Workshop "Energiepflanzenanbau - ökologische Folgen für die Landschaft"
IFZ der Justus-Liebig-Universität Gießen, 29.-31. Mai 2008
Vom 29.-31. Mai 2008 fand im IFZ der Justus-Liebig-Universität Giessen (Heinrich-Buff-Ring 26-32) der Workshop "Energiepflanzenanbau: Folgen für die Landschaft" statt.
Im Rahmen des Workshops wurden zwei Impulsvorträge gehalten zu:
- Praxis und Perspektiven des Energiepflanzenanbaus (Dr. Joachim Fischer, Ingenieurgemeinschaft Witzenhausen Fricke & Turk GmbH; 29.5.08, 13 Uhr)
- Wirtschaftlichkeit des Energiepflanzenanbaus (Dr. Jochen Kantelhardt, Wirtschaftslehre des Landbaus, TU München; 30.5.08, 8:30 Uhr)
Im Übrigen erfolgte am 29. und 30. Mai Kleingruppenarbeit zu (potenziellen) Folgen des Energiepflanzenanbaus für
- Biodiversität
- Abiotische Ressourcen.
Einige der Teilnehmer berichteten in Kurzbeiträgen von eigener Forschungsarbeit zum Themenbereich Energiepflanzenanbau.
Am 31. Mai fand eine Exkursion zum Energiepflanzenanbau in Südhessen statt.
Fotos zu dieser Exkursion finden Sie hier.
Im Workshop genutzte Literatur und Bookmarks finden Sie unter www.bibsonomy.org in der Gruppe "bioenergyworkshop".

GfOE Annual Conference 2007 - Symposium 'Landscape Structure and Species Dispersal'
University of Marburg, September 10-14, 2007
Chair: Rainer Waldhardt, Justus-Liebig-University Giessen
The relationship between landscape structure and biodiversity is one of the core issues in landscape ecology. Evidence is numerous that biodiversity measures such as species composition and species richness of ecosystem patches are affected by landscape configuration. For a better understanding of biodiversity pattern at the landscape scale, multiple spatial scales need to be considered and multiscale approaches are evident. In this context, research on processes of species dispersal may contribute to a better understanding of ecosystem functioning, particularly in the context of global change. Hence, you are invited to present and discuss empirical and experimental studies on landscape effects on species dispersal.
Palmerston North (New Zealand), February 12-16, 2007
Organiser: Rainer Waldhardt, Justus-Liebig-University Giessen
Intensification of agricultural practices (e.g., fertilisation, herbicide application), new agricultural techniques (e.g., precision farming) and branches of production (e.g., production of renewable energy sources), and land abandonment directly and indirectly affect the vegetation on agricultural land and also adjacent (near-)natural vegetation. Further, changes in agricultural land-use / land-cover pattern may result in vegetation changes at broader spatial scales. In this context, the symposium aims to provide an overview of studies that allow to detect and to quantify the main factors contributing to vegetation changes at the patch to the regional scale. You are invited to present empirical research and modelling approaches.

GfOE Annual Conference 2006 - Symposium 'Modelling' on Landscape Ecology and Ecological Theory
University of Bremen (Germany), September 11, 2006
Landscape changes: Modelling future biodiversity at the landscape scale
Chairs: Dorothea Kampmann (Agroscope, Zürich-Reckenholz) and Rainer Waldhardt (Justus-Liebig-University Giessen)
All over the world, landscape changes severely affect biodiversity. These changes may result from natural and/or anthropogenic processes. E.g., human impact such as deforestation or intensive agricultural land use has reduced genetic diversity, species richness, the diversity of ecosystems, and also ecosystem functioning. Consequently, the question of how ecologically sustainable land use can be achieved is one major challenge for e.g., land users, policy makers and, not least, for ecologists and nature conservationists.
In this context, prognoses on future biodiversity resulting from land-use changes are urgently needed. Furthermore, evaluations of the effects of short- and long-term natural landscape changes (e.g., caused by catastrophes) are essential in predicting potential changes in the world’s biodiversity. In general, these biodiversity prognoses have to be based on spatial and temporal models.
The symposium aims at an overview of predictive models at the landscape scale. We especially invite you to present and discuss GIS based modelling approaches that allow displaying the spatial extent and patterns, and/or the time dependency of effects on biodiversity measures. Comparative studies from contrasting landscapes are also most welcome.

Driving forces of species diversity at the landscape scale
GfOE Annual Conference 2005 in Regensburg (Germany) - Symposium on Landscape Ecology
Chairs: Hans Jürgen Böhmer (University of Bonn) and Rainer Waldhardt (Justus-Liebig-University Giessen)
At the landscape scale, the diversity of plant and animal species and changes in species diversity have resulted from the impacts of driving forces that may be related to e.g., spatio-temporal patterns of site conditions and land-use practices, and processes of biotic interaction. With respect to the functional system of the landscape, intrinsic and extrinsic driving forces may be differentiated. The relationships between driving forces and their relative impacts on the species diversity may differ between landscapes and even within a landscape. Furthermore, effects may vary in time. Besides other reasons, a deepened knowledge and functional understanding of the driving forces of species diversity at the landscape scale is urgently needed in the development and implementation of sustainable land uses.
Given this background, the symposium aims to present an overview on the state-of-the-art in biodiversity research that allows to detect and quantify the driving forces of species diversity in a given landscape for a given time period. We especially invite you to present and discuss quantitative empirical studies that investigate the relative impacts of driving forces, their relationships and functionality, and / or the spatio-temporal specificity of the effects of driving forces.
