Die Europäische Kommission wird voraussichtlich eine Folgenabschätzung sowie einen Gesetzesentwurf zur indirekten Landnutzungsänderung (ILUC) in Zusammenhang mit der Biokraftstoffproduktion veröffentlichen. Die Einführung einer EU-Richtlinie zur indirekten Landnutzungsänderung in der Richtlinie für Erneuerbare Energien (RED) und der Richtlinie zur Kraftstoffqualität (FQD), hat möglicherweise Einfluss auf derzeitige Investitionen und Arbeitsplätze in der europäischen Biokraftstoffindustrie. Im Auftrag der Umweltorganisation Transport & Environment hat Ecofys untersucht, inwieweit der Biokraftstoffsektor unter dem Gesichtspunkt der Bestandswahrung gegen die Einführung einer ILUC-Richtlinie auf EU-Ebene geschützt werden kann. Dies wird mit dem Begriff 'Grandfathering' beschrieben. Der Bericht beginnt mit einem Überblick über den EU Biokraftstoffmarkt und -sektor. Er analysiert die verschiedenen Auswirkungen möglicher ILUC Maßnahmen in Hinblick auf den Sektor und geht der Frage nach, inwieweit gegenwärtige Investitionen und Arbeitsplätze geschützt werden müssen. In einem zweiten Schritt untersucht der Bericht die Grandfathering Klausel, die aktuell in der RED und FQD Richtlinie enthalten ist, sowie weitere mögliche Grandfathering Optionen. Die Studie kommt zu dem Schluss, dass die Einführung einer ILUC Politikmaßnahme bei gleichzeitigem Erhalt der Arbeitsplätze und der Investitionen in Biokrafstoffproduktion möglich ist, wenn das Biokraftstoffverbrauchsniveau von 2010-2012 bis zum Jahr 2020 von der ILUC Richtlinie ausgenommen wird. Dies würde bedeuten, dass eine mögliche ILUC Richtlinie sich lediglich auf die zukünftige Biokraftsoffproduktion ab 2020 bezieht. Die ILUC-Maßnahme würde den gesamten Biokraftstoffverbrauch in der EU nicht deutlich verringern, da die Ziele der RED und FQD für 2020 unverändert bleiben. Dennoch könnten auf den EU Biodieselsektor Herausforderungen zukommen, wenn z. B. neue ILUC-Faktoren eingeführt oder der Mindestschwellenwert für Treibhausgasausstoß angehoben würde. Ein Grandfathering des derzeitigen Biokraftstoffverbrauchs würde dem entgegenwirken und heutige Investitionen und Arbeitsplätze sichern. Die Ergebnisse der Studie wurden am 22. März 2012 dem Europäischen Parlament vorgestellt.
Durum wheat is mainly grown as a summer crop. An introduction of a winter form failed until now due to the difficulty to combine winter hardiness with required process quality. Winter hardiness is a complex trait, but in most regions the frost tolerance is decisive. Thereby a major QTL, which was found in T. monococcum, T.aestivum, H. vulgare and S.cereale on chromosome 5, seems especially important. With genotyping by sequencing it is now possible to make association mapping based on very high dense marker maps, which delivers new possibilities to detect main and epistatic effects. Furthermore, new sequencing techniques allow candidate gene based association mapping. The main aim of the project is to unravel the genetic architecture of frost tolerance and quality traits in durum. Thereby, the objectives are to (1) determine the genetic variance, heritability and correlations among frost tolerance and quality traits, (2) examine linkage disequilibrium and population structure, (3) investigate sequence polymorphism at candidate genes for frost tolerance, and (4) perform candidate gene based and genome wide association mapping.
