One Acre Fund (OAF) cost effectiveness analysis


The Project

The One Acre Fund (OAF) works with farmers directly to improve household food production and nutritional status. The programme in Western Kenya addresses both poverty and malnutrition in targeted smallholder farming households. With funding from the Children’s Investment Fund (CIFF), OAF aims to improve dietary diversity of families, particularly among children and pregnant and lactating women by increasing household production and consumption of nutritious food, across OAF’s Kenyan farmer network.

To assess the impact of the nutrition programme, Kantar has been commissioned to conduct an evaluation study using a quasi-experimental approach to compare outcomes – household dietary diversity (HDD), women dietary diversity (WDD) and minimum acceptable diet (MAD) of children 6-23 months.  As part of the evaluation, LAMP is conducting a cost-effectiveness analysis of adding the Nutrition Programme to the Core Programme, from a programme perspective. The cost-effectiveness analysis will compare the  costs and benefits of the  nutrition  programme to costs and benefits of the core OAF programme to assess whether the additional benefits from the nutrition programme justifies its additional costs.

  • Findings expected to inform future programmes

Client Testimonial

LAMP were adaptive and flexible in the way they approached the study: responding to the needs of the programme and providing tailored and useful insights that informed the future of the work. In particular, LAMP were always forthcoming with insights they felt could be of immediate use to the programme – something that was very much appreciated as an implementer!
