A hierarchical multilevel approach in assessing factors explaining country-level climate change vulnerability
Assessing vulnerability is key in the planning of climate change adaptation policies and, more importantly, in determining actions increasing resilience across different locations. This study presents the results of a hierarchical linear multilevel modeling approach that utilizes as dependent variable the Notre Dame Global Adaptation Initiative (ND-GAIN) Climate Change Vulnerability Index and explores the relative impact of a number of macro-level characteristics on vulnerability, including GDP, public debt, population, agricultural coverage and sociopolitical and institutional conditions. A 1995–2016 annual time series that yields a panel dataset of 192 countries is employed. Findings suggest that country-level climate change vulnerability is responding (strongly) to the majority of the explanatory variables considered. Findings also confirm that less-developed countries demonstrate increased vulnerability compared to the developed ones and those in transition stages. While these results indeed warrant further attention, they provide a background for a more nuanced understanding of aspects defining country-level patterns of climate vulnerability.</jats:p
A portable air-quality station based on thick film gas sensors for real time detection of traces of atmospheric pollutants
Different functional materials, single or mixed nano-crystalline semiconductor oxides, were synthesized via appropriated wet-chemistry routes. The powders were used to fabricate metal oxide (MOX) thick film gas sensors. Portable monitoring stations based on the aforementioned sensors were prepared, including electronics for acquisition, processing and wireless transmission of the data. Results of long term trials in field, carried out locating few units closely to as many conventional fixed-site monitoring stations, have been reported. The comparison was performed between the temporal evolution of the conductivity changes of the sensors with the pollutants' concentrations, as measured by the analytical instruments
Coping with floods: impacts, preparedness and resilience capacity of Greek micro-, small- and medium-sized enterprises in flood-affected areas
Purpose: This paper aims to investigate aspects of flood experience, attitudes and responses of micro-, small- and medium-sized enterprises (MSMEs) in Greece and to indicate a typology of strategies associated with their relative effort to build flood resilience capacity. Design/methodology/approach: A qualitative study protocol was used, based on pertinent literature that considers how business entities withstand, adapt and/or recover from non-linear climate change impacts, natural hazards and extreme weather. Data was obtained by conducting semi-structured interviews with 82 MSMEs’ owners-managers who had recently experienced flooding. Findings: The study reports limited activities of MSMEs towards flood resilience capacity despite the threat of relevant disasters. Findings suggest that most owners-managers of these enterprises are not adequately preparing their businesses for the impacts of flooding. Research limitations/implications: The findings call for multi-level and dynamic perspectives to be examined in assessing MSME resilience capacity to floods. It is attitudinal, managerial, organisational, behavioural and regulatory (as well as other institutional) factors that merit further investigation. Such an investigation would allow a better understanding as to whether these factors hinder or enable conditions for microeconomic flood preparedness and resilience as well as how they may interact with each other or create feedback loops. Practical implications: The study carries managerial implications and policy recommendations in terms of nurturing opportunities towards awareness-raising campaigns for reducing deficits in managerial knowledge and competencies. It also encapsulates practical implications in terms of emphasising supporting mechanisms from key institutional stakeholders to allow MSMEs scan available options they have in effectively reinforcing the business premises from the forces of rising waters. Originality/value: Most of the related studies have examined flood impacts, responses and/or resilience capacity at the household- or community-level. Empirical work that is conducted to ascertain how MSMEs cope with flooding remains thin on the ground. In response to this, the current study and the typology of MSMEs’ strategic postures that are suggested seek to contribute to this under-researched topic
Sustainability and procurement practices in higher education institutions: Barriers and drivers
© 2019 A review of the literature reveals the scant research on sustainable procurement in the public sector, and in particular higher education institutions (HEIs). In this context, this paper aims to contribute to an emerging stream of research on drivers and challenges which higher education institutions and the extent to which they are endorsing sustainable procurement practices. The study is based on a survey of HEIs around the world, drawn from a network of sustainability practitioners and researchers at these institutions. Design of the survey drew on existing studies of barriers and enablers, the use of vignettes to provoke ideas among the research team, and a pilot study. Crucially, the study seeks to shed light on both drivers and critical barriers affecting the implementation of sustainable procurement at universities. The results and discussion identify previously unidentified barriers and enablers, and further suggest that smaller HEI have some catching up to do. Policy recommendations are presented and approaches on how to overcome barriers to sustainable procurement are set forth. These centre on the proposal that HEIs should consider developing a reflexive strategy to procurement purchasing policy, and to ensure there are suitable means for its implementation

