Objective Sustainability Assessment in the Digital Economy: An Information Entropy Measure of Transparency in Corporate Sustainability Reporting
Authors: Zakaria Mohammed , Aoun Chadi , Liginlal Divakaran
Published: January 2021

The Internet is now a central enabler for sharing sustainability information. Yet, such enablement is complicated through an exponentially increasing array of information. What is lacking in the digital economy are objective and transparent mechanisms to provide reliable assessments of the published sustainability information in a timely and efficient manner. In addressing such limitation, this research proposes an objective automated mechanism for measuring transparency in sustainability reporting using an information entropy-based approach. Through text-mining methods and expert validation, the study built a sustainability dictionary corpus and then applied the corpus for objectively assessing the relative entropy between the probability distributions of words in the sustainability dictionary and those in corporate reports. To demonstrate its effectiveness, the mechanism was empirically applied to compare sustainability reporting of organizations in the energy sector. Here, the research effectively compared cartels with non-cartels by assessing the sustainability reports of major OPEC (Organization of the Petroleum Exporting Countries) and non-OPEC producers spanning a three-year period and found consistent differences in transparency between the two groups. The findings demonstrate likely normative transparency pressures on disaffiliated producers for which cartels may be immune. The automated mechanism holds important theoretical and practical contributions to the field of sustainability as it provides a rapid and objective means for textual analysis of sustainability information, thus promoting transparency in sustainability reporting in the rapidly evolving digital economy.

Authors: Liang Xiaoxu , Lu Yanjun , Martin John
Published: January 2021

During the last 20 years, with the development of Information and Communication Technologies (ICTs), an emerging interest has appeared in Digital Community Engagement (DCE) in the process of cultural heritage management. Due to a growing need to involve a broader community in the Historic Urban Landscape approach, social media are considered one of the most important platforms to promote the public participation process of urban heritage conservation in the context of rapid urbanization. Despite the growing literature on DCE, which has delivered a general overview of different digital technologies and platforms to enhance heritage conservation, little research has been done on taking stock of the utilization of social media in this process. This study aims to fill the research gap by providing a more comprehensive picture of the functionalities of social media platforms and their impacts on sustainable urban development through a systematic literature review. As a result, 19 out of 248 DCE relevant articles are selected as objects to illustrate the contribution of social media. The study identified the characteristics of these applied social media tools, explores their roles and influences in cases. The article concludes that social media offers a platform for a wider range of stakeholders to have a voice in the decision process of cultural heritage management, and it should be widely applied to encourage citizens from all over the world.

Authors: Abu-Hashim Mohamed , Sayed Ahmed , Zelenakova Martina , Vranayová Zuzana , Khalil Mohamed
Published: January 2021

Preserving the sustainable agriculture concept requires identifying the plant response to the water regime and rationing the water for irrigation. This research compares different irrigation designs coupled with a parametric evaluation system on soil water erosion and soil suitability to assess the sites vulnerable to soil erosion based on a soil water erosion model (ImpelERO) in an area of 150.0 hectares, Ismailia Governorate, Egypt. Land suitability maps are prepared using the Geographic Information System (GIS), and the soil properties are analyzed and evaluated for the different surface, sprinkler, and drip irrigation methods. The results show that the sprinkler and drip irrigation strategies are more practical irrigation methods and additional environment friendly than surface irrigation for enhancing land productivity. Moreover, the principle acumen for creating use of the surface irrigation on this space is for lowering the soil salinity. Land capability index for surface irrigation ranges from 20.5 to 72.2% (permanently not suitable N2 to moderately suitable S2); and the max capability index (Ci) for drip irrigation was 81.3% (highly suitable-S1), while the mean capability index (Ci) was 42.87% (Currently not suitable-NI). The land suitability of the study area using sprinkler irrigation was ranked as highly suitable (S1), moderately suitable (S2), marginally suitable (S3), and currently not suitable (N1). Thus, the obtained data indicated that applying drip irrigation (trickle irrigation) was the most efficient system compared to the sprinkle and surface irrigation systems. To identify the soil, water erosion vulnerability, and soil optimal management strategies for the agricultural parcel in that region, the ImpelERO model (soil erosion vulnerability/impact/management) was applied. Erosion risk classes ranged from V2 (small) to V3 (moderate), that that region categorized as small-sensitive to water erosion by alfalfa, to moderate-sensitive to water erosion by olive. The results of soil losses varied from 7.1 to 37.9 t ha−1 yr−1 with an average of 17.7 t ha−1 yr−1. Thus, guarantee efficient water use and soil suitability for food production in the future will require the use of an efficient irrigation system.

