Resilience, climate adaptation and cross-sectoral partnershipbuilding in London 30 January 2015 Juliette Daniels Director, Climate UK and London Climate Change Partnership What are the key climate impacts for London? • • • • • • • • • Flooding Sea level rise and storm surge Overheating Water resources Wind storms Snow and ice Air quality Subsidence and heave Global climate events Overheating • Up to 10°C warmer than surrounding areas • Interactions with air quality – health concern • Transport and productivity issues Flooding • Over 680,000 properties at risk of surface water flooding • 15% of London in the river flood plain • TE2100 plan for tidal flood risk Drought • Area of serious water stress •In a dry year, demand currently exceeds supply. •Only 1 in 4 homes has a water meter Identifying Areas of Water Stress, EA •The Victorian-era water distribution network loses over 1/4 water in leakage Business impacts to consider London Climate Change Adaptation Strategy A risk-based approach that: 1. Assesses how London is vulnerable to weather-related risks today 2. Uses climate projections to understand how climate change accentuates existing risks or creates new risks / opportunities in the future 3. Identifies and tests risk management options Understanding the ‘adaptation gap’ Maximum water level rise: 0m 1m 2m 3m 4m Improve defences Improve Thames Barrier and raise d/s defences Over-rotate Thames Barrier and restore interim defences Flood storage, improve Thames Barrier, raise u/s & d/s defences Existing system Maximise storage Flood storage, over rotate Thames Barrier, raise u/s & d/s defences Raise Defences Flood storage, restore interim defences New Barrier New barrier, raise defences New barrage Note: Each box represents one or more portfolios of responses High ++ 2100 Defra 2100 New barrier, retain Thames Barrier, raise defences TE2100 developed options Adaptation and Resilience Opportunities – Global Adaptation Economy estimated at £1.4 trillion, forecast to grow to £2 trillion by 2025 (~3% GDP) – Strong throughout the recession and set to continue growing – Cities are more comparable with each other than with their respective countries: by working together we can grow our expertise! Government and public sector bodies Knowledge exchange Collaboration Private sector Cooperation NGOs and community sector LCCP’s Vision London’s people and systems are dynamically adapting to its changing climate, and its economy is reaping the rewards of being a world leader in this field. London Climate Change Partnership 2020 Vision Physical Economic Social Vulnerability Vulnerability Vulnerability Gathers local evidence and research to inform planning and investment - Monitors progress Examines economic weather impacts at a range of spatial scales Prioritises efforts to identify and raise the adaptive capacity of the most vulnerable groups Critical urban systems Considers the interdependencies and thresholds for supply chain disruption for London's critical services and infrastructure Comms Communicates the impacts of climate change to intermediary groups and communities through existing channels Connecting Research and sharing knowledge Informing Policy Opportunities For Growth Identifies the opportunities for London to develop and export its expertise on climate change City scale stakeholder engagement Provision of international services, insurance, finance and international. Location of international agencies. International / Company wide National influence Provision of national infrastructure and services within city. Location of national government.
