Published: March 2022

Sialyloligosaccharides (SOS) are bioactive molecules that play an important role in brain development and the increase in immunity in infants. In adults, they act as prebiotics, enhancing protection against microbial pathogens. In the present work, we aimed to analyze the levels of SOS in mature milk, at days 60 and 120 after calving in four cow breeds: Holstein (HO), Simmental × Holstein (SM × HO), Simmental (SM), all fed with total mixed ration (TMR) in intensive production, and Podolica (POD) raised on pasture in an extensive system. The concentrations of SOS (3′-sialyllactose = 3′-SL, 6′-sialyllactose = 6′-SL, 6′-Sialyl-N-acetyllactosamine = 6′-SLN, disialyllactose = DSL, expressed in mg/L) were determined using HPAEC-PAD, a high-performance anion-exchange chromatography with pulsed amperometric detection. Results showed both breed and lactation effects. The contents of 3′-SL, 6′-SL, 6′-SLN, and DSL were higher at 60 than 120 days (p < 0.001), as well as in POD, as compared to the other breeds (p < 0.001). Furthermore, SM showed a significantly greater level of 3′-SL than HO (p < 0.001), as well as a significantly higher level of 6′-SLN in SM than HO (p < 0.001) and SM × HO (p < 0.001). Our findings may have implications for several areas of sustainability that might be used in the cattle management system.

Published: March 2022

Land is a main factor in food production, and cultivated land resources provide opportunity for the national food security. This study empirically estimates the impact of farmland protection on the security of grain supply in major grain-producing areas of China. For this purpose, from 2010 to 2019, panel data was collected from 13 main grain-producing provinces of China. The results revealed that the protection of cultivated land resources in the main grain-producing areas with direct means, incentives, and technological progress, significantly and positively impacted the security of grain supply. Furthermore, a mismatch was found between resource conditions and their use for grain production in the Northern region, and the lack of protection of cultivated land resources in the Southern region, which leads to the insignificant positive promotion of grain supply security. The results of the study strongly suggest that central and national governments of China need to provide a proper policy for the protection of cultivated land resources with equal emphasis on quantity, quality, and sustainability to ensure food security.

Rapid urbanization in Pakistan is triggering regulated and unregulated land cover changes in planned and semiplanned urban areas. The key objective of this study is to assess the spatial–temporal fluctuations in the land use/land cover (LULC) transformations in planned (Islamabad) and semiplanned (Rawalpindi) urban areas over the last forty years (1976–2016). The study focuses on the orientation of LULC modifications and analyzes concomitant impacts on urban environmental sustainability. Therefore, remotely sensed data were retrieved and processed through Google Earth Engine (GEE) by applying supervised classifier algorithms on each of the five chosen Landsat images. The trajectory of LULC changes for each of the four periods 1976–1988, 1988–1995, 1995–2006 and 2006–2016 was critically scrutinized. The observations revealed massive physical expansions and LULC convergences during these timeframes. The proportionate share of built-up surfaces in this contextual setting substantially stretched from 0.83% in 1976 to 23.23% in 2016, while the shares of cropland and shrubberies significantly reduced. The orientation and magnitude of such changes were observed asymmetrically in the adjoining urban settlements. The assessments formulate that availability of land for urban growth, urban planning and regulatory control significantly determines the speed, scale and orientation of urbanization in planned and semiplanned areas. The study substantiates the notions that the efficient use of cost-effective remotely sensed data offers a pragmatic and reliable tool for assessing, evaluating and monitoring urban land resources. The inferences and insights are relevant for urban and regional planners as well as for other scientific communities.

Published: March 2022

Biological management techniques act as a promising and sustainable alternative to alleviate pathogen-induced losses, improve ecosystem functions, and reinforce the resilience of agricultural systems. Lebanese squash production has been threatened by powdery mildew disease caused by the fungus Podosphaera xanthii. Very few studies, even unpublished ones, stress the evaluation of biological control approaches in the Lebanese agriculture sector. Here, we have aimed to evaluate the effect of five safe biological treatments (olive soap, sodium bicarbonate, garlic extract, horsetail, and compost tea) in the management of powdery mildew on Lebanese squash in organic open field conditions. Plants were treated after the first spots of powdery mildew appeared on leaves. We then examined the leaves to evaluate disease incidence and severity, and to compare the ability of the five treatments to reduce powdery mildew disease and incidence, in comparison with the untreated control. Plants treated with sodium bicarbonate and garlic extract were the least affected by powdery mildew regarding disease incidence and severity, while tea compost proved to be the least effective product. Organic management of vegetable crops is extremely important in order to ensure global food security and reduce pesticide applications.

