Which of the following regions has had the lowest freshwater supply per person in recent years

Based on the consideration that the correct answer is Asia, I can contribute with some explanations.

The main Asian region that with the shortage of water is West Asia, which has content the region of the Middle East. In this locality, only 4 out of 12 countries have water levels above the internationally standardized shortage limit. These countries are rich in oil but poor in water. In the face of water scarcity, conflicts arise between countries to define who dominates the very few river basins and groundwater. An example of a water dispute exists between Israel, Lebanon, Syria and Jordan, which, as border states, dispute the domination of the Jordan River Basin.

As a solution, many countries, such as Saudi Arabia, Israel and the small nations of the Persian Gulf, are desalinating sea water, yet they are big buyers of mineral water.
