Environmental control strategies are commonly practised to limit biodeterioration issues threatening indoor cultural heritage objects, while they are still poorly exploited for the conservation of outdoor stone heritage surfaces, including rock art. In this study, we evaluated the environmental factors driving the diversity and abundance of lithobiontic communities in the Rock Engravings National Park of Naquane (UNESCO WHS n. 94, Italy). The survey considered 23 rocks that had been cleaned in the last three (3YC) or twelve (12YC) years or more than 40 years ago (NRC). A cyanobacteria-dominated biofilm and lichens (37 taxa) were the most widespread and abundant lithobiontic components, prevailing on 3YC–12YC and NRC rocks, respectively. On the latter, a turnover of xerophytic and meso-hygrophytic lichen communities was observed. On 3YC–12YC rocks lichen colonization, if present, was limited to nitrophytic species, including common epiphytes from surrounding trees and a small number of meso-hygrophytic species, with a prevalence of asexual reproductive strategies. Multivariate analyses including environmental parameters (canonical correspondence analyses) indicated that tree cover and the presence of bare or vegetated ground upstream of the rocks, probably prolonging wetness and providing nutrients by water transport, are the factors mostly related to the microbial and lichen recolonization of 3YC–12YC surfaces. On this basis, an experiment on preventive conservation was conducted, consisting of a new cleaning of a strongly recolonized 3YC surface combined with the building of a small wall to protect part of the rock from prolonged water fluxes. The fluorimetric and colorimetric monitoring of the rock surface, carried out 40 months after this new cleaning intervention, displayed recolonization on the unprotected area only, indicating the potential of preventive conservation strategies in outdoor environments.

The claim that the illicit trade in antiquities is the third largest, second only to arms and narcotics, is widely repeated. But where does this claim originate and what is the evidence for its veracity? The authors present a ‘stratigraphic excavation’ of the claim by systematically searching through academic articles, popular press and policy literature to reveal the factoid's use and reuse over the past five decades. The authors find that the claim is not based on any original research or statistics, and it does not originate with any competent authorities. The analysis demonstrates how the uncritical repetition of unsubstantiated ‘facts’ can undermine legitimate efforts to prevent looting, trafficking and illicit sale of antiquities.

This article considers the fiftieth anniversary of the 1972 United Nations Educational, Scientific and Cultural Organization’s (UNESCO) World Heritage Convention in light of climate change, offering a state of the field review of climate responses for World Heritage sites (WHS). Opening with a brief review of UNESCO World Heritage activities around climate change, we then detail the primary impacts and risks that climate change pose for WHS and the reporting and monitoring systems in place to document and track these impacts. Looking forward, we examine the most promising pathways for World Heritage to advance in the domains of climate mitigation, adaptation, climate communication, and climate action.

Maritime archaeology has been identified as a significant field among the humanities that could contribute to the global sustainable development agenda. This article explores the relevance of maritime archaeological studies to initiatives of climate action. Βy reviewing the contributions of various state-of-the-art projects and by linking their aims and outcomes to specific targets of the UN Sustainable Development Goals, the author highlights the benefits of involving maritime archaeological research in the pursuit of sustainability and climate resilience. This involvement could play a key role in reinforcing human-centred and culturally aware solutions to the current climate change effects that threaten human populations, especially in maritime regions. It is hoped that this discussion will inspire researchers in the humanities, archaeology, and maritime archaeology in particular, to use their expertise within the framework provided by the sustainable development agenda to help build a better future.

Climate change threatens archaeological sites and cultural landscapes globally. While to date, awareness and action around cultural heritage and climate change adaptation planning has focused on Europe and North America, in this article, the authors address adaptation policy and measures for heritage sites in low- and middle-income countries. Using a review of national adaptation plans, expert survey and five case studies, results show the varied climate change adaptation responses across four continents, their strengths and weaknesses, and the barriers to be addressed to ensure better integration of cultural heritage in climate change adaptation planning.

In conversation with playwright and theatre journalist Rina Vergano, multidisciplinary artist and musician Roxana Vilk unpicks her own experience of diaspora and the ways in which her cultural, familial and political roots have informed her artistic practice and inspired her current project about the power of lullabies.

