Abstracts book of oral presentations and poster contributions for the mid-term conference of the Interreg IVB NWE project ForeStClim. The international conference took place in Nancy (France) from 20. to 22. September 2010. The topics of the conference sessions were as follows:rnSession 1: Projecting forest sites and stand shiftsrnSession 2: Climate change and water: modelling across spatial and temporal scalesrnSession 3: Addressing climate change in practical silvicultural decision support
In past years, desertification and land degradation have been acknowledged as a major threat to human welfare world-wide, and their environmental and societal implications have sparked the formulation of the UN Convention to Combat Desertification (UNCCD). Any measure taken against desertification, or the design of dedicated early warning systems, must take into account both the spatial and temporal dimensions of process driving factors. Equally important, past and present reactions of ecosystems to physical and socio-economical disturbances or management interventions need to be understood. In this context, remote sensing and geoinformation processing support the required assessment, monitoring and modelling approaches, and hence provide an essential contribution to the scientific component of the struggle against desertification. Supported by DG Research of the European Commission, the Remote Sensing Department of the University of Trier convened RGLDD to promote scientific exchange between specialists working on the interface of remote sensing, geoinformation processing, desertification/land degradation research and its socio-economic implications. Although targeted at the scientific community, contributions with application perspectives were of crucial importance and both an overview of the current state of the art as well as operational opportunities were presented. Hosted at the Robert-Schuman Haus in Trier, the conference gained widespread attention and attracted an international audience from all parts of the world, which underlines the global dimension of land degradation and desertification processes. Based on a rigorous review of submitted abstracts, more than 100 contributions were accepted for oral and poster presentation, which are found in these proceedings edition in full paper form.

Die Extraktion relevanter Abflussbildungsprozesse und deren adäquate Abbildung in Modellen gewinnt im Rahmen eines integrierten Managements ganzer Einzugsgebiete immer mehr an Wert, weil die Hochwasserentstehung und die Dynamik der mit dem Wasser transportierten Schadstoffe entscheidend von der Abflussbildung gesteuert werden. Ziel eines Flussgebietsmanagements ist die Verbesserung der Funktionsfähigkeit eines Einzugsgebiets. Das Bereitstellen verlässlicher Entscheidungsgrundlagen für die praktische Umsetzung einzugsgebietsbezogener Maßnahmen erfordert die Einbindung der komplexen, interagierenden Prozesse. Modelle können bei der Analyse und integrierenden Betrachtung der in der Regel nichtlinearen und rückgekoppelten Prozesse einen besonderen Stellenwert einnehmen. So können sie zu Prognosen der Auswirkungen geplanter Maßnahmen und der Veränderungen von natürlichen Randbedingungen herangezogen werden. Die erforderliche Genauigkeit der Prozessabbildung und welche Art von Modellen genutzt wird ist dabei abhängig von der jeweiligen Fragestellung und der untersuchten Skala. Insgesamt ist es erforderlich, den Unsicherheiten der Modellergebnisse einen angemessenen Stellenwert im Hinblick auf ein langzeitliches, optimales Management einzuräumen. Hierzu zählen auch Fragen der Verfügbarkeit, Zuverlässigkeit und Repräsentativität von Daten auf Einzugsgebietsebene. Eine enge Kopplung der Prozessforschung und der Auswertung mittels hydrologischer Modellierung ist in diesem Kontext für eine Beurteilung von Richtlinien und Maßnahmenvorschlägen im Flussgebietsmanagement notwendig.
In addition to flood disasters on major rivers, damage caused by the flooding of smaller and medium-sized tributaries is also of considerable significance. To ensure that flood protection measures are effective, engineering flood prevention measures on the rivers must be supported by integrated catchment management. This includes decentralised water retention measures implemented in the sectors of forestry, agriculture and in residential areas. Within this scope new instruments have to be elaborated and introduced, such as GIS-based systems and systems for the evaluation of economic consequences and eco-efficiency of flood damage precaution measures associated with land-use. These are extremely significant for improving information management, the prevention of advice to the general public and for the acceptance of flood precaution measures. The conference intends to promote scientific exchange between specialists working on all areas concerning integrated catchment management. This includes the methodology for identification of catchment types prone to flooding hazards, the control and validation of land-use concepts for decentralised water retention as well as its combination and upscaling procedures up to mesoscale catchments. As catchment management is not only the concern of natural scientists the strategies for enhancing catchment management and the development of decision-support tools will also be important topics of the conference. ***Addenda *1.
