Top down or Bottom up?

Transcription

1 Top down or Bottom up? Formal and informal elements of Climate Adaptation Governance in the Metropolitan Region of Hamburg Jörg Knieling Lisa Kunert Sonja Schlipf Philipp Schuster HafenCity University Hamburg BaltCICA Final Conference 18/19 January 2012, Helsinki

2 Structure 1. Climate Adaptation Governance and Implementation Strategies 2. Instruments for Bottom up and Top down Adaptation in the Metropolitan Region of Hamburg 3. Resumee and Conclusion

3 Climate Adaptation Governance Specific characteristics and challenges of climate change intermediate multilevel Crosssectoral Longterm Uncertainty

4 Different strategies of implementation Bottom Up Top Down

5 Climate Change in the MRH: Vulnerability assessment Hamburg How does climate change affect the city/region? Region vulnerable towards: Floods, storm surges, sea level rise Urban heat islands Extreme weather events

6 Climate Adaptation Governance: Different types of instruments Szenario workshops Regional planning and Climate Change: Feasibility study on resilient settlement structures. Climate Adaptation Colloqiums Time to adapt? BaltCICA Summer School Public Online discourse for Flood Protection and Climate Change Workshop Climate Adaptation in Social Sciences

7 Szenario Workshops MRH Visions (Top 5): Ongoing awareness-raising and creation of adaptive attitudes Long-range consensus among federal states in the MRH Development of multi- functional spaces Development of win-win solutions between environmental and societal interests. Launching a Planning Association MRH

8 Szenario Workshops MRH Exemplary adaptation measures for MRH (rural areas, environment and agriculture): Extracting dwelling mounds Designation of flooding areas Use of flood resilient crops De-sealing surfaces Multifunctional land use for agriculture Extracting drainage systems Scenario methode in next Regional Conference: Ongoing adaptation process for MRH and Northern Germany

9 Szenario Workshops MRH Attended by the mayor, politicans, students, teachers and citizens Creation of an overall concept for adaptation to climate change which is going to be implemented Innovative tourism concept, taking into account the changing climate Ventilation and implementation of pumps to reduce water vulnerability towards alguae

10 Climate Adaptation Colloqiums Time to adapt? Aims & outcomes: Lectures about good practice in adaptation National and international examples of handling climate change Raising awareness among stakeholders, students and interested people

11 BaltCICA Summer School 55 participants from different disciplines Thematic focus: Climate change in cities and regions Presenting results from the BaltCICA case studies Academic background of the participants Introducing innovative methodological approaches how to face climate change 2 work modules with emphases on creativity and interaction/ cooperation

12 BaltCICA Summer School Creative approach: Metropolitan Lab Designing Future Metropolitan Region in line with Climate Change Innovative approaches and measures with no boundaries Cooperational approach: Scenario Workshop and Role Play Finding consensus among participating stakeholders Developing (notional) Adaptation Strategy for the Metropolitan Region of Hamburg

13 BaltCICA Summer School Evaluation 40% 30% 30% 33% Do the topics of the Summer School help you for your own work/study? 20% 10% 0% 15% Yes, totally Yes 11% 11% A little Hardly Not at all To what extend is the thematic main focus (adaptation to climate change) already anchored in your professional activities? 30% 20% 10% 0% 26% 26% 19% 19% 11%

15 Role of Climate Change Adaptation in Spatial Planning National Level Regional Level Local Level Netherlands Germany Finland Lativa Legislation National Programme Regional Legislation Regional Planning Master plan Development plan Legislation Legislation Legislation Regional Legislation Regional Planning Master Plan Master plan Regional Planning Master Plan Detailed plan Detailed Plan Detailed Plan Detailed Plan Role of Climate Adaptation in Spatial Planning Climate Change adaptation by spatial planning (specific documents) key role of spatial planning is yet to be implemented (DAS) role is mentioned but not specifically specified national adaptation strategy is prepared

16 Analysis of 24 regional land use plans Influence on resilient settlement structures Designations for defined areas Determination of land use as a goal (Ziel Vorranggebiet) Determination of land use to be balanced (Grundsatz Vorbehaltsgebiet) Further land use determinations Risk maps (flood prevention) Written designations for the whole region as Ziel (goal) or Grundsatz (to be balanced by the municipalities) Quelle: Innenministerium Schleswig Holstein 1998

17 Influence of land use planning on resilient settlement structures Regulating flood prevention Flexible river systems Settlement structures that withstand floods and inundations Minimizing heat island effects Reduction of land consumption by an effective landscape development Unsealing by brownfield development Regulation of open spaces Multifunctional designation (Grünzug / Grünzäsur)

18 Region of Tide-Elbe Pinneberg Vulnerability: Floods, storm surges, sea level rise Urban heat islands Extreme weather events

19 Conclusiones Open space important for flood prevention and the reduction of heat island effects More information about the heat island effect in Hamburg is needed Development of settlements along the axis Combination of flood prevention areas and the connection of ecological protection areas Less settlement development in the marshlands Quelle: Innenministerium Schleswig Holstein 1998

20 3. Summary and conclusions Adaptation to Climate Change in the MRH: Ongoing process but Analysis and sample of different implementation approaches (top down and bottom up) Analysis and sample of different governance instruments Introduction of scenario methode in ongoing adaptation process

21 Summary and conclusions Remaining challenges MRH:: Vision of Hamburg in 2100 Ongoing paradigm shift of living with water Mixing both top-down and bottom up approaches Finding consensus among federal states Maintaing multi-level and cross-sectoral approach
