About this study
Official title: Evaluation of the Global Alliance for Improved Nutrition (GAIN) DEcent LIVelihoods for Small-scale Producers Delivered Through Economic & Resilient Food Systems (DELIVER) Project in Nigeria
The DEcent LIVelihoods for small-scale producers delivered through Economic \& Resilient food systems in Nigeria (DELIVER) (2024-2027) project is designed to address the low per capita consumption of vegetables and variety of vegetable consumption in northern Nigeria by working with smallholder farmers to increase production and promoting healthier diets through greater vegetable consumption among farmers and their neighbors. The objective of this evaluation is to assess the effectiveness of GAIN's DELIVER program for increasing the quantity and variety of vegetables consumed by smallholder farmer households participating in the program and by neighbor households. This evaluation will use a quasi-experimental design to assess the impact of GAIN's DELIVER programs on the quantity and diversity of vegetables consumed by smallholder farmers and non-farming neighbor households. The evaluation will be guided by the RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework. RE-AIM is a framework that is useful for evaluating the program impact of multifaceted and multilevel interventions.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Consumption of vegetablesBehavioural
DELIVER is designed to address challenges of low consumption of vegetables in both variety and quantity by working with smallholder farmers to increase production and promoting healthier diets through greater vegetable consumption. The project will build the capacity of smallholder farmers in vegetable production through collaborating with lead farmers to establish demonstration plots that showcase advanced agricultural techniques and technologies. These plots will serve as training hubs for other farmers in vegetable production, postharvest handling, as well as business and market planning. DELIVER aims to increase consumption among neighbors of the smallholder farmers by asking the farmers to recruit at least one neighbor family to whom they will regularly sell vegetables. The project also includes a livelihood component that will increase market connections and access to finance for smallholder farmers.

- This evaluation will use a quasi-experimental design to assess the impact of GAIN's DELIVER program on the quantity and diversity of vegetables consumed by smallholder farmers and neighbor households. Smallholder farmers and neighbor households will be randomly selected from lists compiled by GAIN in 4 program LGAs (2 in Kano, 2 in Kaduna). The household-level impacts of the intervention will be assessed through panel surveys in intervention LGAs at baseline and endline in two groups: (1) new smallholder farmers and (2) neighbors who are not involved in the vegetable gardening project.
