Das Projekt B1 'Allometrie und Raumbesetzung von krautigen und holzigen Pflanzen' ist Teil des Sonderforschungsbereiches 607 Wachstum und Parasitenabwehr und befindet sich bereits in der vierten Phase des seit 1998 laufenden Forschungsprojektes. Bisher wurde im Projekt B1 die Allometrie als Resultat der pflanzeninternen Steuerung der Allokation untersucht. Auf Individuenebene wurden Allometrie und ihre Veränderung für verschiedene Baumarten in verschiedenen ontogenetischen Stadien untersucht. Auf Bestandesebene wurden die self-thinning-Linien von Yoda und Reineke für krautige bzw. holzige Pflanzenbestände analysiert. Bisherige Allometriebestimmungen erbrachten für diese Arten zwar ähnliche Größenordnung aber auch charakteristische Unterschiede, die Ausdruck spezifischer Strategien der Raumbesetzung und -ausbeutung widerspiegeln. Die bisher vereinzelten Auswertungen sollen in Phase IV in eine übergreifende Analyse (versch. Arten, ontogenetische Stadien, Konkurrenzsituationen, Störfaktoren) der Allometrie auf Pflanzen- und Bestandesebene münden.
The project examines funding of environmental technology development and commercialisation. The objectives are to: measure the performance of existing funding schemes (emphasising commercial-type funding); determine how environmental aspects are dealt with; identify obstacles; and suggest evolution of new schemes. Eight project work packages address these objectives, and also include development of environmental technology typologies, analysis of funding gaps, and comparison to Japan and the USA. The project supports SSP 5A by connecting policy and practice, linking researchers from across the EU, and using wide consultation to disseminate knowledge and maximise exploitation of research results. Consortium partners are drawn from five EU states, and have expertise and networks in private and public environmental technology funding and technology development processes. Stakeholder consultation with private and public funders, developers, academics, policy makers and NGOs will support research and knowledge dissemination. Consultation will include major public conferences and forums, sector-specific focus groups, and workshops to test analysis and geographic variations. Consultation and publication and dissemination of the final report will spur innovation by private and public funders, supporting knowledge exploitation after project completion. Research will emphasise private sector solutions, but will also include public-private partnerships, which are innovative measures that can assist in closing the funding gap. The varying applicability of such partnerships across different EU states will also be considered. The two project deliverables will be a database containing research and contact information, and a widely published final report that will integrate all research and recommendations. Prime Contractor: Partenaires Europeens pour l'Environnement; Bruxelles; Belgium.
The aim of the current research is to identify regional sources and trans-boundary flow leading to the observed salinity of Lake Tiberias (LT) -also known as the Sea of Galilee or Lake Kinneret-, and its surroundings, which is considered the only natural surface fresh water reservoir of the area. The current study will include all sources of brines in the Tiberias Basin (TB) with specific emphasis of the relationship between the brines from the Ha'on and Tiberias Regions (HTR).The tasks will be achieved by a multidisciplinary approach involving: (i) numerical modelling of density-driven flow processes (i.e., coupled heat and dissolution of evaporites), (ii) hydrochemical studies, supplemented by investigations of subsurface structures.(i) Numerical modelling will be carried out by applying the commercial software FEFLOW® (WASY, GmbH) complemented with the open source code OpenGeoSys developed at the UFZ of Leipzig (Wang et al., 2009). The final goal is to build a 3D regional-scale model of density-driven flow that will result in: (1) revealing the different interactions between fresh groundwater and natural salinity sources (2) elucidate the driving mechanisms of natural brines and brackish water body's movements.(ii) Hydrochemical study will include major, minor and, if possible, rare earth elements (REE) as well as isotope studies. The samples will be analysed at the FU Berlin and UFZ Halle laboratories. Geochemical data interpretation and inverse modelling will be supported by PHREEQC. Hydrochemical field investigations will be carried out in Tiberias basin and its enclosing heights, i.e. the Golan, Eastern Galilee and northern Ajloun in order to search for indications of the presence of deep, relic saline groundwater infested by the inferred Ha'on mother-brine. The current approaches will be supplemented by seismic and statistical data analysis as well as GIS software applications for the definition of the subsurface structures. The key research challenges are: building a 3D structural model of selected regions of TB, adapting both structural and hydrochemical data to the numerical requirements of the model; calibrating the 3D regional-scale model with observational data. The results of this work are expected to establish suitable water-management strategies for the exploitation of freshwater from the lake and from the adjacent aquifers while reducing salinization processes induced by both local and regional brines.
