In the Sahara a breakthrough technology is emerging for drought solutions... The Sahara is one of the hottest places on Earth, and is considered the largest hot desert in the world, its an extremely harsh environment receiving less than 1 inch of rain every year. Despite this 2.5 million inhabitants live within the Sahara, making it one of the least densely populated places on Earth with less than 1 person per square mile, however the desert is advancing. The Sahara spans across 10 countries and is expanding southward at a rate of 48 km a year, further degrading the land and eradicating the already scarce livelihoods of populations. It is now encroaching on more populated areas within the Sahel region, where 44 million people live. It is said to be 10 percent larger than it was a century ago. In this region temperatures are rising faster than anywhere else on Earth and since the 1970s it has been affected by severe droughts. This has come at a huge cost: land degradation is currently estimated at about $490bn per year, which is much higher than the cost of action to prevent it. The Sahara desert is just one example across the world of how our deserts are advancing, and how global climate change is affecting these areas negatively. Its estimated that more than one billion people, one-eighth of the Earth's population, actually live in desert regions and the livelihoods of a further 1 billion people in some 100 countries are threatened by desertification. Desertification refers to the land degradation in arid, semi-arid and sub-humid areas resulting from various factors, including climatic variations and human activities. When land degradation happens in the world's drylands, it often creates desert-like conditions. Drylands take up 41.3% of the land surface and up to 44% of all the world's cultivated systems are in the drylands. Water scarcity is the gap between the demand for water and it’s supply, in dry-lands there is a high demand for water despite their being a lack of supply. Water scarcity it is said to affect between 1-2 billion people, most of them living in the drylands. It is estimated that nearly half of the world's population in 2030 will be living in areas of high water stress and it could displace up to 700 million people. It is for this reason innovators across the world are trying to turn this around. In this video we will show you how the first ever off grid water production machine is creating water from thin air in the desert, this breakthrough technology is on the forefront of drought solutions helping provide free water for billions of people living in dry land across the world….
