Detection of pan-azole resistant Aspergillus fumigatus in horticulture and a composting facility in Belgium.

Azole resistance in Aspergillus fumigatus (ARAf) is becoming a worldwide health threat due to increasing occurrence in the environment. However, environmental surveillance programs are not commonly in place and are lacking in Belgium. Since no data on the occurrence of ARAf and the presence of hotspots for the selection of azole resistance is available in Belgium, a first study on the prevalence of ARAf in the environment was conducted. A total of 232 air and compost or soil samples were taken from two composting facilities, and from horticultural and agricultural crops. The azole susceptibility pattern was determined using the EUCAST method (E. Def. 9.4), and the cyp51A gene and its promotor region were sequenced in A. fumigatus isolates with phenotypic azole resistance. Six pan-azole-resistant A. fumigatus isolates were identified, originating from compost and horticultural crops. Four isolates carried the TR34/L98H mutation, and one isolate carried the TR46/Y121F/T289A mutation. However, we did not observe any ARAf isolates from agricultural crops. In conclusion, this study reported the first TR34/L98H and TR46/Y121F/T289A mutation isolated from a composting facility and horticulture in Belgium. The implementation of standardization in environmental surveillance of A. fumigatus on a European level would be beneficial in order to identify hotspots.

Continuing benefits of the Montreal Protocol and protection of the stratospheric ozone layer for human health and the environment

The protection of Earth’s stratospheric ozone (O3) is an ongoing process under the auspices of the universally ratified Montreal Protocol and its Amendments and adjustments. A critical part of this process is the assessment of the environmental issues related to changes in O3. The United Nations Environment Programme’s Environmental Effects Assessment Panel provides annual scientific evaluations of some of the key issues arising in the recent collective knowledge base. This current update includes a comprehensive assessment of the incidence rates of skin cancer, cataract and other skin and eye diseases observed worldwide; the effects of UV radiation on tropospheric oxidants, and air and water quality; trends in breakdown products of fluorinated chemicals and recent information of their toxicity; and recent technological innovations of building materials for greater resistance to UV radiation. These issues span a wide range of topics, including both harmful and beneficial effects of exposure to UV radiation, and complex interactions with climate change. While the Montreal Protocol has succeeded in preventing large reductions in stratospheric O3, future changes may occur due to a number of natural and anthropogenic factors. Thus, frequent assessments of potential environmental impacts are essential to ensure that policies remain based on the best available scientific knowledge.Graphical abstract

A one health approach for monitoring antimicrobial resistance: developing a national freshwater pilot effort.

Antimicrobial resistance (AMR) is a world-wide public health threat that is projected to lead to 10 million annual deaths globally by 2050. The AMR public health issue has led to the development of action plans to combat AMR, including improved antimicrobial stewardship, development of new antimicrobials, and advanced monitoring. The National Antimicrobial Resistance Monitoring System (NARMS) led by the United States (U.S) Food and Drug Administration along with the U.S. Centers for Disease Control and U.S. Department of Agriculture has monitored antimicrobial resistant bacteria in retail meats, humans, and food animals since the mid 1990's. NARMS is currently exploring an integrated One Health monitoring model recognizing that human, animal, plant, and environmental systems are linked to public health. Since 2020, the U.S. Environmental Protection Agency has led an interagency NARMS environmental working group (EWG) to implement a surface water AMR monitoring program (SWAM) at watershed and national scales. The NARMS EWG divided the development of the environmental monitoring effort into five areas: (i) defining objectives and questions, (ii) designing study/sampling design, (iii) selecting AMR indicators, (iv) establishing analytical methods, and (v) developing data management/analytics/metadata plans. For each of these areas, the consensus among the scientific community and literature was reviewed and carefully considered prior to the development of this environmental monitoring program. The data produced from the SWAM effort will help develop robust surface water monitoring programs with the goal of assessing public health risks associated with AMR pathogens in surface water (e.g., recreational water exposures), provide a comprehensive picture of how resistant strains are related spatially and temporally within a watershed, and help assess how anthropogenic drivers and intervention strategies impact the transmission of AMR within human, animal, and environmental systems.

