ABSTRACT
Cost-Effectiveness Analysis (CEA) is a decision-support tool that allows strategy comparisons without the need for monetising expected outcomes. Since benefits to be gained in heritage contexts are inherently difficult to price, a CEA may provide valuable support to the allocation of cultural heritage preservation resources. Nevertheless, its application in the heritage sector is still limited, arguably due to difficulties in ‘effectiveness’ appraisals. STORM (Safeguarding Cultural Heritage through Technical and Organisational Resources Management) is an H2020-funded project for the development of Disaster Risk Management solutions for heritage sites facing natural hazards and climate change. Within its scope, a methodology for the CEA of conservation interventions was developed and applied to the Roman Ruins of Tróia (Portugal) pilot site. This paper describes the CEA methodology, including cost and effectiveness indicators and discount rate; and reports its application for the assessment of five strategies addressing the risks of a sand dune weighing upon a Roman well. Using expert opinion to tackle the effectiveness appraisals, the CEA showed that ordinary maintenance options are costlier but more effective than extraordinary maintenance ones. The most cost-effective option was the less intrusive strategy, matching current perspectives on archaeological conservation, and seemingly indicating that the procedure is robust.
