Abstract

Long-term climate changes in humidity and soil wetness in the cold deserts of the Western Himalaya are still not well researched. Understanding the long-term trends of relative humidity (RH) and soil moisture is crucial in high-altitude, cold desert regions for effective agricultural management and environmental sustainability. The study was conducted in a part of the western Himalaya, which is an ecologically fragile zone with a highly sensitive agricultural region that is vulnerable to climatic variations. A comprehensive study was conducted to evaluate the spatiotemporal variability of RH and soil wetness by means four techniques: Mann-Kendall, Modified Mann-Kendall, Sen’s slope estimator, and innovative trend analysis. All this was done using NASA POWER climate data from 1981 to 2023. High RW and soil wetness levels were observed in all seasons, with a statistical significance obtained through the Z-values: 12.64 for RH and 9.91 for soil wetness. The monsoon and agricultural seasons were the most intense periods of development. The strongest upward trends were observed in the southern and central subregions. The slopes of Sen showed an annual rise of the RH of 0.31% per year and of the soil moisture of 0.0073 m³/m³/year. The results show significant changes in agriculture and its sustainability. The introduction of new disease-resistant and short-duration crop varieties, the implementation of precision irrigation based on real-time soil moisture data, and adoption of agro-climatic advisories tailored to seasonal fluctuations. However, combining these hydro-climatic patterns with regional climate-smart agriculture strategies, improving monitoring infrastructure, and reinforcing early warning and insurance systems are crucial methods for planning climate-resilient policies in cold desert agro-ecosystems.

Abstract

Sustainability practices are increasingly prominent in investor assessments of firm value Nevertheless, empirical evidence regarding which specific environmental practices are incorporated into capital market valuations remains inconclusive, particularly within mining sectors in emerging markets. This study investigates the correlation between sustainability practices energy efficiency, water management, waste management, renewable energy adoption and environmental quality (PROPER rating) together with operational efficiency and firm value in Indonesian listed mining firms. The analysis uses panel data for 23 firms over 2017–2023. Firm value is measured by Tobin’s Q, while operational efficiency is measured using Data Envelopment Analysis (DEA). The correlation is estimated using panel regression models. The results show that renewable energy adoption is the only sustainability practice which positively and significantly correlated with firm value (β=1.2026, p=0.0227). Firm size is also positively correlated with Tobin’s Q (β=0.4195, p<0.001). However, energy efficiency, water management, waste management, environmental quality (PROPER rating) and DEA based operational efficiency are not significantly correlated with firm value in the observed period. These findings indicate that capital markets place higher weight on strategic sustainability commitments, particularly energy transition than on incremental operational improvements. By disaggregating sustainability dimensions and incorporating efficiency measures, this study contributes to the literature on sustainability firm value correlates in resource-based industries within emerging markets. The results imply that while renewable energy investments may be more reflected in market valuation, other environmental and efficiency related practices may require longer time horizons or stronger disclosure mechanisms to be recognized by investors. Enhancing the credibility of sustainability reporting may therefore improve the alignment between firm performance and market perception.

Abstract

Certification mandates under the Roundtable on Sustainable Palm Oil (RSPO) and Indonesian Sustainable Palm Oil (ISPO) have made measurable strides in promoting sustainability standards, yet governance challenges in High Conservation Value (HCV) 4, 5, and 6 management remain insufficiently addressed within Indonesian plantation contexts.  Drawing on adaptive governance theory and the social-ecological systems framework, this study argues that such gaps are structurally linked to the marginalisation of community agency within corporate-dominated decision-making. This study proposes and empirically evaluates an integrated governance framework that positions community engagement as a functional contributor to conservation outcomes within plantation landscapes of West Kalimantan, under conditions where corporate decision-making currently dominates. A concurrent mixed-methods design was applied across three concessions, combining spatial analysis of HCV zones, Management Effectiveness Tracking Tool (METT) assessments across 30 indicators, structured questionnaires administered to 320 community informants, and Soft Systems Methodology (SSM) synthesis into a polycentric management model. Results indicate an overall METT score of 75.8%, revealing pronounced dimensional asymmetries: Output (100%) and Planning (85%) scores substantially exceeded Context and Input dimensions (66.7% each). This reflects the prioritisation of infrastructure over participatory mechanisms with median HCV budget allocations of 2.3% and only 8% community involvement in formal monitoring. A participatory deficit characterised all management phases, as 48% of respondents reported predetermined corporate decisions lacking dialogue, while 71% contested collaborative agreement processes. Despite these limitations, community engagement quality demonstrated a statistically significant positive association with METT performance (r=0.67, p<0.05). Microenterprise activities emerged as enabling conditions for conservation participation. These findings support reorienting HCV governance frameworks to treat community welfare as a primary enabling condition rather than an ancillary co-benefit. The SSM-integrated model establishes a 75% METT threshold as a trigger for adaptive management improvements, offering actionable pathways for reconciling commercial agriculture with biodiversity conservation.

