Temperature patterns that can influence conditions within dwellings, and therefore the comfort and health of occupants, are projected to shift according to the Met Office Hadley centre climate models. To illustrate these patterns, the average daily maximum temperature(°C) is mapped for the average year in the time period for the 50th and 95th percentile models out of the 12-model suite. Time periods are baseline (1980-2000), 2030 (2021-2040), and 2070 (2061-2080). County-level results represent an area-weighted-average of the results for each climate data grid within the county.

Specific humidity is a measure of the amount of moisture in the air per unit weight of dry air. Shifting patterns of specific humidity, as projected by the Met Office Hadley Centre climate models, can influence indoor air quality conditions, with consequential impacts to occupant health. To help illustrate these patterns, the average annual specific humidity (g H2O / kg dry air) is mapped for the average year in the time period for the 50th and 95th percentile models out of the 12-model suite. Time periods are baseline (1980-2000), 2030 (2021-2040), and 2070 (2061-2080). County-level results represent an area-weighted-average of the results for each climate data grid within the county.

Precipitation patterns that can influence building fabric degradation rates are projected to shift according to the Met Office Hadley Centre climate models. To help illustrate these patterns, the cumulative annual precipitation (mm) is mapped for the average year in the time period for the 50th and 95th percentile models out of the 12-model suite. Time periods are baseline (1980-2000), 2030 (2021-2040), and 2070 (2061-2080). County-level results represent an area-weighted-average of the results for each climate data grid within the county.

Relative humidity is a measure of the amount of moisture in the air presented as a percentage of the maximum amount of moisture that air can hold at its current temperature. Shifting patterns of relative humidity, as projected by the Met Office Hadley Centre climate models, can influence indoor air quality conditions, with consequential impacts to occupant health. To help illustrate these patterns, the average annual relative humidity (%) is mapped for the average year in the time period for the 50th and 95th percentile models out of the 12-model suite. Time periods are baseline (1980-2000), 2030 (2021-2040), and 2070 (2061-2080). County-level results represent an area-weighted-average of the results for each climate data grid within the county.

The Active Travel (Wales) Act 2013 places duties on local authorities and the Welsh Government with the aim to improve infrastructure and significantly increase levels of walking and cycling in Wales. The duties include that existing active travel routes must be mapped all places that have been specified (currently 142 'designated localities') and that integrated network plans must be prepared for these places. All approved existing active travel infrastructure in the designated localities – the 'Existing Routes Map' – can be found here. The maps includes routes that have achieved the statutory Design Guidance standards plus a handful of those that fall just below but are deemed important enough by the local authority to be included. Any routes that have not reached the standards are accompanied by a statement that explains their limitation(s). Each local authority is required to submit an Integrated Network Map – which shows their aspirational network of routes in their region in the next 15 years – to Welsh Ministers for consideration by 3 November 2017. These aspirational routes, once approved, will be available here. Further details on the Act, its implementation and the Design Standards can be found here.
Spatial data for Active Travel Act (Wales) 2013 Designated Localities, as a result of Direction designating localities in relation to Active Travel routes. The Welsh Ministers, in exercise of the powers conferred on them by section 2(4) and (5) of the Active Travel (Wales) Act 2013 (“the Act”), make the following Direction: Section 2(1) of the Act provides that for the purposes of the Act a route in a local authority’s area is an active travel route if:a) the route is situated in a designated locality in the area; Section 2(4) of the Act provides that, in the Act, “designated”, in relation to a locality, means specified, or of a description specified, in a direction given by the Welsh Ministers. Section 2(5) provides that the Welsh Ministers may, in particular, specify a locality, or description of a locality, by reference to:a) density of the population,b) size,c) proximity to densely-populated localities above a particular size,d) position between such localities,e) proximity to community services and facilities,f) potential for other reasons to be a locality, or a description of locality, in which more travel is undertaken by walkers and cyclists by active travel journeys.

Action to manage and improve air quality is largely driven by European (EU) legislation. The 2008 ambient air quality directive (2008/50/EC) sets legally binding limits for concentrations in outdoor air of major air pollutants that impact public health such as particulate matter (PM10 and PM2.5) and nitrogen dioxide (NO2). As well as having direct effects, these pollutants can combine in the atmosphere to form ozone, a harmful air pollutant (and potent greenhouse gas) which can be transported great distances by weather systems.
Background pollution maps at 1x1 km resolution are modelled each year under Defra's Modelling of Ambient Air Quality (MAAQ) contract. These maps are used to provide policy support for Defra and to fulfil the UK's reporting obligations to Europe. They are also made publicly available for other research applications such as university studies, epidemiology and public health research, nature and conservation studies. The models are continually updated and improved and so the methodology often changes each year. The most recent methodology report is for 2020 and can be found on the UK-AIR website: Report (PDF). Users should be mindful of these year to year changes when comparing model outputs between years. Most of the model outputs are annual means, represented in µg m-3. CO concentrations are represented in mg m-3. Specific units and information about the different metrics is provided in the summary table below.

