Evolution of heritage and development in Liverpool's waterfront over 40 years

The recent delisting of Liverpool’s World Heritage Site has highlighted the adverse impacts of ongoing urban developments on the city’s heritage. This study aims to address the critical question of how Liverpool can safeguard its heritage following the loss of its World Heritage status. As this status withdrawal implies a lack of international policy consideration, it raises important questions: What additional measures should be implemented? How could we reassess Liverpool's heritage in this new context? To tackle these issues, we investigate the changing relationship between safeguarding heritage and urban development on Liverpool Waterfront’s Historic Urban Landscape over the past 40 years. This study analyses the impact of developments on Liverpool’s heritage values, specifically focusing on Integrity, Authenticity, and Outstanding Universal Value. By employing a novel, top-down heritage impact assessment methodology, we evaluate the influence of urban and architectural developments on these values. This methodology is distinguished by its comprehensive comparative analysis of diverse elements drawn from heritage policy documents, spanning both tangible and intangible domains. In addition, we conducted interviews with experts familiar with Liverpool's heritage context to deepen our understanding of developmental impacts. The analysis framework comprises three case study areas and their associated developments: the adaptive reuse of the Albert Dock Complex (1981–1988), the Pier Head Developments (2007–2013), and the Stanley Dock Conservation Area (2021 onwards). The findings indicate that adaptive reuse schemes have been reasonably successful in preserving heritage values, whereas certain urban interventions have had detrimental effects. This study underscores the need for stricter regulations and broader stakeholder involvement to protect Liverpool's heritage. Further research is recommended, incorporating more development case studies and examining successful urban interventions in other heritage cities, to strengthen Liverpool’s heritage safeguarding strategies amidst evolving urban development pressures.

ESPR chronicles: unveiling environmental and pollution science trends across time

This study explores current research trends in environmental studies, emphasizing the importance of addressing climate change through effective strategies and highlighting the crucial role of circular economy principles and resource management in achieving sustainability goals. It aims to investigate emerging patterns and analyze the altmetric impact of published research in the field of environment and pollution. Environmental Science and Pollution Research (ESPR), a research journal published by Springer since January 1994, serves as a cornerstone for scholarly discourse in this field. The first volume of ESPR was released in January 1994, and since then, all of the information has been indexed by significant databases like OCLC WorldCat Discovery Service, SCOPUS, and DIMENSIONS, amongst others. ESPR is one of the leading journals with a five-year impact factor of 5.4 and 1.01 SJR Q1 quartile as of 2023, with an h-index of 179. The journal has published influential articles that garnered high altmetric scores, indicating online attention and engagement, although there is a notable disparity between altmetric scores and total citations. Most of the highly cited articles cover various topics, including eutrophication, electrochemical advanced oxidation processes, insecticides, and phytoremediation. Most publications fall under environmental sciences, followed by pollution and contamination. Chinese institutions have substantially contributed to the journal, indicating a strong emphasis on environmental and pollution research in China. Our findings reveal significant growth in publication output and citation rates, alongside a notable disparity between traditional citation metrics and altmetrics, underscoring the need for comprehensive impact assessment methodologies.

A Measure That Really Works? Impact Evaluation of the Contribution for Self-Employment as a Tool of Active Labour Market Policy in Slovakia

Unemployment presents a significant challenge requiring attention not only in developing countries but also in economically developed ones. Active labour market policies offer a potential solution to address this issue. This study focuses on assessing the impact of the intervention called Contribution for Self-employment provided under the Act on Employment Services No. 5/2004 Coll in the Slovak Republic. This financial support is extended voluntarily to unemployed individuals seeking jobs and aims to partially defray the expenses associated with launching business ventures. The primary objective of this research is to quantify the effectiveness of the Contribution for Self-employment in enhancing the employment of its recipients, thereby gauging its efficacy in reducing unemployment. The evaluation employs a counterfactual impact assessment methodology, utilising propensity score matching for analysis, with propensity score estimated by the logistic regression. Data from the registry of jobseekers maintained by the Central Labour Office of Social Affairs and Family in Slovakia are utilised in this analysis. This study’s findings indicate a favourable impact of the contribution on the employment of its participants compared to the comparable non-participants. Consequently, this intervention emerges as a viable mechanism for supporting entrepreneurship and mitigating unemployment in Slovakia.