A Social Life Cycle Assessment as a Key to Territorial Development: A Study of the Hydrangea Crop in Colombia

Studying the social dynamics and development potential of agricultural enterprises is fundamental to promoting sustainable territorial growth. This study aims to assess the impact of growers of small and medium-sized hydrangea crops in the Colombian province of La Paz through a social life cycle analysis (S-LCA), shedding light on their fundamental roles as catalysts for regional development. For this purpose, the prioritization of actors and performance indicators is conducted following the methodologies proposed by the United Nations Environment Programme (UNEP) and the Global Reporting Initiative (GRI). Social variables are identified using the subcategory assessment method (SAM) to strengthen and assess indicators of low and high performance. Sixteen subcategories are qualitatively assessed, with 56% falling short of performance benchmarks, 25% meeting the benchmarks, 13% exceeding the benchmarks with proactive behavior, and 6% having potential with effort. Priority areas were identified as local employment and economic development contributions. This study highlights the significant impact of hydrangea production on territorial development, emphasizing the need to improve social security and health conditions for workers. Environmental actions to reduce agrochemical use are also advocated. This study proposes transforming the social life cycle analysis into an opportunity to evaluate actors’ performance and their contribution to territorial and sustainable development. It emphasizes the importance of assessing social impacts, ethical implications, and community relations throughout the crop value chain, with governance being a crucial aspect for territorial development. This study advocates the integration of these analyses into farm operations, serving as a benchmark for similar assessments across various agricultural activities.

Tourists' assessment of economic value, benefits and negative impacts of pedestrian walkways: Case-studies of the Paiva River (Arouca) and the Mondego River (Guarda) in Portugal

Hiking tourism becomes a popular wellness travel trend across the world. In recent years, we have witnessed the construction of walkways or boardwalks aiming to leverage the attractiveness of nature-based tourism destinations. This paper aims to assess the quality and economic value of two walkways/boardwalks in Portugal (MRW-Mondego River and PRW-Paiva River). A questionnaire applied to visitors at the entrances/exits of those linear walkways obtained 301 (MRW) and 188 (PRW) responses. In both case-studies, visitors provided high scores for the walkways' attributes and their overall satisfaction, which is positively correlated with their willingness to pay for a ticket to access the walkway (MRW- €4.56 and PRW- €6.31 respectively). This study also conducted a K-means cluster analysis for the Mondego RW sub-sample, that identified four different clusters: Cluster 1- (N = 8) Older and heavy spenders, a small segment of male visitors that spend a high amount of money during more than a 2-day stay in the region; Cluster 2- (N = 35) Heavy donators women, composed mainly by women who are willing to donate an higher amount for the conservation of the walkway; Cluster 3- (N = 62)- Average visitor whose members have a profile with characteristics similar to the average scores of the sample; and Cluster 4- (N = 189) Low spenders younger women, that plan their journey avoiding all the consumption moments and spending the lowest amount as possible (about €24). Based on the proposed theoretical framework and on the claims shared by visitors on the survey, this paper provides some recommendations for public decision-makers. Management implications•The local administration should reinvest the direct revenues from the walkways in new support infrastructures (e.g. accessibility, litter collection or the fire prevention/evacuation plan). They must also design an environmental education program for visitors to mitigate conflicts with local population.•The tourism operators must advertise and diversify the experiences, targeting the preferences of the four major visitors’ segments identified in the cluster analysis aiming to extend their stay in the region. The quality and variety of the restaurants should be improved and a new line of certified merchandising products is a potential source of shop owners’ revenues.

Heavy Metal(oid)s Contamination and Potential Ecological Risk Assessment in Agricultural Soils.

Soil pollution caused by heavy metal(oid)s has generated great concern worldwide due to their toxicity, persistence, and bio-accumulation properties. To assess the baseline data, the heavy metal(oid)s, including manganese (Mn), iron (Fe), Cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), lead (Pb), mercury (Hg), chromium (Cr), and cadmium (Cd), were evaluated in surface soil samples collected from the farmlands of Grand Forks County, North Dakota. Samples were digested via acid mixture and analyzed via inductively coupled plasma mass spectrometry (ICP MS) analysis to assess the levels, ecological risks, and possible sources. The heavy metal(oid) median levels exhibited the following decreasing trend: Fe > Mn > Zn > Ni > Cr > Cu > Pb > Co > As > Cd > Hg. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) suggested the main lithogenic source for the studied metal(oid)s. Metal(oid) levels in the current investigation, except Mn, are lower than most of the guideline values set by international agencies. The contamination factor (Cf), geo accumulation index (Igeo) and enrichment factor (EF) showed considerable contamination, moderate contamination, and significant enrichment, respectively, for As and Cd on median value basis. Ecological risk factor (Er) results exhibited low ecological risk for all studied metal(oid)s except Cd, which showed considerable ecological risk. The potential ecological risk index (PERI) levels indicated low ecological risk to considerable risk. Overall, the results indicate the accumulation of As and Cd in the study area. The high nutrients of the soils potentially affect their accumulation in crops and impact on consumers' health. This drives the impetus for continued environmental monitoring programs.

