Lybbert - SRI

  1. 1. Improving Rice Productivity to Increase Rural Incomes and Food Security in Haiti Travis J. Lybbert, Professor, Agricultural & Resource Economics, UC Davis Abbie Turiansky, Researcher, Mathematica Policy Research Haiti Priorise – 2 May 2017
  2. 2. Stubbornly Low Rice Productivity Hurts • Rice yields in Haiti have experienced little growth in the past 50 years • Consequently, Haiti now imports 80% of the rice it consumes • Yield gains in recent years are encouraging but insufficient
  3. 3. Stubbornly Low Rice Productivity Hurts • Haiti is one of the most food insecure countries in the world • 50%+ of Haitians are undernourished • Average calorie consumption is 20% below recommended levels • Hunger and food insecurity abound even in the Artibonite ‘rice basket’
  4. 4. Stubbornly Low Rice Productivity Hurts • Stagnant and low rice productivity hurts both producers and consumers • Direct harm to subsistence and other farmers • Indirect damage inflicted on the broader rice value chain • Compromised resilience to production shocks
  5. 5. Analyzed Solution Improved Rice Production Practices in the Artibonite: System of Rice Intensification & Amelioration (SRI-A)
  6. 6. Improved Practices: SRI-A in the Artibonite Scalable intervention based on Oxfam America program, 2012-16 1. SRI demonstration plots 2. SRI-A training program 3. Technical support 4. Coordinated by bloc irrigation assoc. 5. Agricultural credit expansion 6. Cleaning canals and drains 7. Incentives to rototiller service providers
  7. 7. SRI-A Costs • Costs and benefits based on RCT with design changes • External implementation costs • Association support for demos, training, and technical support • Credit incentives • Canal cleaning support • External support fades by year 7 • Private production costs • Improved practices demand more labor, land prep, and other inputs • Learning reduces costs by 5% annually • Heterogeneity in added costs implies important profit heterogeneity 0 2 4 6 8 10 12 14 16 1 2 3 4 5 6 7 Costs(MillionUSD) Year of Intervention Total Private and External Costs Total added private costs Total external costs 0 50 100 150 200 250 300 350 400 450 500 1 2 3 4 5 6 7 Costs(USD/hectare) Year of Intervention Projected Additional Private Production Costs Labor Land preparation Fertilizer Harvest, milling, transportation
  8. 8. SRI-A Benefits • 14% initial yield gain from mix of SRI and SRA practices • Baseline yield assumed 5T/ha • SRI-A adoption increases over time (extensive margin) • 5% annual increase in yield gain due to learning (intensive margin) • Yield gain valued at $236/T (median market price for rice) 0% 5% 10% 15% 20% 25% 30% 35% 40% 1 2 3 4 5 6 7 PercentYieldGain Year of Intervention Projected Yield Gains from SRI-A Intervention Extensive yield gain Intensive yield gain (learning) 0 0.2 0.4 0.6 0.8 1 1 2 3 4 5 6 7 ShareofRiceLand Year of Intervention SRI-A Adoption Assumptions Share in SRI Share in SRA
  9. 9. Summary of BCR, Scenarios & Limitations • Benchmark BCR: 0.76 • Optimistic yet conceivable scenarios, including very optimistic “best case” • Limitations • SRI benefits beyond average yield not included • Local market and value chain effects of 235,600MT more locally-produced rice? • Canal cleaning or expanded credit alone may have BCR>1 • Some may profit significantly from SRI-A • Targeting these farmers precisely would increase BCRs • Important to ensure that farmers can self-select into optimal production practices 0 0.2 0.4 0.6 0.8 1 1.2 Benchmark 30% SRI Price Premium 30% Lower External Cost Mechanical Weeder, 50% Lower Weeding Labor Enhanced Learning, 10% Annual Efficiency Gains "Best Case" BCR Benefit Cost Ratios by Scenario 3% 5% 12%
