ABSTRACTEnvironmental catastrophes represent profound challenges faced by societiestoday. Numerous scholars in the climate sciences and the humanities haveargued for a greater ethical engagement with these pressing issues. At thesame time, several disciplines concerned with hazards are moving towardsformalized ethical codes or promises that not only guide the dissemination ofdata but oblige scientists to relate to fundamentally political issues. Thisarticle couples a survey of the recent environmental ethics literature withtwo case studies of how past natural hazards have affected vulnerablesocieties in Europe’s prehistory. We ask whether cases of past calamitiesand their societal effects should play a greater role in public debates andwhether archaeologists working with past environmental hazards should bemore outspoken in their ethical considerations. We offer no firm answers, butsuggest that archaeologists engage with debates in human–environmentrelations at this interface between politics, public affairs and science.

We are living in a climate of fear about our future climate. The language of the public discourse aroundglobal warming routinely uses a repertoire which includes words such as ‘catastrophe’, ‘terror’, ‘danger’,‘extinction’ and ‘collapse’. To help make sense of this phenomenon the story of the complex relationshipsbetween climates and cultures in different times and in different places is in urgent need of telling. If wecan understand from the past something of this complex interweaving of our ideas of climate with theirphysical and cultural settings we may be better placed to prepare for different configurations of thisrelationship in the future. Mike Hulme (2008, 5)

Introduction

With these words, Professor of Climate and Culture at King’s College London Mike Hulme chose toopen his clarion call for a culturally aware and historically informed appreciation of our currentclimate change challenges (see also Hulme 2010, 2011b, 2015). He has further argued – in theinaugural issue of Nature Climate Change – that the humanities have a major role to play in meetingthese challenges in the years to come (Hulme 2011a). Although no claim to comprehensiveness wasmade, archaeology was conspicuously absent in the list of pertinent subjects offered by Hulme.Archaeology or its long-term perspective go similarly unmentioned in major recent reviews ofenvironmental ethics (e.g. Palmer, McShane, and Sandler 2014; Nolt 2015). Despite its strong

tradition of collaboration with the environmental sciences (e.g. Butzer 1982; Dincauze 2000;Kristiansen 2002), does archaeology really have nothing to contribute here?

The present article discusses how archaeology can relate to contemporary environmentalethical debates, and what their implications may be for archaeological practice. It does sospecifically in the context of emerging discourses in neighbouring disciplines – climate changescience, geology, disaster risk reduction, the environmental humanities – about personal andprofessional codes of behaviour that would to a certain degree prescribe conduct where notionsof stewardship, preservation and professionalism increasingly spill over into political domains. This,we believe, is particularly pertinent when past human–environment relations are also viewedwithin the context of our inherently future-oriented heritage (Holtorf and Högberg 2015). Webriefly discuss two case studies of how environmental events – specifically volcanic eruptions –have strongly affected European communities in the past. Each is associated with considerableacademic controversy, but also with results that are suggestive and ‘usable’ (Stump 2013) if seen inthe light of current affairs and future risks. The question is therefore whether those working withissues of environmental impacts in the past should – or rather must – engage with the implicationsthat their research has for potential futures.

We begin by outlining the theoretical and intellectual background for a possible resolution, inour perception of an interesting, albeit not entirely unproblematic, convergence of differentdisciplines within both the humanities and the natural sciences. We then introduce our casestudies and discuss their implications for disaster risk management. While we strongly promotean ethical engagement by archaeologists with the potential consequences of their research, inconclusion we also caution against the conscious downplaying of uncertainty in the pursuit ofenvironmental activism. Far preferable, we feel, is the careful consideration of how research resultsare communicated, and to which targeted channels they are primarily directed.

