Afforestation can also improve the local climate through increased rainfall and by being a barrier against high winds.

German-Israeli researcher Michael Evenari has shown how novel techniques were developed, such as runoff rainwater collection and management systems, which harvested water from larger areas and directed it onto smaller plots. [4] This allowed the cultivation of plants with much higher water needs than the given arid environment could provide for ...
Aridification is the process of a region becoming increasingly arid, or dry.It refers to long term change, [1] rather than seasonal variation. It is often measured as the reduction of average soil moisture content.
