A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
These holes are oriented against the slope of the ground, [3] generating a small dike in the curved area with the soil from the hole itself, so they capture the rainwater running downhills.
Desert farming is the practice of developing agriculture in deserts. As agriculture depends upon irrigation and water supply, farming in arid regions where water is scarce is a challenge. However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]
Such techniques are known by the collective terms agroforestry and farmer-managed natural regeneration. [2] A 2010 documentary feature film, The Man Who Stopped the Desert, first screened in the UK, portrays his life. [3] Sawadogo was a native speaker of Mossi.

The Wadi Rum Consultancy of Wadi Rum Organic Farms, [1] is an example of desert greening. [2] [3] Begun in 2010, it is located in historic Wadi Rum, in southern Jordan. Overseen by permaculture expert Geoff Lawton, it has established a sustainable agriculture system.
Contour trenching (a.k.a., Continuous Contour Trench or CCT) [1] is an agricultural technique that can be easily applied in arid sub-Sahara areas to allow for water, and soil conservation, and to increase agricultural production.
The IBTS (“Integrated Biotectural System") greenhouse is a biotectural, urban development project suited for hot arid deserts. [1] [2] It was part of the Egyptian strategy for the afforestation of desert lands from 2011 until spring of 2015, when geopolitical changes like the Islamic State of Iraq and the Levant – Sinai Province in Egypt forced the project to a halt.
