Integrative Approaches to Environmental Sustainability at Universities: an overview of challenges and priorities

The principles of sustainable development are becoming extremely relevant for organisations. In the case of universities, these institutions can act as agents in promoting these principles within society. The literature contains a wide range of studies which show how universities may play a critical role in disseminating sustainability principles on the one hand, and their translation into practice, on the other. At present, many Higher Education Institutions are becoming more aware of their impact on the environment, and trying to understand the environmental needs and implications of their operations. Going further, some universities are incorporating sustainability principles into their activities. One of the questions that universities are now facing is how education for sustainable development can be translated into practice so that it can be effective in transforming society. This paper will discuss the need for and the usefulness of integrative approaches to implement sustainable development in higher education. In addition to a theoretical review of the state of the art, the paper will use case studies from the Hamburg University of Applied Sciences (Germany) and Bournemouth University (UK), to illustrate the effectiveness of integration of sustainable development principles in university research and teaching activities, and the many benefits integrative approaches may bring about

Sustainable Development Goals and sustainability teaching at universities: falling behind or getting ahead of the pack?

The fact that the world community is engaged in pursuing the Sustainable Development Goals (SDGs) means that an unrivalled opportunity is provided to universities, both in respect of teaching and in research, on individual SDGs, as well as in pursuing their “third mission” linking up with external stakeholders and society. However, not many universities have realised that and many are falling behind. This paper explores the many advantages of the introduction of the SDGs into teaching and suggests that it can catalyse the engagement of students in Higher Education Institutions (HEI) with the concepts of sustainability. The paper fills in a research gap by surveying the current state of the art regarding the theme, presenting current data outlining the extent to which HEI are using SDGs to support their sustainability work. The reasons why some institutions are currently not engaging is also shown. The paper, which consists of a worldwide survey deployed to collect data on the SDGs and sustainability teaching at universities, concludes by providing some recommendations aimed at encouraging further engagement of HEI in incorporatingSDGs as part of their teaching programs. This research is unique in the sense that it provides for the first time offers an overview of the level of emphasis selected universities currently place on the SDGs. Finally, it provides a contribution to current state of knowledge by outlining some actions universities may take, to move forward with their implementation

Sustainable Development Policies as Indicators and Pre-Conditions for Sustainability Efforts at Universities: fact or fiction?

Purpose - There is a widely held belief that Sustainable Development (SD) policies are essential for universities to successfully engage in matters related to sustainability, and are an indicator of the extent to which they are active in this field. This paper examines the evidence which currently exists to support this assumption. It surveys a sample of universities in Brazil, Germany, Greece, Portugal, South Africa, United Kingdom (UK) and United States of America (USA) to ascertain the extent to which universities that are active in the field of sustainable development have formal policies on sustainable development, and whether such policies are a pre-condition for successful sustainability efforts. Design/methodology/approach –The study involved 35 universities in these seven countries (five universities respectively). A mixed-methods approach has been used, ranging from document analysis, website analysis, questionnaires and interviewing. Findings – Although only 60% of the sampled universities had a policy that specifically addressed SD, this cannot be regarded as an indicator that the remaining 40% are not engaged with substantial actions that address SD. Indeed, all of the universities in the sample, regardless of the existence of a SD formal policy, demonstrated engagement with environmental sustainability policies or procedures in some form or another. This research has been limited by the availability and ability to procure information from the sampled universities. Despite this, it is one of the largest research efforts of this kind ever performed. Originality/value – Our findings provide some valuable insights about the connections between SD policies on the one hand, and the practice of SD in higher education institutions on the other

Drought and the interannual variability of stem growth in an aseasonal, everwet forest

Linking drought to the timing of physiological processes governing tree growth remains one limitation in forecasting climate change effects on tropical trees. Using dendrometers, we measured fine-scale growth for 96 trees of 25 species from 2013 to 2016 in an everwet forest in Puerto Rico. Rainfall over this time span varied, including an unusual, severe El Niño drought in 2015. We assessed how growing season onset, median day, conclusion, and length varied with absolute growth rate and tree size over time. Stem growth was seasonal, beginning in February, peaking in July, and ending in November. Species growth rates varied between 0 and 8 mm/year and correlated weakly with specific leaf area, leaf phosphorus, and leaf nitrogen, and to a lesser degree with wood specific gravity and plant height. Drought and tree growth were decoupled, and drought lengthened and increased variation in growing season length. During the 2015 drought, many trees terminated growth early but did not necessarily grow less. In the year following drought, trees grew more over a shorter growing season, with many smaller trees showing a post-drought increase in growth. We attribute the increased growth of smaller trees to release from light limitation as the canopy thinned because of the drought, and less inferred hydraulic stress than larger trees during drought. Soil type accounted for interannual and interspecific differences, with the finest Zarzal clays reducing tree growth. We conclude that drought affects the phenological timing of tree growth and favors the post-drought growth of smaller, sub-canopy trees in this everwet forest

Fact and fiction in housing research: utilizing the creative imagination

As much of our conceptual framework is informed by the experience of the imagination, there is much to be learnt from a study of various creative forms. Narrative fiction can be one such form, allowing us to gain a useful insight into complex features of social life. The purpose of this article is to investigate the treatment of housing issues in contemporary literature in order to gain insights into attitudes, experiences and interpretations from the perspective of a broad cultural milieu. Discussions of professionalism, housing tenure and homelessness have tended to be conducted within a narrow framework and adopted orthodox modes of evaluation. Consequently, the neglect of housing within a wider cultural context has reinforced the isolation of housing issues. The article argues that although discussions of housing and housing policy have been seriously limited within the contemporary novel, there are a number of key insights that can be gained from a discussion of issues within a fictional setting

