With increasing recognition of the importance of insects, there are growing concerns that insect biodiversity has declined globally, with serious consequences for ecosystem function and services. Yet, gaps in knowledge limit progress in understanding the magnitude and direction of change. Information about insect trends is fragmented, and time-series data are restricted and unrepresentative, both taxonomically and spatially. Moreover, causal links between insect trends and anthropogenic pressures are not well-established. It is, therefore, difficult to evaluate stories about "insectageddon", to understand the ecosystem consequences, to devise mitigation strategies, or predict future trends. To address the shortfalls, we will bring together diverse sources of information, such as meta-analyses, correlative relationships and expert judgement. GLiTRS will collate these diverse lines of evidence on how insect biodiversity has changed in response to anthropogenic pressures, how responses vary according to functional traits, over space, and across biodiversity metrics (e.g. species abundance, occupancy, richness and biomass), and how insect trends drive further changes (e.g. mediated by interaction networks). We will integrate these lines of evidence into a Threat-Response model describing trends in insect biodiversity across the globe. The model will be represented in the form of a series of probabilistic statements (a Bayesian belief network) describing relationships between insect biodiversity and anthropogenic pressures. By challenging this "Threat-Response model" to predict trends for taxa and places where high-quality time series data exist, we will identify insect groups and regions for which indirect data sources are a) sufficient for predicting recent trends, b) inadequate, or c) too uncertain. Knowledge about the predictability of threat-response relationships will allow projections - with uncertainty estimates - of how insect biodiversity has changed globally, across all major taxa, functional groups and biomes. This global perspective on recent trends will provide the basis for an exploration of the consequences of insect decline for a range of ecosystem functions and services, as well as how biodiversity and ecosystem properties might be affected by plausible scenarios of future environmental change. GLiTRS is an ambitious and innovative research program: two features are particularly ground-breaking. First, the collation of multiple forms of evidence will permit a truly global perspective on insect declines that is unachievable using conventional approaches. Second, by validating "prior knowledge" (from evidence synthesis) with recent trends, we will assess the degree to which insect declines are predictable, and at what scales.

The most abundant form of litter in the marine environment is plastic, and the negative and detrimental consequences of plastic debris on fish, reptiles, birds and mammals are well documented. The hard surface of waterborne plastic provides an ideal environment for the formation of biofilm for opportunistic microbial colonisers; however, our knowledge of how microorganisms interact with microplastics and alter the dispersal behaviour of marine plastics in the environment is a significant research gap. Biofilm at the interface between the plastic surface and the environment has been termed the 'Plastisphere', and although plastics are extremely resistant to decay, variability in composition determines their specific buoyancy and surface rugosity, which will dictate the extent of microbial colonisation and their ability for long distance dispersal. Furthermore, because plastic debris can persist in the marine environment longer than natural substrates, e.g. feathers and wood, it offers an opportunity for the wider dissemination of pathogenic and harmful microorganisms. Microplastics from clothes, cosmetics and sanitary products are now common constituents of sewage systems and they frequently bypass the screening mechanisms designed to remove larger waste items from being exported to coastal waters. Microplastics entering aquatic systems from waste water treatment plants (WWTPs) come in close contact with human faeces, hence providing significant opportunity for colonisation by faecal indicator organisms (FIOs) and a range of human bacterial pathogens. Importantly however, there have never been any studies investigating the ability of enteric viruses binding to microplastics (or binding to the biofilm on the plastic surface), and this now needs critical evaluation in order to understand this potentially novel mechanism for the environmental dispersal of enteric viruses. Furthermore, there is growing evidence that the plastisphere can promote gene exchange, and so determining the potential of plastisphere biofilms for providing the surface for anti-microbial resistance (AMR) gene transfer is of the utmost importance. There is currently a lack of fundamental understanding about the mechanisms by which microorganisms, particularly pathogenic bacteria and viruses, can "hitchhike" on microplastic particles and be transported to beaches, bathing waters, shellfish harvesting waters and high benthic diversity zones. Consequently, it is not yet possible to determine the risk from these potential pathways, or establish environmental monitoring