By Henry N. Houérou

Masking a space of over one hundred thirty million km2 spanning the Mediterranean, equator and tropics, the African continent encompasses a striking geographic range. for this reason, it truly is characterized via tremendous variable climatic, edaphic and ecological stipulations, linked to a variety of normal plants and natural world, in addition to human inhabitants density, plants and cattle. during this e-book, Henry Le Hou?rou provides his bioclimatic and biogeographic type of Africa. The huge facts give you the foundation for comparisons among numerous African areas, and with areas on different continents comparable to Latin the USA or the Indian subcontinent. the consequences represent a rational foundation for nationwide, neighborhood and sub-regional rural improvement making plans, and for agricultural learn facing features comparable to plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. attainable difficulties of purposes also are tested.
