Saudi Arabia and China are among the countries that have turned to the US and other countries looking for water.
Climate change will make water scarcity a critical security issue globally, wealthier countries have begun to look outside their borders to meet their water needs. Saudi Arabia and China have come to the USA to help solve their water problems and feed their people. In 2014 SA bought farmland in Arizona to grow alfalfa to feed its cows back home. Huge amounts of water are needed to grow that crop , which is why they came. Facing water scarcity China imports half the world’s soybeans and 25% of the american supply of pork.
National security experts have long worried about the implications of water scarcity. Confronting issues involving food, water, energy , and disease will become more frequent.
Consider it takes 500 tons of water to grow 1 ton of soybeans. Access to an abundance of fresh water is critical. This access has become an issue in many parts of the world. In North America we have been shielded from this by our relative abundance, but it is only a question of time before the crisis hits home.