guidelines for informing future policy or environmental regulation. Therefore, the novelty of this project is to quantify the processes that are occurring within the plastisphere, and understand the potential for the vectoring of pathogenic viruses and bacteria. Previous research on chemical co-pollutants present on plastics often fails to consider the likely impacts of plastisphere communities. Microplastics in the environment are potential vectors for these chemicals, which often desorb when ingested by marine species, and can accumulate in the food chain. Microbes in the plastisphere may either mitigate this problem through biodegradation, or enhance it by increased biofilm binding; however, most laboratory-based studies are carried out with pristine non-colonised plastics, and ignore the pivotal role the plastisphere plays on defining the risk of microplastics in the environment. By understanding the multi-pollutant and multi-scale effects of microplastics, the "Plastic Vectors Project" will help to establish a more accurate risk assessment of microplastics by taking into consideration the effects of harmful plastic-associated microbes together with chemical co-pollutants. Therefore, the "Plastic Vectors Project" aims to quantify the significance and function of microbes in the 'plastisphere', and will deliver feasible solutions for reducing these multi-pollutant risks

Over half of global gross domestic product is dependent on nature, yet the past decades have seen unprecedented damage to ecosystems and declines in biodiversity due to adverse human activities. Financial institutions (FIs) can play an important role in securing a nature-positive future. Decisions by FIs over capital allocation and risk pricing influence structural shifts in the real economy that have profound impacts on nature. Today, opportunities to align nature and capital in ways that benefit people, nature and FIs are missed because these impacts are not accounted for. Our aim is to contribute the foundational networks, upskilling of researchers and robust, standardised methods and tools needed to integrate biodiversity and nature into financial decision making. Our focus is the scenarios used by FIs to influence risk pricing and investment decisions, alongside the relevant and suitable data and tools needed for scenario analysis, such as asset-level data and tools to assess nature-related financial risks. A further novel aspect of our proposal is the on integrated nature-climate scenarios. Scenarios and analytics for use by FIs must consider biodiversity and climate in an integrated way. Biodiversity and climate are often treated in siloes, driving potential systemic risks. Important interactions and feedbacks are not accounted for, leading to underestimation of risks and critical tipping points. An important innovation in our proposal is to bring together the IPBES, IPCC and FI scenarios communities, leaders of whom are partners to this project, to address this gap. Integrating nature and climate requires new science; our proposal is to develop the networks and co-design and pilot the frameworks to achieve this - i.e. the foundational common framework and language needed to close the gap. This will create the foundation to Phase 2 that will generate the new datasets and toolkits needed. Here we particularly target scenarios and analytics for use by Central Banks and Supervisors (CB&Ss). This is because CB&Ss are important catalysts of wider action by FIs. Supervisory expectations and regulations, e.g. disclosure, capital requirements and stress-testing, set the rules by which FIs operate, while monetary policies shape the playing field, together having a major influence on global capital flows and so nature. In developing this proposal, we have consulted with the leading CB&Ss and policy makers (e.g. Defra, HMT) that are shaping this agenda and leading work on scenarios, all of whom have agreed to join the project as project partners. This includes the European Central Bank, the Banque de France, De Nederlandsche Bank, the Network of Central Banks and Supervisors (CB&Ss) for Greening the Financial System (NGFS), and the Task Force on Nature-Related Financial Disclosures (TNFD). Phase 1 of the project will deliver several important building blocks. Firstly, it will establish and operationalise the multi-disciplinary nature-climate-finance network. Secondly, it will co-develop the framework and guidance to generate the nature-climate scenarios and analytics, alongside syntheses of evidence and gap analyses. Finally, it will deliver a demonstrator application to a CB&S use case in stress testing nature-related risks. We will capture lessons learnt through this project to inform Phase 2, as well as share them to inform the development of the wider NERC Nature Positive Futures (NPF) programme. Our goal is that the network and the analytical framework developed will ultimately catalyse shifts in financial flows that reduce systemic risks and are aligned with a nature-positive future. Through consultations, we have understood the key milestones and actors to achieve this and shaped the project accordingly. We will work closely with our project partners, and link to UKCGFI, to ensure our outputs feed into the key processes, as well as collaborate with and support the wider NPF programme goals.

