1. Introduction
Cultural heritage is increasingly imperiled by the multifaceted impacts of climate change. Phenomena such as rising sea levels, severe wildfires, floods, extreme rainfalls, increasing temperature and shifting weather patterns pose unprecedented risks to cultural landmarks that may result in complete deterioration of heritage sites. In some cases, the effects of climate change are irreversible, leading to the degradation of architectural structures, loss of biodiversity and damage to landscapes. Another aspect of this issue is climate-related migration. It is estimated that up to 187 million people may be forcibly displaced by two meters of sea level rise. In consequence, whole communities and even nations may be forced to abandon their lands which may lead to the vanishing of their cultural heritage and traditions.
This critical concern affects sites such as Rapa Nui (the indigenous name for Easter Island), the Chan Chan archeological zone in Peru and the area surrounding Edinburgh castle. As indicated by UNESCO, archaeological evidence embedded within the soil may be subject to accelerated degradation if the stratigraphic integrity of the soil is compromised as a result of factors such as enhanced flooding events, shifts in precipitation patterns or the thawing of permafrost. Additionally, as much as one third of the World Heritage cities are located in coastal areas, making them particularly vulnerable to risks associated with rising sea levels.
Although the importance of preserving monuments, buildings and sites of outstanding value to humanity has long been globally recognized, the intensifying impacts of climate change raise challenges to the traditional approaches to heritage protection. At first glance, international cultural heritage protection law, established mostly in a pre-climate crisis era, seems ill-suited to face these challenges. While instruments such as UNESCO Conventions provide a conceptual basis for global heritage protection, their static nature may limit their capacity to respond to the dynamic challenges posed by environmental transformations.
This concise essay seeks to analyze the principal international legal framework for the protection of cultural heritage, with the aim of evaluating the effectiveness of current legal measures in the context of climate change. It highlights the need for a more adaptive and forward-thinking approach to ensure the resilience of cultural heritage against climate-driven degradation. By exploring potential strategies, this analysis underscores the importance of integrating climate considerations into the global governance of cultural heritage.
2. Convention concerning the Protection of the World Cultural and Natural Heritage
The Convention concerning the Protection of the World Cultural and Natural Heritage adopted by UNESCO in 1972 (hereinafter referred to as the 1972 Convention) is a fundamental instrument aimed at protecting cultural and natural sites of outstanding value. The 1972 Convention recognizes the importance of preserving cultural and natural heritage for future generations. While the dominant focus of this instrument is on the protection of heritage sites from human-induced threats such as armed conflict, urbanization and tourism, its relevance in the context of climate change has gained increased attention in the last several years.
While the 1972 Convention itself does not explicitly address climate change, it contains mechanisms which can play a critical role in raising awareness and fostering international cooperation to mitigate climate risks. Pursuant to art. 11.4 of the 1972 Convention, the World Heritage Committee shall establish, keep up to date and publish the list of World Heritage in Danger, indicating World Heritage sites “for the conservation of which major operations are necessary.” This provision applies to sites that are “threatened by serious and specific dangers, such as the threat of disappearance caused by accelerated deterioration, large-scale public or private projects or rapid urban or tourist development projects; destruction caused by changes in the use or ownership of the land; major alterations due to unknown causes; abandonment for any reason whatsoever; the outbreak or the threat of an armed conflict; calamities and cataclysms; serious fires, earthquakes, landslides; volcanic eruptions; changes in water level, floods and tidal waves.” This implies that a significant number of climate change-related risks may provide a valid rationale for the inclusion of a heritage site on the list of World Heritage in Danger.
The recognition of sites on the List of World Heritage in Danger should not only raise global awareness but also mobilize the necessary financial resources and expertise for targeted conservation efforts. This process envisions the need for adaptive management strategies that integrate climate change projections into heritage protection plans. Furthermore, the Committee’s actions should encourage state parties to prioritize the protection of their cultural and natural heritage by adopting sustainable development practices that minimize climate risks.
