Wetland environments are amongst the most dynamic landscape types in Europe, experiencing change from climatic, demographic, economic and political influences. They have also been an area of human utilisation and exploitation for millennia, resulting in an incredible richness and diversity of tangible and intangible heritage. Wetlands across Europe, and around the world, are actively undergoing rapid change and development, but there are no tailor-made or proactive studies to identify the impacts of change on the heritage contained within wetlands. The proposed project focusses on key wetland environments in Ireland, the Netherlands and the United Kingdom to act as test cases for the identification of active and passive changes in those regions, and to identify ways in which the heritage of wetlands can contribute to contemporary social challenges. Through a combination of ethnographic survey, literature review, map regression analysis, remote survey and public and stakeholder interaction, the research will identify changing perceptions of wetland heritage, changing attitudes towards wetland utilization, and changing physical conditions within the environments which may influence the longer term survival of wetland heritage. Recent years have seen the potential role of wetlands as valuable ecoservices systems in terms of water management, flood alleviation, and carbon sequestration. This drive can often occur in direct conflict with local populace perceptions of heritage and access to wetland resources. Negotiating and reconciling the rights and perceptions of the local, national and international populace is one of the key aspects that will be addressed within the proposed research programme.

Natural flood risk management (NFM) describes methods of modifying hillslope and catchment runoff through the modification of landscapes to restore natural hydrological behaviour which limits downstream flood risk. This proposal is for a focussed study of NFM benefits associated with wider ecosystem restoration work which is under way across the uplands of the UK. Headwaters comprise 60-80% of the length of most river systems and high slopes and high rainfall mean that they are important areas of hillslope runoff production. Across the UK there are communities which are prone to flash flooding from steep upland catchments. These headwater catchments are relatively small catchments and are areas where extensive upland restoration is occurring and so they are locations where positive impacts of NFM measures are likely to be observed. Vulnerable communities in headwaters are often small and dispersed with land values that rarely justify hard engineering flood defences through standard cost-benefit approaches. If relatively low cost upland restoration approaches can mitigate risk to communities such as this then it will be possible to provide some protection to communities where funding precludes hard engineering approaches. This project will work with project partners Moors for the Future and Greater Manchester, Merseyside and Cheshire Environment Agency who have existing funded NFM work in the southern Pennines to undertake a series of field experiments. These will assess the potential impact of various forms of gully blocking, restoration of Sphagnum cover on moorlands, and establishment of upland woodlands on hillslope runoff production and channel flow. It will also assess the longer term evolution of woodland and gully blocking approaches through the study of mature woodland and well established gully blocked systems. This is an important consideration since investment in NFM works requires confidence in the long term impact of the restoration on runoff and knowledge of any ongoing maintenance costs for the interventions. Installation of NFM schemes to mitigate flood risk requires careful planning and prediction of potential impacts. This project will develop conceptually sophisticated but computationally simple models which can run multiple scenarios in order to assess the catchment wide impacts on runoff of NFM measures implemented to a variety of designs and in a variety of spatial configurations. The model will be developed (with input from project partner CH2M and input from potential users such as EA) and validated using data from the Glossop Brook catchment in Derbyshire which has a history of major flash flooding impacting households in the town of Glossop. The modelling approach will then be used to assess possible NFM interventions in the upland catchments draining to 21 communities at risk on the eastern edge of Greater Manchester. In each of these catchments we will model the optimum configuration of upland restoration measures for NFM benefit. The project will also work with partners (Environment Agency, Natural Resources Wales, Scottish Environmental Protection Agency, International Union the Conservation for Nature) to identify existing headwater flow records across the UK which relate to areas of significant upland restoration. At these sites we will model expected impacts and interrogate the available flow data for evidence of these effects on runoff. The project will work with its range of project partners which span England, Wales and Scotland and which comprise regulators, land managers and industry to develop guidelines to optimise future implementation of NFM measures in headwater catchments across upland Britain.