Environmental ethics and disciplinary promises

Ethical thinking is generally divided into three more or less distinct approaches: virtue ethicsfocusing on morality and character; deontology with its focus on rules; and the utilitarianconsequentialism concerned primarily with consequences of action. All ethics share a concernwith the ‘right’ way of acting. Climate change and climate catastrophe are ubiquitous issues in thepresent, and there are no obviously right solutions. Instead, coping with the environmental andsocietal transformations brought about by climate change is a so-called ‘wicked problem’ (Hulme2009) that, by definition, has no single correct means of resolution, but which has to be met byinherently value-laden assessments. For Hulme (2014), the solution is the reinvigoration of virtueethics that lead us to take personal and, by extension, professional standpoints on the matter.Virtue ethics has a venerable history of thought going back to Aristotle, and has previously seenapplications in professions such as medicine and legal practice (Oakley and Cocking 2001).Recently, virtue ethics has also experienced a revival within the broader field of environmentalethics (Cafaro 2010; Palmer, McShane, and Sandler 2014).

Within the non-archaeological humanities, a concern for environmental issues is also growingrapidly. Eco-historicism or environmental history (Wood 2008) as well as eco-criticism or theenvironmental study of literature (Buell 2011; Marland 2013; Hiltner 2015) together make up thefield of environmental humanities (Bergthaller et al. 2014). Writings in this genre – going back tofounding contributions such as Rachel Carson’s Silent Spring (1962) and Aldo Leopold’s A SandCounty Almanac (1949) – have strong ethical dimensions verging on activism (e.g. Plumwood 2002;

Skrimshire 2010). Most recently, Kate Rigby (2009) has presented a strong argument for environ-mental ethical engagement from the humanities specifically in relation to disasters (Rigby 2015).Her ethical stance can be located somewhere between virtue ethics and the moral imperatives ofdeontology.

Within the field of disaster risk reduction (DRR), renewed attention to ethical principles hasemerged from a different direction. Working with human subjects in disaster and post-disastersettings, DRR research usually has to pass ethical approval before funding is given and investigationsbegun. Most commonly, the ethical integrity of projects is judged against benchmark documentssuch as the Belmont Report (see http://www.hhs.gov/ohrp/humansubjects/guidance/belmont.html),which represents a mixture of deontological and consequentialist thinking. More specifically, thesebaseline ethics have recently been expanded by a more pluralist approach emphasizing fidelity,reparation, gratitude, justice, beneficence, self-improvement and non-maleficence as cornerstones ofethical behaviour (Browne and Peek 2014; see also Kelman 2015).

A final perspective of relevance here are the recent proposals from within geology to put intoplace a specifically geo-ethical codex akin to the Hippocratic Oath (Ellis and Haff 2009; Lucchesi andGiardino 2012). Much like Hulme’s writing referred to above, this geo-ethical movement (seeHenriksen 2005; Wyss and Peppoloni 2015) can be seen in light of current concerns for climatechange and climate catastrophe, but also in relation to recent catastrophic environmental eventssuch as the 2009 L’Aquila earthquake in central Italy and its dire consequences for lives andlivelihoods. While now freed from these allegations, the scientists advising on quake predictionand likely consequences were originally charged with manslaughter (Cocco et al. 2015). The processfrom the original charge to the eventual release of the scientists in question has been widelycriticized by the scientific community (e.g. Aarden 2012; Fast 2012; Boschi 2013; Cocco et al.2015), but has also led to some soul-searching in relation to the ethical commitment, responsibilitiesand legal status of advising scientists (Alemanno and Lauta 2014; Donovan and Oppenheimer2014b). The current version of the proposed ‘Geoethical Promise’ (Matteucci et al. 2014, 191)reads as follows:

● I promise I will practice geosciences being fully aware of the involved social implications, andI will do my best for the protection of geosphere for the benefit of mankind [sic].

● I know my responsibilities towards society, future generations and the Earth for a sustainabledevelopment.

● In my job I will put the interest of society at large in the first place.● I will never misuse my geological knowledge, not even under constraint.● I will always be ready to provide my professional assistance when needed; I will always make

my expertise available to decision makers.● I will continue to improve my geological knowledge lifelong and I will always maintain my

intellectual honesty at work, being aware of the limits of my capabilities and possibilities.● I will act to foster progress in geosciences, the dissemination of geological knowledge and

the spreading of the geoethical approach to the management of land and geologicalresources.

