The Bali Tourism area represents complex environments where human activities intersect with natural landscapes, resulting in diverse land use land cover (LULC) patterns. However, understanding the dynamics of LULC in these areas and its interaction with land surface temperature (LST) remains a challenge. This study addresses this gap by investigating LULC mapping in urban tourist destinations and its influence on LST variations. The research problem focuses on exploring the relationship between various land cover types and LST variations. The main objective is to assess the interaction of LULC variations with LST in urban tourist environments. To achieve this goal, an integrated approach combining remote sensing techniques and machine learning will be employed. LULC mapping will utilize support vector machine (SVM) techniques with datasets sourced from multi-channel data, and spectral indices such as enhanced built-up and bareness index (EBBI) and normalized differences vegetation index (NDVI) derived from Landsat 9. The findings present a vivid overview of the research area, where built-up areas dominate, and spanning 108.61 km². Other land cover classifications include rice fields/grasslands, plantation/perennial plants, barren land, mangrove forests, shrublands, and water bodies, accurately mapped with high precision (overall accuracy = 88.52% and Kappa = 81%). Maximum LST values peak in built-up and barren areas, reaching 29.89°C and 29.28°C, respectively, while other land cover types exhibit comparatively lower values. Our analysis of the spectral index used in LULC classification uncovers a positive correlation with EBBI (R2 = 37.78%) and a negative correlation with NDVI (R2 = 10.69%, based on a substantial sample size of 67 869 pixels. We strongly urge future researchers to leverage high-resolution data for localized urban studies and stress the critical importance of enforcing stringent spatial planning regulations to safeguard green spaces, thus ensuring ecological equilibrium for future generations.

Organic food consumption can slow down environmental degradation by discouraging inputs and processes such as synthetic pesticides, fertilizers, and genetically modified organisms. A better understanding of factors that influence consumer behavior regarding the consumption of organic food in a developing nation such as Pakistan, particularly Generation Z. In this regard, this research explores the role of environmental values, environmental self-identity, and attitude towards organic food over Generation Z’s purchase intentions towards organic food. The statistical analysis of the conducted survey reveals distinctive results that provide a new direction in line with existing research. The study found that environmental values are not direct drivers of Generation Z’s attitude towards organic food. Rather, altruistic values like the wellbeing of others and society are important motivators. There are potential barriers such as affordability and availability of organic food that influence the purchase intentions of organic food. Interestingly, hedonic values, which drive joyful experiences, showed a positive impact over environmental self-identity, suggesting implications for marketers and practitioners to make Generation Z connect with nature through pleasurable activities, which eventually strengthen environmental consciousness. Finally, this research validates a positive influence of attitude towards organic food over purchase intentions, while challenges such as affordability and availability can weaken the purchase intentions among Generation Z consumers.
有机食品消费可以抑制合成杀虫剂、化肥和转基因生物等投入和加工，从而减缓环境退化。在这方面，本研究探讨了环境价值观、环境自我认同和对有机食品的态度对 Z 世代有机食品购买意向的影响。对所做调查的统计分析揭示了与众不同的结果，为现有研究提供了新的方向。研究发现，环境价值观并不是 Z 世代对有机食品态度的直接驱动因素。相反，利他主义价值观，如他人和社会的福祉，才是重要的推动因素。有机食品的可负担性和可获得性等潜在障碍也会影响有机食品的购买意向。有趣的是，推动快乐体验的享乐主义价值观对环境自我认同产生了积极影响，这为营销人员和从业人员提供了启示，让 Z 世代通过愉悦的活动与大自然建立联系，最终增强环境意识。最后，本研究验证了对有机食品的态度对购买意向的积极影响，而诸如可负担性和可获得性等挑战则会削弱 Z 世代消费者的购买意向。

Apeanut shell was used as a low-cost agricultural waste to eliminateacid blue 25 dye from an aqueous solution. Contact time, sorbate concentration, particle size, and sorbent mass were all investigated in batch sorption tests. The sorption process was investigated in terms of equilibrium and kinetics models. The sorption process is better in agreement with the pseudo-second-order model, with a greater regression coefficient value of 1 under all experimental conditions, according to adsorption kinetic results. The models of Freundlich, Langmuir and Temkin were used to describe the isotherms of adsorption, and equilibrium data was consistent with Freundlich isotherm with a higher regression coefficient value, R2. Based on the findings, the peanut shell is much more economical, cheap, viable, and very effective for the removal of acid blue 25 dye from aqueous solution.