Published: January 2021

Inner-city transportation looms large in big cities in the so-called Global South due to rapid population and urban growth. To tackle this challenge, a Bus Rapid Transit (BRT) system was implemented in Dar es Salaam (Tanzania) in 2016. This paper reports on the results of a pilot study on the impacts of the BRT on city development and livelihoods in Dar. Our pilot study, which is part of the collaborative research project LIPSINDAR (Linking Partners for a Sustainable and Inclusive Dar es Salaam), was not designed to provide a comprehensive insight into the problems of urban planning, infrastructure modification and their impact on urban livelihoods. Rather, using the example of Dar es Salaam, the study served as an entry point to highlight challenges and future research demands in the context of urban insecurities and risks in large cities of the Global South. In particular, our study investigated the BRT as an element of critical infrastructure in Dar es Salaam and probed into its impact on residents’ livelihoods, focusing on the influence of service disruptions on everyday routines, and on different stakeholders’ views on the functionality of the BRT. Elaborating on this topic, interviews, street vendor surveys and mappings were used as methods to describe the processes. To examine the results more closely, the outcome was divided into groups of different fields of activity, namely Traffic Management, Local Residents, City Administration, Basic Provision Services and Street Vendors. In summary, the pilot study confirms that the implementation of the BRT system has, in general, served to improve urban livelihoods. Reducing commuting times and enhancing access to basic services found positive results. There is, however, still potential for improvement: the bus network, in particular, needs to be expanded and the vulnerability to natural extreme events, especially flooding, needs to be addressed.
The Compounded Effects of COVID-19 Pandemic and Desert Locust Outbreak on Food Security and Food Supply Chain
Authors: Xu Zhitao , Elomri Adel , El Omri Abdelfatteh , Kerbache Laoucine , Liu Hui
Published: January 2021

The COVID-19 pandemic and locust swarm outbreaks pose a significant threat to global food systems, causing severe disruptions in both local and international food supplies from farm to fork. The main objective of this study is to understand and identify the disruptions during the crises and create a map of how resilience can be established to recover and sustain the food supply chain (FSC) functions as well as food security. The detrimental impacts of the compound crises on the FSC are explored and the effects of the affected areas are estimated under optimistic and pessimistic scenarios. As a response to the disruption caused by the crisis in FSCs, reactive and proactive solutions are proposed to develop resilience at the food sector level. In the short term, the reactive solutions, consisting of smoothing the food demand, supply and delivery, and food production and processing, can be borrowed. In the long term, the proactive solutions can be conducted by developing multi-level short intertwined FSCs. Our comprehensive investigation of the resilience elements in diverse operations and potential strategies should contribute to the improvement of FSC resilience in the face of ongoing and growing threats.
Are Urban Planning Schools in the Global South Prepared for Current Challenges of Climate Change and Disaster Risks?
Authors: Scholz Wolfgang , Stober Tim , Sassen Hannah
Published: January 2021

This article undertakes an analysis of current urban planning programs at universities with a focus on sub-Saharan English-speaking African (SSA) and South East Asian countries (SEA) as comparison cases. The aim is to identify, as an important part of sustainability, the existence and share of climate change and disaster related courses in the curricula, and to understand to what extent these topics are already integrated into current urban planning programs at the university level and thus shape the knowledge and skills of future urban planners. The local academic and professional environments in which the programs are based are taken into account by a review of the historical development of the programs. The analysis in mid-2020 took only those universities and programs into account that have curricula and course titles available online. The data were analyzed both quantitatively and qualitatively. The second part of the research deals with the discussion of how these courses can be best integrated into the existing curricula and thus serve the adequate education of urban planners by providing some concrete ideas.
Materiality Matrix Use in Aligning and Determining a Firm’s Sustainable Business Model Archetype and Triple Bottom Line Impact on Stakeholders
Authors: Geldres-Weiss Valeska V. , Gambetta Nicolás , Massa Nathaniel P. , Geldres-Weiss Skania L.
Published: January 2021

