiration will decrease, and thus the leaf temperature will increase. The link between water and stress reduction is well documented. All of our organs, including our brains, need water to function properly. If you’re dehydrated, your body isn’t running well
