Impact of long-term exposure to elevated pCO2 on activity and populations of free living N2 fixing organisms in a temperate grassland system

The project aims at achieving a better understanding of the processes that drive or limit the response of grassland systems in a world of increasing atmospheric pCO2. We will test the hypothesis that the previously shown increase in below-ground allocation of C under elevated pCO2 provides the necessary energy excess and will stimulate free-living N2 fixers in a low N grassland environment. The project thus aims at assessing the occurrence and importance of free-living N2 fixers under elevated pCO2 and identify the associated microbial communities involved in order to better understand ecosystems response and sustainability of grassland systems. This project had the last opportunity to obtain soil samples from a grassland ecosystem adapted to long-term (10 year) elevated atmospheric pCO2 as the Swiss FACE experiment. The project aims to identify the relevant components of free-living diazotrophs of the microbial community using 15N stable isotope - DNA probing.

FP6-POLICIES, Identification and assessment of training needs, methods and activities for the wider use of environmental technologies in key sectors (ETTAR)

With a focus on transport, the project intends to increase the understanding among relevant actors of the benefits of environmental technologies for a wider application of these technologies. It will build on the ETAP actions on targeted training and awareness raising. Pursuing this aim, the following support activities will be undertaken: 1) conceptualising and organising of 3 workshops with relevant stakeholders for stock taking, identifying obstacles and possible solutions as well as best practice examples; 2) organising a concluding conference on the basis of experiences made in the course of the project (to produce recommendations); intended for senior executives within the sector in order to ensure that the learning from the project is communicated at a level that can help to ensure as broad a take-up and dissemination as possible. 3) Producing Background Notes and Policy Briefs on training needs and awareness raising. The Background Notes will serve as a basis for the Conference discussions; the Policy Briefs will disseminate the projects findings and recommendations beyond the project to a wider public. 4) Specifying a low-cost, easily disseminated e-learning solution that addresses the overall objective of the project: increasing awareness amongst those working in this sector of underlying issues and dilemmas as well as of solutions and good practice. This activity also includes recommendations for routines to maintain the awareness and competence in order to ascertain continuous, long-term effects of the efforts.

Lightweight amorphous silicon solar panels

Objective: New process route for lightweight, unbreakable and economically feasible solar panels on the basis of amorphous silicon. Results: From a number of canditates enamel-coated steel sheet as substrate and an organic barrier as protective layer was chosen as an alternative to the dual glass panels. Criteria were vacuum compatibility, surface rougness and insulating properties. This concept requires that the production order of the thin film solar cell is reversed into back electrode, active stack, front transparent electrode. Inverted processes and low temperature processes were investigated in parallel. Protection against damage due to permeating water was reduced with an improved organic barrier coating. Also, less vulnerable back electrode materials were studied. Fluorine doped tin oxide, tin-doped indiumoxide and aluminium-doped zinc oxide were studied. However, the best and most economical results were optained with ITO. For monolithic integration mechanical masking and laser scribing were investigated. Mechanical masking failed due to the uneveness of the enamel surface. Laser scribing is possible due to the diminished power need with each consecutive layer. Some concepts for better light capture (texturing, optical coatings) were investigated. Based on the inverted process route small scale and full scale panels were manufactured and tested. Ultimately, the full scale failed due to the built-up of stress which caused delamination and could not sufficiently be reduced. The panel costs of the new route proved very similar to the existing product, but required an additional investment in vacuum deposition equipment. Surprisingly, ITO with recycling proved to be the most cost effective transparent electrode material.

Global Monitoring for Environment and Security (GMES) - GSE Forest Monitoring in Russia (Stage II), Global Monitoring for Environment and Security (GMES) - GSE Forest Monitoring in Russia (Stage I)

This GSE-FM service option provides a powerful tool for effective forest monitoring and inventory at regional scale using both EO-data and ground based observations. It is especially designed for allocating reliable and up-to-date information over large forest areas. Many regions of the world like wide parts of Russia and the Irkutsk Oblast are covered by vast forests. The countries and administrative regions often have to deal with pressing environmental problems such as frequent forest fires events, illegal logging practices as well as other human activities and natural forest disturbances. Due to the large forest areas, which are often difficult to access or characterized by insufficient infrastructure and severe climate conditions, frequent monitoring of the forest resources is a great challenge. Forest monitoring by the means of ground inventories is rather complicated or even impossible. The use of aerial photographs is also often insufficient and cost-intensive. As a result, forest information available today, often does not correspond to the current situation. This is true for wide parts of Siberia, for example. However, according to their own legislation and to fulfill international obligations up-to-date and reliable information on forest resources are essential. For instance, in order to update the Russian State Forest Account as well as for forest management and monitoring issues an annual update of forest information is obligatory. The use of EO-technologies offers an excellent tool to obtain spatial forest information. Especially for regions covered by vast forest areas the combined use of high and low resolution EO-data is the most promising and cost-efficient strategy. Therefore, this GSE-FM service option follows a two-level strategy: Level 1: Low and medium resolution satellite data are used for operational monitoring of forest changes over large areas caused by fires, cutting, and other natural and human induced disturbances. Territories where significant changes occurred are identified at this level. Level 2: Both high-resolution satellite data and aerial photos are used for a detailed inventory of all candidates registered by the first level observations. Ground truth data (inventory maps, topography, archive EO data etc.) are used in addition.