Advancing the sustainable development goals: evidence from leading European banks
The Sustainable Development Goals (SDGs) reflect grand challenges the global community needs to address in order to ensure economic welfare, environmental quality as well as social cohesion and prosperity for future generations. In this respect, the role of the banking sector, among other critical business entities and key stakeholders, is vital. The purpose of our paper is to examine how comprehensively the reported performance of banks aligns with the endorsement of the SDGs. We employ the well-established framework of the Global Reporting Initiative (GRI) performance indicators for a comparative assessment of the nonfinancial performance disclosed in the annual sustainability reports. Focusing on a small sample of leading European banks, we find an overall low contribution to the SDGs. Furthermore, each bank’s contribution remains particularly heterogeneous towards most individual SDG goals. Likewise, bank-specific strategies drive the most extensively addressed SDGs, overlooking any critical importance of certain GRI indicators with multifaceted impact across several SDGs. The study sets forth managerial implications for improving effective reporting of SDG performance. It concludes with emerging opportunities for enhancing disclosure of SDGs contribution and highlights future research perspectives towards industry-wide shared-value appraisal under the scope of these pressing grand challenges
Towards a common future: revising the evolution of university-based sustainability research literature
The field of sustainability has evolved considerably since the report “Our Common Future” was published in 1987. Whereas matters related to sustainable development used to be of marginal interest in the 1980s, it has substantially evolved since, and have become mainstream. As a result, there is a plethora of research on different aspects, whose focus has also been influenced by societal developments. This line of thinking also applies to sustainability research in higher education, a special and central field. Unfortunately, the variety of research on matters of sustainable development in universities makes it difficult to obtain an insight into its current status, and to ascertain how it has evolved since 1987. Based on the perceived need to fill this gap, a study focusing on the evolution of university-based sustainability research literature has been undertaken. The study entailed approximately 1700 papers published between 1987 and 2019, being one of the most comprehensive studies on this field ever undertaken. Apart from performing a bibliometric analysis using science mapping software tools, the research clustered the research into some key areas. The results suggest that, whereas impressive, the evolution of university-based sustainability research has been uneven, and calls for a more balanced emphasis to as to cover some research areas which have so far been neglected. The implications of this work are twofold: it will support the further development of the university-based sustainability research literature, and will help to address some thematic gaps, which are seen today, and to which greater attention is needed
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 students’ 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

Revisiting the dynamics of forest area change: A panel data assessment
This study employs a panel dataset on forest area of 22 countries and for the time period 1995-2016 in order to provide an up-todate assessment on determinants of forest area change. Our set of explanatory variables is drawn from the Environmental Kuznets curve hypothesis and well-established factors affecting forest area change. In this respect, macroeconomic stability, socioeconomic development, institutional efficiency and quality of governance are taken into account to assess the cumulative nature of changes in forest cover. Using static and dynamic specifications our analysis produce different results with an inverted U-shape curve only in the static case and an inverted N-shape relationship in the dynamic specifications. Specifically, using an appropriate fixed effects model validates the EKC hypothesis finding an inverted U-shaped curve with high within-the-sample turning points. The random coefficients method applied does not support the EKC hypothesis in all possible specifications while the orthogonal deviations GMM estimates indicate the presence of an inverted U-shape relationship in all cases with lower cases within-the-sample turning points. A slow adjustment rate is found in all dynamic specifications indicating the need of around four time periods for a country to adjust to the LR equilibrium level of forest recovery. © 2020 Elsevier GmbH.
