A Strategic Framework for Monitoring Coastal Change in Australia's Wet-dry Tropics – Concepts and Progress

A strategic framework for monitoring natural and human-induced change in the coastal plains of the Alligator Rivers Region in the wet-dry tropics of northern Australia is presented. The framework also supports refinement of methods used to monitor the vulnerability of coastal areas to change, including human-induced climate change and sea-level rise. The information derived through the framework can be used to assess scenarios, highlight the potential significance and implications of changes, and assist land managers formulate management responses. The framework incorporates several large-scale studies for monitoring atmospheric and hydrodynamic processes as well as mapping and monitoring projects specific to environmental change in the freshwater wetlands and the floodplains of the Region. Monitoring is proposed to address processes influencing the stability and rate of change of the floodplain environments. These include large-scale processes, such as inter-annual variability in weather conditions affecting the morphology of the coastal plains, shoreline and riverbank stabilisation, headward expansion of tidal creeks, and salinisation of freshwater basins. Information management is also addressed, and a Geographic Information System structure proposed for effective data collation, analysis and management. The information management system will facilitate data sharing and participation of multiple agencies and organisations interested in coastal change, especially where a landscape perspective or whole ecosystem approach is advocated.     

Multi-disciplinary research on the past human ecology of the east Arabian coast: excavations at Hamriya and Tell Abraq (Emirate of Sharjah, United Arab Emirates)

The results of two seasons of research at Hamriya and Tell Abraq (Sharjah, UAE) by an international team of researchers are presented. The research has revealed extensive evidence for occupation from c. 5000 BC to the recent past adjoining lagoon areas that face the Arabian Gulf. C¹⁴ analysis of shells has contributed to understanding the chronology of settlement and also assisted our understanding of species-specific deviation from the global reservoir effect.     

Archaeological Investigations in the Harbours of Burgaz,Turkey: 2011–2015 field seasons

Between 2011 and 2015 archaeological fieldwork was conducted in the Archaic through Late Antique harbours associated with Burgaz on the Datça Peninsula in south‐west Turkey. This work focused on survey and documentation of built features associated with the four harbours, limited stratigraphic excavation, and identification of shipwrecks and seafaring activity outside the harbours. The results offer new insights into the growth, expansion, and eventual abandonment of the port complex, its development alongside the urban settlement, and its changing maritime dynamics in light of economic shifts across the peninsula and the eastern Mediterranean.     

Refining Broad-Scale Vulnerability Assessment of Coastal Archaeological Resources,Lough Foyle,Northern Ireland

Increasing evidence indicates that ongoing and future climate change impacts, such as enhanced coastal erosion driven by intensified storms and sea-level rise, will be destructive or problematic for coastal archaeological heritage. Approaches to this problem range from broad-scale GIS-based vulnerability assessments to site-scale monitoring and survey. In all cases, the approach chosen should be based on the best-available data on the local historic environment and pattern of coastal change. Therefore, this paper will demonstrate how such data can be successively acquired and enhanced using an integrated approach that builds on and refines a previously conducted broad-scale vulnerability assessment. This approach was adopted in the study region (Northern Ireland) owing to a lack of coherent and up-to-date information on shoreline change. This approach incorporated the GIS-based Digital Shoreline Analysis System (DSAS) to quantify and analyze local shoreline change. DSAS is a software extension for ESRI ArcGIS which allows calculation of rate-of-change statistics using past shorelines identified from georeferenced historic maps and vertical aerial imagery. Additionally, a field survey was conducted to assess the condition of recorded sites, and identify unrecorded ones. Results revealed a more complex pattern of shoreline change in the study area (Magilligan Foreland, Lough Foyle) than previously anticipated, with zones of significant erosion interspersed with areas of stability or advance. Fifty-one new sites ranging from the prehistoric period to the Second World War were also identified. The new information was used to develop a priority classification based on site significance, condition and risk level which improved significantly on the uniform classification of the original broad-scale assessment.     

Osteometric Analysis of South American Sea Lions (Otaria flavescens) Pups From Patagonia. An Assessment of Their Use as Indicators for Seasonality in Archaeological Sites

Zooarchaeological analyses of pinniped remains have been scarce in South America because of lack of specific studies of species determination and estimation of age and sex. Nonetheless, the presence of small and unfused bones (assigned as pup remains) of Otaria flavescens (O. flavescens) in the Patagonian archaeological record has been frequently used as an indicator of summer occupation accomplished by ecological analogues. For this reason, we carried out a postcranial skeletons osteometric study of modern pups of South American sea lions (O. flavescens) with known sex and aged 0–12 months, allowing a more precise age estimation of archaeological samples. Then, we revisited the evidence for seasonality in the Cabo Virgenes 6 site at Cabo Virgenes locality, one of the archaeological localities in Patagonia where the seasonality has been determined only on the basis of the presence of unfused pup bones. Our metric data study on a modern sample shows that the regression analyses generated a complementary and dependable age estimation model for unfused appendicular bones of O. flavescens between 0 and 12 months old that can be applied to samples recovered from archaeological sites. These osteometric studies of postcranial elements allow us to adjust the age estimation of the animal's death and re‐examine seasonality of the Cabo Virgenes 6 site (Santa Cruz, Argentina).

