Water, Water, Everywhere: To Green our Deserts - Inter Press Service | Global Politics - Yemen | Scoop.it

ST.AUGUSTINE, Florida, Mar 4 2014 (IPS) - Providing water for our still growing human population is reaching crisis levels. Water is vital for agriculture, energy production and industrial processes worldwide. Floods and droughts in Asia, Latin America, Europe and the United States accompanied unprecedented typhoons and winter storms. While none could be linked directly to climate change, the debate surfaced. Mainstream media started covering these issues more broadly.


The Earth’s surface is largely covered with water. So, why has the world’s attention focused on the three percent of fresh water on our planet, on water management, pollution, waste and recycling? Yet 97 percent of the water on Earth is saline: oceans, salty lakes and brackish wetlands ignored in most policy, finance, business and public debates!


At last, unnoticed research on the 10,000 salt-loving halophyte plants which grow in deserts and thrive on seawater is coming to light. I have long reported on saline agriculture, noting that halophyte plants can provide humans with food, fibre, edible oils and biofuels. Indeed, the only biofuels that meet ethical criteria are those based on algae grown on seawater.
