The purpose of this study was to conceptualise a framework that reflects an intertwined relationship between the green board committee and firm performance. Agency and stakeholder theories hold a basic notion of supporting the relationship between the green board committee and firm performance. The moderating role of intellectual capital (IC) was introduced in the intertwined relationship between green board committees and firm performance based on a resource-based view theory. This study proposes a new measurement index, namely, the “green board committee index”, to measure the green practices of organisations. This index is comprised of four dimensions: strategy and policymaking, monitoring and control, sustainability, and risk management. The current study hypothesised a significant and positive relationship between the green board committee and firm performance. It was believed that the moderation effect of IC strengthens the relationship between the green board committee and firm performance. The data for this study were proposed to be measured through a content analysis of the company’s annual and embedded reports and a Thomson Reuters DataStream terminal. It adds to the body of knowledge by alluding to an integrated notion of green board committees and IC concerning firm performance. The mentioned conceptual framework sends signals to legislators, regulators, policymakers, and practitioners on the critical insights and actions of green board committees in setting strategies and objectives, addressing sustainability issues, forging a relationship with stakeholders, and increasing the firm’s value from the business operations.

Published: October 2021

Facing the big data wave, this study applied artificial intelligence to cite knowledge and find a feasible process to play a crucial role in supplying innovative value in environmental education. Intelligence agents of artificial intelligence and natural language processing (NLP) are two key areas leading the trend in artificial intelligence; this research adopted NLP to analyze the research topics of environmental education research journals in the Web of Science (WoS) database during 2011–2020 and interpret the categories and characteristics of abstracts for environmental education papers. The corpus data were selected from abstracts and keywords of research journal papers, which were analyzed with text mining, cluster analysis, latent Dirichlet allocation (LDA), and co-word analysis methods. The decisions regarding the classification of feature words were determined and reviewed by domain experts, and the associated TF-IDF weights were calculated for the following cluster analysis, which involved a combination of hierarchical clustering and K-means analysis. The hierarchical clustering and LDA decided the number of required categories as seven, and the K-means cluster analysis classified the overall documents into seven categories. This study utilized co-word analysis to check the suitability of the K-means classification, analyzed the terms with high TF-IDF wights for distinct K-means groups, and examined the terms for different topics with the LDA technique. A comparison of the results demonstrated that most categories that were recognized with K-means and LDA methods were the same and shared similar words; however, two categories had slight differences. The involvement of field experts assisted with the consistency and correctness of the classified topics and documents.

Published: October 2021

In this study, performance assessment of the variable speed compressor-based air source heat pump (ASHP) system as a domestic retrofit technology instead of fossil fuel-based heating technologies for the 1900s Mid terraced house is investigated. The assessment was conducted considering operating mode of control and heat supply temperature impact of the system. In the literature, ASHP system experimental development with variable speed mode (VSM) of control in comparison to fixed speed mode (FSM) of control at low to medium and high heat supply temperature in the context of UK was found with very limited number of studies, but without considering retrofit application. The focus of the earlier studies was on the individual components and performance improvement. The designed heat pump (HP), developed, and tested at constant heat load, simulating the real domestic heat demand under the controlled laboratory conditions and numerical modeling is utilized for the analysis purposes. The HP performance, energy demand, carbon emissions, and cost varies significantly due to changing heat supply temperature (35 °C, 45 °C, and 55 °C), control mode and accordingly the carbon emission and cost savings are achieved. The oil and gas boilers ranges from conventional to highly efficient type and evaluated in terms of annual running cost, energy consumptions, and carbon emissions in comparison with the HP system. Additionally, a comparative study with the existing retrofitted very high temperature ASHP inside the house is conducted. The developed HP at 55 °C could not defeat the very high heat supply temperature HP system (75 °C supply temperature) in performance and cost savings but become attractive at low supply temperature (35 °C). The HP system in VSM at low heat supply temperature instead of gas boiler (90% efficiency) could cut the annual carbon emissions by 59% but with additional 6% running cost for the Mid terraced test house in Belfast climatic conditions.