The proposed RTN adopts a unified approach to a unique sainfoin (Onobrychis viciifolia) collection. It will provide excellent training for young researchers in evaluating traditional resources and developing novel strategies for sustainable agriculture. This is timely because of the pending CAP reforms. The RTN will offer multisectorial and multidisciplinary training at 12 first-class research institutions and 3 SMEs in 11 countries. It is based on a structured combination of research and training activities to ensure that the young researchers will achieve optimal development of professional skills for their future careers . The young researchers will greatly benefit from the vast expertise in a wide range of disciplines amongst the partners: agronomy, plant breeding, seed production and marketing, animal nutrition, veterinary science, chemical analysis, biochemistry, genetics and molecular biology. The scientific approach will develop a scientific and technical basis for animal feeding systems based on lower chemical inputs by re-popularising traditional fodder legumes for more efficient, animal- and environment-friendly farming systems. Sainfoin will be a showcase for an excellent fodder legume, which was widely grown in Europe before the use of commercial fertilisers and synthetic drugs. Currently, a considerable amount of research occurs on sainfoin but includes only a few cultivars. This prevents exploitation of its full genetic potential. The unique collection already available within this network and a concerted evaluation will lay the foundation for exploiting the full potential of this traditional forage crop in contemporary cultivation systems. Training will consist of extensive scientific education on a local and network-wide basis and include complementary skills, e.g. foreign languages, personal, social and inter-cultural skills (management skills and soft skills).

Objective: Changes in climatic conditions, land use practices and soil and sediment pollution have large-scale adverse impacts on water quantity and quality. The current knowledge base in river basin management is not adequate to deal with these impacts. Austere is both integrating and developing knowledge to resolve this and disseminating it to stakeholders. In the water cycle, soil is a key element affecting groundwater recharge and the chemical composition of both subsurface and surface waters (the latter is additionally affected by sediments). The proper functioning of the river-sediment-soil-groundwater system is linked to key biogeochemical processes determining the filter, buffer and transformation capacity of soils and sediments. Austere aims at a better understanding of the system as a whole by identifying relevant processes, quantifying the associated parameters and developing numerical models of the groundwater-soil-sediment-river system to identify adverse trends in soil functioning, water quantity and quality. The modelling addresses all relevant scales starting from micro-scale water/solid interactions, the transport of dissolved species, pollutants as well as suspended matter in soil and groundwater systems at the catchments scale, and finally the regional scale, with case studies located in major river basins in Europe. With this integrated modelling system, Austere provides the basis for improved river basin management, enhanced soil and groundwater monitoring programs and the early identification and forecasting of impacts on water quantity and quality during this century. Austere is committed to the dissemination and exploitation of project results through structured workshops, dedicated short courses, and the active participation of consortium partners in national and international conferences. A peer review panel supervises the quality and direction of the project.
The project SWERA will provide solar and wind resource data and geographic information assessment tools to public and private sector executives who are involved in energy market development. It will demonstrate the use of these instruments in investment and policy decision making and build local capacities for their continuous use. The project will enable private investors and public policy makers to assess the technical, economic and environmental potential for large-scale investments in technologies that enable the exploitation of two increasingly important sources of renewable energy. During this pilot project, tools for analysis and use of resource information will be developed, a global archive and review mechanism will be initiated, regional/national solar and wind resource maps generated and national assessment demonstrations performed. The overall goal is to promote the integration of wind and solar alternatives in national and regional energy planning and sector restructuring as well as related policy making. The project will enable informed decision making and enhance the ability of participating governments to attract increased investor interest in renewable energy. Thirteen countries will be directly involved in the pilot stage of the project. Global and regional maps will be available to all developing countries. The German Aerospace Center (DLR) will provide high resolution solar maps of the Direct Normal Irradiation. This is particularly important for concentrating solar power collectors. DLR will work with SUNY and INPE/LABSOLAR to integrate their high-resolution horizontal total radiation model. DLR and TERI will jointly execute the South Asian mapping using INSAT and METEOSAT-5 data. DLR will provide advice to national executing agencies and stakeholders on their activities and assist in the comparison of measurements and different mapping models.
GLORIA combines a Michelson interferometer with a detector array of 128 x 128 pixels and will be the first 2D infrared limb imaging spectrometer worldwide. It is designed for HALO and will measure the distribution of temperature and a considerable number of trace constituents along with cloud mapping with unprecedented spatial resolution in the free troposphere and lower stratosphere. It is an essential contribution to the HALO demo missions TACTS, POLSTRACC, and CIRRUS-RS. Imaging Fourier transform spectrometers impose a number of challenges with respect to instrument calibration / characterisation and for algorithm development. The work of the first proposal focused on characterisation and modeling of the instrument and on the development of methods and algorithms which are capable of generating calibrated spectra with high accuracy. Accurately calibrated spectra are a prerequisite for the retrieval of atmospheric parameters and the scientific data exploitation. Within this renewal proposal the developed characterisation methods will be applied to the instrument in flight configuration, and the new algorithms will be used to generate highly accurate calibrated spectra from the raw interferograms measured during the HALO demo missions. The work will be completed by a thorough error analysis for the calibrated spectra. Finally, instrument settings, calibration scenario and data processing shall be optimised with respect to data quality. This proposal contributes to the development of high technology sensors and instruments for the use on HALO.