In this paper we present dating of archaeological samples from Croatia only performed since our last reports (Obelić et al. 2011; Horvatinčić et al. 2012). Liquid scintillation radiometric measurement technique with benzene synthesis (LSC-B) and accelerator mass spectrometry (AMS) technique were applied.

This introductory article foregrounds the articles in this special issue, “Professional–Collector Collaboration: Global Challenges and Solutions,” complementing the special issue “Professional–Collector Collaboration Moving beyond Debate to Best Practice,” also published in Advances in Archaeological Practice. The articles that we introduce here cover examples and case studies from European settings such as Norway, the Czech Republic, England, Wales, Finland, and Belgium—places that have been exploring how to respond to the challenge of working meaningfully with collectors and finders of archaeological artifacts, especially metal detectorists. These are joined by examples from Australia, Mexico, Uruguay, and even the United States, in the context of handling—at first glance—problematic collections originating from elsewhere. The articles are diverse in their settings and the challenges they describe, but they point to the need for participatory and democratic approaches to archaeological heritage and the different publics that engage with it.

In the context of socio-economic transformation of Svalbard, from a place dominated by the coal mining industry to a nature-based tourism destination, the article focuses on how this transformation is co-created with material objects of coal mining remnants. These seemingly marginal, insignificant or even out-of-place remnants of coal mining activity (such as rusty barrels or collapsing infrastructure) have become, by law, a protected part of the Svalbard environment, a cultural heritage. Based on the relational (more-than-human) ethnography of guided tours, the analysis shows that this transformation is co-creating the characteristics of both the past of coal mining and the present notion of wilderness. It demonstrates the process not only as a transformation of interpretations, knowledge and values but also as a transformation of relations with non-human components of the environment. Rather contextual than linear shifts in a biography of the objects, together with the temporality of the objects and their porous character, play a significant role in the Svalbard’s transformation into a nature-based tourism destination.

This essay explores how the drafters of international humanitarian law (IHL) incorporated the past into their work between 1860 and 2020, and how they approached time, memory and history as indicators for this view of the past. Its sources consist of the complete series of general conventional and customary IHL instruments as well as the leading commentaries on them. For the IHL view of time, the impact of legal principles on the perception of time is scrutinized. Balancing nonretroactivity against customary international law and the humanity principle broadens the temporal scope towards the past, while balancing legal forgetting against imprescriptibility and State succession broadens it towards the future. For the IHL view of memory, dead persons and cultural heritage are seen as crucial vectors. Attention to the fate of the dead has been a constant hallmark of IHL, while care for cultural heritage has an even longer pedigree. For the IHL view of history, the essay highlights that the International Committee of the Red Cross has consistently advocated State duties to the war dead and has organized an archival infrastructure to satisfy the need – later converted into a right – of families and society to search for the historical truth about them.

Furthermore, the responses of IHL drafters to five major historical challenges are examined. First, while in the realm of war crimes impunity prevailed for most of history, after World War II a system of war crimes trials was mounted, culminating in the International Criminal Court. Second, soul-searching about the atrocities of World War II, including the Holocaust, helped create Geneva Convention IV of 1949, which protects civilians in wartime. Third, the human rights idea was not fully embraced by IHL treaty drafters until 1968. Fourth, the IHL approach to civil wars was slow and incomplete, but its appearance in 1949 and coming of age in 1977 were breakthroughs nevertheless. Fifth, colonial conflicts were not recognized as international wars in 1949, when this could have had considerable impact, but only in 1977, when decolonization was largely over. In all cases, the responses to these historical challenges came after long delays. Clearly, the IHL view of the past has to be assessed on a transgenerational scale.

Archaeological compliance is defined by state and federal legislation and the constrained, precise language in which it is written. Rules and policies operationalize the law but provide some flexibility in its interpretation and implementation. The pronounced use of “legal” and “scientific” language in archaeological compliance can be considered insensitive or offensive to some tribal members when discussing the disposition and care of the remains and belongings of their ancestors. The language we use constructs our reality and defines how we interpret our interactions of the lived experience. It is therefore necessary to revise the language employed in archaeological compliance to ensure that it reflects the values of the communities that these laws define to determine treatment and ultimate disposition of their ancestral remains and belongings. This article describes and encourages the use of a respectful terminology, developed in conjunction with compliance professionals and tribal representatives, to restructure the language we use and redefine our interactions as more considerate of tribal concerns for repatriation.
