This article complements the archaeological account of the so‐called ‘Edesö Wreck’ with archival research that has led to its identification. In 1659 the Swedish King Karl X Gustav ordered a number of vessels for transport of horses and soldiers while at war with Denmark. The king died just a few months later, the war with Denmark was aborted, and the unfinished vessels were rebuilt to serve other purposes. One of these was Bodekull, built under English master shipwright Thomas Day between 1659 and 1661. In October 1678 Bodekull sank in the Stockholm archipelago. Alterations made during construction mentioned in written sources have been noted on the wreck and strengthen the argument for the identification.  相似文献

A poor understanding of the physical environment often hinders management of marine artefacts. A study was conducted of an early-18th-century shipwreck to test whether the wreckage could have settled through ∼3.5 m of substrate. Results indicate that the wreck could have settled via episodic scour processes driven by storms and tidal inlet migration. A numerical model, modified to include characteristics of the underlying geology, predicts continued scour under moderate waves. Scour processes appear to have been interrupted by an erosion-resistant underlying layer, so that the wreck now remains exposed, subject to degradation. A generalized approach to predict burial or exposure of other shallow-water artefacts is developed.

Community‐based conservation is experiencing a crisis of identity and purpose as a result of a disappointing track record and unresolved deficiencies. The latter include over‐simplified assumptions and misconceptions of “community,” the imposition of externally designed and driven projects at the community level, a focus on conservation outcomes at the expense of community empowerment and social justice, and limited attention to participatory processes. New approaches are urgently needed to address these weaknesses and to counter a rising trend towards environmental protectionism and a preference for conservation approaches at an eco‐regional scale that threaten the interests of local and Indigenous communities. We propose that three core principles of community‐based participatory research (CBPR)—(1) community‐defined research agenda; (2) collaborative research process; and (3) meaningful research outcomes—hold much promise. Drawing on the experience of a research partnership involving the James Bay Cree community of Wemindji, northern Quebec, and academic researchers from four Canadian universities, we document the process of applying these principles to a community‐based conservation project that uses protected areas as a political strategy to redefine relations with governments in terms of a shared responsibility to care for land and sea. We suggest that basic assumptions of CBPR, including collaborative, equitable partnerships in all phases of the research, promotion of co‐learning and capacity building among all partners, emphasis on local relevance, and commitment to long‐term engagement, can provide the basis for a revamped phase of community‐based conservation that supports environmental protection while strengthening local institutions, building capacity, and contributing to cultural survival.  相似文献

One important extension of the IAD framework has been to the study of local public economies. These are multi‐organizational, multi‐level arrangements defined as the set of governmental jurisdictions, public and nonprofit agencies, and private firms that interact in various patterns to provide and produce public goods and services within a specific locality or region. Commonly, the localities or regions studied from this perspective have been U.S. metropolitan areas, often defined as a central city and its surrounding or adjoining county. Localities can be delineated, however, on various terms, and in the IAD framework, it is the geo‐physical nature of a locality that, in substantial part, drives the analysis. One of the strengths of the approach is its capacity to explain local variations in public organization as a function of the geo‐physical diversity of localities, while at the same time developing empirical generalizations and normative principles that apply across diverse regions. What, for example, might the organization and governance of a complex metropolitan area have in common with the organization and governance of a complex protected area, such as the greater Yellowstone eco‐region or the Adirondack Park? Construing both sorts of regions as local public economies can enhance our overall understanding of public organization at the same time that it permits a more nuanced understanding of diverse localities. Such work contributes to the ongoing IAD project of “understanding institutional diversity.”  相似文献

