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.
Soil structure determines a large part of the spatial heterogeneity in water storage and fluxes from the plot to the hillslope scale. In recent decades important progress in hydrological research has been achieved by including soil structure in hydrological models. One of the main problems herein remains the difficulty of measuring soil structure and quantifying its influence on hydrological processes. As soil structure is very often of biogenic origin (macropores), the main objective of this project is to use the influence of bioactivity and resulting soil structures to describe and support modelling of hydrological processes at different scales. Therefore, local scale bioactivity will be linked to local infiltration patterns under varying catchment conditions. At hillslope scale, the spatial distribution of bioactivity patterns will be linked to connectivity of subsurface structures to explain subsurface stormflow generation. Then we will apply species distribution modelling of key organisms in order to extrapolate the gained knowledge to the catchment scale. As on one hand, bioactivity influences the hydrological processes, but on the other hand the species distribution also depends on soil moisture contents, including the feedbacks between bioactivity and soil hydrology is pivotal for getting reliable predictions of catchment scale hydrological behavior under land use change and climate change.
Sandy soils of the arid/semiarid dune fields of the Palestinian Gaza Strip and the Israeli western Negev are extensively covered by biological soil crusts (BSC), which stabilize the surface and prevent desertification. Political discussions in Israel suggest transferring a large part of this sand belt to the Gaza Strip within a final peace accord. Inappropriate land uses may lead to destruction of the BSC and initiate desertification, as already occurring in parts of the Gaza Strip. In this interdisciplinary project the influence of environmental factors on the vitality, stability and the recovery potential of the BSC will be investigated in order to evaluate the carrying capacity of this fragile landscape, in relation to rainfall, soil and relief conditions. A transect stretching from the Mediterranean coast in the Palestinian Gaza Strip (370 mm rainfall) to 65 km southwards in Israel ( Nizzana , less than 100 mm rainfall) has been selected. The interactions of molecular biological, physiological, physical and soil chemical processes, expressed in specific characteristics of the BSC and the underlying soil, will be assessed from the molecular to the landscape scale.
The aim of P2 within the Research Unit 'The Forgotten Part of Carbon Cycling: Organic Matter Storage and Turnover in Subsoils (SUBSOM)' is to contribute to the understanding of the different sources and stabilization processes of subsoil organic matter. This will be achieved by the analysis of the soil organic matter composition in topsoil versus subsoil by 13C NMR spectroscopy in bulk soils as well as organo-mineral associations. This will be done on a number of soil profiles differing in parent material and mineralogy and therefore also in the relevance of organo-mineral associations for subsoil C stabilization. In addition, a specific sampling approach will allow to differentiate three zones associated with the dominating effect of (1) leaching of DOC (the 'bulk soil' between trees), (2) root litter decomposition (the 'root-affected zone'), and (3) direct rhizodeposition of root exudates (the 'rhizosphere' sensu strictu). The contribution of above-ground versus below-ground litter is differentiated by the analysis of cutin and suberin biomarkers. Organic matter derived from microbial sources will be identified by the microbial signature of polysaccharides in the subsoil through the analysis of neutral sugars and amino sugars. Organo-mineral associations will be further characterized by N2-BET analyses to delineate the coverage of the mineral phase with organic matter. With these analyses and our specific analytical expertise at the submicron scale (nanoSIMS) we will participate in selected joint experiments of the research unit.
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.
Research in 'silviculture' and 'forest economics' very often takes place largely independent from each other. While silviculture predominantly focuses on ecological aspects, forest eco-nomics is sometimes very theoretic. The applied bioeconomic models often lack biological realism. Investigating mixed forests this proposal tries to improve bioeconomic modelling and optimisation under uncertainty. The hypothesis is tested whether or not bioeconomic model-ling of interacting tree species and risk integration would implicitly lead to close-to-nature forestry. In a first part, economic consequences of interdependent tree species mixed at the stand level are modelled. This part is based on published literature, an improved model of timber quality and existing data on salvage harvests. A model of survival over age is then to be developed for mixed stands. A second section then builds upon data generated in part one and concentrates on the simultaneous optimisation of species proportions and harvest-ing ages. It starts with a mean-variance optimisation as a reference solution. The obtained results are compared with data from alternative approaches as stochastic dominance, down-side risk and information-gap robustness.
