BREsilient - climate-resilient future city Bremen

Background and Goals

Extreme weather events such as heavy rain or flooding will increasingly affect Bremen as a place of life and business in the future. The goal of BREsilient is to prevent this and other consequences of climate change together. The research project builds on the Climate Adaptation Strategy, which identifies concrete key measures for adapting to climate change for Bremen and Bremerhaven.
Specifically, BREsilient has the following three objectives:
- Support the prioritization of adaptation measures, in particular on the basis of participation-oriented cost-benefit analyses and intersectoral coordination processes within the political-administrative system
- Preparation of the implementation of concrete adaptation measures in Bremen pilot projects within the investment-oriented real laboratories
- Implementation of theoretically and methodically sound coordination and participation processes with decision-makers, stakeholders and citizens

Steps in the process of adaptation to climate change

Step 2a: Identify and assess risks - climate effects and impact

Approach and results 

For the model areas "flood risk in the Pauliner Marsch", "heavy rain at the Blomedal Castle" and "climate impacts for the maritime economy and logistics" effects of climate change are identified and analyzed.

Step 4: Plan and implement measures

Measures and/or strategies 

Together with the local people, concepts and measures for dealing with the consequences of climate change are being developed in four model areas:
- Assess flood risk in the recreational, sports and leisure area Pauliner Marsch with local residents and interest groups and develop measures for risk prevention
- Assess heavy rainfall at Blomedal Castle in Bremen-Nord and develop a prevention concept together with the fire brigade and administration
- Analyze climate impacts for the maritime economy and logistics and discuss possible adaptation measures in a future workshop with industry representatives
- Carry out cost-benefit analysis for adaptation measures

Costs of the measures 

The Climate Adaptation Strategy for Bremen and Bremerhaven names numerous key measures for climate protection for people, the environment, buildings and infrastructure. For the implementation in the coming years, financial resources of the country and its two municipalities will be necessary. To compare the benefits of each implementation option, the process is accompanied by scientific cost-benefit analyzes and a regional economic study.

Step 5: Watch and evaluate adaptation (monitoring and evaluation)

Approach, objective and results of the monitoring and/or evaluation 

For the follow-up of the forms of participation used and for the identification of success factors in the design of participation processes / real laboratories for climate adaptation, a formative evaluation is carried out. The purpose of the evaluation is to determine to what extent the participation processes will lead to resilience-enhancing climate adaptation decisions and measures. In this way, a further basis for the decision is elaborated, which shows which climate adaptation measures can be successfully put into a planned implementation phase after the end of the three-year BREsilient project.
