At one National Trust historic property, this mechanism has been used to encourage air movement behind books as a possible strategy to reduce the risk of mould growth. It is believed that including ventilation holes as a passive design solution to promote airflow within micro-environments could prevent decay from occurring in the archives of historic buildings. This paper investigates the mechanisms that cause airflow behind bookshelves using field measurements in three National Trust historic libraries. The measurements indicate that small but measurable velocities, up to 4 cm/s, can be passively generated behind bookshelves. Air movement in such confined micro-environments is probably caused by a combination of natural convection, caused by temperature differences between the walls and the interior and the exterior of the bookshelf, and forced convection due to drafts in the surrounding environment. While in some cases one mechanism prevailed, both mechanisms may be present simultaneously in most cases. Further research is needed to clarify how surface temperature drives air motion behind shelves.</p>","PeriodicalId":75271,"journal":{"name":"UCL open environment","volume":"6 ","pages":"e1976"},"PeriodicalIF":0.0,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11440355/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142334030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The moisture buffering quality of lime causes adsorption and desorption of moisture which moderates the indoor relative humidity. Its vapour permeability is also influential in moisture transfer across the building envelope. Lime plaster also has a self-healing quality which prevents the formation of inner cracks. Moreover, its strength increases with time leading to a longer life span. In old structures, an important function is the breathability of ceilings and walls. Hence, it is often used in conservation projects where it improves the appearance and durability of old buildings. Often organic additives employed to impart certain qualities to the lime mortar/plaster led to mould growth. Mould growth degrades indoor air quality, and the occupant health is compromised. To avoid mould-related problems, it is necessary to understand the behaviour of lime plaster with respect to the indoor relative humidity and surface moisture content. This paper focuses on the hygrothermal performance of lime plaster in naturally ventilated residential spaces. Surveys were carried out in 45 traditional buildings in Ahmedabad in India with measurements of ambient variables, such as temperature, relative humidity, wall moisture content, etc. The mould growth patterns of these spaces are related to the measured variables and wall characteristics. Hygrothermal simulations of some spaces were also carried out to observe the moisture buffering of lime plaster. Experimental observations were then compared to simulation results to see if the predictions of the hygrothermal models were realistic.</p>","PeriodicalId":75271,"journal":{"name":"UCL open environment","volume":"6 ","pages":"e1988"},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11443221/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142362560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Education can play a profound role in this transformation as it is fundamental to building a society with knowledge, skills and motivation to tackle climate change so as to regenerate ecological and social systems. This commentary reflects on multiple dimensions of education's role, focusing particularly on schools and the important contribution that all subjects can make towards developing interdisciplinary, complex understandings of the environmental emergency and living more sustainably. Drawing from a recent nationwide survey of teachers in England carried out by the UCL Centre for Climate Change and Sustainability Education, we highlight a troubling lack of engagement in formal professional development related to climate change and sustainability, even amongst a 'climate change engaged' cohort of teachers, and the imperative for comprehensive professional learning for teachers from across all subjects and year levels.</p>","PeriodicalId":75271,"journal":{"name":"UCL open environment","volume":"6 ","pages":"e1987"},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11323742/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141984153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These challenges are complex and require an international and transdisciplinary approach to research, with research skills and expertise from different disciplines, sectors and regions. In addressing this, a key goal of the research project, Blue Communities, was to create and expand mutual interdisciplinary capacity of both United Kingdom and Southeast Asian Partners. An existing questionnaire on research capacity was uniquely adapted to include interdisciplinary and international aspects and distributed for the first time as an online survey to the participants of the Blue Communities project comprising researchers across all career stages. Participants were asked about their perceptions of the research capacity and culture of their organisation, team and self and whether they believed any aspects have changed since their involvement with the project. Greatest improvement was seen at the self-level where results indicated a positive relationship between an individual's current success or skill and their improvement over the course of the research project across 18 out of 22 aspects of research capacity for Southeast Asian, and two for UK respondents. The conflict between achieving research aims, building research capacity and making societal impact was evident.

Effective interventions aimed at cultivating this practice are, however, hampered by the paucity of theory- and evidence-based behavioural research in this context. This study aims to systematically determine a set of behaviour change interventions likely to be effective at promoting planting in front gardens amongst UK householders. The Behaviour Change Wheel framework was applied. Behavioural systems mapping was used to identify community actors relevant to front gardening. Potential behavioural influences on householders' front gardening were identified using the Capability, Opportunity, Motivation, Behaviour model. Using peer-reviewed scientific findings as evidence, behavioural influences were systematically linked to potential intervention strategies, behaviour change techniques and real-world implementation options. Finally, intervention recommendations were refined through expert evaluations and local councillor and public stakeholder feedback, evaluating them against the Acceptability, Practicability, Effectiveness, Affordability, Side effects and Equity criteria in a UK implementation context. This study formulated 12 intervention recommendations, implementable at a community level, to promote front gardening. Stakeholder feedback revealed a preference for educational and supportive (social and practical) strategies (e.g., community gardening workshops, front gardening 'starter kits') over persuasive and motivational approaches (e.g., social marketing, motivational letters from the council to householders). Householders' front gardening behaviour is complex and influenced by the behaviour of many other community actors. It also needs to be understood as a step in a continuum of other behaviours (e.g., clearing land, gardening, waste disposal). This study demonstrates the application of behavioural science to an understudied implementation context, that is, front gardening promotion, drawing on a rigorous development process promoting a transparent approach to intervention design. Stakeholder consultation allowed relevance, feasibility and practical issues to be considered. These improve the likely effectiveness of interventions in practice. The next steps include evaluating the proposed interventions in practice.</p>","PeriodicalId":75271,"journal":{"name":"UCL open environment","volume":"6 ","pages":"e3147"},"PeriodicalIF":0.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11152043/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141263604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Correspondingly, the topic of the so-called <i>environmentally driven migration</i> entered the EU discourse at the dawn of the new millennium. Considering the EU's interest in the human rights and environmental/climate issue areas, I argue it is important to ask what the Union's approach to this matter has been. Thus, this article assesses the European Union discourse related to the topic of environmental migration over the past 20-year period. Through the theoretical lens of the Copenhagen School of Security Studies and the normative power EU conception, this paper critically analyses the EU's securitisation of climate change in relation to persons referred to as environmental migrants. Based on a qualitative discourse analysis, the preliminary results imply that the topic has been receding into the background of the EU agenda. In line, environmental migrants have been pushed aside by a multiplicity of other subjects threatened by climate change, thus receiving lesser attention in the EU climate change and migration management policies. Overall, the findings show a shift from an alarmist discourse to more pragmatism on the EU's behalf and a larger focus on adaptation and resilience in most affected areas. With this in mind, this article questions the normative standard the EU sets for itself when it comes to the case of environmental migrant protection.</p>","PeriodicalId":75271,"journal":{"name":"UCL open environment","volume":"6 ","pages":"e1975"},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10996845/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140853857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
