Rice Production
• Rice is the World’s most important staple
• Staple food of more than 3 billion people
• Produced in more than 130 countries
• Rice is usually grown for the domestic market (only 6% is grown for export)
• About 12 countries export rice while only 5 of them dominate world export

Rice Demand in Africa
• Staple food for many Africans• Since 1975 demand in Africa higher
than production in Africa• Africa imported 9.3 Mt in 2010
1/3 of the world market 40% of its own needs
• Rice demand in Africa is growing fastest in the world (6% per year)
![Page 8: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/8.jpg)
Rice Production Constraints in Africa
• Traditional production leads to low yields
• Overdependence on rain-fed systems
• Minimal use of external inputs
• Outdated varieties & poor seed quality
• Poor grain quality
• Insufficient policy support
• Lack of research and extension capacity

Not All Lowlands Are Suitable
• Fragile wetlands should be saved and not developed for agriculture
• Traditional uses like cultural ceremonies should continue
• Natural biodiversity can be utilized but not destroyed
• Environmental services need to be taken into account
![Page 14: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/14.jpg)
Cultural Ceremonies Should Continue

Land Tenure Conflicts
• State vs traditional ownership
• Land owner vs tenant
• Native vs immigrant
• Upstream vs downstream
![Page 17: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/17.jpg)
Effect of Climate Anomalies
• In Africa crop failure due to drought occurs already once every 5 years
• Incidence and severity of drought expected to worsen with climate change
• Rain-fed ecologies are most vulnerable
• Irrigated lowlands face increased water competition
![Page 18: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/18.jpg)
Low Labour Productivity
• Manual labour leads to:- Cultivating small plots- Late planting Late harvest Low yield- Bad leveling Uneven maturity - High harvest and post-harvest losses- Drudgery
![Page 19: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/19.jpg)

Land Tenure Conflict Management
• Multi-Stakeholder Processes- Include all stakeholders- Land users (gender!) - Land owners- Policy makers
• Negotiate long-term lease of land- Allow for investments- Ensure stability
![Page 21: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/21.jpg)
Improved Water Management
• Improved water control
• Water conservation- Bunded paddies- Contour bunds
• Water harvesting- Reservoirs- Micro-catchments
![Page 22: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/22.jpg)
Water Productivity
• Increase water productivity
• Develop low water-use systems
• Optimize water productivity of shared water bodies
![Page 23: Sustainable Intensification & Diversification of Rice-based Inland Valley Systems Paul Kiepe Regional Representative for East and Southern Africa Africa](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649efa5503460f94c0bd66/html5/thumbnails/23.jpg)
Small-Scale Mechanization
• Land preparation (one power tiller plows the equivalent of 90 able men)
• Threshing
• Transport - field to farm
- farm to market
• Milling

Importance for Tanzania
• Rice is the second most important crop in Tanzania
• 75% of rice is produced in rain-fed lowlands
• Productivity of rice is generally low
• Including vegetables will decrease undernourishment
• Vegetables will increase farm income

• Tanzania has to step up rice production because the world market runs out
• Rain-fed lowlands can largely supply enough rice for Tanzania and beyond
• Sufficient lowland area will remain intact for traditional and environmental uses
• Realization of sound water management can make rain-fed lowlands climate proof
