This subproject aims to analyze the fragmentation of forest policy at both an international and national level for the selected countries, employing a discourse analysis approach. It is split into two sub-subprojects (SSPs). 'SSPa' conducts an analysis of discursive genealogies of forest policy in Germany, Sweden, and the US. 'SSPb' investigates the history of forest related discourses in three global environmental policy processes (UNFF, CBD, and UNFCCC). In doing so, both SSPs follow a three step procedure: In the first work package, relevant literature is reviewed and a theoretical and analytical framework is developed. In the second work package, empirical data (mostly formal and informal policy documents) are gathered and analyzed. In the third work package, emphasis is placed on the role of political 'elites' in the creation of fragmented forest policy discourses at different levels; in-depth interviews with policy stakeholders and experts add another perspective to the analysis in this work package. The project is expected to develop a new understanding not only of the fragmentation of multi-level and multi-sector forest policy discourses, but also of the way in which 'discourse elites' interact with and within these discourses. The results of the work packages will be published in peer reviewed journals and discussed with policy stakeholders and scientists in conferences and workshops.
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).
Barley (Hordeum vulgare) is an important cereal grain which serves as major animal fodder crop as well as basis for malt beverages or staple food. Currently barley is ranked fourth in terms of quantity of cereal crops produced worldwide. In times of a constantly growing world population in conjunction with an unforeseeable climate change and groundwater depletion, the accumulation of knowledge concerning cereal growth and rate of yield gain is important. The Nordic Genetic Resource Center holds a major collection of barley mutants produced by irradiation or chemical treatment. One phenotypic group of barley varieties are dwarf mutants (erectoides, brachytic, semidwarf, uzu). They are characterized by a compact spike and high rate of yield while the straw is short and stiff, enhancing the lodging resistance of the plant. Obviously they are of applied interest, but they are also of scientific interest as virtually nothing is known about the genes behind the development of plant dwarfism. The aim of this project is to identify and isolate the genes carrying the mutations by using state of the art techniques for gene cloning at the Carlsberg Laboratory. The identified genes will be connected with the mutant phenotype to reveal the gene function in general. One or two genes will be overexpressed and the resulting recombinant proteins will be biochemically and structurally characterized. The insights how the mutation effects the protein will display the protein function in particular. Identified genes and their mutant alleles will be tested in the barley breeding program of the Carlsberg brewery.
Biogeochemical interfaces shape microbial community function in soil. On the other hand microbial communities influence the properties of biogeochemical interfaces. Despite the importance of this interplay, basic understanding of the role of biogeochemical interfaces for microbial performance is still missing. We postulate that biogeochemical interfaces in soil are important for the formation of functional consortia of microorganisms, which are able to shape their own microenvironment and therefore influence the properties of interfaces in soil. Furthermore biogeochemical interfaces act as genetic memory of soils, as they can store DNA from dead microbes and protect it from degradation. We propose that for the formation of functional biogeochemical interfaces microbial dispersal (e.g. along fungal networks) in response to quality and quantity of bioavailable carbon and/or water availability plays a major role, as the development of functional guilds of microbes requires energy and depends on the redox state of the habitat.To address these questions, hexadecane degradation will be studied in differently developed artificial and natural soils. To answer the question on the role of carbon quantity and quality, experiments will be performed with and without litter material at different water contents of the soil. Experiments will be performed with intact soil columns as well as soil samples where the developed interface structure has been artificially destroyed. Molecular analysis of hexadecane degrading microbial communties will be done in vitro as well as in situ. The corresponding toolbox has been successfully developed in the first phase of the priority program including methods for genome, transcriptome and proteome analysis.
Previous studies indicated that the development and biogeochemistry of paddy soils relates to the parent material, thus the original soil paddies derive from. The proposed research focuses on redox-mediated changes in mineral composition and mineral-associated organic matter (OM) during paddy transformation of different soils. We plan to subject soil samples to a series of redox cycles, in order to mimic paddy soil formation and development. Soils with strongly different properties and mineral composition as well as at different states of paddy transformation; ranging from unchanged soils to fully developed paddy soils, are to be included. We hypothesize that dissolved organic matter is one key driver in redox-mediated transformations, serving as an electron donator as well as interacting with dissolved metals and minerals. The extent of effects shall depend on the parent soil's original mineral assemblage and organic matter and their mutual interactions. The experimental paddy soil transformation will tracked by analyses of soil solutions, of the (re-)distribution of carbon (by addition of 13C-labelled rice straw), of indicative biomolecules (sugars, amino sugars, fatty acids, lignin) and of minerals (including the redox state of Fe). For analyses of organic matter as well as of mineral characteristics we plan to utilize EXAFS and XPS, for Fe-bearing minerals also Mößbauer spectroscopy. This approach of experimental pedology seems appropriate to give insight into the major factors during paddy soil formation and development.
