  1. Healthy Kitchen Project in Inkawasi, Peru: Preliminary Results of Indoor Air Pollution Monitoring Lisa Büttner ETHOS 2007 January 26-28, 2007

  2. Healthy Kitchens Project (USAID-Winrock International) • Introduction of improved Inkawasina stove – modified Justa-style stove with locally-made “Rocket” elbow • Goal: 80% reduction in key pollutants responsible for health impacts ~ particularly of women and children ~ among 600 households from the district

  3. Location: Inkahuasi District • Department of Lambayeque • Ferreñafe Province • Villages: Uyurpampa, Tungula, Amusuy y Wasiqaj • Altitude: >3000 meters

  4. USAID-Winrock Project • Complementary aspects: • awareness raising of health impacts of IAP • formation of Environmental Health Committees • training of community promoters, entrepreneurs (potters, stove builders) • locally-appropriate micro-credit scheme • Team: • T.A. and oversight: Winrock • Field Implementation: NGO Centro ECO • IAP monitoring: Swisscontact • Spirometry: Dr. Jay Smith

  5. Results to Date Awareness, promotion, behavior change • EH Committees formed in 33 communities, comprising 3 EH Associations • 100+ volunteer promoters trained, using didactic materials • Daily radio spot for 1 month • 25 Healthy Kitchen competitions Micro-credit • 430 animal modules distributed • >150 repaid

  6. Results to Date Capacity building • 2 local potters, 21 stove builders trained • 2 Retained Heat Cooker workshops for 28 women and men; 4 RHCs raffled Technology • 315 stoves installed • First local kiln built, 15 elbows fired in Uyurpampa (municipal center)

  7. IAP Monitoring

  8. Sample • Across 4 communities in 2 district areas • > 5% of target households • Pre-intervention (Aug-Sept 2005): 48 • Post-intervention (Aug-Sept 2006): 44 • Note: didn’t monitor in rainy season ($, access)

  9. Monitoring of PM, CO Concentrations • Respirable particulates (PM4) • Pump & filter • 24-hour monitoring • 16 hr (5AM – 9PM, captures cooking times) • 8 hr (9PM – 5AM, period without cooking) • Carbon Monoxide (CO) • Real-time monitoring • Data logged in 1-minute intervals • Temperature • Data logged in 1-minute intervals • Instrument location: 1.3 m above floor, 1.3 m horizontal from fire/stove

  10. Survey • Household and kitchen characteristics • Size, ventilation, type of stove & fuel • Post-monitoring information • Cooking times, fuel • Exposure patterns of women and children

  11. Peru Environmental Air Quality Standards (“ECA”) DS 074-2001-PCM

  12. PM4: Pre-intervention Average: 680  868μg/m3 Maximum: 3,880 μg/m3 Minimum: 38 μg/m3 Swisscontact 2005

  13. CO (1hr) pre-interventionDaily pattern Swisscontact 2005

  14. CO 1hr vs. Nº meals cooked 2 meals 3 meals Swisscontact 2005

  15. PM4 24hr vs. Nº meals Swisscontact 2005

  16. PM4 vs. Roof Ventilation(pre-intervention) Swisscontact 2005

  17. Exposure: Women & Children HH where a woman was exposed HH where a child was exposed

  18. Installation of “Healthy Stoves” • August 2005 – August 2006 (still going) • In 26 households, stoves were installed in a new kitchen space

  19. PM4 en 24 hours (n=42) Reduction achieved in 30 kitchens (71%) Pre-intervention max: 3,380 μg/m3 Post-intervention max: 688 μg/m3 Swisscontact Janurary 2007

  20. Average 24-hr concentration of PM4 (n=42) 70% Swisscontact January 2007

  21. Average 24-hr concentration of PM4 (n=30) 84% Swisscontact January 2007

  22. Daily Pattern for CO (n=42) Swisscontact January 2007

  23. Average 1-hr maximum valuesfor CO (n=42) 60% Swisscontact January 2007

  24. Average 1-hr maximum valuesfor CO (n=30) 76% Swisscontact January 2007

  25. Daily Temperature Pattern Swisscontact January 2007

  26. Conclusions from Prelim Results • Overall intervention has significantly reduced PM and CO in the majority of hh • Goal of 80% reduction surpassed in over 70% • Cannot attribute reductions exclusively to stoves and behavior; new kitchen spaces may also have improved ventilation • Several contributing factors observed for cases of increased pollutants • Structural • Behavioral

  27. Next Steps • Implementation winding down by June 2007; emphasis on sustainability of micro-credit • More comprehensive analysis in 2007 • Follow-up on structural and behavioral modifications (Centro ECO, Winrock) • Follow-up IAP monitoring in August 2007 (Swisscontact) • Health symptom monitoring: additional data collection? • Huge potential for replicating successes, having large-scale impact on IAP and quality of life!

  28. Thank you!
