Describes West African transhumant pastoralism, briefly analysing major characteristics of this mode of production, reviews differences in land tenure & farm size, livestock holdings, labour intensity, income & level of technical knowledge of African pastoral & cropping systems, and assesses appl...


Leeuw, P.N. de[Pastoral production systems and land utilisation types]Pastoral production systems and land utilisation types

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...

Lebbie, S.H.B.Leeuw, P.N. de[Health and production monitoring in ruminant livestock in the developing world]Health and production monitoring in ruminant livestock in the developing world

Grazing and herd management in sub-Saharan Africa is discussed in a broad ecological, agricultural and geopolitical context. A brief historical overview of the Development of the livestock sector is presented, followed by an assessment of feed supplies and livestock densities in major ecological ...


Leeuw, P.N. deHiernaux, Pierre H.Y.Mihoso, V.M.[Grazing pressure in sub-Saharan Africa: An historical perspective]Grazing pressure in sub-Saharan Africa: An historical perspective

Analyses the productivity of different livestock production systems in sub-Saharan Africa and compares the output with higher-input ranching systems in similar environments to indicate potential improvements in productivity in response to better feeding, management and health care. Gives emphasis...


Leeuw, P.N. de[Interactive effects of environment, management and mortality on cattle productivity in livestock systems in sub-Saharan Africa]Interactive effects of environment, management and mortality on cattle productivity in livestock systems in sub-Saharan Africa

Discusses how low level aerial survey can be used to diagnose constraints within pastoral systems and the relative cost effectiveness of such operations, with particular reference to flight & sample procedures and information collection and analysis; presents some results from low-altitutde aeria...


Milligan, K.Leeuw, P.N. de[Low altitude aerial surveys in pastoral systems research]Low altitude aerial surveys in pastoral systems research

Presents findings and proposals of a team which studied the pastoral zone of Niger to forumlate a development programme, describing the existing production systems and constraints related to range resources, nutrition, water points and diseases.


Leeuw, P.N. deHaan, C. de[A proposal for pastoral development in the Republic of Niger]A proposal for pastoral development in the Republic of Niger

Reviews most recent applications of methodologies for resource surveys appropriate to pastoral & agro-pastoral regions in Africa, with particular reference to remote sensing methodologies, viz. satellite imagery, aerial photography, side-looking radar (SLR), spectral radiance and low-altitutde ae...

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.


Agishi, E.C.Leeuw, P.N. de[The performance of stylosanthes species in different production systems in Nigeria]The performance of stylosanthes species in different production systems in Nigeria

The potential supply of nutrients from excreta voided by livestock and what is potentially available for transfer to cropland are examined within a West African context. Nutrient output from cattle is derived from a simulation model that predicts nutrient intake in relation to animal performance ...
