Desertification is the gradual transformation of fertile land into arid desert, caused by both natural processes and human activities. It matters because it reduces the productivity of land that people depend on for agriculture and survival, particularly affecting dryland regions around the world.

Pustynnienie – proces poszerzania się pustyń na obszarach, gdzie nie zaobserwowano w czasach historycznych pustyń. Pustynie pochłaniają prawie 6 mln hektarów ziemi rocznie, w 60 krajach zamieszkanych przez około miliard ludzi. Najbardziej dotknięte procesem pustynnienia są kraje rozwijające się, ale zagrożone są także kraje uprzemysłowione, gdzie intensywne stosowanie pestycydów, nawozów oraz intensywna melioracja prowadzą do wypłukania gleby. Inne przyczyny pustynnienia to: degradacja lasów, degradacja drzew na sawannie, zaorywanie stepów, nadmierny wypas bydła, zmiana kierunku biegu rzek, górnictwo, porzucanie tradycyjnych technik uprawy na rzecz rolnictwa towarowego.
