Modeling soil retention, erosion potential, and sedimentation risk using the InVEST SDR model
type: item
description: This study conducts an examination of the Ilam watershed, utilizing the InVEST and SDR models to assess soil retention, erosion, and transport. It incorporates factors like rainfall erosivity, soil erodibility, DEM, land use, vegetation, and conservation practices to explore the complex interplay between ecosystem services (ES) and disservices. The study found that the average soil retention in the watershed is 94.5 tons/ha/year, the average erosion potential is 62.8 tons/ha/year, and the average sediment transport is 10.5 tons/ha/year. Forest areas retain a significant portion of sediment (60%) with low discharge (13%), while agricultural and urban regions contribute more to erosion. This highlights the importance of integrating ES into land management strategies to mitigate environmental degradation. The study highlights the crucial role of ES in maintaining ecological balance and supporting human well-being. It advocates for innovative policies and customized solutions to mitigate land use impacts on soil conservation and sediment retention, thereby fostering awareness among managers and decision-makers for more sustainable land use planning.

Spatial pattern and its driving forces analysis of soil available nitrogen, phosphorus, and potassium in semi-arid grassland surface coal mining areas
type: item
description: Mining activities not only provide a large amount of material basis for socio-economic development but also cause great damage to the environment. It is of great significance to study the spatial variation characteristics of soil Available Nitrogen (AN), Available Phosphorus (AP), and Available potassium (AK) in mining areas for land reclamation and ecological protection. Currently, research on soil AN, AP, and AK in mining areas is lacking in large-scale survey, sampling, spatial pattern, and driving force research for surface coal mines in semi-arid grassland areas, and it is not possible to comprehensively grasp the distribution characteristics and driving forces of soil AN, AP, and AK in surface coal mines. Given this, this study took the Shengli Coal Field in Xilinhot City, the hinterland of Xilingol Grassland, as an example to study the spatial pattern and driving forces of soil AN, AP, and AK in the semi-arid grassland surface coal mining areas. The results showed that: (1) There was no strong spatial correlation among AN, AP, and AK in the soil of the study area, and the spatial pattern heterogeneity was strong. The content of AN, AP, and AK in southeast soil was relatively low. (2) The influence degree of each factor on the spatial pattern of AN was ranked as follows: NDVI > Agriculture > Water > Town > Mining > Industry; (3) The influence degree of each factor on the spatial pattern of soil AP was ranked as follows: NDVI > Mining > Water > Industry > Town > Agriculture; (4) The influence degree of each factor on the spatial pattern of soil AK was ranked as follows: NDVI > Town > Agriculture > Water > Mining > Industry; (5) The interaction between two factors presented two relationships: nonlinear enhancement and dual-factor enhancement. The interaction between various factors was higher than that of a single factor.

Enhanced nitrogen removal and sludge characteristic in aerobic SBR by simultaneous nitrification and denitrification bacteria
type: item
description: Four efficient heterotrophic nitrification and aerobic denitrification (HN-AD) strains were applied in sequencing batch reactors (SBRs) via two bioaugmentation strategies to enhance the nitrogen removal and sludge characteristic. Synthetic domestic wastewater with NH4-N concentrations of 30~50 mg L–1, was treated in three SBRs, with DO maintained at 4±0.5 mg L–1. Compared with the control (crude activated sludge), bioaugmentation improved TN removal by 7% averagely, increased nitration rate by 0.54 mg g–1 h–1, and reduced sludge volume index at 30 min (SVI30) by 3.5~14.7 mL g–1. The maximum TN removal efficiency reached 50.37% with effluent TN concentration of 14.64 mg L–1, meeting China’s Class 1A discharge standard (TN ≤ 15 mg L–1). SBR started by bacterial suspension without activated sludge exhibited high adaptability to low carbon/nitrogen ratio, achieving 35% TN removal at C/N = 3 (vs <10% in control), with <5% MLSS fluctuation versus 30% decline in control. Microbial community analysis revealed Saccharibacteria dominance (15.34% vs control’s 8.48%) coupled with 7.6% reduction in filamentous Saprospiraceae (12.78% to 5.18%), collectively explaining the enhanced nitrogen removal and sludge settleability. This study provides the first evidence of granular sludge formation via HN-AD bacterial coaggregation under low C/N conditions, offering a novel strategy for energy-efficient wastewater treatment.