Published: March 2022

This paper takes the old district of the east Huan Shi Road area in the Yuexiu District, Guangzhou City, as an example. Through field research, resident visits, and expert interviews, the secondary and tertiary indicators in the measurement framework were obtained by combining six years of living experience. The questionnaire was designed through the relationship between the indicators, and a small sample test was conducted to test the results before generating the final questionnaire. The questionnaires were distributed both online and offline, and the data were analysed in conjunction with the Kano model; then, the results were compared with the field research. Based on the perspective of living experience, a sustainable renewal strategy is proposed for the renovation of old neighbourhoods in practice.

Published: March 2022

The aim of the work was to evaluate the safety of bee drone brood in terms of the risk of possible contamination with heavy metals, microbial contamination, and sensory acceptability. Bee drone brood dried at a temperature of 80 °C in a hot air oven (DBO) and lyophilized drone brood (DBL) were used. Sensory evaluation was performed on an oatmeal ball (O-B) and drone brood ball (DBO-B). For the determination of the minerals and other elements in DBO, spectrometric analysis was used. The content was as follows: Fe 60.87 µg/g, Cu 54.83 µg/g, Zn 257 µg/g, Ag 82.7 µg/g, Pb 2.1 µg/g, Au 1.2 µg/g, Ca 1336 µg/g, Sr 3.13 µg/g, Zr 1.67 µg/g, Bi 3.87 µg/g, Br 1.95 µg/g. The detected content of lead in dry matter (2.1 µg/g) was high above the limit set for crustaceans (0.4 µg/g). By comparing microbial assay values, no statistically significant difference between freshly dried DBO and dried DBO after a month of storage was detected. Bee drone brood contains microbes far below the legal limits and it is a good source of calcium, iron, and zinc. Except for the juiciness, consumers rated O-B better than DBO-B. A statistically significant difference (p < 0.05) was found only in taste.

Published: March 2022

A large majority of Swedish children do not reach the recommended daily activity level. Some, but not all, studies show that extra physical activity may have positive effects on children’s school performance, physical fitness and health. The present purpose was to offer pupils from the 7th to the 8th grade extra aerobic exercise led by physical education teachers and to evaluate the effects on aerobic fitness, muscle strength, school grades and health. The hypothesis was that extra aerobic exercise would improve physical fitness, school grades and health. In the two-year project, 122 pupils aged 13–14 years from three schools constituted an aerobic group with 30 min extra exercise sessions (≥70% maximal heart rate) twice weekly. A control group of 26 pupils was included. All 148 pupils also had regular 60 min physical education lessons (2/week). A moderate to large significant effect size (via partial eta-squared) of the interaction effect for the aerobic group compared to the control group over time was generally seen for aerobic fitness, the muscle strength test with push-ups, school grades in Swedish, English and physical education, and in average school grade for four school subjects combined, thus also including mathematics. Within the aerobic group, significant improvements were also shown for aerobic fitness, endurance and strength of abdominal and leg muscles, and the total physical test index during the two-year project. The control group showed no corresponding improvement in these parameters. Improvements in school grades were generally seen among both sexes in the aerobic group, whereas improvements in physical capacity were distinctly more pronounced among boys and seldom among girls. A similar pattern with significant improvement in several school grades was noted in all three intervention schools, although one of the schools had a distinctly larger proportion of children who immigrated to Sweden. The aerobic group showed significantly higher ratings (with a small to moderate effect size) on several questions about physical self-perception than the control group at the end of the 8th grade. This teacher-led school intervention generated a sustainable project with improvements in physical fitness and school grades. The project might act as an inspiration for other schools to increase physical activity to improve physical fitness and possibly school grades.
Relationship between Related Party Transactions and the Social Contribution Activities of South Korean Chaebol Companies
Authors: Ryu Haeyoung , Chae Soo-Joon
Published: March 2022

Corporate social responsibility (CSR) encompasses activities through which a firm ultimately achieves sustainable management by improving the society and environment. Contrary to the general perception that CSR activities can improve only the enterprise value (EV), they can also be strategically deployed based on agency problems (situational factors). Specifically, by focusing on the nature of related party transactions that exhibit high tendencies to introduce agency problems, this study analyzes whether South Korean firms that engage in such transactions perform CSR activities more actively than those that do not. The empirical analysis reveals that firms that engage in related party transactions exhibit increased CSR activity scores, indicating that managers are more likely to deploy CSR activities as a tool for managing their image and concealing or embellishing illicit corporate transactions. Hence, CSR activities undertaken at the expense of shareholders may be opportunistically exploited as a tool for positively embellishing a firm’s image. However, it is observed that chaebol companies do not strategically exploit CSR activities, despite being engaged in related party transactions. Thus, chaebol companies that are registered with a large business group and under the supervision system of the government are unlikely to opportunistically exploit CSR activities.

