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.
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.

Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
But the list of environmental costs of food production is a long one: topsoil depletion, erosion and conversion to desert from constant tillage of annual crops; overgrazing; salinization; sodification; waterlogging; high levels of fossil fuel use; reliance on inorganic fertilisers and synthetic organic pesticides; reductions in genetic ...
Agroforestry would affect the agriculture and atmosphere in Thailand in numerous ways. By planting a combination of different tree species, these trees are able to change the microclimatic conditions. [100] Nutrient cycling also occurs when trees are incorporated in the agricultural system. [100]
The Sahara Forest Project aims to provide fresh water, food and renewable energy in hot, arid regions as well as re-vegetating areas of uninhabited desert. [ 1 ] [ 2 ] The founding team was composed of Seawater Greenhouse Ltd, Exploration Architecture, Max Fordham Consulting Engineers and the Bellona Foundation .
