The Role Of Traditional Rulers In Curbing Farmer Herder Conflict In Ukum Local Government Area Of Benue State, 2011-2023

This study interrogates the role of traditional rulers in the management of farmer herder conflict in Ukum Local Government Area of Benue state, 2011-2023 with the aim of unfolding the persistent incursion on the farming communities of Ukum LGA by the herders and the task of traditional rulers in managing it. Using Eco violence theory the study explained the inextricable link between the environment and violent conflicts between the herders and farmers n Ukum LGA. The study used the descriptive survey design. Qualitative method of data collection was adopted and the instruments for data collection were key informant interview and focus group discussion. The secondary data were gathered from text books, and journals. The method of data analysis was the explorative as the data were descriptions, accounts and experiences or feelings of the respondents. The study found that the nature of farmer herder crisis is the conflict between the economic activities of human beings for survival and the effect of the survival on the ecosystem.. the effect is the intolerable experience the indigenes are passing through as the idle youths have turned the conflict as a means of livelihood. Though the traditional rulers have been trying to curb the situation, there are challenges that are rooted in politics. The study concludes that government must be careful in selecting the traditional rulers and give them a free hand in managing the affairs of their communities. The study recommends majorly that Government must embrace the modern system of livestock farming to reduce competition over scarce environmental resources

Preserving environmental quality of ecotourism sites through community participation in Purulia District of West Bengal, India

The importance of valuing environmental resources, especially in ecotourism sites, has become increasingly important over the last two decades. Ecotourism is now considered as an important source of livelihood of local stakeholders in backward regions. Therefore, the preservation of ecotourism sites through community participation seems very important to maintain continued flow of tourists. This study aimed at recognizing the importance of community participation for the preservation of ecotourism sites. For this, this study executed a survey based on non-probability sampling in two ecotourism sites (Garpanchkot and Baranti) covering 100 respondents in Purulia District, West Bengal of India. The central issue of this study was to assess the tendency of community participation for the conservation of ecotourism sites and find the optimum condition for offering participatory labour time. This study showed that the participation of young people is high, and the majority of respondents are aware of the importance in protecting ecotourism sites. Because respondents were too poor to offer money, the contingent valuation method (CVM) was used to elicit their willingness to pay (WTP) participatory labour time for the conservation of ecotourism sites. Respondents’ age, income, education level, caste, and their perceived environmental quality had significant relationship with their WTP participatory labour time by applying the ordinary least square (OLS) model. It was found that the mean WTP participatory labour time of each respondent in a month is approximately 3.64 h. The significance of this study is that community participation can improve the sense of belonging, trust, and credibility of ecotourism sites, making them more appreciative of the value and protection of these sites.

Participation of Business Actors in Implementing Circular Economy on Batik Products in Kauman Batik Kampoeng, Pekalongan City

This research explores the application and potential of batik business actors in the implications of the circular economy (CE) model in Pekalongan, Indonesia. As a prominent cultural heritage, the batik industry is essential to the regional economy. However, conventional linear production and consumption practices have resulted in environmental challenges, resource depletion, and waste generation. By embracing CE principles that emphasize resource efficiency, waste reduction, and closed-loop systems, the batik industry in Pekalongan can develop sustainable and environmentally responsible practices. This study examines critical aspects of CE implementation, starting with community participation in the batik, drawing insights from successful CE implementation in other industries. The implementation of CE in other industries is the role of business actors in the business chain outside Kampong. This paper analyzes the potential benefits and challenges of implementing CE in the Pekalongan batik industry and the role of stakeholders in promoting circularity. By highlighting the feasibility of the CE model, the results of this research are that the level of community participation in implementing a CE has not been maximized with the potential remaining production output so that this aspect of the condition becomes a sustainable opportunity to encourage sustainable practices in the Pekalongan batik industry.

