Discusses biological options available for improvement in the productivity of pastoral systems, particularly referring to problems arising from aridity and under-nutrition, and problems of particular systems such as mortality of young stock, bush encroachment, epidemic diseases and management sys...
Describes the dif. phases in the ILCA research framework, w. regard to Livestock Systems Research (LSR), particularly the descriptive, diagnostic, design, testing & extension phases, using examples of field research on pastoral & agropastoral systems in the arid & semi arid zones of Mali, Ethiopi...
Discusses the need for data on voluntary offtake & acquisition of livestock in pastoral production systems, and considers methods through which desired data can be collected, particularly multiple-visit, and single-visit progeny history technique.
Discusses the aim of studies on vegetation & feed resources in pastoral systems, describing the collection & presentation of data in the descriptive phase; identification of constraints in the diagnostic phase; and analysis of the impact of selected variables or technical innovations on the syste...

Three papers are reviewed in this paper. The first paper presents a model of biological processes to investigate long-term effects of soil and crop long-erm effects of soil and crop management strategies while the other two papers present approaches to study crop production strategies at the ente...

Response to case studies of eco-regional approaches at the farm/enterprise level
Discusses issues related to the collection of data on labour inputs for pastoral production, considering the utility of data on labour as part of pastoral systems research, and research methods for data collection, particularly for multi-visit recall techniques and the time allocation technique.
Discusses ways of studying economics of household level activities in pastoral production systems, with particular reference to the collection and analysis of data on household income and expenditure as well as resources inventory.

The role of quantitative ecology and systems analysis in the biological control of larger grain borer
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...
