2 AGENDA Part 1 Background Region Future climate and impacts Stakeholder Process in the region Part 2 Guide Climate Adaptation in planning procedures Findings and next steps

3 Part 1: Context/background

4 The Site Lower Weser Estuary Region

5 Vulnerabale Regions in Germany

6 climate projections northwest 2100 more storms warmer winters wind speed plus 3,8 % on average sea-level rise cm more storm tides heavy percipitation events critical water levels temperature rise plus 3 C etter winters hotter summers more rain during winters (plus 10-20%) extreme heat waves dry summers google maps

7 Impacts Temperature Extreme heat events Increase in heat related hospitalization Changes in ecosystems/biodiversity Precipitation Extreme Precipitation events Damage to properties Increasing cost of insurance due to stormwater Sea-level rise Increased potential for shoreline erosion Storm damages of infrastructure

8 Critical Infrastructure

9 Stakeholder Approach Tourism City- and Spatial Planung Agriculture develop Climate Adaptation strategies within sectors develop adaptation communication tools

11 Some key general findings Climate Change is known and is real. People think on Mitigation. Terms Adaptation nor Vulnerability and Resilience is in their mind. There are risk. Where are the chances? There are uncertainties - how to deal them? Adaptation (flood control, coastal protection,) is already on the way? So what is new? Nevertheless: we have to work on it more as a strategic and integrated approach. Water is a main theme for the region.

12 Part 2 Guide Climate Adaptation in Planning Procedures Guiding questions: 1. Do we need new planning instruments for Climate Adaptation? 2. If not, how to integrate Climate Adaptation into the already existing planning procedures? within the region? identification of first starting points and steps in urban and regional planning feedbacks from planners and final guide

13 Table of Contents 1. Regional climate scenarios and impacts 2. Urban & regional planning in the context of Climate Adaptation 3. Examples of urban and spatial planning implementing Climate Adaptation measures

14 Key Findings of Chapter 2 In many aspects spatial and urban planning play an important role in Climate Adaptation. Coastal Protection, Flood Control, Fresh-Air Corridors etc. Existing laws on the national, regional, local level deals with Climate Adaptation. Laws mentioned: Possibilities of spatial and urban planning should be used to reduce vulnerability of climate change.

15 Key Findings 2 German Spatial Planning Law (ROG 2 Abs.2 Nr.6 Lower Saxony law on Spatial planning and landscape planning (NROG): 2 Nr.1 Lower Saxony Spatial Planning programme Absch.1.1, Ziffer 02, Satz 3) Town Planning Code (BauGB) Guiding Principle Climate Protection ( 1 Abs. 5 BauGB), not on adaptation up to

16 Part 3: Starting Points of urban and regional planning to implement Climate Adaptation measures Urban Planning and Development Landscape Planning Planning of Flood Control Coastal Protection Planning

17 Starting Points: Urban Planning Adaptation to Urban Heat (rising Temperature maxima increasing heat periodes) Protection and establishment of green-, water-, and open spaces significant for the urban climate Guarantee ventilation of urban structures Planting and shadowing traffic areas and properties

18 Matrix: Adaptation to Urban Heat Possibilities to show and fix certain adaptation measures within local Land use plan (FNP) Town plans (B-Plan)

19 Starting Points: Urban Planning Adaptation to frequently and heavy extreme precipitation events Reducing the degree of impervious surfaces in urban areas Measures of decentralized rain water management Protection of urban areas, housing and infrastructure from impacts through heavy rainfall events

20 Starting Points: Landscape Planning Protection of free spaces for climate functions cool air development areas fresh-air corridors Adaptation on changes in the landscape water household Sustainable land-use management Spatial oriented adaptation measures of water management in lower coastal regions Improvement of the habitat nets protecting Biodiversity Establishment of a habitat net system across regions

21 Starting Points: Flood Control Technical flood control Dykes, dams, walls, Dams with retention areas Precautionary flood control Area Precaution through Water Laws (EU) Construction precaution through adapted architecture and usage Behaviour Precaution through Information and early warning systems Risk Precaution through assurance and reserve funds

22 Starting Points: Coastal Protection Defence on the existing dyke line Extra Climate Change amount on water level within Masterplan of Bremen/Lower Saxony (50cm) Area-based adaptation of the coast system (Re-) Establishment of a second dyke line Storm surges overflow polder Physical protection (building protection) Adapted use in risk areas

23 Storm surges overflow polder LROP Spatial Planning Lower Saxony 2008 From a spatial planning view, alternatives of coastal protection has to be taken into account because of Climate Change and Sea-Level Rise. Research, development and testing alternative Coastal protection strategies

25 Final Findings and... Adaptation measures may implement within existing federal and regional planning systems Powerful instruments......when used. Climate Adaptation as one of the guiding principles for future spatial planning is in the beginning Next Steps Optimizing the guide Good Practices, Checklists and other tools...
