  1. Too Many Beans? Exploring varietal choice in Rwanda Dorene Asare-Marfo Ekin Birol, Devesh Roy

  2. Presentation • Introduction/background • Study Design • Some Descriptives and Findings • Preliminary Model • Future Research

  3. Introduction • The Problem: • Relatively high prevalence of anemia (indicator of iron deficiency) in Rwanda: • 56% children 6 to 59 months • 33% women of child bearing age • 29% adult men • A solution: • HarvestPlus to introduce biofortified high iron beans in Rwanda to reduce iron-deficiency and improve diet quality.

  4. Study Objectives To investigate: • Current bean varietal adoption/diversification • Farmers’ preferences for various production and consumption traits • Farmers’ sources of information and seed • Household, market, agronomic etc. factors that affect varietal adoption … in order to inform effective, efficient and targeted delivery of high-iron biofortified beans

  5. Why Beans? • Second most popular crop grown – 86% of farmers (CIAT, 2004) • Highest per capita bean consumption in the world (CIAT, 2004) • “Meat” for the poor (CIAT, 1995) • 65% of national dietary protein (ISAR) • Eaten 5 times a week on average (NAS, 2008) • Important source of revenue with potential to become an important cash crop • 31% of households sold beans in 2004 (CIAT, 2008)

  6. Study Design Sampling • All 5 provinces • All 30 Districts • 77 sectors • ≈ 180 villages • 1321 households Ten Modules Two (three) cropping Seasons

  7. Some Household Characteristics

  8. Bean Cultivation – by region & type

  9. Own Consumption and Sales

  10. Role of Women in Bean Production

  11. Seed Acquisition - last season A

  12. Information Sources

  13. Top Ten Varieties

  14. Top Climbing Variety

  15. Top Bush Variety

  16. Importance of Production Traits (Top 3)

  17. Importance of Consumption Traits (Top 3)

  18. A Multivariate Probit Model for Varietal Adoption

  19. A few (general) implications • Strong local level networks suggest that conventional agents may not be appropriate for dissemination • target village heads and influential people within the village • Introduce a basket of biofortified beans: • Households grow multiple varieties and mix varieties • Differences across households in terms of valuation and motivation for growing specific varieties, e.g. higher marketing value versus consumption • Generally, no “star” variety – no strong market share dominance. Therefore less likely to get maximum adoption of ONE variety.

  20. Looking Ahead • Time to adoption (given a release date) • Rate of adoption (given a release date) Thanks!
