DELIVER: increasing vegetable production and consumption in northern Nigeria
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
This project will try to see if working with small-scale farmers to increase vegetable production and promote consumption helps farmers and their neighbors eat more and a wider variety of vegetables.

What this trial studies
This evaluation uses a quasi-experimental design to compare vegetable quantity and diversity consumed by participating smallholder farmer households and neighboring non-farming households. The DELIVER program works with smallholder farmers to boost production, market linkages, and nutrition promotion while the evaluation measures household vegetable intake and diversity from 2024–2027. The evaluation is guided by the RE-AIM framework (reach, effectiveness, adoption, implementation, maintenance) and collects data from adult participants who speak English or Hausa within targeted Local Government Areas. Fieldwork is led by RTI International with local partners Datametrics Associates Ltd and Nigerian universities supporting implementation and data collection.
Who should consider this trial
Good fit: Ideal participants are adults (≥18) who are members of DELIVER smallholder farmer households or neighbor households recruited by those farmers, live in the targeted intervention LGA, speak English or Hausa, and can give informed consent.
Not a fit: People who live outside the targeted LGA, are not linked to a participating farmer, are under 18, or cannot communicate in English or Hausa are unlikely to receive direct benefits from this program.
Why it matters
Potential benefit: If successful, the program could increase how much and how many different vegetables households eat, improving dietary quality and nutrition in participating communities.
How similar studies have performed: Similar agriculture-to-nutrition programs in low- and middle-income countries have sometimes produced modest increases in diet diversity and vegetable intake, but results have been mixed and context-dependent, with limited rigorous evidence from northern Nigeria.
