Abstract
Tourism interventions, as tools for social change and preservation of natural and cultural assets are inherently complex. This study presents an improved method for the evaluation of complex tourism interventions. We argue that participatory methods can promote a culture of evaluation that supports partners throughout evidencing project impacts, eliminating negative attitudes to evaluation resulting from fear of being judged on performance. We demonstrate that Theory of Change (ToC) is an effective tool that allows organisations to actively co-create and own an evaluation strategy to ensure the delivery of project outcomes. We show how ToC can be applied as a useful process and impact evaluation tool. This paper represents a novel methodological application of ToC based on participatory approaches to evaluation to disseminate knowledge and to improve decision-making in the field of tourism interventions and tourism policy making.
