Als zweiter Teil einer Anpassungsstrategie für die öffentlichen Lübecker Häfen an den Klimawandel greift der Bericht die Auswirkungen einzelner Klimaparameter für die Hafenwirtschaft erneut auf, um Schlussfolgerungen über eine Anpassungsnotwendigkeit der Infra- und Suprastruktur der Lübecker Häfen darstellen zu können.
Anpassungen baulicher Art, notwendig aufgrund der skizzierten klimatischen Veränderungen, ziehen erhebliche monetäre Investitionen nach sich, die für die Akteure im Extremfall die Wirtschaftlichkeit der betroffenen Unternehmen infrage stellen können. Besonders durch die Vielzahl von möglichen Klimaszenarien, kann eine konkrete Anpassungsnotwendigkeit zum jetzigen Zeitpunkt nur schwer vorherbestimmt werden. Die Herausforderung besteht darin, aus der breiten Spanne der möglichen Klimaentwicklungen allgemeine Tendenzen zu entwickeln, die eine entsprechende Anpassung rechtfertigen.
Dieser Bericht soll den öffentlichen Lübecker Häfen als Leitfaden für einen möglichen Anpassungsbedarf dienen und ihnen ferner eine erst Indikation bezüglich zu erwartender monetärer Auswirkungen liefern.
Das Poster zur RADOST-Abschlusskonferenz im April 2014 fasst Ergebnisse des RADOST-Fokusthemas Erneuerbare Energien zusammen. Als Beispiel wird die oberflächennahe Geothermie besonders berücksichtigt.
Managing the impacts of climate change is an important issue for sustainable urban planning. A large range of economic activities influence urban climate and are influenced by climate change itself. The impacts of climate change on power plants, manufacturing processes and business locations as well as adaptation options should be analysed to understand the vulnerability to climate change. The seriousness of the potential impacts of
climate change on enterprises requires new concepts and innovative products for flexible and robust adaptation options. The analysis of the impacts of climate change on enterprises and potential adaptation measures is the basis of the research framework of a “climate-focused economic development” within the networking and research project dynaklim. A differentiated vulnerability assessment enables us to define and identify strategies of adaptation in the means of organisational, marked-focused and technical developments.
A statistical downscaling method has been developed to produce highly resolved precipitation data from regional climate model (RCM) output, using the model CLM (2 runs, scenario A1B). The procedure is based on the analogue method with the predictors precipitation (daily sums on CLM grid points) and objective weather types (DWD). Analogue days of the time period 2001-2009 are searched using corrected and adjusted data of radar Essen and DWD measurements of objective weather types. The radar data is used to produce high-resolution precipitation data sets (1km², 5min) with realistic spatial and temporal correlations for three catchments in North Rhine-Westphalia. Results in
the reference period (1961 - 1990) are examined using extreme value statistics and compared to corrected station data. Data sets of the near and the far future (2021-2050, 2071-2100) are analysed with respect to future trends, and uncertainties of the downscaling procedure are discussed.
Rainfall statistics are composed based on data gained by precipitation measurements and from climate models. These statistics are carried out for both periods in the past and the future. When analysing the time series, different trends can be seen in the measured data of the past and the model data for future periods. Influences on the statistically determined precipitation amounts caused by changes can be neglected for past periods. However, significant increases of the statistical precipitation amounts can be observed for the future. Here a pragmatic approach is presented, showing how to consider possible increases in the statistical precipitation amounts – due to the climate change signal – in the dimensioning of water management systems.
The precipitation data of the Regional Climate Model CLM are used for the water management impact models within the dynaklim networking and research project. For this purpose, it is necessary to apply a bias correction to the CLM
precipitation data. First, the bias assessed for varying temporal resolutions and precipitation characteristics is described. Subsequently, a method for the bias correction is introduced. The developed methodology is a modified form of the socalled
quantile mapping. The focus lies on the corrections of the dry days and the heavy rainfall events. They are considered separately, deviating from other quantile mapping procedures.
Literaturrecherche und Analyse der Bewirtschaftungspläne von 18 deutschen und europäischen Flussgebietseinheiten. Der Bericht untersucht inwieweit die zu erwartenden Auswirkungen des Klimawandels in die ökonomischen Analysen gemäß Wasserrahmenrichtlinie integriert wurden.
In light of projected climate change impacts in the Baltic Sea region, there is a strong need for enhanced understanding about adaptation needs. In this regard, the role of local level decision makers will be crucial to the success of such adaptation strategies. This primer aims to provide local decision makers with insights and knowledge on the subject. This primer has been prepared as part of the project RADOST (Regional Adaptation Strategies for the
German Baltic Sea Coast), which is funded by the
German Federal Ministry of Education and Research.