This spatial dataset depicts the location of allotments or community growing spaces across Wales. Allotments or Community Growing Spaces are defined by Ordnance Survey as "Areas of land for growing fruit, vegetables and other plants, either in individual allotments or as a community activity. Produce is for the grower's own consumption and not primarily for commercial activity". These data have been derived from the greenspace sites geolocated polygon layer that forms part of Ordnance Survey's Open Greenspace Dataset. The allotments have been mapped by extracting the polygon centroids and creating a point dataset. The October 2022 version of OS Greenspace dataset was used to create this data set.

This dataset comprises the boundaries of Ancient Woodland sites in Wales. Each site is categorised as either Ancient Semi Natural Woodland (ASNW), Restored Ancient Woodland Site (RAWS), Plantation on Ancient Woodland Site (PAWS) or Ancient Woodland Site of Unknown Category (AWSU). Initially all woods greater than 2 ha shown on the Ordnance Survey (OS) 1:25 000 1st Series maps surveyed between 1880 and 1960 were considered. Evidence as to which of these were ancient was provided by presence on the earlier 19th century OS 1st Edition Maps (surveyed 1805 - 1873; scale 1:63 360). The general presumption was that woodland on 1800s maps was ancient, unless there was other evidence that the wood originated between 1600AD and 1800. Supportive indications of ancient status included the wood's name, its situation in the landscape, and the nature of both the surrounding pattern of enclosure and the pattern of boundaries within the wood. Where available, field survey data such as the presence of indicator species, or other historical maps and documents were also used. In mountainous areas such as Wales the first edition Ordnance Survey 1 inch maps were hard to interpret because the heavy hatching used to indicate steep slopes tended to obscure tree symbols.

This layer has been derived from the Aquaculture Resource Area, following work undertaken by ABPmer to refine the Aquaculture Resource Area to reflect technical constraints (e.g. water depth) and hard constraints (factors or activities, such as existing infrastructure, which would realistically prevent development). Welsh Government has then made further refinements to the area: to exclude areas further than 3 nautical miles from the mean high water mark; to remove areas overlapping with the Aggregates Refined Resource Area; and to remove any small, fragmented areas less than 2km2.
The Aquaculture RA was derived predominantly from a study by ABPmer (2015), ‘A Spatial Assessment of the Potential for Aquaculture in Welsh Waters’ commissioned by the Welsh Government. The project required the development of spatial data layers to highlight potential aquaculture areas based on suitable natural resources, other marine uses, and proximity to essential infrastructure. In addition to the areas identified by ABPmer this dataset includes areas identified by the Welsh Government as possible resource areas. These additional areas were identified based on local knowledge but may not be comprehensive. ************************************************************* Derivation of RAs Resource Areas (RAs) are broad areas that describe for some sectors the distribution of a particular resource that has the potential to be used or is used.

This spatial dataset contains the digital boundaries of all Areas of Outstanding Natural Beauty (AONBs) in Wales. AONBs are established under the Countryside Act of 1949, but unlike National Parks, AONBs are not created specifically for opportunities for recreation. However, recreation within AONBs is acceptable if it is consistent with the conservation and enhancement of natural beauty and the needs of agriculture, forestry and other uses.

This dataset comprises of polygons relating to each site identified under the Bathing Water Directive (76/160/EEC); however these polygons have no formal status under the Bathing Water Directive. Where a site corresponds to a Sensitive Area under the Urban Waste Water Treatment Directive (UWWTD) in England & Wales, the polygon for that Sensitive Area is provided. For all other sites the polygon has been drawn as a simple guide to aid the work of Natural Resources Wales with permitting of discharges. These polygons are not appropriate for identifying areas suitable for bathing. The polygons are not a definition of the extent of the bathing water under the Bathing Water Directives 76/160/EEC or 2006/7/EC and should not be used for any definition of the bathing water area or extent.

The Areas Benefiting from Flood Defences show areas in Wales that benefit from flood defences that protect against flooding from Rivers and the Sea. The areas shown benefit from different levels of flood protection and this is recognised in the risk classification shown in the Flood Risk Assessment Wales (FRAW) map. The outer boundary for the Areas Benefiting from Flood Defences is fixed to the Low risk flood extent for flooding from Rivers or the Sea (i.e. the area with a 0.1%, or 1 in 1,000, chance of flooding in any year). It is not property specific and shows the benefit for a general area. This information is different to the previous Flood Map: Areas Benefiting from Flood Defences which only showed the benefit provided in the event of a river flood with a 1% (1 in 100) chance of happening each year, or a flood from the sea with a 0.5% (1 in 200) chance of happening each year. Further information is available in the metadata. Attribution Statement Contains Natural Resources Wales information © Natural Resources Wales and Database Right. All rights Reserved.