● I will honor my promise that in my work as a geoscientist or certified geologist will be fullyrespectful of Earth processes.

While the ethical foundations for such undertakings go back to classical philosophy, thepromise as presented is quite strongly consequentialist and presents the most overtly prescriptive

statement on professional ethical behaviour that might also be relevant to archaeologists. Writingnot just concerns of stewardship into this promise, but awarding future societal concerns andsustainable development pride of place has evident political implications. According to thispromise, geologists should also be environmentalists – indeed, they should almost be activists.

In institutional terms, archaeology is a hybrid discipline. In the US, for instance, archaeologistsare anthropologists and usually placed within social science faculties; in Europe, archaeologytends to be situated in the faculty of humanities; occasionally there and more frequently else-where archaeology may also find its home with the natural sciences. Environmental archaeology,at any rate, makes extensive use of geological methodologies, but is by definition concernedwith human–environment relations. Environmental archaeology in general, and the subfieldfocusing on past extreme environmental events and their human impacts in particular, thushave salient points of contact with all the research fields touched on above – and hence alsowith their ethical concerns. Archaeological ethics, however, tend to be aimed at professionalpractice, the handling of human remains, interaction with indigenous communities, conflict,conservation and illegal trafficking of antiquities (Zimmerman, Vitelli, and Hollowell 2003;Aitchison 2007; Beaudry 2009), though broader approaches have also been taken (Scarre andScarre 2006). Current debates on climate change and climate catastrophe – including especiallythe conception of the Anthropocene and the notion that human history and environmentalhistory cannot meaningfully be separated (e.g. Chakrabarty 2009; Dukes 2013) – make it anurgent matter to embed ethical concerns in, at the very least, environmental archaeologicalpractice. The explicit argument that environmental issues should attract the urgent attention ofarchaeologists has been made before, initially by Kirch (2005), Mitchell (2008) and van de Noort(2011; see also van der Noort 2013). Building on these arguments, Hudson et al. (2012) also makea powerful case for why and how archaeologists should enter into contemporary debate.However, they also caution against an emphasis on catastrophist scenarios, notwithstandingthe fact that the International Panel on Climate Change (IPCC)’s own report on extreme eventsstrongly suggests that natural disasters will become more frequent and more severe in thefuture (Field et al. 2012). It has long been accepted that ‘natural’ disasters are actually cultural innature, the product of one or several natural hazards impacting vulnerable communities, puttingstrong emphasis on also understanding the historical and social constellations of the commu-nities at risk (O’Keefe et al. 1976). When it comes to volcanic eruptions – the hazard of focus inthis article – recurrence intervals are often long, giving a particular relevance to ‘palaeo-societal’records that provide insights over the long term (Riede 2015b).

Case study 1: the AD 536 event

The suggestion has been made that one or a combination of several geological or climate events inthe sixth century AD are causally related to widespread distress and cultural changes (Wohletz 2000;Gräslund 2008). Several written sources from China to the Mediterranean record unusual weatherphenomena and a persistent ‘dust veil’ that lessened the sun’s warmth and hence depressedagricultural productivity (Gunn 2000; Arjava 2006). One or several causal culprits – volcanic eruptionsin East Asia or Central or North America, meteorite or comet impacts – have been pointed to; a veryrecent study of climatic fluctuations around this time shows that most likely several volcaniceruptions and their atmospheric input together caused a prolonged period, from AD 536 to AD550, of sustained northern hemisphere cooling (Baillie 2010; Büntgen et al. 2016; Sigl et al. 2015;Toohey et al. 2016). One of the probable contributing candidate volcanoes is Volcán Ilopango in

present-day El Salvador (Mehringer et al. 2005; Larsen et al. 2008; Dull et al. 2010). Payson Sheets hasshown in an extensive series of studies how this eruption had likely affected Maya communities inthe proximal (<50 km) and medial (<500 km) area (Sheets 1979, 1987, 2001, 2004, 2008; Dull,Southon, and Sheets 2001). Against this background, he has also been able to make concretesuggestions relating to local response mechanisms and mitigation policy (Sheets 2012).