In societies where consumers hold both green and materialistic values, which can be described as incompatible values, a conflict of values arises. Previous research on the green and materialistic value conflict has focused mainly on their negative consequences for consumer well-being. The antecedents of green and materialistic value conflict remain unclear. This research aims to determine the antecedents of consumers’ green and materialistic value conflict. Using a quantitative research strategy, data were collected following the survey method. The results of this research reveal that the effect of impulsive buying on the conflict between green and materialistic values is significant and positive, which means that impulsive buying reinforces the value conflict. Furthermore, the results show that the effect of mindfulness on the conflict between green and materialistic values is significant and negative, which means that mindfulness reduces the value conflict. These findings add substantially to our understanding of antecedents by adding new knowledge on the relatively under-researched antecedents of the conflict between green and materialistic values.

Strategic planning of university campuses (UC) aims to harmonize nature, humans, and architectural complexes, enhancing the positive university image through specialized green and recreation zones. Highly urbanized UC areas, particularly with nearby roads, encounter increased technogenic load and pose additional health hazards. The purpose of the paper is the evaluation of the environmental safety level of the UC recreational territories on the example of campuses of Kyiv universities, located nearby highly loaded roads, using a complex of express methods of analysis, mathematical modeling and criterion-based approach, considering the main green economy principles. The scientific novelty of the paper and the authors’ contribution is in the assessment of the environmental safety level of city-type UC recreational territories being under the significant technogenic load from vehicle emissions. Such express analysis methods as densimetry, viscometry, stalagmometry, conductometry, potentiometry and optical methods, and in particular, refractometric studies have been used to assess the impact of vehicle emissions. The mathematical modeling and computational experiment have been carried out for dispersion fields of the main vehicle emissions pollutants. Ecologically acceptable distances from the road considering the specifics of recreational territory have been determined using the integral index of technogenic load. Propositions for minimizing human health hazards and improving the system of environmental monitoring of such territories have been provided and substantiated. The study also confirms the positive effects of environmental management and green marketing principles synergy, benefiting both nature and humans as well as the university image. Obtained results can be used for the design and reconstruction of UC and their recreational areas, as well as for planning roads located nearby the campuses, improving traffic on them. It is also convenient to foresee the enhancement of the environmental activities in the student research work and create student communities for monitoring the UC environmental state and the development of eco-startup projects.

Multispectral satellite images are valuable sources of information for ecologists, agriculture climatologists, or environmentalists. Handling satellite images represents a challenge for better understanding the global change. The Belezma massif by its exceptional geographical position in the Mediterranean region of Northeast Algeria constitutes a fragile hot spot ecosystem with all the degradation factors that directly affect all landcovers. The objective of this study is to determine the contribution of satellite images in the detection of land cover global changes between 1986 and 2021 and landscape monitoring in Belezma region. The methodology adopted is the spatial remote sensing of the evolution of forest stands and the change in land cover, from the processing of Landsat images (L05 TM 1986, L07 ETM+ 2001 and L08 OLI_TIRS 2021) and sampling work for confrontation with the reality on the ground. The outcomes of this investigation demonstrate a general regression rate in the natural vegetation cover that the cedar forest, the steppe, and the wetlands lost 42%, 49%, and 97%, respectively, of their areas between 1986 and 2021, while the degraded and anthropic occupations have increased in favor of market gardening, bare soil, urban areas, and arboriculture by 836%, 158%, 131%, and 50%, respectively, over the same period. This study made it possible to identify and analyze 13 main land uses and plant formations over a period of 35 years, which can be used as a decision-making aid model for the managers of these territories.

Sustainable mangrove management plays a pivotal role in advancing various sustainable development goals (SDGs). These encompass poverty and hunger eradication, fostering livelihoods and economic growth, countering the impacts of climate change, and protecting biodiversity. To investigate this matter, our study employed participatory rural appraisal (PRA) and focus group discussion (FGD) techniques. The study engaged with local government officials, fishermen, farmers, non-governmental organizations, women leaders, community leaders, and the general public actively involved in mangrove forest regions. The purposive sampling method ensured a representative sample. A comprehensive analysis was conducted, integrating SWOT analysis and the analytical hierarchy process (AHP). The findings revealed several key strategies: promoting the development of the potential of economically and sustainably valuable mangrove ecosystems through environmentally friendly planting and harvesting; empowering communities through farmers, fishermen, and women’s groups to generate household-scale mangrove-based industries; providing all necessary facilities and infrastructure for mangrove ecotourism visitors; expanding the role of non-governmental organizations (NGOs) in improving community awareness and knowledge on the management of mangroves; and providing training to increase the diversification of mangrove economic products.