This project aims at investigating a scientific and societal pressing subject which requires urgent attention: the geo-hazards associated with the imminent use of the Arctic Ocean under the changing conditions forced by Global Change. Due to the increasing temperatures, the Arctic region is experiencing a decline of glaciers and sea-ice. Sea-ice reduction will soon expose to exploration yet unknown seafloor and sub-seafloor geology. Given todays interest in natural resources exploitation, the Arctic regions will experience an increase in seafloor and sub-seafloor use and an accelerated development of infrastructures, especially in coastal and continental margin areas. The glacial environment of the Arctic land masses causes that physical processes along continental margins differ substantially from those at lower latitudes, where continental slopes are built with river-fed sediments and glacial influence is comparatively unimportant. Continental margins at lower latitudes are better studied because industrialized nations have previously focused their activities there. The response of the Arctic seafloor and sub-seafloor system to upcoming changes in physical oceanography and glacial conditions, and the resultant sedimentary processes are yet not understood. To evaluate the future response of the Arctic geological system to Global Change is necessary to further understand the interplay among past climate change, continental margin geology, and submarine slope stability. This project aims at filling that critical gap in understanding. The overarching goal of this project is to evaluate how the increase of temperature, within the bounds of current predictions, may change the behavior of the Arctic geological system and alter slope stability. To achieve the goal we will estimate the volume and rate of gas release into the atmosphere that might affect climate, and evaluate the potential feed back of climate change to gas-hydrate dissociation. We will analyze potential future scenarios of slope in-stability in the context of the combined effect of the removal of past ice loading, ongoing temperature change, and stability of the geological elements of the continental margin system.
MAGICPAH aims to explore, understand and exploit the catalytic activities of microbial communities involved in the degradation of persistent PAHs. It will integrate (meta-) genomic studies with in-situ activity assessment based on stable isotope probing particularly in complex matrices of different terrestrial and marine environments. PAH degradation under various conditions of bioavailability will be assessed as to improve rational exploitation of the catalytic properties of bacteria for the treatment and prevention of PAH pollution. We will generate a knowledge base not only on the microbial catabolome for biodegradation of PAHs in various impacted environmental settings based on genome gazing, retrieval and characterization of specific enzymes but also on systems related bioavailability of contaminant mixtures. MAGICPAH takes into account the tremendous undiscovered metagenomic resources by the direct retrieval from genome/metagenome libraries and consequent characterization of enzymes through activity screens. These screens will include a highend functional small-molecule fluorescence screening platform and will allow us to directly access novel metabolic reactions followed by their rational exploitation for biocatalysis and the re-construction of biodegradation networks. Results from (meta-) genomic approaches will be correlated with microbial in situ activity assessments, specifically dedicated to identifying key players and key reactions involved in anaerobic PAH metabolism.

In spite of a variety of efforts, tropical forests are still threatened by exploitation and conversion to agricultural land-use. Besides legal protection, sustainable management concepts are essential for stable conservation of these ecosystems. This project aims at identifying and optimizing the potentials for forest management for three different ecosystems (Dry Forest, Tropical Mountain Rain Forest, Paramo) along a height- and climate gradient in Southern Ecuador. Therefore, multiple and locally differentiated aspects of forest management have to be considered: the direct provision of goods (timber and non-timber forest products) as well as ecosystem services (carbon sequestration, water regulation), which are of increasing importance; moreover, the effects of forest management on biodiversity and the impacts of climate change on resilience indicators and the potential distribution of selected species with high potential for sustainable management or conservation should be investigated. First of all, the most important forest structure types and possible improvements of management alternatives have to be identified at the three sites for the assessment of different management concepts. The alternatives will be tested on experimental field plots and consequently monitored for their impacts on the locally most important criteria of forest management. A sound decision support tool will be developed, taking into account uncertainties with regard to input parameters and the relevance of different criteria of forest management. Therefore, Multi Criteria Decision Analysis will be used to generate locally adapted management concepts for the different ecosystems. Those concepts should be able to consider the multiple functions of forest management and will represent the forestry component in sustainable land-use models. The comprehensive studies will be carried out in close cooperation with other scientific teams from Germany and Ecuador as well as local institutions of relevance for forest management. The direct involvement of Ecuadorian students and young academics and the integration of the investigations in educational concepts will contribute to capacity building and local efforts for the enhancement of environmental competencies. Moreover, the experimental field plots will serve in parts as demonstration objects for the implementation of sustainable forest management concepts.