The Yorkshire Ouse basin, which encompasses the cities of Leeds, York and Sheffield as well as the rivers Aire, Calder, Derwent, Don, Swale, Wharfe, Ure and Nidd is home to 6.7% of the UK population, 30% of the Northern Powerhouse region and includes 10 metropolitan boroughs. The region includes a variety of different environments, from large urban areas to lowland agriculture and sparsely populated uplands including National Parks and Areas of Outstanding Natural Beauty. As such, it is a perfect location to instigate a programme of work which uses existing NERC-funded science to identify, develop, test and improve integrated solutions on a range of environmental impacts. This encompasses mitigation of drought and flood risk through improved connectivity between weather forecasting, land management and water resource management; improvements in water quality for both human water supply and rivers/other water bodies; and better management of soils for improved regional food security and carbon storage (in woodlands and peatland). By integrating these aspects of weather, land and water, it will enable better plans to be made for the region that allow for sustainable development as the population grows whilst protecting the valuable natural environment. Ultimately, by creating a region that is better able to deal with a more variable climate, it will become an area that attracts investment as people and their businesses opt to live and work in an area that has adapted to the severe effects of environmental change, with improved quality of life. Many major global companies already have their water headquarters or global environmental head offices in the region together with a range of SMEs and large businesses whose interests include catchment management. As such, there is considerable momentum behind the Yorkshire Integrated Catchment Solutions Programme - Yorkshire iCASP - which seeks to deliver economic and social impacts to the region. Yorkshire iCASP will capitalise on existing NERC-funded science to develop tools, strategies, plans and policies to promote hazard resilience, mitigation of extreme events (floods and droughts), develop flood forecasting capability, improve water quality, enhance soils and farm practice and develop a joined-up approach for land and water management. iCASP has been co-created by partners drawn from local authorities, government agencies, major infrastructure/utility owners, private sector service providers, academic institutions, and third sector organisations who will work together to produce and deliver a work programme that seeks to enhance the economic and societal status of the region. Outcomes from the collaboration will deliver tools and techniques with applicability outside the region, creating services and products which can be used around the world to further benefit the region and the UK economy more generally. Examples of the projects that have been discussed in the work programme include development of green financing enterprises; development of new tools to better link flood forecasting with impacts on rivers and different land management practices; decision-support tools that allow different area-specific flood/drought management scenarios to be evaluated; and raw water management approaches that reduce the cost of water treatment. All will have different, and often multifaceted, impacts on society and the wider environment so another important aspect of iCASP is the documentation and evaluation of the projects implemented as part of the work programme, measuring the changes that they contribute to the regional, and national, economy as well as the growth of iCASP partners through leveraged investment, job creation and wider societal benefits.

The UK is committed to quantifying and managing its emissions of greenhouse gases (GHG, i.e. CO2, CH4, N2O) to reduce the threat of dangerous climate change. Sinks and sources of GHGs vary in space and time across the UK because of the landscape's mosaic of managed and semi-natural ecosystems, and the varying temporal sensitivities of each GHG's emissions to meteorology and management. Understanding spatio-temporal patterns of biogenic GHG emissions will lead to improvements in flux estimates, allow creation of inventories with greater sensitivity to management and climate, and advance the modelling of feedbacks between climate, land use and GHG emissions. Addressing Deliverable C of the NERC Greenhouse Gas Emissions and Feedbacks Research Programme, we will use extensive existing UK field data on GHG emissions, supplemented with targeted new measurements at a range of scales, to build accurate GHG inventories and improve the capabilities of two land surface models (LSMs) to estimate GHG emissions. Our measurements will underpin state-of-the-art temporal and spatial upscaling frameworks. The temporal framework will evaluate diurnal, seasonal and inter-annual variation in emissions of CO2, CH4 and N2O over dominant UK land-covers, resolving management interventions such as ploughing, fertilizing and harvesting, and the effects of weather and climate variability. The spatial framework will evaluate landscape heterogeneity at patch (m), field (ha) and landscape (km2) scales, in two campaigns combining chambers, tower and airborne flux measurements in arable croplands of eastern England, and grazing and forest landscapes of northern Britain. For modelling, we will update two LSMs - JULES and CTESSEL- so that each generates estimates of CO2, CH4 and N2O fluxes from managed landscapes. The models will be updated to include the capabilities to represent changes in land use over time, to represent changes in land management over time (crop sowing, fertilizing, harvesting, ploughing etc), and the capacity to simulate forest rotations. With these changes in place, we will determine parameterisations for dominant UK land-covers and management interventions, using our spatio-temporal data. The work is organized in five science work-packages (WP). WP1: Data assembly and preliminary analysis. We will create a database of GHG flux data and ancillary data for major UK landcovers/landuses in order to calibrate and evaluate the LSMs' capabilities, and generate spatial databases of environmental and management drivers for the models. WP2. GHG measurement at multiple scales. We will deploy advanced technology to generate new information on spatial GHG processes from simultaneous measurement from chamber (<1 m) to landscape (40 km) length scales, and on temporal flux variation from minutes to years. WP3. Earth observation (EO) to support upscaling. EO data will provide: i) driving data for LSM upscaling, from flux tower to aircraft campaign scales; and ii) spatial data for testing LSM outputs at these larger scales. WP4 Upscaling GHG processes. Firstly, the two LSMs will be updated to allow the impacts of management activities on GHG emissions to be simulated, with calibration against an array of temporal flux data. Then, we will use the LSMs to model the fluxes of GHGs at larger spatial scales, based on a rigorous understanding of how the nonlinearity of responses and the non-Gaussian distribution of environmental input variables interact, for each GHG, using all available field data at finer scales. WP5 Application at the regional scale. The LSMs will upscale GHG emissions for both campaign regions (E. England, N. Britain) using 1-km2 resolution simulations with a focus on the airborne campaign periods of 4 weeks. We will determine how regional upscaling error can be reduced with intensive spatial soil and land management data.