The materiality matrix is a tool that helps companies understand how the stakeholders’ view of material issues in environmental, social, and economic/governance dimensions influences their value creation process, and creates triple bottom line impacts through shaping their strategic business model elements. Building on the multidimensional definition of materiality, we propose to use the materiality matrix as a tool to aid the transformation of a company’s existing traditional business model into a more sustainable one (inside-out approach), and to enable the identification of the most appropriate business model archetype to incorporate innovation into its sustainable business model (outside-in approach). This paper presents the materiality matrix as a new tool to enhance and transpose a company’s business model towards sustainability—as illustrated through the analysis of the Viña Concha y Toro business model case. This new tool contributes to sustainable business model literature and stakeholder theory by incorporating the materiality matrix as a gateway to business model innovation, and as a tool to explain the dynamics in the sustainable value creation process and concomitant impact on stakeholders.
The Long-Run Impact of Information Security Breach Announcements on Investors’ Confidence: The Context of Efficient Market Hypothesis
Authors: Ali Syed Emad Azhar , Lai Fong-Woon , Hassan Rohail , Shad Muhammad Kashif
Published: January 2021

Information and communication technologies (ICTs) are the cornerstone for sustainable development, but if they are not appropriately managed, they will impede progress towards the United Nations Global Sustainable Development Goals. Among undesirable impacts, emphasis must be put on the risk of information security (ISec) breaches, as they pose a potential threat to businesses there. Especially for publicly traded firms, they could create a long-lasting influence on their financial performance and, thus, stock investors’ confidence. Following the efficient market hypothesis’s footsteps, previous studies have examined only the short-run impact on investors’ confidence ensuing to ISec breach announcements. Therefore, this study investigates the long-run impact of ISec breach announcements on investors’ confidence. Based on a sample of 73 ISec breach announcements during 2011–2019, this paper examines the impact on investors’ confidence, as demonstrated by long-run abnormal returns and equity risk of those firms. Using a one-to-one matched sampling approach, each firm’s performance is analyzed with its control firm over eighteen months, starting six months before the announcement, through twelve months after the announcement. Firms experienced a significant negative abnormal return of 15% to 18% during the twelve months following the breach announcement. In comparison, equity risk increased by 11% within six months before and after an announcement. This study can help investors, managers, and researchers better understand a long-term relationship between ISec breaches and investor confidence in the context of efficient market hypothesis.
Improving Relations between a State and a Business Enterprise in the Context of Counteracting Adverse Effects of the Resource Curse

Published: January 2021

Natural resources play a significant role in the development of the global economy. This refers, in particular, to strategic fuel and mineral resources. Due to the limited supply of natural resources and the lack of substitutes for most of the key resources in the world, the competition for the access to strategic resources is a feature of the global economy. It would seem that the countries which are rich in resources, because of this huge demand, enjoy spectacular economic prosperity. However, the results of empirical studies have demonstrated what is known as the ‘resource curse’. This article concentrates on the characteristics of the paradox of plenty, and in particular on the possibilities of preventing this phenomenon. The aim of this article is to identify the measures of economic policy with which to counteract the resource curse, based on the relationship between the state and the extraction business. Upon the critical analysis of the relevant literature, we concluded that the state’s economic policy, implemented in cooperation with the extraction business, is increasingly important for the prevention of the resource curse. In the context of the resource curse, the optimal and most consensual instrument, in comparison with other resource sharing agreements, is a production sharing agreement (PSA), which should also be adjusted to the current local economic conditions in a given country.
Who Are the Intended Users of CSR Reports? Insights from a Data-Driven Approach
Authors: Lindgren Charlie , Huq Asif M. , Carling Kenneth
Published: January 2021

There is extant research on theorization, conceptualization, determinants, and consequences of corporate social responsibility (CSR). However, what firms include in their CSR or sustainability reports are much less covered and are predominantly covered in case studies of individual firms. In this paper, we instead take a holistic view and simultaneously explore what firms around the globe currently disclose in these reports, more specifically we investigate if firms are shareholder or stakeholder focused. In this investigation, we check the alignment of the reports to the materiality framework of Sustainability Accounting Standards Board (SASB) which was developed having shareholders as the intended user. To estimate what firms disclose in CSR reports we used the unsupervised Bayesian machine learning approach latent Dirichlet allocation (LDA) developed by Blei et al. We conclude that firms target shareholders as the intended users of these reports, even in environments where stakeholder approach of management is argued to be more dominant. Methodologically, we contribute by demonstrating that topic modeling can enhance the objectivity in reviewing CSR-reports.
Effects of Functional Strength Training on Functional Movement and Balance in Middle-Aged Adults
Authors: Guler Ozkan , Tuncel Oguzhan , Bianco Antonino
Published: January 2021

