Soil and water impacts of reforesting degraded land and regreening

Estimates of the extent of global land degradation vary between 15% and 23% of the total land surface area, representing 1964 to 3500 million hectares, respectively. Of the various forms of soil degradation, soil erosion by water is the most predominant (55%), followed by wind erosion (28%). The lives of an estimated 1.5 billion people are affected directly by land degradation whereas governments spend billions annually to remedy the adverse costs of erosion. Various global initiatives have recently advocated the need for large-scale forest and landscape restoration, such as the Global Partnership in Forest Landscape Restoration , the Bonn Challenge, and, most recently, the Commonland Foundation.

arious soil and water impacts of reforestation have been addressed in past VU University research projects conducted in Java, Fiji, Slovenia, and Brazil, while current work with various national and international partners focuses on the hydrological consequences of reforesting severely degraded soils in Nepal, the Philippines, Mexico, and Colombia.
