Research question: Agri-environment schemes play an increasingly important role in European CAP (Common Agricultural Policy) to support biodiversity and environment in agricultural landscapes. They have been implemented since 1992 and now cost a yearly 1.7 billion Euro. Still, there is no conclusive evidence that these schemes actually do contribute to the conservation of particularly biodiversity. The primary objective of this project is to evaluate the (cost-) effectiveness of European agri-environment schemes in protecting biodiversity and to determine the primary processes that determine their effectiveness. This project furthermore aims to determine how CAP may be introduced in candidate EU-members without unacceptable loss of biodiversity. It will provide simple guidelines how researchers, governmental authorities may efficiently evaluate agri-environmental measures. Aim: Agri-environment schemes have been used to protect biodiversity and environment in agricultural areas since 1992. Their effectiveness has never been reliably evaluated. This project aims to evaluate the (cost-)effectiveness of agri-environment schemes with respect to biodiversity conservation in five European countries. It will determine the proper scales that have to be addressed for conservation efforts for a range of species groups. It will determine the most important environmental factors that influence the effectiveness of the schemes. Based on this, recommendations will be made how the effectiveness of schemes may be improved and simple guidelines will be produced how ecological effects of agri-environment schemes can be evaluated efficiently by governmental authorities or other institutions. The ecological effects of the introduction of CAP in a candidate EU-member will be investigated to reduce negative side effects of anticipated land-use changes Scientific methods: We will examine the effectiveness of agri-environment schemes by surveying pairs of fields: a field with an agri-environment scheme and a nearby field that is conventionally managed. In five countries, in each country in three areas, and in each area on seven pairs of fields the species richness of birds, plants and three insect groups (pollinators, herbivores, predators) will be determined. Effects of schemes on pollination efficiency and pest control will be examined using indicator communities. Correlative studies will examine the effects of landscape structure, land-use intensity and species pool on the effectiveness of agri-environmental measures. The spatial scale that is relevant to nature conservation efforts will be investigated via the spatial distribution of species groups. The results will be used to formulate recommendations how to improve the effectiveness of agri-environment schemes and to construct a set of simple guidelines how schemes can be evaluated efficiently yet reliably.

We study the effects of plants and root-associated fungi on wind erosion within the alpine environment of Tibet. China is one of the countries most affected by desertification processes and Tibet, in particular, a key region in desertification combat. The presented project focuses on the Barkha Plain surrounded by Mount Kailash and the Lake of Manasarovar (Ngari Prefecture). This Western Tibet region experienced little scientific attention but, nowadays, faces rapidly increasing touristic activities and expanding local settlements associated with socio-economic changes that are serious threats to the delicate ecological balance and potential triggers of desertification. It exists almost unanimous agreement that revegetation is the most efficient and promising strategy to combat wind erosion and desertification in the long term. However, re-colonising success is often poor, mainly under extreme environmental conditions. Compared to conventional practices, the approach of the presented project attains better accordance with natural succession processes and promises acceleration of both plant and soil development and, conclusively, more efficient desertification control. The project assesses the potential of native plants and symbiotic fungi to control wind erosion and desertification processes. It aims to identify key plants and fungi that increase soil aggregate stability and efficiently drive succession into a natural and self-maintaining cycle of the ecosystem. Furthermore, it provides crucial information for implementing environmentally compatible and cost-effective measures to protect high-elevation ecosystems against desertification. Within three successional stages (early, intermediate, late), field investigations are performed on the basis of Modified-Whittaker plots. Classic methods of vegetation analysis and myco-sociology are combined with analysis of distribution patterns at different scales (patchiness, connectivity). Comprehensive soil analysis is performed comprising grain size distribution, aggregate stability, pH as well as water and nutrient contents. Additionally, important parameters of wind erosion are measured concurrently and continuously to assess their magnitude and variability with respect to vegetation and soil at different levels of development. The parameters addressed, include sediment transport, air temperature, radiation, precipitation, relative humidity as well as speed and direction of wind. Surface moisture is recorded periodically and roughness described. Species and environmental parameters are checked for spatial correlation. Cutting edge technologies are applied in laboratory work, comprising molecular methods for fungal species identification and micro-tomography to analyse soil structure. Furthermore, successfully cultivated fungi and plants are subject of synthesis experiments and industrial propagation in view of practical implementation in restoration measures.
