Assessment of vulnerability and site adaptive capacity to the risk of climate change: the case of Tchogha Zanbil World Heritage earthen site in Iran

Abstract

Purpose

The aim of this research is to evaluate the vulnerability of earthen heritage when facing climate change, by focusing on Tchogha Zanbil site as a case study – an outstanding example of an earthen site that recurrently faces extreme climatic events. Moreover, the adaptive capacity of traditional knowledge and ancient systems is also evaluated, in order to contribute for future climate change adaptation planning.

Design/methodology/approach

The vulnerability of cultural heritage to climate change was considered as the degree to which an identified cultural heritage value was susceptible to, or would be adversely affected by, the effects of climate change, including climate variability and extreme temperatures. In order to establish a vulnerability assessment, this paper will assess different definitions regarding vulnerability, exposure and sensitivity, crossing it with indicators of physical parameters, in order to propose an adaptive capacity for the site, based on ancient traditional knowledge.

Findings

Nonetheless, the entailed research helped establish a framework that contributes to outline the vulnerability and the potential for adaptive capacity of World Heritage properties, especially earthen sites located in regions exposed to rising climate change impact.

Research limitations/implications

The research faced some limitations regarding access to data and to site visits, due to COVID-19 restrictions that were in place.

Originality/value

This research presents a methodological assessment of climate change risk in Tchogha Zanbil, a World Heritage earthen site in Iran, representative of a property highly exposed to risk and vulnerability.
