12106 Mali _ Styger SRI presentation for Cornell class IARD4020

  1. 1. The System of Rice Intensification (SRI) – Case study of Mali Erika Styger, PhD SRI-Rice, Cornell UniversityIARD 4020 – Agriculture in Developing Nations Cornell University, November 16, 2012
  2. 2. Importance of rice• Rice is staple for ½ of world population• Agriculture production needs to increase by 47% by 2050 to feed 9 million people (OECD, 2012)• Continuously flooded rice uses 2-3 times more water than other irrigated cereals(Bouman et al, 2007)• Rice paddies contribute to 20% of human Methane emissions (Yan et al, 2009)
  3. 3. World Rice Production 2010 2% 34% 31% 3% 25% 4%World Rice Production (2010), FAO, viewed 9th October, 2012. (by Chartsbin.com)
  4. 4. Total water use by country Water withdrawal for agricultural, industrial and municipal purposes by country, includes freshwater as well as groundwater extraction Source: FAO of the United Nations 2010, AQUASTAT online database, (by ChartsBin.com)Irrigated rice uses 1/4 – 1/3 of global fresh water withdrawal(Bouman et al, 2007)
  5. 5. Global methane emissions from rice fields Global Methane emissions from rice fields: 25 million tons/year Mitigation: •Through mid- season drainage, reduced by 4.1 Tg/y •Apply straw in off- season - 4.1 Tg/y, •both by - 7.6 Tg/yEstimated annual methane emission from global rice paddies at a spatial resolution of 5minXiaoyuan Yan et al (2009), Global Biogeochemical Cycles, Vol 23.
  6. 6. Our Challenges Improve agricultural productivity Improve food security Reduce povertyEnvironmentally sustainable practicesWithstand changing climate conditions Source page web: http://sririce.org
  7. 7. Climate-Smart Agriculture Triple Winhttp://www.fao.org/climatechange/climatesmart/en/Implemented through agro-ecological approaches:•Conservation agriculture•Agroforestry•System of Rice Intensification•others
  8. 8. What is SRI?• The System of Rice Intensification (SRI) is a methodology – For increasing the productivity of irrigated rice cultivation – By changing the management of plants, soil, water and nutrients, while reducing external inputs.• Developed in the 1980s in Madagascar by Father Henri de Laulanié Source page web: http://sririce.org
  9. 9. Main principles of SRI method1. Early, quick and healthy plant establishment1. Reduced plant density1. Organic matter enriched soils– keep soils aerated – favor soil microbial development1. Reduced and controlled water applications – through alternate wetting and drying water management
  10. 10. 6 Main Practices of SRI1. Single plant /hill2. Transplant young seedlings (2 leaf stage)3. Adopt wide spacing - planted in a grid4. Minimum water application during vegetative growth5. Assure soil aeration6. Use organic amendments as base fertilization
  11. 11. SRI practices induce a phenotypical change in riceSRI Conventional SRI Conventional SRI Conventional in IRAQ’s Al-Mishkhab Research Center, Najaf: SRI on left, Non-SRI on the right
  12. 12. Physiological and morphological changes of SRI plants• Tillers are thicker (+38%), Plants are higher (+24%)• More tillers/hill (+100%)• Greater canopy angle (33° vs 18°) SRI Non SRI Thakur, A.K et al (2011) Effects for rice plant morphology and physiology of water and associated mgt practices of SRI and their implications for crop performance, PAWE 9:13-

  14. 14. Yield performance• More/similar number of panicles/ m2• Longer panicles (20%)• More grains/panicle• Fewer empty grains• 1000 grain weight is heavier Non-SRI SRI ----- Increased Yields (often >50%)
  15. 15. Summary of Benefits • Yield Increase: often >50% • Water savings: 30-50% • Seed reduction: > 90% • Reduced cost/ha, income increase • Improved drought tolerance Mali Reduced chemical inputs • Less chemical fertilizer 20-40% (to 100% = organic SRI) • Improved tolerance towards pests and diseases – Pesticide reduction Sheath blight diseasehttp://sririce.org