Published: October 2021

A sustainable circular economy involves designing and promoting products with the least environmental impact. This research presents an experimental performance investigation of direct contact membrane distillation with feed approaching supersaturation salinity, which can be useful for the sustainable management of reverse osmosis reject water. Traditionally, reject water from the reverse osmosis systems is discharged in the sea or in the source water body. The reinjection of high salinity reject water into the sea has the potential to put the local sea environment at risk. This paper presents a design of a solar membrane distillation system that can achieve close to zero liquid discharge. The theoretical and experimental analysis on the performance of the lab scale close to zero liquid discharge system that produces supersaturated brine is studied. The lab-based experiments were conducted at boundary conditions, which were close to the real-world conditions where feed water temperatures ranged between 40 °C and 85 °C and the permeate water temperatures ranged between 5 °C and 20 °C. The feed water was supplied at salinity between 70,000 ppm to 110,000 ppm, similar to reject from reverse osmosis. The experimental results show that the maximum flux of 17.03 kg/m2·h was achieved at a feed temperature of 80 °C, a feed salinity of 10,000 ppm, a permeate temperature of 5 °C and at constant feed and a permeate flow rate of 4 L/min. Whereas for the same conditions, the theoretical mass flux was 18.23 kg/m2·h. Crystal formation was observed in the feed tank as the feed water volume reduced and the salinity increased, reaching close to 308,000 ppm TDS. At this condition, the mass flux approached close to zero due to crystallisation on the membrane surface. This study provides advice on the practical limitations for the use of membrane distillation to achieve close to zero liquid discharge.

Authors: Yetter Eric , Chhin Sophan , Brown John P.
Published: October 2021

Red spruce (Picea rubens) was historically an important and dominant timber species in the central Appalachian mountain range. The tree species is now found in a small fraction of its original home range. Threatened and endangered organisms such as the Cheat Mountain Salamander (Plethodon nettingi) rely on red spruce associated forests for survival. This review provides a background on the history of forest management of red spruce in the central Appalachian region. A meta-analysis was conducted on recent literature (published 2000 or later) of red spruce in the central Appalachian region to highlight key management and conservation concerns. In particular, forest health concerns related to air pollution and climatic stress also are addressed. Approaches to examine the impact of environmental factors on red spruce site productivity are covered. This review also provides sustainable management options for restoration of red spruce in the central Appalachian mountain range.
Strategic Actions for a Sustainable Internationalization of Agri-Food Supply Chains: The Case of the Dairy Industries from Brazil and Germany
Authors: Beber Caetano Luiz , Langer Greta , Meyer Johannes
Published: October 2021

While facing a growing domestic demand of milk and milk products, the Brazilian dairy industry is far behind in terms of competitiveness and sustainability when compared to other national agricultural sectors. Nonetheless, in Germany the leading dairy companies mainly pushed by a saturated domestic market, EU agriculture policy oriented to liberalization of markets, and increasing political and social demands are looking at markets beyond EU. In the context of the increasing globalization of agricultural supply chains, the issue of sustainability gains particular importance in companies’ internationalization strategies. By using expert interviews, this paper investigates strategies for integrating Brazilian and German dairy supply chains and how both sides can benefit from this situation also in terms of sustainability. The analyses show that problems of the industries in both countries basically complement each other at different levels and positive synergies for both sides exist when it comes to sustainable issues, positioning themselves competitively for the future and creating a good position for conquering market shares in a globally growing milk market. This paper proposes an approach for the challenges of such integration, as well as viable solutions to sustainability issues.
Sustainable University: From the Worldwide Conception to the Brazilian Amazonia
Authors: Lopes Jacqueline Bailão da Silva , Vieira Thiago Almeida
Published: October 2021

