ABSTRACT

The unprecedented lockdown of human activities during the COVID-19 pandemic has significantly influenced social life in China. However, understanding the impact of this unique event on the emissions of different species is still insufficient, prohibiting the proper assessment of the environmental impacts of COVID-19 restrictions. Here we developed a multi-air-pollutant inversion system to simultaneously estimate the emissions of NOx, SO2, CO, PM2.5 and PM10 in China during COVID-19 restrictions with high temporal (daily) and horizontal (15 km) resolutions. Subsequently, contributions of emission changes versus meteorological variations during the COVID-19 lockdown were separated and quantified. The results demonstrated that the inversion system effectively reproduced the actual emission variations in multi-air pollutants in China during different periods of COVID-19 lockdown, which indicate that the lockdown is largely a nationwide road traffic control measure with NOx emissions decreasing substantially by ∼40 %. However, emissions of other air pollutants were found to only decrease by∼10% because power generation and heavy industrial processes were not halted during lockdown, and residential activities may actually have increased due to the stay-at-home orders. Consequently, although obvious reductions of PM2.5 concentrations occurred over the North China Plain (NCP) during the lockdown period, the emission change only accounted for 8.6 % of PM2.5 reductions and even led to substantial increases in O3. The meteorological variation instead dominated the changes in PM2.5 concentrations over the NCP, which contributed 90 % of the PM2.5 reductions over most parts of the NCP region. Meanwhile, our results suggest that the local stagnant meteorological conditions, together with inefficient reductions of PM2.5 emissions, were the main drivers of the unexpected PM2.5 pollution in Beijing during the lockdown period. These results highlighted that traffic control as a separate pollution control measure has limited effects on the coordinated control of O3 and PM2.5 concentrations under current complex air pollution conditions in China. More comprehensive and balanced regulations for multiple precursors from different sectors are required to address O3 and PM2.5 pollution in China.

ABSTRACT

Le débat relatif à l'impact environnemental du numérique présente un degré de complexité qui ne peut être approché à la seule observation de la progression de son poids dans les émissions de CO2 ou les consommations électriques. Des travaux récents permettent de mieux appréhender ses effets induits, en établissant notamment dans quel sens les usages du numérique influencent la trajectoire des émissions des États ou agissent sur des cobénéfices de l'action climatique (comme la qualité de l'air). En outre, ces analyses devront être resituées dans le prolongement de la crise sanitaire (et du développement des activités socio-économiques « à distance »), ainsi que dans celui de la crise énergétique (qui implique une optimisation de systèmes gagnant en complexité du fait d'un développement accéléré des renouvelables, des efforts d'efficacité...). Ces travaux débouchent sur un constat contrasté de l'impact environnemental du numérique (qui, toutefois, n'invalide pas l'impératif de l'effort de sobriété).Alternate :The debate on the environmental impact of digital technology is complex and cannot be approached simply by observing the increase in its weight in CO2 emissions or electricity consumption. Recent work has made it possible to improve the understanding of induced effects, in particular by establishing the extent to which the uses of digital technology influence the emissions trajectory of States or act on the co-benefits of climate action (such as air quality). Furthermore, these analyses must be placed in the context of the health crisis (and the development of 'remote' socio-economic activities), as well as the energy crisis (which involves optimising systems that are becoming increasingly complex due to the accelerated development of renewables, efficiency efforts, etc.). This work leads to a contrasting assessment of the environmental impact of digital technology (which, however, does not invalidate the need for sobriety efforts).

