For Desertification we have terms and definitions in 7 topics. The topics are Climate, Climatology, Ecosystems, Forestry, Physical Geography, Science and Sociology.

Desertification (Climate)

The progressive destruction or degradation of vegetative cover especially in arid or semiarid regions bordering existing deserts. Overgrazing of rangelands, large-scale cutting of forests and woodlands, drought, and burning of extensive areas all serve to destroy or degrade the land cover. The climatic impacts of this destruction include increased albedo leading to decreased precipitation, which in turn leads to less vegetative cover; increased atmospheric dust loading could lead to decreased monsoon rainfall and greater wind erosion and/or atmospheric pollution.

Desertification (Climatology)

A tendency toward more prominent desert conditions in a region

Desertification (Ecosystems)

The process of a non-desert ecosystem taking on the characteristics of a desert (arid, seemingly barren) as a result of land mismanagement or climate change

Desertification (Forestry)

A process by which land becomes increasingly unproductive and barren.

Desertification (Physical Geography)

Conversion of marginal rangeland or cropland to a more desert like land type. Desertification can be caused by overgrazing, soil erosion, prolonged drought, or climate change.

Desertification (Science)

The spread of deserts.

Desertification (Sociology)

A fertile region that has been made barren by the activities of human societies (see also DEPLETION, and POLLUTION).