Climate Variability and the Resilience of Smallholder Tea Production in the East Usambara Mountain Farming System, Tanzania

The complexities of climate change are well-known, and it has immediate and long-term consequences on the environment and natural resources. This global concern adversely affects sustainable development sectors and economic systems including the agricultural sector. The tea sector is among the largest export crops contributing to earnings and revenues. Its production has been declining, and the reasons behind this decline remain unclear. This study proposed to explore the influences of climate variability on the current productivity trend of smallholder tea farmers in Tanzania. The study involves quantitative data analysis, collected from 1990 to 2020 including monthly precipitation, temperature statistics, and Greenleaf production gathered as secondary data from the Tea Research Institute of Tanzania and the Tea Board of Tanzania. The study found that rainfall and temperature change significantly influence smallholder farmers' tea production in the East Usambara Mountains. The optimal climate elements (temperature and precipitation) positively improve smallholder farmers' tea production. In contrast, extreme climate variability triggers negative effects on tea production when precautions and adaptation measures are not considered. To summarize, it is recommended that farmers engage in different programs and training sessions to enhance their perception and adaptability to climate change.

Adoption of region-specific diets in China can help achieve gains in health and environmental sustainability.

The vast heterogeneity in dietary practices across China has led to profound regional disparities in health and environment. To address this issue, we developed a region-specific reference diet (RRD) that is better aligned with Chinese culinary traditions, affordable, sparing of natural and environmental resources, and contributes to health. The adoption of the RRD has proven to be a viable solution to facilitate a rapid transition towards a healthy and environmentally sustainable diet across the country when compared to dietary guidelines from the World Health Organization, the EAT-Lancet Commission and the Chinese Nutrition Society. The RRD improved health in all regions and resulted in reductions of all five environmental impacts measured. Given China's huge population and its major impact on global sustainability, the widespread adoption of the RRD would not only yield substantial health benefits domestically, but also contribute significantly to global food security and sustainability efforts.

Urban recreational green spaces dynamics and implications in the Bonaberi Neighbourhood of Douala IV Municipality, Cameroon

Globally, urban recreational green spaces constitute a major environmental resource of urban landscapes. These greeneries are suffering from shrinkages and transformations due to pressures on more urban land needed for housing, commercial and industrial purposes and uncontrolled urbanization. This study was conducted to assess the spatiotemporal variations and extent of transformations within the urban green spaces and their associated implications in the Bonaberi neighbourhood of Douala IV Municipality. To achieve this, empirical data was collected through field visits, in-depth interviews with urban authorities and mapping of urban green spaces for 2003 and 2022. Two hundred inhabitants were purposively sampled while local council authorities and other stakeholders were interviewed in the Douala IV Municipality. This was complemented by secondary data obtained from the Douala Urban Council. The collected data were analyzed using descriptive and inferential statistical techniques and results revealed that the rapid transformation and decrease of urban green spaces in terms of spatiotemporal nature is a function of expansion and uncontrolled urban settlements. The shrinkage in urban green spaces in the Douala IV municipality has resulted in loss of biodiversity, increase in urban heat islands, atmospheric pollution, unattractiveness of the environment, crimes, mental and physical health issues. This was x-rayed by the poorly arranged green spaces, littered with wastes and having multiple paths used by motorists, pedestrians and vendor activities. This study concludes that greeneries remain a vital environmental resource, thus, recommending effective application of planning policies to restrict their encroachment. Additionally, greeneries should be treated among the top priorities of the development agenda of urban planning authorities as enshrined in the Sustainable Development Goal 11.

