The important position and role of mixed farming systems in land use intensification in subSaharan Africa is reviewed. This is done by examining the current situation that is followed with a justification for mixed farming. Further sections follow on changing patterns of land use, including the e...

Undersowing sorghum with stylo as a means of improving fodder quality for dry-season grazing of livestock in the subhumid zone of Nigeria was investigated. Planting either Stylosanthes guianeusis cv 'Cook' or S. hamata cv 'Verano' simultaneously with local or improved varieties of sorghum reduced...

The paper identifies poverty and malnutrition, low crop and livestock productivity, widespread land degradation and underutilization of some resources as a major problem of highlands. To tackle these problems, a systems approach to research has been adapted and research has been conducted under t...

Thiss paper presents an overview of the current status, problems and prospects for achieving a better nutrient balance to support varying levels of productivity from the three major livestock systems in Africa. In free range grazing systems, livestock nutrient deficiencies are mainly overcome by ...

Ever-increasing human population and urbanisation are intensifying the demand for agricultural commodities in sub-Saharan Africa (SSA). As a result, the traditional balance between people, their habitat and socio-economic systems is fast disappearing. Excessive deforestation, land clearing and cu...

Investigates Nitrogen and Phosphorus transfers in a crop - livestock system in the subhumid zone of Nigeria. Estimates N and P removed from cropland during crop residue grazing and returned to the land through manure, and the contribution crop residues make to cattle diet during the dry season.

Past attempts to alleviate the problems of poor farmers engaged in mixed-crop-livestock production have generally focussed on the design and diffusion of new technologies targeted on specific components of the agroecosystem. Unfortunately, such piece-meal efforts have had little impact in the dev...

The problem of seasonal shortages of herbage production from natural pastures in the Ethiopian highlands was investigated. This was done by comparing the available biomass amounts on the pastures with biomass amounts required for livestock grazing and for protecting land slope from soil erosion w...

Efffects of livestock grazing on surface runoff and soil erosion at varying slopes were studied in pasture lands within Ginchi watershed, Ethiopia. The results showed that livestock grazing in the watershed followed distinct seasonal and spatial patterns during the rainy season, grazing pressure ...

The species composition of grazing lands can be influenced by livestock and grazing pressure. A study on manure seed bank was conducted in Ghinchi highland Research Site in Ethiopia between 1995 and 1997. the data on species composition and life-form of the plants germinating in pots receiving ai...
