Mud Brick Metaphysics and the Preservation of Earthen Ruins

In the conservation of built heritage, earthen ruins rank as one of, if not the most, intractable of problems to be confronted. Lacking the very architectural devices originally in place to combat and control weathering, earthen ruins face rapid deterioration without constant remedial and preventive conservation. Often it is the enormous mass of many ancient earthen ruins that explain their persistence; however, even these will collapse over time from differential erosion, or eventually stabilize as formless lumps. The impossible demands of simultaneously preserving architectural form and fabric (materiality) challenge the archaeologist and conservation professional who attempt to manage both for temporary and permanent display.     

UNESCO World Heritage Site of Lenggong Valley,Malaysia: A Review of its Contemporary Heritage Management

This article reviews contemporary heritage management through a systematically coded content analysis at one of Malaysia’s UNESCO World Heritage Sites: the Archaeological Heritage of the Lenggong Valley (AHLV). It evaluates the competency of the preliminary Conservation Management Plan (CMP) of AHLV by looking at the accuracy of five distinctive dimensions of the CMP in conveying the information about the sites and management objectives: the legislation related to the heritage conservation and management; the action and implementation of the management strategies; the level of stakeholder’s participation; and, finally, how the CMP integrates local values and ideas into management planning. The results show that contemporary heritage management planning at Lenggong Valley tends to prioritize the conservation of the archaeological values of the sites over other values (i.e. social, historical, and aesthetic values), and that planning has largely been in the hands of governmental agencies with limited involvement from local communities in the decision-making process.     

The politics of wetlandscape: fishery heritage and natural conservation in Hong Kong

The north‐western part of Hong Kong is a marsh with traditional freshwater fish farming; however, this brackish area has been agriculturally diversified to include cultivation of red rice, reeds, shrimp and fish, and has only largely concentrated on freshwater fish farming starting from the 1960s. By looking into the geographical and social changes that have taken place in the brackish area, I will explain how the coastal landscape was changed in the 1910s through the introduction of large‐scale rice production in Tin Shui Wai which has turned into a high‐density residential new town, and the wetland conservation of Mai Po marshes. This article aims at understanding the meanings of intangible as well as agricultural/fishery heritage and the local politics among indigenous communities, conservation groups, the government and developers in post‐handover Hong Kong society. Inland freshwater pond cultivation was actually a major industry in the 1970s since it supplied most of the freshwater fish for the local market. Nowadays, the industry is shrinking because of lack of manpower and high operation costs compared to the mainland. With various kinds of social, economic and physical pressures, the local communities which are located at the buffer areas of the wetland in Mai Po are actually facing the tremendous dangers of losing those fishponds; most importantly, the fishponds have been serving not only as mitigation zone and source of a traditional local food but also as a major food supplier for migratory birds, adding to the conservation value of the Mai Po marshes and Inner Deep Bay in Hong Kong at large.     

Understanding and using built heritage: Singapore’s national monuments and conservation areas

Issues of heritage administration in the city state of Singapore are examined in the paper with specific reference to decisions about the designation of national monuments and conservation areas. The analysis reveals growing official interest in built heritage conservation for a combination of economic, socio‐cultural and political motives. However, commitment is constrained by the importance attached to economic development objectives and there is an emphasis on maximising the commercial potential of old buildings through adaptive reuse. Questions are also raised about the meanings of national identity and nationhood and the challenges of selecting and preserving structures which embody these concepts in relatively young and rapidly modernising countries.     

Heritage studies and the privileging of theory

Heritage studies is yet to have a debate about its theorisation at the global level. Many of the core ideas that shape the field are rooted in the contexts of Europe and the USA and geographically rolled out in normative ways. This paper argues it is important we embark on pluralising how heritage is studied and theoretically framed, in ways that better address the heterogeneous nature of heritage, for both the West and the non-West. The themes of modernity, cities and international cultural policy provide evidence of why we need to better position the academic study of heritage in relation to the rapid geo-political and geo-cultural shifts now taking place.     