Methoden des terrestrischen Carbon Dioxide Removal (tCDR) wie Aufforstung und Biomasseplantagen werden zuweilen als effektive, 'grüne' und sichere Varianten des Klimaengineering (CE) verstanden wegen ihrer Möglichkeit, die natürliche CO2-Aufnahme durch die Biosphäre zu erhöhen, und ihrer denkbaren ökonomischen Tragfähigkeit. Erkenntnisse aus der ersten Phase des CE-LAND-Projekts legen indes nahe, dass tCDR aufgrund schwieriger erdsystemischer und ethischer Fragen ebenso kontrovers wie andere CE-Methoden ist. CO2-Budgetierungen und rein ökonomische Bewertungen sind daher um profunde Analysen der natürlichen Begrenzungen, der Auswirkungen auf das Erdsystem mit damit verbundenen Unsicherheiten, der Tradeoffs mit anderen Land- und Wassernutzungen und der weitreichenden ethischen Implikationen von tCDR-Maßnahmen zu ergänzen. Analysen hypothetischer Szenarien der ersten Projektphase zeigen, dass effektives tCDR die Umwidmung großer Flächen voraussetzt, womit schwierige Abwägungsprozesse mit anderen Landnutzungen verbunden wären. Darüber hinaus zeigt sich, dass signifikante Nebenwirkungen im Klimasystem (außer der bezweckten Senkung der Weltmitteltemperatur) und in terrestrischen biogeochemischen Kreisläufen aufträten. CE-LAND+ bietet eine tiefergehende quantitative, räumlich explizite Evaluierung der nicht-ökonomischen Kosten einer Biosphärentransformation für tCDR. Potentielle Tradeoffs und Impakts wie auch die systematische Untersuchung von Unsicherheiten in ihrer Abschätzung werden mit zwei Vegetationsmodellen, einem Erdsystemmodell und, neu im Projekt, dynamischen Biodiversitätsmodellen analysiert. Konkret wird CE-LAND+ bisher kaum bilanzierte Tradeoffs untersuchen: einerseits zwischen der Maximierung der Flächennutzung für tCDR bzw. Biodiversitätsschutz, andererseits zwischen der Maximierung der Süßwasserverfügbarkeit für tCDR bzw. Nahrungsmittelproduktion sowie Flussökosysteme. Auch werden die (in)direkten Auswirkungen veränderten Klimas und tCDR-bedingter Landnutzungsänderungen auf Wasserknappheit (mit diversen Metriken und unter Annahme verschiedener Varianten des Wassermanagements) und Biodiversität quantifiziert. Die Tradeoffs und Impakts werden im Kontext von neben der Bekämpfung des Klimawandels formulierten globalen Nachhaltigkeitszielen - Biodiversitätsschutz, Wasser- und Ernährungssicherheit interpretiert - was sonst nicht im Schwerpunktprogramm vermittelt wird. Ferner wird das Projekt zu besserem Verständnis und besserer Quantifizierung von Unsicherheiten von tCDR-Effekten unter zukünftigem Klima beitragen. Hierzu untersucht es modellstrukturbedingte Unterschiede, Wachstum und Mortalität von tCDR-Pflanzungen unter wärmeren und CO2-reicheren Bedingungen und Wechselwirkungen zwischen tCDR-bezogenen Landnutzungsaktivitäten und Klima. Schließlich wird CE-LAND+ in Kooperationen innerhalb des Schwerpunktprogramms und mit einer repräsentativen Auswahl von Szenarien zur Evaluierung tCDR-bedingter Tradeoffs aus umweltethischer Sicht beitragen.
The CliSAP-Integrated Climate Data Center (ICDC) allows easy access to climate relevant data from satellite remote sensing and in situ and other measurements in Earth System Sciences. These data are important to determine the status and the changes in the climate system. Additionally some relevant re-analysis data are included, which are modeled on the basis of observational data. ICDC cooperates with the "Zentrum für Nachhaltiges Forschungsdatenmanagement "https://www.fdr.uni-hamburg.de/ to publish observational data with a doi.

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.
