In the next few decades, global water and energy demand will increase significantly. Even though changing water demand and supply is unavoidable, there is little existing information on the expected global changes. An analysis by the Water Research Institute (WRI) attempts to reveal global water stress situations by categorizing the leading water-stressed nations by 2040 (Maddock et al. 2015). WRI uses a set of climate change models and socioeconomic parameters to score and rank future water stress conditions in 167 countries between 2020 and 2040. This study revealed that around 33 countries will experience very high water stress by 2040.

As water scarcity rises due to rapid population growth, climate change and water quality deterioration, the global demand...