The Australian Historic Shipwreck Preservation Project: In situ Preservation and Long-Term Monitoring of the Clarence (1850) and James Matthews (1841) Shipwreck Sites

Increasingly, archaeologists are opting for on-site examination, reinterment, and in situ preservation of underwater cultural heritage sites as the first option in the management of sites at risk, as opposed to the more traditional excavation, recovery, conservation, and display/storage methods. This decision will inevitably be based on significance assessment, degree of perceived risk, and resourcing issues. However, long-term monitoring must become an integral part of these management programmes in order to quantitatively evaluate the effectiveness of the in situ preservation techniques employed. In 2012 the Australian Historic Shipwreck Preservation Project (AHSPP) was awarded a large Australian Research Council (ARC) Linkage Grant, enabling ten partner organizations and three Australian universities to collaborate in one of the largest multi-organizational maritime archaeology projects to be undertaken in Australia to date. One of the major aims of the project is to develop a protocol for the excavation, detailed recording and reburial of significant shipwrecks under threat, fostering a strategic national approach for the management of underwater cultural heritage (UCH) sites at risk. Two historically significant shipwreck sites that are considered under threat were chosen for this longitudinal comparative study — the Clarence (1850) located in Port Phillip Bay, Victoria; and the James Matthews (1841) which lies in Cockburn Sound, Western Australia. Both sites have been preserved in situ using two very different but innovative remediation strategies. More importantly, long-term monitoring programmes have been implemented on both sites, which will characterize changes in the reburial environment and the effect on the reinterred materials. In this way, the efficacy of both in situ preservation techniques will be systematically tested, providing a comparative analysis of practical protocols for the long-term protection and management of underwater cultural heritage.     

Development of a Methodological Framework for Handling Urban Archaeological Resources: Tarsus Historic City Centre,Turkey

In Turkey, most of the historic city centres have been continuously occupied since early ages, and ongoing research or ad hoc findings indicate urban archaeological resources beneath modern cities. According to the results of such research, archaeological and conservation sites are determined in terms of current legal frameworks. However, urban archaeological resources have not been included in the planning process because of inadequacy in spatial documentation, so archaeological deposits have been seen as problem areas in urban development. Thus, urban archaeological resources — not only subsoil resources, even monumental sites — could not be integrated into urban daily life, so most citizens are not aware of archaeological layers beneath their feet. The research project in Tarsus historic city centre, which is supported by the Scientific and Technological Research Council of Turkey (TUBITAK), primarily aims to develop a method to include urban archaeology — especially subsoil archaeological resources — into the urban conservation planning process of multilayered historic city centres in Turkey. In this way, planners would be informed, aware, and equipped about the urban archaeological potential at the earliest stages of the planning process. Consequently, urban archaeology, as an inter-/ multi-disciplinary field of research, is going to evolve as a crucial planning analysis in urban conservation including not only archaeological research, but also in evaluating settlement history and issues in urban development.     

Restoration Interventions at the Roman Nymphaeum in Amman: Identification and Evaluation

Abstract

Over the last few decades, conservation work has been conducted by the Department of Antiquities of Jordan (DoA) on the Roman Nymphaeum in Amman. This intervention has taken the form of direct and indirect actions. In this article it will be shown that the conservation works concentrated on reinforcing the structure and reconstructing some architectural features of the building, with little consideration of the techniques and materials used. Intervention actions were mostly poor in terms of their scientific approach, and neither proper planning nor a well-defined methodology existed. This study provides a holistic approach for the evaluation of the state of the conservation of the monument in terms of quality and quantity. Thus, the results could be a valuable source for establishing comprehensive risk mitigation for future restoration work and site management. In addition, establishing practical restoration guidelines could help in developing socio-economic benefits for the community through tourism.     

Management of Historic Shipwrecks Through a Combination of Significance and Conservation Assessments

Abstract

Corrosion modelling of decay rates of the iron wrecks in Port Phillip Bay, Victoria, has enabled an estimation of the speed at which the historic resource of iron shipwrecks is disappearing. Use of the significance ranking of the iron wrecks, based on the Australian National Standards for significance assessment, provides a useful guide to decision-making, but decisions based solely on these criteria can lead to less than optimal results. From the corrosion rates and the amount of residual metal thickness in structural elements it is possible to determine a conservation ranking that is based on the need for intervention and the chances of being successful in stabilizing the wrecks. The arithmetic product of the significance and conservation rankings defines the treatment score or ranking which forms the basis for rational decision making about deployment of resources.     

Similarity of the flora of the Erie Islands: implications for conservation biology

Using a compiled list of the vascular flora for 21 islands in the western basin of Lake Erie, Preston's resemblance measure and Connor and Simberlof's Null Hypothesis I were applied to native and alien species subsets in order to examine how these findings fit within the equilibrium theory. Based on Preston's measure, it was found that the similarity of species between island pairs was more likely to fit with MacArthur and Wilson's equilibrium theory when native species were considered than when alien species were considered. Native species have restricted distributions - especially those found on the smaller islands - and appear to be less randomly distributed about the islands. This study also found that a large component of the alien flora is widespread in its distribution, and appears to be randomly distributed among most of the islands.