L’adaptation aux changements climatiques dans les réseaux d’aires protégées du Canada : état des lieux La Commission mondiale des aires protégées a récemment laissé entendre que les actions en faveur de la conservation sont vouées à l’échec, à moins que ces dernières tiennent compte des changements climatiques. Pour ce faire, les organismes chargés des aires protégées doivent dès maintenant s’assurer de l’intégration des changements climatiques dans les politiques, les cadres de planification et les modes de gestion. Le présent article rend compte des résultats d’une enquête réalisée conjointement par l’Université de Waterloo et le Conseil canadien des aires écologiques. Celle‐ci vise à dresser un état des lieux sur l’adaptation aux changements climatiques dans tout le réseau d’aires protégées du Canada qui relève du palier fédéral, provincial ou territorial. Il se dégage de l’analyse plusieurs constats importants. Tout d’abord, sur l’ensemble des organismes chargés des aires protégées que nous avons interrogés, les trois quarts ont déclaré que les changements climatiques ont déjà des effets visibles sur leur réseau d’aires protégées. Ensuite, 94 pour cent des participants à l’enquête estiment qu’au cours des vingt‐cinq prochaines années, l’enjeu des changements climatiques sera au c?ur de la politique et de la planification des aires protégées. Finalement, malgré la perception voulant que les changements climatiques exercent une pression croissante, la portée des mesures politiques, de planification, de gestion ou de recherche mises de l’avant par la plupart des organismes jusqu’à maintenant demeure limitée. Si 91 pour cent des organismes indiquent ne pas disposer des capacités nécessaires en ce moment pour réagir de façon optimale aux changements climatiques, l’enquête a permis de mettre en évidence un écart significatif entre la perception de la gravité des changements climatiques et la capacité des organismes chargés des aires protégées de s’adapter. La faiblesse du financement, une capacité d’action limitée, et un manque de compréhension des changements climatiques et de leurs répercussions réelles ou potentielles comptent parmi les difficultés auxquelles sont confrontés les organismes canadiens chargés des aires protégées. Il est impératif de les surmonter afin que ces organismes puissent exercer leurs mandats et être en mesure d’assumer leurs responsabilités concernant la protection et la biodiversité des aires, par exemple, la protection de l’intégrité du patrimoine naturel au Canada dans un contexte de changements climatiques accélérés.  相似文献

Analysis of the pre‐disturbance values of the in situ corrosion parameters on historic iron shipwrecks and artefacts has established that the arithmetic product of the pH and corrosion potential is dependent on the burial environment and provides a unique insight into the objects' state of decay. The value of the product changes during in situ conservation treatment with sacrificial anodes, and reaches a minimum at which point the treatment is completed. Treatment times vary with water‐depth, being faster on shallower sites and shorter for more extensively corroded artefacts. The model was developed using data from the Duart Point wreck (1653), the Monitor‐styled warship HMVS Cerberus (1926) and a series of wrecks in Australia and the USA.  相似文献

Large quantities of sardine (Sardina pilchardus) bones from amphorae in a wreck at Randello, Sicily, were examined. Methods of estimation of size of the fish represented using the lower jaw bone (dentary) and the gill cover (operculum) by comparison with those of modern fish are given. Both methods give comparable results; from dentaries 108–171 mm and from opercular bones 116–176 mm total length.  相似文献

Unprecedented bushfire activity is increasing around the world. A catastrophic bushfire event in the Australian summer of 2019–2020 burned over 18 million hectares. The Australian bushfires were just one set of events among many across the globe. Cumulatively, the losses are extraordinary: from losing over a quarter of the Pantanal wetland in South America to California’s Sierra Nevada and losses in the Amazon Forest. Bushfire destruction means a concomitant loss of biological diversity. Increased fire activity and frequency can adversely affect adaptive capacities of flora and fauna. Accordingly, across the globe, fire management practices and mitigation strategies are under increased scrutiny. In this article, we consider the extent to which one fire suppression strategy, prescribed burning, takes account of non-human considerations. Our examination of policy settings provides policymakers with a way to account for non-human interests. Our focus is Australia, specifically relating to one national park within New South Wales. Across the world, fire containment strategies must be reassessed to decipher how well non-human considerations are placed to withstand changing fire regimes. With likely increases in bush and wildfire activity across the globe, associated with Anthropocentric climate change, there is an urgent need to account for non-human interests in prescribed burning policies and regulations.  相似文献

The condition of a wooden shipwreck varies considerably according to the nature of the site environment. Each marine site exhibits a unique biodeteriogenic potential influenced by prevailing hydrographic factors. The potential rate of degradation of organic archaeological material can be determined by monitoring the diversity and activity of marine organisms and is important in determining if in situ protection is required. To illustrate the deteriogenic potential of marine archaeological sites a cold water site (Langstone Harbour, UK) was compared with a warm water site (Zakynthos, Greece). The warm water site supported a greater diversity and activity of wood-boring crustaceans and molluscs than the cold water site. However, although the mycodiversity at the two sites was different the deteriogenic potential was similar. These results indicated that warm water sites are more hazardous and in situ protection is required during and after excavation.  相似文献