  20. 20. 2007 - Year 1: Exploratory test• Africare, Timbuktu region• 1 farmer• Farmers from surrounding villages participate in a field visit• Farmers’ recommendations: To evaluate SRI at larger scale in 2008• Yield: SRI : 9 t/ha, Control: 6.7 t/ha
  21. 21. 2008 - Year 2: Adapting SRI practices• Africare and Government agriculture extension service• 60 farmers in 12 villages in the Timbuktu region
  22. 22. Objectives and approaches 2008• Adapt SRI principles to local conditions in Timbuktu• Communities take ownership of SRI evaluation through selected volunteer farmers• Close technical back-stopping, good data collection, develop locally adapted SRI manual• Side by side plot tests• Exchange visits: farmers representatives from Ministries, technical programs, donors etc
  23. 23. Irrigated Rice in the Timbuktu region Village Irrigation Perimeter 30-35 ha - 1 motor pump Shared among 100 farmers 0.33 ha / farmers

Scaling up SRI practices in zones where SRI is already known 2. Introducing SRI practices into new zones 3. Innovation development associated with SRI practices
  38. 38. 2009 - Year 3: Introducing SRI into new zonesMultiple partners at different levels: Africare (Better U Foundation), USAIDfunded project IICEM, Syngenta Foundation, National Research,National Extension Service, WBI videoconference, WB Ag project design• Timbuktu – 17 villages, 92 farmers – Africare, IICEM• Gao – 8 villages, 39 farmers – IICEM• Mopti – 6 villages, 44 farmers – IICEM, IER• Segou – 2 villages, 37 farmers – IER, Syngenta foundation• Sikasso – 3 villages, 10 farmers – IICEMTotal: 5 regions, 36 villages, 222 farmers
  39. 39. 2009 Year 3: Scaling up SRI practices Timbuktu region, Africare and Ministry of Agriculture• Focus on socio-organization of communities around SRI implementations• From 60 to 270 farmers (2008 to 2009)• From 12 to 21 villages in same region (improve area coverage)• Regroup SRI plots within irrigation area: for learning, for coordinated irrigation, weed management etc• Technical support reduced, more farmer-to-farmer learning• Focus on innovative ideas

  44. 44. SRI in 2010, 2011 and 2012 in Mali and beyond • In 2010: First National workshop on SRI in Mali • More than 50 well trained technicians in Mali • Funding and coordination problems • In 2011 (Year 5) – Irrigated Rice: 340 ha, 3250 farmers, average yields 8.4 t/ha, – Rainfed rice: 235 ha, 820 farmers, average yields 2.5 t/ha • Since 2010: Regional SRI trainings organized from Mali by IICEM project, NGO Africare, Regional Project E-ATP, Burkina): Benin, Burkina Faso, Ghana, Nigeria, Niger, Togo, Senegal.
  45. 45. SRI West Africa Initiative• July 2012 First West Africa Workshop: 13 ECOWAS countries to develop a West Africa SRI Network http://sri.ciifad.cornell.edu/news/featured08.html• Organized by National Center of Specialization on Rice, Mali (under World Bank WAAPP program), SRI-Rice Cornell University, CORAF/WECARD, Oxfam America• Proposal under development for World Bank WAAPP funding
  46. 46. Conclusions on Mali Case Study 1• Agro-ecological methods need to be developed in farmers’ fields• ‘Volunteer’ participation in the adoption and scaling up process is more sustainable (but less predictable)• Good technical back-stopping, data collection and reporting is essential for success
  47. 47. Conclusions on Mali Case Study II• Drawback: Development programs can often not respond well to bottom-up initiatives, are often too short term oriented, and output oriented• Funding becomes a big challenge• Coordination is necessary with growing number of stakeholders (needs funding)• Success depends also on leadership and individuals
