    Níger, África, África occidental

    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.

  2. Library Resource
    Documentos de conferencias e informes
    Diciembre, 1983

    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 systems.

  3. Library Resource
    Documentos de conferencias e informes
    Diciembre, 1983

    Indicates factors that must be considered when designing pastoral systems research, esp. the need to maintain complementantrity among various types of research; the need for policy orientation when carrying out research; and setting up of priorities & opportunities. Includes case examples from work carried out by the ILCA subhumid programme.

  4. Library Resource
    Documentos de conferencias e informes
    Diciembre, 1983

    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.

    Diciembre, 1983

    Reviews differences between crop production and pastoral production, considering their effects on research possibilities; and describes basic methods that may be used to collect household level data, esp. informal & formal surveys, enumeration and the use of questionnaires.

  6. Library Resource

    Documentos de conferencias e informes
    Diciembre, 1983

    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 systems' functioning, and the development of adapted technology in the experimental phase.

  9. Library Resource
    Documentos de conferencias e informes
    Diciembre, 1983

    Describes techniques of long-and short-term measurements of changes in vegetation and feed resources in pastoral systems, with particular reference to sampling techniques and costs of the various methods.
