1. Adoption of Maize Technologies in East Africa What Happened to Africa’s Emerging Maize Revolution? Hugo De Groote, Cheryl Doss, Stephen D. Lyimo and Wilfred Mwangi
Presentation for the FASID Forum V, “Green Revolution in Asia and its Transferability to Africa”, Tokyo, December 8-10, 2002
2. The Problem 1997: “The Emerging Maize Revolution in Africa” indicated that research and extension resulted in
Development of new technologies
Adoption of those technologies
Increased food production for Africa
3. And maize production in Africa: increased indeed
4. But: maize production per person decreased
5. What is so important about maize in Africa? Maize is the most important food crop in East Africa
Maize is most likely to respond to new technologies:
Hybrid
Fertilizer
Maize is most likely to benefit from private sector involvement
Maize is more interesting to the urban consumer
6. In this presentation Adoption of maize technologies in East Africa
Kenya
Tanzania
Ethiopia
Based on:
Literature and secondary data
Seed production and sales data
22 adoption studies
7. Maize in East and Central Africa
8. Evolution of Maize in East Africa
9. Maize in Kenya, 1960-2000 Maize breeding program started in 1950s
Hybrids for the high-potential areas very successful
Research and seed production by state, linked
1990s:
liberalization, new companies enter
Many new varieties, not succesful
1 hybrid = 50% of sales (from 1976/1986)
Fertilizer market, agribusiness liberalized
2002: Kenya Seed Company privatized, still dominates
10. Maize in Kenya, 1960-2000
11. Evolution of adoption in Kenya
12. Kenya: agroecological zones
13. Kenya: seed sales and production
14. Adoption studies
15. Tanzania First maize breeding program in 1960, 2 popular OPVs were released
Second program launched in 1974:
15 OPVs and hybrids
5 state foundation seed farms,
1 state-owned certified seed company: TANSEED
mid 1990s: liberalization of seed sector
At least 5 companies active, mostly
16. Maize in Tanzania, 1960-2000
17. Seed Sales - Tanzania Improved seed sales in 2000: 7.75 tons
Negative trend
At seed rate of 15 kg/ha = 517,000 ha
Area in improved seed = 26% (ignoring recycling)
18. Adoption of improved seed and fertilizer - Tanzania
19. Factors influencing adoption - Tanzania
20. Ethiopia Background
Feudal system until 1974
Marxist/military regime until 1991
Since: more liberal and, but still waiting for elections
Maize system
Strong research and extension program
1993: Sasakawa 2000 extension package (maize seed, fertilizer and credit, based on demonstration plots
1995: national extension system takes over – massive
Yield almost doubles, but prices in 2001 drop by 2/3
Demand for improved seed in 2002 very low
21. Ethiopia – Maize evolution
22. Adoption of Improved Maize Varieties - Ethiopia 2001: 7,700 tons, at 25 kg/ha = 307,000 ha
Area in improve maize varieties = 307,000 ha or 21%
Price decrease from 1999/2000 to 2001: by 2/3
23. Factors influencing adoption - Ethiopia
24. Fertilizer adoption
25. Conclusions - Methodological need for:
time series data on seed and fertilizer:
Production
sales
prices
better definitions, clear concepts
Logit analysis not very promising, rather:
institutional analysis
Policy analysis
Historic analysis
26. Conclusions – Green Revolution Farmers adopt improved varieties and fertilizer when economical
Institutions are important:
National research programs
Extension
Credit
Price policy