This world-leading Centre for Doctoral Training in Bioenergy will focus on delivering the people to realise the potential of biomass to provide secure, affordable and sustainable low carbon energy in the UK and internationally. Sustainably-sourced bioenergy has the potential to make a major contribution to low carbon pathways in the UK and globally, contributing to the UK's goal of reducing its greenhouse gas emissions by 80% by 2050 and the international mitigation target of a maximum 2 degrees Celsius temperature rise. Bioenergy can make a significant contribution to all three energy sectors: electricity, heat and transport, but faces challenges concerning technical performance, cost effectiveness, ensuring that it is sustainably produced and does not adversely impact food security and biodiversity. Bioenergy can also contribute to social and economic development in developing countries, by providing access to modern energy services and creating job opportunities both directly and in the broader economy. Many of the challenges associated with realising the potential of bioenergy have engineering and physical sciences at their core, but transcend traditional discipline boundaries within and beyond engineering. This requires an effective whole systems research training response and given the depth and breadth of the bioenergy challenge, only a CDT will deliver the necessary level of integration. Thus, the graduates from the CDT in Bioenergy will be equipped with the tools and skills to make intelligent and informed, responsible choices about the implementation of bioenergy, and the growing range of social and economic concerns. There is projected to be a large absorptive capacity for trained individuals in bioenergy, far exceeding current supply. A recent report concerning UK job creation in bioenergy sectors concluded that there "may be somewhere in the region of 35-50,000 UK jobs in bioenergy by 2020" (NNFCC report for DECC, 2012). This concerned job creation in electricity production, heat, and anaerobic digestion (AD) applications of biomass. The majority of jobs are expected to be technical, primarily in the engineering and construction sectors during the building and operation of new bioenergy facilities. To help develop and realise the potential of this sector, the CDT will build strategically on our research foundation to deliver world-class doctoral training, based around key areas: [1] Feedstocks, pre-processing and safety; [2] Conversion; [3] Utilisation, emissions and impact; [4] Sustainability and Whole systems. Theme 1 will link feedstocks to conversion options, and Themes 2 and 3 include the core underpinning science and engineering research, together with innovation and application. Theme 4 will underpin this with a thorough understanding of the whole energy system including sustainability, social, economic public and political issues, drawing on world-leading research centres at Leeds. The unique training provision proposed, together with the multidisciplinary supervisory team will ensure that students are equipped to become future leaders, and responsible innovators in the bioenergy sector.

From space, the human impact on the planet is seen by the spread of cities; but the cities themselves are spreading into much larger territories, amorphous sprawling areas between and surrounding cities - i.e. the 'peri-urban'. Arguably, the planet has not only entered the Anthropocene, but also a 'Peri-cene': a global human-environment system shaped by peri-urbanization. Around the world the peri-urban displays many characteristics: global hubs and local enclaves, sprawl and disorder, disruption of communities and livelihoods, and in particular, growing climate risks and ecological disruption. Peri-urbanisation is both a material process of land-use change and impact, and a human process of social, economic, political, and cultural transitions: whether informal or planned, intensive or extensive, the peri-urban is critical to the provision of urban food, energy and water. In turn, understanding peri-urbanisation is critical to three Sustainable Development Goals: Goal 11 on Sustainable Cities and Communities, Goal 13 on Climate Action, and Goal 15 for Life on Land. The PERI-CENE project will provide the first ever comprehensive assessment of peri-urbanisation climate impacts, risks and vulnerabilities. It will provide a global typology and global assessment with an inter-active peri-urban analysis tool. It builds an interactive Living Lab with 18 city-regions from around the world, and explores deeper issues in two case studies. The PERI-CENE then develops forward pathways to be scaleable and transferable.
