TL;DR: In this paper, it is estimated that reforestation of a third of all degraded lands in dry or montane areas and afforestation of about a fifth of the degraded area of croplands in dry regions (61.5 million ha) would prevent projected fuelwood deficits in those regions by the year 2000.
Abstract: SUMMARY There are an estimated 2,077 million ha of degraded lands in the tropics, of which 758 million ha have a theoretical potential for forest replenishment if the substantial area of low productivity rangelands is disregarded. The total includes 418 million ha in dry or montane areas requiring afforestation or reforestation; 137 million ha of tropical rain forests in need of protected regeneration or silvicultural manipulation; and 203 million ha of forest fallows in the humid tropics which could be reforested. Based upon previous forecasts of future demand for fuelwood and industrial wood it is estimated that reforestation of a third of all degraded lands in montane regions (26.8 million ha) and afforestation of about a fifth of the degraded area of croplands in dry regions (61.5 million ha) would prevent projected fuelwood deficits in those regions by the year 2000. In the humid tropics, an additional 26.6 million ha of medium- rotation high-grade hardwood plantations could, with the current plantat...