Authors: Rafiq Farrukh , Chishty Syed Khusro , Adil Mohd
Published: March 2022

Recently, researchers have been drawn to the literature surrounding positive psychology. The role of explanatory and dispositional optimism in eco-friendly tourism has been largely ignored by researchers, even though positive psychology, or optimism, has been studied in the sustainability domain. The purpose of this study is to determine which trait predicts eco-friendly tourist behavior. In the study, the data were collected online using Amazon Mechanical Turk from 400 respondents, and the model was assessed using partial least squares structural equation modeling. Findings revealed that in terms of predicting eco-friendly tourism behavior, dispositional optimism outperformed explanatory optimism. Furthermore, this study found that environmental concern positively moderates the association between optimism (dispositional and explanatory) and eco-friendly tourism behavior. This study has wide-ranging implications for tourism managers, practitioners, and academics.

Authors: Jang Gye-Eun , Cho Gu-Young
Published: March 2022

In this study, 3D-printed polymer bipolar plates were fabricated and applied to the polymer electrolyte membrane fuel cells (PEMFCs). In order to overcome the poor electronic conductivity of polymer bipolar plates, silver current collecting layers were deposited using a sputter process. Influences of the thickness of the current collecting layer were carefully investigated to optimize the thickness. Using a sputter process, current collecting layers were successfully deposited without clear evidence of defects. Additionally, the increment in the total weight of bipolar plates was minimized. The average thickness of the silver current collecting layer was varied from 216 nm to 1.46 um. The results showed the fuel cell with 1.46 um thick Ag current collecting layer coated 3D printed bipolar plates achieved 0.96 V of the open circuit voltage and 308.35 mW/cm2 of performance at 25 °C.

Authors: Shang Haiyang , Fan Jiaojiao , Fan Bingjie , Su Fang
Published: March 2022

In order to achieve the sustainable development of ecological resources and social economy in the Shiyang River Basin, a series of Ecological Compensation policies have been implemented in the basin. This study takes these policies as an opportunity to design an experiment. The nine counties (districts) affected by these policies are used as the experimental samples, and the period from 2000 to 2019 is the experimental period. The difference-in-differences method is used to study the effect of the series of Ecological Compensation policies in the Shiyang River Basin on the economic development of the basin. Furthermore, the regression discontinuity design was used to estimate the time and mechanism of this effect. The research found that the early start of phase I of the Key Governance Planning Project in 2006 played a significant and continuous promotive role in the economic development of the river basin; the Water Resources Allocation and Regulation Plan significantly promoted the development of tertiary industry in 2005–2007; the Key Governance Planning significantly promoted the development of primary industry in 2007–2010. The results suggest that to optimize the industrial structure to the maximum extent in the future and promote the sustainable development of ecological resources and social economy in the Shiyang River Basin, economic changes, such as water-saving green agriculture and eco-tourism, should be developed.
Impacts of Energy Price on Agricultural Production, Energy Consumption, and Carbon Emission in China: A Price Endogenous Partial Equilibrium Model Analysis
Authors: Ma Yongxi , Zhang Lu , Song Shixiong , Yu Shuao
Published: March 2022

Energy market volatility will have systemic effects on agricultural production, energy consumption and carbon emissions. This paper aims to evaluate the impacts of energy price on agricultural production, energy consumption, and carbon emission in China. To achieve the objective, this paper, firstly, constructed a price endogenous partial equilibrium model, and then designed four scenarios of energy price fluctuations, finally evaluating the impacts of energy price fluctuations on agricultural production and its energy consumption and carbon emission. The results revealed that: (1) The impacts on agricultural production are very limited, but higher energy price will result in producers’ welfare loss by 0.6% to 1.4%, under different scenarios. (2) Energy price drives negative impacts on agricultural energy consumption and carbon emission, 1.6%/3.2% and 1.3%/2.6%, respectively, in low/high amplitude scenarios. (3) Heterogeneous impacts are confirmed in the regional analysis; South China is simulated to be the most sensitive area. To mitigate the impacts from energy price and reduce carbon emission in agriculture, several policy implications have recently been proposed, including strengthening supervision of the energy market, constructing an energy saving price-setting mechanism, launching policy instruments to improve energy efficiencies and facilitate cleaner farming techniques, and formulating specific measurements of energy saving and emission reduction for different regions.

