Importance and Utilization of Theory-Based Evaluations in the Context of Sustainable Development and Social-Ecological Systems
AbstractNumerous challenges confront the task of evaluating sustainable development—its complex nature, complementary evaluation criteria, and the difficulty of evaluation at the nexus of human and natural systems. Theory-based evaluation, drawn from critical realism, is well suited to this task. When constructing a program theory/theory of change for evaluating sustainable development, concepts of socioecological systems and coupled human and natural systems are useful. The chapter discusses four modes of inference and the application of different theory-based evaluation approaches. It introduces the CHANS (coupled human and natural systems) framework, a holistic, analytical framework that is useful in evaluating such complex, social-ecological systems and resonates with the challenging elements of sustainable development evaluation.