Optimizing offshore wind export cable routing using GIS-based environmental heat maps

Abstract. In the United States, there are plans to produce up to 30 GW of offshore wind power by the year 2030, resulting in numerous seabed lease areas which are currently going through the leasing or construction and operations phase. A key challenge associated with offshore wind is optimal routing and installation of the subsea power cables, which transmit power from the main offshore wind energy production area to a land-based station, where it connects to the electrical grid. By traversing a vast extent of the seafloor, the installation and operational phases of subsea power cables have the potential to result in a range of environmental impacts, which may negatively affect sensitive biological, physical, human and/or cultural resource receptors. Presented here is a case study from southeastern North Carolina to identify optimal seabed cable routes and coastal landfalls for a recently leased offshore wind farm by using a combination of publicly available data, coupled with standard environmental impact assessment methodologies and geographic information system (GIS)-based heat maps. The study identified a range of high-risk areas, in addition to a number of potential low-risk routes and landfall areas which minimize seabed user conflicts and impacts on environmentally sensitive locations. Although additional high-resolution and site-specific environmental, geological and biological surveys are required to develop a robust cable installation plan, the preliminary steps from this research optimize early-phase marine spatial planning for offshore wind projects and other similar subsea industries.

Categorization of pickleball paddles as a highly impulsive sound source

As the sport of pickleball has grown in popularity and tennis courts close to homes are being converted to this use, noise regulation for pickleball courts has become a topic of discussion among city councils, planners, home owners associations, residents, and, increasingly, attorneys seeking injunctions against poorly sited or mitigated courts. Accurate noise impact assessment of the short duration impulsive sound produced by the impact of the ball on the paddles requires the use of the highly impulsive adjustment in ANSI S12.9 Part 4. Examination of the definitions of impulsive sound in this standard and in ISO 1996 Part 1 identifies characteristics of rapid onset, significant energy in the most sensitive part of the auditory spectrum, and duration as primary differentiators for categorization. The noise impact assessment methodology in ANSI S12.9 Part 4 for highly impulsive sound has proven an effective means of determining the amount of mitigation needed for pickleball facilities, being more repeatable and precise than other commonly used assessment methods while avoiding underestimation of annoyance.

Synergizing Environmental Sustainability: Unveiling the Nexus between Life Cycle Analysis and Circular Economy in the Water Sector

Over-extraction and pollution surge have created a serious management challenge for the world's water resources. Rising demand, inadequate water resource management infrastructure and unequal distribution intensify the scarcity crisis. Sustainable solutions are necessary to ensure availability, environmental conservation and resilience in the face of escalating water challenges worldwide. In today's world, the primary goal is to mitigate impact on resources. Thus, life cycle analysis (LCA), a widely embraced methodology for impact assessment can be applied for sustainable management of resources. Circular economy (CE) is the new sustainable approach by which we can reduce the waste generation by reusing and recycling the products to form a loop. Utilising LCA, environmental consequences of human activities and developing solutions for reducing waste, can put CE into practice effectively. Transforming waste into a valuable resource, whether through natural or scientific means, plays a pivotal role in advancing the principles of circular economy. The detailed application of LCA and the efficient incorporation of CE principles contribute significantly to environmental sustainability. This study articulates the interplay between CE and LCA, outlining key steps in water management. It provides a comprehensive overview of literature on life cycle analysis and circular economy, specifically focusing on their major applications in the water and wastewater treatment domain. To successfully apply circular economy, future research should concentrate on improving the processes for incorporating circular economy ideas into life cycle assessments (LCAs) and encouraging cooperation between academicians, decision-makers and stake holders.