BACKGROUND: The Kingdom of Jordan belongs to the ten water scarcest countries in the world, and climate change is likely to increase the frequency of future droughts. Jordan is considered among the 10 most water impoverished countries in the world, with per capita water availability estimated at 170 m per annum, compared to an average of 1,000 m per annum in other countries. Jordan Government has taken the strategic decision to develop a conveyor system including a 325 km pipe to pump 100 million cubic meters per year of potable water from Disi-Mudawwara close to the Saudi Border in the south, to the Greater Amman area in the north. The construction of the water pipeline has started end of 2009 and shall be finished in 2013. Later on, the pipeline could serve as a major part of a national water carrier in order to convey desalinated water from the Red Sea to the economically most important central region of the country. The conveyor project will not only significantly increase water supplies to the capital, but also provide for the re-allocation of current supplies to other governorates, and for the conservation of aquifers. In the context of the Disi project that is co-funded by EIB two Environmental and Social Management Plans have been prepared: one for the private project partners and one for the Jordan Government. The latter includes the Governments obligation to re-balance water allocations to irrigation and to gradually restore the protected wetlands of Azraq (Ramsar site) east of Amman that has been depleted due to over-abstraction by re-directing discharge of highland aquifers after the Disi pipeline becomes operational. The Water Strategy recognizes that groundwater extraction for irrigation is beyond acceptable limits. Since the source is finite and priority should be given to human consumption it proposes to tackle the demand for irrigation through tariff adjustments, improved irrigation technology and disincentive to water intensive crops. The Disi aquifer is currently used for irrigation by farms producing all kinds of fruits and vegetables on a large scale and exporting most of their products to the Saudi and European markets and it is almost a third of Jordan's total consumption. The licenses for that commercial irrigation were finished by 2011/12. Whilst the licenses will be not renewed the difficulty will be the enforcement and satellite based information become an important supporting tool for monitoring. OUTLOOK: The ESA funded project Water management had the objective to support the South-North conveyor project and the activities of EIB together with the MWI in Jordan to ensure the supply of water for the increasing demand. EO Information provides a baseline for land cover and elevation and support the monitoring of further stages. usw.
The vegetation of East and South African savannahs has been shaped by the complex interaction of geo-biophysical processes and human impact. For both regions a controversial discussion is pertinent, as to whether massive degradation threatens the sustainability of livelihoods in these regions. Rangeland vegetation is mainly affected by environmental conditions (soil and climate) and by livestock management. Extent and interaction of these drivers are not well understood but have profound impacts on the resilience and vulnerability of these systems to be shifted toward unfavourable degraded or bush encroached states. The project aims to analyse and model rangeland vegetation in response to range management including livestock, soil quality and climatic conditions and to assess the impacts of changes in these conditions on the resilience and vulnerability of rangeland systems. Field measurements, remote sensing of vegetation patterns and dynamics and simulation modelling will be used to understand the dynamics of rangeland vegetation. We will use the 'fast' or 'state' variables potential of pastures to produce palatable biomass, the variability of this production, and the system's potential to recover from disturbance impact as indicators of resilience. 'slow' variables that control (or drive) the 'fast' variables such as management, climate and soil variables are recorded in cooperation with other subprojects as with A1 for soil variables. Results of the project will show which management activities are most favourable for individual regions to sustain plant production in the long term.
We will compare the role of an RNA-binding protein in floral transition in Arabidopsis thaliana and Hordeum vulgare. The RNA-binding protein AtGRP7 promotes floral transition mainly by downregulating the floral repressor FLC via the autonomous pathway. Based on our observation that AtGRP7 affects the steady-state abundance of a suite of microRNA precursors, we will globally compare the small RNA component of the transcriptome during FTi regulation in wild type plants and AtGRP7 overexpressors by deep sequencing. This will extend the knowledge on small RNAs associated with floral transition and provide insights into the regulatory network downstream of this RNA-binding protein. Further, we will address the question how AtGRP7 orthologues function in crop species lacking FLC homologues. A barley line with highly elevated levels of the AtGRP7 orthologue HvGR-RBP1 shows accelerated FTi and preanthesis development when compared to a near-isogenic parent with very low expression of this gene. We will characterize in detail flowering of this line with respect to different photoperiods and its vernalization requirement. We will employ a TILLING approach to further delineate the function of HvGR-RBP1 in flowering. A candidate gene approach to identify downstream targets will provide insights into the signaling pathways through which HvGR-RBP1 influences FTi. This project contributes to the development of a functional cross-species network of FTi regulators, the major strategic aim of the SPP.
Arsenic-contaminated ground- and drinking water is a global environmental problem with about 1-2Prozent of the world's population being affected. The upper drinking water limit for arsenic (10 Micro g/l) recommended by the WHO is often exceeded, even in industrial nations in Europe and the USA. Chronic intake of arsenic causes severe health problems like skin diseases (e.g. blackfoot disease) and cancer. In addition to drinking water, seafood and rice are the main reservoirs for arsenic uptake. Arsenic is oftentimes of geogenic origin and in the environment it is mainly bound to iron(III) minerals. Iron(III)-reducing bacteria are able to dissolve these iron minerals and therefore release the arsenic to the environment. In turn, iron(II)-oxidizing bacteria have the potential to co-precipitate or sorb arsenic during iron(II)- oxidation at neutral pH followed by iron(III) mineral precipitation. This process may reduce arsenic concentrations in the environment drastically, lowering the potential risk for humans dramatically.The main goal of this study therefore is to quantify, identify and isolate anaerobic and aerobic Fe(II)-oxidizing microorganisms in arsenic-containing paddy soil. The co-precipitation and thus removal of arsenic by iron mineral producing bacteria will be determined in batch and microcosm experiments. Finally the influence of rhizosphere redox status on microbial Fe oxidation and arsenic uptake into rice plants will be evaluated in microcosm experiments. The long-term goal of this research is to better understand arsenic-co-precipitation and thus arsenic-immobilization by iron(II)-oxidizing bacteria in rice paddy soil. Potentially these results can lead to an improvement of living conditions in affected countries, e.g. in China or Bangladesh.