ABSTRACT

In the post-COVID-19 era of green economic recovery, this paper analyses the elderly care environment of cities in the Yangtze River Delta (YRD) region and investigates the future development direction of the elderly care industry based on comparative advantages and resource endowment. Firstly, an evaluation index system of the elderly care environment is constructed, then the entropy weight method is used to calculate the weight, and finally the comprehensive evaluation index of the elderly care environment in each city is obtained by weighted calculation. The development directions of the elderly care industry for each city in the YRD region are proposed based on the results. The study shows that the suitable development direction of the elderly care industry differs among cities. Cities suitable for residential elderly care are mainly distributed in the central and western regions, cities fit for the leisure and tourism of elderly care are mainly located in the southeast, and cities suitable for the treatment and rehabilitation of elderly care are mainly provincial capitals and cities with better economic development levels. Additionally, Wenzhou City in Zhejiang Province is eligible for the development of a comprehensive elderly care industry. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

ABSTRACT

As a global concern, medical waste (MW) links public health, environmental pollution, and resource sustainability. This study aims to assess the two issues related to medical waste in Bahrain: the increasing generation rate of MW and its management. The integrated Environmental Assessment (IEA) methodology was adopted, including the DPSIR (Drivers, Pressures, State, Impact, Responses) framework, analysis of existing policies, and the outlook. Consequently, data were collected from official health statistics in Bahrain, and related policies for the last two decades (2001 to 2021) were also collected, in addition to interviews with Bahrain medical waste (BMW) treatment company. The results show a vast increase in medical waste during COVID-19. Moreover, most of the existing policies address the impact of the BMW issues, but the policies are lacking in tackling the drivers and pressures;there is also a policy gap related to the generation rate. Accordingly, a set of policies was proposed to overcome the two medical waste issues. Moreover, to overcome issues associated with MW, the study recommended reforming regulations aiming to reduce and manage medical waste efficiently in order to focus more on drivers and pressure causing an elevation in MW issues in Bahrain. © 2023 by the authors.

ABSTRACT

Pollution is one of the leading risk factors for the deterioration of the environment, mankind's poor health, and endangerment of the plant kingdom. The exploration of water pollution levels through a new remote sensing model "Water Pollution Index” makes this study unique, which is derived from the weighted overlay technique using land surface temperature, Chlorophyll Index, NCAI, and backscattering values from Sentinel 1, Sentinel 2, and Landsat 8 data sets. This chapter is concerned with the qualitative study of water pollution of the Yamuna river stretch, Delhi. To substantiate the results, sources are taken from different published papers and ground surveys. The objective is to define the pollution level and its contributing factors, algae blooming, sewage debris, coronavirus disease 2019 (COVID-19) shutdown impact, and rain in different seasons for two consecutive years, 2019 and 2020. A noticeable difference is found in the annual result indicating less pollution in 2020 especially in premonsoon data compared to 2019. © 2023 Elsevier Inc. All rights reserved.

ABSTRACT

BACKGROUND: Occupational therapist-led environmental assessment and modification (EAM) is effective in reducing falls for populations at high risk. Two regional and rural public health services in Queensland devised an implementation strategy to embed best practice occupational therapist-led EAM. METHODS: A qualitative study was conducted to compare the determinants of implementation success across the different health services, using the COM-B model of behaviour change. Six semi-structured interviews were completed with occupational therapists involved at each site, following 12 months of implementation. Interview data were triangulated with minutes from three combined site steering committee meetings, eight local steering committee meetings, and field notes. Thematic analysis was completed to compare barriers and facilitators to best practice uptake of EAM and differences in outcomes between the two sites. RESULTS: Both sites commenced implementation with similar states of capability and motivation. After 12 months, one site considered that practice change had been embedded as noted in steering committee minutes and comments; however, the other site observed limited progress. According to the COM-B analysis, opportunity (the factors that lie outside the individual's control) had a significant influence on how both sites were able to respond to the practice change and navigate some of the unexpected challenges that emerged, including the COVID-19 pandemic. Existing team structure, multiple responsibilities of key stakeholders, differences in access to resources, and lack of connection between complementary services meant that COVID-19 disruptions were only a catalyst for unveiling other systemic issues. CONCLUSION: This study highlights the power of external factors on influencing behaviour change for best practice implementation. Learnings from the study will provide deeper understanding of completing implementation projects in regional and rural contexts and support the future implementation of EAM in occupational therapy clinical settings.

