Targeted management of the UK's fire prone landscapes will be crucial in enabling the country to achieve its commitments both to reach net zero by 2050 and to halt species decline by 2030. Many of our fire prone landscapes represent nationally significant carbon (C) stores. They also provide key habitats for unique species including many on the UK BAP Priority Species listing and are of strategic conservation value. But these typically shrub and grass dominated ecosystems are threatened both by the changing UK wildfire regime and some management tools aimed to mitigate this risk. Critical trade-offs therefore exist between the impact of episodic severe wildfire events and ongoing long term management practises, as well as between the positive and negative impacts of management tools on different prioritised ecosystem services; notably between C storage, habitat management and biodiversity provision. These trade-offs and the associated best management practises will vary between landscapes that have different management history, vegetation composition, legacy soil C stores and natural environmental conditions. Thus selection of the appropriate land management from the diverse toolkit available needs to be very carefully considered; the right tool to address the right priorities at the right location. The evidence base to make this complex choice, however, is currently weak. This undermines the ability of decision makers locally and nationally to assess the consequences of different wildfire management tools. IDEAL UK FIRE will address this urgent need, by determining the environmental costs and benefits of widely applied fuel management tools (burning, cutting, rewetting and managed succession) on habitat quality, biodiversity and the carbon balance in fire prone UK landscapes. We will directly contrast those medium-/long-term responses against the initial impact of the fuel management interventions and potential wildfires of varying severity. Through i) observations and collation of extensive historical monitoring, ii) experimental burns and wider management intervention and iii) the adaptation and application of the JULES land surface model, FlamMap fire analysis system and the Rangeshifter eco-evolutionary modelling platform, the project will: - Quantify carbon consumption and charcoal production across a range of (wild)fire and management intensities in different landscapes and under different land management strategies. - Determine the medium-term trajectories of biodiversity and carbon balance post intervention through a national chronosequence of management tools. - Develop next generation models to simulate the national long-term consequences of land management strategies to the UK ecosystem carbon balance, carbon climate feedbacks, habitat quality and biodiversity. We embed all this knowledge into a newly developed accredited training module for the land management sector. The module supports land managers to understand the consequences of different management tools, supporting them to make informed decisions in their landscapes to best meet both national and local management goals. The training programme will provide a generalisable frame-work to evaluate land management practices and a knowledge platform to inform government policy on the costs and benefits of wildfire management tools.

One of the greatest challenges facing civil engineers in the 21st century is the stewardship of ageing infrastructure. Nowhere is this more apparent than in the networks of tunnels, pipelines and bridges that lie beneath and above the major cities around the world. Much of this infrastructure was constructed more than half a century ago and there is widespread evidence of its deterioration. Tunnels, particularly old ones, are prone to being influenced by activities such as adjacent construction, for instance piling, deep excavations and other tunnel construction. Excessive leakage and pipe bursts are frequent and usually unanticipated. Importantly, underground structures often cannot be inspected when they are being used by trains or due to other physical constraints. The fragility of old infrastructure also presents a challenge for new construction in congested urban environments. Little is known of the long-term performance of such infrastructure. These uncertainties and the importance of safety to users and consumers prompted the initiation of recent research projects investigating the prospect of damage detection and decision making and the use of novel materials to mitigate damage. Advances in the development of innovative sensors such as fibre optic sensors and micro electrical mechanical sensors (MEMS) offer intriguing possibilities that can radically alter the paradigms underlying existing methods of condition assessment and monitoring. Future monitoring systems will undoubtedly comprise Wireless Sensor Networks (WSN) and will be designed around the capabilities of autonomous nodes. Each node in the network will integrate specific sensing capabilities with communication, data processing and power supply. It is therefore the objective of this proposal to demonstrate how large numbers of sensors can be integrated into large-scale engineering systems to improve performance and extend the lifetime of infrastructure, while continuously evaluating and managing uncertainties and risks. This proposal is a joint project between the University of Cambridge and Imperial College London and comprises an integrated research program to evaluate and develop prototype WSN systems. The main objectives of this proposal are to bridge advances in modelling large-scale engineering infrastructure with advances in wireless sensor networks and to develop a low-cost smart sensing environment for monitoring ageing public infrastructure. Three application domains will be studied in detail: (i) monitoring water supply and sewer systems and (ii) monitoring tunnels and (iii) monitoring bridges. The complexity of the monitoring system requires the following research areas to be explored : sensor systems, wireless communications, autonomous systems, information management, programming and design tools, trust security and privacy, systems theory, human factors and social issues. Field trials will be carried out with London Underground Ltd., Thames Water, Highways Agency and Humber Bridge. Intel Corporation will support the project with hardware for the trials.

