    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.

    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.

    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.

    In the context of developing a practicable and cost effective method for obtaining a country’s forest area by remote sensing, the computer processing of NOAA AVHRR HRPT data covering Liberia was investigated. The only cloud-free scene then recorded turned out to be severely and unevenly affected by atmospheric haze. To mitigate the effects of this, the country was divided into six areas (strata) of more uniform haze conditions.

    Laos depends heavily on rice based agriculture systems and there is evidence that the traditional diversified diet and income base is being eroded, resulting in a negative effect on the livelihoods of the people. The opportunity to gather food in forests is diminishing and dietary diversity is being narrowed.
