Failing to yield? ploughs, conservation agriculture and the problem of agricultural intensification: an example from the Zambezi Valley, Zimbabwe
Agricultural intensification, or increasing yield, has been a persistent theme in policy interventions in African smallholder agriculture. This article focuses on two hegemonic policy models of such intensification: (1) ...
Agriculture and nature: Trouble and strife?
Global demand for agricultural products is expected to double in the next decades, putting tremendous pressure on agriculture to produce more. The bulk of this increase will come from developing countries, which host most ...
Comparative performance of conservation agriculture and current smallholder farming practices in semi-arid Zimbabwe
Conservationagriculture (CA) is currently promoted in sub-humid and semi-arid areas of sub-Saharan Africa as a means to increase crop water use efficiency and stabilize yields. In this study, conducted during three consecutive ...
Conservation agriculture with trees amplifies negative effects of reduced tillage on maize performance in East Africa
Conservation agriculture (CA) is widely promoted in sub-Saharan Africa both in open fields and in agroforestry where the practice is known as ‘conservation agriculture with trees’ (CAWT). Although advantages and disadvantages ...
Agro-ecological options for fall armyworm (Spodoptera frugiperda JE Smith) management : providing low-cost, smallholder friendly solutions to an invasive pest
Fall armyworm (FAW), a voracious agricultural pest native to North and South America, was first detected on the African continent in 2016 and has subsequently spread throughout the continent and across Asia. It has been ...
Where to target conservation agriculture for african smallholders? How to overcome challenges associated with its implementation? experience from Eastern and Southern Africa
Since the paper by Giller et al. (2009), the debate surrounding the suitability of conservation agriculture (CA) for African smallholders has remained polarized between proponents and opponents. The debate also gave rise ...
Field-scale modeling of tree–crop interactions : Challenges and development needs
(Elsevier Masson, 2016)
Agroforestry has attracted considerable attention in recent years because of its potential to reduce poverty, improve food security, reduce land degradation and mitigate climate change. However, progress in promoting ...
Unpacking the push-pull system : assessing the contribution of companion crops along a gradient of landscape complexity
(Elsevier Masson, 2018)
The push-pull system, a stimulo-deterrent cropping strategy consisting of intercropping cereals with herbaceous legumes and surrounded by fodder grasses, is presented as a promising crop diversification strategy for ...
Different ways to cut a cake : comparing expert-based and statistical typologies to target sustainable intensification technologies, a case-study in Southern Ethiopia
(Cambridge University Press, 2016)
Understanding farm diversity is essential to delineate recommendation domains for new technologies, but diversity is a subjective concept, and can be described differently depending on the way it is perceived. Historically, ...
Conservation agriculture in African mixed crop-livestock systems: Expanding the niche
Competition for crop residues between livestock feeding and soil mulching is a major cause of the low and slow adoption of conservation agriculture (CA) in sub-Saharan Africa. Retaining crop residues in the field is not ...
