This is done through appropriate soil preparation and the introduction of suitable plant species. It is also necessary to make adequate water harvesting systems—ideally taking advantage of the degradation process of the slope, collecting runoff water in ponds around the sites to be forested.

The opposite effect is known as eutrophication or nutrient pollution. [6] Both depletion and eutrophication lead to shifts in biodiversity and species abundance (usually a decline). [7] The effects are bidirectional in that a shift in species composition in a habitat may also lead to shift in the nutrient composition. [8]

Compare heterotroph. cooperation The process by which organisms work together for mutual benefit. coral reef courtship display
Thus, eutrophication has been defined as "degradation of water quality owing to enrichment by nutrients which results in excessive plant (principally algae) growth and decay." [ 8 ] Eutrophication was recognized as a water pollution problem in European and North American lakes and reservoirs in the mid-20th century. [ 9 ]
