Eine systematische Übersicht über Fragebögen aus Lärmwirkungsstudien

In Fragebogen-Untersuchungen zur Lärmwirkung wurden bisher sehr unterschiedliche Operationalisierungen von Wirkungsvariablen (wie z.B. Belästigung, Störung von Aktivitäten) und außer-akustischen Faktoren (sog. Moderatoren wie z.B. Lärmempfindlichkeit, misfeasance) verwendet. Deshalb hat sich die Arbeitsgruppe community response der International Commission on the Biological Effects of Noise (ICBEN, Team No. 6) als langfristiges Ziel die Entwicklung von Fragebogen-Guidelines und die Formulierung eines Muster-Fragebogens für die Lärmwirkungsforschung gesetzt. D.h. es soll ein Vorschlag erarbeitet werden, in welcher Form globale und spezifische Lärmwirkungen in Befragungen erhoben werden sollten. Um dieses Vorhaben zu unterstützen, hat der Arbeitskreis Ökologische Lärmforschung die Erstellung einer systematischen Übersicht über vorhandene Fragebögen aus Lärmwirkungsstudien auf internationaler Ebene in Angriff genommen. Diese Übersicht soll es u.a. ermöglichen, die Struktur von verschiedenen Fragebögen sowie die in ihnen verwendeten Operationalisierungen für Lärmwirkungs- und Moderatorvariablen (hinsichtlich Art der Frageformulierung sowie der Antwortformate) zu vergleichen. Für den/die einzelne/n Lärmforscher/in bietet diese Übersicht die Möglichkeit, sich auf sehr effiziente Art und Weise darüber zu informieren, wie bestimmte Konstrukte in bisherigen Untersuchungen operationalisiert worden sind bzw. welche Alternativen zu den bereits selbst angewandten Operationalisierungen bestehen. Nach einer systematischen Ermittlung von Namen und Adressen einschlägiger Lärmforscher/innen, wurden diese um die Zusendung von Fragebögen sowie ergänzender Materialien aus eigenen Lärmwirkungsstudien gebeten. Die zugesandten Fragebögen werden gegebenenfalls übersetzt und mit der Methode der qualitativen Inhaltsanalyse ausgewertet. Hierbei werden die Fragebögen im Hinblick auf formelle Aspekte (z.B. Jahr der Erhebung, Sprache, Art der Befragungsmethode) wie auch im Hinblick auf strukturelle Aspekte (z.B. Umfang des Fragebogens, abgefragte Variablengruppen, Antwortformate) ausgewertet. Hauptgegenstand der Auswertung ist aber insbesondere die Auswertung der Lärmwirkungsvariablen (z.B. die Abfrage der globalen Lärmbelästigung, Aktivitätenstörungen, Kommunikationsstörungen) sowie der Moderatorvariablen (z.B. Lärmempfindlichkeit, Lärmbewältigungsvermögen, misfeasance). Parallel dazu wurde eine Datenbank entwickelt, in der die Ergebnisse der Analysen dargestellt und verwaltet werden. Diese Datenbank wird ab November 2001 im Internet unter http://www.eco.psy.ruhr-uni-bochum.de/nqd für jede/n interessierte/n Forscher/in zugänglich und nutzbar sein. Langfristig ist darüber hinaus geplant, ein Archiv mit den Original-Fragebögen aufzubauen, in dem einzelne Fragebögen auf Wunsch eingesehen werden können.

ERA-NET - Development of test methods for non wood small-scale combustion plants

Non wood fuels for small-scale furnaces have attracted increasing interest in several European countries. New technological approaches are on the way, but the verification of any such developments is difficult and there is a large uncertainty about testing procedures and equipment. While for wood combustion standardized European measuring regulations are available and broadly applied, the testing of cereal fuel combustion is generally not following a commonly accepted procedure. Consequently the results of such measurements are not fully comparable. This applies particularly for the international level, which is here of particular relevance due to the fact that a combustion technology development for a niche application can only be economically viable if a sufficiently large marketing area can be taken into focus. The overall objective of the proposal is therefore to contribute through research to the development of uniform and comparable European procedures for testing of small-scale boilers up to a power out of 300 kW for solid biomass from agriculture like straw pellets and energy grain. The driving forces and barriers will be worked out; existing legal regulation for the installation (approval by the local authorities) in the participating countries will be collected. The state of the art of the non wood biomass boiler technology will be identified; the need for standardized tests for type approval tests and the measures to establish a European Standard will be shown. Measurement methods with special emphasis on efficiency and emissions will be worked out and the requirements and specifications of test fuels will be proposed. Test runs will be carried out following preliminary test procedures based on existing European standards for wood boilers. Based on the results of these test runs a draft for a Europe-wide uniform test procedure will be proposed. Preparatory work for a European standardization process including a round robin test will be done.