Functional movement deficiencies cause falls and injuries in adults. Functional strength training (FST) is emerging as a new training method for athletes, middle-aged and older adults, to improve functional movement: The present study was conducted in order to investigate the effects of FST on balance and functional movement in healthy and independent middle-aged adults. The sample for this study consisted of 46 physically active individuals (24 female and 22 male). A total of 46 subjects were divided based on randomly into the functional strength training (FST) group (n = 26) aged: 51.55 ± 3.73 years; height: 168.69 ± 8.8 cm; body mass: 75.88 ± 12.18; and traditional strength training (TST) group (n = 20) age: 52.85 ± 4.01; height: 166.9 ± 9.98; body mass: 76.15 ± 10.45. Each group performed 24 sessions of a training protocol three-time a week. The functional movement was assessed using the functional movement screen (FMS) protocol. Balance performance was determined by using the balance error scoring system (BESS). Bodyweight and body fat ratio were measured using bioelectric impedance. There was a significant statistical difference between FMS total scores after an eight-week FST in the FST group. After the intervention, the functional strength group tended to have significantly better balance control than the traditional strength group (p = 0.01). Statistically, significant differences were observed between pre-test and post-test in the intervention group on BMI, body fat, and body mass (p = 0.01). There were not found significant differences in balance control and FMS score in TST group. As a result of this study, FST positively affected the FMS total score and balance performance in middle-aged adults. Early detections of the deficiencies in functional movement and balance in the middle ages may reduce the risk of insufficiency and fall in adults through targeted functional strength training intervention.
The Sustainability of Industrial Heritage Tourism Far from the Axes of Economic Development in Europe: Two Case Studies
Authors: Somoza-Medina Xosé , Monteserín-Abella Obdulia
Published: January 2021

The transformation of mining and industrial spaces into tourist spaces is part of the debate surrounding the profound changes in the contemporary economies of developed European countries. The loss of competitive power of their traditional companies, the obsolescence of many manufacturing facilities, and the take-off of other industrial economies in remote parts of the world have led to the closure of thousands of mines and factories, with the approval of environmental groups. In some privileged places, these ex-industrialized spaces have recovered environmentally, been allocated aid for socio-economic reconversion, and reoriented the old mines and factories (now converted into industrial heritage), towards cultural and tourist uses. The successful examples of Ironbridge, Zollverein or Wieliczka, have created the illusion to managers, owners, and local population of being able to turn almost any ruin of the industrial and mining past into a tourist attraction. Starting in the 1990s, many ex-industrial spaces, which were far from the main urban centres, opted for this tourist transformation as a lifeline to slow down the loss of population and economic activities. Sometime after these projects of industrial tourism, the result can be evaluated with objective data that question the sustainability of the model and the resilience of these places. This paper focuses on questioning the sustainability and resilience of the tourist transformation of two former mining areas located in Spain (Almadén and Sabero), far from the axes of economic development.
Linking the Creative Economy with Universities’ Entrepreneurship: A Spillover Approach
Authors: Lazzaro Elisabetta
Published: January 2021

In recent years the importance of the creative economy has also characterised the international higher-education sector through specialised education, research and entrepreneurship. In this paper I apply and discuss the concept of spillovers as a relevant theoretical framework to understand and foster the value generated by university programs in the creative economy. After introducing the main concepts of spillovers in relation to innovation and growth, I discuss the recent developments in the research on spillovers applied to the arts, culture, and creativity. Through a contextualised model of academic creative economy, the analysis is combined with that on knowledge spillovers in higher education and universities’ third mission, to fill a research gap that still exists in creative economy programs and their potential to generate creative spillovers. The study further integrates some more recent literature on university spillovers, which can provide useful methodological suggestions especially oriented toward internalising and enabling positive creative spillovers, in particular in an urban context.
Rural Resilience in China and Key Restriction Factor Detection
Authors: Li Yuheng , Song Chuanyao , Huang Huiqian
Published: January 2021

Enhancing rural resilience plays an important role in sustaining rural development when certain rural communities’ decline becomes an inevitable process in the world. The paper evaluates China’s rural resilience and investigates the spatio-temporal differences of rural resilience across the country in the period 2000–2018. Theoretical analysis indicates that rural resilience determines how and to what extent rural communities interact with external challenges. Empirical analysis shows a slight increasing tendency of China’s rural resilience that remains below the median level. Rural resilience in Eastern China, which has a developed economy, is higher than that in Central and Western China. Compared with social resilience and engineering resilience, economic resilience is found to be the key restriction factor to China’s rural resilience in the research period. This is mainly attributed to rural laborers’ outflow to cities. The same findings are also seen in China’s three regions. Policy implication emphasizes the importance of prioritizing rural economic growth to realize China’s rural revitalization strategy.
Transformation of the Innovative and Sustainable Supply Chain with Upcoming Real-Time Fashion Systems
Authors: Lee Yoon Kyung
Published: January 2021

