Ecology provides the essential basis for nature conservation. Maintaining a mosaic of habitats ensures the survival of a rich variety of species. For instance, heathland is a valued landscape that is fast disappearing throughout much of Western.

The grassland biome includes terrestrial habitats that are dominated by grasses and have relatively few large trees or shrubs. There are three main types of grasslands—temperate grasslands, tropical grasslands (also known as savannas), and steppe grasslands.

A case study in sub-Saharan Africa am highly grateful to CSFD for devoting this 9th Dossier to the topic of pastoralism in sub-Saharan Africa and for inviting me to preface it.

Sub-Saharan Africa has been the focus of an intense race for oil by the West, China, India, and other emerging economies, even though it holds only 10% of proven oil reserves, less than the Middle East. This race has been referred to as the second Scramble for Africa.

Sub-Saharan Africa suffers from some serious environmental problems, including deforestation, soil erosion, desertification, wetland. sizable tracts of land to protect watersheds, prevent soil erosion, allow natural regeneration to take place, and preserve habitats, species, and biodiversity. As mentioned earlier, current knowledge of the ecology of tropical forests and grasslands is still rudimentary.
