The ethnoarchaeology of firewood management in the Fang villages of Equatorial Guinea, central Africa: Implications for the interpretation of wood fuel remains from archaeological sites

In archaeological literature, the study of trees and wood remains is a topic of relatively marginal interest, especially compared to texts on crops and human–animal relations. However, charcoal is the most frequent botanical remain found in archaeological sites. Charcoal analysis can therefore play a major role in the development of studies in both landscape and palaeoethnobotanical reconstruction. The majority of the archaeological charcoal assemblages reflect the exploitation of wood as an energy source (fuel). The archaeological study of firewood selection has been predominantly developed from “eco-utilitarian” or “subsistence economy” perspectives, but has not yet considered fuel collection and use as one of the most enduring categories of human–environment interactions, nor has archaeology looked into its potential as a source of empirical information on past perceptions of, and interactions with, ancient landscapes. The aim of this paper is to expand previous archaeological work on the interpretation of charcoal macro-remains through the study of firewood collection as a historically constituted, socially mediated and archaeologically observable landscape practice. In order to achieve this, we present an ethnoarchaeological case study from the Fang society of Equatorial Guinea (central Africa) aimed at gaining a better understanding of the complex interactions between cultural, ecological and economic variables in firewood collection strategies.

Managing the risk of climatic variability in late prehistoric northern Chile

The concept of risk management encompasses the diverse strategies employed in preventing and mitigating losses associated with social and environmental calamities. Building on the growing literature on risk, we use archaeological data from the Tarapacá Valley, located in northern Chile, to document the risk-reduction tactics mobilized by the valley’s inhabitants to navigate the increasingly volatile environmental and social conditions of the Late Intermediate Period (AD 1000–1450). With the onset of exceptionally unpredictable environmental conditions after AD 1100, residents of the Tarapacá Valley chose strategies such as increased trade and agricultural diversification and extensification to minimize shortages in staple resources. Threats of raiding and intra-community strife exacerbated the risks associated with subsistence shortfalls. Valley communities elected a number of strategies to curtail conflict-induced risk, including movement of settlements and field systems to defensible locations, construction of walls and other defensive features, and the introduction of plazas. Rock art data suggest that trade was increasingly embedded in ritually sanctioned events involving groups from different ecological zones. While studies of risk have focused disproportionately on environmental hazards, subsistence-related crises are often compounded by social hazards that require their own risk-mitigating strategies, further constraining options for coping with subsistence stress.     

Paper 2: Climatic Study of the Underground Archaeological Site Coudenberg

Abstract

The excavation and valorization of subterranean archaeological remains, and eventually opening a site to the public, required a proper management and conservation strategy. This strategy was based on the evaluation of the delicate balance between the requirements for public health and safety, and the protection of the archaeological remains from future degradation. Controlling the climate can be essential for a preventive conservation strategy, which can be defined as an indirect action to increase the life expectancy of the archaeological remains, and by doing so keeping them in a preferred state of conservation to mitigate damage and/or deterioration.

Potential risks and possible interventions are outlined to avoid climatic conditions which are in conflict with the requirements for the visitors’ comfort while preventing damage phenomena to the materials.     

The Results of Cultural Management of the Croatian Archaeological Heritage with Special Consideration for Cost Effectiveness: The Case of Roman Iovia (Ludbreg)

Abstract

During the four seasons of excavations of the Roman town of Iovia-Botivo (present-day Ludbreg, Croatia), a smaller bath and sizeable (presumably public) building were discovered. An optimal plan for presentation was made with all due consideration for the site’s speci?c situation. The plan encompassed scholarly and professional requirements concerning conservation in situ combined with the needs of successful cultural management, thus resulting in alignment between the latter two factors as well as cost effectiveness. By applying the aforementioned principles (which served more as guidelines rather than rigid edicts) and facilitating successful, interdisciplinary cooperation between the national government, the municipal authorities, and researchers, it was possible to provide a sound, legally secure future for this site.     

Latitudinal variation in a photoperiod response gene in European barley: insight into the dynamics of agricultural spread from ‘historic’ specimens

Between ca. 6000 BC and ca. 500 BC, barley cultivation spread across the continent of Europe from the extreme south to the extreme north. Carbon-dating would suggest that this spread, and indeed the spread of crop cultivation generally, varied in its pace, with ‘delays’ at certain points along its route. Such delays in the spread of agriculture have been explained as resulting from the slow assimilation of agricultural practices by existing indigenous human populations or as the time taken for the crops to adapt to novel climatic conditions, such as altered temperature regimes and day-lengths. A mutant form of the photoperiod response gene, Ppd-H1, causes barley to be non-responsive to long days, while the wild-type responsive form allows plants to flower in response to long days. We sequenced this gene in 65 ‘historic’ barley accessions, from the late 19th and early 20th centuries, in order to explore the potential role of environmental adaptation in the spread of agriculture. We chose to use ‘historic’ material, to complement the richer patterns in extant genetic lines, by spreading the data range in both time and space. Our ‘historic’ barley data shows a latitudinal divide in the Ppd-H1 gene similar to that found in extant lines, but with clearer geographical resolution, and extending northwards into the Arctic Circle. We discuss the implications of our results in relation to the dynamics of agricultural spread across Europe.

