Research sites in Southern Africa • Major target countries, Malawi, Mozambique, Zambia and Zimbabwe • Adaptive research of CA in +/-53 target communities • Strategic research on 11 research locations and 9 long-term trials • Long-term data series of up to 9 years available
AT Direct seeder • Jab-planter • Dibble stick • Magoye ripper • Basin planting • Hoe-planter
Partnerships Farmers NARES of all target countries NGO‘s and other development agents International Agriculture Research Centres Advanced Research Institutes Private sector Innovation platform meeting - Zambia
Some Research Evidence... CA long-term trial at the Monze Farmer Training Centre, Zambia

Results of a multinomial logit model looking at adoption of CA packages in Malawi (n=276) NOTE: CA Tech 1 = full CA adoption; CA tech 2 = adoption of two principles; CA tech 3 = adoption of no-tillage/minimum tillage
Mozambique survey: What if 60% of farmers adopted CA – how long would it take? (n = 5,265)
Current Research Avenues by CIMMYT -Socio-economic research Better understanding of farmer‘s decision making Constraints to the adoption (adoption studies, value chain analyses etc.) Economic quantification of CA systems Capturing the extend of adoption Documentation of lessons learned
Bio-physcial research Crop livestock interaction (residues, fodder etc.) Integration of several climate smart technologies Effects and integration of green manures into rotation systems (relay cropping, intercropping, strip cropping, full rotations, double-legume system) Weed control strategies involving biological and chemical methods Rotations with different green manure cover crops in CA
Bio-physcial research contd..... Maize variety trials under different cropping systems Nematode and other pest and disease screening trials Long-term CA systems trials Modelling and decision support systems Farmer demonstration Plot in Malawi