Motivation to pangolin conservation among Gen Z: applying the extended Theory of Planned Behavior
type: item
description: The study explores the factors influencing pangolin conservation intentions among Gen Z using the extended Theory of Planned Behavior (TPB). Despite ongoing conservation efforts, pangolins remain one of the most trafficked animals globally, facing severe threats from illegal wildlife trade. To address this, the research investigates the roles of attitudes, subjective norms, and perceived behavioral control, along with knowledge and experience, in shaping conservation behaviors. A quantitative approach was employed, utilizing a structured questionnaire to gather data from 377 respondents. Partial Least Squares Structural Equation Modeling (PLS-SEM) was applied for data analysis. The results show that subjective norms and perceived behavioral control are the most significant predictors of behavioral intentions, whereas attitudes, knowledge, and past experiences related to wildlife conservation or pangolins have a relatively weak influence. While they still have a positive effect, these factors do not influence the intention to engage in pangolin conservation behavior as strongly. These findings suggest that conservation campaigns should focus on leveraging social influences and enhancing individuals’ perceived control over their actions rather than solely increasing factual knowledge.

Changes in land use conflict and zoning optimization in rapidly developing mountainous cities: a case study of Guiyang, China
type: item
description: Mountainous cities, influenced by complex human activities and terrain, face severe land use conflict issues. However, the spatiotemporal characteristics of land use conflict changes and the scientific questions regarding their management in rapidly developing mountainous cities remain unresolved. Therefore, Guiyang, a typical mountainous city in China, was chosen as the study area. With the support of ArcGIS technology, this research analyzed land use conflict changes and conducted zoning optimization. The study reveals a rapid intensification of land use conflicts, with high conflict areas increasing by 369%, while moderate, general, and low conflict areas declined. The conflict between production and living spaces is the predominant one, expanding by 385%. Additionally, high conflict areas between production and ecological spaces rose by 760%. Integrating land suitability, conflict, and functional differences in zoning optimization enhances core functions, mitigates conflicts, and guides land use management. The results are valuable for optimizing land use patterns and promoting healthy urban development in mountainous cities.

The impact of lakeshore modifications and constructions on visual landscape quality: a mixed methods study
type: item
description: Lakeshore areas continue to be threatened by increasing human activities and land use. Development and large construction projects in lakeshore areas affect both the lake’s ecological condition and its landscape quality and aesthetics. To minimize and prevent the occurrence of significant visual impacts, it is important to understand and evaluate the magnitude of damage and the factors contributing to such impacts from development activities. In this study, a mixed methods approach is used to assess the visual impact of modifications and constructions on the lakeshore landscape. This includes (1) an objective landscape indicator-based assessment method to measure the extent of construction and modification impacts on the visual landscape, and (2) a visual perception-based assessment method to capture receptors’ evaluations of the visual landscape changes and visual impact factors on the lakeshore. Integrating the results from both methods yields a comprehensive assessment of visual impact. The results of both assessment methods indicate that the visual quality of the lakeshore landscape declined significantly during the construction phase. In addition, this study concludes that this mixed approach to visual impact assessment has greater advantages than a single approach and provides more dimensional information, criteria, and perspectives.

