Conference Paper 1995

Autor: Leeuw, P.N. de Reid, Robin S.

The impact of human endeavours on the environment in the struggle to eke out a living through crop and animal agriculture is examined in a holistic context. Analyses focus on all the sources of pressure that modify the vegetation cover of rural Africa, including the effects of fires and burning o...

This paper deals with foraging behaviour of cattle grazing semi-arid rangelands in the Sahel of Mali. It discusses the location of study site, vegetation in the grazing orbit, herd management and livestock behaviour. Results on seasonal variation in feed supply, selection of the annual grazing or...

In the Sahelian rangelands biomass production is constrained by soil moisture in the drier (100-250 mm) parts and by soil nutrients in the wetter parts. Similarly, for a given Sahelian range, nutrient deficiency would be more prominent in good than in poor rainfall years. To test this hypothesis,...

Autor: Leeuw, P.N. de

Presents a comparative evaluation of population estimates based on data from ground and aerial surveys for a number of districts for which contemporary records are available. Gives an exploratory analysis of aerial surveys in six northern districts to detect trends in livestock populations over t...

Published and new data from experiments conducted in several range sites in Niger and Mali were analysed to assess wet season, dry season and year-round animal weight changes, stocking rates, forage availability, feed intake and faecal excretions of cattle, sheep and goats. Herbage availability o...

Autor: Agishi, E.C. Leeuw, P.N. de

Summarises the performance of three species of stylosanthes, viz, S. guianensis cvs Cook and Schofield, S. hamata cv. Verano and S. humilis under different production systems in Nigeria, such as in pure legume pastures, mixed pastures, with crops, in rangeland and under seed production.
