Desert greening is the process of man-made reclamation of deserts for ecological reasons (biodiversity), farming and forestry, but also for reclamation of natural water systems and other Life support systems. It is done by various methods. So far only arid and semi-arid desert are meant when using the expression. Icy deserts are considered unsuitable. Desert greening is an important topic as it can help solve global water, energy, and food crises. It pertains to roughly 32 million square kilometres of land. ==Methods== *Managed intensive rotational grazing *Holistic management *Landscaping methods to reduce evaporation, erosion, consolidation of topsoil, sandstorms, temperature and more *Permaculture in general - harvesting runoff rainwater to grow plant communities polyculture, composting or multitrophic agriculture *Planting trees (pioneer species) and salt-loving plants such as Salicornia and Halophytes *Regeneration of salty, polluted, or degenerated soils *Floodwater retention and infiltration (flood control)〔(dry wells'' ), by Nicol-André Berdellé, May 2011〕 *Greenhouse agriculture like the Integrated Biotectural System *Seawater farming like done by the Seawater Foundation *Inland mariculture 〔(Landscapes'' ), by Nicol-André Berdellé, July 2011〕 *Prevention of overgrazing and firewood use *Training of local residents to care for plantings, water systems etc. *Planting trees with dew and rain harvesting technology like the Groasis Waterboxx. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Desert greening」の詳細全文を読む スポンサード リンク
