Der Weg zum Flussgebietsmanagement

Zusammenfassung Der Flussgebietsansatz ist ein zentrales Element der Wasserrahmenrichtlinie (WRRL) und wurde in Deutschland im Zuge der organisatorischen Umsetzung der Richtlinie strukturell implementiert. Die Kooperationsstrukturen auf Flussgebietsebene sollen dabei einen funktionierenden Rahmen auch für die fachliche Umsetzung der Richtlinie bilden. Beim dazu erforderlichen strukturellen Wandel waren insbesondere die in den Flussgebieten bereits vorhandenen Kooperationsstrukturen von Bedeutung. Diese wurden entweder ausgebaut, umstrukturiert oder von neuen Strukturen zur Umsetzung der WRRL überlagert. Die dabei zum Teil entstandenen Doppelstrukturen erh?hen jedoch den Koordinierungsaufwand der Akteure stark, so dass es aktuell zu einer Zusammenführung und Konsolidierungsbewegung kommt. Allerdings wird auch nach der Konsolidierung eine gro?e strukturelle Vielfalt in den Flussgebieten verbleiben, die durch eine enge Zusammenarbeit der Akteure zu bew?ltigen ist. Es bleibt abzuwarten, inwiefern diese Strukturen sich auch eignen, um neuen Herausforderungen, wie beispielsweise den Folgen des Klimawandels, zu begegnen.     

Modern humans in Sarawak,Malaysian Borneo,during Oxygen Isotope Stage 3: palaeoenvironmental evidence from the Great Cave of Niah

During recent reinvestigations in the Great Cave of Niah in Borneo, the ‘Hell Trench’ sedimentary sequence seen by earlier excavators was re-exposed. Early excavations here yielded the earliest anatomically-modern human remains in island Southeast Asia. Calibrated radiocarbon dates, pollen, algal microfossils, palynofacies, granulometry and geochemistry of the ‘Hell Trench’ sequence provide information about environmental and vegetational changes, elements of geomorphic history and information about human activity. The ‘Hell’ sediments were laid down episodically in an ephemeral stream or pool. The pollen suggests cyclically changing vegetation with forest habitats alternating with more open environments; indicating that phases with both temperatures and precipitation reduced compared with the present. These events can be correlated with global climate change sequences to produce a provisional dating framework. During some forest phases, high counts of Justicia, a plant which today colonises recently burnt forest areas, point to fire in the landscape. This may be evidence for biomass burning by humans, presumably to maintain forest-edge habitats. There is evidence from palynofacies for fire on the cave floor in the ‘Hell’ area. Since the area sampled is beyond the limit of plant growth, this is evidence for human activity. The first such evidence is during an episode with significant grassland indicators, suggesting that people may have reached the site during a climatic phase characterised by relatively open habitats ∼50 ka. Thereafter, people were able to maintain a relatively consistent presence at Niah. The human use of the ‘Hell’ area seems to have intensified through time, probably because changes in the local hydrological regime made the area dryer and more suitable for human use.     

Concentrated Urban Poverty: The Case of Izmir Inner Area,Turkey

In Turkey, poverty has been a main subject of debates since 1960s. It used to be a serious problem for both rural areas and the big cities that gained migration. In Turkey and world-wide since the 1980s, however, there have been more research interests in the concentrated urban poverty, especially along with the increase in levels of impoverishment around the world. With the help of a case study in Izmir (Turkey), this paper aims to examine the process of concentrated urban poverty from different points of view in the literature. This is a case study developed at the peripheries of the traditional city centre—or inner areas—of the city of Izmir, Turkey. The paper, first, discusses the parameters of concentrated poverty according to the literature. Then it introduces the study findings of the author, which point out the macro-scale, micro-scale and ecological dynamics that are important in the development of concentrated urban poverty. The macro-scale dynamics suggest that poverty in inner areas of the city are related to the unbalanced development trends within the country, such as the overgrowth of metropolitan cities, economic restructuring processes, migration trends and the development of informal economy. The ecological dynamics address to the housing and job location preferences and invasion-succession processes in the city, which emphasize that socio-economic characteristics of inner areas of the city are different from those of other city parts. Micro-scale dynamics are related to poors' ability of developing solidarity relations among themselves, which is also related to the spatial characteristics of inner areas of the city, according to this study's findings.     

Increasing Role of Services in Competitive Power and Innovativeness of Firms and Industrial Clusters

The aim of this paper is to discuss the importance of different types of global services for industrial firms and clusters in terms of their economic competitiveness and innovative performance. The theoretical debates argue that globalization, deregulation and the new production organization make it necessary to use global services that are supplied easily with the help of new telecommunication technologies. The existing empirical studies provide some supporting evidence. However, they also indicate that global service firms can be attained by only smaller numbers of industrial firms and clusters. Still, in-house services besides temporal and informal mechanisms are important to meet the needs of the specialized services, even for the firms that try to become a part of the global production system. The paper focuses on three main questions: “What types of global services are becoming crucial for manufacturing firms and what type of services are still local and national? Is there a significant difference between the characteristics of firms that use the same type of services? To what extent is having access to global services important for the innovativeness of industrial firms and clusters? This paper looks for the answers to these questions based on existing case studies as well as this study of three industrial clusters in Turkey. The findings indicate that there is not a perfect match between theory and empirical evidence and there is a need for more refined theoretical discourses on industry–service relations.