The project aims to theorize the scalar organization of natural resource governance in the European Union. This research agenda is inspired by critical geographers' work on the politics of scale. The research will examine an analytical framework derived from theories of institutional change and multi-level govern-ance to fill this theoretical gap. Furthermore, it will review conceptualizations of the state in institutional economics, evaluate their adequacy to capture the role of the state in the dynamics identified, and develop them further. The described processes may imply shifts in administrative levels, shifts in relations between different levels and changes in spatial delimitations of competent jurisdictions that result, for example, from decentralization or the introduction of river basin oriented administrative structures. The research investigates the implications of two European Directives: the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). They both have potentially great significance for the organization of marine and water governance at the level of Member States and below, and adhere to similar regulatory ideas for achieving good ecological status of waters. A multiple case study on changes in the scalar reorganization of marine and water governance that result from the implementation of the Directives will be carried out. It will rely on qualitative and quantitative data gathering based on semi-structured interviews and review of secondary and tertiary sources looking at Portugal, Spain, and Germany. It specifically addresses the role of social ecological transactions, the structure of decision making processes and the role of changes in contextual factors (such as ideologies, interdependent institutions and technology).
Mit zunehmend ländlicher Prägung des Raumes und dispersen Siedlungsstrukturen nimmt die Bündelungsfähigkeit der Nachfrage im Personenverkehr ab. Die Folgen sind auf der Nutzerseite ein lückenhaftes Mobilitätsangebot des öffentlichen Personennahverkehrs und eine starke Auto-Orientierung im individuellen Verkehrsverhalten. Für die Betreiberseite bedeutet die niedrige Nachfrage und geringe Bündelungsfähigkeit einen defizitären Betrieb ihrer Verkehre. Die in der Regel liniengebundenen Busangebote konzentrieren sich zumeist auf nachfragestarke, meist längere Distanzen betreffende Relationen und sind auf die Hauptverkehrszeiten und damit insbesondere auf den Arbeitspendler- und Schülerverkehr ausgerichtet. In den Schwachlastzeiten und im Kurzstreckenbereich nehmen die Verkehrsangebote hingegen deutlich ab. Ausgehend von dieser Problemlage wurde vom Bundesministerium für Bildung und Forschung (BMBF) das Forschungsvorhaben 'Personennahverkehr für die Region' initiiert, welches durch wissenschaftliche und praktische Erkenntnisse dazu beitragen soll, eine Erhöhung der Effizienz und Qualität im Personennahverkehr außerhalb der großen Ballungsräume zu erreichen. Das Vorhaben umfasst insgesamt zehn Projekte. Das Wuppertal Institut ist neben der Bearbeitung des Projektes IMAGO an der Entwicklung und Umsetzung des MultiBus-Konzeptes beteiligt. Das MultiBus-Projekt versucht, ein kunden- und bedarfsorientiertes öffentliches Verkehrssystem zu entwickeln, mit dem der ÖPNV im ländlichen Raum entscheidend gestärkt werden kann. Angestrebt wird die Realisierung eines modernen Rufbussystemes, das die wirksame und bedarfsgerechte Verdichtung von Mobilitätsangeboten im ländlichen Raum am Beispiel der drei Gemeinden Gangelt, Selfkant und Waldfeucht (Kreis Heinsberg) praktisch demonstriert. Mit einer flächendeckenden Bedienung, einem ausgeweiteten Angebotsspektrum, dem Einsatz von komfortablen Kleinbussen und der zielgerichteten Einbettung des MultiBus-Systems in bestehende regionale Verkehrsangebote soll veranschaulicht werden, dass regionale Aufgabenträger und Verkehrsbetriebe mit kundenorientierten Mobilitätsdiensten attraktive sowie wettbewerbsfähige Alternativen zur Verkehrsmittelnutzung bereitstellen können und zur schrittweisen Individualisierung des regionalen Personennahverkehrs befähigt sind. Innerhalb des MultiBus-Projektes werden ferner die Möglichkeiten einer Kopplung von Personenbeförderung und lokalen Kleinguttransporten untersucht. Mit dem MultiBus sollen die bislang von verschiedenen Dienstleistern unkoordiniert betriebenen Kleingutverkehre im Untersuchungsraum gebündelt werden, indem ein auf die Serviceanforderungen der Kurier-, Express-, Paketdienste abgestimmter Verteil- und Sammeldienst für Unternehmen und Haushalte aufgebaut wird.
