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

Since December 1997 each local authority in the UK has been carrying out a review and assessment of air quality in their area. This involves measuring air pollution and trying to predict how it will change in the next few years. The aim of the review is to make sure that the national air quality objectives (PDF) will be achieved throughout the UK by the relevant deadlines. These

Natural Resources Wales monitors bathing water sites identified under EC Bathing Waters Directive 2006/7/EC in Wales. Samples are taken throughout the bathing season from May to the end of September and analysed for two parameters: Escherichia coli and intestinal enterococci. A classification of bathing water quality, generally based on 4 years of sample results, is produced for each bathing

The Better Woodlands for Wales (BWW) grant scheme ran from 2006 until the introduction of the Glastir Woodland Creation Grant scheme in 2010/11. BWW provided aid to land managers to achieve forest policy objectives, including the creation of new woodlands, and management of existing woodlands to secure a range of beneficial environmental and social amenity outcomes.

Boundaries of Conservation Areas in Wales, to conform with s.70(5) of the Planning (Listed Buildings and Conservation Areas) Act 1990.  This dataset provides information on the map boundaries only. For the full information, including information on designations, individuals should contact the appropriate Local Authority.

Site hosted by the copernicus programme and allows the user to view earth observation generated High Resolution Layers for 5 key land uses. Pan-European High Resolution Layers (HRL) provide information on specific land cover characteristics, and are complementary to land cover / land use mapping such as in the Corine land cover (CLC) datasets.

The guidance is to promote better understanding of the agricultural issues that affect the restoration of mineral and waste sites where the long-term agricultural potential of the land is to be preserved.

The Development Advice Map (DAM) shows areas at risk of flooding for the purposes of land-use planning. The DAM should be used alongside Planning Policy Wales and Technical Advice Note (TAN) 15 to guide new development away from areas at risk of flooding wherever possible. Together, they form a precautionary framework to guide planning decisions. The maps shown here are not designed for
