Lessons Learned from the Evaluation of Helen Keller international’s Enhanced Homestead Food Production (EHFP) Program Presented by: Deanna Olney, PhD* October 19, 2016 * Olney, Dillon, Ruel, Nielsen. Lessons learned from the evaluation of Helen Keller International’s Enhanced Homestead Food Production Program. AOTR
Background • The agriculture sector can improve nutrition especially through integrated agriculture and nutrition programs. • Consistently improve agriculture production and dietary diversity (Leroy et al. 2008, Girard et al. 2012). • Also posited to improve nutrition outcomes by simultaneously addressing the direct and underlying causes of undernutrition (Ruel et al. 2013). • However, limited documented evidence exists about their impacts on nutrition outcomes and how impacts are achieved. • Rigorous, comprehensive evaluations that include impact and process evaluations are needed to generate this evidence.
Increase production Enhanced-Homestead Food Production (EHFP) program in Burkina Faso Establish Village Model Farms Provide agriculture training Provide nutrition and health- related training Establish home gardens Distribute agriculture and zoological inputs Program enhancements: • Targeted to mothers with children 3-12 mo of age • Increased focus on women • Improved behavior change communication (BCC) strategy Increase income & assets Increase consumption Improve nutrition, health and hygiene practices Improve maternal & child health & nutrition outcomes

How did the EHFP program work to improve children‘s and women’s nutritional status and women’s empowerment?
Production – consumption pathway: What worked? • Process evaluation • Improved knowledge of optimal agriculture practices and adoption of some key practices • Perceived increases in production of chickens, eggs and vegetables • Impact evaluation • Beneficiary women owned more chickens • Beneficiary women produced more micronutrient-rich foods
Production – consumption pathway: What needed improvement? • Process evaluation • Water constraints • HKI worked to decrease water constraints through a variety of methods such as creating new wells and boreholes, repairing existing water sources, using drip irrigation kits, etc. • Perceived inadequacies in supplies • Motivation and compensation of local implementers • Timing and duration of the program • Impact evaluation • Impact on household level production
Production – income pathway: What worked? • Process evaluation • Positive changes in men’s and women’s opinions about women’s ability to own and use land changed • Beneficiary women maintained control over their gardens, food produced and income generated • Impact evaluation • Beneficiary compared to non-beneficiary women: • Owned more agriculture assets • Owned more chickens • Produced more micronutrient-rich foods
Knowledge – adoption of optimal health and nutrition practices pathway: What worked? • Process evaluation • Knowledge of some optimal health, hygiene and nutrition practices improved • Impact evaluation • Knowledge and adoption of some key practices improved • Mothers’ intake of micronutrient-rich foods increased • Children’s dietary diversity increased
Knowledge – adoption of optimal health and nutrition practices pathway: What needed improvement? • Process evaluation • Home visit frequency • Motivation of local level program implementers • Technical abilities and quality of program implementation by OWLs • Understanding of BCC topics related to prevention and treatment of anemia • HKI retrained nutrition trainers and in turn beneficiaries in the topics related to the prevention and treatment of anemia • Impact evaluation • Further improvements in knowledge and adoption of some of the promoted practices
Conclusions • The EHFP program improved child and maternal nutritional status and maternal empowerment • Further reductions in anemia, diarrhea and stunting are needed • Possible ways to achieve this are: • Intervening earlier and for longer • Improving delivery and utilization of some program components • Re-examining issues related to motivation and compensation of program implementers • Including additional interventions designed to address some of the other causes of undernutrition such as water, sanitation and hygiene (WASH) interventions or the provision of a fortified complementary food for children 6-24 mo of age

Editor's Notes

  1. HC members more knowledgeable about anemia and more likely to elicit support from other family members to support adoption of optimal practices Beneficiaries in HC villages also tended to feel more supported in adopting new practices compared to those in OWL villages
