Provedor de dados: 31 Autores: Bouquot, Chris; Sperow, Mark. An optimal forest rotation model estimates potential value from timber and carbon for owners of WV abandoned mine lands (AMLs). An OLS regression provides merchantable volume and carbon density for six forest types which could sequester 0.41 Tg of carbon per year on approximately 33,800 hectares of AMLs.

Although 22 percent of land in sub-Saharan Africa is arid or semiarid rangeland, development policies have long been biased toward crop agriculture. In the wake of the Green Revolution, international and national agricultural research institutions focused on crop systems and plant breeding. As a result, the customary tenure arrangements that enabled pastoralists to move their livestock from one grazing ground to another fell out of favor. As climate-related crises and desertification have spiraled, however, research and policy interest in rangeland management issues have been renewed. As part of its strategy to seek policies for the efficient functioning of global food systems, IFPRI has been in the forefront of this research. In the 1990s, as part of a...