Study on suitability assessment method of vegetation restoration species in disturbed sites of transmission line engineering construction
type: item
description: Screening species that can adapt to the disturbed habitats resulting from transmission line construction is of great practical significance for the ecological restoration of primary vegetation degradation caused by such construction. Therefore, a suitability evaluation method for vegetation restoration species in disturbed areas of transmission line engineering construction is studied to improve the ecological restoration. Based on the principles of stability and durability, adapting to local conditions and trees, and comprehensive and dominant screening, an index system for evaluating the adaptability of vegetation restoration species is established. Determine the subjective weight of evaluation index by G1 method and G2 method. The objective weight of evaluation index is determined by improving entropy weight method and deviation method. Through the optimal combination weighting method, the final evaluation index weight is obtained by combining subjective weight and objective weight. Using cloud model combined with index weight to calculate the certainty of each index. According to the principle of maximum certainty, the evaluation grade corresponding to the maximum certainty is selected as the final suitability evaluation result. The experiments have demonstrated that the suitability evaluation index system of this method exhibits high reliability, and it can effectively determine the weights of the suitability evaluation indices and complete the suitability assessment for vegetation restoration species. Among these species, Elymus chinensis, Panicum miliaceum, Brassica napus, arugula, and rye exhibit the most promising ecological restoration effects.

Landscape change and perception along historical railway: the case of Yunnan-Vietnam Railway, China
type: item
description: Against the background of environmental change, this study investigates the relationship between landscape changes and perceptions along the historical railway using a combination of Historical Geographic Information Systems (HGIS) and Fuzzy-set Qualitative Comparative Analysis (fsQCA). After quantifying the changes by GIS, the research aims to understand how different types of landscape changes affect physical, psychological, and cultural perceptions among locals. By integrating historical maps with remote sensing data and questionnaire, the study provides a comprehensive analysis of landscape evolution over time. The findings reveal that cropland and urban areas both showed significant increases along the railway; forest and water body both decreased over 70 years. The presence of forest change led to significant cultural perceptions and cropland change influenced the psychological perceptions of landscape. This research contributes to the understanding of the interplay between landscape change and human perception, offering valuable insights for sustainable landscape management and heritage conservation.

Determination of suitable recreational areas in Adana Province Cukurova district by AHP technique
type: item
description: Recreation is people’s whole activity to regain their lost energy. In urban recreation areas, today’s people can escape city life and reach themselves and nature at some point. In this context, the distribution, size, and accessibility of recreation areas in cities gain importance. The research aims to determine potential recreation areas by considering the natural and physical characteristics of the Adana Province Cukurova district. The criteria and importance weights of the criteria related to the natural and physical characteristics of Cukurova district, which is the research area, were determined by Analytic Hierarchy Process (AHP) technique. The data layers of the criteria were overlapped using the “Weighted Linear Combination Technique” in ArcMap program using the importance weights and a map of potential recreation areas was created. The results show that 2.6% of the region has low, 72.2% has medium, and 25.2% has high recreational potential. The western part of Seyhan Dam Lake has been identified as the most suitable area for recreation. Providing a holistic green space system will enable the development of the city’s natural potential. In addition, the areas proposed to be planned as recreational areas will contribute to urban ecosystem services and improve the quality of urban life. To define recreational suitable areas provides effective and quick solutions to manage urban sprawl on ecological. (Referee 1).

Spatial-temporal evolution of land ecological health and influencing factors in China's ecological civilization pilot area
type: item
description: It is crucial to assess the land ecosystem health (LEH) in China’s national pilot zones (NPZ) for ecological conservation and identify the primary factors that impact it. This is crucial for developing China’s ecological civilization and fostering sustainable, eco-friendly economic development. The study utilizes the pressure-state-response (PSR) and environment-economy-society (EES) model, relying on the panel data of 11 cities of Jiangxi in the NPZ for ecological conservation from 2005 to 2020, measuring the LEH in the national ecological civilization pilot zone using the comprehensive index evaluation method. The main contribution of this study is to optimize the land ecological health index system, construct an improved PSR-NES theoretical model that is more suitable for NPZ, reveal the spatial and temporal evolution characteristics of LEH in NPZ from the city scale, and refine the key driving factors. Results show that (1) The LEH exhibited a general shift from a state of “less healthy” level to the “healthier” level; (2) Differences in LEH evolution in different cities. The overall trend of “north to south and east to west” is gradually improving. (3) Urbanization has a strong role in the promotion of LEH, and economic development shows a significant dampening effect.

