bifa wurde vom Bayerischen Staatsministerium für Umwelt und Gesundheit mit der Durchführung des Projekts IPP als Instrument des betrieblichen Klimaschutzes - eine Anleitung insbesondere für kleine und mittlere Unternehmen (KMU) beauftragt. Im Rahmen dieses Projekts werden u. a. acht Workshops mit Vertretern der Wirtschaft durchgeführt. Der erste Workshop fand bereits im Februar 2010 unter dem Motto Grüne Logistik: Visionen - Chancen - Risiken statt. Es nahmen 13 Unternehmer aus verschiedenen Bereichen der Logistik teil. Nach kurzen Impulsvorträgen zur Integrierten Produktpolitik und Grünen Logistik wurden in drei Arbeitsgruppen Möglichkeiten der Umsetzung von grüner Logistik im eigenen Unternehmen diskutiert und Ansatzpunkte gesucht, wie durch verstärkte Kooperation und Kommunikation die umweltbezogenen Vorteile der grünen gegenüber der normalen Logistik noch weiter ausgeschöpft werden können. Das äußerst heterogene Teilnehmerfeld wurde sehr positiv bewertet. So beschreibt ein Teilnehmer: Da waren ein Unternehmer mit eigenem Fuhrpark, ein kleiner mittelständischer Spediteur, ein großer mittelständischer Spediteur und ich aus der verladenden Wirtschaft. In der abschließenden Diskussion tauchte neben zahlreichen Ansatzpunkten zur Umsetzung immer wieder eine Frage auf: Was ist Green Logistics ? Wie können wir sie messen, was umfasst sie, wer nimmt daran teil und wer bezahlt sie? . Zur Abgrenzung der grünen gegenüber der normalen Logistik müssen Standards geschaffen werden, die den Unternehmen helfen, sich noch intensiver mit Möglichkeiten der Umweltentlastung im Bereich der Logistik auseinanderzusetzen. In einem weiterführenden Workshop im April 2010 setzten sich die Teilnehmer mit diesen Fragestellungen auseinander und erarbeiteten unter dem Titel Grüne Logistik: Standards generieren und umsetzen - aber wie? Vorschläge und Handlungsempfehlungen für die Praxis. Das IPP-Projekt ist für unterschiedliche Wirtschaftszweige von großem Interesse: So wurden weitere Workshops zu Themen wie Reach , Emissionen/ CDM , Bauwirtschaft und Recycling erfolgreich durchgeführt. Methoden: Analyse und Moderation sozialer Prozesse.
The formation of biogeochemical interfaces in soils is controlled, among other factors, by the type of particle surfaces present and the assemblage of organic matter and mineral particles. Therefore, the formation and maturation of interfaces is studied with artificial soils which are produced in long-term biogeochemical laboratory incubation experiments (3, 6, 12, 18 months. Clay minerals, iron oxides and charcoal are used as major model components controlling the formation of interfaces because they exhibit high surface area and microporosity. Soil interface characteristics have been analyzed by several groups involved in the priority program for formation of organo-mineral interfaces, sorptive and thermal interface properties, microbial community structure and function. Already after 6 months of incubation, the artificial soils exhibited different properties in relation to their composition. A unique dataset evolves on the development and the dynamics of interfaces in soil in the different projects contributing to this experiment. An integrated analysis based on a conceptual model and multivariate statistics will help to understand overall processes leading to the biogeochemical properties of interfaces in soil, that are the basis for their functions in ecosystems. Therefore, we propose to establish an integrative project for the evaluation of data obtained and for publication of synergistic work, which will bring the results to a higher level of understanding.
The majority of the worlds forests has undergone some form of management, such as clear-cut or thinning. This management has direct relevance for global climate: Studies estimate that forest management emissions add a third to those from deforestation, while enhanced productivity in managed forests increases the capacity of the terrestrial biosphere to act as a sink for carbon dioxide emissions. However, uncertainties in the assessment of these fluxes are large. Moreover, forests influence climate also by altering the energy and water balance of the land surface. In many regions of historical deforestation, such biogeophysical effects have substantially counteracted warming due to carbon dioxide emissions. However, the effect of management on biogeophysical effects is largely unknown beyond local case studies. While the effects of climate on forest productivity is well established in forestry models, the effects of forest management on climate is less understood. Closing this feedback cycle is crucial to understand the driving forces behind past climate changes to be able to predict future climate responses and thus the required effort to adapt to it or avert it. To investigate the role of forest management in the climate system I propose to integrate a forest management module into a comprehensive Earth system model. The resulting model will be able to simultaneously address both directions of the interactions between climate and the managed land surface. My proposed work includes model development and implementation for key forest management processes, determining the growth and stock of living biomass, soil carbon cycle, and biophysical land surface properties. With this unique tool I will be able to improve estimates of terrestrial carbon source and sink terms and to assess the susceptibility of past and future climate to combined carbon cycle and biophysical effects of forest management. Furthermore, representing feedbacks between forest management and climate in a global climate model could advance efforts to combat climate change. Changes in forest management are inevitable to adapt to future climate change. In this process, is it possible to identify win-win strategies for which local management changes do not only help adaptation, but at the same time mitigate global warming by presenting favorable effects on climate? The proposed work opens a range of long-term research paths, with the aim of strengthening the climate perspective in the economic considerations of forest management and helping to improve local decisionmaking with respect to adaptation and mitigation.
