The European spatial development perspective and North‐West Europe: application and the future1

The European Spatial Development Perspective (ESDP) is the product of a north‐west European planning tradition. This article discusses the role of north‐west European concerns, in particular the use of the concept of polycentricity, in the making of the ESDP, and the application of the ESDP in the North‐west European Metropolitan Area (NWMA), more in particular in Germany, the UK, The Netherlands and Belgium. The article also explores the future of spatial planning as regards north‐west Europe. Much will depend on how Community policy will adapt to the enlargement of the European Union. However, it seems certain that existing member states, in particular those in north‐west Europe will see their share in the structural funds evaporate. This may give added significance to INTERREG IIIB respectively to the successor of this Community Initiative. In addition, concepts like territorial cohesion and territorial management may become functional equivalents to that of spatial planning, for which the Community is said to have no competence.     

Cave Art in Context: Methods for the Analysis of the Spatial Organization of Cave Sites

Investigations of prehistoric cave art have long neglected the surrounding context: space, archaeological objects, and imprints. As a result, an integrative structural approach that analyzes cave art as part of an anthropomorphized landscape has not been available. This article draws on urban planning and the physiology of the human eye to provide an innovative archaeospatial analysis of cave sites. A set of relevant features from the caves of Bédeilhac, Fontanet, and Le Portel was selected and defined (light zone, chamber type, path network, mode of movement, and available space). An analysis of the prehistoric remains in the caves allows the reconstruction of different concentrations of human activities (cave art, archaeological objects, and imprints). The projection of these concentrations onto the structured map of the caves results in four types of locations: drawing location, supply location, drawing location with substantial activities, and drawing location with consumption activities. This approach opens new avenues for the archaeological perception of caves and their inhabitants: Upper Paleolithic humans were very familiar with caves and probably followed a master plan during their stay in the dark.     

Humans,climate or introduced rats – which is to blame for the woodland destruction on prehistoric Rapa Nui (Easter Island)?

When the first Polynesian settlers arrived on Rapa Nui, about 70% of the island was covered with dense woodland in which Jubaea palms dominated. Our investigations of extended soil profiles provide evidence that more than 16 million palm trees grew on the island. Nearly all palms were removed by the 16th century. Teeth marks on nutshells of the Jubaea palms from the 13th or 14th centuries attest to the activity of Pacific rats (Rattus exulans) on Rapa Nui, which were probably imported there by the first Polynesians settlers. Did the rats perhaps prevent the germination of palm seeds and thus the regeneration of the dense palm woodland of Rapa Nui?