Regeneration and characterization of spent bleaching earth: recycling in the corn oil bleaching process
type: item
description: The spent bleaching earth (SBE) is a solid waste from the edible oil refining industry which generates soil contamination was successfully recycled after deoiling through an extraction process using different organic solvents, followed by heat treatment. In the current study, the effects of factors, such as solvent to (SBE) ratio [1:1–5:1], temperature [20–40 °C], and stirring time [30–60 min] on the efficiency of extracted oil were investigated by maceration method. Characterization analyses (SEM, XRD, XRFA and TGA) were carried out to compare the characteristics of samples. The best oil extraction efficiency was obtained at the highest level of solvent to (SBE) ratio (MR = 5) at 30 °C temperature and at the 45 minutes stirring time this condition led to 72.82% oil extraction yield. The corn oil bleaching efficiency using the SBE treated at optimal condition and heated at 400 °C was improved to 84.75%.

Acetone, xylene and ammonia removal enhancement in the biofilter packed with steam modified biochar
type: item
description: The present study evaluated short-time effect of steam modified biochar with rhamnolipid solution on the removal of different volatile organic and inorganic compounds (acetone, xylene, ammonia) in biofilter with capillary system. Modification of pine wood biochar with steam governed better treatment of pollar acetone and ammonia compounds from the air stream with removal efficiencies of 93% and 96%, respectively. It was related to biochar’s higher average capillary radius, moisture content and lower air velocity. However, removal of xylene was much lower and reached 72% in the case of modified biochar. It can be explained by its higher Henry’s constant, hydrophobicity and non-polarity.

The practices of public spaces in traditional neighborhoods: case of the Argoub district, city of M'sila-Algeria
type: item
description: Public space seems to have become one of the key elements of local development policies. As such, our study will focus on a traditional neighborhood called Argoub located in the center of the city of M’sila in Algeria, the public spaces of this neighborhood have long been the fundamental structure and the filter of reading of the neighborhood, they have deteriorated and to remedy this problem, the Observation shows that the public space in this district is distorted and its use for heterogeneous purposes than those previously planned, but this diversion of use continues to fragment the public space and reduce it to an obstructed space. The local authorities have carried out limited urban improvement of these spaces to perpetuate and improve their urban quality. This study aims to measure the quality of these spaces, to clarify the notion of traditional public space, and to identify its different practices. For this research, we chose as a methodology recurring observation reinforced by situational observation, while taking into account the urban and historical context of this district. Without permanent control from local authorities, illegal interventions by residents in the spaces in question have completely changed the alleys into stifling spaces used only for transition and not for social interaction. Despite the limited intervention of urban planning services to safeguard the urban fabric network and revive traditional public spaces, the ongoing change practices by residents have had a negative influence on the urban landscape of the neighborhood in general. As such, we will be faced with the following challenges: security, physical and visual quality, and economic attractiveness must, at the end of planning, require a real global reflection on these different urban forms so that their management is coherent and thoughtful. In this regard, the obvious question is: what practical measures should be taken to respond to the problems of landscape and spatial qualit…

Utilization of recycled carbide as adsorbent for adsorption of dyes and COD from textile waste
type: item
description: This study assessed the potential of carbide waste (CW), a by-product of the welding industry, as a cost-effective adsorbent for removing dyes and COD from textile wastewater. CW was prepared through drying, filtering, and shaping into 2 mm-thick tablets (3 mm diameter), followed by heating at 150 °C for 120 minutes. Characterization using FTIR and SEM-EDX confirmed functional groups like hydroxyl and carbonyl and significant surface morphological changes. Batch experiments achieved maximum color and COD removal efficiencies of 94.48% and 96.73%, respectively, at 75 g adsorbent dosage and 150 min contact time. Freundlich isotherm (R² = 0.9918 for color) indicated heterogeneous adsorption, and kinetic studies fit a pseudo-second-order model. The process was exothermic, spontaneous, and governed by physical adsorption. Regeneration trials showed COD removal efficiency remained 90% after four cycles. These findings establish CW as an efficient, sustainable adsorbent with promising environmental and industrial applications for textile wastewater treatment.

