Scottish Natural Heritage Scotland’s Greenspace Map in Action Case study 2: Climate change adaptation opportunities mapping in Glasgow and the Clyde Valley Scotland’s Greenspace Map (SGM) is a Summary Geographical Information System (GIS) based map which provides comprehensive Climate Ready Clyde is a forum for public sector, private information on the location, extent and type sector and community facing organisations to identify and discuss the challenges that Glasgow and the Clyde Valley i of greenspace across urban Scotland. faces as a result of climate change. One key action of the It was compiled from 32 individual local authority forum is the development of a Climate Change Adaptation greenspace datasets. The datasets were produced Strategy for the region.

This work is an extension of previous green network opportunities mapping analyses at a regional and local authority level. These analyses have relied heavily on data from SGM. SGM provides the key dataset for quantity, typology and distribution of greenspace. This is combined with datasets relating to public access, greenspace quality, development priorities, deprivation levels, flood risk, temperature mapping etc. allowing key locations for action to be identified.

Green Network in the GCV Strategic Development Plan area. The analysis used SGM as part of a range of Green Network, - Where are the priority areas to expand the development and social datasets to identify strategic Green Network for: locations where the planning process and the targeting of a. biodiversity habitat networks? resources can deliver multiple Green Network benefits. b. public access to greenspace? The findings from this analysis were published in the Main - Where are the major areas of land-use change Issues Report for the Glasgow and Clyde Valley Strategic (which offer chances to create new greenspaces) Development Plan (2010)iv and the subsequent Strategic and social need (where the Green Network can deliver Development Planv approved in May 2012. maximum social and health benefits)? Although originally conceived to identify strategic A series of datasets were used for opportunities opportunities across the region it was recognised from mapping at the Regional and Local Authority levels. the outset that the resultant data could also be interrogated These datasets were: at a finer resolution for more localised opportunities – not Layer 1: Existing greenspace provision, path least because many of the delivery mechanisms for the network and potential for enhancement Green Network exist at the local authority level.

Layer 3: Strategic development opportunities, To illustrate how this regional approach was used at the land-use change opportunities and areas of social local level we will examine Green Network Opportunities need Mapping for the Inverclyde Council (IC) area published by the Partnership in May 2013.vi This was developed in - Development and Regeneration Priority areas partnership with Inverclyde Council staff. - SIMD dataset In order to rank and prioritise the Green Network opportunities identified by each of the datasets, and to aid the GIS analysis, a system of weighting was applied. This allowed the analysis to prioritise: - those areas undergoing regeneration and redevelopment (where opportunities for green network action may be highest) - those spaces where quality is poorest (and quality improvements will have most effect) - those areas where greenspace improvements will have the greatest impact on network connectivity (for biodiversity and for people) - those areas where greenspace improvements will have the greatest social and health impacts (with the lowest 15% SIMD datazones being weighted high for action) Case study 2: Climate change adaptation opportunities mapping in Glasgow and the Clyde Valley Page 2 Inverclyde - Strategic Green Network Opportunities Figure 2: Areas where the greatest opportunity exists to enhance the Green Network Opportunity mapping outputs As an example, the Partnership (at the request of the Council) ran two separate analyses of data for Inverclyde – one focusing on the areas of greatest opportunity for action (using the Development and Regeneration priorities) and the other using the SIMD dataset to identify the potential for delivering social and health benefits (see Figure 2 and 3). The analysis generated two sets of priority areas and a short report on the issues and opportunities for each priority area.