Published: March 2022

Land use change and demographic factors directly or indirectly affect ecosystem services value, and the analysis of ecosystem services contributes to optimization of land planning, which is essential for regional sustainable development. In this study, ArcGIS 10.2, IDRISI 17.0 Selva and MATLAB software, value coefficient method, CA-Markov prediction model and population growth model were applied to analyze the spatial and temporal changes of land use trends and ecosystem service values in Guanzhong region, and further predict the impacts of land type changes and population changes on ecosystem services in the context of urbanization. Results showed that the expansion of construction land was the most intense, and the transfer process mainly crowded out arable land; the total ecosystem services value grew spatially in a “low center-high periphery” ring with large differences at the bottom, and forest land was the most important value provider. The total ecosystem services value was estimated to decline in the future, with low-value areas spreading northward and differences in the per capita ecosystem services value increasing. This study provides a reference for optimal simulation of urban expansion and ecological conservation.
Concentration of Microplastics in Road Dust as a Function of the Drying Period—A Case Study in G City, Korea
Authors: Kang Heejun , Park Saerom , Lee Bokjin , Kim Ilho , Kim Seogku
Published: March 2022

Microplastics (MPs) are plastic particles < 5 mm in diameter, which are detected in air, soil, and water, causing various environmental problems. In total, 37.3% of MPs are generated from point pollution sources and 62.7% from non-point sources; most of the non-point-source MPs are from vehicles tires, road-marking paint, and bitumen used in road pavements. In this study, the concentrations of MPs generated from roads in Goyang city, South Korea, were examined in terms of the drying period (0, 1, 2, or 3 d). Road dust sampling was performed at the kerb and quantitative and qualitative analyses were conducted for each sample. The MP concentrations were 552 (±39) MPs g−1 for a 0 d drying period and 1530 (±602) MPs g−1 for a 3 d drying period, confirming that the MP concentration in road dust increased with the increase in drying period. Among the detected substances, black particles accounted for the highest proportion (72%) and were found to be bitumen and tyre particles. This study also confirmed that the MPs accumulated on roads were washed away when rainfall exceeded a certain amount.

Published: March 2022

Groundwater historically has been a critical but understudied, underfunded, and underappreciated natural resource, although recent challenges associated with both groundwater quantity and quality have raised its profile. This is particularly true in the Laurentian Great Lakes (LGL) region, where the rich abundance of surface water results in the perception of an unlimited water supply but limited attention on groundwater resources. As a consequence, groundwater management recommendations in the LGL have been severely constrained by our lack of information. To address this information gap, a virtual summit was held in June 2021 that included invited participants from local, state, and federal government entities, universities, non-governmental organizations, and private firms in the region. Both technical (e.g., hydrologists, geologists, ecologists) and policy experts were included, and participants were assigned to an agricultural, urban, or coastal wetland breakout group in advance, based on their expertise. The overall goals of this groundwater summit were fourfold: (1) inventory the key (grand) challenges facing groundwater in Michigan; (2) identify the knowledge gaps and scientific needs, as well as policy recommendations, associated with these challenges; (3) construct a set of conceptual models that elucidate these challenges; and (4) develop a list of (tractable) next steps that can be taken to address these challenges. Absent this type of information, the sustainability of this critical resource is imperiled.
Exploratory Spatial Analysis of Social Vulnerability and Forest Fire Risk in the Pinhal Interior Sul (Central Portugal)
Authors: Farinha Joana , Cunha Lúcio , Dimuccio Luca Antonio
Published: March 2022

Mainland Portugal is a Mediterranean country, particularly known for the recurrence of forest fires in terms of burnt areas, losses, and damage. The central Portugal administrative area has been in a “stage” of prominence for this dangerous phenomenon, with the sub-region Pinhal Interior Sul being one of the most critical territories. In addition to the manifestation of the dangerous process itself, it is important to state the importance of vulnerability, which has been relatively ignored in the definition of public policies in terms of spatial planning. Vulnerability concerns the way people and their assets are exposed to forest fires (as they represent the main targets of their harmful consequences), as well as how they are affected by, resist, and recover from them. This paper investigates only one of the components of vulnerability—social vulnerability—in terms of demographic, cultural, socio-economic, and infrastructural conditions to establish a comparative analysis among the parishes of the sub-region Pinhal Interior Sul (in particular, between the more urban and rural ones in each municipality). In the studied area, the high values of social vulnerability reinforce the high hazard level. At the municipality level, it is possible to conclude that the population living in more markedly rural and peripheral parishes is more vulnerable to forest fires than those living in the more urban conditions.