Riparian forests shape trophic interactions in detrital stream food webs

Abstract Freshwater and terrestrial biodiversity are linked through spatial resource flows. Key examples are detrital subsidies from the riparian vegetation that form the base of food webs in small streams. Despite the central role of detritivores in these food webs, the consequences of altered riparian vegetation type and resource availability on their trophic strategies are less known. Therefore, we experimentally tested direct and indirect effects of riparian vegetation type (i.e. riparian forests present vs. absent) on trophic interactions and dietary imbalances of aquatic detritivores. To characterise trophic strategies, we used stoichiometric and isotopic differences between consumers and resources as functional measures of trophic link strength in leaf litter bags naturally colonised by stream decomposers and detritivores. Our results show that an absence of riparian forests affected stoichiometric and isotopic properties in stream detrital food webs. Where local riparian forests were absent, leaf litter showed lower C:N ratios, which only trichopteran detritivores mirrored, whereas plecopteran and crustacean detritivores showed differences in their isotopic signatures. Diverging patterns between resources and consumers could lead to a rewiring of energy flow paths and weaken the coupling between aquatic detritivores and terrestrial detritus. Consequently, our findings demonstrate that riparian forests are essential for aquatic food webs by not only influencing organisms themselves but also their trophic interactions and energy flow paths. Aquatic detritivores depending on terrestrial subsidies can be highly sensitive to local changes in their resource environment. Therefore, functionally divergent patterns between resources and consumers in recipient systems highlight how habitat properties of the donor system can affect food webs connected across ecosystem boundaries.

Application of gradient boosting machine in satellite-derived bathymetry using Sentinel-2 data for accurate water depth estimation in coastal environments

Accurate water depth estimation is crucial in coastal environmental management, resource exploration, and ecological protection. Traditional water depth measurement methods are often time-consuming and costly, especially in vast sea areas where their application is limited. However, with the rapid development of remote sensing technology, particularly the widespread use of high-resolution satellite imagery, water depth remote sensing has emerged as a more efficient, economical, and widely applicable solution. In this study, we utilized Sentinel-2 satellite data and applied various algorithms to accurately estimate water depth in the Nanshan Port area. The results showed that the Gradient Boosting Machine (GBM) model excelled in monitoring shallow water and coastal environments, effectively addressing challenges such as light attenuation and water scattering in turbid waters. Compared to traditional methods, GBM-generated predictions were smoother and more detailed. This study not only demonstrates the significant potential of satellite remote sensing for water depth measurement but also points to future directions for algorithm optimization and the integration of remote sensing technologies. It is expected to bring revolutionary progress to oceanic scientific research and coastal management.

Utilizing machine learning techniques for enhanced water quality monitoring

ABSTRACT Water quality is an important issue for environmental health. It directly impacts human well-being, ecosystem sustainability and socioeconomic development. This paper provides an overview for water quality assesment by integrating traditional methods with computational technology. Dimensionality reduction is considered an essential preprocessing step in any data analysis task which can be performed by using either feature selection or feature extraction methods. In this study, we propose an autoencoder-based feature selection method that can be used with both labeled and unlabeled data. It can be implemented with an arbitrary number of hidden layers in the symmetric encoder part of the autoencoder and provides results that compare favorably with the results provided by computationally more expensive methods and also provides a quantitatively ordered rank of features for the features in the dataset. Also, our proposed method for water quality assessment has demonstrated remarkable success in efficiently managing and interpreting complex datasets, offering a promising pathway toward effective environmental stewardship and sustainable water resource management. Through its implementation, we aim to contribute to the preservation and protection of water quality for the benefit of present and future generations.

Research on Application of Composite Facades for Civilian Reconstruction of Industrial Heritage in Cold Regions Based on Thermal Buffering Effect

Previous studies on the civil transformation of industrial heritage have been conducted mainly from the perspective of architectural history, culture and aesthetics, but rarely focus on energy-saving and the comfort of the new users. Most industrial heritage facades are of high conservation value, but efforts to preserve the authenticity of the facade can lead to the application of limited energy-saving technologies, ultimately resulting in poor indoor thermal environments. Therefore, it is valuable to research how to solve the contradiction between protecting the authenticity of the preserved facades of industrial heritage and improving the indoor environmental performance. This paper proposes two composite facade application strategies based on thermal buffer effects, takes two composite facades renovation methods of Shenyang Dongmao No. 2 Warehouse as an example, utilizes the natural environmental resources to enhance the spatial quality of industrial heritage. With the help of DesignBuilder software modelling simulation analysis, in-depth comparative analysis of the two types of composite facades on the indoor thermal environment of the industrial heritage of the impact and scope. Key findings show that the application of two different composite facade retrofitting techniques not only protects the skin texture of the wall, but also effectively increases the indoor temperature and reduces the indoor energy consumption of the industrial heritage. The composite facade of the external solid wall and the internal glass is more stable in raising the indoor temperature, more effective in reducing the building energy consumption, and more suitable for the civilian transformation of industrial heritage in cold areas. The research findings provide reference for studies on the civil transformation of industrial heritage, and serve as technical references for architects.