Higher Education as a transforming instrument in societies raises the need for universities and Higher Education Institutions (HEIs) as a whole to be leaders in the current paradigm of the time. The objectives of this study are to verify and analyze the movement and actions around the world that drove and started the conceptual model of Sustainable University (SU), as well as these ideas that started in Brazil and their implications for the reality of the Brazilian Amazon Region. A timeline has been sketched and provides additional theoretical insights into universities’ involvement in events before and after the sustainable development process. The methodological procedures were based on a wide literature review in scientific databases that gather journals with satisfactory impact factors; with the refinement of the searches, 87 scientific articles supported the analysis of this study. The results show that universities have played a prominent role on the world stage since 1950, in the post-war period. In the 1970s, HEIs sought to engage in the design of the new paradigm, and in the 1980s it is enunciated as Sustainable Development and conceptualized by the Sustainability approach. Universities, which had been active in discussions and events related to sustainability from the late 1980s onwards, began to organize themselves more effectively and promote sustainable initiatives to become examples of sustainability. Currently, many HEIs from countries in Europe and North America stand out in the initiatives. In Brazil, according to a global classifier, some HEIs seek to align themselves towards the SU model. Until 2019, no university in the Brazilian Amazon region had integrated the ranking, but in 2020, two appear in the list. It appears that information on the sustainability of universities inserted in the context of the Brazilian Amazon is still incipient.
Analyzing the Barriers to Reverse Logistics (RL) Implementation: A Hybrid Model Based on IF-DEMATEL-EDAS
Authors: U-Dominic Chukwuebuka M. , Orji Ifeyinwa Juliet , Okwu Modestus
Published: October 2021

Recently, manufacturing companies aspire to implement reverse logistics in response to stakeholders’ requirements to reduce negative environmental consequences, improve organizational sustainable performance and ultimately increase competitive advantage. However, implementing reverse logistics can be impeded by a criteria framework, and necessitates the careful analysis of how such criteria interact with each other in the presence of uncertainty. Thus, in this study, we propose an integrated multi- criteria decision-making (MCDM) methodology that leverages the Decision Making Trial and Evaluation Laboratory (DEMATEL) under Intuitionistic Fuzzy (IF) environment and Evaluation Based on Distance to Average Solution (EDAS). Within the proposed methodology, firstly, the IF-DEMATEL is applied to obtain the interrelationships between the criteria/barriers and then, the EDAS method is applied to prioritize the criteria based on the appraisal scores evaluation. An application case within the Nigerian manufacturing sector was utilized to illustrate the viability of the proposed methodology. The study results indicate that the highly prioritized barriers to implementing reverse logistics within the Nigerian manufacturing sector include low product quality, risk of storing hazardous materials and low technical expertise. Consequently, this study makes a profound contribution to the theory and practice of reverse logistics by presenting an integrated MCDM methodology that can effectively address the criticality of barriers in the way of reverse logistics progression in a complex and uncertain scenario.
Implications of Microbial Community to the Overall Performance of Tree-Box Filter Treating Parking Lot Runoff

Published: October 2021

Most of the studies about stormwater low-impact development technologies (LID) used generalized observations without fully understanding the mechanisms affecting the whole performance of the systems from the catchment to the facility itself. At present, these LID technologies have been treated as black box due to fluctuating flow and environmental conditions affecting its operation and treatment performance. As such, the implications of microbial community to the overall performance of the tree-box filter (TBF) were investigated in this study. Based on the results, summer season was found to be the most suitable season for microorganism growth as greater microorganism count was found in TBF during this season compared to other seasons. Least microorganism count was found in spring which might have been affected by the plant growth during this season since plant penology influences the seasonal dynamics of soil microorganisms. Litterfall during fall season might have affected the microorganism count during winter as, during this season, the compositional variety of soil organic matter changes affecting growth of soil microbial communities. Microbial analyses of soil samples collected in TBF revealed that the most dominant microorganism phylum is Proteobacteria in all the seasons in both inlet and outlet comprising 37% to 47% of the total microorganism count. Proteobacteria is of great importance to carbon, sulfur, and nitrogen cycling in soil. Proteobacteria was followed by Acidobacteria, Actinobacteria, and Chloroflexi which comprises 6% to 20%, 9% to 20%, and 2% to 27%, respectively, of the total microorganism count for each season. Each microorganism phylum was found to have varying correlation to different soil chemical parameters implying the effects of these parameters to microorganism survival in LID technologies. Depending on the target biogeochemical cycle, maintaining a good environment for a specific microbial phylum may be decided. These findings were useful in optimizing the design and performance of tree box filters considering physical, chemical, and biological pollutant removal mechanisms.