Resolving the impact of climatic processes on ecosystems of the North Atlantic basin and shelf seas: Integrating and advancing observation, monitoring, and prediction (BASIN)

The scale of influence of global change and the added value of co-ordinating the scientific activities of the EU and North American countries to assess, predict and mitigate the effects on marine ecosystems of the North Atlantic and their services is the justification for the development of the BASIN SSA. An important step towards such a co-ordinated approach is the development of an implementation plan where by jointly funded international projects can be supported. The development of such a plan is the first key goal of BASIN. The second goal of BASIN is to develop an integrated basin-scale North Atlantic research program, for submission to the EU 7th framework program, US NSF and Canadian NSERC for joint funding. Programmatic goals will be achieved in working groups including experts from both the EU and North America as well as delegates from funding organisations. As a prerequisite for the development of the research proposal, this SSA will (1) assess the status of climate related ecosystem research in the North Atlantic basin and associated shelf seas, (2) identify gaps in systematic observations and process understanding of atmospheric and oceanic parameters, (3) identify the potential for consolidation of long-term observations from EU and international databases for modelling and prediction. The BASIN research program will focus on: Resolving the natural variability, potential impacts and feedbacks of global change on the structure, function and dynamics of ecosystems; Improving the understanding of marine ecosystem functioning; Developing ecosystem based management strategies. Hence, BASIN will contribute significantly to the Global Earth Observation System of Systems (GEOSS) 10-Year Implementation Plan via the development of comprehensive, coordinated, and sustained observations of the Earth System, improved monitoring of the state of the Earth, increased understanding of Earth processes, and enhanced prediction.

Feasibility study on means of combating forest dieback in the European Union

All EU Member States face economic and ecological losses due to forest damages. Thus, combating forest dieback, as for example caused by climate change, is a contribution to human safety and well-being and the sustainable development of Europe. The Feasibility Study on means of combating forest dieback in the European Union was initiated by the European Parliament demanding the European Commission to develop a concrete proposal for preventing, mitigating and control forest dieback in the EU. The study was carried out by the Institute for World Forestry and the European Forest Institute (EFI) in 2007. The main objectives of the study were to: - review the different factors affecting forest dieback in the EU and their related causes, - analyse and evaluate the effectiveness of available EU legislations and instruments to combat forest dieback in the EU and - examine the possibilities for establishing a specialised entity for forest protection. In the scope of the feasibility study a survey was conducted in the EU Member States on the importance of damaging agents in EU27 forests. The results of the survey show that the importance of individual threats to forest ecosystem health and vitality varies within European regions. Insects, storm/windfall, and fire were regarded as the most serious threats in Central Europe, Western Europe and Southern Europe respectively. Regional differences exist in relation to damage types and intensity, which thus reflect the importance for particular instruments to prevent, mitigate and control various causes of forest dieback. The feasibility study showed that at the EU level several efficient and well established measures have been implemented which contribute to the prevention, mitigation and control of forest dieback. The study showed also that as a consequence of the current state and the predicted development of environmental pressures, such as climate change, future activities on the EU level to combat forest dieback are urgently needed. Existing measures have to be further developed in order to (a) increase synergy effects between individual instruments, (b) make the instruments more transparent to the entire range of potential stakeholders and beneficiaries, and (c) improve the communication between the different actors involved. A major challenge will be to incorporate future patterns of forest dieback, into existing, amended or new measures. Only the triad of prevention, mitigation and control will put the EU into a position to maintain and enhance the multiple, beneficial functions of forests and their contribution to the quality of life.

FP6-SUSTDEV, International Action for Sustainability of the Mediterranean and Black Sea EnvirOnmeNt (IASON)

Under the 2003 EU Greek presidency, cooperation with Balkan countries on environmental issues was identified as a priority of the EU/Balkan Action Plan. Large-scale co-operation is essential for effective action in the vulnerable Mediterranean and Black Sea coastal zones. During the last 50 years both areas suffered major changes; as semi-enclosed basins, both Seas are ultra-sensitive to anthropogenic stress and to climate change. An EU Presidency Conference on Sustainable Development in the Mediterranean/Black Sea (May 2003), revealed major gaps in management structures, scientific strategies and identified a diversity of environmental issues to be resolved through priority-focused RTD cooperation. Yet, while pressure on the resources of the two seas increases and the potential impact of climate change on coastal and deep-sea resources remains unknown, the two seas have never been jointly studied as systems of interacting basins and ecosystems. The proposal outlines collaboration and clustering schemes involving environmental, economic and scientific organisations in Mediterranean, Black Sea and other EU nations, in order to create synergies in networking and exchanges at several levels, addressing for the first time the system of interconnected basins as one, based on the integration of, both horizontally and vertically, natural scientists and economists. These will: 1) Create an international, interdisciplinary platform coordinating the region's scientific potential in order to prepare RTD projects, based on a Science Plan for the region, securing sustainable development; 2) Focus on natural and anthropogenic pressures exerted upon the functioning of the ecosystem; 3) Reinforce RTD capacity by setting up an environment/resource monitoring network in the light of existing observation networks of different scopes.