But the reach of this event, most likely in concert with at least one or several other eruptions,went far beyond Central America. In Sweden, the societal crisis of the mid-sixth century hasbeen investigated most intensely. In the Mälaren Valley area around Stockholm, these changesare reflected in a change in settlement patterns across the region, with a cessation of manyotherwise stable villages and their attendant burial grounds and a relocation of settlements tohigher ground (Löwenborg 2012); changing ritual practices can also be observed, moving fromthe outdoors to house interiors (Arrhenius 2013). This picture is replicated across all of centralSweden, and extends to many areas of Scandinavia, coupled with a detectible woodlandregression into a very large proportion of what had previously been arable land (Gräslundand Price 2012; Price and Gräslund 2015; see these publications for a wider archaeologicaldiscussion of the AD 536 event). It has been suggested that not only did agricultural productionbecome depressed due to generally adverse conditions, but that the lower temperatures andincreased precipitation led to a spread of endemic ergot, a crop disease that can, in turn, causetraumatic physical and mental conditions in humans (Bondeson and Bondesson 2014). Althoughless thoroughly investigated, the Baltic area appears to also have been affected negatively bythe poor conditions (Tvauri 2014). Potentially, a very significant population collapse may haveoccurred in the Nordic area in the course of this bad year succession: estimates have beenmade of up to 50% fatalities, on the basis of settlement abandonment and the evident extremedecline in the cultivation of arable food (Price and Gräslund 2015). Although an explicit link tothe geological or climate events of the sixth century AD has never been suggested, the manyregulations on agriculture attested in English, Irish, Frankish and German legal sources of theseventh and eighth centuries AD may be the result of – even an attempt to mitigate orcapitalize on – difficulties originally experienced in the preceding century; hints of suchdifficulties may even be found in Scandinavian regulations (Hoff 1997).

In southern Scandinavia, large-scale demographic and economic changes appear to have beeninstigated by a combination of unfavourable climatic conditions and environmental refugees fromfurther to the north (Høilund Nielsen 2000, 2005, 2006). Furthermore, a very large number of goldobjects – in particular pendants (so-called bracteates) possibly related to sun worship – appear tohave been deposited in a fervour to appease the higher powers and to let conditions return tonormal (Axboe 1999, 2001).

It has been suggested that the old religious – and by implication political – order linked to sunworship and the agricultural cycle was challenged and eventually fell out of favour. It waspotentially replaced by a more apocalyptic faith in which the millennial narrative of the end ofthe world rose to prominence, the core of what has come to be seen as a distinctively ‘Norse’mythology (Andrén 2014).

The above sketch of the AD 536 event(s) and their aftermath paints a gloomy picture ofpalpable anxiety and societal collapse. It is worth pointing out, however, that far from all scholarsagree on the causal role – or any role – of this particular episode of environmental change. Somesee it as essentially an explanatory fad, pitching a catastrophist narrative to readers eager fordrama and destruction (Näsman 1988; Wickham 2005).

Case study 2: the Laacher See eruption (12,920 BP)

Continental Europe north of the Alps is not known as a volcanically active region. Yet around12,920 BP, the Laacher See volcano erupted cataclysmically (Schmincke, Park, and Harms 1999).This eruption is part of the Rhenish Shield volcanic zone and is fed by a permanent magmareservoir (mantle plume) deep in the Earth’s crust (Zhu et al. 2012). This eruption has been studiedintensely from a volcanological perspective and many details of its eruption sequence, magnitude,intensity as well as the subsequent spread of its attendant volcanic ash (=tephra) fallout are wellknown (Baales et al. 2002; Riede et al. 2011). The eruption further affected the nearby River Rhineby damming it. This led to the rapid formation of a temporary lake and upstream flooding in theRhine itself as well as its tributaries in the region. During or shortly after the eruption, the dambroke, sending debris-laden flood waves down the Lower Rhine channel (Park and Schmincke1997, 2009). Fluvially transported tephra is found all along the reaches of the Lower Rhine as far asthe English Channel (e.g. Autin 2008; Janssens et al. 2012).

