The Northwest of Germany is characterized by lively and modern cities and a rough landscape of coastal wetlands and moors. The flat land in the Northwest has long become a centre of logistics and harbor industry, of food production, and expertise in aerospace, energy and environmental technology. The region is one of Germany’s most dynamic industrial locations. nordwest2050 focuses on the Metropolitan Region Bremen-Oldenburg in the Northwest of Germany, a region with more than 2.3 million inhabitants
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.
A reestablishment of Fucus vesiculosus where it is locally vanished would be an indicator for improved water quality. Thus the Agency for Agriculture, Environment and Rural Areas of Schleswig - Holstein (LLUR) is thinking about opportunities to resettle F. vesiculosus. On behalf of RADOST project, the tolerance of early fucoid life stages towards thermal stress was analysed and after four days of thermal treatment a high percentage of the treated fucoid offspring survived. It might be that inside species genotypes exist which are less sensitive against future environmental changes.
Over the last decades, Fucus vesiculosus, an ecologically important macroalga in the German Baltic Sea, has shown a massive retreat from the deeper zones of its former distribution presumably due to low light co-acting with other potential stressors such as high temperature, fouling, and grazing. In shallow water F. vesiculosus may be exposed to high water temperatures during summer seasons. Intensity and frequency of heat waves are expected to increase due to climate change which could potentially affect all fucoid life stages. Early life stage processes (fertilization, germination) are often considered particularly sensitive to stress. If the mortality caused by a first heat wave in a genetically diverse population selects for stress resistance, we would expect the survivors to be less sensitive to a second heat wave or possibly even to other stressors like feeding pressure.
In the present study, the mortality of early post-settlement stages of F. vesiculosus under thermal stress and the sensitivity of survived recruits against a proximate stressor (feeding pressure, second heat wave) were analysed by laboratory experiments. The mortality of early fucoid life stages at 25°C, compared to their mortality at 15°C was significantly higher. Regrettably, the ensuing assessment of feeding impact by Idotea baltica and Hydrobia ulvae on the surviving germlings could not be analysed since the two consumer species unexpectedly avoided feeding on the young stages of F. vesiculosus. During the second thermal stress experiment fucoid offspring which was genetically preselected by high temperature (first heat wave: 25°C) differed not significantly in sensitivity from fucoid offspring without prior stress.
This work deal with a comparison between the common
"bathtub method" and a state-of-the-art hydrodynamic model, called MIKE21 HD Flow Model, for modelling storm surges. The aim of this study is to work out the differences between both approaches and to find out how probable differences look like. There is the question if the "bathtub method" represents flooding adequate or, if the consideration of physics by hydrodynamic models makes a major difference and displays maybe the "real" risk of
inundations. This work tries to underline the differences between those two approaches, where the strengths and weaknesses are and what influence those differences have for an inundation analysis. The investigation was made on a digital elevation model for the study area of Kiel, the capital city of the state Schleswig-Holstein in Germany. The two approaches were made on data for a small storm surge on the basis of water-level-change and wind-regime data from 2010.
Adaptation to climate change requires the implementation of new and revision of existing policies in order to change collective behaviour in a way that reduces vulnerability to the impacts of climate change. At the same time, the efficiency of environmental governance has been questioned due to perceived deficiencies in implementation in the past. As a consequence, it is observed that high levels of adaptive capacity are often not used for adaptive action, and therefore communities remain vulnerable. This thesis is looking at the socio-cognitive dimension of adaptation from the perspective of socio-cultural construction of values and practices that influence risk perceptions and behavioural intentions in coastal management and adaptation to climate variability and change. The construction of values and practices is analysed through discursive fields on the respective topics in local media from three states on the US mid-Atlantic coast.
The restaurant trade is increasingly facing delivery bottlenecks as a result of climate change, which may even cause interruptions of the production of food products. Due to reduced yields and at the same time increased resource requirements, cost pressures are rising. In order to face these challenges in a timely manner, the DEHOGA East Friesland & Weser-Ems District Association is developing climate adaptation strategies for the restaurant trade. In the present project, the effects of climate change are analyzed, and specific solution paths for the restaurant trade are developed and communicated within the DEHOGA District Association.
The Protestant Hospital Service GmbH (eks) was founded in 1997. The catering service of the KS includes not only the delivery to hospitals, rehabilitation centers and senior citizens facilities, but also catering services for factory canteens, kindergartens and schools. The EKS has a total of 250 staff and prepares approximately 3500 meals per day in the cook-and-chill procedure. This permits it to de-link food preparation and food distribution, both spatially and chronologically. As a result of climate change, the availability and unquestioned quality of raw materials is ever more difficult to ensure. For these reasons, the KS is supplemented the existing concept of out-of-home catering with a new line of organically and regionally produced products.
The establishment of a consciousness for climate change processes and the necessary changes for climate-adapted agriculture and a climate-adapted food industry will require communications and interaction at the level of economic clusters, in order to initiate exchange and cooperation alliances by means of targeting network formation. The Oldenburg Münsterland Agriculture and Food Forum (AEF) is an association of 75 businesses in the agriculture and food sector which operates as an interface between the scientific community and everyday practice. In close cooperation with the Carl von Ossietzky University of Oldenburg, key issues for regional climate adaptation measures have been developed on the basis of scientific ascertainments and practice-oriented needs.
A farmer and turkey raiser in Varrel (Oldenburg, Germany) has set up an absorption cooling plant on his farm which provides the necessary air-conditioning for his stall on hot summer days with the help of the waste heat from a biogas plant. The biogas plant itself is fueled partially by turkey manure, and the waste heat from the cogeneration plant linked to the biogas facility is used to operate an absorption cooling plant. The absorption cooling experts from the companies SolarNext AG and Meyer Kühlanlagen, together with the University of Bremen are working on implementation. The project has been subsidized to the tune of €185,000 by the Federal Ministry for Education and Research. The farmer’s self-payment share amounted to €45,000.
