→Planting trees: removed some simplistic content, and merged two sections together. We should not mix up reforestation here. It's not like every arid area is suitable for forests. |

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."<ref>{{Cite journal |last1=Hulme |first1=Mike |last2=Kelly |first2=Mick |date=1993 |title=Exploring the links between Desertification and Climate Change |url=http://www.tandfonline.com/doi/abs/10.1080/00139157.1993.9929106 |journal=Environment: Science and Policy for Sustainable Development |language=en |volume=35 |issue=6 |pages=4–45 |bibcode=1993ESPSD..35f...4H |doi=10.1080/00139157.1993.9929106 |issn=0013-9157}}</ref>

Definition by UNO (1995) – Land degradation in barren, humid and sub-humid areas due to climate change and human activities is called desertification.
As of 2005, considerable controversy existed over the proper definition of the term ''desertification'' with more than 100 formal definitions in existence.<ref>{{Cite book |last=Geist |first=Helmut

As there are many different types of deserts, there are also different types of desert reclamation [[methodologies]]. An example for this is the salt flats in the [[Rub' al Khali]] desert in [[Saudi Arabia]]. These salt flats are one of the most promising desert areas for seawater agriculture and could be revitalized without the use of freshwater or much energy.<ref>[http://www.prototype-creation.de/rethinking_landscapes.pdf Rethinking landscapes, Nicol-André Berdellé July 2011] {{Webarchive|url=https://web.archive.org/web/20160817063318/http://www.prototype-creation.de/rethinking_landscapes.pdf |date=2016-08-17 }} H2O magazine</ref>
