Improving Productivity of Rice under Water Scarcity in
Africa: The case for the System of Rice Intensification
Presentation by:
Prof. Bancy M. Mati
Jomo Kenyatta University of Agriculture & Technology
(JKUAT); Kenya
at the:
International Rice Development Conference and
Seminar on China-Africa Rice Development
Changsha, China
June 26 to 29, 2019
WATER SCARCITY IN AFRICA
It's more about economic water scarcity
than physical water scarcity
Africa Has Ample Water Resource Endowments
The water that Africa has, quantified
• Africa has about 4,000 cu km of
freshwater.
• There are 17 major rivers with
catchment areas > 100 000 km2
• There are 160 lakes > 27 km2
• Mean annual rainfall: 670 mm/yr
• Highly variable rainfall, from
<100 mm in deserts to more than
2,000 mm in rainforests & highlands
• Huge hydropower potential
of about 1,750 TWh (12% of
the global capacity)
• Vast groundwater resources
• The continent is surrounded by
three oceans: vast marine water
Africa when conditions are conducive…
Agricultural productivity supports sustainable livelihoods
5
But water is poorly distributed -- spatially & temporally

1906 - Improving Productivity of Rice under Water Scarcity in Africa: The Case for the System of Rice Intensification (SRI)

  • 1. Improving Productivity of Rice under Water Scarcity in Africa: The case for the System of Rice Intensification Presentation by: Prof. Bancy M. Mati Jomo Kenyatta University of Agriculture & Technology (JKUAT); Kenya at the: International Rice Development Conference and Seminar on China-Africa Rice Development Changsha, China June 26 to 29, 2019
  • 2. WATER SCARCITY IN AFRICA It's more about economic water scarcity than physical water scarcity
  • 3. Africa Has Ample Water Resource Endowments
  • 4. The water that Africa has, quantified • Africa has about 4,000 cu km of freshwater. • There are 17 major rivers with catchment areas > 100 000 km2 • There are 160 lakes > 27 km2 • Mean annual rainfall: 670 mm/yr • Highly variable rainfall, from <100 mm in deserts to more than 2,000 mm in rainforests & highlands • Huge hydropower potential of about 1,750 TWh (12% of the global capacity) • Vast groundwater resources • The continent is surrounded by three oceans: vast marine water
  • 5. Africa when conditions are conducive… Agricultural productivity supports sustainable livelihoods 5
  • 6. But water is poorly distributed -- spatially & temporally Map of Africa showing Rainfall excesses and deficits Source: UNEP, 2010 Deserts Big rivers
  • 7. • About 65% of Africa’s land area is comprised of drylands (annual rainfall 100-800 mm) • Rainfall is erratic, droughts, floods & high runoff losses • High runoff losses -- over 50% of rainfall is lost • High evaporation losses -- up to x 10 annual rainfall • Poorly distributed surface water resources (rivers, lakes) • Renewable water resources constitute only about 20% of total rainfall. Vast drylands, low rainfall, and water losses
  • 8. Groundwater resources remain un-mapped & untapped Source: WHYMAP (2008) Groundwater resources of the world.
  • 9. Africa is getting warmer: Climate Change is here! • Africa is warmer by 0.5°C than it was 100 years ago • The six warmest years recorded in Africa have occurred since 1987 • 7 droughts in 1980-1990 and then 10 droughts in 1991-2003 • Between 2000-2006, there were 60 weather- related disasters • Both floods and droughts have increased 9
  • 10. Climatic extremes are on the increase Flooding in Mozambique after Cyclone Kenneth, April 2019
  • 11. Climate Change is also Affecting Water Towers Satellite image comparing Mount Kilimanjaro’s glaciers between 1976 & 2006 • Since 1912, the ice caps on Mt. Kilimanjaro have decreased by between 50 to 80% Mt. Kilimanjaro glaciers in 1976 Mt. Kilimanjaro glaciers in 2006