ABSTRACT

During the first waves of the Covid-19 pandemic period, urban environments were stressed;the resilience of our cities were tested, highlighting the strengths and weaknesses of the urban contexts, not always capable to promote and protect the population health status. Urban Green Spaces (UGS) have proved essential role as “tools” to improve Urban Public and Mental Health. Unfortunately, the heterogeneous distribution of UGS inside the contemporary cities, together with the disparity in quality of such spaces, led to some exclusion phenomena. The paper would describe a research experience based on four consequential phases: theoretical background update;tool definition phase (Quantitative assessment: Proximity of the UGS in Milano, and Qualitative assessment: RECITAL 2.0 Milano);application phase in the urban context of Milano city and findings analysis. About the application phase, 24 parks were evaluated: by the comparison of the “RECITAL 2.0 Milano” results with the UGS surface data, no significant pattern emerges, that means that environmental quality is not linked to the extension of the UGS. By the comparison of the overall score with the average real estate values in the analyzed area, emerges an easily readable and expected correlation: the top-performing parks are in the most exclusive areas of the city, often in or near the city center, easily reachable by public transportation alternatives. Qualitative assessments can detect criticalities in-side the urban environment, while quantitative assessments can find areas of the cities deprived of the benefits of UGS. The overlap of both findings could be an indicator of the presence of some form of exclusion phenomena, thus requiring attention both of Urban Planners and Policy Makers to ensure healthier and more equal urban environments. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

The tourism industry has become a significant economic contributor to a number of countries worldwide. Until COVID-19, tourism was the world's largest and fastest-growing business. The importance of tourist arrivals and the examination of their effects has triggered curiosity among different researchers, as tourism helps in balance of payment and boosts the overall GDP of the nation. Thus, this paper aimed to examine the long-run relationship among the number of tourist arrivals per year and economic growth (proxied by GDP). The study used annual secondary data collected from World Development Indicators between 1995 and 2019. Cointegration test (ARDL bounds test) was applied to check the long-run relationship among the variables. The result shows that a 1% increase in tourist arrivals, in the long run, is associated with a 1.15% increase in GDP at a (p<0.05) significance level, other things remaining constant. The evidence from ARDL bounds cointegration test confirms that tourist arrivals have a long-run relationship with a significant impact on GDP in Nepal. Thus, this study recommends some policy implications like the allocation of government funds for infrastructure and tourism development is critical since these investments benefit the tourism industry and overall GDP of the country © 2022 Editura Universitatii din Oradea.

ABSTRACT

The risk assessment of water environments provides important references for water environment risk management. In this paper, the water environment risk of the upper rivers of the Baiyangdian Lake is assessed, considering both cumulative and sudden environmental risk. For the cumulative environmental risk assessment of the rivers, the characteristics of pollution transmissibility and accumulation in rivers was considered firstly. Furthermore, suggestions for the control of water environment pollution in the Baiyangdian Basin are given. The results indicate that the cumulative water environment risks of the Xiaoyi River—Dingzhou County, Xiaoyi River—Anguo County, Xiaoyi River—Boye County, and Xiaoyi River—Li County are high. The amount of fertilizer applied per unit of cultivated area, water quality, rate of water quality above the standard in water function zoning, and the ratio of environmental investment to gross domestic product (GDP) are important factors influencing the cumulative water environment risk. For sudden water environment assessments, the Xiaoyi River—Boye County is high. In the future, reducing the intensity of fertilizer application, strengthening the water quality control of the rivers, as well as upgrading the industry, should be carried out to protect the water environment in the Baiyangdian Basin.

ABSTRACT

In a resource-constrained world, there is ongoing concern over the exploitation and potential future shortage of Earth’s natural resources. In this paper, we present the results of two pilot studies in which we used drone technology with spatial mapping tools and environmental and economic analysis to map illegal waste sites. Besides the technical feasibility, we aimed at understanding the benefits, costs, and tradeoffs of extracting the materials stocked therein, transforming illegal waste sites into valuable resources. The innovation of our work is reflected in the integration of existing technologies for aerial mapping and economic\environmental assessment methodologies for promoting a local circular economy. The pilot results suggest that it is feasible to identify valuable materials left on the ground in the form of unattended, illegally disposed waste. Our initial national estimates for the illegal waste cleanup based on the pilot results suggest that the treatment cost in Israel can be reduced by 58 million USD and even reach zero, with the potential to generate up to 82.8 million USD profits. Finally, we link our results to the Sustainable Development Goals framework and suggest how mapping and implementing the recycling potential can promote achieving some of the goals. Our work provides missing data that the state, local authorities, contractors, and companies that monitor and manage waste and recycled raw materials may find useful.