The Functionalization of Cotton Fabric Using Urtica dioica Microcapsules to Develop UV Protective Textiles

The World Health Organization (WHO) and the United Nations Environment Programme (UNEP) have highlighted the increased risk of skin cancer due to exposure to UV radiation. This emphasizes the importance of safeguarding the skin. Although sunscreens are commonly used for protection their high cost, the need for frequent reapplication, and pollution in coastal areas necessitate alternative solutions. Clothing also offers protection but requires additional application of dyes and finishes for prolonged effectiveness. The application of synthetic or natural dyes can enhance the UV protection properties of the fabric but Synthetic dyes contribute to pollution, while natural dyes lack durability. Addressing these challenges, this study focuses on providing a durable and sustainable solution for enhancing the UV protective properties of cotton fabric using Urtica dioica microcapsules based on RSM design. Urtica dioica plant extract serves as the core material for the microcapsules. Design Expert software 10 has been used for the study. It was observed through software that at 4.116% concentration of microcapsules, 3% concentration of binder and a curing temperature of 113.258 °C an optimum UPF with sufficient fabric properties can be achieved. On conducting the experiments on these optimum conditions UPF, tensile strength and bending length value were found to be 277.60, 14.89 N/cm2 and 2.00 cm respectively. Results indicate that cotton fabric demonstrates excellent UV protection properties even after the 20th wash cycle. This research contributes to the ongoing quest for fabric with UV protection, emphasizing both efficacy and sustainability compared to current synthetic alternatives available in the market.

Emotion Regulation in Psychology in Students

This research aims to find out how students' emotional regulation is studied in psychology. The period of emotional development of students in their teenage years is a transitional period that is very vulnerable and requires guidance to be able to control emotions. Emotions are a very dangerous mental disorder. We will discuss several important aspects, including the types of emotion regulation strategies commonly used by students, campus environmental factors that influence emotion regulation, and the impact of emotion regulation on students' psychological well-being and academic achievement. Students often face complex academic, social, and emotional stress in the campus environment, so their ability to manage their emotions is critical to their well-being and academic success. The method used in this research is a qualitative descriptive method. The subjects of this research were students at the Indah Medan College of Health Sciences. The results of the analysis using observation techniques. Through this research, it is hoped that there will be a better understanding of the role of emotional regulation in students' lives, as well as practical implications for the development of coaching and intervention programs in higher education environments.

A Study on a Health Impact Assessment and Healthcare Cost Calculation of Beijing–Tianjin–Hebei Residents under PM2.5 and O3 Pollution

Excessive fine particulate matter (PM2.5) and ozone (O3) are invisible killers affecting our wellbeing and safety, which cause great harm to people’s health, cause serious healthcare and economic losses, and affect the sustainable development of the social economy. The effective evaluation of the impact of pollutants on the human body, the associated costs, and the reduction of regional compound air pollution is an important research direction. Taking Beijing–Tianjin–Hebei (BTH) as the research area, this study constructs a comprehensive model for measuring the healthcare costs of PM2.5 and O3 using the Environmental Benefits Mapping and Analysis Program (BenMAP) as its basis. First, this study establishes a health impact assessment model and calculates the number of people affected by PM2.5 and O3 exposure using the health impact function in the BTH region. Then, the willingness to pay (WTP) and cost of illness (COI) methods are used to estimate the healthcare costs inflicted by the two pollutants upon residents from 2018 to 2021. The calculation results show that the total healthcare costs caused by PM2.5 and O3 pollution in BTH accounted for 1%, 0.7%, 0.5%, and 0.3% of the regional GDP in 2018, 2019, 2020, and 2021, respectively. Based on the research results, to further reduce these high healthcare costs, we propose policy suggestions for PM2.5 and O3 control in the BTH region.