Technologies that are ready-to-use and adaptable in real time to customers’ individual needs are influencing the supply chain of the future. This study proposes a supply chain framework for an innovative and sustainable real-time fashion system (RTFS) between enterprises, designers, and consumers in 3D clothing production systems, using information communication technology, artificial intelligence (AI), and virtual environments. In particular, the RTFS is targeted at customers actively involved in product purchasing, personalising, co-designing, and manufacturing planning. The fashion industry is oriented towards 3D services as a service model, owing to the automation and democratisation of product customisation and personalisation processes. Furthermore, AI offers referral services to prosumers or/and customers and companies, and proposes individual designs with perfect styles and measurements using new 3D computer aided design and AI-based product design technologies for fashion and design companies and customers. Consequently, 3D fashion products in the RTFS supply chain are entirely digital, saving time and money with sampling and tracking capabilities, secured, and trusted with personalised service delivery.
Preliminary Recognition of Geohazards at the Natural Reserve “Lachea Islet and Cyclop Rocks” (Southern Italy)

Published: January 2021

In this study, we present a preliminary recognition of geohazards at the natural reserve archipelago “Lachea Islet and Cyclop Rocks” by integrating infrared thermography (IRT) and morphological-aerial interpretation. The study area, located in the wider setting of the UNESCO (United Nations Educational, Scientific and Cultural Organization) World Heritage Mount Etna (eastern Sicily), is a worldwide renowned tourist destination suffering from a limited fruition due to the instability of rock masses. The peculiar setting of the area, represented by steep sea rocks and an islet, requires the employment of remote surveying methodologies for the preliminary slope characterization in the perspective of safe ground surveys. In this paper, IRT analysis allowed the recognition of signs of past rockfalls, as well as the presence of loose rock material likely laying in unstable conditions, thanks to the variation of the surface temperature characterizing the slope. The combination of IRT outcomes with morphological-aerial data allowed recognizing the potential source areas of future rockfalls, which were modeled through trajectory simulations. Results showed that a relevant strip of sea surrounding the studied sea rock could be crossed by falling blocks, suggesting the need of instituting a forbidden area for a safe fruition of the reserve. Furthermore, IRT allowed for the recognition of some peculiar features linked to the presence of tectonic lines. Such correspondence was validated by a comparison with literature structural data, proving the potential of such remote methodological approach. This represents a new aspect of the application of IRT to other fields of geosciences, thus representing a starting point for the scientific development of new technological branches.
Attitudes and Behaviours of Certified Winegrowers towards the Design and Implementation of Biodiversity Farming Strategies
Authors: McWilliam Wendy , Wesener Andreas
Published: January 2021

Substantial environmental impacts and loss of resilience occurs with conventional vineyard designs characterized by monotonous specialized production. Studies support the restoration of green infrastructure (GI) and introduction of other production systems as promising biodiversity design strategies. However, little is known about the degree to which winegrowers are implementing them. We surveyed Willamette valley, Oregon, certified sustainable winegrowers as potential early adopters of innovative biodiversity design strategies. Results revealed growers were implementing up to 11 different types of GI components, providing them with up to 16 different ecosystem services, and six disservices. The GI was implemented at three spatial scales, with growers pursuing a sharing GI design strategy at fine scales, and a sharing and sparing strategy at intermediate and farm-wide scales. Only biodynamic certified farmers had implemented valued additional production systems. Growers can improve the implementation of their biodiversity GI designs by adopting an integrated multi-system whole farm design approach. Key enablers for grower implementation of GI and/or additional production systems included: (1) Grower awareness and value of strategy’s ecosystem services and functions, (2) grower knowledge of their design and management, (3) certifier requirements for GI, (4) availability of land incapable of growing quality grapes, (5) availability of GI backup systems in case of failure, (6) low risk of regional pest outbreaks, (7) premium wine prices, and (8) strong grower environmental and cultural heritage ethics. Further research is required to identify effective ways to advance these enablers among growers, and within certification and government programmes, to improve the implementation of these strategies among growers.
How Much Can Carbon Taxes Contribute to Aviation Decarbonization by 2050
Authors: Valdés Rosa Maria Arnaldo , Comendador Victor Fernando Gomez , Campos Luis Manuel Braga
Published: January 2021