The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) - Description and Evaluation of the Rural Employment Policy in India

This paper provides a comprehensive analysis of the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) in India, tracing its origins from the National Food for Work Programme. The study explores the policy framework, objectives, and implementation of MGNREGA, emphasizing its role in addressing work and food shortages in Indian villages. The paper employs policy analysis and impact assessment methodologies, considering factors such as rural poverty, wealth distribution, and the need for inclusive economic growth. The evaluation covers key features of the policy, including the establishment of a National Employment Guarantee Fund, weekly wage payments, gender equality, and prohibition of contractors and labour-displacing machines. The impact assessment indicates positive outcomes in areas such as income, labour rates, food security, savings, debt clearance, confidence building, and reduced distress migration. The case study of Andhra Pradesh highlights the program's effectiveness, with an average employment of 53 days per household and an additional income of Rs.5100 during the 2010-11 period. The paper underscores MGNREGA's significance in achieving participatory and equitable growth, complementing market-oriented and infrastructure-related policies.

Is normalization in Life Cycle Assessment sustainable? Alternative approach based on natural constraints

Life cycle assessment, a widely used methodology of environmental impact assessment, employs the step called normalization to allow comparison and contextualization of the multiple environmental impacts driven by human activities. However, the currently used normalization references based on total human impacts do not reflect any sustainability limits. This leads to a paradox where the more humanity causes an impact, the less important it appears in the results. We propose that normalization references be based on natural constraints, values that delimit the level of impact which can be expected to cause no significant harm. Such approach can be applied to most characterization methodologies, as we demonstrate on the case of Environmental Footprint methodology with 16 impact categories. In this work we quantify such normalization references, we compare them to the currently used values and we statistically test the difference on the case of 60 processes from common LCA databases. The results show that the proposed normalization method significantly changes the relative ranking of most of the impact categories. According to our findings, the proposed method may alter the ranking of assessed scenarios and change the conclusions and recommendations of LCA studies. This shift in the rationale for normalization can provide a different perspective on results interpretation and thus offer more robust policy guidance.

Analysis of the Impact of Agricultural Production Type and Traffic on Nitrogen Oxide Emissions

The protection of air from pollution is one of the basic principles of sustainable development, and this article analyzes the joint impact of various types of agricultural production and traffic on nitrogen oxide (NOx) emissions. The goal of this research is the development of a new methodology for assessing the combined impact of different types of agricultural production, traffic load, and traffic flow structure on the emission of nitrogen oxides. For the analysis of the joint impact of traffic and agricultural production, a new impact assessment methodology was developed, which is based on two selected impact prediction models. The following two models were used to predict the impact: the BioGrace model and the microsimulation model VISSIM. The developed methodology was applied to a case study in real field conditions. The results showed that the difference in the emission of NOx gases, depending on the type of agricultural production, indicates a reduction in NOx emissions in the walnut–winter-wheat system by 30%, compared to the production of winter wheat in an open field. The statistical analysis showed that there is no statistically significant difference between NOx emissions for different vehicle arrival scenarios for the same traffic load. The results of the joint impact show that the lowest NOx emission was found in walnut orchards and counted traffic. In this example, the difference between the one-hour emission load of three different agricultural types of production and traffic is not large; however, in the cumulative load, it can lead to significant differences. Emphasizing the importance of adopting new agricultural practices and the impact of traffic and the share of freight and heavy goods vehicles in agricultural production, we position them as a proactive and sustainable response to the critical ecological and agricultural challenges highlighted in European and Croatian policy.

Life Cycle Assessment of a Jet Printing and Dispensing Machine

Life Cycle Assessment (LCA) is a well-known methodology used to calculate the environmental impacts of a product across its life cycle. The industrial machines used to manufacture consumer products are generally heavy, bulky, and have a complex product structure which makes their environmental assessment using LCA difficult as well as time and resource-intensive. Few studies have conducted LCA of complex industrial machines. The paper presents an LCA of a jet printing and dispensing machine (MY700), an industrial machine used in the production of printed circuit boards (PCBs) carried out using ReCiPe 2016 (Hierarchist) impact assessment methodology. In this study, the use phase of the machine accounted for 91% of the total environmental impacts. The compressed air and electricity consumed in the use phase of the machine were the major environmental hotspots. Additionally, some measures to minimize energy and compressed air use are also discussed. The methodology proposed in this article can be adopted by practitioners to conduct LCA of other industrial machines. The results of this study can help the machine manufacturers to undertake relevant eco-design activities as well as a comparison of different versions/machines in the product family for their environmental impact.