Analysis of waste handling strategies for riverbanks communities

Waste management is essential to protecting the environment and minimizing its negative impact on human health and the ecosystem. The low participation of riverbank residents in maintaining and creating a clean environment in the river and its surroundings has prompted the Environmental Service to create a program called "River Maharagu" by holding river cleanliness competitions. This research aims to analyze the success of the Environmental Service program by formulating a strategy for handling waste from riverbank communities through a SWOT analysis. This research uses a qualitative approach with a descriptive type. The SWOT analysis results found that (1) Strategy (SO) encourages and facilitates stakeholders to collaborate with the Diaspora and universities to build and develop river ecotourism. (2) Strategy (WO) to build and increase the synergy of stakeholders and youth communities (Karang Taruna) in building and developing river ecotourism and coordinating with the Diaspora. (3) Strategy (ST): River management maintains self-sufficiency in collecting and transporting household waste and continues to motivate residents to dispose of waste properly. (4) (WT) The Environmental Service builds collaboration with universities in providing education to build awareness among riverbank residents.

Unveiling Social Dynamics in People's Perception of Raptors to Guide Effective Conservation Strategies

Ethnoscientific approaches offer valuable tools for exploring human–nature relationships, making them useful for developing effective conservation strategies. Raptors, which are birds of prey, face significant conservation threats worldwide, with human persecution being a leading factor in their population decline. Urgent conservation strategies are needed, particularly in regions of high raptor diversity like the tropical Andes. In this study, we employed semistructured questionnaires and logistic models to investigate how demographic factors, economic activity, and traditional knowledge shape people's perceptions of raptors in rural communities of the Ecuadorian Andes. These communities have historically experienced poverty and inequality, and our approach takes into account their local realities to provide conservation recommendations. Our findings reveal that traditional ecological knowledge provides a broad understanding of human–raptor relations, and that raptors are viewed as both providers of ecosystem services and disservices. Additionally, social demographics, such as gender and educational level, can influence people's perception of raptors. Based on these results, we can promote conservation actions from a local to global level. Ethnoecological approaches offer diverse conservation opportunities that can vary based on different local contexts. In addition to conventional measures such as environmental education programs, poultry management, and landscape preservation, it is essential to consider the political ecology of specific sites, particularly in regions of the Global South where poverty and inequality are closely intertwined with social and environmental injustices. As such, policy making to alleviate poverty and inequality in rural communities in Ecuador and other Andean countries; and science decolonization to make conservation more inclusive are crucial for human well-being and successful and lasting conservation actions for raptors and biodiversity.

Origin, Settlement, and Beliefs of the Bisukha and Bidakho of the Luhya Community-Kenya

This study interrogated the origin, settlement and the beliefs of the Bisukha and Bidakho sub-ethnic groups in the larger Luhya ethnic group. The paper has unravelled the etymologies of the Luhya, Isukha and Idakho terms. Furthermore, it has established the origins, migrations and settlements of the Bisukha and Bidakho, the differences and simulations that exist between them. The paper has also delved into the social-cultural economic and political institutions with their related beliefs, taboos and practices. The reviewed literature established a number of lacunae which this study has endeavoured to fill. The historical and ethnographic research designs were employed by the study. Oral interviews were used to collect the data, which was analysed within the environmental deterministic theoretical approach. The major finding is that; the various social, economic, cultural and political practices were done with the wisdom of maintaining the ecological set up for sustainability. That is, the pre-colonial Bisukha and Bidakho kept their ecological balance of give and take strategies that did not constrain the ecosystem.

Climate classification for Northeast Brazil using reanalysis data and the Absolute Aridity Index

The climate of the Northeast Region of Brazil (NEB) has been intensively studied and analyzed for climate classification. The aridity index of the United Nations Environment Programme (UNEP) (AIUNEP) has been used for this purpose, but without fully satisfactory results. The input variables needed for its calculation are precipitation and reference potential evapotranspiration (ET0). However, although rainfall stations recording routine measurements of precipitation are well distributed in the NEB, they do not provide the necessary variables for estimating ET0. Thus, interpolation is used to calculate ET0, but this can generate errors. Another objective climate classification approach is the Thornthwaite method, based on the determination of the moisture index (Im), whose calculation also requires weather station data. Thus, seeking to circumvent the problem of paucity of stations and improve the spatial distribution of information on meteorological variables in the NEB, the present work had as one of its objectives to validate reanalysis data from ERA5 of the European Center for Medium-range Weather Forecast (ECMWF) and the unified gauge-based analysis of global daily precipitation project of the Climate Prediction Center/National Oceanic and Atmospheric Administration (CPC/NOAA). After validation, climate classifications were developed for the NEB using the AIUNEP and Im. It was observed that the Thornthwaite climate classification overestimated the aridity in the NEB, while the IAUNEP tended to underestimate it. For this reason, a new climate classification index, called the absolute aridity index (Iab), was suggested, yielding satisfactory results.