The water industry is the fourth most energy intensive secotr in the UK and uses approximately 2 -3 % of net UK electricity releasing approximately four million tonnes of green house gas emissions (carbon dioxide equivalent) every year. The industry is making progress to produce more renewable energy from its waste biomass sources. However, only 493 GWh was generated by water utilities in the UK in 2005/06 about 6.4 % of its actual requirements. The government has called for research into potentially more efficient energy generation technologies from biomass which would contribute significantly to the UK's policy objectives of 10% of electricity supply from renewable energy by 2010 and for the reduction of greenhouse gas emissions. Innovative research into low carbon treatment and production and storage and use of biogas in the water sector has the potential to offer step-change benefits to the UK's energy system. This project seeks to secure a paradigm shift in wastewater treatment and biogas application. A pilot scale feasibility study is proposed to examine: (1) the fundamental operation of an anaerobic bioreactor using fortified influent wastewater; and (2) increasing the energy-production capacity of the generated renewable biogas. This approach significantly alters the wastewater treatment flow-sheet by reducing dependence on the energy intensive activated sludge process. The project has the potential for UK energy savings of 0.12 kWh per cubic metre of wastewater treated. Over 1 million cubic metres of wastewater are treated every day which potentially corresponds to savings of 438GWh per year and 188,469 tonnes of carbon dioxide per year. This is approximately equivalent to off setting 122,000 people flying London to New York return. Potentially fortified anaerobic treatment will also yield >10 % more biogas than is currently available from anaerobic digesters. Therefore, it is important to increase its energy production capacity in line with government developments for local energy and increased energy security. Currently biogas is used in combined heat and power in the UK water sector but biogas use in fuel cells, as a transport gas and for gas supply could provide greater flexibility and efficiency with more storage opportunities. However, these applications require biogas to be upgraded. This project seeks to examine in-situ methane enrichment to provide a better economy of scale for upgrading biogas and thereby maximising the overall energy production capacity of wastewater carbon. This project will therefore help to provide the 'scientific advance and industrial innovation to utilise biomass to meet the increasing demands for sustainable products from renewable sources' called for by the government.

Globally, one in four cities is facing water stress, and the projected demand for water in 2050 is set to increase by 55%. These are significant and difficult problems to overcome, however this also provides huge opportunity for us to reconsider how our water systems are built, operated and governed. Placing an inspirational student experience at the centre of our delivery model, the Water Resilience for Infrastructure and Cities (WRIC) Centre for Doctoral Training (CDT) will nurture a new generation of research leaders to provide the multi-disciplinary, disruptive thinking to enhance the resilience of new and existing water infrastructure. In this context the WRIC CDT will seek to improve the resilience of water infrastructure which conveys and treats water and wastewater as well as the impacts of water on other infrastructure systems which provide vital public services in urban environments. The need for the CDT is simple: Water infrastructure is fundamental to our society and economy in providing benefit from water as a vital resource and in managing risks from water hazards, such as wastewater, floods, droughts, and environmental pollution. Recent water infrastructure failures caused by climate change have provided strong reminders of our need to manage these assets against the forces of nature. The need for resilient water systems has never been greater and more recognised in the context of our industrial infrastructure networks and facilities for water supply, wastewater treatment and urban drainage. Similarly, safeguarding critical infrastructure in key sectors such as transport, energy and waste from the impacts of water has never been more important. Combined, resilience in these systems is vitally important for public health and safety. Industry, regulators and government all recognise the huge skills gap. Therefore there is an imperative need for highly skilled graduates who can transcend disciplines and deliver innovative solutions to contemporary water infrastructure challenges. Centred around unique and world leading water infrastructure facilities, and building on an internationally renowned research consortium (Cranfield University, The University of Sheffield and Newcastle University), this CDT will produce scientists and engineers to deliver the innovative and disruptive thinking for a resilient water infrastructure future. This will be achieved through delivery of an inspirational and relevant and end user-led training programme for researchers. The CDT will be delivered in cohorts, with deeply embedded horizontal and vertical training and integration within, and between, cohorts to provide a common learning and skills development environment. Enhanced training will be spread across the consortium, using integrated delivery, bespoke training and giving students a set of unique experiences and skills. Our partners are drawn from a range of leading sector and professional organisations and have been selected to provide targeted contributions and added value to the CDT. Together we have worked with our project partners to co-create the strategic vision for WRIC, particularly with respect to the training needs and challenges to be addressed for development of resilience engineers. Their commitment is evidenced by significant financial backing with direct (>£2.4million) and indirect (>£1.6million) monetary contributions, agreement to sit on advisory boards, access to facilities and data, and contributions on our taught programme.
