Sustainability Analysis of Intervention Benefits: a Theory of Change Approach
Theories of change (ToCs) are models of how an intervention is expected to bring about desired changes in results of interest. Robust ToCs spell out the conditions under which the intervention should ‘work’, i.e., bring about or contribute to the desired results. But rarely does the ToC address issues of the future sustainability of the benefits from the intervention. We discuss how ToCs can adopt a sustainability lens and, along with the intervention, become sustainability-aware, by undertaking a sustainability analysis, exploring the sustainability of the various key ToC elements and seeking to identify and support sustainability mechanisms.