While the impact of this eruption on climate was likely minor and not long-lived (Graf andTimmreck 2001), its signature in terrestrial and lacustrine environmental archives is subtle but clear(e.g. Magny et al. 2006; De Klerk et al. 2008; van Raden et al. 2013). Despite these seemingly minorenvironmental impacts, a strong case can be made for specifically human impact, especiallybeyond the proximal zone (>50 km). Here, heavy ash fall during the summer months wouldhave made it difficult for prey animals to forage, and would have hindered humans in the sameway. Furthermore, even slight tephra coatings on ingested food can lead to severe dental abrasion(Riede and Wheeler 2009) and, owing to the fallout’s heavy fluoride (F) load (Harms and Schmincke2000), F-induced poisoning (cf. Cronin et al. 2000). These combined effects may have led to thetemporary abandonment of some parts of Central Europe – where numerous sites show astratigraphic sequence of occupation–ash fall–abandonment (Riede 2012, 2016) – and the migra-tion of Late Glacial forager groups to southern Scandinavia and their subsequent isolation there(Riede 2014b). This isolation has been suggested to have contributed in turn to the emergence ofthe regional archaeological phenomenon known as the Bromme culture, which is marked by a forthis period uncharacteristically simple flint technology and the absence of arch-backed elementsindicative of the key weapon system of the time, the bow and arrow (Riede 2008). While noarchaeological remains survive that can inform us about changes in worldview and the kind ofanxiety provoked by the events in the sixth century AD sketched out above, a consideration ofhow the unfolding of this cataclysmic event would have been experienced by contemporaries inregions far removed from the eruptive centre can also in this case provide hints as to howunsettling the years – perhaps even decades – around 12,920 BP may have been (Riede 2015a).

Like the AD 536 event, this scenario has not gone uncontested. Some have suggested that theBromme culture, instead of being the result of isolation, reflects the seamless adaptation of foragergroups to local conditions (Sørensen 2010), or that the dating resolution is insufficient to resolvewhich environmental or other factors drove the emergence of the Bromme culture (Weber, Grimm,and Baales 2011). Subsequent studies have attempted to address these issues (Riede andEdinborough 2012), but the debate is ongoing (Riede 2013; Buck Pedersen 2014; Riede 2014a, 2016).

Discussion

Volcanic eruptions obviously posit major threats to lives and livelihoods in the present (Self 2006;Donovan and Oppenheimer 2014a). Population growth and increasing urbanization further

aggravate volcanism-related vulnerability (Chester et al. 2001; Small and Naumann 2001). Volcaniceruptions are commonly rated on either the semi-quantitative Volcanic Explosivity Index (VEI;Newhall and Self 1982) or on a more strictly quantitative Magnitude (M) scale (Mason, Pyle, andOppenheimer 2004). The two eruptions that make up this article’s case studies are large, bothassociated with VEI and M scores of c. 6 (cf. Crosweller et al. 2012). The threat posed by futurevolcanic eruptions must, however, also take into account the recurrence rate and the potential ofhuman impact in the near and far fields. The Laacher See volcano, for example, is located in thedensely settled heart of Europe, close to a large number of key infrastructure installations and inthe immediate vicinity of major air traffic hubs (e.g. Frankfurt, Amsterdam) and at least oneimportant water route, the River Rhine (Uehlinger, Wantzen, and Leuven 2009). Assuming analo-gous ash fallout patterns, 13 contemporaneous countries would be directly affected, from Italy inthe south to Russia in the north. For the AD 536 event, similar cooling patterns are expected tocause major pressure on agricultural supply chains (Engvild 2003) with likely follow-on implicationsfor migration and political stability. Indeed, migratory responses (or absolute population decline)stand out as shared features of the two case studies presented in this article, and migration is alsothe major outcome of more recent eruptions (Witham 2005). Migration brings crises from region toregion independently of their point of origin; environmental refugees present a major politicalchallenge in the present (Oliver-Smith 2009; Black et al. 2011).

