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.
Bakenhus Biofleisch GmbH is an organic meat processor and marketer which obtains its meat from its own and from other organic farms. All products – beef, pork, lamb and poultry – are produced according to the strict guidelines of organic food associations and in the traditions of the trade. Thus, Bakenhus Biofleisch GmbH is certified under the Naturland, Bioland and Demeter guidelines. Climate adaptation possibilities in the butcher’s trade are being developed in the context of the nordwest2050 Research Project.
Rather than focusing on climate-protection measures, the Bremen Cargo Distribution Center (GVZ Bremen) has identified measures for adaptation to climate change. In 2011 and 2012 the Institute of Shipping Economics and Logistics (ISL), together with the Bremen University of Applied Science, carried out a comprehensive empirical investigation of the effects of climate change on the logistics sector of the Metropolitan Region Bremen-Oldenburg in the Northwest. The results clearly show that the expected impacts of climate change could mean a new challenge, both for the GVZ and for individual companies at the Center.
One of the important parts of the final conference of ‘nordwest2050’ has been the scientific exchange sessions in the House of Science and the Industryclub Bremen. Contributions were based upon a call for papers from October 2013. The scientific committee received almost 100 abstracts where 36 were chosen for oral presentations and 15 for poster presentations (see overview tables below).
Four main topics were discussed in parallel workshops:
• Analysing Impacts and Assessing Vulnerabilities
• Designing and Testing Solutions for Regional Climate Adaptation and Resilience
• Implementing Climate Adaptation and Paths to a Resilient Future
• Resilience for Business: Climate Adaptation Challenge and Strategies of Sectors and Companies
The effects of climate change, such as ocean warming or the lowering of pH values, could lead to a reduction or migration of fishing stocks during the next 15 to 20 years, due to possible changes in the swarming and spawning behavior of the stocks. The bulk of the deep-freeze raw goods for the German fishing industry currently comes from countries which are not members of the EU. In the future, therefore, a more effective management of available resources and a stock-maintaining management of fish species for the supply of the market will be necessary.
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. Global warming may increase abiotic as well as biotic pressures and exacerbate environmental conditions in coastal ecosystems. The present study focussed on the effects of single or subsequently combined stressors on survival and palatability of juvenile F. vesiculosus. Fucoid offspring were exposed to high temperature and/ or feeding pressure. Feeding preference of Idotea baltica was quantified in a pellet assay calculated as an odds ratio. High temperature significantly impaired the survival of juvenile fucoids. Neither single nor combined stress considerably influenced the feeding preference of I. baltica. Surprisingly I. baltica strictly avoided pellets with juvenile F. vesiculosus compared to adult F. vesiculosus. Avoidance tended to be less pronounced in juvenile fucoids previously stressed by high temperature. Obviously grazing does not induce anti-herbivore defence, but rather the young plants appeared constitutively well-protected against isopod feeding. These results contradict the prevailing opinion that juvenile F. vesiculosus is more susceptible to herbivore grazing than adult F. vesiculosus.
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.
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.