Water, carbon and nitrogen are key elements in all ecosystem turnover processes and they are related to a variety of environmental problems, including eutrophication, greenhouse gas emissions or carbon sequestration. An in-depth knowledge of the interaction of water, carbon and nitrogen on the landscape scale is required to improve land use and management while at the same time mitigating environmental impact. This is even more important under the light of future climate and land use changes.In the frame of the proposal 'Uncertainty of predicted hydro-biogeochemical fluxes and trace gas emissions on the landscape scale under climate and land use change' we advocate the development of fully coupled, process-oriented models that explicitly simulate the dynamic interaction of water, carbon and nitrogen turnover processes on the landscape scale. We will use the Catchment Modelling Framework CMF, a modular toolbox to implement and test hypothesis of hydrologic behaviour and couple this to the biogeochemical LandscapeDNDC model, a process-based dynamic model for the simulation of greenhouse gas emissions from soils and their associated turnover processes.Due to the intrinsic complexity of the models in use, the predictive uncertainty of the coupled models is unknown. This predictive (global) uncertainty is composed of stochastic and structural components. Stochastic uncertainty results from errors in parameter estimation, poorly known initial states of the model, mismatching boundary conditions or inaccuracies in model input and validation data. Structural uncertainty is related to the flawed or simplified description of natural processes in a model.The objective of this proposal is therefore to quantify the global uncertainty of the coupled hydro-biogeochemical models and investigate the uncertainty chain from parameter uncertainty over forcing data uncertainty up the structural model uncertainty be setting up different combinations of CMF and LandscapeDNDC. A comprehensive work program has been developed structured in 4 work packages, that consist of (1) model set up, calibration and uncertainty assessment on site scale followed by (2) an application and uncertainty assessment of the coupled model structures on regional scale, (3) global change scenario analyses and finally (4) evaluating model results in an ensemble fashion.Last but not least, a further motivation of this proposal is to provide project results in a manner that they support planning and decision taking under uncertainty, as this proposal is part of the package proposal on 'Methodologies for dealing with uncertainties in landscape planning and related modelling'.
bifa hat ein Vorhaben für die G8- Staaten bearbeitet, in dem die Entwicklungen in Deutschland innerhalb der neun Handlungsfelder ( Actions ) des Kobe 3R Action Plan dargestellt werden. Mit der 3R-Initiative beabsichtigen die G8-Staaten seit 2004 eine bessere Verankerung der Nachhaltigkeit im Umgang mit Rohstoffen durch die stärkere Förderung der drei Prinzipien Reduce, Reuse, Recycle , abgekürzt 3R , in den nationalen Abfallwirtschaftspolitiken. Im Rahmen der Beauftragung untersuchte bifa, welche Punkte aus dem Kobe 3R Action Plan bereits hinreichend durch bestehende Entwicklungen bzw. ergriffene Maßnahmen abgedeckt sind, bei welchen Aktionen noch Lücken bestehen und wie diese Lücken gefüllt werden können. Legt man die drei Zielsetzungen des Kobe 3R Action Plan und die ihnen zugeordneten Handlungsfelder als Prüfraster über die deutsche Abfallwirtschaftspolitik, lässt sich ein sehr hoher Erfüllungsgrad feststellen. Ein erheblicher Teil der vorgeschlagenen Handlungsoptionen war in Deutschland bereits vor 2008 durch konkrete Maßnahmen umgesetzt worden. Für einen anderen Teil wiederum lässt sich der Ursprung, z. B. in Form eines ersten Gesetzentwurfs, auf die Zeit vor 2008 zurückdatieren, die Umsetzung durch die Veröffentlichung im Bundesgesetzblatt aber fand 2008-2011 statt. Einige Regelungen setzen Richtlinien oder Verordnungen der EU, die ihrerseits zum Teil auf Bestrebungen Deutschlands hin zustande kamen, in nationales Recht um. Mit dem in einer fortgeschrittenen Version vorliegenden Entwurf eines novellierten Kreislaufwirtschaftsgesetzes vollzieht Deutschland einen weiteren wichtigen Schritt hin zu einer Abfallwirtschaft, deren Markenzeichen insbesondere eine hohe Ressourceneffizienz ist. Dennoch verbleiben Optimierungspotenziale, zu deren Ausschöpfung bifa Vorschläge für das Bundesumweltministerium erarbeitet hat. Im Zuge des Projekts analysierte bifa u. a. die Importe und Exporte notifizierungspflichtiger Abfälle. Der Saldo hat sich den bifa-Analysen zufolge seit 1998 umgekehrt: Wurden 1998 noch etwa doppelt so viel notifizierungspflichtige Abfälle exportiert wie importiert, hat sich der Import seitdem vervierfacht und die Exporte sind sogar leicht gesunken. Ein wichtiger Grund ist die Verfügbarkeit von Behandlungs- und Verwertungskapazitäten von hoher Leistungsfähigkeit in Deutschland. Die Schadstoffentfrachtung von Abfällen aus Ländern mit einer wenig entwickelten Entsorgungsinfrastruktur führt jedoch innerhalb der deutschen Öffentlichkeit immer wieder zu Kontroversen. Methoden: Analyse und Moderation sozialer Prozesse.
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.
Comprehension of belowground competition between plant species is a central part in understanding the complex interactions in intercropped agricultural systems, between crops and weeds as well as in natural ecosystems. So far, no simple and rapid method for species discrimination of roots in the soil exists. We will be developing a method for root discrimination of various species based on Fourier Transform Infrared (FTIR)-Attenuated Total Reflexion (ATR) Spectroscopy and expanding its application to the field. The absorbance patterns of FTIR-ATR spectra represent the chemical sample composition like an individual fingerprint. By means of multivariate methods, spectra will be grouped according to spectral and chemical similarity in order to achieve species discrimination. We will investigate pea and oat roots as well as maize and barnyard grass roots using various cultivars/proveniences grown in the greenhouse. Pea and oat are recommendable species for intercropping to achieve superior grain and protein yields in an environmentally sustainable manner. To evaluate the effects of intercropping on root distribution in the field, root segments will be measured directly at the soil profile wall using a mobile FTIR spectrometer. By extracting the main root compounds (lipids, proteins, carbohydrates) and recording their FTIR-ATR spectra as references, we will elucidate the chemical basis of species-specific differences.