Both the eruption of Volcán Ilopango and the Laacher See rate quite highly (3–4) on Pyle’s (2000)scale of destructive potential, on a par with volcanoes such as Pinatubo and Laki that are widelyconsidered major threats if they erupt again (cf. Schmidt et al. 2011). Similarly, Scandone, Bartolini,and Martí (2015) have recently proposed a risk-based ranking of volcanoes that projects risk into thefuture based on basic parameters of past eruption characteristics and the contemporary setting of agiven volcano. Their Volcanic Risk Coefficient (VRC) is based on a straightforward rank-basedalgorithm

KT þ VEIþ log Npop� �

where Kt is time since last eruption, VEI represents the likely worst-case eruption scenario, and thelogarithm of the affected population number is meant to capture how many people would beimmediately affected by a given eruption. Following Scandone and colleagues’ guidelines, theLaacher See (Kt = −5; VEI = 6; log(Npop) = 7) as well as Volcán Ilopango (Kt = −3; VEI = 6; log(Npop) = 5) would be ranked with a VRC of 8, i.e. they represent – despite or perhaps preciselybecause of their long quiescence – considerable environmental threats.

Donovan and Oppenheimer (2014a) have tersely outlined how eruptions of this magnitudewould challenge existing economic and geo-political orders. They have suggested elsewhere thatscientists – especially social scientists – have an important role to play in meeting and commu-nicating these future challenges (Donovan and Oppenheimer 2014a, in press). Similar argumentshave been made by sociologists: unlikely but possible disaster events should not be ignored butused as productive planning tools, and scientists should provide the necessary information,inherently uncertain though it might be (Oreskes 2015), for constructing such scenarios (Clarke2008; Clarke and Molotch 2010). The temporal depth of historical and sociological studies ofdisaster is limited, however, and it is here that archaeology stands to make a major contribution.

The narrative quality of archaeological accounts concerning past vulnerability and resilience canhere provide important input not only for the historically informed evidence-based formulation andparameterization of future impact scenarios, but also for subsequent outreach that can affect people’sbehaviour. Better, richer narration about local and regional impacts is said to be missing from official

accounts of climate change and catastrophe (Nielsen 2013; Carter and van Eck 2014). Geo-ethicists,too, argue that narratives are one way to present past human–environment relations to both publicand policy-makers (Bohle 2015). Yet most recent analyses show that the humanities, includingarchaeology, are making only insignificant contributions to major policy-driving reports such as theIPCC outputs (Corbera et al. 2016). One reason for this imbalance may be sought in differentialfunding regimes. Of the many disciplines involved in disaster risk reduction research, for instance, thenatural science and engineering fields receive the vast bulk of financial support (Alexander 1997;Sheets 2012). At the same time, it is scientists in these fields who are also shouldering the greatestresponsibility when it comes to prediction and mitigation measures – and their potential failure. Thus,if archaeologists were to take a more involved stance when it comes to future climate and naturalhazard risks, it is likely that the perceived insignificance of the discipline would be re-evaluated.Adopting an ethical promise that takes environmental archaeology beyond stewardship and towardsaction could be one step towards such proactive engagement.