Authors: Lin Pei , Chen Lili , Luo Zeshun
Published: March 2022

Most studies on wetland parks focus on resource surveys and evaluations, park planning and design, and the construction of hardware facilities. Only a few studies have covered tourism experiences. With the rapid development of online media, online text data have become a prominent research direction for tourism experiences. Based on the web text analysis method and importance-performance analysis, Rost Content Mining 6 software was used. This served to analyze word frequency, semantic web analysis, and sentiment analysis, and to explain the web text about Haizhu National Wetland Park. It also helped to find problems experienced by tourists and their underlying reasons and proposed improvement strategies. The results showed that the overall quality of the tourism experience in Haizhu National Wetland Park was relatively high. However, some of the negative comments mainly focused on the lack of humanistic landscape construction, lagging infrastructure, and poor management services. By combining research results, improvement strategies were proposed that addressed infrastructure, management services, scenic spot publicity, ecological environmental protection, and so on. These could help to enhance tourism experiences.
Data Integration Analysis Indicates That Soil Texture and pH Greatly Influence the Acid Buffering Capacity of Global Surface Soils
Authors: Wei Hui , Yang Jiayue , Liu Ziqiang , Zhang Jiaen
Published: March 2022

Soil acidification is a global environmental issue that decreases soil functions, and it has been significantly accelerated by anthropogenic activities in recent decades. Soils can resist acidification upon receiving acid inputs due to the resistance or/and resilience capacity of soils, which is termed the acid buffering capacity of soils, and it is often indicated by the soil pH buffering capacity (pHBC). An increasing number of studies have been conducted to quantify soil pHBC at various sites, but to date, integration of global data is lacking; therefore, the variations in large-scale soil pHBC and the factors that influence these variations are still unclear. In this study, we collected previously published data on soil pHBC to analyze its variations on a large scale, as well as investigate the underlying factors influencing these variations. The results showed that soil pHBC varied substantially from site to site, with a mean of 51.07 ± 50.11 mmol kg−1 pH−1. Soil texture and pH, separately or collectively, explained a considerable proportion of the total variation of global soil pHBC. It is well-established that a series of processes contribute to the soil acid buffering capacity in different pH ranges, and the global data analyses showed that pH 5.5 could be a key threshold value; different buffering systems may be active at pH > 5.5 and pH < 5.5. Moreover, tropical soils were more acid-sensitive than temperate and subtropical soils, and forest soils had significantly lower soil pHBCs than grassland and cropland soils. This could be attributed in part to the different soil properties, such as soil texture or pH, among the different climatic zones and ecosystems.
Circular Economy and Financial Aspects: A Systematic Review of the Literature
Authors: Gonçalves Beatriz de Souza Mello , Carvalho Flávio Leonel de , Fiorini Paula de Camargo
Published: March 2022

The objective of this article is to analyze the pre-existing studies that investigate the link between the circular economy and financial aspects in order to understand the evolution of the circular economy literature and its relationship with finance. In addition, it proposes an investigation of empirical evidence of economic-financial gains resulting from the adoption of circular production practices. The methodology used to achieve this goal was a systematic review of the literature and bibliometric analysis. Thus, it was possible to conclude that the barriers faced by companies adopting the circular economy in relation to financial performance are defined by (i) the size of the business and the initial investment cost, (ii) difficulties for micro and small companies, (iii) to a more complex structuring of the business, and (iv) greater exposure to risk, as the circular economy is a new concept and is and not as representative as a linear standard system. The results show that few studies investigate corporate gains from circular production, which is, therefore, an important topic for future research and the major contribution of this paper.