Landscape management for disaster-prone cities: disaster resilient park proposal
type: item
description: Elazığ is a disaster-prone city due to its geological structure, proximity to fault lines, and similar reasons. As part of the study, a disaster-resilient green space model applicable to the city has been developed. The study examines how green spaces should be planned and designed to be used in disaster situations. The methodology of the study consists of three phases. (1) The city of Elazığ was analyzed in terms of disasters. (2) UAV and GPS CORS devices were used to collect data in the area designated as the disaster park and three-dimensional spatial analysis was performed. (3) The disaster park was designed according to the data obtained. The results show that Elazığ is frequently affected by disasters. Therefore, it is understood that the city needs a disaster-resistant green system. Suggestions for the design of disaster parks and their inclusion in the landscape management of disaster-prone cities have been developed.

Prediction of the anti-carbonation performance of concrete based on random forest – least squares support vector machine model
type: item
description: Concrete carbonation is a critical factor influencing the durability and longevity of concrete structures, particularly in urban environments. Traditional methods for predicting the anti-carbonation performance (ACP) of concrete often lack precision and fail to account for complex interactions between influencing factors. In this study, a novel hybrid model combining random forest (RF) regression with a least squares support vector machine (LSSVM) is proposed to enhance the accuracy of ACP predictions. The RF regression is utilized for feature selection, identifying the most significant factors affecting ACP and optimizing the input features for the LSSVM model. Our hybrid model is validated against a comprehensive dataset, demonstrating superior performance in predicting concrete carbonation resistance compared to conventional methods. Quantitative results show that the RF-LSSVM model achieves a root mean square error (RMSE) of 5e–5 and a high coefficient of determination (R-squared) of 0.999, indicating robust predictive capability and accuracy. The main novelty of this work lies in the integration of RF and LSSVM to create a robust, accurate, and practical tool for assessing the durability of concrete structures.

Study on the polymeric treatment with rice husk silica on sisal fiber in cementicious composites
type: item
description: This research evaluates how treating sisal fibers with expanded polystyrene (EPS) and rice husk silica (RHS) affects their absorption capacity, tensile strength, and adhesion when used in Portland cement matrices. The study on sisal fibers treated with EPS and RHS polymers found that the treatment significantly reduced water absorption by 70%, from 84.67% for untreated fibers to 15.18% for treated ones, due to the hydrophobic nature of EPS. Optical microscopy revealed an irregular polymer layer on the fibers, which, while improving dimensional stability, could impair fiber-matrix interaction. Despite these improvements, the treatment did not notably enhance the mechanical properties of the fibers, as the breaking strength remained similar to untreated fibers, and the rupture displacement slightly decreased.

Sustainable recovery plan for an urban-rural community affected by the Fundão Dam disaster in Brazil
type: item
description: The rupture of Fundão Dam spilled contaminated tailings across the Doce river basin, severely damaging municipalities such as the urban Barra Longa and the rural Gesteira. The wave of tailings led to the sediment deposition in rivers margins, causing the loss of riparian forests and cropping areas. Sediment analyses confirmed the presence of toxic compounds (sodium and ether amine) and a very low fertility. In consequence, there was a sharp decline in agro-pastoral production in Gesteira, leading to land abandonment and rural exodus. In the urban area of Barra Longa, the wave of tailings damaged the urban floodplain and the square, which were rehabilitated using grey infrastructure. Alternatively, we proposed a new landscape recovery plan for both Barra Longa and Gesteira based on Nature and Community-based solutions that contemplate the inclusion of green infrastructure, the remediation of toxic compounds, the restoration of soil fertility, permeability and stabilization, riparian forest rehabilitation and the recovery of agro-pastoral productivity, ultimately aiming at reducing the flood risk and land abandonment.