The Effects of Technology Innovation Activity on CSR: Emphasizing the Nonlinear and Heterogenous Effects
Authors: Lee Hyunchul , Lee Kyungtag
Published: October 2021

In this study, we systematically investigate several effects of technology innovation activity (TIA)—proxied by Korean listed corporations’ research and development investment—on the performance of corporate social responsibility (CSR) for sustainable corporate growth and value. We find that corporate TIA positively contributes to an increase in CSR performance. Furthermore, our quantile regression estimations point to a heterogeneous effect of TIA, with a significant positive impact on CSR performance at the middle and higher quantiles of the distribution of the dependent variable of CSR performance. Interestingly, we capture a U-shaped nonlinear effect of TIA on the CSR performance of Korean listed corporations. Our findings alert researchers and managers to the importance of a better understanding of the relationship between CSR and TIA for sustainable corporate growth and value.

The populations of the Arctic Ocean coast in Eastern Siberia (Russia) are represented by a multicultural conglomerate of peoples of different origins: Paleo-Asiatic (Chukchi), Uralic (Yukaghirs), Tungusic (Evenks, Evens), Turkic (Yakuts, Dolgans), and Slavic (Russian explorers), who inhabited this territory during various historical periods. However, among the modern Arctic populations there are still “white spots”, such as people of the small village of “Russkoe Ust’ye”, who still have not been thoroughly studied. The main population consists of so called Russian old-settlers—the Russkoustinians. They traditionally distinguish their lineages into three groups identified by their time of settlement. First are the “Pomors”—who according to their legends are considered as the descendants of the first European colonists of the Age of Discovery, who settled the eastern shores of the Arctic Ocean in the 16th century before the inclusion of this territory in the Russian Empire in the early 17th century. Second are the “Cossacks”—who reached the Arctic during explorations of Siberia. The last are the “Zashiversk”—who arrived after the abolition of their hometown. In order to test these hypotheses, we analyzed modern family name diversity based on information on 62 individuals from 36 questionnaires. The analysis revealed that the “Pomors” lineages were presented in five families (43.5%), the “Cossacks” in one family (6.5%), and the “Zashiversk” in 37.1% of families. This fact indicates a probability that this village was founded by Russian Pomors who arrived there by the Northern Sea Routes before the official East Siberian colonization period.
Integrated Water-Power System Resilience Analysis in a Southeastern Idaho Irrigation District: Minidoka Case Study
Authors: Toba Ange-Lionel , Boire Liam , McJunkin Timothy
Published: October 2021

This study investigates the joint water–power system resilience of an irrigation district in southeastern Idaho. Irrigation districts face difficulties in the delivery of water to farmers under drought conditions, during equipment failures, or unplanned infrastructure disruptions. The resilience of interconnected water and power systems can be better analyzed and understood through an integrated approach, using a model that connects the dependencies between the two halves of the system. Using a multi-agent system model capturing both water and power system components, as well as their linkages, we capture the interdependencies of these systems and highlight opportunities for improvement when faced with disruptions. Through simulation scenarios, we examine the system resilience using system performance, quantified as the percentage of met demand of the power and water system, when subjected to drought water year, an unforeseen water demand increase, power outage and dam failure. Scenario results indicate that the effects of low flow years are mostly felt in the power system; unexpected increases in water demand marginally impact irrigation system performance; dams and pumps present vulnerabilities of the system, causing substantial unmet demand during disruptions. Noting the interdependencies between the water–power system halves while leveraging an integrated simulation allows for an insightful analysis of the system impacts during disruptions.
Applying Lean Healthcare to Improve the Discharge Process in a Mexican Academic Medical Center
Authors: Peimbert-García Rodrigo E. , Gutiérrez-Mendoza Luis Meave , García-Reyes Heriberto
Published: October 2021

Lean Thinking has been one of the preferred approaches to improve healthcare processes in developed countries; however, it has been barely used in Latin America. This study presents a Lean implementation in a Mexican public academic medical center. The goal was to reduce the time required to discharge patients from the Internal Medicine Department. This non-experimental intervention study measured, analyzed, and improved the process flow through a time study, value-added/non-value-added analysis, and the four-step quick changeover approach. Once changes were implemented, inferential statistics were used to compare results. Lean implementation allowed reducing the time to discharge patients from 6 to 3 h by eliminating 57% of non-value-added activities and 70% of errors found in discharge orders. This represents a 2% annual capacity increase and a 6.423 h bed made available without investment. Other findings include barriers regarding untrained staff about process improvement and departmental barriers and a successful quick changeover implementation. This is one of the handful of implementations of Lean Healthcare in Latin America. Furthermore, this is one of the very first studies that showcase the implementation of the quick changeover approach in healthcare. Further research should focus on the long-term impact and how the specific environment encourages/discourages future implementations.
“Worse Than What I Read?” The External Effect of Review Ratings on the Online Review Generation Process: An Empirical Analysis of Multiple Product Categories Using Amazon.com Review Data
Authors: Park Young Joon , Joo Jaewoo , Polpanumas Charin , Yoon Yeujun
Published: October 2021

