Bean ( Phaseolus vulgaris check for this species in other resources L.) production in Africa is constrained by edaphic stresses. A pan-African effort, Bean Improvement for Low Fertility in Africa (BILFA), was initiated in 1990 to screen beans for tolerance to several edaphic stresses. In the fir...
Results based on a socioeconomic survey on flood plain forest fallows are presented. The study was aimed at identifying the factors influencing people's decisions on land use and forest resource utilisation, and to provide some preliminary biophysical information. It was found that 93% of local l...
PT Musi Hutan Persada, a forestry company growing wood for pulp in South Sumatra manages about 200 000 ha of forest plantations, 90% of which consists of Acacia mangium.

Smallholder farming in much of Sub-Saharan Africa is rain-fed and thus exposed to rainfall variability. Among the climate variables, rainfall is projected to decline and have an overriding effect on crop productivity. With little opportunity for supplementary irrigation for the majority of farmer...
To determine the efficiency of utilization of organic matter in agricultural production, nitrogen flow was estimated within a village-farm model in the west of Niger, West Africa. Nitrogen was focused on in this study as it is known to be a major nutrient component of organic matter and one of th...
Where there is limited availability of conventional fertilizers, the use of organic materials is considered a viable alternative to increase the productive capacity of soils. Many potential plant residues remain underutilized due to limited research on their use as a nutrient source. In this stud...
