This paper is being inserted into the current debate on the topic of sustainability, as it applies to rural tourism. In particular, it addresses the need to identify strategic actions that will enhance the dissemination of cultural resources to facilitate cultural planning. Balancing the dynamic tension that characterizes the relationship between tourism development and protection of the landscape is key to finalizing appropriate planning strategies and actions, especially in the context of marginal rural areas. In support of theoretical and methodological reflections pertinent to this relationship, this paper presents a case study of the region of Marmilla on Italy's island of Sardinia. The absence of both a "cultural planning" philosophy and a strategic approach to systemic and sustainable rural tourism in this country has been acknowledged. This paper concludes by discussing the results that emerged during the preparation of this case study, with respect to smart, sustainable, rural tourism development, while accepting the need for compromises between the force of globalization, nature, tourism, places, and people.