FP6-POLICIES, Safe Management of Mining Waste and Waste Facilities (SAFEMANMIN)

The project aims at supporting the implementation of the proposed Directive of the European Parliament and of the Council on the management of waste from the extractive industries 2003/0107. The Directive was prepared following several major accidents with a serious impact on the environment, and it has the purpose of ensuring a safer management of the mining waste facilities, so that such accidents will not occur in the future. This project addresses particularly Article 9, which provides for the classification of waste facilities with respect to the possible consequences of an accident, and respectively the Annex II: Characterisation of mining waste and Annex III: Criteria for the classification of waste facilities. The activities of the project are divided into four major work packages as follows: - Preparation of a Methodology for the Characterisation of Mining Waste - Elaboration of a Risk Assessment Methodology for the Classification of Mining Waste Facilities, including Old/Abandoned Mining Waste Facilities - Review of Techniques for the Prevention and Abatement of Pollution Generated by Mining Wastes - Development of a Decision Support Tool for Minimising the Impact of the Mining Industry on the Environment. The Consortium co-ordinated by BIUTEC, Austria, includes universities, research institutes, NGOs and implementing authorities from 8 European countries, both Members of the EU and accession countries. The experts team is highly qualified and has many years of experience and research in this area, so that the best outputs can be obtained. The project will build on the results of other projects carried out in this field, and will relate closely to on-going projects, so that there is no overlap in our activities. In order to provide an effective tool for the potential beneficiaries, the project team will consult with representatives of the stakeholders before the final versions of the outputs are publicly made available on the project web-site.

Biological Detoxification of Fumonisins

The overall aim of this project is to find microorganisms or specific enzymes which are able to degrade and detoxify fumonisins, a recently found class of mycotoxins. Such microorganisms or enzymes should then be used as part of a feed additive which manages the degradation of these toxins in the intestinal tract of animals during feed digestion. The major project phase is the screening for such fumonisin degrading microorganisms or enzymes. In first place these organisms should be newly isolated strains out of various habitats, but also strain collections are investigated as well as commercially available enzymes. Characterisation of newly found microorganisms via morphological, physiological and molecular biological methods represents another phase within this project. The third major project phase includes the development of appropriate analytical methods for analysis of samples from degradation experiments out of various different matrices. HPLC, ELISA and LC-MS methods are investigated. The characterisation of metabolites evolving during the microbial and/or enzymatic degradation of fumonisins is defined as a working package as well. In order to show the real detoxification of fumonisin B1 by the microorganisms (or enzymes) several different toxicity test-systems (cell-culture assays, bioassays)are under investigation.

Kohlenstoffspeicherung in einem ungenutzten Kalkbuchenwald des Nationalparks Hainich

Differenzierung der Quellen- und Senkenfunktion des Bodens unter Berücksichtigung der Nutzungsgeschichte. Im Rahmen des CARBOEUROFLUX-Projekts wurden im Hainich (Thüringen) Kohlenstoff (C)- Speicherungsraten festgestellt, die der Vorstellung der Kohlendioxid-Neutralität von alten Wäldern widersprechen und die Frage nach deren Kyoto-Relevanz aufwerfen. Im Rahmen europäischer Projekte lässt sich allerdings nicht klären, wie diese hohen Speicherraten entstehen und wo C im System verbleibt. Wir vermuten, dass durch historischen C-Export, z.B. infolge von Streunutzung, die Böden im Hainich verarmten und die entleerten Speicher jetzt wieder aufgefüllt werden. Um das Ausmaß des nutzungsbedingten C-Exports abschätzen zu können, werden aus Schriftquellen Art und Umfang der Biomassenutzung in ihrer zeitlichen und örtlichen Entwicklung rekonstruiert. Zudem untersuchen wir, welche Anteile des C-Eintrages veratmet, gespeichert und über den Wasserpfad exportiert werden. Hierzu werden 13C und 14C- Isotopenverhältnisse an Bodengasen sowie gelöstem und festem Boden- C bestimmt. Unsere Untersuchungen zielen auf ein grundlegendes Verständnis der C-Speicherung im Jahresverlauf ab. Die Zusammenarbeit mit dem Kompetenzzentrum 'Dynamik Komplexer Geosysteme' und dem europäischen CARBOEUROPE Cluster wird die Doppelerhebung von Daten verhindern und deren gegenseitige Verfügbarkeit sicherstellen. Ziel der Arbeit ist es, den historischen Kohlenstoffexport insbesondere unter Berücksichtigung der forstlichen Nebennutzung abzuschätzen. Hierzu soll anhand von Literaturdaten einerseits die Vegetationsgeschichte geklärt werden. Andererseits soll der im Untersuchungsgebiet im Zuge der forstlichen und landwirtschaftlichen Nutzungen erfolgte Biomasseentzug nach Art und Umfang dokumentiert werden. Diese Arbeiten sind notwendig, um den Einfluss der Nutzungsgeschichte auf die Kohlenstoffspeicherung im Untersuchungsstandort abzuschätzen. Im Rahmen des Gesamtprojektes sollen zunächst Daten zur Entwicklung der Biomasse im Untersuchungsgebiet zusammengestellt werden. Eine weitere Aufgabe besteht darin, auf der Basis von Literaturstudien einen möglichen Vergleichsstandort mit unterschiedlicher Nutzungsgeschichte zu identifizieren.

