Sanaa, the capital of Yemen, may be the first capital city in the world to run out of water. Due to Yemen's defunct government, water-guzzling addiction to a drug called qat, and lack of conservation practices, Sanaa's 2 million people may become "water refugees" by the year 2025. Furthermore, water shortages compound the country's chronic poverty, malnutrition, and tribal fighting over scarce resources. Solar desalinization combined with more efficient water management can help save Sanaa.
