Abstract
While a wide consensus acknowledges that participation is critical for the successful implementation of change that improves the livelihoods of people and communities around the world, justly securing that participation from stakeholders (at both the design and implementation stages) remains a demanding problem. This paper proposes a heuristic model for increasing participation that not only helps to investigate instances of nonparticipation but also opens up alternative intervention strategies and pathways for designers and implementers to consider toward more justly increasing participation and overcoming nonparticipation. Applied to a successful case of participation in Gurúè District, Mozambique-where an 89% solution adoption of an improved postharvest seed storage method was measured two years after initial training-this paper demonstrates the key importance of designing opportunities and motivations for participation into any solutions or innovations but especially justice as a factor for successful realization of theory of change efforts (all the more so in developing nation contexts). Applied to a second case study, this paper also explores participation despite little to no motivation to do so. Aiming to afford designers and implementers of theory of change interventions a tool for more successfully and exactly matching innovation goals with innovation outcomes, the paper also addresses broader implications for the model within theory of change approaches generally.
