Integrated agricultural research for development (IAR4D) from a theory of change perspective

Abstract

It is now more than a decade since integrated agricultural research for development (IAR4D) was proposed as a “new approach” or “set of good practices” for organising research to address complex problems of agricultural development, food security and poverty in sub-Saharan Africa.Since then, there have been efforts to investigate its impact in comparison to traditional research and development approaches. Although a growing number of publications are testifying to positive impacts of IAR4D and related agricultural research for development (AR4D) approaches, there has been limited explicit attention on its underpinning Theories of Change – the mechanisms or pathways by which it brings about impact. With the aim of contributing to a more robust grounding of the theory of change of IAR4D, this paper uses a comprehensive review of literature on IAR4D and related work experience of the authors in East and West Africa to critically engage with the implicit and explicit explanations and pathways for how and why IAR4D helps to achieve impact.This paper finds four emerging impact pathways focused on (1) market linkage, (2) social capital, (3) institutional change or (4) innovation capacity as critical mediating factors. Acknowledging articulation of each of these mediating pathways as encouraging progress, the article suggests putting these together in an integrated theory of change that also draws on established theories such as Multi-Level Perspective (Geels, 2005) and theory of adaptive change (Holling et al., 2002) to provide clear guidance and tools for designing and implementing effective AR4D interventions.
