Why have many countries in Southwest Asia had to develop new technologies such s desalination in order to access fresh water?

Many countries in Southwest Asia face water scarcity due to their arid climates and limited natural water resources. Additionally, population growth, rapid urbanization, and industrial development have put further strain on available freshwater sources. As a result, these countries have had to develop new technologies such as desalination to access fresh water. Desalination processes involve removing salt and other impurities from seawater or brackish water to make it suitable for human consumption and agricultural use. This technology has become increasingly important in providing a reliable source of freshwater in regions where traditional water sources are limited or contaminated.
