How irrigation supports nutrition outcomes- New Insights from the USAID Feed-the-Future Small-Scale Irrigation project

  1. 1. How irrigation supports nutrition outcomes: New Insights from the USAID Feed-the-Future Small-Scale Irrigation project Claudia Ringler, IFPRI Stockholm, August 27, 2019
  2. 2. SMALL SCALE, FARMER LED IRRIGATION Characteristics • Self-provisioned access to water • Range of technologies • Individual, household or group scale • Multiple sources of water • Lack formal governance for water sources • Supplemental and dry season irrigation • Multiple uses (livestock, domestic) • Often high value crops
  3. 3. IRRIGATION: DIETARY DIVERSITY AND NUTRITION OUTCOMES ETHIOPIA & TANZANIA • Both climate and idiosyncratic shocks have negative impacts on dietary diversity and child nutrition in ETH and TAN • Ethiopia: No statistically significant effects of irrigation on women’s dietary diversity score (WDDS) and household dietary diversity score (HDDS); but lower childhood wasting in households that experienced at least one drought shock over the past 5 years • Tanzania: Irrigation leads to higher WDDS and higher HDDS among households that reported drought shock in past 5 years
  4. 4. • Women consume low levels of nutrient-dense food groups: eggs, dairy, dark-green leafy vegetables, meat, fish and poultry with high seasonal variability: low dietary diversity score: 3-4 food groups out of 10 (Minimum Dietary Diversity-Women—MDDW), with seasonal variation (longitudinal survey) • High seasonality of energy, protein, vitamin C, calcium, iron and zinc intakes • Women in irrigating households more likely to meet MDDW, and higher energy and calcium intake than women from non-irrigating households across all three survey rounds • No malaria observed for SSI in survey sites IRRIGATION: IMPACTS ON WOMEN’S DIETS IN ETHIOPIA
  5. 5. IRRIGATION-NUTRITION LINKAGES: EVIDENCE FROM NORTHERN GHANA
  6. 6. • Assess the WASH pathway for nutrition for irrigators and non- irrigators • Assess children’s outcomes in the longitudinal survey • Collect new data that link irrigation with HWISE, rather than WASH • Add cross-sectoral communication tools to irrigation interventions to assess benefits IRRIGATION-NUTRITION LINKAGES: NEXT STEPS