Authors: Lobo Diele , Rodriguez Ana Carolina , Casa Nova Silvia Pereira de Castro , Ardichvili Alexandre A.
Published: March 2022

There is a growing interest in how entrepreneurship animates deliberate sustainability transformations across societal levels. Few studies, however, have provided an empirically grounded account of practices employed by sustainability-driven entrepreneurial organizations for sustainability transformations. We address this gap by applying the critical Human Resource Development (CHRD) framework to identify practices for developing organizational and community capacity conducive to sustainability transformations in two cases of sustainability-driven entrepreneurship in the UNESCO World Heritage Site Serra da Capivara National Park, Brazil. We used case study methodology to identify five practices by conducting a reflexive thematic analysis with qualitative data from key informant interviews, documents, and secondary sources. Our results show that each practice was strongly oriented by relational values of care and social–ecological systems thinking. Both humans and nonhumans were taken as stakeholders who participate in and benefit from practices. Caring for the local place, place-based learning, and regenerative organizing appeared to be relevant for learning and development interventions that imparted significant changes in the local social–ecological context. We updated the CHRD framework to incorporate a nonhuman dimension and highlight caring, place-based learning, and regenerative organizing as essential areas of engagement in which HRD practices in support of place-based sustainability transformations occur.
Study on the Dust Content in Dead-End Drifts in the Potash Mines for Various Ventilation Modes
Authors: Isaevich Aleksey , Semin Mikhail , Levin Lev , Ivantsov Andrey , Lyubimova Tatyana
Published: March 2022

This article deals with the reduction of dust content in the working areas of potash mines in the conditions of operating combines. This problem is topical, since the high dust concentrations in the atmosphere of dead-end drifts lead to the development of occupational diseases among miners, and traditional methods of dust control are often unsuitable for potash salts conditions. We describe the results of experimental studies carried out for the potash mine of the Verkhnekamskoye potassium-magnesium salt deposit. Next, a mathematical model of the dust–air mixture dynamics is formulated and parametrized. The Euler–Euler approach and the model of a homogeneous multicomponent medium are used. The results of a simulation for two ventilation systems (forced and exhaust) are presented. Several options for air flow rates are considered. A conclusion is reached about the most effective parameters of ventilation systems, which allows for minimizing the concentration of dust in the zone of the combine driver.

Published: March 2022

The purpose of this study is to segment Turkish wine customers based on generational cohorts. It also explores the characteristics of the customers in each group based on wine attributes, information sources, wine consumption, purchase behaviour and socio-economic characteristics. The study’s data were collected from the listed mail addresses in some universities, institutes and company websites through a structured online questionnaire. The sample includes 708 respondents. After splitting consumers into three different generational cohorts based on the birth year (Baby Boomers, Generation X and Generation Y), the study clearly profiles the groups by employing principal component analysis, ANOVA and chi-square analyses. After splitting consumers into three groups based on generational cohorts, the study clearly identifies the differences between groups regarding wine attributes, information sources, purchasing and consumption and socio-demographic characteristics. Although there are many studies examining wine consumers in the literature from diverse countries, this is the first study investigating wine consumers based on generational cohorts in Turkey.

Authors: Che Yanjun , Cao Yun , Wu Rong , Liu Jian , Chen Lihua , Wu Jiakang
Published: March 2022

World Heritage is of high historical, artistic, and scientific value and represents wealth created by human beings or nature that cannot be replaced. In this paper, the tempo–spatial characteristics of World Heritage and its traffic accessibility were assessed in China using statistical and spatial analysis methods. The results showed that development of Chinese World Heritage experienced exploratory, evolution, accelerated development, and stable development phases. To date, there are 55 World Heritage Projects in China, including 37 Cultural Heritage, 14 Natural Heritage, and 4 mixed double heritage projects. Based on the spatial analysis, global spatial correlation of these heritage sites was not significant while the local spatial correlation was significant. The majority of the heritage sites were distributed in the east–central regions of China, and the hotspots were also concentrated in these regions. In addition, an assessment of inter-regional accessibility indicated that 63.18% of heritage sites could be reached within one hour from a city center and the average time taken to reach a heritage site was at 1.03 h in the local city. Time cost was low and accessibility was good. Additionally, an analysis of the overall accessibility showed that the average time cost of the World Heritage Sites was 25.51 h. Overall accessibility in the central plain region of China was very high, with a time cost of <15 h. The overall accessibility in the western mountains and northeastern regions was very limited. In general, the development of China’s World Heritage still has great potential and strong traffic accessibility, which can effectively promote the development of heritage tourism. Meanwhile, heritage tourism can also effectively promote the development of local economies under the principle of protection priority.
Agrivoltaics in Ontario Canada: Promise and Policy
Authors: Pearce Joshua M.
Published: March 2022

