Theories of agrarian change in Africa normally treat agricultural intensification as a linear unidirectional process that gradually engulfs entire agrarian systems as human population increases. Focusing on soil management practices, this paper disputes the alleged uniformity of intensification a...

Synthetic sex pheromone traps for the legume pod borer, Maruca vitrata (Fabricius) (Lepidoptera: Crambidae), effectively attracted males in cowpea fields at Cotonou (lat. 6°25' N) in southern Benin, where pest incidence is observed throughout the year. However, the same pheromone lures caught ver...

Whilst community forestry programmes have combined sustainable forestry with community empowerment and poverty alleviation since the late 1970s, the role of intermediary organisations in shaping the technical and political capacities of forest user groups has rarely been systematically studied. T...

Climate change will affect the livelihoods of pastoralists in arid and semi-arid lands. Using data on agro-pastoral households from northern Kenya, we explore whether migration of household members enhances adoption of agricultural innovations that aim to provide protection against weather shocks...

The establishment of the neotropical predatory mite Typhlodromalus aripo in sub-Saharan Africa has resulted in broadly successful biological control of the cassava green mite Mononychellus tanajoa throughout the cassava belt of Africa. In some mid-altitude areas and drier lowland savannahs of sub...

This study unravels the implications of outmigration for farm labour availability, managerial feminization, women’s agency, and farm production. Findings suggest that migration contributes to increased off-farm income, with higher income from international migration. While men’s labour contributi...
Rural–urban migration can have both positive and negative environmental consequences for tropical forests. Rural residents exert pressure on the environment through farming, fishing, and forest extraction, yet conversely, protecting rural livelihoods is often the motivation for conserving large a...
