Urban geo-archaeology in medieval alzira (Prov. Valencia,Spain)

Alzira is situated in a cut-off meander loop of the Rio Júcar. Geo-archaeological study shows that the Islamic city wall was built during the second quarter of the 11th century AD, at a time when the river had a low-amplitude and low-energy flood regime. After mid-century, overbank silts began to invade the city as peak flood discharge increased, with a spate of destructive floods reflected by high-energy deposits during the late 11th century. Urban expansion within the city wall is dated to the later 11th or early 12th century, interrupted by local abandonment and moderate-energy flood silts. Major construction during the mid-12th century was followed by protracted abandonment (after a siege in AD 1171?) and further, moderate-energy flood silts that redistributed occupation and collapse debris. Reoccupation, during the late 14th century, was terminated by catastrophic floods in 1517 and 1571, after which much of the western end of Alzira was not rebuilt. Following further flood catastrophes during the 17th century, parts of the central walled city remained abandoned until the 19th century. with new occupation atop flood sands of yet another disaster in 1864. The change in flood regime after 1150 was a result of deforestation of the watershed, but progradation of a downstream tributary fan after 1517 created an unstable, aggrading floodplain increasingly prone to severe flooding. Climatic anomalies were responsible for periods of recurrent severe floods, archaeologically verified during the 11th and 12th centuries, and historically documented, beginning in 1318. The geo-archaeological methodology illuminates the constructional and settlement history of Alzira, allows distinction of fluvial and cultural components, and provides the necessary microstratigraphic detail and dating control to document the true complexity of alluvial processes during the last 1000 years.     

A Ticking Clock? Preservation and Management of Greenland’s Archaeological Heritage in the Twenty-First Century

ABSTRACT

Evaluating the rate of deterioration at archaeological sites in the Arctic presents several challenges. In West Greenland, for example, increasing soil temperatures, perennial thaws, coastal erosion, storm surges, changing microbial communities, and pioneer plant species are observed as increasingly detrimental to the survival of organic archaeological deposits found scattered along the country’s littoral zones and extensive inner fjord systems. This article discusses recent efforts by the REMAINS of Greenland project for developing a standardised protocol that defines the archaeological state of preservation, the preservation conditions, and asset value of organic deposits. Special emphasis is given to the degradation of materials such as bone and wood that are historically observed to be well-preserved in Greenland but now currently at risk. The protocol provides a baseline for monitoring future changes and will assist archaeologists in Greenland with a procedure for documenting and predicting areas of increasing vulnerability due to a warming climate.     

The reasons of Europe: Edmund Husserl,Jan Patočka,and María Zambrano on the spiritual heritage of Europe*

ABSTRACT

This article investigates the genuinely philosophical engagement with the idea of Europe twentieth century philosophy. Here, especially phenomenology has developed a distinct tradition of conceiving Europe not as a geographical and political entity but rather as a ‘spiritual shape.’ Husserl, as the originator of this thought, traces this spiritual Europe back to Ancient Greece of the 7/6 century B.C. in which an unprecedented ‘theoretical attitude’ towards the world originated. Hence, Europe is conceived as a project of reason, of pure rationality while at the same time leaving out the constitutive dimension of religion. Furthermore, this non-historical philosophical genealogy proves itself to be an arbitrary but intentional genealogy whose intentions have to be put into critical reconsideration. In this article, I will introduce Pato?ka and Zambrano as important critiques of Husserl’s genealogy, or even potentially violent mono-genealogy, as Derrida has emphasized. Following Foucault, it is the aim of this article to put into question the myth of a single historical-political origin of Europe’s spiritual heritage and furthermore to pay attention to the transformations and conflictual relations between Europe’s different forms of reason and religion.     

An alternative approach to zoning in France: Typology,historical character and development control

The paper describes an approach to development control taken in France, bringing together the zoning system of planning and geographical and architectural studies of urban form. The approach addresses a number of issues, in particular the maintenance of the historical and regional character of towns, often eroded under systems of land‐use zoning. The principles and methods of the approach are set out and its application is illustrated by an example, illuminating both the approach and the context in which it was realized.
