Key adaptation principles for planning UKCIP Seek opportunities to incorporate adaptation measures into new and existing developments Work in partnership with communities Incorporate flexibility to deal with changing risks Understand existing vulnerabilities to climate and identify critical thresholds Identify key climate risks using the latest climate change projections Adopt a sequential and risk-based approach to development decisions Review your strategy regularly
Key adaptation principles for planning UKCIP Do nothing this may be an appropriate response to low priority impacts or situations where climate risks are outweighed by nonclimate factors No regret options will deliver benefits that exceed their costs, whatever the extent of climate change Low regret low-cost options that have potentially large benefits in future Win-win options are ones that contribute to desired outcomes (be they environmental, social or economic), and also improve your ability to adapt to climate risks Avoid actions that will make it more difficult to cope with climate risks in the future
Adaptation planning at different spatial UKCIP scales Conurbation or catchment scale Offers opportunities for integrated approaches to adaptation covering a mix of land uses over large areas Neighbourhood scale Discrete groups of dwellings or mixed use buildings. Needs consideration of adapting the public realm and spaces between buildings Building scale Smaller developments and individual buildings. Needs consideration of design of the building, its surroundings and how it is used and managed

Needs consideration of design of the building, its surroundings and how it is used and managed
Adaptation planning at different spatial UKCIP scales Levers, influence and policies We have identified some of the physical adaptation strategies that might be deployed in response to different climatic conditions We will now consider the mechanisms available to spatial planners to encourage or require such adaptations to be implemented. Working in table groups consider the adaptation responses indicated on each slide, discuss implications for policy and DC. and suggest ways in which they could be encouraged.

Local authority responsibilities UKCIP Climate Change Act 2008 (Part 4) Adaptation Reporting Authorities (so far no planning authorities) Planning and Compulsory Purchase Act 2004 Section 39 - Sustainable Development Planning Act 2008 Section 182 - Development plan documents: climate change policies Development plan documents must (taken as a whole) include policies designed to secure that the development and use of land in the local planning authority's area contribute to the mitigation of, and adaptation to, climate change. Flood and Water Management Act 2010 Section 9 - local flood risk management strategies and co-operation
The shape of the Local Plan UKCIP in the draft NPPF Local plans should be prepared on the basis that objectively assessed development needs should be met An evidence base adequate, up-to-date and relevant evidence about economic, social and environmental characteristics and prospects take full account of relevant market and economic signals such as land prices to inform judgements about levels of demand Specifically in relation to climate change infrastructure assess the quality and capacity of transport, water, energy, telecommunications, utilities, health and social care, waste and flood defence infrastructure and ability to meet forecast demands take account of the need for nationally significant infrastructure
What the NPPF says about adaptation? UKCIP Presumption in favour of sustainable development (para 13-18) the answer to development and growth should wherever possible be yes, except where this would clearly conflict with other aspects of national policy Core planning principles (para 19) genuinely plan-led.. Encourage multiple benefits of land use for carbon storage, flood risk management and recreation Duty to co-operate (para 44-47) Public bodies to co-operate on strategic issues, which include delivering on climate change mitigation and adaptation, energy and infrastructure requirements Planning for places (pp. 42-45) Chapter on Climate Change, Flooding and Coastal Change

UKCIP GRaBS Green and Blue Space Adaptation for Urban Areas and Eco-towns to ensure existing and new mixed use urban development is adapted to the impact of climate change through improving local and regional planning policy to put in place green and blue Infrastructure; and to facilitate the much needed exchange of knowledge and experience and the actual transfer of good practice on climate change adaptation strategies to local and regional authorities across Europe 5 Key objective 1. increase partner expertise on use of green and blue infrastructure 2. identify and influence regional planning policy and delivery mechanisms for adaptation 3. develop and use a risk and vulnerabilities assessment tool 4. develop regional and local adaptation action plans including a high level policy statement 5. improve community awareness and engagement in planning process
AAP guidance UKCIP A key output is that each partner will produce an Adaptation Action Plan (AAP), which will include a High Level Policy Statement The High Level Policy Statement will address regional policies and deliver adaptation actions at the regional and local level Each Adaption Action Plan will contain a SWOT analysis, the results generated by the Climate Risk Assessment Tool and a list of actions, delivery mechanisms and measurable targets to implement green and blue infrastructure
GRaBS Mapping Tool UKCIP Used for e.g.: AAP development, community engagement events, mapping vulnerable groups and infrastructure The User Guidance takes users through three story-lines: The first storyline is based on the risk of river flooding to people in a local authority The second storyline helps to assess social infrastructure for a regional authority The third storyline helps assess the risk of high temperatures to people in a local area http://www.grabs-eu.org/assessment.php

Adaptation Action Planning Cycle UKCIP
Stage 1: Baseline review Do we have the right evidence? UKCIP A description of the area to which the AAP relates. A description of climate change impacts projected to affect the area. Identification of vulnerable elements (communities, health and mobility issues, infrastructure, etc.) particularly at risk from climate change impacts. Organisational strengths and weaknesses related to the development of climate change adaptation responses such as knowledge, responsibility and capacity. External opportunities and threats relevant to the partner producing a climate change AAP. Identification of existing organisational and policy conditions and capacity.
Stage 2: UKCIP Explore opportunities & constraints Building adaptive capacity : Policy measures Operational measures Can we get the communities buy-in? Communities that ignore the challenge will find the cost of impacts and of insurance rising sharply, threatening their economic and social fabric. Delivering adaptation action: design and development measures that can be implemented in practice TCPA, Adaptation by design guide
Stage 3: Agree aims and objective UKCIP Can we get the right policies? Proactive and positive policies: Local planning authorities should set out how new development should be planned to avoid significant vulnerability to impacts arising from changes in the climate, Good site selection at the planmaking stage is critical Clear message that new development should be low-carbon development and well adapted to the impacts of climate change