Introduction: The United Nations Framework Convention on Climate Change classified SF6 as greenhouse gas, and the Annex I countries are obliged to publish the inventory of SF6 and to reduce emissions. However, survey data show an increasing concentration of SF6 (1), and recent evaluations demonstrate that only 30 Prozent of SF6 emissions are reported (2). Novel regulations and technical development must aim at decreasing SF6 emissions below the natural decomposition rate. For dielectric insulation applications, i.e. in situations where discharges are exceptional, it might be possible to replace SF6 by a different gas or gas mixture. No alternative gas is established, despite an extensive study of the dielectric strength of electron attaching gases in the past (3), (4). As many of the well investigated gases are covered by the Kyoto protocol, new options must be provided by fundamental research. In the present research project, the dielectric strength of alternative gases will be evaluated. There is general agreement, that mixtures of two or more gases are most suitable for replacing SF6 in dielectric insulation applications. Due to 'synergistic effects' the dielectric strength of a mixture can be higher than of pure gases (5), or at least the dielectric strength of a mixture can be higher than the linear combination of the strength of the constituents (6). Various types of synergistic effects have so far been described on the basis of the electron velocity distribution function or on the basis of ion-neutral collisions. Methods: The methods developed for investigating electron attaching gases may be classified to three groups: Phenomenological, macroscopic and microscopic methods. The research strategy of the project at hand is a combination of two established methods. In a Pulsed Townsend Discharge (PTD) experiment the macroscopic parameters of electron-ion swarms in attaching gases are measured. Synergistic effects in gas mixtures will be investigated microscopically by Monte Carlo (MC) simulations. The PTD is a traditional method and considerable experience has been gained at the HVL during the years 1980-1990 (7,8). The group of de Urquijo (Mexico) lately used a PTD for studying the alternative gas CF3I (9). In figure 1 the principle of the PTD setup is given. The swarm parameters are obtained from a fit of the analytical expression of the displacement current to the recorded current. Refer to (10) for more details on our swarm parameter experiment SParX. Recently satisfying agreement was achieved between MC simulations and data from PTD experiments (11, 12). The critical issue of these simulations is the availability of a consistent set of cross sections of electron-neutral and ion-neutral collisions. In the present study the output of SParX serves for calibrating the cross sections and the simulations. usw.
The fire blight disease caused by the bacterium Erwinia amylovora, is currently the major constraint for apple production in several European countries including Germany and Switzerland. In recent years several infections occurred which have led to costs in the tens of millions Euros. The antibiotic Streptomycin (Plantomycin®), which is the only effective plant protective agent, can only be applied under particular restrictions. Planting of fire blight resistant cultivars seems to be the most promising solution, which is environmental and producer friendly. Unfortunately, the available fire blight resistant apple cultivars are non-competitive on the market, because of their inferior fruit quality. The improvement of established cultivars like 'Golden Delicious' or 'Gala' using classical breeding strategies is impossible because apple is self-incompatible and heterozygous. Each offspring of a sexual cross between such a cultivar and a resistant genotype will be genetically different to each of the parents. Linkage drag coming from the resistant led often to a decrease in fruit quality. Several crosses with cultivars of good quality are necessary to remove most of the unwanted traits and the result will be a completely new cultivar. Breeding of such a new apple cultivar is time consuming and in the end it is not clear, whether the new cultivar will be accepted by consumers and growers or not. Under these premises, the introduction of a specific gene into a particular cultivar which already has all qualities necessary, except the trait in question, is attractive. The recombinant DNA-technology offers the most promising strategy to solve the problem of fire blight by using Malus own genes without the need to change the popular cultivars. The development of cisgenic plants seems to be a realistic and successful strategy. Cisgenic plants contain only genes, which originates from crossable species and not from outside of the primary genepool. They are therefore comparable to classical bred plants and expected to be acceptable by consumers and growers. The methodology to produce such a durable resistant cisgenic apple cultivar has already been established, but an apple fire blight resistance gene (or linked gene set) is still needed. Recently a strong Fieblight resistance has been identified on chromosome 3 of the apple hybrid Malus x robusta 5. This project focuses on the isolation of the gene(s) inducing the resistance of M. x robusta 5 and its cloning into the susceptible cultivar Gala. Furthermore the interaction of this (or these) genes products with gene products of the pathogen will be studied so to understand the interaction mechanisms and therefore evaluate the durability of the resistance.
