Conservation agriculture (CA) based on hand-hoe prepared planting basins is being widely promoted in southern Africa, targeting resource-constrained farmers with limited access to draft power. This study was conducted across 15 districts covering four agro-ecological zones in Zimbabwe where paire...

Increasing sources of livelihoods and of income through appropriate innovation platforms may contribute to reduced food insecurity and increase resilience of rain-fed smallholder farmers in semi-arid areas of Zimbabwe. Negative impacts of climate change and variability are mainly projected for sm...

Assessment of innovations for sustainable livelihoods for smallholder farmers in response to changing climates in semi-arid Zimbabwe through farmer perceptions
Climate change has resulted in increased vulnerability of smallholder farmers in marginal areas of Zimbabwe where there is limited capacity to adapt to changing climate. One approach that has been used to adapt to changing climate is in-field water harvesting for improved crop yields in the semi-...

Wetlands are major natural sources of greenhouse gases (GHGs). In central and southern Africa, one of the most extensive wetlands are dambos (seasonal wetlands) which occupy 20–25% of land area. However, there are very little data on GHG methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O)...

The IPNI sub-Saharan Africa Program has released an extension handbook for fertilizer management in smallholder farming in sub-Saharan Africa. The innovative handbook was developed as a resource for researchers, extension agents, agrodealers and other stakeholders working with smallholder farmers...

In many smallholder farming areas southern Africa, the cultivation of seasonal wetlands (dambos) represent an important adaptation to climate change. Frequent droughts and poor performance of rain-fed crops in upland fields have resulted in mounting pressure to cultivate dambos where both organic...
Optimizing a three-way pact comprising crop yields, fertility inputs and greenhouse gases may minimize the contribution of croplands to global warming. Fluxes of N2O, CO2 and CH4 from soil were measured under maize (Zea mays L.) grown using 0, 60 and 120 kg N hm-2 as NH4NO3-N and composted manure...