Aviation emissions from 2016 to 2050 could consume between 12% and 27% of the remaining carbon budget to keep global temperature rise below 1.5 °C above preindustrial levels. Consequently, aviation is being challenged to immediately start to reduce its in-sector emissions, then sharply reduce its CO2 emissions and fully decarbonize toward the second half of this century. Among the analyses carried out within the Horizon 2020 project PARE—Perspectives for Aeronautical Research in Europe, this paper tackles the potential role of climate change levy schemes in achieving the ambitious objective of aviation decarbonization by the year 2050.
Improved Vulnerability Assessment Table for Retaining Walls and Embankments from a Working-Level Perspective in Korea
Authors: Lee Jaejoon , Lee Hyunji , Yun Hongsik , Kang Chol , Song Moonsoo
Published: January 2021

Climate change can lead to unpredictable slope collapse, which causes human casualties. Therefore, Korea has devoted significant effort to the management of slope disasters. The Ministry of the Interior and Safety of Korea, which oversees the safety of the nation’s people, has allocated a four-year budget of $557 million to investigate, assess, and maintain steep slope sites. However, there have been fatalities caused by steep slope site evaluations based on inadequate knowledge and a single retaining walls and embankments (RW&E) assessment table. Therefore, the assessment table for RW&E-type steep slopes needs to be improved in terms of its accuracy, simplicity, and ease of use. In this study, domestic and global evaluation methods were reviewed, problems associated with the existing RW&E assessment table were identified, and a focus group interview was conducted. The RW&E assessment table was improved through an indicator feasibility survey and analytic hierarchy processing. The improved assessment table was categorized from one to four classifications to reduce the ambiguity of the evaluation: concrete, reinforced soil-retaining walls, stone embankments, and gabions. This study will provide the sustainability of slope safety and serve as a reference for classification and evaluation criteria across all national institutions that conduct RW&E evaluations.
Earthen Plasters Stabilized through Sustainable Additives: An Experimental Campaign
Authors: Rescic Silvia , Mattone Manuela , Fratini Fabio , Luvidi Loredana
Published: January 2021

The earthen architecture widely spread in many countries of Europe, America, Asia, Africa, testifies to a particular material and immaterial culture. Nevertheless, it is a fragile heritage, which needs continuous maintenance. To encourage the preservation of such evidence of building techniques, an experimental campaign aimed at the development and evaluation of the performances of protective earthen plasters was undertaken. The durability of the plasters was improved through the addition of different additives, some of them traditional (such as lime and gypsum) and others innovative (geopolymers, enzymes), and resulting from industrial wastes (cement kiln dust). These additives have been selected considering low production costs and a reduced environmental impact, to improve the sustainability of the interventions. The performances of the earthen plasters in terms of efficacy (resistance to water erosion, water absorption, drilling, thermo-hygrometric cycles) and compatibility (changes in color and water vapor permeability) have been evaluated. Good performances were obtained by the different mixtures and, in particular, by those stabilized with gypsum. The results of this experimentation could find a useful application in the preservation of both ancient and new earthen built heritage.
Implementing Concurrent Engineering and QFD Method to Achieve Realization of Sustainable Project
Authors: Rihar Lidija , Kušar Janez
Published: January 2021

In this paper, we present the impact of concurrent engineering strategies, methods, and tools on product sustainability. Concurrent engineering can be used to achieve the primary goals of a product realization project: lower costs, shorter times, high quality, and increasing value. Currently, it is important that new products also meet product sustainability goals, such as economic, environmental, and social goals. The sustainability of a product can be influenced the most in the early stages of product development, so in this paper, we present a customized quality function deployment (QFD) method called the house of sustainability, which translates sustainability requirements into technical solutions for a product. A seven-step process for implementing a sustainable product realization project is also proposed, in which the house of sustainability is one of the most important tools. The proposed process is illustrated with an example of a concurrent product realization project in engineering to order production.
Are Farms Located in Less-Favoured Areas Financially Sustainable? Empirical Evidence from Polish Farm Households
Authors: Pastusiak Radosław , Soliwoda Michał , Jasiniak Magdalena , Stawska Joanna , Pawłowska-Tyszko Joanna
Published: January 2021

