  1. Research Evidence from Conservation Agriculture (CA) Systems in Southern Africa – 2012/2013 By Christian Thierfelder In collaboration with: Amos Ngwira, Ivy Ligowe, Tonny Rocha Mwangala Sitali, Sephanie Cheesman, Tobias Charakupa, Gibson Manda, Walter Mupangwa, Herbert Chipara and Sign Phiri

  2. 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

  3. AT Direct seeder • Jab-planter • Dibble stick • Magoye ripper • Basin planting • Hoe-planter

  4. New Ideas for Africa....!

  5. 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

  6. Some Research Evidence... CA long-term trial at the Monze Farmer Training Centre, Zambia

  7. Regional perspective – CA vs CP in Southern Africa – 76% positive Source: Rusinamhodzi and Thierfelder, 2013 forthcoming

  8. Maize productivity on farmers’ fields in Zambia (Monze), 2006-2013

  9. Maize productivity on farmers’ fields in Zimbabwe (Zimuto), 2005-2013

  10. Maize productivity on farmers’ fields in Malawi (Lemu), 2005-2013

  11. Maize productivity on farmers fields in Malawi after 7-9 years of treatment

  12. Groundnut performance in Malawi, 2012/2013

  13. Infiltration is crucial in CA systems! Monze, Zambia Henderson, Zimbabwe

  14. Soil erosion 2005-2013, Henderson

  15. Soil moisture, 0-60cm, MFTC, 2012/2013

  16. Soil moisture, effect of cotton, 0-60cm, MFTC, 2012/2013

  17. Rainfall distribution in Lamego, Mozambique, 2012/2013 Total: 1017mm

  18. Maize response to CA at Lamego, 2012/2013

  19. Average maize grain yield in five target communities, Mozambique, 2008-2013

  20. Average cowpea grain yield in five target communities, Mozambique, 2010-2013

  21. Variety performance in five target communities, Mozambique, 2009-2013

  22. Yield comparison between different management strategies on maize in Mozambique 2008-2013

  23. Other Results from LT- and component trials in 2012/2013

  24. Maize Grain Yield at the Monze Farmer Training Centre 2012/2013

  25. Maize yield trends, rotation against sole crop, MFTC, 2006-2013

  26. Maize grain yield, sole maize, Henderson Research Station, 2012/2013

  27. Maize grain yield, maize rotation with sunnhemp, HRS, 2012/2013

  28. Harvest development over the last nine years, Henderson Research Station, 2005-2013

  29. Reductions in weed densities over time, Domboshawa Training Centre , Zimbabwe

  30. Change in weed composition over time – Domboshawa Training Centre, Zimbabwe

  31. Effects of Cover Crops on Maize Grain Yield,Domboshawa Training Centre, 2012/2013

  32. Effects of Cover Crops on Maize Grain Yield,UZ farm, 2012/2013

  33. Residue level trials – a never ending story....! University Farm, Zimbabwe a ab ab ab b c

  34. Economic viability in Malawi... Source: Ngwira et al., 2012

  35. 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

  36. Mozambique survey: What if 60% of farmers adopted CA – how long would it take? (n = 5,265)

  37. 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

  38. 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

  39. 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
