Discusses the rest period requirements and the role of stylosanthes in cereal cropping systems in the Nigerian subhumid zone. Presents results of two trials, viz, N application on maize grain yield after natural fallow, and changes in soil physical properties after diffrent land use.

In southwestern Ethiopia, recent chaotic events, changes in land tenure and introduction of tsetse fly [Glossina tachinoides] control have precipitated changes in the use of land and other natural resources. In turn, these changes have initiated shifts in rangeland biodiversity. Unexpectedly, sma...

For at least five decades, tsetse biologists have observed that the populations of some species of tsetse (particularly species in the morsitans group of flies) decline as fly habitat is converted into cultivated land and host populations are decimated by hunting. Some have even suggested that ts...

In a selected study are in Pucallpa, Peru, 151 farmer-settlers were interviewed to understand current land use dynamics. Respondents were stratified according to broad differences determined by preliminary informal surveys. Settlers included: farmers practicing slash-and-burn agriculture in upper...

In the Nigerian subhumid savanna studies of grazing behaviour by herded cattle reveal utilisation of wide range of feed resources including browse, crop residues and recent fallow, all of which are more nutritious than natural range. A comparison of grazing in a farming area and in a grazing rev...

This paper explores the potential for, and limits to, sustainable agricultural growth in semi-arid Africa, with a focus on the role of pastoralism. Examines the main pressures on pastoral systems, and on the resource base upon which these depend. The paper argues that it is premature to contempla...

Food production from livestock in small farm systems for urban populations is discussed in the context of projected human population increase, market-led demand, rising incomes, and changing consumer preferences. These will accelerate the demand for food in the future and access to it, which in t...
