A systematic review of adaption to climate change impacts in the aviation sector

The incremental changes and greater extremes of a changing climate will have operational, infrastructure and economic impacts for aviation. Given the criticality of aviation for global connectivity and mobility, it is vital that the sector understands and adequately adapts to these risks. This article presents a systematic review of the growing but somewhat dispersed academic literature on climate change impacts and adaptation in the aviation sector. Information was synthesised from 131 studies (published between January 2000 and November 2022) on eleven climate change effects and the associated impacts and potential adaptation measures. Six areas for action to address knowledge, awareness and implementation gaps were identified: (i) to broaden geographical coverage, particularly to address the current lack of studies addressing climate risks and responses in Central and South America, Africa and the Middle East; (ii) to extend knowledge of physical impacts; (iii) to address known-unknowns such as the risks associated with unprecedented or compound extreme events; (iv) to extend knowledge of adaptation including cost–benefit analysis and consideration of integrated mitigation and adaptation; (v) to identify and apply other relevant research; and (vi) for sector bodies to support and facilitate collaboration between researchers and practitioners to co-develop accessible user-oriented climate adaptation services

Recovery and utilisation of municipal solid waste incineration bottom ash: implications for European waste management strategy

Over the last two decades, the stated intent of European waste management strategy has evolved from a specific focus on landfill diversion to enabling the transition to a circular economy. Widespread introduction of source-segregation alongside deploy-ment of material recovery technologies have improved MSW management practices across Europe. However, with diminishing returns it has become more difficult to achieve further landfill diversion through increased recycling alone, and incineration rates (across the EU-27 as a whole) have continued to increase. The advantages of incineration include the ability to harness the energy content of the waste alongside a sizeable reduction in mass and volume. However, the remaining solid residues, the most substantial being incinerator bottom ash, present a management issue. Exploring the role of incineration and the utilisation of incineration bottom ash, this paper highlights the potential risks of lock-in in the context of evolving waste poli-cy. A simple thought experiment suggests that while increased use of incineration may help member states achieve 2035 landfill diversion targets, it would also carry a substantive risk of placing the 2035 recycling target out of reach. To address this, a long-term vision concerning the future of incineration is required, where it is recom-mended that policy which focuses on landfill diversion and the recycling of residual wastes should be strengthened through mechanisms that gradually phase out incineration and distinguish between open and closed-loop recycling

Not all brownfields are equal: a typological assessment reveals hidden green space in the city

While the role of urban green space in mitigating environmental hazards and enhancing urban resilience is widely recognised, the current or potential contribution of brownfield land to urban green infrastructure and ecosystem services has been largely overlooked by planning legislation. The perception of brownfield as low value spaces has instead driven a focus on brownfield-first redevelopment, and thus, this dynamic resource is quickly being lost. This research, based on GIS and remote sensing data, develops a novel hierarchical brownfield classification methodology to understand the nature and distribution of brownfield, using k-means clustering of several physical attributes, which can be used for a range of objectives and is widely applicable to post-industrial cities. Application of the methodology to the case study, Greater Manchester, UK, produced a typology of twenty-six brownfield types with distinct characteristics and differing spatial patterns across the city. Land cover analysis reveals that over half (51%) of brownfield land is vegetated (comprising 27% trees and shrubs, 24% grass and herbaceous vegetation), highlighting the significant ‘hidden’ green space present on brownfield. Brownfield sites traditionally perceived as difficult to develop (e.g. those with uneven topography, irregular shapes, or a water body), are particularly highly vegetated. Predominantly pervious types are widely distributed across the conurbation, including in built-up areas, which are a principal target for redevelopment, and thus highly vegetated brownfields are likely being lost undetected. Brownfield land is evidently a valuable dynamic resource in post-industrial cities and redevelopment should be planned at the city-scale to ensure careful strategic selection of sites for redevelopment, greening, or interim use based upon their characteristics and location

How do we evaluate the cost of nosocomial infection? The ECONI protocol: an incidence study with nested case-control evaluating cost and quality of life

Introduction Healthcare-associated or nosocomial infection (HAI) is distressing to patients and costly for the National Health Service (NHS). With increasing pressure to demonstrate cost-effectiveness of interventions to control HAI and notwithstanding the risk from antimicrobial-resistant infections, there is a need to understand the incidence rates of HAI and costs incurred by the health system and for patients themselves. Methods and analysis The Evaluation of Cost of Nosocomial Infection study (ECONI) is an observational incidence survey with record linkage and a nested case-control study that will include postdischarge longitudinal follow-up and qualitative interviews. ECONI will be conducted in one large teaching hospital and one district general hospital in NHS Scotland. The case mix of these hospitals reflects the majority of overnight admissions within Scotland. An incidence survey will record all HAI cases using standard case definitions. Subsequent linkage to routine data sets will provide information on an admission cohort which will be grouped into HAI and non-HAI cases. The case-control study will recruit eligible patients who develop HAI and twice that number without HAI as controls. Patients will be asked to complete five questionnaires: the first during their stay, and four others during the year following discharge from their recruitment admission (1, 3, 6 and 12 months). Multiple data collection methods will include clinical case note review; patient-reported outcome; linkage to electronic health records and qualitative interviews. Outcomes collected encompass infection types; morbidity and mortality; length of stay; quality of life; healthcare utilisation; repeat admissions and postdischarge prescribing. Ethics and dissemination The study has received a favourable ethical opinion from the Scotland A Research Ethics Committee (reference 16/SS/0199). All publications arising from this study will be published in open-access peer-reviewed journal. Lay-person summaries will be published on the ECONI website.

