Description: Given the variability of seasonal, annual, and in particular langer time-scales, the dispersal and fate of the river discharge and its influence on the hydrographical and sedimentological settings are the central tasks in understanding the Holocene history of the Laptev Sea shelf. The main goal of this study was to investigate short- and long-term environmental changes in the strongly coupled land-shelf system of the Laptev Sea using isotopic evidence in sediments and biogenic carbonates. In order to trace the modern spatial distribution of terrestrial organic matter, which is strongly affected by the riverine input and the thermal erosion of the ice-rich permafrost coast, stable carbon isotope ratios of total organic carbon in surface sediments were analyzed. The stable carbon isotope composition of surface sediments reveal a dominant impact of terrestrial organic matter on the modern depositional environment of the Laptev Sea shelf with distinct south to north and east to west gradients. Based on downcore 8 13Carg records in radiocarbon-dated sediment cores the spatial and temporal deposition of terrestrial organic matter during the past 12.7 ka is specified and can be related to depositional changes which occurred after the last glacial maximum when this region became flooded due to a global rising sea level. The major changes in the deposition of terrestrial organic matter occurred between 11 and 7 ka BP and comprise the main phase of the southward retreat of the coastline and river depocenters due to the postglacial sea level rise. Stable oxygen and carbon isotope profiles from recent and fossil bivalve shells were investigated in order to trace modern and past hydrographical conditions and their changes during the postglacial history of the Laptev Sea. The serial dissection of bivalve shell valves along their growth axis from the umbo towards the ventral margin provides an isotopic record of hydrographical and physiological changes during the life of the individual specimen. The oxygen isotopic profiles of modern bivalve species of Astarte borealis exhibit amplitude cycles interpreted as recording annual hydrographical cycles. Regarding the well-known relationship between the carbonate 8 180, temperature, and the isotopic composition of water (8180w), it is possible to relate isotopic phases to seasonal hydrographical phases like summer and winter. The within shell isotopic variations are mainly attributed to variations in the isotopic composition and in the salinity of bottom waters in the Laptev Sea. Seasonal temperature changes can be regarded of minor importance. Using a modern linear relationship between 8 180w and salinity of 0.50 %0/salinity, salinity records are reconstructed from the oxygen isotope records of the bivalve shells and can be directly compared with hydrographical parameters at the investigated sites. Carbon isotope profiles from modern specimens reveal a correspondence to the river breakup and to seasonal phytoplankton productivity. Trends towards lighter 8 13 C values through ontogeny suggest the effects of metabolic changes from a juvenile into a mature adult. Differences in the 8 13C of shell carbonate between the sites appear to reflect the regional distribution of the ö 13C of sedimentary organic matter. Given a good conformance between isotope profiles from modern bivalve shells and oceanographic observations, oxygen isotope profiles of radiocarbon bivalve shells from a sediment core from northeast off the Lena Delta are usecl to obtain in formation about passt hydrological conditions. Although isotope profiles from fossil bivalves of the Laptev Sea shelf reflect only a brief interval of time, they may offer new important insights into the paleohydrography during snapshots of the last 8.4 ka and their relation to the Holocene transgression. A reconstructed bottom water salinity of 29.5 at 8.4 ka BP indicates that the particular site was much more affectecl by riverine water than nowaclays causecl by the proximity to the coastline and to the paleo-1iver mouth. Due to the continuing southward retreat of the coastline ancl the Lena River mouth relative to the study site an increase in the bottom water salinity at 7.3 ka BP is reconstructecl. The oxygen isotope shell profile at 7.3 ka BP gives an evidence of a bottom water hydrography which is characterized by a high variability of summer and winter conditions on the level of modern bottom water conditions. The following time slices at 3.6 ka and 1.6 ka BP reveal that modern hydrological conditions are fully established. The presented salinity reconstruction enables us to make further presurnptions on the relative proximity of the study site to the coast and to the river rnouth during snapshot views of the Holocene history and thus can be related to the postglacial transgression of the Laptev Sea shelf.