The topic of farms that deal with environmental constraints is an ongoing agricultural policy issue, including within the Common Agricultural Policy. We propose empirical evidence based on a sample of Farm Accountancy Data Network (FADN) farm households, evaluate the influence of chosen factors on financially sustainable farm development and verify less-favoured area (LFA) farms’ growth compared with non-LFA households. To specify farm households, we use the Sustainable Growth Challenge (SGC) model and DuPont decomposition based on financial measures and indicators that were adopted from corporate finance. It is concluded that the differences in SGC and revenue growth values between LFA and non-LFA farms mainly results from the system of subsidising LFA farms that receive compensation for farming in areas with adverse environmental conditions. Generally, the impact of agricultural policies on LFA and non-LFA farms is significant and may weaken the effect on LFA. With the exception of education, other sociodemographic factors do not highly influence farm efficiency. Along with improvements in the quality of human capital (e.g., higher education level), awareness of subsidies, and debt and innovative solutions increases. The interest in precision agriculture and agriculture 4.0 is also growing, which directly translates into better technological and financial efficiency of farms.

Published: January 2021

In the context of global changes, nature-based solutions (NBSs) increasingly draw attention as a possible way to reduce disaster risk associated with extreme hydro-meteorological events while providing human well-being and biodiversity benefits at the same time. The PHUSICOS platform is dedicated to gather and analyse relevant NBSs used to reduce disaster risk associated with extreme hydro-meteorological events in mountainous and hilly lands. To design the platform, an in-depth review of 11 existing platforms has been performed. The PHUSICOS platform currently references 152 literature NBS cases and is continuously enriched through the contribution of NBS community. The platform also proposes a qualitative assessment of the NBSs collected according to 15 criteria related with five ambits: “disaster risk reduction”, “technical and economical feasibility”, “environment”, “society”, and “local economy”. This paper presents the structure of the platform and a first analysis of its content.
Cooling Effect of Different Land Cover Types: A Case Study in Xi’an and Xianyang, China
Authors: Ma Yuhe , Zhao Mudan , Li Jianbo , Wang Jian , Hu Lifa
Published: January 2021

One of the climate problems caused by rapid urbanization is the urban heat island effect, which directly threatens the human survival environment. In general, some land cover types, such as vegetation and water, are generally considered to alleviate the urban heat island effect, because these landscapes can significantly reduce the temperature of the surrounding environment, known as the cold island effect. However, this phenomenon varies over different geographical locations, climates, and other environmental factors. Therefore, how to reasonably configure these land cover types with the cooling effect from the perspective of urban planning is a great challenge, and it is necessary to find the regularity of this effect by designing experiments in more cities. In this study, land cover (LC) classification and land surface temperature (LST) of Xi’an, Xianyang and its surrounding areas were obtained by Landsat-8 images. The land types with cooling effect were identified and their ideal configuration was discussed through grid analysis, distance analysis, landscape index analysis and correlation analysis. The results showed that an obvious cooling effect occurred in both woodland and water at different spatial scales. The cooling distance of woodland is 330 m, much more than that of water (180 m), but the land surface temperature around water decreased more than that around the woodland within the cooling distance. In the specific urban planning cases, woodland can be designed with a complex shape, high tree planting density and large planting areas while water bodies with large patch areas to cool the densely built-up areas. The results of this study have utility for researchers, urban planners and urban designers seeking how to efficiently and reasonably rearrange landscapes with cooling effect and in urban land design, which is of great significance to improve urban heat island problem.
Performance Evaluation of Sheltered Workshops. Does Legal Status Matter?
Authors: López-Penabad María-Celia , Maside-Sanfiz José Manuel , Torrelles-Manent Juan , López-Andión Carmen
Published: January 2021

Social enterprise pursues both social and economic goals and is recognized as a formula for achieving sustainable development. Sheltered workshops (SWs) are a manifestation of this phenomenon, their main objective being the labor market integration of disabled people. In this paper, the efficiency of SWs has been studied taking into account the operational and the core social aspects, as well as their distinct nature, namely for-profit or non-profit status. Additionally, we have analyzed the relationship between the social efficiency and the economic returns of these entities. To do this, a semiparametric methodology, combining different data envelopment analysis (DEA) models with truncated regression estimation has been used. It is the non-profit and top-performing SWs that achieve the best social and economic efficiency. For-profit and low-performing SWs show further reductions in social efficiency as a result of the economic crisis and uncertainty in subsidy-related public policies. Their extensive social proactiveness and high economic strength in the crisis period positively influenced their social and economic efficiency. We have also proven that it is the most profitable SWs that have the greatest social efficiency. We consider that our results constitute a useful complement to other evaluation models for social enterprise.