The final goal of the EUROWET project is to integrate the substantial multidisciplinary European research in wetlands to help attain the sustainable management of the water cycle. This will be achieved by the translation of state-of-the art science developed at both national and European levels, into practical guidance for end-users. This will be achieved by a comprehensive review, expert assessment and a focussed dissemination strategy. There is considerable scientific knowledge and technical experience gained in diverse aspects of wetland science and management including hydrology, biogeochemistry, ecology restoration, socio-economic and policy analysis. However the results of research and management experience are still too fragmentary and not sufficiently orientated to problem-solving or simply inadequately framed to be effectively transferred to, or used by, stakeholders and policy-makers. Simultaneously the general outcome of the scientific research has been increased awareness of the significance of wetlands in delivering goods and services important for human welfare including quality of life, biodiversity conservation and maintenance or enhancement of environment quality. Despite this wetlands continue to be degraded and lost throughout Europe without adequate consideration of the wider benefits to be achieved from this management. The new Water Framework Directive (WFD) promotes a unique opportunity to redress this problem by means of the holistic, integrated approach to water management. There is currently in preparation horizontal guidance on Wetlands as part of the Common Implementation Strategy (CIS) process. There is however work still to be done on providing more specific scientific and technical guidance on the effective implementation of the Directive with respect to wetlands. This is particularly the case in relation to Integrated River Management, the CIS cluster within which wetlands are being considered in the WFD.
Pflanzen im Allgemeinen und Bäume im Speziellen reagieren sehr sensibel auf klimatische Veränderungen. Der Kohlenstoff- und Wasserhaushalt wird unter Feldbedingungen gemessen und gibt so Aufschluss über physiologische Regelmechanismen (z.B. zwischen Wasserhaushalt und dem Öffnungsgrad der Stomata) oder das Baumwachstum. Mit Hilfe von systemischen Modellen interpretieren wir die ökophysiologischen Messungen und folgern daraus, wie weit sich einzelne Baumarten an veränderte klimatische Bedingungen anpassen können und ab wann artspezifische physiologische Grenzen erreicht werden. Im Wallis wachsen Waldföhren und Flaumeichen zumindest zeitweise am Rande ihrer physiologischen Möglichkeiten. Erste Resultate zeigen, warum die Flaumeiche (Quercus pubescens) unter den herrschenden klimatischen Bedingungen physiologische Vorteile gegenüber der Waldföhre (Pinus sylvestris) hat.

Existing models of soil organic matter (SOM) formation consider plant material as the main source of SOM. Recent results from nuclear magnetic resonance analyses of SOM and from own incubation studies, however, show that microbial residues also contribute to a large extent to SOM formation. Scanning electron microscopy showed that the soil mineral sur-faces are covered by numerous small patchy fragments (100 - 500 nm) deriving from microbial cell wall residues. We will study the formation and fate of these patchy fragments as continuously produced interfaces in artificial soil systems (quartz, montmorillonite, iron oxides, bacteria and carbon sources). We will quantify the relative contributions of different types of soil organisms to patchy fragment formation and elucidate the effect of redox con-ditions and iron mineralogy on the formation and turnover of patchy fragments. The develop-ment of patchy fragments during pedogenesis will be followed by studying soil samples from a chronosequence in the forefield of the retreating Damma glacier. We will characterize chemical and physical properties of the patchy fragments by nanothermal analysis and microscale condensation experiments in an environmental scanning electron microscope. The results will help understanding the processes at and characteristics of biogeochemical interfaces.
Fusarium species of the Gibberella fujikuroi species complex cause serious diseases on different crops such as rice, wheat and maize. An important group of plant pathogens is the Gibberella fujikuroi species complex (GFC) of closely related Fusarium species which are associated with specific hosts; F. verticillioides and F. proliferatum are particularly associated with maize where they can cause serious ear-, root-, and stalk rot diseases. Two other closely related species of the GFC, F. mangiferae and F. fujikuroi, which share about 90Prozent sequence identity with F. verticillioides, are pathogens on mango and rice, respectively. All of these species produce a broad spectrum of secondary metabolites such as phytohormones (gibberellins, auxins, and cytokinins), and harmful mycotoxins, such as fumonisin, fusarin C, or fusaric acid in large quantities. However, the spectrum of those mycotoxins might differ between closely related species suggesting that secondary metabolites might be determinants for host specificity. In this project, we will study the potential impact of secondary metabolites (i.e. phytohormones and certain mycotoxins) and some other species-specific factors (e.g. species-specific transcription factors) on host specificity. The recently sequenced genomes of F. mangiferae and F. fujikuroi by our groups and the planned sequencing of F. proliferatum will help to identify such determinants by genetic manipulation of the appropriate metabolic pathway(s).