A SDGs-oriented evaluation of the ecological sustainability of international horticultural exposition sites in Chengdu, China
type: item
description: This study employs the AHP-entropy weight methodology and a spatial econometric regression model to evaluate the ecological sustainability and its changes between the current situation and the planning scenario at the 2024 Chengdu International Horticultural Exposition in China. The results indicate a notable shift: a reduction in areas of low and highest sustainability and significant expansion in medium levels, which spans 34.04 hm2. The transformation of village settlements, wastelands, and farmland into exhibition gardens and water bodies is shown to bolster medium-level ecological sustainability by enhancing rain and flood security and mitigating the risk of flood disasters. The development of Integrated Service areas will lead to an increase in impervious surfaces. The anticipated forest loss, along with declines in vegetation coverage, three-dimensional green volume, and vegetation carbon stock will adversely affect the highest sustainability. The study identifies a robust correlation between ecological sustainability level and quantitative indicators, with regression coefficients ranging from 0.5875 to 0.7148. This analysis provides policymakers with valuable insights and directions for the sustainable planning and development of mega-events.

Automatic monitoring of treated water released from wastewater treatment plants using model-based clustering with density estimation
type: item
description: One of the most promising efforts to fight against the water scarcity threat is to reuse the treated water released from WasteWater Treatment Plants (WWTP). The objective of this paper is to propose an integrated approach for continuously evaluating the performance of wastewater treatment plants (WWTPs), with a focus on treated wastewater quality assessment and reuse of treated water for beneficial purposes like irrigation, aquarium, groundwater recharge, and in river water discharge based on pollution level in treated water. This paper implemented a model-based clustering with density estimation to generate the non-overlapped clusters to categorize the clusters. Cluster analysis using the Euclidean distance resulted in three clusters labeled under a specified category of water polluted: non-polluted, lightly polluted, highly polluted or slightly polluted. Unlike standard clustering algorithms like K-means, hierarchical that produce optimized clusters in statistical terms that deviate from naturally categorized clusters, model-based clustering with density estimation operates on the assumption that each data object originates from the mixture of underlying probability distributions. Water quality parameters like suspended solids (SS) have been considered for the analysis. Our experimental results conclusively show the polluted levels of wastewater from WWTP using a model-based clustering approach. The Dataset used in this work has been derived from the wastewater treatment plant located in Manresa, a town of 100,000 inhabitants near Barcelona (Catalonia). The plant treats a flow of 35,000 m3/day, mainly domestic wastewater, although wastewater from industries located inside the town is received in the plant too. In this research, the plant’s behavior over 527 days are under consideration. Model-based density clustering algorithm discovers 3 clusters, with half lying in size range of 14–89 and a maximum size of 352. With the help of natural clusters generated, our re…

An assessment of an urban protected area through a space syntax approach: the case of Ordu, Turkiye
type: item
description: Traditional architecture, preserved and integrated into urban life, has the potential to become a point of attraction for cities and contribute to their image. The aim of this study is to analyse the configurational characteristics of the urban conservation area and its immediate surroundings, which constitute the historical core of the city of Ordu, and the general condition of the registered architectural examples in the area. The evaluations of the spatial configuration are based on the analyses of connectivity, global and local integration, which are the basic parameters of the spatial sequence method. As a result of the study, it can be seen that the two main traffic arteries of the area, Sıtkı Can Street and Dr Osman Hilmi Memecan Street, have the highest sequence values. Although it can be seen that Sıtkı Can Street, one of these traffic arteries, is more advantageous than other streets in terms of the registered civil architecture stock in the area, it is important that restoration processes should be implemented as soon as possible in order to ensure structural and historical continuity and not to lose the registered civil architecture examples located in different parts of the study area.

Recognition and optimization of landscape genes in traditional settlements: a case of Meishan area
type: item
description: Traditional settlement landscapes provide vital ecosystem services and represent significant cultural heritage, making their preservation crucial for national cultural development and rural revitalization. This study focuses on Meicheng Town in the Meishan area, utilizing landscape gene theory to classify and identify cultural landscape features. By integrating the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE), the study develops a landscape gene sorting index system, systematically evaluating 16 sub-categories of landscape factors. The results highlight topography and building decoration as dominant features that should be prioritized for preservation. However, areas such as building materials, traditional culture, and folk customs require significant improvement. Additionally, the river and road landscapes present opportunities for enhancement to strengthen the town’s cultural identity and aesthetic quality. The study provides practical recommendations for optimizing Meicheng Town’s landscape, balancing the preservation of traditional elements with modern development needs. This approach addresses gaps in the literature on settlement landscape genes and offers strategies for sustainable rural cultural landscape development.