Scotland's coast: Understanding past and present processes for sustainable management

The coastline of Scotland is extremely long and varied. It comprises most of the major types of coastal environment and includes machair, a sand dune system that is unique to the western seaboard of the British Isles. Such variety has its roots in the geology and sea level inheritance of Scotland and demonstrates that long‐term processes still exert a profound influence on coastal form and functioning. Understanding how these processes affect the coast and influence such diversity is essential to efficient coastal management, although it is also imperative that the vision, strategy and political will to deliver such management are also in place.     

Associations between coastal proximity and children’s mental health in Australia

Limited research has explored associations between blue spaces and mental health, specifically in children. This study assessed links between coastal proximity and depression and anxiety among children in Australia and tested whether duration of residency at current address moderated associations. It also explored associations between within-individual changes in coastal proximity and changes in depression and anxiety. Data were from 2400 children aged 11–12 years in Wave 5 (2012) and aged 14–15 years in Wave 6 (2014) of the national Longitudinal Study of Australian Children. Outcomes were children’s self-reported symptoms of depression and anxiety. Exposure was coastal proximity (<2, 2–<5, 5–<10, 10–<20, 20–<50, and ≥50 km). Linear models were fitted to examine cross-sectional associations and fixed effects models for within-individual associations. After adjustment for potential confounders, findings suggested that those living close to the coast (<2 km) had lower levels of depression than those living the furthest from the coast (≥50 km) during childhood (Wave 5) but not adolescence (Wave 6). No associations were observed with anxiety. There was weak evidence to suggest residency duration moderated associations. No associations were observed for within-individual changes. Further research is needed to understand whether and what characteristics of coastal environments may benefit children’s mental health.     

Prehistoric hunters and gatherers of Brazil

Although carbon-14 dates prior to 13,000 B.P. have been obtained from several sites east and south of Amazonia, their reliability is uncertain. By about 11,000 B.P., however, two lithic traditions were widespread. The Uruguai tradition, characterized by bifacial stemmed projectile points, was associated with open vegetation in the south; the Itaparica tradition, emphasizing well-formed unifacial artifacts, had dispersed over the eastern tropical parklands. An enormous amount and variety of rock paintings and/or engravings are associated with the latter. Around 7000 B.P., two new traditions emerged to exploit new habitats. The Humaitá tradition, characterized by large bifacial tools and an absence of stone projectile points, expanded over the broad-leaved forests in the south, leaving the open landscapes dominated by the projectile point-using Umbu tradition. The sambaqui (shell midden) tradition, also emphasizing large bifaces, developed along rugged portions of the southern coast. By 4000 B.P., groups along the coast of Rio de Janeiro and Espírito Santo were using domesticated or semidomesticated plants, perhaps sweet manioc. Maize was being grown in Minas Gerais by about 3500 B.P. Carbon-14 dates from numerous sites indicate, however, that the hunter-gatherer way of life persisted in many places long after the advent of pottery-making horticulturalists. The existence of large temporal and spatial gaps even in regions with considerable investigation makes it difficult to reconstruct the process of evolution reflected in these archaeological complexes. Correlations between cultural traditions and environmental fluctuations indicate, however, that adaptation to changing conditions was a significant challenge faced by prehistoric Brazilian populations.     

Down by the sea: visual arts,artists and coastal regeneration

This paper takes a critical approach to the arts-led regeneration of Margate, south east England. It argues that regeneration policy has effectively utilised local characteristics to recreate Margate as an artful space, and has stimulated a local milieu of artistic and cultural activity. However, though the work of local artists is vital in producing Margate as a creative place, local artists are marginalised by policy interventions focussed on attracting new consumers and investors. Thus, this paper argues that a misplaced policy emphasis is failing to support the labour and social relations on which the interpretation of places as ‘creative’ is built, and arguably undermines the sustainability of an arts-based regeneration. This has implications for culture-led policy, calling for greater attention to be paid to the specific locations in which it is deployed, and to the networks of producers whose labour is critical to its success.     

Hunters of forests and waters: Late Iron Age and Medieval subsistence and social processes in coastal northern Sweden

During the course of the 14th century the Swedish Crown and the Catholic Church made robust attempts to include the areas beside the Bothnian bay within their central fiscal and clerical organization. Salmon fishing in the productive river rapids became major targets for external commercial interests. Written records inform us about the situation from the perspective of the exploiters. However, there is a story running in parallel – that of the local population already occupying the lands and the fishing grounds. The study aims to analyse the significance of hunting and fishing to the overall subsistence of coastal communities in northern Sweden during the period AD 500–1600. The social context is of particular interest, specifically in relation to the successive conformation by the local communities to the Swedish fiscal system. The study draws on archaeological records and on historical records from the 14th to the 17th century, in addition to ethnographic accounts for hunting and fishing. We conclude that the legal cultures embraced by the indigenous population and that of the Swedish central powers were in essence incompatible. The acquisition of land and fishing rights was never settled between two equal parties, but one-sidedly enforced by the party holding the pen.