Schwerpunktprogramm (SPP) 1167: Quantitative Niederschlagsvorhersage, Coordination of the SPP 1167: Study of the process chain and predictability of precipitation by combining the D-PHASE ensemble and the COPS data sets in the COPS domain

In contrast to their advances in other areas, weather forecast models have not been successful in improving the Quantitative Precipitation Forecast during the last 16 years. One reason for this stagnation is the lack of comprehensive, high-quality data sets usable for model validation as well as for data assimilation, thus leading to improved initial fields in numerical models. Theoretical analyses have identified the requirements measured data have to meet in order to close the gaps in process understanding. In field campaigns, it has been shown that the newest generation of remote sensing systems has the potential to yield data sets of the required quality. It is therefore time to combine the most powerful remote sensing instruments with proven ground-based and airborne measurement techniques in an Intensive Observations Period (IOP). Its goal is to serve as a backbone for the SPP 1167 by producing the demanded data sets of unachieved accuracy and resolution. This requires a sophisticated scientific preparation and a careful coordination between the efforts of the institutions involved. For the first time, the pre-convective environment, the formation of clouds and the onset and development of precipitation as well as its intensity will be observed in four dimensions simultaneously in a region of sufficient size. This shall be achieved by combining the IOP with international programs and by collaboration between leading scientists in Europe, US and other countries. Thus, the IOP is a unique opportunity to make Germany the setting of an international field campaign featuring the newest generation of measurement systems such as scanning radar and lidar and leading to outstanding advances in atmospheric sciences.

FP6-SUSTDEV, Integrated Health, Social and Economic Impacts of Extreme Events: Evidence, Methods and Tools (MICRODIS)

Recent events such as the Pakistan earthquake, Hurricane Katrina, the Indian Ocean tsunami and the European heat waves of 2003 reveal the vulnerability of societies to extreme events. The goal of this project is to strengthen prevention, mitigation and preparedness strategies in order to reduce the health, social and economic impacts of extreme events on communities. The objectives of the MICRODIS project are to strengthen the scientific and empirical foundation on the relationship between extreme events and their impacts; to develop and integrate knowledge, concepts, methods and databases towards a common global approach and to improve human resources and coping capacity in Asia and Europe through training and knowledge sharing. This integrated project involves 19 partners from Asia and Europe, including research, policy and ground roots institutions. The outputs will include an evidence-base on impacts, field methodologies and tools for data compilation, impact models, and integrated vulnerability assessments. It will also strengthen standardised data collection of extreme events and their impacts at local, regional and global levels.

FP6-SUSTDEV, Sustainable Water management Improves Tomorrow's Cities'Health (SWITCH)

Context: With increasing global change pressures, and due to existing limitations, and un-sustainability factors and risks of conventional urban water management (UWM), cities experience difficulties in efficiently managing the ever scarcer water resources, their uses/services, and their after-use disposal, without creating environmental, social and/or economic damage. In order to meet these challenges, SWITCH calls for a paradigm shift in UWM. There is a need to convert adhoc actions (problem/incident driven) into a coherent and consolidated approach (sustainability driven). This calls for an IP Approach. Research conceptSWITCH therefore proposes an action research project which has as a main objective: The development, application and demonstration of a range of tested scientific, technological and socio-economic solutions and approaches that contribute to the achievement of sustainable and effective UWM schemes in 'The City of the future'.The project will be implemented by different combinations of consortium partners, along the lines of seven complementary and interactive themes. The research approach is innovative for the combination of: action research: address problems through innovation based upon involvement of users.learning alliances: to link up stakeholders to interact productively and to create win-win solutions along the water chain; multiple-way learning: European cities learn from each other and from developing countries, and vice versa.multiple-level or integrated approach: to consider the urban water system and its components (city level) in relation to its impacts on, and dependency of, the natural environment in the river basin (river basin level), and in relation to Global Change pressures (global level).Instruments and scopeAn IP with 30 partners, their resources, and a total budget of 25,191,396 EURO including budget for demonstration activities in 9 Cities in Europe and developing countries. Prime Contractor: UNESCO - Institute for Water Education, Delf, Netherlands.
