Development-led archaeology in north-west Europe

Many countries in northern Europe have seen a huge expansion in development-led archaeology over the past few decades. Legislation, frameworks for heritage management and codes of practice have developed along similar but different lines. The Valetta Convention has had considerable impact on spatial planning and new legislation on archaeological heritage management within EC countries as well as on the funding, nature and distribution of archaeological fieldwork. For the first time these 12 papers bring together data on developer-led archaeology in Britain, Ireland, France, the Low Countries, Germany and Denmark in order to review and evaluate key common issues relating to organisation, practice, legal frameworks and quality management.

The vertical cloud structure of the West African monsoon: a 4 year climatology using CloudSat and CALIPSO

The West African summer monsoon (WAM) is an important driver of the global climate and locally provides most of the annual rainfall. A solid climatological knowledge of the complex vertical cloud structure is invaluable to forecasters and modelers to improve the understanding of the WAM. In this paper, 4 years of data from the CloudSat profiling radar and CALIPSO are used to create a composite zonal mean vertical cloud and precipitation structure for the WAM. For the first time, the near-coincident vertical radar and lidar profiles allow for the identification of individual cloud types from optically thin cirrus and shallow cumulus to congestus and deep convection. A clear diurnal signal in zonal mean cloud structure is observed for the WAM, with deep convective activity enhanced at night producing extensive anvil and cirrus, while daytime observations show more shallow cloud and congestus. A layer of altocumulus is frequently observed over the Sahara at night and day, extending southward to the coastline, and the majority of this cloud is shown to contain supercooled liquid in the top. The occurrence of deep convective systems and congestus in relation to the position of the African easterly jet is studied, but only the daytime cumulonimbus distribution indicates some influence of the jet position.

NATO's security discourse after the Cold War: representing the West

This book provides a critical investigation into the discursive processes through which the North Atlantic Treaty Organisation (NATO)reproduced a geopolitical order after the end of the Cold War and the demise of its constitutive enemy, the Soviet Union.

Safeguarding livelihoods or exacerbating poverty?: Artisanal mining and formalization in West Africa

In recent years, policy mechanisms to support a formalized artisanal and small-scale mining (ASM) sector in sub-Saharan Africa have gained increasing currency. Proponents of formalization argue that most social and environmental problems associated with the sector stem from the fact that ASM is predominantly unregulated and operates outside the legal sphere. This paper critically examines recent efforts to formalize artisanal and small-scale mining inWest Africa, drawing upon recent fieldwork carried out in Sierra Leone, Ghana and Mali. In exploring the sector’s livelihood dimensions, the analysis suggests that bringing unregulated, informal mining activities into the legal domain remains a considerable challenge. The paper concludes by confirming the urgent need to refocus formalization strategies on the main livelihood challenges and constraints of small-scale miners themselves, if poverty is to be alleviated and more benefits are to accrue to depressed communities in mineral-rich regions.

'Your secret language': classics in the British colonies of West Africa

What were the cultural politics of classics in British colonies? Did classical education operate as a sign of oppression, or as a tool for forging an anti-colonial politics? Why did Europeans bring the classics to West Africa, and how did they manage the developing dynamic when West Africans laid independent claim to the classical heritage? This ground-breaking study examines the ways in which European colonisers and West African nationalists clashed, or collaborated, over the uses of Latin, Greek and the classics.

Beyond the caves: the Palaeolithic rivers of south-west Britain

This paper introduces a new English Heritage (Aggregates Levy Sustainability Fund) project The Palaeolithic Rivers of South-West Britain (project no. 3847), and summarises the results of a first phase resource assessment. The goal of this ongoing project is to develop a new synthesis of the Lower and Middle Palaeolithic occupation of the south-west region, focusing upon river terrace-based archaeology and its implications for hominin landscape use. The resource assessment has reached two preliminary conclusions. Firstly that the region’s earliest Palaeolithic archaeological record is significantly richer than previously believed, and secondly that although find locations have been added in several areas which previously had very few or no finds (e.g.West Cornwall) the overall bias of finds to the south coast is maintained. The project has also revealed that the river terrace resource of South-West England offers potential for geochronological dating, landscape reconstruction, and improved contextualisation of the archaeological material. Some outreach components of the project are also summarised.

Flooding tolerance in four 'Garrigue' landscape plants: implications for their future use in the urban landscapes of north-west Europe?

Within a changing climate, Mediterranean ‘Garrigue’ xerophytes are increasingly recommended as suitable urban landscape plants in north-west Europe, based on their capacity to tolerate high temperature and reduced water availability during summer. Such species, however, have a poor reputation for tolerating waterlogged soils; paradoxically a phenomenon that may also increase in north-west Europe due to predictions for both higher volumes of winter precipitation, and short, but intensive periods of summer rainfall. This study investigated flooding tolerance in four landscape ‘Garrigue’ species, Stachys byzantina, Cistus × hybridus, Lavandula angustifolia and Salvia officinalis. Despite evolving in a dry habitat, the four species tested proved remarkably resilient to flooding. All species survived 17 days flooding in winter, with Stachys and Lavandula also surviving equivalent flooding duration during summer. Photosynthesis and biomass production, however, were strongly inhibited by flooding although the most tolerant species, Stachys quickly restored its photosynthetic capacity on termination of flooding. Overall, survival rates were comparable to previous studies on other terrestrial (including wetland) species. Subsequent experiments using Salvia (a species we identified as ‘intermediate’ in tolerance) clearly demonstrated adaptations to waterlogging, e.g. acclimation against anoxia when pre-treated with hypoxia. Despite anecdotal information to the contrary, we found no evidence to suggest that these xerophytic species are particularly intolerant of waterlogging. Other climatic and biotic factors may restrict the viability and distribution of these species within the urban conurbations of north-west Europe, but we believe increased incidence of flooding per se should not preclude their consideration.

The re-identification of great bustard (Otis tarda) from Fishbourne Roman Palace, Chichester, West Sussex, as common crane (Grus grus)

This paper details the results of recent reanalysis of the animal remains from the 1960s excavations at Fishbourne Roman Palace, West Sussex. It argues that specimens originally identified as belonging to the great bustard are, in fact, misidentified remains of common crane. This discovery has important connotations. First, these findings need to be reported so that the avian archaeological record can be updated to avoid future syntheses of Romano-British faunal remains incorrectly including great bustard. Secondly, interpretations of the zooarchaeological remains at Fishbourne Palace will alter, due to the differing ecological histories of bustards and cranes.