Optimizing Response Rates to Examine Health IT Maturity and Nurse Practitioner Care Environments in US Nursing Homes: Mixed Mode Survey Recruitment Protocol.

Survey-driven research is a reliable method for large-scale data collection. Investigators incorporating mixed-mode survey designs report benefits for survey research including greater engagement, improved survey access, and higher response rate. Mix-mode survey designs combine 2 or more modes for data collection including web, phone, face-to-face, and mail. Types of mixed-mode survey designs include simultaneous (ie, concurrent), sequential, delayed concurrent, and adaptive. This paper describes a research protocol using mixed-mode survey designs to explore health IT (HIT) maturity and care environments reported by administrators and nurse practitioners (NPs), respectively, in US nursing homes (NHs). The aim of this study is to describe a research protocol using mixed-mode survey designs in research using 2 survey tools to explore HIT maturity and NP care environments in US NHs. We are conducting a national survey of 1400 NH administrators and NPs. Two data sets (ie, Care Compare and IQVIA) were used to identify eligible facilities at random. The protocol incorporates 2 surveys to explore how HIT maturity (survey 1 collected by administrators) impacts care environments where NPs work (survey 2 collected by NPs). Higher HIT maturity collected by administrators indicates greater IT capabilities, use, and integration in resident care, clinical support, and administrative activities. The NP care environment survey measures relationships, independent practice, resource availability, and visibility. The research team conducted 3 iterative focus groups, including 14 clinicians (NP and NH experts) and recruiters from 2 national survey teams experienced with these populations to achieve consensus on which mixed-mode designs to use. During focus groups we identified the pros and cons of using mixed-mode designs in these settings. We determined that 2 mixed-mode designs with regular follow-up calls (Delayed Concurrent Mode and Sequential Mode) is effective for recruiting NH administrators while a concurrent mixed-mode design is best to recruit NPs. Participant recruitment for the project began in June 2023. As of April 22, 2024, a total of 98 HIT maturity surveys and 81 NP surveys have been returned. Recruitment of NH administrators and NPs is anticipated through July 2025. About 71% of the HIT maturity surveys have been submitted using the electronic link and 23% were submitted after a QR code was sent to the administrator. Approximately 95% of the NP surveys were returned with electronic survey links. Pros of mixed-mode designs for NH research identified by the team were that delayed concurrent, concurrent, and sequential mixed-mode methods of delivering surveys to potential participants save on recruitment time compared to single mode delivery methods. One disadvantage of single-mode strategies is decreased versatility and adaptability to different organizational capabilities (eg, access to email and firewalls), which could reduce response rates.

Maternal risk-management elucidates the evolution of reproductive adaptations in sharks by means of natural selection

Maternal investment theory is the study of how breeding females allocate resources between offspring size and brood size to achieve reproductive success. In classical trade-off models, r/K-selection and bet-hedging selection, the primary predictors of maternal investments in offspring are population density and resource stability. In crowded, stable environments, K-selected females invest in large offspring at an equivalent cost in brood size. In uncrowded, unstable environments, r-selected females invest in large broods at an equivalent cost in offspring size. In unpredictable resource environments, bet-hedging females invest moderately in brood size and offspring size. The maternal risk-management model represents a profound departure from classical trade-off models. Maternal investments in offspring size, brood size, and brood number are shaped independently by autonomous risk factors: the duration of gaps in resources during seasonal cycles, rates of predation, and unpredictable catastrophic events. To date, no single model has risen to a position of preeminence. Here in sharks, we show that maternal investments within and across species do not agree with the predictions of trade-off models and instead agree with the predictions of the maternal risk-management model. Within and across shark species, offspring size and brood size were independent maternal investment strategies. The risk of starvation favored investments in larger offspring. The risk of predation favored investments in larger broods. If empirical studies continue to confirm its predictions, maternal-risk management may yet emerge as a unifying model of diverse reproductive adaptations by means of natural selection.

