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...

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...

This article focuses on the ecological and economic interactions of woodland use in Western Zimbabwe. One of the aims was to investigate the use of modelling to achieve integration among disciplines. The integrated model draws on the models in the different papers in this issue of the journal. Th...

The green lacewing Chrysoperla sinica (Tjeder) (Neuroptera: Chrysopidae) is a common natural enemy of various insect pests in China and is frequently employed for augmentation biological control. Adults of this species perform migration flights after emergence, the nature of which affects its val...

The rate of forest clearing by small farmers in the humid forest zone (HFZ) of Cameroon increased significantly in a period of economic crisis dating from 1986. A random sample survey of 648 households was conducted in 54 villages in the HFZ to understand the effect of the crisis and of a 1996 cu...
