5.0PUBLIC BENEFIT MAPS –THE EVIDENCE BASEPhotograph © Nathalie HeuberMAP 27: GATEWAYS TO ECONOMIC AREASMap 27 shows the primary transport routes through the region. Areas shown in brown are nodes and gateways where certain businesslocations are optimal. The quality of GI and the environment in such areas is an influence on inward investment decisions.The Map could be further refined through local knowledge and incorporation of data on strategic sites for inward investment.41
6.0COMBINING THE EVIDENCE –TOWARDS A PUBLICBENEFIT ASSESSMENT6.0 COMBINING THE EVIDENCE –TOWARDS A PUBLIC BENEFIT ASSESSMENT6.1 Maps 1 to 27 have illustrated a range of indicators of mostrelevance to how GI might support the delivery of the EastMidlands’ Integrated Regional Strategy. It will be recognisedthat these maps are interlinked.6.2 The key to the study was to illustrate how the mass of indicatordata and maps can be combined in such a way as tohighlight those areas of the East Midlands where uplift inquantity and/or quality of GI is most critical to the region’ssustainable development.6.3 Public benefit will generally be greatest where social,economic and environmental outcomes are delivered in parallel.6.8 The use of kilometre square grids might be thought to be arather broad scale of focus, especially as many of the build-upmaps are constructed at much finer scales of analysis.However, the combination exercise, even usingsophisticatedGIS, is resource-hungry; and to map the whole region at finerscales would require more memory than was available.6.9 To overcome concerns about local hotspots of need beingobscured, the score that was used for each kilometre squarewas calculated on the basis of the highest scoring pointanywhere within that square. At a regional spatial scale, it isfelt that the results are more than adequate; although forlocal prioritisation exercises, a finer scale of mapping wouldbe desirable and feasible.COMBINED MULTIPLE BENEFITS MAP6.4 With this in mind, the single-issue evidence base shown inMaps 1 – 27 was combined to build a picture of where greatestsocial, environmental and/or economic benefit might arise.SOCIAL, ENVIRONMENTAL & ECONOMIC BENEFITS MAPS6.5 For all 27 maps, the region was broken down into 1km gridsquares. Within each of these maps, and based upon itspotential to deliver GI benefits, a score from zero to three wasassigned to each square. Scores were then totalled for eachIRS theme (social, environmental and economic).6.6 For example, as thirteen maps were generated torepresent the public benefits GI could contribute towards theIRS`s social objectives, the maximum score any square couldtotal under the social theme would be 39 (13 x 3).6.10 Because of the unequal number of indicators for eachtheme, aggregating them into a single combined public benefitsmap would disproportionately weight the theme with thehighest number of maps (in this case, the social outcomes).6.11 To avoid this, the range of scores were equalised into 10quantiles, with scores ranging from 1 - 10 (10 being the areasof greatest benefit, and 1 the lowest). The individually themedmaps were then overlaid and the score for each grid squarewas again aggregated to a maximum possible value of 30 (10x 3). In this way all the scores from across all the three themeswere aggregated, but with an equal (33.3%) weighting tosocial, economic and environmental themes.6.12 This resulted in the following suite of maps, described onthe following pages:6.7 For each of the three themes, a map is produced showingthe region in scoring “bands” relating to the potential togenerate public benefits (maps 28a – 30b).Map 28a Potential Social Benefit arising from GI DeliveryMap 28b: Potential Social Benefit arising from GI Delivery(3D visualisation)Map 29a: Potential Environmental Benefit arising fromGI DeliveryMap 29b: Potential Environmental Benefit arising fromGI Delivery (3D visualisation)Map 30a: Potential Economic Benefit arising fromGI DeliveryMap 30b: Potential Economic Benefit arising fromGI Delivery (3D visualisation)42Map 31a: Combined Multiple Benefit arising from GI DeliveryMap 31b: Combined Multiple Benefit arising from GI Delivery(3D viualisation)Map 31c: Combined Multiple Benefit arising from GI DeliveryEmphasising top 30% environmental benefits