ABSTRACT

To compensate for the research defects of strong subjectivity in determining oil spill amount, insufficient consideration of wharf distribution, and incomplete indexes for reflecting the influence degree of oil spill accidents on water sources, and to enhance the supervision efficiency of the supervision department, this paper constructs a risk assessment system of water sources under the influence of the wharf group. The system includes a wharf group division method considering the wharf distribution situation;the calculation method of oil spill amount at wharves considering the oil tank capacity of main ship types and the production supervision risk at the wharves;the calculation method of the oil spill amount at the wharf group considering the wharf number, distribution density, production supervision risk and wharf oil spillage;the determination method for the influence degree of oil spill at the wharf group on the water sources and judgment method of supervision level at the wharf group, which takes the arrival time of oil slicks, the duration of over-standard petroleum concentration and the maximum over-standard multiple of petroleum concentration at the water intake as indexes;the method of determining the risk of oil spill accidents at the water source considering the cumulative effect of oil spill at the wharf group on the risk of the water sources;and the environmental risk assessment method of water sources considering oil spill accident risk and the anti-risk ability. Applying this system to the environmental risk assessment of the Zhengrunzhou water source in Zhenjiang City, we discovered that the flow field, wind field, oil spill location and oil spill amount were correlated with the influence degree of oil spill accidents on water sources, for which the flow field demonstrated the strongest correlation, while the wind field presented the weakest. The supervision level of the wharf group is mainly sub-key or non-key levels, but the level of the wharf group SD07 is approximate to the key supervision level during rising tide. Due to the strong anti-risk ability of the Zhengrunzhou water source, the environmental risks of the Zhengrunzhou water source under different working conditions are scarcely different and belong to the medium-risk level.

ABSTRACT

The current world situation marked by the COVID-19 pandemic, plus the various specific situations in each locality, require an adequate response to promote development. One of the most recommended is the development of tourism, and precisely that it is linked to the environmental environments of nature. For this reason, geotourism offers guarantees of biosecurity, open spaces, and better conditions in the current situation. Guayaquil, a cosmopolitan city on the Ecuadorian coast, has unique characteristics for the development of geotourism. This work aims to carry out an environmental analysis, using the cause-consequence method and tourist carrying capacity in geosites for sustainable geotourism development. The methodology includes: (i) strategic geosites selection;(ii) environmental assessment of geosites and analysis of their carrying capacity for tourism;and (iii) interpretation of results and strategy development. The results reflect that Guayaquil has very significant potential given its natural geological and biological conditions. The union of geodiversity and biodiversity give the Guayaquil metropolis a special uniqueness, auguring an excellent future for geotourism development. It is vital the develop geosites with an environmental consideration that allows projecting towards sustainable development.

ABSTRACT

Monitoring progress toward green economy has been a key policy focus globally. The purpose of our study is to assess Asian countries' green development performance and also the progress toward green economy overtime. To achieve this goal, we propose a green development index (GDI) to assess the level and ranking of green development for Asian countries, and then we measure the progress toward green economy by the method based on the compound annual growth rate (CAGR). The result shows that the northeast Asian countries together with Singapore and Israel are leaders in green development performance across Asia, but the most progress toward green economy has been achieved by some medium green development level countries, like China. Countries with the fastest movement away from green economy are some laggard countries with poor green development performance, such as Syria and Yemen. More generally, the leading countries have reached a high green development level, and the medium ones move fast toward green economy, whereas some laggards get worse. We also discuss the implications for public health in environmental protection, green consumption, and green production.