Life Cycle Assessment and Circular Building Design in South Asian Countries: A Review of the Current State of the Art and Research Potentials

A literature survey was proposed, aiming at summarizing the state of the art and, consequently, the research potential, in the increasingly popular field of circular economy, specifically applied to the construction industry in South Asian countries (Pakistan, India, and Bangladesh). In particular, the role of a life cycle assessment (LCA) to support the circular building design concept in construction projects was investigated. This review organized 71 published papers that examined environmental building assessments, certifications for sustainable buildings, the awareness of sustainable buildings, and recent advancements in this field between 2005 and 2022. The review pointed out that half of the LCA studies used the cradle-to-grave LCA methodology for environmental impact assessment, while the other half used the cradle-to-cradle LCA methodology. Regardless of the recent research, the literature still lacks the cradle-to-cradle implementation of the LCA methodology in selected countries which is essential for implementing truly circular building strategies. Moreover, the literature showed a lack of interest and awareness among all stakeholders in the construction of environmentally friendly buildings. The main barrier to carry out LCA for building performance is the unavailability of a regional database, which was pointed out in the literature, as well as the criteria for certification that are not available or do not comply with the standards of the specific contexts of Pakistan, India, and Bangladesh.

Assessment of health impacts and costs attributable to air pollution in urban areas using two different approaches. A case study in the Western Balkans

In this study, two different air quality impact assessment methodologies were adopted and combined with a sensitivity analysis to estimate the unit costs. Air pollution health impact (mortality) assessment was carried out using one methodology based on log-linear concentration response functions (CRF) and another relying on the integrated exposure response curve (IER) from the Global Burden of Disease. Morbidity impacts were estimated with the CRF approach only. To assess the inequalities between low and high income countries, an area of low-medium income countries with a critical air pollution situation, was selected. The health impact and related external costs attributable to air pollution in 2019 were assessed in 30 urban areas of the Western Balkans region, one of Europe’s air pollution hot spots. The evaluation was based on PM2.5, O3 and NO2 concentrations in background sites from official monitoring networks. In 2019, the cost of mortality attributable to PM2.5 in 26 urban areas was 7.8 and 9.0 billion Euro according to IER and CRF methodologies, respectively. The cost of O3 associated with all-cause mortality estimated with the CRF methodology in 17 urban areas was 1.0 billion Euro while the one attributable to NO2 pollution in 28 urban areas was 1.5 billion Euro. The study results suggest that the economic burden of air pollution in the Western Balkans is higher in terms of GDP than the one observed in EU27 in the same time window. The study concludes that CRF and IER methodologies are coherent, because the discrepancy in the results are explained by the differences in the assessed health outcomes. The two approaches are complementary because the combination of them makes it possible to obtain a wider range of outcomes. In addition, despite the different causes of death considered, the comparison between them is useful for cross-validation.

Health risk assessment of workers' exposure to BTEX and PM during refueling in an urban fuel station.