I Was the Violence Victim, I Am the Perpetrator: Bullying and Cyberbullying Perpetration and Associated Factors among Adolescents

Bullying and cyberbullying significantly threaten the development and mental health of both victims and perpetrators. This study aimed to analyze the associations between socioeconomic characteristics, personal experiences of violence, perceived social support from peers, and acceptance of violence and (cyber)bullying perpetration. The study involved 1146 secondary school students, consisting of 698 females and 448 males, aged 13 to 16. Prevalence ratios (PRs) were calculated using Poisson regression with robust variance. The results indicated that 12.32% of girls and 18.97% of boys reported engaging in bullying and/or cyberbullying. The likelihood of perpetration was lower among adolescents who had not experienced physical and/or sexual abuse before age 15, but higher among those in romantic relationships who had been victims of dating violence or had experienced (cyber)bullying victimization. Additionally, perceived social support from classmates was associated with a lower likelihood of becoming a perpetrator, whereas acceptance of violence was positively associated with (cyber)bullying perpetration. Preventing adolescents from becoming perpetrators of bullying and/or cyberbullying requires early intervention to prevent all forms of violence in childhood and adolescence, as well as bolstering personal and environmental resources by providing social support.

Origin of biogeographically distinct ecotypes during laboratory evolution

Resource partitioning is central to the incredible productivity of microbial communities, including gigatons in annual methane emissions through syntrophic interactions. Previous work revealed how a sulfate reducer (Desulfovibrio vulgaris, Dv) and a methanogen (Methanococcus maripaludis, Mm) underwent evolutionary diversification in a planktonic context, improving stability, cooperativity, and productivity within 300–1000 generations. Here, we show that mutations in just 15 Dv and 7 Mm genes within a minimal assemblage of this evolved community gave rise to co-existing ecotypes that were spatially enriched within a few days of culturing in a fluidized bed reactor. The spatially segregated communities partitioned resources in the simulated subsurface environment, with greater lactate utilization by attached Dv but partial utilization of resulting H2 by low affinity hydrogenases of Mm in the same phase. The unutilized H2 was scavenged by high affinity hydrogenases of planktonic Mm, producing copious amounts of methane. Our findings show how a few mutations can drive resource partitioning amongst niche-differentiated ecotypes, whose interplay synergistically improves productivity of the entire mutualistic community.

Do Firms Follow through on Environmental Commitments? An Empirical Examination

In response to ever-increasing pressure from stakeholders to reduce the impact of their operations and supply chain on the natural environment, firms frequently make public commitments to improve environmental performance. However, the commitments are difficult to validate and thus of unknown quality. Understanding whether and when the commitments are valid proxies for action is essential because they are used by environmentally conscious stakeholders to assess firm environmental performance in anticipation of buying from, investing in, working for, or selling to a firm. Results from examining 442 U.S. manufacturing firms show that firms generally follow through on such commitments. Larger firms and firms with better environmental performance are more likely to follow through. However, firms tend not to follow through if they are experiencing negative environmental publicity or resource constraints at the time of the commitment. The results provide important insights for environmentally conscious stakeholders who use the commitments to determine whether to buy from, invest in, work for, or supply to a firm. The study also highlights the benefits to firm leaders of following through and provides input towards ideas that can increase follow-through. Finally, the study contributes to several streams of the research literature, including the literature evaluating environmental management, environment commitments, and environmental accidents.

