Metadata only record This document presents an analysis of Fulani pastoral farming systems that focuses on how pastoralists use silvopastoral land. It aims to provide the missing knowledge needed to implement the resource management ('gestion des terroirs') approach at village level. In this region the influence of pastoral land use on the environment appears to be less pronounced than that of crop cultivation, even though levels of animal production are reasonable. The carrying capacity of the region has not yet been attained. Current constraints to pastoral land use in the region arise from the encroachment of cropland at the expense of pastoral land, and the increase in animal numbers. To develop sustainable natural resource management at village level that includes Fulani pastoral land use, the key factors appear to be the integration of livestock husbandry and cropland cultivation at household level, agreements between pastoralists and cropland farmers on land tenure and resource management, and support targeting of Fulani households (which have so far been neglected). Specific recommendations are given. (CAB Abstract)

Metadata only record The article examines the application of a geographical information system (GIS) project to the sustainable development of a natural resource within the context of a fisheries production system in the Central Delta of the River Niger in Mali. The project, which takes into account the specific characteristics of the natural and social environment, results from the findings of a research programme carried out between 1986-94 to investigate the organization and dynamics of a production sector which is based on the exploitation of a natural renewable resource. The Central Delta of the Niger contributes around 90% annually of total fish production in Mali. Over recent years, however, increasing interest from developers, restrictions on fishing and conflict between producers have caused a crisis of production. Through the development of a system of spatial representation of the interactions between the social and natural systems of the area, the objectives of the GIS are to solve the conflicts associated with resource use, develop an effective system of resource management and ensure the long term sustainability of the resource.

Metadata only record The paper proposes a theory of technology development for semi-arid regions. It then evaluates the theory by reviewing the characteristics of technologies successfully introduced into the regions. Modeling is then used to identify some constraints to further technology introduction of the type proposed. Some specific policy recommendations to accelerate technology introduction are made.