Description: The Joint Global Ocean Flux Study (JGOFS) has completed a decade of intensive process and time-series studies on the regional and temporal dynamics of biogeochemical processes in five diverse ocean basins. Its field program also included a global survey of dissolved inorganic carbon (DIC) in the ocean, including estimates of the exchange of carbon dioxide (CO2) between the ocean and the atmosphere, in cooperation with the World Ocean Circulation Experiment (WOCE). This report describes the principal achievements of JGOFS in ocean observations, technology development and modelling. The study has produced a comprehensive and high-quality database of measurements of ocean biogeochemical properties. Data on temporal and spatial changes in primary production and CO2 exchange, the dynamics of of marine food webs, and the availability of micronutrients have yielded new insights into what governs ocean productivity, carbon cycling and export into the deep ocean, the set of processes collectively known as the "biological pump." With large-scale, high-quality data sets for the partial pressure of CO2 in surface waters as well for other DIC parameters in the ocean and trace gases in the atmosphere, reliable estimates, maps and simulations of air-sea gas flux, anthropogenic carbon and inorganic carbon export are now available. JGOFS scientists have also obtained new insights into the export flux of particulate and dissolved organic carbon (POC and DOG), the variations that occur in the ratio of elements in organic matter, and the utilization and remineralization of organic matter as it falls through the ocean interior to the sediments. JGOFS scientists have amassed long-term data on temporal variability in the exchange of CO2 between the ocean and atmosphere, ecosystem dynamics, and carbon export in the oligotrophic subtropical gyres. They have documented strong links between these variables and large-scale climate patterns such as the El Nino-Southern Oscillation (ENSO) or the North Atlantic Oscillation (NAO). An increase in the abundance of organisms that fix free nitrogen (N-2) and a shift in nutrient limitation from nitrogen to phosphorus in the subtropical North Pacific provide evidence of the effects of a decade of strong El Ninos on ecosystem structure and nutrient dynamics. High-quality data sets, including ocean-color observations from satellites, have helped modellers make great strides in their ability to simulate the biogeochemical and physical constraints on the ocean carbon cycle and to extend their results from the local to the regional and global scales. Ocean carbon-cycle models, when coupled to atmospheric and terrestrial models, will make it possible in the future to predict ways in which land and ocean ecosystems might respond to changes in climate.

Description: Annual catches of Todarodes pacificus in Japan have gradually increased since the late 1980s. Paralarval abundances have also been higher since the late 1980s compared to the late 1970s and mid-1980s. Here is proposed a possible scenario for the recent stock increase based on changing environmental conditions. Based on trends in annual variations in stock and in larval abundances, catches are reviewed and potential spawning areas inferred, assuming that egg masses and hatchlings occur over the continental shelf at temperatures between 15 and 23°C. Changes are then inferred in the spawning areas during 1984–1995, based on GIS data. Since the late 1980s, the autumn and winter spawning areas in the Tsushima Strait and near the Goto Islands appear to have overlapped, and winter spawning sites seem to have expanded over the continental shelf and slope in the East China Sea.

Description: A policy framework for sustainable resource management (SRM) is required both to guarantee the materials and energy supply of the EU economy and safeguard the natural resource basis in the future. Goals and strategies for sustaining the metabolism of the economy are described. Data are presented on the material throughput and physical growth of the EU's economy, on total material requirements (TMR), its composition, the decoupling from economic growth, and the increased shift to other regions. A first future target Material Flow Balance (t- MFB) of the EU is outlined. Detailed data reveal the "top ten" resource flows. Policy design for SRM should aim at an integrated and balanced approach along the material flow, comprising resource extraction, the product cycle and final waste disposal. Strategies and potential instruments to manage fossil fuels, metals and industrial minerals, construction minerals and excavation are discussed. Possible priorities and examples are given for target setting, focusing on limited expansion of built-up area, reduced use of non-renewables, increased resource productivity, and shift to sustainable cultivation of biomass.