Current agricultural practices have caused serious ecological problems that affect agricultural sustainability by reducing ecological functions and biodiversity. There is evidence that the density of natural enemies of crop pests is related to high biodiversity. This has been shown for landscape-scale management practices (augmenting landscape complexity) and for intercropping systems (augmenting biodiversity at a local scale). However, the relative importance of local and landscape management and the mechanisms through which biodiversity may enhance biological control are still unknown. In this project we will investigate how increased plant diversity at different spatial scales affects biological control of herbivores in potato fields in the Andes. By (1) increasing plant diversity at the field scale and (2) choosing fields along a gradient in landscape complexity, the single and combined effects of these variables on biological control will be analyzed. Furthermore, we will examine whether an increase in plant functional group diversity (trap plants, repellent plants and flowering plants) enhances biological control. The introduction of trap, repellent and flowering plant species to potato fields is expected to reduce the density of the potato moth (Phthorimaea operculella, Lepidoptera: Gelechiidae), a pest able to destroy 100Prozent of the potato crop. The role of constitutively emitted volatile organic compounds (VOCs), from selected weed species and potato, as signals for herbivores and their natural enemies in these interactions will be shown. The results of the project are expected to contribute to the development of sustainable and ecologically sound management methods for potato cultivation in the Andes. Therefore, the requirements and restrictions of management scales, local cropping practices and landscape management are considered.
The introduction of non-native species and its spread are recognized to be one of the major threats to biodiversity and ecosystem functioning. Climate change is expected to enhance ecosystem invasibility through changes in resource availability (e.g. water) and the risks of desertification in Mediterranean areas, however scientific studies are rare. This project will evaluate specific traits of a characteristic invader towards competition for limited resources and the consequent alteration of community functioning under decreasing ground water availability. We selected a protected Mediterranean costal dune system of high ecological value, where large-scale extraction of ground water provides excellent experimental conditions to study changes in the competitive balances among invasive and native species. We will analyse the effects i) at the seedling level to evaluate changes in plant establishment; ii) at the plant level to gain major insights on the spatial and temporal partitioning of water sources and regulating mechanisms of selected species and iii) at the community level to evaluate changes in water flow, competition and facilitation (e.g. hydraulic lift), community functioning, and changes in invasibility of the system. The aim is the identification of key processes controlling the competitive balances between invasive neophytes and native species and invasibility of semi-arid systems to contribute to a risk assessment under global change scenarios.
Objective: Hydrogen storage is a key enabling technology for the extensive use of H2 as energy carrier. In fact, one of the greatest technological barriers to the widespread introduction of hydrogen in vehicles is an efficient and safe storage method. Providing economically and environmentally attractive solutions for these three storage options for transport applications and reinforcing the competitiveness of the European car industry are indeed the main STORHY objectives. This IP is a European initiative on automobile H2 storage driven by major European car manufacturers and covering the full spectrum of currently qualified technologies. Although the primary target of STORHY is the automobile industry, the preparation of spin-offs for stationary systems is also considered. In the three vertical SPs, viable solutions will be developed based on the defined requirements. SP Pressure Vessel concentrates on developing a 700 bar storage technology including production technologies for composite vessels. SP Cryogenic Storage will develop free form lightweight tanks manufactured from composites as well as adequate production technologies. SP Solid Storage assesses current progress in the storage of solid materials and will focus its primary research activities on alienates. Furthermore, up scaling of the material production process will be considered resulting in the construction and testing of prototype tanks. These developments are accompanied by safety studies and pre-normative research within SP SAR. The three storage technologies will be evaluated applying technical, economic, social and environmental criteria in SP Evaluation. The final outcome of the project is to identify the most promising storage solution for different vehicle applications. Such results should illuminate the future perspectives of H2 storage for transport and stationary applications and assist decision makers and stakeholders on the road to an H2 economy.