Conclusion

Environmental archaeologists have longbeen interested in the impact of past climatic andenvironmentalchanges on human communities (Butzer 2012). Such studies often court controversy precisely becausethey resonate with contemporary concerns of societal collapse (Middleton 2012). However, the environ-ment features all too rarely in standard narratives of human prehistory and history, other than as a broadcanvas or a wilderness to be tamed from Neolithic times onwards. Yet, as Chakrabarty (2009) haspowerfully observed, the Anthropocene perspective collapses the once foundational distinctionsbetween environmental, economic and political histories. Adopting the Deep History perspective ofHarvard historian Smail (2008), these insights are as valid for recent history as for the distant past.Engaging policy-makers on this basis might offer one avenue towards an ethically engaged environ-mental archaeology, where archaeology can, at the very least, provide added outreach value to studies ofpast environments or natural hazards. In other fields of archaeological ethics – for instance, studies of civilwar or gender inequality, or work with indigenous or descendant communities – it has been fairly widelyaccepted that researchers cannot avoid ‘taking sides’. In these cases, archaeology should be applied, andthe past should be ‘usable’ (Stump 2013). The politicizing of environmental relations under the label ofthe Anthropocene (see Braje 2015) makes environmental change, extreme events and their humanimpact a strong candidate for similar (and similarly political and ethical) engagement for an‘Environmental Archaeology of the Future’ (cf. Wurst and Mrozowski 2014). The undesirable flip side ofsuch engagement can, however, be the subjugation of the uncertainties inherent in scientific work – alsopresent in the two case studies referred to in this article – to political convictions (cf. Kelman 2015).

An alternative or complementary pathway is that of education. Science museums the worldover are tackling the profound societal challenges of the climate change debate (Cameron, Hodge,and Salazar 2013; Cameron and Neilson 2015), yet museums of culture history do so but rarely(Hansen et al. 2014). There are exceptions (Robin et al. 2014; Blæsild and Beck 2016), but thesespecial exhibitions on environmental histories are hardly – if at all – archaeologically oriented anddo not reflect an integration of environmental narratives into mainstream narratives of long-termculture history. As Holtorf and Högberg (2015) have convincingly argued, heritage is by definitionfuture-oriented and practitioners are obliged to ask themselves why they are conducting theirwork and for whom. Conservation, heritage management (stewardship) as well as recording andstudying archaeology refer to the future and to future generations. If environmental archaeologythen does all these things specifically in relation to environmental futures, an ethical and political

engagement seems, at some level, unavoidable. Framed in this way, past natural hazards ingeneral, and the two cases discussed in this article, arguably present a form of environmental‘Dark Heritage’ that focuses mostly on the dire consequences of low-frequency/high-magnitudeevents. Yet, as political economic/ecological events, every disaster has its winners and losers(Scanlon 1988) and they can also be framed as opportunities for societal change (Birkmannet al. 2010; Olshansky, Hopkins, and Johnson 2012), perhaps especially so in relation to ourcontemporary risk society as suggested by the late Ulrich Beck (2015). Environmental or geo-cultural heritage could here serve as a resource for conceptualizing alternative future engage-ments, or in the words of Schlanger, Nespoulous, and Demoule (2016, 409), a ‘contemporaryfuture’ shaped in part by catastrophic events. In Japan, suggestions for putting in place heritagenetworks (Okamura et al. 2013) and even a museum dedicated to the 2011 earthquake and itsaftermath (Kikuchi and Nespoulous 2015) are steps in precisely this direction. This environmentalDark Heritage can play a role in mitigation, healing and education. However, the sad irony here isthat such initiatives follow only in the wake of major calamities in the present, rather than drawingon the already existing and no less important archive of past disasters. According to Mitchell(2008), archaeologists do have a responsibility to contribute to the debate on environmentalchange and environmental catastrophe. As a profession, we have very particular methods at ourdisposal for investigating disasters and their material and societal consequences, and these can bemade to work vis-à-vis public engagement with the ethical dimensions of environmental calami-ties (Dawdy 2009). While we shy away from drafting an ‘Environmental Archaeology Promise’along the lines of that proposed by our colleagues in geology, a discussion on the pros and consof such a document might be a vital step along the path towards structured action rather thanindividual activism.
