Use of soil erosion and soil quality research to inform development of DEFRA (Department for Environment Food and Rural Affairs) and international agricultural land management policy

Summary of the impact

Geography at Exeter has a well-established reputation for research on the effects of soil erosion and land management on soil quality, diffuse pollution, and on water quality in UK river systems. Since 2008, this research has been used to inform DEFRA policy, in relation to soils, water, and the DEFRA code of good agricultural practice. Dissemination of effective approaches to land management, most especially through the Catchment Sensitive Farming Initiative has resulted in clearly demonstrable changes in farming practice by landowners in several priority river catchments within the UK, demonstrating a positive change in behaviour and improved management of environmental risk. In addition, research on agricultural erosion has been used in the development of new agricultural policy practices in Canada.

Wildfire threat to water resources: informing catchment management policy and practice

Summary of the impact

Under future climates, wildfire will exacerbate threats to water security. Our research demonstrates that burning of surface vegetation can invigorate hillslope hydrological response with marked increases in sediment and nutrient delivery to river networks and reservoirs. Negative water quality effects include high turbidity, toxic algal blooms and fish kills with implications for water supply at critical times in the water year. Through quantifying post-fire runoff and nutrient yield processes, the research has informed (i) catchment management decisions, policies and water resource risk assessment in Australia and (ii) water industry resource protection plans in the UK.

Sustainable Urban Drainage Systems (SUDS)

Summary of the impact

Research and knowledge exchange led by Prof. Jefferies in sustainable urban drainage systems (SUDS) has driven the design and integration of SUDS into urban environments, into urban planning and everyday practice in the UK, Europe and worldwide. This research has contributed to the development of policies and established guidelines that have informed the set-up of operational and monitoring systems and the reduction of a training manual which is impacting widely on the sector (downloaded >40.000 times). Evidence gathered through this research has supported drainage policy nationally and now underpins important parts of urban infrastructure, improving environments and their resilience to flooding.

Bridging the gap between policy and regulation: new assessment tools for implementing the EU Water Framework Directive

Summary of the impact

Research by Rowan and ERG colleagues Black, Bragg, Cutler, Duck has addressed the science and policy challenges faced by statutory authorities meeting their duty to implement the EU Water Framework Directive (WFD) 2000. Assessing the sensitivity of aquatic systems to physical, chemical and biological pressures is the central theme, and through a series of commissioned projects funded by UK environment and conservation agencies, the research has:

  • Developed new assessment tools used by statutory regulators to characterise the degree of flow alteration and physical modification to rivers and lakes;
  • Developed the lake habitat survey (LHS) method, complete with accreditation programme, incorporated as best-practice in a CEN European Guidance Standard;
  • Been translated directly into legally-binding and currently used environmental standards across the UK and Ireland (through new enabling legislation);
  • Informed regulatory practices across Europe, particularly in Italy, Poland, France, Norway, Serbia and Montenegro.

Changing perspectives and policies in urban drainage practice

Summary of the impact

For over 40 years, the Urban Pollution Research Centre has undertaken pioneering work in understanding the sources, behaviour and fate of urban diffuse pollution and its mitigation using sustainable urban drainage systems (SUDS). Relevant impacts claimed here include the adoption of SUDS into UK practice and legislation, the role of SUDS as key components in achieving EU Water Framework Directive (WFD) requirements and the embedding of our research within national best practice guidelines. In response to recent policy drivers, we are collaborating with Arup to commercialise SUDSloc and are informing policy developments in the fields of diffuse pollution mitigation and urban ecosystem services.

Research for the Environment Agency to counter EU infraction proceedings against the UK Government relating to the alleged eutrophication of estuaries including the Humber

Summary of the impact

In 2008-2009 the UK was subject to legal infraction proceedings at the European Court of Justice (ECJ) for allegedly failing to implement the European Union's Urban Waste-water Treatment Directive (UWWTD). Research by the Institute of Estuarine and Coastal Studies, Hull (IECS) for the Environment Agency (EA)/Defra provided evidence to the UK Government for its defence against these allegations. The research consisted of:

- literature/data reviews and collection and analysis of critical evidence from the Humber.

- co-ordinating workshops and convening an expert panel of sufficient authoritative academic opinion to counteract the European Court of Justice allegations.

