Intervention model description: 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.
Primary purpose: OTHER

Brief summary: 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.
