    Sierra Leona

    This paper presents findings of a land-use and land-cover (LULC) change mapping exercise conducted in Freetown, Sierra Leone. Nine LULC classes were mapped from multi-temporal Landsat data of 1974, 1986 and 2000. Special attention was given to the growth or otherwise of agricultural land in relation to other LULC classes. Conversion of one land-use/-cover type to the other was identified, and its effects discussed. Major conversions occurred between agricultural lands, grasslands, evergreen forest, built-up areas and barren land.

    Global changes in climate today present hostile weather conditions which pose considerable threats to the rich and poor alike. The capacity for developing countries to cope with these impacts is weak and a development concern. The post-conflict West African nation of Sierra Leone is no exception. In fact, rural areas are exposed to high degrees of vulnerability, livelihood insecurity and hostile environments. This paper explores the experiences of rural people and identifies impacts and coping mechanisms used in response to these changes.

    Trade liberalisation processes impact differently on men and women due to the fact that men and women have different roles in production. Despite the fact that women are actively involved in international trade, WTO agreements are gender blind and as such have adverse impacts on women. The General Agreement in Trade and Service (GATS), for instance, provides for a level playing field in service provision between big foreign owned companies and small locally owned companies.

    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.

    Kissidougou in Guinea, West Africa, is characterised by so-called 'forest islands', relics - it was assumed -of original dense forest cover. It was also assumed that local cultivation practice was to blame for the destruction of the trees. However, as collaborative research led by the School of Oriental and African Studies, the Institute of Development Studies and Guinean researchers discovered, villagers had a different story to tell: that the forest islands had in fact been established over several generations as part of a process of deliberate forest management.

    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.
