Detailed explanation-1: -Water is scarce in the country, and what little water that is available is of poor quality because of salt water intrusion. The country has built a number of desalination plants that provide most of the country’s drinking water. Desalination is the process of taking salt out of seawater and using it for drinking water.
Detailed explanation-2: -As countries in Southwest Asia have worked to modernize their systems of agriculture, water pollution has been a growing problem. Increased demand for irrigation to expand farming has led to overuse of rivers and streams.
Detailed explanation-3: -Oasis and underground river supplies also provide important sources of water for farming. Desalinization removes salt from sea water. Since areas like the Arabian Peninsula are surrounded by salt water, desalinization would greatly increase the amount of water suitable for irrigation in Southwest Asia.
Detailed explanation-4: -Most of Southwest Asia has an arid, or very dry, climate. Deserts cover most of the Arabian Peninsula and large parts of Iran. Temperatures can rise to 129°F (54°C).
