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.
These holes are oriented against the slope of the ground, [3] generating a small dike in the curved area with the soil from the hole itself, so they capture the rainwater running downhills.
The Society for Ecological Restoration defines restoration as "the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed." [1] Restoration ecology is the academic study of the science of restoration, whereas ecological restoration is the implementation by practitioners. [21]
Examples of Ecoscaping techniques include: Using natural products instead of artificial decoration; Planting trees and minimizing the use of pesticides and artificial fertilizers; Creating out-buildings, decks, trellises, etc. that work in with the land. Rainwater harvesting; Creating a self-contained water reservoir for water balance.

Greening the Desert II site, Dead Sea Valley Jordan (photographed 2018) is an oasification project. In hydrology, oasification is the antonym to desertification by soil erosion. This technique has limited application and is normally considered for much smaller areas than those threatened by desertification. [citation needed]
Contour trenching (a.k.a., Continuous Contour Trench or CCT) [1] is an agricultural technique that can be easily applied in arid sub-Sahara areas to allow for water, and soil conservation, and to increase agricultural production.