CONTEXTUAL CORRELATES OF A SUSTAINABLE SCHOOL ENVIRONMENT IN ROXAS, ISABELA, PHILIPPINES

The study investigates the contextual correlates of sustainable practices at Anao-Kiling Elementary School, emphasizing human values as dominant factors in environmental stewardship. Specifically, this study aims to assess the level of environmental awareness, identify environmental issues, explore practiced behaviors, and examine challenges faced by students. Using a descriptive-normative research design, data was collected from 36 Grade 6 pupils through structured questionnaires. Frequency count and percentage distribution, weighted mean, Pearson-r correlation, and Chi-Square test were used to analyze the data. Results show that most respondents had access to smartphones, indicating a certain level of economic stability. Environmental care programs were implemented in many schools, and pollution and overpopulation were considered moderately serious issues. Both technology-based and non-technology-based activities showed a slightly aware level of environmental awareness. The findings also revealed that the respondents demonstrated practiced behaviors and exhibited human values like respect and honesty. Challenges faced included miscommunication about waste segregation policies and a lack of enthusiasm for clean-up activities. The statistical analysis indicated no significant correlation between environmental issues and human values, nor between environmental awareness and confronting environmental problems. Moreover, socioeconomic factors do not relate to the level of environmental care practices. To foster sustainable behaviors among students, regardless of socioeconomic status, it is essential to integrate environmental values and practices into school curricula. It is recommended that schools prioritize environmental education and enhance communication regarding waste segregation policies to promote a culture of environmental stewardship.

The uninformed budge yet the misinformed buck: performance information and citizen satisfaction

ABSTRACT This article examines the impact of performance information on citizen satisfaction in the context of an environmental information disclosure programme in the U.S. Through a survey experiment on a nationally representative sample, it finds that the impact depends on disconfirmation, which is the difference between performance information and citizens’ prior perceptions. However, the impact extends only to the uninformed, who do not have strong prior perceptions, but not to the misinformed, who confidently hold incorrect perceptions. With the misinformed consisting a large portion of the population, the findings have important implications for the use of performance information in public management.

Assessing the Interpretability–Performance Trade-Off of Artificial Neural Networks Using Sentinel Fish Health Data

A number of sentinel species are regularly sampled from the environment near the Oil Sands Region (OSR) in Alberta, Canada. In particular, trout-perch are sampled as a proxy for the health of the aquatic ecosystem. As the development of the OSR began before the environmental monitoring program was in place, there is currently no established measure for the baseline health of the local ecosystem. A common solution is to calculate normal ranges for fish endpoints. Observations found to be outside the normal range are then flagged, alerting researchers to the potential presence of stressors in the local environment. The quality of the normal ranges is dependent on the accuracy of the estimates used to calculate them. This paper explores the use of neural networks and regularized regression for improving the prediction accuracy of fish endpoints. We also consider the trade-off between the prediction accuracy and interpretability of each model. We find that neural networks can provide increased prediction accuracy, but this improvement in accuracy may not be worth the loss in interpretability in some ecological studies. The elastic net offers both good prediction accuracy and interpretability, making it a safe choice for many ecological applications. A hybridized method combining both the neural network and elastic net offers high prediction accuracy as well as some interpretability, and therefore it is the recommended method for this application.

Paternal microbiome perturbations impact offspring fitness

The gut microbiota operates at the interface of host–environment interactions to influence human homoeostasis and metabolic networks1–4. Environmental factors that unbalance gut microbial ecosystems can therefore shape physiological and disease-associated responses across somatic tissues5–9. However, the systemic impact of the gut microbiome on the germline—and consequently on the F1 offspring it gives rise to—is unexplored10. Here we show that the gut microbiota act as a key interface between paternal preconception environment and intergenerational health in mice. Perturbations to the gut microbiota of prospective fathers increase the probability of their offspring presenting with low birth weight, severe growth restriction and premature mortality. Transmission of disease risk occurs via the germline and is provoked by pervasive gut microbiome perturbations, including non-absorbable antibiotics or osmotic laxatives, but is rescued by restoring the paternal microbiota before conception. This effect is linked with a dynamic response to induced dysbiosis in the male reproductive system, including impaired leptin signalling, altered testicular metabolite profiles and remapped small RNA payloads in sperm. As a result, dysbiotic fathers trigger an elevated risk of in utero placental insufficiency, revealing a placental origin of mammalian intergenerational effects. Our study defines a regulatory ‘gut–germline axis’ in males, which is sensitive to environmental exposures and programmes offspring fitness through impacting placenta function.