Well-intentioned regulations to protect Canada’s most productive farmland restrict large-scale solar photovoltaic (PV) development. The recent innovation of agrivoltaics, which is the co-development of land for both PV and agriculture, makes these regulations obsolete. Burgeoning agrivoltaics research has shown agricultural benefits, including increased yield for a wide range of crops, plant protection from excess solar energy and hail, and improved water conservation, while maintaining agricultural employment and local food supplies. In addition, the renewable electricity generation decreases greenhouse gas emissions while increasing farm revenue. As Canada, and Ontario in particular, is at a strategic disadvantage in agriculture without agrivoltaics, this study investigates the policy changes necessary to capitalize on the benefits of using agrivoltaics in Ontario. Land-use policies in Ontario are reviewed. Then, three case studies (peppers, sweet corn, and winter wheat) are analysed for agrivoltaic potential in Ontario. These results are analysed in conjunction with potential policies that would continue to protect the green-belt of the Golden Horseshoe, while enabling agrivoltaics in Ontario. Four agrivoltaic policy areas are discussed: increased research and development, enhanced education/public awareness, mechanisms to support Canada’s farmers converting to agrivoltaics, and using agrivoltaics as a potential source of trade surplus with the U.S.
The Competitions, Negotiations, and Collaborations of Regional Integration: A Perspective on Sustainable Management of Water Resources in Pingtung Plain, Taiwan
Authors: Tsai Shuchen , Lee Suhsin , Zou Zhe , Chu Tajen
Published: March 2022

A consultative and cooperative perspective on water management is vital in regional sustainability. However, previous approaches often failed to consider the complex trade-offs involved in water resource allocation. This study explores theoretical perspectives on regional integration as a policy goal through the process of water allocation. The main purpose is to explain new areas created by allocation and regional integration with local-scale cases. The connections between post-structuralism, fragmentation, and heterogeneity are explored with five case studies of groundwater zoning: a Xinyuan buried pipe compensation, a Ligang well closure and power shutdown, a Dachaozhou artificial lake, a Wandan hold back well, and a Meinong anti-deep-water wells. Along with the case studies, secondary literature, interviews, and a field investigation were used. The time span of water conflicts was from 1973 to 2019, and the spatial scope is the groundwater distribution area. The study found that regional integration and dynamic balance are each other’s subject and object, which was empirically verified through the water conflicts in agriculture and the semiconductor industry. Regional integration comes through scaled and flexible methods of operation, and is produced through special market agents and post-structural spaces. In the process, the imbalance caused by conflict must also be adjusted and evolved through cooperation, competition, and negotiation to maintain the dynamic balance. This involves internal treatment of the local government, external integration of the central government, and technological evolution within the organization. Accordingly, several suggestions are proposed that may be helpful for sustainable water resource governance. In summary, this study makes up for the shortcomings of water management patterns constructed by simple spatial overlaying of regional integration. Our findings could effectively enhance negotiations and collaboration in water management for regional sustainability.

Given the importance of developing and offering accessible education for all, indispensable aspects of education for sustainable development (ESD) are needed. This study addresses that need by proposing a quality self-assessment for virtual education from an accessibility perspective. This proposal is based on previous literature about quality assurance in e-learning that considered accessibility and its application in the field of higher education. The bibliographic review was conducted by following Multivocal Literature Review (MLR) guidelines. The initial search returned 999 items from 5 academic databases and 32,200 professional sources from Google. After reviewing the sources, 37 of them were included. Then, the accessibility criteria were identified and integrated into an evaluation model. Such a model is divided into four dimensions: (1) organization, (2) student body, (3) teaching, and (4) infrastructure. The model also includes a set of standards (16), requirements (48), and evidence (63) that apply to each dimension. Moreover, self-assessment guidelines for accessible virtual education were proposed. They included a conceptual and theoretical framework, a self-assessment model, and a methodology for applying the model. The methodology included five phases: planning, model tuning or refinement of the model, evaluation, results, and continuous improvement. As future work, the implementation and validation of the guidelines will be carried out.
Territorializing and Monitoring of Sustainable Development Goals in Italy: An Overview
Authors: Richiedei Anna , Pezzagno Michele
Published: March 2022

