Despite the extensive efforts of rainwater harvesting and management (RWHM) interventions for moisture-stressed areas in Ethiopia, the adoption and wider dissemination of the newly introduced techniques have been generally meager. The objective of this study was, therefore, to develop appropriate RWHM techniques through a participatory planning process in the Central Rift Valley (CRV) dry lands of Ethiopia. To achieve this objective, a combination of literature reviews, focus group discussions, questionnaire surveys, agro-meteorological analyses and field experimentations were undertaken.

Research conducted in Mauritania.

This paper reviews the studies of property institutions that have been undertaken by researchers affiliated with the International Livestock Centre for Africa (ILCA) since 1980. Particular attention is given to the systems studies and an ongoing study of the impacts of trypanosomiasis control on property institutions. Past and current studies by other workshop participants are mentioned but not reviewed in any detail. The majority of the completed studies have been concerned with two fundamental questions: (1) How do property institutions affect the use and management of resources?

Selection of presentations made at the workshop on "Pastoral systems research in sub-Saharan Africa", describing the framework used by ILCA for pastoral systems research (PSR), examining methods used in the descriptive and diagnostic stage of PSR, and showing how the design and testing procedures are followed in practice; with particular reference to low-altitude aerial surveys, livestock surveys & household studies.

Presents a collection of conference papers defining pastoral systems research; the survey and diagnostic phase of pastoral systems research; ILCA's experience in remote sensing techniques and aerial surveys; survey of vegetation resources; livestock productivity and animal nutrition; pastoral production strategies, wealth effects, household studies, and labour data collection as well as livestock marketing studies.

Presents papers dealing with the use of crop residues as livestock feed in smallholder crop/livestock farming systems, and the role of plant breeding in maintaining or improving their nutritive value. Discusses factors limiting the nutritive value of crop residues, and the effect of genotype and environment on the nutritive value of crop residues. Outlines perspectives and implications for crop improvement programmes. Includes recommendations.