In December 2009 the European Court of Justice ruled in favour of the UK. Our research therefore helped to save very significant, unnecessary capital investment in nutrient removal technology for sewage treatment nationally and in the Yorkshire and Humber region especially. The UK government thus avoided the possibility of major European Commission fines of up to €703,000 per day, or €256m per annum, for infraction of the Urban Water-water Treatment Directive [1].

Assessment, restoration and management of urban rivers

Summary of the impact

Angela Gurnell's research on the geomorphology, hydrology and plant ecology of urban water courses has led to the development of important new tools for the biophysical assessment and improved management of urban rivers. Known as the Urban River Survey (URS), these tools are accessed by the Environment Agency and River Trusts across London, and their application is supported with workshops and guidance provided by Gurnell and her team. The URS has been used to deliver morphological quality indicators for rivers across London; to appraise river restoration schemes; to develop catchment management plans; and to assess long-term changes in rivers. It is currently being developed to quantify and set targets for river improvement schemes in relation to their impact on river ecosystem services. Gurnell's work has made a distinct contribution to urban river improvements in Britain and Europe, particularly through her leadership in developing a European framework for assessing hydromorphology.

Case 6 - Improving national surface water quality using an urban non-point pollution model and supporting database

Summary of the impact

Surface water runoff in urban areas makes a significant contribution to pollution of lakes and rivers, but historically is poorly addressed in catchment models. The School of Geography (SoG) developed a Geographic Information System (GIS) model and supporting database to quantify urban source area loadings of 18 common and priority pollutants. This knowledge improves catchment models and supports impact assessment and mitigation planning by environment managers. The research has been exploited on behalf of the Department for Energy, Food and Rural Affairs (DEFRA), the Welsh Assembly, and the UK water industry (UK Water Industry Research — UKWIR, and United Utilities). The research has had three distinct impacts: 1) its use addressing EU Water Framework Directive obligations; 2) its on-going influence on construction industry guidance; and 3) the commercialisation of its stormwater pollutant coefficient database for Sustainable Urban Drainage Systems (SUDS) planning software.

Developing modelling tools to support integrated catchment management

Summary of the impact

The intensification of food production, fossil fuel combustion and water consumption has led to substantial increases in the amount of nitrogen and phosphorus flushed from land to water. The accumulation of these nutrients in freshwaters, estuaries and the coastal zone has led to reductions in biodiversity, the loss of ecosystem services, and compromised water security. The UK is a signatory to a raft of international conventions and policies which require reductions in the flux of nutrients from land to the water and restoration of ecosystem health and services. To meet these obligations, policymakers need information on the scale of the problem, the sources of nutrients and the effectiveness of intervention measures.

Research in the Unit has directly addressed this need. It has provided robust scientific evidence of the scale of the problem and the sources of nutrient enrichment, and has provided the capability to test intervention and policy scenarios at field to national scales. It has fed directly into the development of monitoring approaches and mitigation measures now in use by the Environment Agency (EA) and Defra, informed the development of UK Government policy in relation to catchment management, and supported compliance with the EU Water Framework Directive, the renegotiation of the Gothenburg Protocol under the International Convention on Long-Range Transboundary Air Pollution, and reporting on discharges of nutrient pollution to the North East Atlantic under the OSPAR Convention.

Computer Based Methods for Diagnosing and Predicting River Health

Summary of the impact

Good quality water is essential for life on earth. The `Centre for Intelligent Environmental Systems' (CIES) has developed computer-based solutions for the assessment of river water quality by environmental agencies, working to improve the quality. CIES research has informed discussions and decisions of the UK Technical Advisory Group for the Water Framework Directive (UKTAG WFD). UKTAG WFD have selected the WHPT (Walley, Hawkes, Paisley & Trigg) method, for assessing river water quality throughout the UK, in the context of river management to meet the targets set in the Water Framework Directive (Directive 2000/60/EC from the European Union), which the UK government signed up to in 2000 (Beneficiaries: UKTAG WFD; Environment agencies; The public). Indirect impacts can also be attributed to CIES research, as it enables improvements of river quality, which triggers positive impacts on the natural environment, public health and quality of life (Beneficiaries: The public). CIES software has also been released to environment agency biologists as second opinion tools, thereby resulting in improved delivery of the public service provided by these biologists, when they use the software (Beneficiaries: Environment agencies; Environment agency biologists; The public).
