    The West African cocoa belt, reaching from Sierra Leone to southern Cameroon, is the origin of about 70% of the world's cocoa (Theobroma cacao), which in turn is the basis of the livelihoods of about two million farmers. We analyze cocoa's vulnerability to climate change in the West African cocoa belt, based on climate projections for the 2050s of 19 Global Circulation Models under the Intergovernmental Panel on Climate Change intermediate emissions scenario RCP 6.0.

    This report identifies the challenges that African legislators face in overseeing their countries’ oil and mining industries, as well as best practices in use around the world and recommendations for future engagement. The report finds that international organisations, local advocacy groups, and multinational corporations have played a key role in increasing public access to information and awareness in government oversight. Also, a growing number of African legislatures are more active in the management and oversight of the extractive sector.

    Shifting cultivation, under its diverse forms of slash and burn system, is a traditional method of cultivating tropical upland soils, mostly for subsistence purposes. This traditional system of cultivation is in ecological balance with the environment and does not irreversibly degrade the soil resource, provided a sufficient length of fallow is allowed for soil restoration. However, increasing population pressures necessitate more intensive use of land. The consequence is extended cropping periods and shortened fallows.

    Policy makers as well as scientists have started to acquire an honest appreciation of the possibilities of reducing the wastage of materials which could be profitably utilized for improving or maintaining soil productivity. In addition, the great opportunities offered by making more efficient use of the potentials of biological nitrogen fixation in farming systems are now fully recognized. A number of recommendations and suggested guidelines were made by the various Working Groups during the two-week Workshop.
