Evaluating current European agri-environment schemes to quantify and improve nature conservation efforts in agricultural landscapes (EASY)

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.

Bodenschutz- und Altlasteninformationssystem

Das Landesamt für Umweltschutz führt nach § 11 Ausführungsgesetz des Landes Sachsen-Anhalt zum Bundes-Bodenschutzgesetz (BodSchAG LSA) ein Bodenschutz- und Altlasteninformationssystem. Das Bodenschutz- und Altlasteninformationssystem (ST-BIS) enthält beschreibende Informationen (Metainformationen) über Daten, deren Kenntnis für die Erfüllung bodenschutz- und altlastengesetzlicher Aufgaben von Bedeutung sein kann. Dieses Metainformationssystem gibt Auskunft darüber, wer Daten besitzt, wie man Sie erhält und um was für Daten es sich handelt. Das ST-BIS wird im Internet geführt. Die Informationen für das ST-BIS stellen die Behörden dem LAU auf Anforderung gebührenfrei zur Verfügung.

Schwerpunktprogramm (SPP) 1488: Planetary Magnetism (PlanetMag), Structure and electronic transport properties of metallic liquids at conditions of planetary cores

Electrical conductivity is a key parameter in models of magnetic field generation in planetary interiors through magneto-hydrodynamic convection. Measurements of this key material parameter of liquid metals is not possible to date by experiments at relevant conditions, and dynamo models rely on extrapolations from low pressure/temperature experiments, or more recently on ab-initio calculations combining molecular dynamics and linear response calculations, using the Kubo-Greenwood formulation of transport coefficients. Such calculations have been performed for Fe, Fe-alloys, H, He and H-He mixtures to cover the interior of terrestrial and giant gas planets. These simulations are computationally expensive, and an efficient accurate scheme to determine electrical conductivities is desirable. Here we propose a model that can, at much lower computational costs, provide this information. It is based on Ziman theory of electrical conductivity that uses information on the liquid structure, combined with an internally consistent model of potentials for the electron-electron, electron-atom, and atom-atom interactions. In the proposal we formulate the theory and expand it to multi-component systems. We point out that fitting the liquid structure factor is the critical component in the process, and devise strategies on how this can be done efficiently. Fitting the structure factor in a thermodynamically consistent way and having a transferable electron-atom potential we can then relatively cheaply predict the electrical conductivity for a wide range of conditions. Only limited molecular dynamics simulations to obtain the structure factors are required.In the proposed project we will test and advance this model for liquid aluminum, a free-electron like metal, that we have studied with the Kubo-Greenwood method previously. We will then be able to predict the conductivities of Fe, Fe-light elements and H, He, as well as the H-He system that are relevant to the planetary interiors of terrestrial and giant gas planets, respectively.

Schwerpunktprogramm (SPP) 1006: Bereich Infrastruktur - Internationales Kontinentales Bohrprogramm, Sub project: Bündel-Antrag Ohrid-See: Evolutionary, geological, and environmental history of Lake Ohrid (EGEL)

Lake Ohrid is a large (360 km2) and deep (289 m) lake of tectonic origin and is shared between the Republics of Macedonia and Albania. Biological and biogeographical studies of the lake revealed an outstanding degree of endemism and suggest a Pliocene origin of Lake Ohrid, making the lake the oldest one in Europe. The high age and the high degree of endemism make Lake Ohrid a first class site to investigate the link between geological and biological evolution in ancient lakes. Given its importance as refugium and spreading centre, the lake was declared a UNESCO world heritage site in 1979, and included as a target site of the International Continental Scientific Drilling Program (ICDP) already in 1993. The political situation in the Balkan in the mid 1990ies, however, hampered further establishment of Lake Ohrid as potential ICDP site. This proposal bundle seeks funds for the detection of the timing of major evolutionary events, the investigation of the origin, the sedimentological inventory, neotectonic movements, and the paleoecology and paleolimnology of Lake Ohrid in order to develop a full ICDP proposal for deep drilling. Within the scope of this cover proposal funds for the coordination of the single proposals, for scientific exchange between the single bundle proponents, and for the data management are applied for.