Yet, not all of them have so far fully engaged in this area. This paper reviews the state of the art on trends in decarbonisation, and outlines the need for decarbonisation efforts at universities. It also reports on a survey aimed at ascertaining the extent to which universities in a sample of 40 countries across the various geographical regions are engaged in carbon reduction efforts, identifying the challenges faced. Results The study has shown that the literature on the topic has been evolving over time and that increasing a given university’s energy supply from renewable energy sources has been the cornerstone of university-based climate action plans. The study also indicates that even though several universities are concerned with their carbon footprint and actively seeking ways to reduce it, there are some institutional obstacles that need to be overcome. Conclusions A first conclusion which can be drawn is that efforts on decarbonisation are becoming more popular, with a special focus being placed on the use of renewable energy. Also, the study has shown that, from the range of efforts being made towards decarbonisation, many universities are setting up a team with carbon management responsibilities, have Carbon Management Policy Statements, and review them. The paper points towards some measures which may be deployed, so as to allow universities to take better advantage of the many opportunities an engagement in decarbonisation initiatives offers to them.info:eu-repo/semantics/publishedVersio

Rapid carbon accumulation at a saltmarsh restored by managed realignment exceeded carbon emitted in direct site construction

Increasing attention is being paid to the carbon sequestration and storage services provided by coastal blue carbon ecosystems such as saltmarshes. Sites restored by managed realignment, where existing sea walls are breached to reinstate tidal inundation to the land behind, have considerable potential to accumulate carbon through deposition of sediment brought in by the tide and burial of vegetation in the site. While this potential has been recognised, it is not yet a common motivating factor for saltmarsh restoration, partly due to uncertainties about the rate of carbon accumulation and how this balances against the greenhouse gases emitted during site construction. We use a combination of field measurements over four years and remote sensing to quantify carbon accumulation at a large managed realignment site, Steart Marshes, UK. Sediment accumulated rapidly at Steart Marshes (mean of 75 mm yr-1) and had a high carbon content (4.4% total carbon, 2.2% total organic carbon), resulting in carbon accumulation of 36.6 t ha-1 yr-1 total carbon (19.4 t ha-1 yr-1 total organic carbon). This rate of carbon accumulation is an order of magnitude higher than reported in many other restored saltmarshes, and is somewhat higher than values previously reported from another hypertidal system (Bay of Fundy, Canada). The estimated carbon emissions associated with the construction of the site were ~2–4% of the observed carbon accumulation during the study period, supporting the view that managed realignment projects in such settings may have significant carbon accumulation benefits. However, uncertainties such as the origin of carbon (allochthonous or autochthonous) and changes in gas fluxes need to be resolved to move towards a full carbon budget for saltmarsh restoration

Participation and retention in a green tourism certification scheme

Tourism certification schemes offer a transitional procedure to a more transparent and sustainable tourism product. Engaging current and previous Green Tourism Business Scheme (GTBS) members in Scotland, this research addresses issues of retention affecting progression of sustainable tourism supply. Quantitative analysis tracking GTBS members over three time points reveals 2% growth but conceals significant flux in membership. Retention was calculated at 66%, where business type analysis discloses distinct issues among accommodation providers with 42% departing the scheme. Decline is greatest among B&B and guesthouses (61%), where poor and falling recruitment coincides with very poor retention (33%). Our analysis demonstrates that slow growth in membership is primarily a result of enterprises choosing to leave the scheme, rather than poor recruitment. Questionnaires from past and present GTBS members (n = 109) confirm the importance of personal proenvironmental philosophies and perceived business benefits in attracting members, yet anticipated benefits do not always materialise. The main reasons for leaving the GTBS relate to membership cost and unrealised benefits. Lack of scheme awareness, management, criteria, bureaucracy and time commitment were further departure factors. The paper offers some suggestions to address issues and enhance retention leading to sustainable growth among tourism certification schemes

Mainstreaming climate change education in UK higher education institutions

Key messages: • Mainstreaming Climate Change Education (CCE) across all learning and operational activities enables Higher Education Institutions (HEIs) to better serve their core purpose of preparing learners for their roles in work and wider society, now and in the future. • Student and employer demand for climate change education is growing, not just in specialist subjects but across all degree pathways. • The attitudes, mindsets, values and behaviours that graduates need to engage with climate change include the ability to deal with complexity, work collaboratively across sectors and disciplines and address challenging ethical questions. • The complexity of the climate crisis means all disciplines have a role to play in delivering education for the net-zero transition. Embedding interdisciplinarity is crucial to ensuring that our response to climate change makes use of all of the expertise HEIs have to offer and promotes knowledge exchange and integration for students and staff. • Student-centered CCE, including peer-to-peer learning, is a powerful tool for facilitating an inclusive and empowering learning experience, and developing graduates as change agents for the climate and ecological crisis. • HEIs should develop learning outcomes for CCE that include understanding the scale, urgency, causes, consequences and solutions of climate change; how social norms and practices are driving the climate crisis; and the ability to identify routes to direct involvement in solutions via every discipline. • Pedagogical approaches to teaching CCE should enable learners to engage with, and respond to, climate change as a “real-world” problem, such as through experiential learning. • Further recommendations for the HEI sector include developing a strategy for aligning CCE teaching provision with governance structures; partnering with industry, government and third sector organisations to enable context-specific CCE; and working with trade unions and accreditation bodies to enable curriculum reform