In this paper, we study the online consumer review generation process by analyzing 37.12 million online reviews across nineteen product categories obtained from Amazon.com. This study revealed that the discrepancy between ratings by others and consumers’ post-purchasing evaluations significantly influenced both the valence and quantity of the reviews that consumers generated. Specifically, a negative discrepancy (‘worse than what I read’) significantly accelerates consumers to write negative reviews (19/19 categories supported), while a positive discrepancy (‘better than what I read’) accelerates consumers to write positive reviews (16/19 categories supported). This implies that others’ ratings play an important role in influencing the review generation process by consumers. More interestingly, we found that this discrepancy significantly influences consumers’ neutral review generation, which is known to amplify the effect of positive or negative reviews by affecting consumers’ search behavior or the credibility of the information. However, this effect is asymmetric. While negative discrepancies lead consumers to write more neutral reviews, positive discrepancies help reduce neutral review generation. Furthermore, our findings provide important implications for marketers who tend to generate fake reviews or selectively generate reviews favorable to their products to increase sales. Doing so may backfire on firms because negative discrepancies can accelerate the generation of objective or negative reviews.
Application of Multi-Criteria Decision Approach in the Assessment of Medical Waste Management Systems in Nigeria
Authors: Etim Mmemek-Abasi , Academe Sunday , Emenike PraiseGod , Omole David
Published: October 2021

Globally, the pandemic of COVID-19 has penetrated all spheres of human endeavors, and noteworthy is the tremendous increase in the volume of healthcare wastes generated in Nigeria. There has been an increase in medical waste materials produced as a result of the extensive use of both disposable personal protective equipment (PPE), such as face shields and nose and face masks, and highly infectious waste materials, such as contaminated syringes, needles, and soiled bandages from diagnosed positive cases. Despite the huge volume in waste generation, a standardized evaluation framework is currently lacking in the management of medical wastes in Nigeria. This study has developed a novel assessment framework for managing medical wastes, which is curated from the technical guidelines of the World Health Organization (WHO). The applicability of the framework was examined on seven designated public and private-owned hospitals in Ota. The fuzzy analytical hierarchy process (FAHP) and analytical hierarchy process (AHP) approaches of multi-criteria decision analysis were utilized in modelling an evaluation framework for the objective of medical waste management. Carefully designed interview questionnaires, observations, and site visits were carried out to obtain data from healthcare professionals in Ota. Results show that waste segregation was practiced more decisively in private hospitals than public hospitals. Waste segregation is established as a key determinant in implementing an effective waste management system in any healthcare facility. The success of waste segregation in healthcare institutions is highly dependent on good hospital management, organizational policies, efficient budget planning for waste management, and the operational running cost. Disposal methods investigated were mostly open burning and incessant dumping for most public health care centers. Deficient waste management practices were observed in waste disposal, waste transportation, storage, and organizational policies. While the awareness and capacity building on occupational safety practices and environmental public health is widely known by health workers and waste handlers, compliance and enforcement are critical challenges. The validation of results using fuzzy TOPSIS and a sensitivity analysis shows a high degree of the consistency, stability, and robustness of the model. Findings from the present study can aid decision making, as this will benefit policy makers and key stakeholders in developing more comprehensive and effective medical waste management guidelines in Nigeria. In addition, future decision-making studies could augment the results from the current research by assessing the impact of the pandemic preparedness and response on medical waste management.
Integrating Resilience and Sustainability Criteria in the Supply Chain Network Design. A Systematic Literature Review
Authors: López-Castro Luis Francisco , Solano-Charris Elyn L.
Published: October 2021