Abstract

As smart cities increasingly rely on digital platforms to deliver public services, citizen participation becomes essential for ensuring effective and sustainable service delivery. However, limited research has examined which citizen-related factors drive co-creation behaviors in smart city contexts, particularly in emerging economies. This study aims to investigate the factors that influence the co-creation behaviors of online public services in five smart cities in Indonesia through the city’s digital platform and online social network (OSN). This study analyzes whether citizen factors, namely, perceived benefits over the city and OSN friends, trust in the city and OSN friends, and self-efficacy, affect co-creation behaviors leading to citizen satisfaction. A survey with 1009 respondents was conducted in Jakarta, Bandung, Semarang, Surabaya, and Denpasar, and the collected data were analyzed using covariancebased structural equation modelling. The results show that perceived benefit from OSN friends is the dominant factor that affects co-creation behaviors, which in turn affects citizen satisfaction. These findings highlight the critical role of OSN in fostering co-creation and suggest that integrating online public services with OSN can enhance service quality and citizen satisfaction.

Abstract

Although environmental noise has been extensively studied, limited research has compared the differential effects of natural and urban soundscapes on psychological outcomes. This pilot study examined the impact of urban and natural soundscapes on students’ concentration and affective responses. A pre–post experimental design with two groups was implemented, involving 12 undergraduate participants (aged 18–24 years) with equal gender representation. Concentration was measured using the polyshape board, which was preliminary validated in this study, while affective states (pleasantness and arousal) were assessed using the Affect Grid Scale (AGS) before and after exposure. Given the limited sample size and the ordinal data, the Wilcoxon Signed-Rank test was applied. The analysis revealed a significant difference in concentration between the two conditions (p=0.037), with higher and more stable scores observed under natural sound exposure (M=32.9; Md=35.5) compared to urban sound conditions (M=31.1; Md=34.5). Manipulation checks indicated no significant difference in pleasantness (p=0.224), while arousal differed significanly between conditions (p=0.045), with higher arousal reported in the urban sound conditions. These findings suggest that natural sounds may be associated with improved concentration and reduced arousal in controlled educational and laboratory settings. However, given the small sample size and short exposure duration, the findings should be considered preliminary and require further investigation with higher and more diverse samples.

Abstract

Environmental pollution from hydrocarbons and their derivatives is predominantly of anthropogenic origin, occurring mainly during mining, transportation, and storage. This often in an annual release of substantial amounts of pollutants into the environment. The effective restoration of petroleum-contaminated environments requires a series of interventions to remediate soil to its natural state. This study aimed to isolate and characterize biosurfactant-producing bacterial strains with potential bioremediation capabilities to assess the potential application for remediating soils polluted with spent engine oil in the Remo district, Ogun State. Bacterial isolates were recovered from soil samples collected from spent engine oil contaminated sites, using standard cultural techniques and characterized by biochemical and molecular techniques (16S rRNA amplification and sequencing). The isolates were further screened for biosurfactant activity, and the biosurfactant extract was characterized using gas chromatography-mass spectrometry (GC-MS) and Fourier-transform infrared (FTIR) spectroscopy. All 36 isolates recovered from the samples were positive for blood hemolysis, oil spread, and emulsification index assays. Pseudomonas sp. and Klebsiella sp. were identified as the most promising biosurfactant-producing isolates by 16S rRNA gene sequencing by the screening results. The GC-MS and FTIR spectroscopy of the biosurfactant extracts produced by Pseudomonas sp. revealed distinct peak values with various functional groups. FTIR analysis identified various functional groups, including aliphatic ether, ester, sulfone, alkene, allene, isothiocyanate, and alcohol, as the major compounds present in the biosurfactant. 20 bioactive compounds with different peak values were identified by GC-MS analysis. The rhlA gene associated with rhamnolipid production was detected in the two characterized P. aeruginosa strains. Subsequent laboratory-scale bioremediation of spent engine oil-contaminated soil demonstrated a significant (53%) removal of oil. The results highlight the potential applicability of eco-friendly biosurfactants for contaminated soil cleanup and suggest the need for further exploration, optimization, and elucidation of the genetic basis of biosurfactant production for improved efficacy.

Abstract

Younger generations have begun to change their purchasing behaviour in response to growing environmental concerns and global sustainability efforts. This research evaluates the eco-friendly shopping habits of Zoomers (born 1997–2012) and Millennials (born 1981–1996) in India. The research employs the Theory of Planned Behaviour (TPB) to analyse how the stewardship model, subjective norms, perceived consumer effectiveness, environmental attitudes and ecological values influence green product buying behaviour. A quantitative research design was adopted, and data were collected from 391 respondents across urban, semi-urban, and rural regions using a structured questionnaire. The relationship between the constructs were examined using structural equation modelling (SEM). The results indicate that environmental awareness (β = 0.558) has a strong positive influence on green purchasing behaviour, followed by social influence (β = 0.225). Environmental awareness is significantly driven by attitude towards the environment (β = 0.430) and ecological values (β = 0.356). Social influence is primarily driven by subjective norms (β = 0.338) and perceived consumer effectiveness (β = 0.187), whereas stewardship orientation has a negligible effect (β = 0.025). The model explains 50.7% of the variance in green purchasing behaviour (R² = 0.507), 51.1% in environmental awareness (R² = 0.511), and 28.4% in social influence (R² = 0.284).  The findings confirm the presence of an attitude–behaviour gap, where positive environmental attitudes do not consistently translate into actual purchasing behaviour because of various influences such as price sensitivity and the non-existence of sustainable products. This study contributes to the literature by extending TPB through the inclusion of ecological and social mediators and by providing comparative insights into generational differences in an emerging market context. The results provide useful implications for marketers and policymakers to create focused strategies that encourage sustainable consumption.
