Brief Summary

This study is an evaluation of the Global Alliance for Improved Nutrition (GAIN)'s Vegetables for All Project in Uganda. The aim of this program is to improve access to safe and fresh vegetables in FitFood Zones (FFZs) and generate demand for vegetables through a media campaign and FFZ branding. RTI and local partners will conduct impact and process evaluations of GAIN's program. 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.

Intervention

ACTIVE COMPARATOR

The Vegetables for All project will create FFZs in low-income urban and peri-urban areas. FFZs are the last mile/point of purchase for delivering a variety of fresh, safe, and accessible vegetables to BoP households. The program will link vendors and farmers through market facilitators, support the uptake of digital solutions for vendors to access vegetables, and support district governments to improve market infrastructure. To encourage BoP parents of children 3-9 years to buy and consume more vegetables, the program will include a demand generation component.

Behavioral: Food system and demand generation

Control/No Intervention

NO INTERVENTION

An equal number of geographic areas with similar levels of urban city to the intervention FFZs will serve as the control.