However, it has been suggested that this legal mechanism has demonstrated limitations in its effectiveness and is not fully operational in addressing the complex and evolving challenges faced by vulnerable heritage sites. According to Flavia Z. Giustiniani, there appears to be a notable reluctance on the part of the World Heritage Committee to inscribe sites on the List of World Heritage in Danger, as illustrated by the Kathmandu Valley case in Nepal. This hesitation may stem from the political and diplomatic sensitivities involved, as such an action is often perceived as a critique of the state parties’ management of their heritage sites. Furthermore, the Committee seems cautious in utilizing the list as a tool to exert pressure or enforce compliance among state parties, reflecting a broader tension between the need for accountability and the desire to maintain cooperative international relations. This dynamic raises questions about the effectiveness of the List of World Heritage in Danger in fulfilling its intended purpose as a mechanism for ensuring robust protection of endangered cultural and natural heritage, including against risks resulting from climate change.
Ultimately, while the Convention provides a valuable legal framework for the protection of cultural and natural heritage, it requires ongoing adaptation to address the emerging and evolving threats posed by climate change. Strengthening the adaptive capacity of existing legal frameworks is essential, including more effective implementation of provisions within the 1972 Convention. This could involve incorporating explicit references to climate change into operational guidelines and promoting climate resilience in heritage management plans. Furthermore, fostering international cooperation through shared research, funding mechanisms, and technology transfer can enhance the collective capacity to address climate risks. Additionally, developing synergies between cultural heritage law and broader environmental treaties, such as the UN Paris Agreement, can create a more cohesive response to climate-induced challenges.
3. Convention for the Protection of Cultural Property in the Event of Armed Conflict
The Convention for the Protection of Cultural Property in the Event of Armed Conflict, adopted by UNESCO in 1954 (hereinafter referred to as the 1954 Convention) addresses the safeguarding of cultural heritage during armed conflicts. Its primary objective is to protect cultural property, including monuments, artworks and sites of historical importance, from destruction, theft, and other forms of damage resulting from hostilities. Despite the fact that the 1954 Convention, akin to the 1972 Convention, does not explicitly focus on environmental threats, its core provisions offer a framework for addressing the wider spectrum of risks to cultural heritage, including those associated with climate change.
Although the 1954 Convention does not contain provisions addressing climate change, its emphasis on the preservation and protection of cultural property could potentially be extended to include environmental challenges. This is particularly applicable to provisions that apply during peacetime, which focus on preventive measures to safeguard cultural heritage. Article 3 of the 1954 Convention obliges state parties to take measures for the protection of cultural property within their territory, even in the absence of an immediate threat of armed conflict. According to the Second Protocol to the 1954 Convention (hereinafter referred to as the Protocol), such measures include preparation of inventories, the planning of emergency measures for protection against fire or structural collapse, the preparation for the removal of movable cultural property or the provision for adequate in situ protection of such property, as well as the designation of competent authorities responsible for the safeguarding of cultural property.
The above mentioned measures, although designed for military conflict scenarios, can be adapted to address risks posed by climate change. For instance, the preparation of inventories and risk management plans, as outlined in the Protocol, can also encompass climate vulnerability assessments and adaptation strategies. Similarly, the enhanced protection mechanism encourages long-term planning and prioritization, which aligns with the need to safeguard heritage sites from gradual climate impacts. By fostering international cooperation and technical support, the Protocol provides a framework that can be interpreted in favour of promoting resilience against environmental threats, thus ensuring the enduring preservation of cultural heritage in a changing climate.
4. Conclusions
As climate change continues to pose significant risks to cultural heritage, there is an urgent need to adapt international legal frameworks to address these emerging threats. Existing legal instruments, such as the UNESCO Conventions, are predominantly concerned with safeguarding heritage from armed conflict and human-induced threats; however, their principles hold the potential to be broadened to address the evolving dangers associated with climate change.
One of the key strategies for adaptation lies in enhancing the preventive measures and risk management frameworks within these legal instruments. Incorporating climate change considerations into the operational guidelines of the 1972 Convention, for example, could strengthen the resilience of cultural heritage. The use of adaptive management techniques, informed by climate science, is essential for long-term preservation efforts. Additionally, fostering international cooperation and technical assistance can enable countries to share expertise, resources, and best practices for addressing climate risks to cultural heritage.
Despite its partial capacity to address climate-related concerns, cultural heritage law requires a more integrated approach that combines various legal disciplines. It has been indicated that a successful legal approach to combating climate change should integrate legal regulations concerning heritage protection, environment, property, construction, water, and planning. The adaptation of cultural heritage law to climate change requires an integrated, global approach that combines legal, scientific, and policy efforts. By enhancing existing frameworks and promoting international solidarity, we can ensure the continued preservation of cultural heritage for future generations, even in the face of climate crisis.