Mandatory environmental disclosure policy in the largest carbon emission country

Purpose This paper aims to examine the impact of corporate environmental transparency (CET) on corporate financial performance under a mandatory environmental disclosure policy in China, the largest carbon-emitting country. It aims to clarify the concept of CET and investigate its short-term financial implications for key pollutant-discharging entities (KPEs). Design/methodology/approach A multidimensional model is used to construct a comprehensive CET index for KPEs in China. Empirical tests are conducted to assess the relationship between CET and corporate financial performance. Findings The study finds a negative relationship between CET and corporate financial performance in the short term. Increased environmental transparency necessitates higher environmental resource allocation, adversely affecting profits. The results remain unchanged from a battery of robustness tests. Despite mandatory disclosure, companies tend to provide general and vague information rather than specific and meaningful environmental data. Research limitations/implications The findings provide rich practical implications for policymakers to improve a mandatory environmental disclosure policy. The paper also contributes to the existing knowledge by developing a measure of CET and presenting new evidence to the debate on whether corporate environmental disclosure can be regarded as transparency. Practical implications Policymakers are advised to refine mandatory environmental disclosure regulations to ensure genuine transparency and to implement policy measures that alleviate the financial burdens of companies with high CET levels, thereby encouraging sustainable practices. Originality/value This paper contributes to the existing knowledge by developing a measure of CET and providing new evidence on the debate over whether environmental, social and governance (ESG) disclosure equates to transparency. It emphasizes the complexity of transparency and the inadequacy of current environmental disclosure practices among KPEs. The study underscores the need for financial support for companies with high CET levels to alleviate short-term financial strains and promote long-term sustainability.

Rainfall analysis in Xingu River Basin based on the 1981-2020 timeframe

It is essential understanding the incidence of hydrometeorological variables in each river basin to help planning actions focused on guaranteeing multiple water uses, environmental preservation and prevention measures taken against extreme events. The aim of the current study is to investigate rainfall trends in Xingu River Hydrographic Basin (XRHB) from 1981 to 2020. Data propensity analysis was carried out based on the Mann-Kendall methods, on five-year moving average graph, as well as on variations in Climatological Normals (CN) recorded from 1981 to 2010 and from 1991 to 2020. Moreover, the Log-Normal theoretical distribution was adjusted to show mean rainfall predictions within 10-to-100-year return time (Rt). It was done by applying the Kolmogorov-Smirnov (KS), Chi-Square (?2), Filliben (Fi) and Anderson-Darling (AD) tests. Results have evidenced historical series with no trend and minimal variation (-0.5%) between the two CN intervals. Estimates within a 10-to-100-year RT scenario have evidenced rainfall rates higher than the historical average (HA) ranging from 10.0% to 20.0%. Thus, XRHB is a promising scenario for water security planning purposes, since it meets the fundamentals of Brazilian environmental and water resources laws, as well as target 6.5 of Sustainable Development Goal 6 (SDG 6 - UN), which deals with implementing integrated water-resources management at global level.

Recent Advances in Natural-Polymer-Based Hydrogels for Body Movement and Biomedical Monitoring.

In recent years, the interest in medical monitoring for human health has been rapidly increasing due to widespread concern. Hydrogels are widely used in medical monitoring and other fields due to their excellent mechanical properties, electrical conductivity and adhesion. However, some of the non-degradable materials in hydrogels may cause some environmental damage and resource waste. Therefore, organic renewable natural polymers with excellent properties of biocompatibility, biodegradability, low cost and non-toxicity are expected to serve as an alternative to those non-degradable materials, and also provide a broad application prospect for the development of natural-polymer-based hydrogels as flexible electronic devices. This paper reviews the progress of research on many different types of natural-polymer-based hydrogels such as proteins and polysaccharides. The applications of natural-polymer-based hydrogels in body movement detection and biomedical monitoring are then discussed. Finally, the present challenges and future prospects of natural polymer-based hydrogels are summarized.
