Contributions to a revised definition of sustainable conservation

Abstract

The inclusion of Heritage in the global agenda for sustainable development has contributed to a broader discussion around the interconnection between heritage and sustainability. However, the definitions of both concepts lack consensus. In the last decade, hundreds of definitions of sustainability can be identified in the scientific literature. Often these definitions focus on different dimensions of sustainable development and do not cover the overlapping of social, economic and environmental aspects. The indicators vary according to the main goal and/or specific building under assessment. Moreover, the concept/notion of heritage is understood as a social process based upon definitions and values, which are dynamic and evolve. During the last decades, there is growing attention for the integration of such comprehensive concepts and several frameworks have been developed. However, a systematic definition of the relation between the two concepts is lacking. Some authors even pointed out that the multiple approaches, too specific for each context, lack objectivity and reduce credibility. The main goal of this paper is to contribute to a revised definition of sustainable conservation at the intersection of these two concepts, based on a narrative review of the recent literature and international reference documents, developed by different organisations, such as ICOMOS, the United Nations, and the International Organization for Standardization and the European Committee for Standardization.