Framing the Real: Lefèbvre and NeoRealist Cinematic Space as Practice

In 1945 Roberto Rossellini's Neo-realist Rome, Open City set in motion an approach to cinema and its representation of real life – and by extension real spaces – that was to have international significance in film theory and practice. However, the re-use of the real spaces of the city, and elsewhere, as film sets in Neo-realist film offered (and offers) more than an influential aesthetic and set of cinematic theories. Through Neo-realism, it can be argued that we gain access to a cinematic relational and multidimensional space that is not made from built sets, but by filming the built environment. On the one hand, this space allows us to "notice" the contradictions around us in our cities and, by extension, the societies that have produced those cities, while on the other, allows us to see the spatial practices operative in the production and maintenance of those contradictions. In setting out a template for understanding the spatial practices of Neo-realism through the work of Henri Lefèbvre, this paper opens its films, and those produced today in its wake, to a spatio-political reading of contemporary relevance. We will suggest that the rupturing of divisions between real spaces and the spaces of film locations, as well the blurring of the difference between real life and performed actions for the camera that underlies much of the central importance of Neo-realism, echoes the arguments of Lefèbvre with regard the social production of space. In doing so, we will suggest that film potentially had, and still has, a vital role to play in a critique of contemporary capitalist spatial practices

The indirect response of an aquatic ecosystem to long-term climate-driven terrestrial vegetation in a subalpine temperate lake

Aim: To assess whether climate directly influences aquatic ecosystem dynamics in the temperate landscape of Tasmania or whether the effects of long-term climatic change are mediated through the terrestrial environment (indirect climate influence). Location: Paddy’s Lake is located at 1065 m a.s.l. in temperate north-west Tasmania, a continental island south-east of mainland Australia (41°15–43°250 S; 145°00– 148°150 E). Methods: We developed a new 13,400 year (13.4 kyr) palaeoecological dataset of lake sediment subfossil cladocerans (aquatic grazers), bulk organic sediment carbon (C%) and nitrogen (N%) and d13C and d15N stable isotopes. Comparison of this new data was made with a recently published pollen, geochemistry and charcoal records from Paddy’s Lake. Results: Low cladoceran diversity at Paddy’s Lake is consistent with other temperate Southern Hemisphere lakes. The bulk sediment d15N values demonstrate a significant lagged negative response to pollen accumulation rate (pollen AR). Compositional shifts of dominant cladoceran taxa (Bosmina meridionalis and Alona guttata) occur following changes in both pollen AR and pollen (vegetation) composition throughout the 13.4 kyr record at Paddy’s Lake. The d15N values demonstrate a significant positive lagged relationship to the oligotrophic:eutrophic cladoceran ratio. Main conclusions: Long-term changes in cladoceran composition lag changes in both pollen AR and terrestrial vegetation composition. We interpret pollen AR as reflecting climate-driven changes in terrestrial vegetation productivity and conclude that climate-driven shifts in vegetation are the principal driver of the cladoceran community during the last ca. 13.4 kyr. The significant negative lagged relationship between pollen AR and d15N reflects the primary control of vegetation productivity over within-lake nutrient status. Thus, we conclude that the effects of long-term climate change on aquatic ecosystem dynamics at our site are indirect and mediated by the terrestrial environment. Vegetation productivity controls organic soil development and has a direct influence over lake trophic status via changes in the delivery of terrestrial organic matter into the lake

An Assessment of Attitudes and Perceptions of International University Students on Climate Change

Universities have an unrivaled potential to educate students on climate change issues and to actively engage them in climate affairs, both as citizens and influencers of future professions. Despite this potential and the many advantages of university student engagement in climate change, less emphasis has been given to understanding their attitude and perceptions towards climate change, in a way that may guide changes in the curriculum and teaching practices. Based on the need to address the existing literature gap, this article assesses university studentś attitudes and perceptions toward climate change at the international level. This study comprises a survey of a sample of universities across the world and uses statistical analysis to identify the most important trends across geographical locations of the universities. The study revealed that university students are aware of climate change and associated risks. The university students believe that climate change education is a means to shape their attitude and equip them with relevant skills and knowledge so as to influent others. The awareness of university students is inextricably linked to their field of study and participation in various climate change events. Furthermore, the student’s knowledge of climate change risks varies across gender, age, and academic education. The study provides recommended universities to include climate change issues in their curricular and extracurricular programs so as to prepare future professionals to cope with the far reaching challenges of a climate change

Fifteen species in one: deciphering the Brachionus plicatilis species complex (Rotifera, Monogononta) through DNA taxonomy

Understanding patterns and processes in biological diversity is a critical task given current and rapid environmental change. Such knowledge is even more essential when the taxa under consideration are important ecological and evolutionary models. One of these cases is the monogonont rotifer cryptic species complex Brachionus plicatilis, which is by far the most extensively studied group of rotifers, is widely used in aquaculture, and is known to host a large amount of unresolved diversity. Here we collate a dataset of previously available and newly generated sequences of COI and ITS1 for 1273 isolates of the B. plicatilis complex and apply three approaches in DNA taxonomy (i.e. ABGD, PTP, and GMYC) to identify and provide support for the existence of 15 species within the complex. We used these results to explore phylogenetic signal in morphometric and ecological traits, and to understand correlation among the traits using phylogenetic comparative models. Our results support niche conservatism for some traits (e.g. body length) and phylogenetic plasticity for others (e.g. genome size)