The effect of nature-based landscape design on human health and well-being: a thematic synthesis
type: item
description: Population growth, high-density living situations, and rapid urbanization lead to environmental change that affects ecosystems, human behavior, and well-being. To design health-promoting urban landscapes, it is necessary to conduct more detailed studies of landscape features. However, there is a lack of review articles discussing specific approaches and factors of landscape design for human well-being in evidence-based landscape research. Therefore, this review aims to explore the research trends and future studies’ direction by adopting a thematic analysis approach. Using ATLAS.ti 23 software, we analyzed 40 literature articles on landscape design and human well-being published between 2018 and 2022. The article attribute findings show the research trends on the topic. Six main themes emerged from the subsequent qualitative analysis: (1) Human-nature Interactions, (2) Health-promoting Design, (3) Integrative Strategies, (4) Landscape Intervention, (5) Perceptions and Restorativeness, and (6) Sustainability. The resulting framework serves to guide landscape designers, urban planners, and researchers to improve the effectiveness of public social, physical, and mental health with feasible measures and design approaches.

Investigating the influence of urban green spaces on urban heat island mitigation – taking four districts in Shijiazhuang as an example
type: item
description: The primary objective of this scholarly investigation is to elucidate the intricate interplay between the urban heat island (UHI) effect and municipal green spaces. The geographical focus includes the four areas with the highest urbanization rate in Shijiazhuang, China. To conduct this survey, ECOSTRESS remote sensing imagery was acquired during distinct temporal intervals–morning, midday, and evening. The data were collected using the equal-scale city blocks performed by the OpenStreetMap urban network and ECOSTRESS remote sensing images at different times (morning, noon and evening). Surface temperature inversion of satellite images was performed using ArcGIS 10.7 software to obtain surface temperature. The overarching aim was to discern the nuanced impact of urban parks on the surface temperatures of their proximate environs during the summer season. The findings of this investigation revealed that, in order to effectively ameliorate the discernible heat island effect (SUH), rejuvenation initiatives ought to be directed toward sites maintaining a distance from green spaces within the range of 160 to 370 meters. Furthermore, augmentation of green space configurations is recommended in vicinities characterized by building densities falling within the range of 0.2 to 0.3. Notably, in locales marked by high building density, park layouts should adhere to a more regularized design during the renovation process. Additionally, it is advisable to ensure that the spatial separation between distinct urban parks exceeds 900 meters. These empirical insights are poised to enhance the comprehension of urban planners regarding the intricate dynamics through which urban parks exert influence on municipal surface temperatures. Furthermore, the discerned patterns furnish pragmatic guidance for mitigating the heat island effect, thereby offering invaluable recommendations for urban planning endeavors.

GIS based ground water assessment of Nilakkottai Taluk, Tamil Nadu, India: hydrogeochemistry and statistical perspective
type: item
description: Water quality is imperative for drinking and agriculture purposes in order to meet the increasing requirements for water. The systematic assessment of groundwater quality in Nilakkottai Taluk, Dindigul District, Tamil Nadu, was performed. In order to ascertain the quality of the study area’s groundwater, various water quality indices, spatial distribution maps, multivariate statistical analysis, and hydrofacies diagrams have been contemplated. 40 samples were collected and analysed for 20 water quality parameters, using the standard techniques. The quality results of the irrigation analysis showed that the groundwater samples were satisfactory for agricultural use. The deduction of four principal components denotes that hydrogeochemical processes and anthropogenic inputs were the main controlling factors. The durov plot demonstrated the dominance of Ca-HCO3 type groundwater, indicating a weathering process through fresh water recharge. This study insisted that majority of the samples satisfactory for crop yield and need to be protected from further contamination.