Schwerpunktprogramm (SPP) 1176: Climate and Weather of the Sun-Earth-System (CAWSES); Klima und Wetter des Systems Sonne/Erde, SOLEIL: Solar variability and trend effects in layers and trace gasesin the upper atmosphere

Various layers exist in the summer mesosphere at middle and polar latitudes which owe their existence to water ice particles. These layers are called ‚noctilucent clouds' (NLC), ‚polar meso- sphere clouds' (PMC), and ‚polar mesosphere summer echoes' (PMSE) which reflects different observation geometry or entirely different physical processes involved. These layers are very sen- sitive to temperature (and to a lesser extent to H2O) and are therefore best suited to indicate long term and solar cycle changes. Indeed, variations on decadal time scales of different layer parameters (occurrence frequency, layer brightness etc.) have been reported from ground and satellite based observations. However, the physical and photo-chemical processes involved are not understood and some of the observations contradict expectations. In this proposal we want to study the long term (decadal scale) formation of layers in the polar summer mesopause region, in particular their sensitivity to variations of background conditions caused by solar forcing and anthropogenic increase of greenhouse gases. We investigate and complement the available observations on layers (NLC/PMC/PMSE) and trace gases (ground based microwave and satellite observations of H2O) and perform model calculations with the LIMA GCM model. In the third phase of the SPP we want to study in particular the feed back mechanisms of ice formation on the atmosphere (e. g., through freeze drying) and the coupling mechanisms to above and below.

Health effects of indoor pollutants: integrating microbial, toxicological and epidemiological approaches (HITEA)

Objective: Healthy housing and good indoor air quality are important goals of public health. However, biological indoor pollution due to dampness, moisture and mold is an emerging environmental health issue, as recognized in EU indoor air policy documents. Prevalence of dampness is remarkable, and may still increase due to demands of energy savings and extreme weather periods and floods associated with climate change. The exposure may lead to long-term impacts such as asthma. The documentation is strong on association between building mold and health, but the causative agents and disease mechanisms are largely unknown, which impedes recognition of a mold-affected patient in health care. Efficient control and regulation are hampered by the insufficient understanding of these causalities. Understanding of the links between building practices and health is lacking. There is an urgent need for European-wide knowledge to form a basis for establishing building-associated criteria for healthy indoor environments. The aim of this proposal is to clarify the health impacts of indoor exposures on children and adults by providing comprehensive exposure data on biological and chemical factors in European indoor environments.

Coordination of national environment and health research programmes - environment and health ERA-NET (ERA-ENVHEALTH)

Objective: It is estimated that around 20Prozent of the burden of disease in industrialized countries can be attributed to environmental factors, and the magnitude of the problem is perceived by the majority of Europeans. The assessment of health impacts is based mostly on scarce exposure data and limited information on the relationship between exposure and health. There is, therefore, a need to strengthen research in this area and to develop methods and tools which will improve the comparability of data. Member States have developed skills and expertise using different mechanisms to fund environment and health research. The scientific boundaries created by the remits of different funding organisations have frequently acted as a disincentive to collaborative working. Although aims are towards relevance and efficiency, the results remain dispersed and not of actual support for policy-making. Therefore, results of the studies in ERA-ENVHEALTH will lead to the proposal of a coherent set of proposed priorities, implementation of joint activities, and common calls. ERA-ENVHEALTH, by bringing together 16 participants from 10 countries, will contribute to establish collaboration among the different funding organisations of environmental and public health research communities.

Schwerpunktprogramm (SPP) 1158: Antarctic Research with Comparable Investigations in Arctic Sea Ice Areas; Bereich Infrastruktur - Antarktisforschung mit vergleichenden Untersuchungen in arktischen Eisgebieten, Comparison of Arctic and Antarctic microbial communities: abundance, phylogeny and ecology

In the scope of the planned project the diversity and ecology of microbial communities and their functions in nutrient turnover under the extreme conditions in Arctic and Antarctic periglacial environments will be studied. Polar regions are vast and unique natural laboratories, both because of their geographical isolation and the minor anthropogenic influences active there, for studying microbial life under extreme environmental conditions. For this purpose the diversity and abundance of the microflora in dependence of important site characteristics such as hydrological, thermal and weathering processes will be investigated in different habitats on Store Koldewey (East Greenland) and Livingstone Island (Antarctic). The main objectives are the genotypic and phenotypic characterization of the microbial community by cultivation-independent methods such as lipid profiling and rRNA-based analyses. Stable isotope probing will be used to identify the main microbial players in nutrient turnover in the different environments. The acquired data will give insights into the early stage of life on Earth, the development of extreme habitats and the functioning of microbes within the ecosystem. The planed study contributes to the research topics of the International Polar Year proposal entitled Antarctic and sub-Antarctic Permafrost, Periglacial and Soil Environments (ANPAS, No. 627) leaded by Dr. Jan Boelhouwers.