ABSTRACT

The COVID-19 crisis has again highlighted our need to be in close contact with nature. Approaches such as biophilic urbanism, which seek to re-naturalize cities through its inclusion in planning and design, have thus gained relevance. The biophilic urbanism approach is materialized through the Biophilic Cities Network (BCN) and uses indicators to measure cities' biophilic performance. To date, Chilean cities have not formally implemented the approach. However, the Strategic Environmental Assessment (SEA), a mandatory policy process, requires the inclusion of environmental issues in Chilean urban planning. The purpose of this paper is to explore the extent to which SEA might contribute towards the implementation of biophilic urbanism in planning processes. We analyze how local governments have been including biophilic elements in their SEA processes by exploring the Communal Regulatory Plan (PRC). We perform a content analysis on the indicators in 135 reports associated with each SEA process. The analysis revealed 286 of 1,006 indicators containing biophilic elements extracted from the biophilic cities indicators. We found that biophilic elements linked with the inhabitant's engagement and well-being were largely absent. Conversely, those indicators related to the creation of new green urban infrastructures were widely represented. Overall, the paper hints at the potential usefulness of the SEA to increase biophilic urbanism implementation in urban planning by applying indicators that include biophilic elements.

ABSTRACT

Renewable energy communities (RECs) are alternatives toward sustainable production and consumption pathways. In 2020, Italy implemented the EU Directive 2018/2001, defining a common framework for promoting energy from renewable sources. The “Famiglia di Maria”, a foundation dealing with social issues in San Giovanni a Teduccio, Napoli (Italy), in collaboration with “Legambiente” and “Con il Sud” Foundations, released the first Solidarity Oriented Renewable Energy Community project in Italy. Therefore, by applying social life cycle assessment (s-LCA) and life cycle assessment (LCA) methodologies, this study aims to: (i) promote the dissemination of RECs in the Italian and European contexts, (ii) suggest REC scenarios for the best social and environmental solutions, and (iii) support the policymakers for sustainable local development. Some key results show that the solidarity-oriented project has already produced mature outcomes about community cohesion. In contrast, technical skills and awareness about environmental issues still need to be further developed and shared among the stakeholders. Finally, social and environmental indicators converge on the self-consumption model as a feasible alternative for energy justice, community empowerment, and economic and market competition independence.

ABSTRACT

Scientific evidence shows that each place/environment generates specific conditions with associated impacts on the mental health and well-being of the population. A holistic, multilevel and integrated environmental approach to mental health enhances the understanding of this phenomena, supporting the local decision-making processes to improve spatial planning of neighbourhood environments. The aim of this study is to develop a strategic assessment framework, based on four municipalities in the Lisbon Region (Portugal), that explores policy and planning initiatives capable of generating favourable neighbourhood environmental conditions for mental health while also detecting risks. Using baseline results of significant statistical associations between individuals’ perceptions of their neighbourhood environment and their mental health in the Lisbon Region, a Strategic Focus on Environmental and Mental Health Assessment framework (SEmHA) was built, by applying the methodology “Strategic Thinking for Sustainability” in Strategic Environmental Assessment, developed by Partidário in 2012. Taking into account the promotion of the population’s mental health, four critical decision factors of neighbourhood environments were identified: (1) public space quality (e.g., improving sense of place), (2) physical environment quality (e.g., low levels of noise exposure), (3) professional qualification and creation of economic activities (e.g., attracting new economic activities), and (4) services and facilities (e.g., improving access to health and education services). The proposed strategic focus and assessment framework contributes to ensuring that interventions in neighbourhood environments truly achieve community mental health benefits and reduce inequalities, thus helping policy makers to assess impacts at the local level.

ABSTRACT

Within the last decade, research on torrefaction has gained increasing attention due to its ability to improve the physical properties and chemical composition of biomass residues for further energetic utilisation. While most of the research works focused on improving the energy density of the solid fraction to offer an ecological alternative to coal for energy applications, little attention was paid to the valorisation of the condensable gases as platform chemicals and its ecological relevance when compared to conventional production processes. Therefore, the present study focuses on the ecological evaluation of an innovative biorefinery concept that includes superheated steam drying and the torrefaction of biomass residues at ambient pressure, the recovery of volatiles and the valorisation/separation of several valuable platform chemicals. For a reference case and an alternative system design scenario, the ecological footprint was assessed, considering the use of different biomass residues. The results show that the newly developed process can compete with established bio-based and conventional production processes for furfural, 5-HMF and acetic acid in terms of the assessed environmental performance indicators. The requirements for further research on the synthesis of other promising platform chemicals and the necessary economic evaluation of the process were elaborated.

