Vegetables for All Evaluation Kenya

Overview

Global Alliance for Improved Nutrition (GAIN)'s "Vegetables for All" program in Kenya seeks to improve consumption of healthy foods by improving supply, increasing demand, and improving the enabling environment for different vegetables by operating at multiple levels - individuals, households, markets, producers, and policies. RTI and local partners propose to conduct impact and process evaluations of GAIN's program tailored to the theory of change. The evaluation will include a mix of quantitative and qualitative methods and will be guided by the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) evaluation framework.

Background: In urban and peri-urban areas in Kenya, Consumption of vegetables is low in bottom of pyramid (BoP) households, which earn \< 3.20 US dollars per person per day. To increase vegetable consumption in this population, GAIN will implement the Vegetables for All program, which aims to improve access to safe and fresh vegetables in Fit Food Zones (FFZs) and to generate demand for vegetables through a radio/television campaign and FFZ branding. The main retailers in the FFZ are mama mbogas (vegetable vendors), who will be linked to suppliers that are Good Agricultural Practices (GAP) compliant. Objective: The overall objectives of the evaluation are: 1) to assess the effectiveness of GAIN's Vegetables for All program for increasing the quantity of vegetables consumed and improving the diet quality of BoP consumers and 2) to conduct a process evaluation of GAIN's program that provides data to support findings of the impact evaluation. Methods: This study will use a mixed-methods quasi-experimental design in which 124 FFZs are assigned to intervention or control in Nairobi, Kiambu, Machakos, Mombasa, and Nakuru counties. The impacts will be assessed through cross-sectional population-based surveys of households with women 18-49 years who have a child 3-11 years in 62 intervention and 62 control FFZs at baseline and endline (N=1,364 at each time point). Mama mboga surveys will be conducted in all 124 sampled FFZs at baseline, midline, and endline (N=372 at each time point). Qualitative data will be collected at midline and endline. In-depth interviews (IDIs) will be conducted with vegetable value chain actors and other stakeholders (N=18 at each time point). Focus group discussions (FGDs) will be conducted with mama mbogas (20 FGDs at each time point) and household members (20 FGDs at each time point). The analysis will be performed using difference-in-difference estimation (surveys) and thematic content analysis methods (qualitative).