The 2030 Agenda defined 17 Sustainable Development Goals (SDGs) divided into 169 targets, applicable everywhere and based on the “No one left behind” principle. Goals and indicators to measure the achievement of the 2030 Agenda have to be localized. The paper presents the Italian current evolution of the territorialization of the SDGs, starting from the global level up to the local one, and wonders if the implementation of the 2030 Agenda takes concrete form with the quantitative monitoring of the SDGs at the local level (municipalities and not only capitals). A comparison among indicators proposed at different levels is set by using an ad hoc comparative reading grid. The analysis highlights that, in Italy, the principle barriers in the territorialization of the SDGs are the lack of data open sources, the proposal of new not adequately validated metrics by institutional/non-institutional subjects and the progressive loss of relationship with Global indicator framework and targets of the 2030 Agenda. The strategies needed to reach sustainable development are obviously site-specific, but we need to maintain common metrics in measuring performances in relation to the 2030 Agenda. In the Global indicator framework for the Sustainable Development Goals and targets of the 2030 Agenda for Sustainable Development, it is possible to find indicators suitable to measure performances at the local level—albeit in a smaller numbers—but in Italy, there is no awareness about this. Italy is completely losing both the opportunity to compare the results of the effort performed by the Municipalities in a rigorous way and the possibility to use strong metrics to support decision-makers’ policies for the future.

The aim of this paper is to develop neural models enabling the determination of biomechanical parameters for giant miscanthus stems. The static three-point bending test is used to determine the bending strength parameters of the miscanthus stem. In this study, we assume the modulus of elasticity bending and maximum stress in bending as the dependent variables. As independent variables (inputs of the neural network) we assume water content, internode number, maximum bending force value and dimensions characterizing the cross-section of miscanthus stem: maximum and minimum stem diameter and stem wall thickness. The four developed neural models, enabling the determination of the value of the modulus of elasticity in bending and the maximum stress in bending, demonstrate sufficient and even very high accuracy. The neural networks have an average relative error of 2.18%, 2.21%, 3.24% and 0.18% for all data subsets, respectively. The results of the sensitivity analysis confirmed that all input variables are important for the accuracy of the developed neural models—correct semantic models.
Sustainable Tourism Destination Image Projection: The Inter-Influences between DMOs and Tourists
Authors: Zhu Dan , Wang Jiayi , Wang Meifang
Published: March 2022

With the development of the Web 2.0 era, tourists can freely publish their destination experiences through online travel notes. This enables tourists to become important agents to project tourism destination image (TDI), impacting destination-sustainable development. Previous studies have compared the difference in the images projected by destination management organizations (DMO) and tourists through their published content. However, fewer studies have been done to explore the inter-influences between them on the diachronic process of TDI construction. From the perspective of “circle of representation” this question is researched through a case study of Chiang Mai, Thailand, regarding the market of mainland Chinese tourists. Through interviews and the collection of microblogs from the Thailand National Tourism Bureau and tourists’ travel notes from 2009 to 2021, we found that Chiang Mai has experienced four stages of TDI construction, during which the “Xiao Qingxin” image is evolutionally constructed and formed into the representation circle. The inter-influences between DMO and tourists, as well as the influencing factors in this process, are summarized. Our study supplements a dynamic diachronic analysis of TDI from the constructivism perspective. Relevant management and marketing applications for TDI and destination sustainability in the post-pandemic and Web 2.0 era are also provided.
Intelligent Optimized Wind Turbine Cost Analysis for Different Wind Sites in Jordan

Published: March 2022

Choosing the right wind site and estimating the extracted energy of the wind turbines are essential to successfully establishing a wind farm in a specific wind site. In this paper, a method for estimating the extracted energy of the wind farms using several mathematical models is proposed. The estimating method, which was based on five wind turbines, Q1, Q2, Q3, Q4, and Q5 and three wind distribution models, gamma, Weibull, and Rayleigh, was used to suggest suitable specifications of a wind turbine for a specific wind site and maximize the extracted energy of the proposed wind farm. An optimization problem, developed for this purpose, was solved using the whale optimization algorithm (WOA). The suggested method was tested using several potential wind sites in Jordan. The proposed wind farms at these sites achieved the maximum extracted energy, maximum capacity factor (CF), and minimum levelized cost of energy (LCoE) based on the solution of the developed optimization problem. The developed model with Q3 and the Rayleigh distribution function was validated with real measurement data from several wind farms in Jordan. Error analysis showed that the difference between the measured and estimated energy was less than 20%. The study validated the provided model, which can now be utilized routinely for the assessment of wind energy potential at a specific wind site.
