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 ...
From plot to scale: ex-ante assessment of conservation agriculture in Zambia
(Elsevier; Elsevier Masson, 2019)
This study combined bottom-up and top-down approaches to assess the ex-ante effects of conservation agriculture (CA)-based systems in Zambia considering both biophysical and economic factors and prevailing farm systems ...
Benefits and challenges of crop rotations in maize-based conservation agriculture (CA) cropping systems of southern Africa
Conservation agriculture (CA) based on minimum soil disturbance, crop residue retention, crop rotations and associations are being promoted in southern Africa to reverse the decline in soil fertility and crop productivity. ...
Effects of conservation agriculture on soil quality and productivity in contrasting agro-ecological environments of Zimbabwe
Experimentation by farmers with conservation agriculture (CA) is increasing in southern Africa, but local longer term data on these new production systems are scarce. This study focuses on CA research at two contrasting ...
Risk and maize-based cropping systems for smallholder Malawi farmers using conservation agriculture technologies
Agricultural production in southern Africa is constrained by numerous factors, including low soil fertility, frequent droughts and flooding, limited access to fertilizers and the use of unsustainable management techniques ...
The adaptive capacity of maize-based conservation agriculture systems to climate stress in tropical and subtropical environments: a meta-regression of yields
(Elsevier Masson, 2018)
Conservation agriculture is widely promoted across sub-Saharan Africa as a sustainable farming practice that enhances adaptive capacity to climate change. The interactions between climate stress, management, and soil are ...
Integration of conservation agriculture in smallholder farming systems of southern Africa: identification of key entry points
A component-omission experiment based on the principle of conservation agriculture (CA) was established on smallholder farms for three seasons in Murehwa and Hwedza districts, Zimbabwe; Barue district in Mozambique; Balaka ...
Conservation agriculture systems for Malawian smallholder farmers: long term effects on crop productivity, profitability and soil quality
(Cambridge University Press, 2012)
Conservation agriculture (CA) systems are based upon minimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce ...
Rotation in conservation agriculture systems of Zambia: Effects on soil quality and water relations
Conservation agriculture(CA) systems are based on minimal soil disturbance, crop residue retention and crop rotation. Although the capacity of rotations to break pest and disease cycles is generally recognized, other ...
Investigating Conservation Agriculture (CA) Systems in Zambia and Zimbabwe to Mitigate Future Effects of Climate Change
Most models predict that climate change will affect the southern African region both through temperature rises and increased frequency and severity of drought. Conservation agriculture (CA) based on minimal soil disturbance, ...
