2. Contents
• Tillage in SSA
• CA mechanization options
• Development of the CA equipment industry
– Brazil
– East Africa
– Southern Africa
• Contrast between Brazil and SSA
• Guidelines for development of the industry
• Conclusions
4. Farmers’ perceived advantages
of soil tillage
• Weed control
• Mobilization of nutrients
• Smooth seed bed
• Elimination of compaction
• Incorporation of amendments
• Control of pests and diseases
• Control of runoff and accumulation of
water
5. BUT: damage caused by hoes and
ploughs soon becomes evident
• SOM is oxidized
• Physical, chemical and biological
degradation of the soil
– Hard pans
– Crusting
– Erosion
• Yields decline leading to abandonment
and hunger
6. CA is an answer. BUT there are
widely discussed problems:
•Maintenance of organic soil cover
•Crop ‒ livestock competition
•Weed control
•Pest control
There is, however, little information
on the problems of developing a
viable CA machinery manufacturing
sector

8. CA mechanization options for
smallholder farmers in SSA
1. Removal of
hardpans and
increasing water
infiltration
10. CA mechanization options for
smallholder farmers in SSA
3. Weed control
• Mechanical: surface
scraping, hand
pulling, knife rolling
• Biological: mulch,
cover crops, rotations
and associations
• Herbicides: sprayers
and applicators

2. East Africa, in its infancy
• Uganda (AEATRI)
• Kenya & Tanzania
(training in S America
with FAO)
• Nandra and
Intermech
14. Training East Africans in S.

15. Intermech and Nandra are now
market leaders
• Nandra, Moshi
• Intermech, Morogoro
17. Development of the CA machinery industry
3. Southern Africa (i), just awakening
• 1980s RTZ (later Hastt) in Zimbabwe
• 1990s GTZ/BMZ contill
project, Zimbabwe
• 1990s CFU and GART, Zambia.
(Chaka hoe, Magoye ripper, Palabana
subsoiler and planter)
• 2010 GART planter
18. Development of the CA machinery industry
3. Southern Africa (ii), moving forward
2000s: innovation networks (manufacturers,
researchers, farmers) create new products and
new approaches

25. Conclusions
• SSA CA equipment manufacturing
industry is in its infancy and needs
nurturing
• Need local adaptation. Import is OK in
the short term
• National governments must address
the creation of an enabling
environment. Signs are encouraging