ABSTRACT

Assessing the dynamics of Bhasan Char is very crucial, as the Government of Bangladesh (GoB) has recently selected the island as the accommodation of the FDMN. This article critically evaluates the spatiotemporal morphological variations due to erosion, accretion, and subsurface deformation of the island through multi-temporal geospatial and geophysical data analysis, groundwater quality-quantity, and also determines the nature and rate of changes from 2003 to 2020. This is the first study in this island on which multi-temporal Landsat Satellite Imagery and seismic data have been used with geospatial techniques with Digital Shoreline Analysis System (DSAS) and petrel platform, respectively. The analysis of satellite images suggests that the island first appeared in 2003 in the Bay of Bengal, then progressively evolved to the present stable condition. Significant changes have taken place in the morphological and geographical conditions of the island since its inception. Since 2012, the island has been constantly accreted by insignificant erosion. It receives tidally influenced fluvial sediments from the Ganges-Brahmaputra-Meghna (GBM) river system and the sedimentary accretion, in this case, is higher than the erosion due to relatively weaker wave action and longshore currents. It has gained approximately 68 km2 area, mostly in the northern part and because of erosion in the south. Although the migration of the Bhasan Char was ubiquitous during 2003–2012, it has been concentrated in a small area to the east since 2018. The net shoreline movements (NSM) suggest that the length of the shoreline enlarged significantly by around 39 km in 2020 from its first appearance. Seismic and GPS data clearly indicate that the island is located on the crest of a slowly uplifting low-amplitude anticline, which may result in a stable landform around the island. Based on the analysis of historical data, it has been assessed that the current configuration of Bhasan Char would not be severely affected by 10–15-foot-high cyclone. Therefore, FDMN rehabilitation here might be safer that would be a good example for future geo-environmental assessment for any areas around the world for rehabilitation of human in remote and vulnerable island. The findings of this research will facilitate the government’s decision to rehabilitate FDMN refugees to the island and also contribute to future research in this area.

ABSTRACT

Background: Radioactive contamination and chemical pollution of the environment can affect the processes of carcinogenesis, including the formation of malignant neoplasms of the ovaries in women. We used the data of official state statistics for 2000-2020 to test the hypothesis about the effect of radioactive contamination (following the Chernobyl disaster) and chemical pollutants on the incidence of ovarian malignancies in the female population of the Bryansk region. Methods: A variety of statistical approaches were used to estimate the incidence of ovarian malignancies, including the Shapiro-Wilk test, Mann-Whitney U test, Spearman's rank correlation test and linear regression. Results: We did not establish statistically significant differences in the frequency of primary morbidity of women with malignant neoplasms of the ovaries, regardless of the environmental conditions of living. Furthermore, no significant correlations were found between the frequency of primary morbidity of ovarian malignancies, both with the level of contamination by Cesium-137 and Strontium-90, and air pollution with volatile organic compounds, carbon monoxide, sulfur dioxide and nitrogen oxides. A statistically significant increase in the long-term trend in the frequency of ovarian malignant neoplasms was revealed in the areas of chemical pollution (p = 0.02), however, in other territories, no statistically significant regularities were established. The forecast of the frequency of newly diagnosed malignant neoplasms of the ovaries on average in the Bryansk region shows an increase of 12.4% in 2020 in comparison with the real data for 2020, while the largest increase in predicted values is recorded in the territories of radioactive contamination (by 79.6%), and the least in the combined territories (by 6.9%). Conclusions: The results obtained indicate the need for further work to understand the trends in the presence/absence of independent and combined effects of pollutants and the growth of oncogynecological pathology from the perspective of assessing the distant and regional metastasis, histological and immunohistochemical profile of a specific malignant ovarian neoplasm with levels of environmental contamination.