  • 24. The System of Rice Intensification Responding with sustainable solutions to water scarcity
  • 25. What is the System of Rice Intensification (SRI)? • SRI is a set of practices that improves productivity of rice grown in paddies. • The SRI concept is based on the premise of “growing more rice with less water.“ • Moreoptimalpracticeswillproducebetter,more robustphenotypesfromagivengenotype 25
  • 26. 26 What SRI is Not • SRI is NOT a new type of rice. • It is NOT a new rice variety • SRI is not GMOs • It does not modify the genetic make-up of rice. • SRI is also NOT about growing upland rice varieties, although upland varieties can also benefit from SRI. • While rice is an aquatic plant, SRI has shown that rice crops do not have to be grown in continuously flooded paddies.
  • 27. Major Components of SRI Conventional flooded nursery SRI: younger seedlings, just 2 leaves 1. Raise seedlings in un-flooded nurseries, well-supplied with organic matter, 2. Transplant younger seedlings; i.e. at 8 to 12 days X SRI has seven major components (deviating from conventional flooded paddy)
  • 28. Early transplanting, at wider spacing under SRI Transplanting conventional Transplanting SRI young seedlings flooded paddy seedlings at wider spacing X 3. SRI involves transplanting only one seedling per hill (NOT in clumps of 3-5 seedlings), 4. Seedlings are transplanted at wider spacing in a square pattern • SRI uses less seed& farmers save up to 80% of the cost of seed
  • 29. Water management: SRI saves over 30% irrigation water 5. Alternate wetting and drying of the paddy field (do not continuously flood the soil) to ensure good aeration of the root zone
  • 30. Weeding is preferably mechanized under SRI practice Weeding SRI paddy with rotary weeder Women weeding conventional rice paddy 6. Weed control is preferably done with a simple mechanical rotary weeder. This aerates the soil as it eliminates weeds, improving root vigour and enhancing the life in the soil Rotary weeding saves up to 75% on labor costs compared to manual weeding X
  • 31. Organic fertilization under SRI 7. SRI utilizes organic manures or fertilizers to the extent possible; chemical fertilizer only when and where needed 6/28/19 31 More reliance on of organic manures saves on the costs of fertilizers; improves soil health and fertility
  • 32. Common practices for both conventional and SRI • Land preparation (tillage, rotavation, levelling) • Crop protection against pests and Diseases (preferably IPM) • Draining paddy at crop maturity • Harvesting • Post-harvest processing

  • 49. Why an SRI-Africa Network • The scientific basis for adoption of SRI has been proven in many countries in Africa, large published literature. • The main gap is knowledge flows -- upwards to reach policy makers, and laterally to reach more farmers and extension workers • Because… Africa is a continent fragmented by national boundaries, languages, geographic zones, and cultural differences • Technological divides between scientists and farmers, hence missed opportunities • There has been no one-stop-shop knowledge management platform for bringing together SRI community in Africa • Networks break these barriers and help establish human resource pools, for contacts, for specific needs/facilities
  • 50. SRI-AFRICA Knowledge Portal established at JKUAT Main Objective: Build a vibrant Africa-wide Community of Practice on SRI, for knowledge-sharing, advocacy and action -- create an African voice for SRI More specifically: a) Build SRI-Africa Network for peer support with a platform for learning and knowledge-sharing on SRI b) Gather, contribute to, share, and utilize knowledge and best practices on SRI to facilitate informed choices c) Resource mobilization to support SRI actions d) Implement programmes/projects & activities that lead to upscaling of SRI – including meetings, exchange visits, etc. e) Work towards establishing national SRI networks that can implement projects – first, develop national workshops which then culminate in an Africa-wide SRI network We have already developed a web portal for knowledge-sharing – credit to Cornell University (SRI-Rice) baseline database Website for knowledge-sharing: www.sri-africa.net
  • 51. 51 6/28/19 Taking SRI to the Next Level: Growing more rice with less water • Train extension workers to support SRI farmers • Innovative ways to encourage farmers to adopt SRI • Develop rotary weeders suited to local conditions and facilitate their availability • Conduct more research to assist informed choices • Create a value chain for SRI, e.g. branding • Expand SRI to all rice growing areas in Africa to grow more rice with less water! • Need to introduce hybrid rice under SRI – for Higher Yields = China-Africa collaboration.