The proximity of fuel stations to the roads and the activities inside the station can contribute to PM and VOCs and impose health risks on station workers. The study presents the exposure and health risk assessment of the fuel station personnel to total volatile organic compounds (TVOCs) and particulate matter (PM) during refueling operations. TVOCs and PM monitoring were carried out at a fuel station in Chennai, India, for 1 week in March 2021, covering both weekdays and weekends. The health risks were assessed using EPA's health impact assessment methodology. Exposure to TVOCs (3177.39 ± 5450.32 μg/m3) exceeded the EPA standard of 5 μg/m3, by more than 500 times, peaking during refueling operations. The average concentrations of PM10, PM2.5, and PM1 were 76.55 ± 23.08 μg/m3, 41.81 ± 9 μg/m3, and 30.38 ± 7.56 μg/m3, respectively. The concentrations were observed to be high during morning and evening hours due to the increased traffic on the adjacent road and inside the fuel station. The synergistic health risks linked with long-term exposure to high concentrations of BTEX and PM were also estimated. At the fuel station, a significant contribution to the SOA formation potential was shown by toluene, followed by m-xylene, p-xylene, o-xylene, ethylbenzene, and benzene. Furthermore, the deposition of airborne particles in the workers' respiratory tract was calculated using the Multiple Path Particle Dosimetry model while considering the daily average exposure duration of 12 h. The results showed that 59% of PM10 particles were deposited in the head region, whereas 11% and 10% of PM2.5 and PM1 particles were deposited in the pulmonary region. Hence, the health risk assessment indicated no non-cancer risk of exposure to PM (hazard quotient = 0.13) to station personnel exposed regularly for 1 year. However, prolonged exposure to VOCs for more than 1 year can result in both carcinogenic and non-carcinogenic risk (hazard quotient = 0.045 and cancer risk > 10-6) in workers.

Cybersecurity Challenges for Manufacturing Systems 4.0: Assessment of the Business Impact Level

An ever-growing number of companies are moving toward the Industry 4.0 paradigm, adopting a range of advanced technologies (e.g., smart sensors, big data analytics, and cloud computing) and networking their manufacturing systems. This improves the efficiency and effectiveness of operations but also introduces new cybersecurity challenges. In this article, the impact assessment methodology is applied in the context of manufacturing systems 4.0 (also known as smart manufacturing systems, cyber manufacturing systems, or digital manufacturing systems), thus identifying the critical assets to be protected against cyber-attacks and assessing the business impacts in the case of subtractive and additive technologies. The research design of the single case study with multiple units of analysis is applied. In particular, a large company, a leader in the manufacturing of aeronautical components, is considered a representative case study, and its two main types of manufacturing cells that is, those based on networked computer numerical control machines and 3-D printers, are taken as applicative cases for the methodology. The application of the impact assessment methodology in the manufacturing context 4.0 of aeronautical components represents a useful guide for researchers in the field of cybersecurity and for companies intending to implement it in their smart manufacturing environments. In particular, based on this study, companies can define the critical manufacturing data to protect against cyber-attacks, isolate the business impacts in case of cybersecurity breaches, correlate the identified business impacts with the specific data category, and assess the level of business impacts.

Life-cycle assessment of microwave-assisted pyrolysis of pine sawdust as an emerging technology for biodiesel production

Although biofuels are often presented as a renewable and eco-friendly substitute to fossil fuels, it is crucial to have a comprehensive understanding of the complete environmental consequences of biofuel production to make well-informed choices about their usage. This study evaluated the environmental impacts of producing biodiesel from microwave-assisted pyrolysis (MAP) of pine sawdust using life-cycle assessment. A cradle-to-gate system boundary approach encompassing pine cultivation, biomass pre-processing, pyrolysis, and biofuel synthesis via transesterification was used. The ecoinvent v3.7 in openLCA v2.0 software was used to assess the environmental sustainability of the system. The ReCiPe 2016 (H) midpoint impact assessment methodology was used to analyze 18 environmental impact categories. The results showed that producing 1 kg of biofuel from MAP of pine sawdust had environmentally favorable impacts for most categories except global warming potential (1.18 kg CO2 eq.), photochemical oxidant formation (0.71 kg NMVOC eq.), and human toxicity (2.46 kg 1,4-DCB eq.). Biomass production contributed significantly to global warming, freshwater ecotoxicity, human toxicity, and marine ecotoxicity. Pyrolysis contributed 33 % of global warming potential due to non-condensable gas emissions. Biofuel synthesis impacted human toxicity, photochemical oxidant formation, and terrestrial ecotoxicity, mainly due to methanol use. Implementing sustainable practices such as using organic fertilizers, optimization of transportation routes, implementing gas cleaning technologies and effective waste management practices can enhance the environmental performance of this biofuel production system.
