The Rainforests of West Africa: Ecology — Threats — by Claude Martin

By Claude Martin

Nowhere eise on this planet did industrialized international locations depart such early marks within the rainforest as in West Africa. earlier and current advancements listed below are in a single method or the opposite major for rainforests on different continents as weil. West Africa is a pioneer in either a superb and a nasty experience. this can be cause adequate to take a better Iook on the background of wet tropical West Africa. till lately, not anyone rather appeared to be drawn to the rainforests apart from a couple of experts. The world's clinical neighborhood overlooked to check the incalculable riches of tropical forests, to make the general public conscious of them and their due significance. even supposing interdisciplinary learn has been a well-liked subject for a few a long time now, it used to be no longer utilized to simply the main advanced habitat on the earth. Scientists from all fields studied purely that which used to be simplest to list, likely ignorant of a myriad of info looking forward to nearer exam. Botanists wentabout developing their herbariums and paid a lot too little cognizance to the crops as a complete, or to the importance of worthwhile crops for neighborhood populations. Zoologists, too, busied themselves with gathering and describing species. Anthropologists, however, tended to miss faunal info: of their lack of knowledge of the animal international, they wrote of tigers and deer in Africa. and at last, foresters observed neither the wooded area nor the timber for the trees - or even stressed rainforests with monocultures of fir bushes.

Ecological economics: an introduction

Ecological economics is an exhilarating interdisciplinary box of analysis that mixes insights from the common sciences, economics, philosophy and different fields to enhance cutting edge ways to environmental difficulties. It attracts on a variety of analytical views, a few radical others extra traditional, to construct a extra whole knowing of human-ecosystem interactions.

Sources, Sinks and Sustainability

Source-sink theories supply an easy but robust framework for knowing how the styles, techniques and dynamics of ecological structures differ and have interaction over area and time. Integrating a number of study fields, together with inhabitants biology and panorama ecology, this publication provides the most recent advances in source-sink theories, equipment and purposes within the conservation and administration of normal assets and biodiversity.

Application of Threshold Concepts in Natural Resource Decision Making

Typical source managers face a posh decision-making atmosphere characterised through the aptitude incidence of fast and abrupt ecological switch. those abrupt alterations are poorly accommodated by means of conventional average source making plans and decision-making procedures. As acceptance of threshold strategies has elevated, modern types of ecological structures were converted to raised symbolize a broader variety of ecological process dynamics.

Environmental Management of River Basin Ecosystems

This e-book bargains a distinct number of inter- and multidisciplinary reviews on river platforms. Rivers were the major resource of sustenance because the creation of civilization and river structures usually shape the root for agriculture, delivery, water, and land for family, advertisement, and business actions, fostering monetary prosperity.

Example text

Swiss forest engineer Adrian Sommer differentiated in the study between the natural distribution area of tropical moist forests and the actual forest cover then remaining [12]. 62 million square kilometers, a surface about the size of the combined areas of india, Nepal, Bhutan and Bangladesh. 69 million square kilometers (74%) in Central Africa, 680000 square kilometers (19%) in West Africa and 250 000 square kilometers (7 %) in East Africa including the islands off the east coast. it is peculiar, however, that Angola with 80 000 square kilometers of tropical moist forest was listed under West Africa.

39 Angolan black-and-white colobus (Co/obus angolensis) Diversity decreases steadily however, the further one moves from the core of an endemism center. 63% of the forest-dwelling mammal species in Africa occur within the region of a single center of endemism [17]. lnterestingly enough, these pockets of species richness are found exclusively in zones of maximal precipitation and correspond with the forest refuge areas of the former cool and dry periods. The colobus monkey quickly moving through the branches of the forest canopy, or the duiker antelope darting through the underbrush of the rainforest both serve to remind us of the drastic climatic events in Africa tens of thousands of years ago!

69 million square kilometers (74%) in Central Africa, 680000 square kilometers (19%) in West Africa and 250 000 square kilometers (7 %) in East Africa including the islands off the east coast. it is peculiar, however, that Angola with 80 000 square kilometers of tropical moist forest was listed under West Africa. Further, the mosaic of rainforest and savannah vegetation along the edges of the distribution area was included in the category of rainforest. This theoreticai area of distribution determined by the study was probably valid until the beginning of last century.