Nowadays, Supply Chain Networks (SCNs) must respond to economic, environmental, social, and uncertain considerations. Thus, sustainable and resilience criteria need to be incorporated as key criteria into the Supply Chain Network Design (SCND). This paper, as part of an emerging subject, reviews the literature between 2010 and 2021 that integrates sustainability and resilience on the SCND. The article classifies the literature according to the levels of the SCND, levels of the decision-making (i.e., strategic, tactical, and operational), resilience and sustainability criteria, solving approach, objective criteria, contributions to the Sustainable Development Goals (SDGs), and real-world applications. The main findings allow us to conclude that the decisions regarding the supply chain network design with sustainability and resilience criteria are mainly strategic, focusing on the forward flow. Most works address resilience through the evaluation of scenarios (risk assessment perspective), and in terms of the sustainability perspective, authors mainly focus on the economic dimension through the evaluation of income and costs along the chain. Based on the review and the proposed taxonomy, the paper proposes ideas for future research.
Technology or Institutions: Which Is the Source of Green Economic Growth in Chinese Cities?
Authors: Han Jing , Chen Xi , Sun Yawen
Published: October 2021

To relax the increasingly tight resource and environmental constraints on development, China needs to follow a pattern of growth that comprehensively encompasses economic growth, environmental protection, and resource conservation, namely, green economic growth. The key to achieving green economic growth is to improve green total factor productivity, of which technological innovation and institutional innovation are the primary driving forces. Based on the panel data of 266 cities in China from 2004 to 2018, this paper first uses the Directional Distance Function and Global Malmquist–Luenberger productivity index to measure the urban green total factor productivity to represent urban green economic growth; then, the impact of technological innovation and institutional innovation on urban green economic growth is studied by using the panel Granger causality test and SYS-GMM dynamic panel model. The results are described as follows: China’s urban green total factor productivity shows an increasing trend from 2004 to 2018, and the average growth rate of green total factor productivity is 3.27%, which is far lower than the average GDP growth rate of 9.14%; both technological innovation and institutional innovation can significantly promote the growth of the urban green economy, but institutional innovation has a greater role in promoting the growth of the urban green economy than technological innovation. In addition, the relationship between institutional innovation and urban green economic growth is more stable.

Published: October 2021

The application of asphalt hot mix recycling is one challenge in sustainable road pavement research. In addition to the vast amount of research on the performance of recycled asphalt–concrete, the research on the frictional resistance of recycled hot mix asphalt is still limited. The effects of aged asphalt and aged aggregates on the skid resistance of recycled hot mix asphalt were investigated in this research. The aged asphalt and aged aggregates were carefully extracted from the field-reclaimed asphalt pavement, and the engineering and mechanical properties of aged and virgin aggregates were measured. The degradation of recycled hot mix asphalt was simulated using an accelerated polishing machine to mimic road surface abrasion. Accordingly, the initial and final skid resistances of the recycled hot mix asphalt were determined and correlated with the properties of the aged asphalt and aggregates. The initial skid resistance of recycled hot mix asphalt decreased with reductions in penetration and ductility of the blended asphalt. However, the changes in the blended asphalt properties contributed only small variations to the final skid resistances of the recycled hot mix asphalt. The gradations of recycled hot mix asphalt correlated only with the final skid resistances. The aggregate gradations controlled the characteristics of the final skid resistance since the covered binder was partially polished off from the road surface at this stage.
Coalitions for Landscape Resilience: Institutional Dynamics behind Community-Based Rangeland Management System in North-Western Tanzania

Published: October 2021

The past few decades have seen a continuing shift of natural resource management paradigm towards multifunctional and multi-actor adaptive management in hope of achieving more resilient landscapes. Recognizing the multitude of institutional actors and their roles as well as dynamics helps to understand communal behaviour, its manifestations in the landscape and resilience under changing socioecological circumstances. We examined institutional actors and their functions and relationships in a long-standing community-based natural resource management system, the ngitili, in north-western part of Tanzania. The aim of the research was to deepen understanding on the role of institutional arrangements and their limitations in supporting resilience of community-based management system. Data was collected through group discussions and interviews in three case study villages and district level, and institutional arrangements were analysed using 4Rs framework and social network analysis. The study shows that the management arrangements have evolved with time and are based on locally negotiated roles and collaboration among bureaucratic and socially embedded village level actors. These local level actors are resource poor, which hinders collaboration and implementation of ngitili management functions. External interventions have temporarily increased management efficiency in the villages but they did not create sustained multi-scale collaboration networks to address external threats to the ngitili resources. The results show that diversified funding sources, technical support and benefit sharing mechanisms are required to incentivize sustainable resource management. For the management system to be more resilient, the existing institutional actors and their ability to adapt should be nurtured by awareness raising, wider stakeholder participation and bridging organizations.