In this study, we present a novel method of detecting hard hat use on construction sites using a modified version of an off-the-shelf wearable device. The data-transmitting node of the device contained two sensors, a photoplethysmogram (PPG) and accelerometers (Acc), along with two modules, a global positioning system (GPS) and a low-power wide-area (LoRa) network module. All the components were embedded into a microcontroller unit (MCU) in addition to the power supply. The receiving node included a server that displayed the results via both the Internet of Things (IoT) and smartphones. The LoRa network connected two nodes so that it could function in larger areas such as construction sites at a relatively low cost. The proposed method analyzes the data from a PPG sensor located on the hard hat chin strap and automatically notifies a manager when a worker is not wearing the required hard hat at the site. In addition, by utilizing the PPG sensor data, a heart rate abnormality-detecting feature was added based on an age-adjusted maximum heart rate formula. In validation tests, various PPG sensor locations and shapes were studied, and the results demonstrated the smallest error in the circular shaped sensor located at the upper neck (0.56%). Finally, an IoT monitoring page was created to monitor heart rate abnormalities while identifying hard hat use violations via both PCs and smart phones.

Egypt, akin to many countries in the global South, has striven to promote collective management to overcome the challenges of irrigation management since the 1990s. Establishing shared pumping stations (SPSs) has been one of the cornerstones helping farmers better manage water for irrigation. Operating SPSs successfully poses collective action problems, for which there is no single set of solutions. This paper utilizes fuzzy set qualitative comparative analysis (fsQCA) to identify which conditions or configurations are sufficient or necessary for well-operated SPSs. The study draws on empirical data gathered through semi-structured interviews from 45 cases, located in Kafr El-Sheikh Governorate in Egypt’s Nile Delta. Results show that three different paths are sufficient to ensure well-operated SPSs. These are: (1) the condition of effective rules related to allocation, monitoring, and sanctions; (2) the configuration of small group size of SPSs and large irrigated sizes of SPSs; or (3) the configuration of adequate water supply and appropriate location of the SPS command area. The paper concludes that neither group size nor resource size alone explains the outcome of collective action, while a combination of both factors does. Similarly, an adequate water supply is essential to enhance users’ engagement in collective actions only when resource location characteristics do not provide alternative water sources for irrigation.
Investigating the Spatial Heterogeneity and Correlation Network of Green Innovation Efficiency in China

With environmental problems becoming increasingly serious worldwide, scholars’ research views on innovation have begun to pay more attention to the technological value from an ecological perspective, instead of simply analyzing the importance of technological innovation from the perspective of economic value. Currently, improving green innovation efficiency (GIE) has been considered as a critical path to realizing economic transformation and green development. Based on the global Super-Epsilon-based measure (EBM) model, Moran index, vector autoregression (VAR) model, and block model, this study investigated the temporal and spatial characteristics of GIE in 30 provinces in China from 2009 to 2017, and analyzed the spatial heterogeneity and spatial correlation network characteristics. The results showed that in spatial terms, China’s GIE presented an extremely unbalanced development model. In provinces with a higher GIE, there was an overall improvement of GIE, but there was a lower impact in provinces with a lower GIE. The efficiency of China’s green innovation could be divided into four blocks. The first block was the main overflow, the second block was the broker, the third block was the bilateral spillover, and the fourth block was the net benefit. The four blocks had their own functions, and a very significant correlation was observed among them.

The effectiveness of the audit is conditioned by the systematic nature of the analyses and their periodicity. In this respect, the work of internal auditors must be coherent, continuous, and professional. These conditions can be met only if the activity is organized as a permanent system, which has its objectives and has resources (human, material, and financial), as well as adequate tools (audit method) corresponding to the activities carried out within the hydro-construction companies. The methodology for assessing the occupational safety status specific to companies in the field of hydrotechnical constructions was tested at the economic operators within SC HIDROCONSTRUCȚIA SA Bucharest. Thus, from the observation made based on the two calculation formulas’ application, it can be appreciated that the weighted amount more clearly and objectively reflects the existence of problems in achieving safety and health at work, thus constituting the result of a cautious approach, as opposed to the arithmetic mean formula, which leads to a result that tends to overestimate the value of the assessment. Additionally, the security risk determination in the field of occupational security at the economic operators was performed, according to the procedure of applying the method, based on the Gumbel probability function associated with insecurity, and the accuracy of various estimates on risk predictors was ensured by using the Kolmogorov–Smirnov statistical verification test in order to determine the confidence interval of the forecast results.