Managing flood risk in the UK: towards an integration of social and technical perspectives

In recent years, an apparent increase in the frequency and severity of floods in the UK has led to growing concerns about societal exposure and vulnerability to flooding, particularly in the context of climate change, floodplain development and changing insurance practices. Despite the important link between assessments of exposure to flooding (hazard assessments) and issues of societal vulnerability, this link has rarely been explored in detail and has often been reflected in policy terms by a highly technocratic approach to flood risk management. Indeed, more comprehensive studies have usually favoured rigid and deterministic definitions of vulnerability, in keeping with the wider technocratic paradigm pervading management institutions. In an attempt to redress the balance, this paper considers the role of hazard assessment and issues of societal vulnerability as mutually informative debates and advocates a movement away from the technocratic ideals currently favoured in the UK.

Clam growth-stage profiles as a measure of harvest intensity and resource management on the central coast of British Columbia

Examination of growth-stage profiles of shells from nine Northwest Coast shell midden sites shows a majority of senile-stage shells at longer-term residential sites and a majority of mature-stage shells at shorter-term encampments. This pattern indicates less intensive harvest in the vicinity of residential sites, which is consistent with management and conservation of resources for anticipated future needs. Consideration of environmental and taphonomic factors does not account for the observed inter-site variability. Shellfish conservation in the vicinity of residential sites is evident for the period of the past 7000 years.     

New public management and welfare-to-work in Australia: Comparing the reform agendas of the ALP and the Coalition

Since the 1990s, the adoption of new public management (NPM) as a management philosophy has translated into multiple waves of reform in the employment services sector in Australia, namely Working Nation (1994–96), Job Network (JN: 1996–2009) and Job Services Australia (JSA: 2009–present). Each wave has sought to improve the preceding policy. In this article, we examine changes implemented during the Rudd/Gillard Labor governments. Using government policy documents and survey data from frontline employment services staff, we compare JSA to JN against five benchmarks. Our data indicate that JSA has generated modest improvement. JSA is also a system with less emphasis on strong forms of sanctioning. Our combined data suggest that policy actors operating under NPM conditions are indeed able to influence specific aspects of frontline practice, but they must spend great effort to do so and must accept new imperfections as a consequence.

1990年代以来,新型公共管理被作为一种管理哲学而被接受。这导致了就业服务部门的数次改革浪潮,即工作国（1994—96）、工作网（1996—2009）、澳大利亚工作服务（2009至今）。每波浪潮都力图改良此前的政策。本文考察了陆克文/吉拉德工党执政时期的变革。作者根据政府的政策文件、一线就业服务机构员工的调查数据等等,在五个基准点上将澳大利亚工作服务与工作网做了对比。根据我们的资料,澳大利亚工作服务这个系统带来的改进最小,也不大注重强有力的制裁。我们认为,实施新型公共管理的政策制定方的确能影响一线实践的某些方面,但他们还要花大力气,还要接受往后新的不圆满。     

An approach to mapping buried prehistoric palaeosols of the Atlantic seaboard in Northwest Europe using GPR, geoarchaeology and GIS and the implications for heritage management

Widespread layers of well-preserved organically and archaeologically rich palaeosols dating to the Bronze Age and Iron Age are known from across the Atlantic seaboard of Scotland, including the Western Isles, Orkney and Shetland. The survival of these soils has been facilitated by an overburden of Aeolian sand forming dunes above them. Whilst these soils display archaeological importance, they are constantly under threat from erosion through storm damage due to their exposed coastal position. This presents certain challenges with regard to heritage management, since their extents are largely unknown, normally only being identified when exposed by wind and storm erosion. Consequently, following such damage mitigation can only be reactionary in response to archaeological deposits being uncovered, and left open to threat, Without accurately mapping the extent of these important deposits, archaeological landscape management is compromised.This paper presents a case study aimed at enabling proactive management of these deposits through rapid three-dimensional mapping undertaken using a combination of borehole-calibrated GPR survey and GIS modelling. The results demonstrate how effective baseline data can be generated to highlight areas of greater or lesser risk thereby providing the potential for quantifying and predicting the effects of damage from future storm events.     

New radiometric dating of water management features at the prehistoric Purrón Dam Complex,Tehuacán Valley,Puebla, México

Recent investigations at the prehistoric Purrón Dam Complex in the Tehuacán Valley of southern Puebla, México applied radiometric dating to more securely date the complex. Ceramic-based dating in the 1960′s placed the Dam's origin to the Formative Period. While Formative Period origins are widely accepted, the chronology lacks resolution and direct dates. Samples from impounded sediments behind the dam and from prehistoric canal fill were dated through Optically Stimulated Luminescence (OSL) as well as both standard ¹⁴C and accelerated mass spectrometry (AMS) assays. These samples directly date the functioning of the water management features within the complex. The results confirm the Formative Period origins of the Purrón Dam, and offer new insights into the construction and functioning of the dam and irrigation system.