Phenolic compounds have gained international interest due to their carcinogenic, toxic, and bioaccumulative properties, causing adverse effects in both animals and humans. As a result, there is a growing interest in finding alternative and eco-friendly treatment routes for phenol by exploring new microbial cultures with potential adaptation and biodegradation capabilities. In this study, the phenol removal efficiency of Yarrowia lipolytica YQ22 under laboratory conditions was determined. The YQ22 strain was obtained from diesel samples from a fuel station in Trujillo, Peru, isolated through serial dilutions on Sabouraud agar, and identified through its morphological characteristics using microscopy and molecular analysis by polymerase chain reaction of the ribosomal DNA internal transcribed spacer (ITS) and 5.8S regions. In the treatment, the effect of pH (5, 6 and 7) and temperature (25°C, 30°C and 35°C) on phenol removal with 2% (v/v) inoculum of Yarrowia lipolytica from 48-hour growth was evaluated. Phenol concentration was measured by high-performance liquid chromatography. A maximum phenol removal percentage of 61.18 was obtained for YQ22 at 30°C, pH 5 and 120 rpm during 48 hours. These findings demonstrate the ability of Yarrowia lipolytica to remove phenol and suggest its potential use in the field of bioremediation of phenolic compounds and their derivatives.

As a result, there is a growing interest in finding alternative and eco-friendly treatment routes for phenol by exploring new microbial cultures with potential adaptation and biodegradation capabilities. In this study, the phenol removal efficiency of Yarrowia lipolytica YQ22 under laboratory conditions was determined. The YQ22 strain was obtained from diesel samples from a fuel station in Trujillo, Peru, isolated through serial dilutions on Sabouraud agar, and identified through its morphological characteristics using microscopy and molecular analysis by polymerase chain reaction of the ribosomal DNA internal transcribed spacer (ITS) and 5.8S regions. In the treatment, the effect of pH (5, 6 and 7) and temperature (25°C, 30°C and 35°C) on phenol removal with 2% (v/v) inoculum of Yarrowia lipolytica from 48-hour growth was evaluated. Phenol concentration was measured by high-performance liquid chromatography. A maximum phenol removal percentage of 61.18 was obtained for YQ22 at 30°C, pH 5 and 120 rpm during 48 hours. These findings demonstrate the ability of Yarrowia lipolytica to remove phenol and suggest its potential use in the field of bioremediation of phenolic compounds and their derivatives.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"31 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140737312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to identify the geological and lithological structures of mine land, determine the slope stability of the land, and determine the sustainability of landslide management in Kutai Kartanegara Regency, East Kalimantan, Indonesia. This present research was conducted in Samboja and Sebulu sub-districts, Kutai Kartanegara Regency, East Kalimantan, Indonesia. Data collection concerning the geological structure, lithology, and sustainability of coal mine landslides was carried out. Rock data, such as its physical and mechanical properties, were taken from complete coring drilled and then analyzed in a geomechanics laboratory. This procedure was carried out in three locations, with the first and second samples collected in the Kampungbaru Formation representing the youngest formation. In addition, the third taken in the Pulubalang Formation represents the oldest coal-bearing formation. The data relating to the avalanche condition were collected through surveys, interviews, and filling out questionnaires using a purposive sampling method. The respondents were 13 mining engineering heads from various mine sites in Kutai Kartanegara Regency, three mining environmental experts, and four academics. The results showed that of the 50-joint data, those with potential positions for landslides were located at N333°E/61° and N110°E/74°. The most dominant lithology in the study area was claystone, followed successively by sandstone, siltstone, and shale, with a specific gravity between 2.55 and 2.66. The dominant claystone indicated a relatively prone area. Meanwhile, the strength of the mechanical properties of the rock (direct shear) cohesion ranged from 17.80 and 174.53 kPa, with shear angles ranging from 10.88° to 42.01°. Based on the design of the slope stability in the three locations, this study demonstrated the maximum slope angle ranging from 29° to 37°, a height of 50.17 to 70.16 meters, a single slope height of 10 meters with an angle ranged from 32° to 44°, and a factor of safety (FOS) ranging from 1.326 to 1.452 with stable conditions. Multi-dimensional scaling (MDS) simulation results of the sustainability status comprised of a total of 49 attributes derived from five dimensions, namely ecological, economic, social, law, institutional and technological, demonstrated a score fell of 50.01. Furthermore, to increase the sustainability score, this study identified some sensitive factors as follows: condition of the slope of the mine slope, MSME business of residents, role of NGOs in mine landslides, concern of pit supervisory personnel for mine landslides, and mastery of mine landslide technology. Hence, the projection sustainability score increased to 82.00, which was achieved in the good category.
