Sheep and goats, men and women: Household relations and small ruminant development in southwest Nigeria

Christine Okali; James Sumberg

Abstract Small ruminant production systems are described for the humid areas of southern Nigeria. Differences in ownership patterns between men and women are detailed and the unique nature of small ruminants among agricultural resources is emphasized. Development paths that maintain small ruminants in their positions as minor enterprises in existing farming systems are delineated, and the implications of these models discussed in the light of intra-household processes. Alternative models are reviewed and compared.

Tomatoes, Decentralization, and Environmental Management in Brong Ahafo, Ghana

James Sumberg; Christine Okali

ABSTRACT This article uses the example of environmental management issues being raised in the context of intensive, small-scale tomato production in Ghana to explore one of the key challenges of decentralization, how to reconcile the potential conflicting interests of local populations and stakeholders at other levels. It explores the contradiction between the push for more local natural resource management and the continuing role of central government in the setting of environmental policy. The article argues for a flexible, coevolutionary approach to environmental regulation so that rural residents whose livelihoods are directly dependent on natural resources are not unduly disadvantaged by policy and regulations that may have limited immediate relevance to their locality.
