Africa isn't really referred to as one of many extra densely populated continents. but, the harmful marks of man's actions could be visible there dramatically. lots of Africa's ecological zones are fragile. huge scale soil erosion, resul tant cycles of drought and flash floods, downgrading of fauna and vegetation are famous to many commonly methods, in addition to from unique exam of some components. yet huge elements of Africa stay inaccessible. only a few scholars of Africa give you the option - or the tenacity - to commute over those gigantic components or into the hidden corners that lie past the well known routes of Africa. As FAO's neighborhood flora and fauna and nationwide Parks Officer for Africa, ANTooN DE Vos had the possibility of traveling broadly and learning and reporting at the acceleration of artificial adjustments in a lot of the continent. As an skilled practitioner of a huge and hard technology, ecology, he has made an important specialist contribution with this e-book. it's our desire that those that learn it is going to be inspired to carryon the real paintings and the worry with this topic to which Dr. DE Vos has committed lots of his wisdom, power and private commitments.

Extra resources for Africa, the Devastated Continent?: Man’s impact on the ecology of Africa
The depletion of forest reserves gradually led to the disappearance of all sources of wood supplies in the Nile valley, the desert fringes and wadis, and also along the Mediterranean coast which once carried a light forest cover. Both in the hills and on the plains north of the Atlas mountains the original forest vegetation consisting largely of oak, chestnut and pine trees has been virtually eliminated. There is no doubt that soil erosion, much accelerated by destructive wars, was one of the chief causes of the decline of agricultural production.
Much formerly forested land has been denuded. OEDEKOVEN (1970) mentions for example, that there are a number of indications that in ancient times parts of Egypt were covered with natural forest. The depletion of forest reserves gradually led to the disappearance of all sources of wood supplies in the Nile valley, the desert fringes and wadis, and also along the Mediterranean coast which once carried a light forest cover.