Published: October 2021

Land use land cover (LULC) change is one of the main drivers contributing to global climate change. It alters surface hydrology and energy balance between the land surface and atmosphere. However, its impacts on surface air temperature have not been well understood in a dynamic region of LULC changes like Southeast Asia (SEA). This study quantitatively examined the contribution of LULC changes to temperature trends in Myanmar and Thailand as the typical parts of SEA during 1990–2019 using the “observation minus reanalysis” (OMR) method. Overall, the average maximum, mean, and minimum temperatures obtained from OMR trends indicate significant warming trends of 0.17 °C/10a, 0.20 °C/10a, and 0.42 °C/10a, respectively. The rates of minimum temperature increase were larger than maximum and mean temperatures. The decreases of forest land and cropland, and the expansions of settlements land fractions were strongly correlated with the observed warming trends. It was found that the effects of forest land converted to settlement land on warming were higher than forest conversion to cropland. A comprehensive discussion on this study could provide scientific information for the future development of more sustainable land use planning to mitigate and adapt to climate change at the local and national levels.

Published: October 2021

Economic sustainability is closely linked to firm growth and employment stability, making them of great interest to policymakers and business leaders. Insights into the factors that impact employment growth and employment stability aid decision makers to develop policies that encourage economic growth and economic sustainability. This study used World Bank Enterprise Survey data to examine the effect of the business obstacles of financing, labour regulation, and under-skilled workforce on firm growth and on employment stability, estimated by the proportion of permanent to non-permanent workforce in East Asia and Pacific nations. The instrumental variables (IV) method was used with two-stage least squares (2SLS) to account for potential endogeneity between the business obstacles and employment growth and the proportion of permanent to non-permanent workers employed by firms. In addition, the quantile method was applied to capture the partial effect of the reported obstacles across different segments of firm growth. Findings included a significant negative effect of the financing obstacle on employment growth and therefore firm growth, particularly at the lowest levels thereof. In addition, financing and labour regulations obstacles have a significant, negative effect on the proportion of permanent employees in a firm’s workforce.
The Role of Nature-Based Solutions for Improving Environmental Quality, Health and Well-Being
Authors: Liu Hai-Ying , Jay Marion , Chen Xianwen
Published: October 2021

Nature-based solutions (NbS) have been positioned and implemented in urban areas as solutions for enhancing urban resilience in the face of a wide range of urban challenges. However, there is a lack of recommendations of optimal NbS and appropriate typologies fitting to different contexts and urban design. The analytical frameworks for NbS implementation and impact evaluation, that integrate NbS into local policy frameworks, socio-economic transition pathways, and spatial planning, remain fragmented. In this article, the NbS concept and its related terminologies are first discussed. Second, the types of NbS implemented in Europe are reviewed and their benefits over time are explored, prior to categorizing them and highlighting the key methods, criteria, and indicators to identify and assess the NbS’s impacts, co-benefits, and trade-offs. The latter involved a review of the websites of 52 projects and some relevant publications funded by EU Research and Innovation programs and other relevant publications. The results show that there is a shared understanding that the NbS concept encompasses benefits of restoration and rehabilitation of ecosystems, carbon neutrality, improved environmental quality, health and well-being, and evidence for such benefits. This study also shows that most NbS-related projects and activities in Europe use hybrid approaches, with NbS typically developed, tested, or implemented to target specific types of environmental–social–economic challenges. The results of this study indicate that NbS as a holistic concept would be beneficial in the context of climate action and sustainable solutions to enhance ecosystem resilience and adaptive capacity within cities. As such, this article provides a snapshot of the role of NbS in urban sustainability development, a guide to the state-of-the-art, and key messages and recommendations of this rapidly emerging and evolving field.