Description: Vom 10. bis zum 14. September diesen Jahres verhandelt die Ministerkonferenz der Welthandelsorganisation (WTO) über eine weitere Liberalisierung des Welthandels. Dabei steht für die Umwelt eine Menge auf dem Spiel. Zwar wurden mit der Doha Deklaration in der gegenwärtigen Verhandlungsrunde einige Verhandlungen mit Umweltbezug vereinbart. Dies täuscht aber darüber hinweg, dass die WTO noch weit entfernt davon ist, ökologische Aspekte in ihrer Politik angemessen zu berücksichtigen. Vorliegendes Papier analysiert zunächst die Diskussion über Umweltthemen in der WTO, welche seit über zehn Jahren vor allem im Committee on Trade and Environment (CTE) der WTO geführt wird. Die Analyse zeigt auf, dass zahlreiche Umwelteffekte von Handelsliberalisierungen gar nicht diskutiert wurden, Interessengegensätze zwischen Mitgliedsstaaten der WTO eine tief gehende Diskussion vereiteln und Ansätze einer ökologischen Reform der WTO bislang keine Chance hatten. Vor dem Hintergrund dieser Analyse wird sodann eine doppelte Strategie entwickelt. Erstens wird dargelegt, warum die WTO aufgrund ihrer umweltpolitischen Defizite denjenigen Institutionen ihren Handlungsspielraum lassen sollte, die sich aktiv mit Umweltpolitik beschäftigen. Hierzu wird das Konfliktverhältnis multilateraler Umweltabkommen und der WTO untersucht. Zunächst erfolgt eine Klassifizierung in unbedenkliche und potentiell kritische Konfliktfälle. Dann wird aufgezeigt, wie einerseits eine Begrenzung der Zuständigkeiten des Streitschlichtungsorgans der WTO sowie andererseits kooperative, politisch-rechtliche Prozesse zur Lösung der Konflikte zwischen den betroffenen Institutionen eine Lösung bieten und zu einer größeren institutionellen Gleichheit in der globalen politischen Arena führen könnten. Zweitens wird erörtert, wie ökologische Aspekte Schritt für Schritt in die WTO integriert werden könnten. Hierzu werden Instrumente der strategischen Folgenabschätzung untersucht. Nach einer eingehenden Analyse der Potenziale und Grenzen von strategischen Folgenabschätzungen werden Empfehlungen zu ihrer Weiterentwicklung formuliert. Anschließend werden Möglichkeiten dargestellt, wie strategische Folgenabschätzung in die institutionellen Strukturen der WTO integriert werden könnten, um ökologische Aspekte systematisch in die politischen Entscheidungsprozesse einfließen zu lassen und eine verbesserte Partizipation der Öffentlichkeit an der Politik der WTO zu gewährleisten. Dabei wird einerseits eine Integration strategischer Folgenabschätzungen in den Trade Policy Review Mechanism der WTO und andererseits die Einrichtung eines neuen Strategic Impact Assessment Body innerhalb der WTO diskutiert.

Description: In diesem Wuppertal Paper unternehmen Claudia von Braunmühl und Uta von Winterfeld eine begriffliche Erkundung im Spannungsfeld von Nachhaltigkeit, Globalisierung und Demokratie. Sie beziehen sich vorrangig auf die Arbeiten der Enquete-Kommission des Deutschen Bundestages "Globalisierung der Weltwirtschaft" (2002) und stellen das dort verhandelte Konzept von Global Governance vor sowie seine demokratietheoretische Schwächen. Des weiteren geht es um zwei Denkrichtungen, die den Autorinnen geeignet erscheinen, der politischen Dimension und Problematik von Globalisierungsprozessen gerecht zu werden. In einem Abschnitt über "Nachhaltiges Regieren?" skizzieren sie, entlang welcher Rationalitätsmuster die Demokratiedefizite in Verbindung mit Globalisierung und Nachhaltigkeit verlaufen und verknüpfen diese Überlegungen mit der Debatte, die derzeit zum Themenkomplex "globale öffentliche Güter" geführt wird.

Description: Transnational corporations' (TNCs) economic operations cover numerous countries and can be diverted between several continents. These units have reached a level of significance, having not only economic, but also social and environmental implications. This justifies that they shall be treated separately as a social phenomenon, when considering strategies for the development towards sustainability. This paper presents the concept of Responsible Corporate Governance (RCG), as a strategy to "govern" TNCs. RCG is suggested as a stakeholder based policy instrument, which aims at allocating responsibilities to societal actors aiming at corporate accountability. RCG recognises that the process of societal change is strongly based on what can be called as bottom up-processes. Learning processes take place through the interaction of the different societal members, which eventually leads to macro changes. Therefore, governing TNCs towards sustainability improvements is considered to be a collective process including all stakeholders. Firstly, the paper places the concept of RCG in the ongoing debate of political modernization based on the fact that society develops overtime and the political system must correspondingly modernize. In this context, political overload developed as a consequence of increased resource interdependencies is explained and as a resolution, network approach is discussed. Secondly, demands on the orientation of the TNCs in terms of accountability and innovative action are brought forward. Here, the paper also lists down corporate elements (stakeholder empowered corporate governance, management and performance evaluation systems, transparency enhancement and accountability verification), which need to be in place to attain an accountable orientation in the society. Following, using an analytical framework, the orientation and capabilities of each societal actor (environmental non-governmental organisations, financial institutions, intergovernmental organisations) to affect improvements in the corporate responsibility elements are investigated and recommendations for their effective orientation are listed.
