paragraph_text: Water supply and sanitation
  
  One of the main challenges for Saudi Arabia is water scarcity. Substantial investments have been undertaken in seawater desalination, water distribution, sewerage and wastewater treatment. Today about 50% of drinking water comes from desalination, 40% from the mining of non-renewable groundwater, and 10% from surface water in the mountainous southwest of the country. Saudi Arabia is suffering from a major depletion of the water in its underground aquifers and a resultant break down and disintegration of its agriculture as a consequence. As a result of the catastrophe, Saudi Arabia has bought agricultural land in the United States, Argentina, and Africa. Saudi Arabia ranked as a major buyer of agricultural land in foreign countries.
  
  According to the Joint Monitoring Programme (JMP) for Water Supply and Sanitation of the WHO and UNICEF, the latest reliable source on access to water and sanitation in Saudi Arabia is the 2004 census. It indicates that 97% of the population had access to an improved source of drinking water and 99% had access to improved sanitation. For 2015, the JMP estimates that access to sanitation increased to 100%. Sanitation was primarily through on-site solutions, and about 40% of the population was connected to sewers. In 2015, 886,000 people lacked access to "improved" water.