Much of the literature examining the role of gender in processes of climate change adaptation in the agricultural sector has focused primarily on differences between male and female farmers, implicitly treating men and women as homogenous groups. Where heterogeneity exists within these groups which impacts climate change adaptation efforts and outcomes, an understanding of such intersectionalities is vital to the design of effective and equitable policy. The objective of this study is to investigate whether interaction effects among socio-economic factors are meaningful drivers of observed differences among female farmers in their adoption of climate-smart agricultural (CSA) practices, as well as their use of climate information and financial services. This study employs data from farmer surveys in three Climate-Smart Villages in Latin America, analyzed using ordinal logistic regression and canonical correspondence analysis. The results indicate that important interaction effects are present: the relationship between higher educational attainment and increased adoption of CSA practices, for example, is conditional on the degree of livelihood diversification. The relationship between greater educational attainment and increased use of climate forecasts is likewise conditional on age. These results suggest the need for researchers and policymakers to anticipate potential intersectionalities when designing research efforts and development interventions.

The sharing economy enables the sustainable development of tourism and at the same time contributes to social well-being and economic growth. It also helps to reduce negative impact on the environment and society, and at the same time reduces costs. The purpose of this study is to find out how the sharing economy can contribute to the development of sustainable tourism. This article is intended to identify the opportunities and benefits of the sharing economy in the tourism sector and to describe the impact of the sharing economy on the travel and tourism sector. To achieve this goal, a systematic scientific analysis of literature and quantitative research methods was applied. Seeking development of sustainable tourism, the authors present a theoretical conceptual model that illustrates the contribution of the sharing economy through benefits and factors influencing sharing economy perspectives in tourism. Empirical research was conducted based on factors influencing sharing economy perspectives in tourism transportation services as one of the sharing economy areas. Analysis of the empirical research results showed that the most important factors influencing the respondents’ choices of the ORSC transport sharing platform were price, general approach and comfort.
Czech Preschool Children’s Conceptions about Nature

Published: October 2021

This study focused on young children’s understanding of nature, an issue observed to be a research gap in the scientific community. The question “What nature?” is central to this research. Answers to this question were obtained from 342 children from 21 Czech kindergartens, and results showed 302 preschool and children (aged from 3 to 6.5 years) from the sample displayed a conceptual understanding of nature and expressed their ideas verbally. Qualitative content analysis and comparative analysis (nouns and verbs separately) were performed on the results. Most children interpreted nature through lists of objects or as a space or a concrete place, and most of the objects mentioned related to living nature. Children used verbs describing natural events more often than verbs describing their own or human activities in nature. The comparison between children’s, adults’, and pupils’ concepts of nature shows that children expressed their concepts in a similar, albeit not identical, manner to adults. They expressed the utilitarian and aesthetic value of nature, showed a scientific interest and an emotional connection to nature, and showed their joy in interacting with nature. Although certain similarities in children’s answers were noted, each child understands nature individually. Teachers should respect this fact and consider this in environmental and global education.

Twenty percent of the world’s energy is consumed by the construction sector, including commercial and residential buildings, where 13% is consumed by the residential sector only. Half of the total energy consumed by buildings in Saudi Arabia is specifically attributed to the hot summer season, which, unlike in many other countries in the Middle East, continues for more than 5 months annually. The use of a phase change material (PCM), as an insulator in building materials, can be a solution to provide a comfortable indoor temperature and reduce energy consumption. This study examined two different melting ranges for PCMs RT35 and RT35HC inserted into hollow clay bricks to investigate their thermal behavior and heat storage capacity and compare them with polystyrene foam. To perform this experiment, four chambers were constructed using cement plastering. The data were collected at Jeddah, Saudi Arabia, from mid-November 2020 to the end of February 2021. When the highest temperature was reached during the experiment, PCM RT35 provided a better cooling effect by 13% compared to 24% and 28.56% for PCM RT35HC and foam, respectively, compared to hollow bricks alone. However, when the lowest temperature was reached during the experiment, PCM RT35HC performed better than the other chambers in saving energy and keeping the chamber warm, which was 9.5% for the reference chamber, 7.0% for the foam chamber, and 2.8% for PCM RT35. The maximum energy saving of PCM RT35 was around 1920 kJ, which is around 0.533 kWh, for one wall only, and for PCM RT35HC, it was 2880 kJ, or 0.8 kWh, which can reduce energy consumption of the HVAC system by 97 kWh/m2 and 146 kWh/m2 per year, respectively.
