Invasion by non-native tree species is an environmental and societal challenge requiring predictive tools to assess invasion dynamics. The frequent scale mismatch between such tools and on-ground conservation is currently limiting invasion management. This study aimed to reduce these scale mismatches, assess the success of non-native tree invasion and determine the environmental factors associated to it. A hierarchical scaling approach combining species distribution models (SDMs) and satellite mapping at very high resolution (VHR) was developed to assess invasion by Acacia dealbata in Peneda-Gerês National Park, the only national park in Portugal. SDMs were first used to predict the climatically suitable areas for A. dealdata and satellite mapping with the random-forests classifier was then applied to WorldView-2 very-high resolution imagery to determine whether A. dealdata had actually colonized the predicted areas (invasion success). Environmental attributes (topographic, disturbance and canopy-related) differing between invaded and non-invaded vegetated areas were then analyzed. The SDM results indicated that most (67%) of the study area was climatically suitable for A. dealbata invasion. The onset of invasion was documented to 1905 and satellite mapping highlighted that 12.6% of study area was colonized. However, this species had only colonized 62.5% of the maximum potential range, although was registered within 55.6% of grid cells that were considerable unsuitable. Across these areas, the specific success rate of invasion was mostly below 40%, indicating that A. dealbata invasion was not dominant and effective management may still be possible. Environmental attributes related to topography (slope), canopy (normalized difference vegetation index (ndvi), land surface albedo) and disturbance (historical burnt area) differed between invaded and non-invaded vegetated area, suggesting that landscape attributes may alter at specific locations with Acacia invasion. Fine-scale spatial-explicit estimation of invasion success combining SDM predictions with VHR invasion mapping allowed the scale mismatch between predictions of invasion dynamics and on-ground conservation decision making for invasion management to be reduced. Locations with greater potential to suppress invasions could also be defined. Uncertainty in the invasion mapping needs to be accounted for in the interpretation of the results.

PurposeThe study aims to provide important insights into environmental attributes that are relevant to consumer's choices in purchasing canned tuna fish, and how much these attributes and socio-demographic individual characteristics relate to the frequency of consumption.Design/methodology/approachAn online survey of 251 Italians was carried out. Socio-demographic variables and environmental attributes of the product that consumers pay attention to were considered in a two-step analysis: a cluster analysis used to create a segmentation of people's profiles that are further characterised; a binary logistic regression to assess the significance of attributes in relation to the frequency of canned tuna consumption.FindingsAmong attributes that respondents pay attention to when purchasing canned tuna, the country of origin is the aspect most considered, while other characteristics with a higher content of environmental sustainability received minimal attention. Three clusters emerged: the smallest one, insensitive to sustainability issues; an intermediate group which is mindful of sustainability attributes; and the biggest cluster which is “sustainability inconsistent.” Moreover, respondents who reported concerns about the environmental impacts of tuna production are less likely to consume the product than other consumers; attention paid to the method of farming, the presence of children and a young age show willingness to consume tuna.Originality/valueThis study contributes to the literature on canned tuna consumption by focusing on the attention that consumers pay to environmental product attributes in their purchasing choices. The relevance of this topic might be envisaged in relation to several environmental issues associated with tuna production and consumption, and to the economics and strategies of the tuna industry, being canned tuna among the most internationally traded seafood products.

In Malaysia, the population of older adults will increase in the coming years. In this context, there is a requirement to build an age-friendly environment to enable the elderly to age healthily. Many studies have shown that a built environment that allows older adults to age in place improves their mental health. However, person-environment analysis that considers mental well-being has remained rare for older adults living in Malaysia. This study examines the relationship between Malaysian seniors’ perceptions of their surroundings at home and in the neighborhood and their mental health. Using stratified sampling, 510 seniors aged 60 and over were interviewed. The results showed that accessibility (p-value 0.033, 95% CI for coefficients 0.006, 0.146), environmental qualities (0.015, 0.014, 0.129) and neighborhood problems (0.000, −0.299, −0.146) were significant determinants of elderly people’s mental health. With respect to respondents’ socio-demographic characteristics, female elderly (0.000, 0.616, 0.782), older adults with an elementary education (0.000, 0.263, 0.685) or a college degree (0.026, 0.019, 0.294), being married (0.005, 0.047, 0.259), the ability to drive (0.000, 0.993, 1.315), the number of dependents in the family (0.003, −0.060, −0.012), and homeownership (0.000, −0.602, −0.271) were significantly related to mental well-being.

The present research underlines the need to expand far outside bundling or hierarchical providing strategy that often focuses on a specific habitat or ecosystem and creates a location-based strategy that considers how dependency in other parts of the region with ecosystem functions and processes leads to complements and resources’ trade-offs. Thus, for assessment of spatial heterogeneity based on willingness to pay (WTP) for upgrading environmental attributes across Heihe River Basin (HRB), a choice experiment survey was carried out in the entire river basin. The HRB is one of the big inland river in the Northwestern region of China and is selected on basis of its geomorphological and geographical significance. A sum of 1679 individuals were interviewed through choice experiment technique from whole river basin consisting of five main cities and 33 adjoining rural areas. The Random Parameter logit model, Krinsky-Robb technique as well as delta method were applied for the evaluation of spatial heterogeneity and estimation of individual specific WTP, respectively. Spatial heterogeneity is verified among sampled individuals’ preferences about upgradation of environmental attributes, such as, observed preferences of individuals’ and their varying corresponding WTP amounts for per unit’s upgradation in agriculture product quality, greenhouse gases reduction, farmland landscape, and biodiversity, which reflects heterogeneous tastes and preferences of the selected individuals. In addition, the assessed outcomes for identifying the impacts of distance decay through random parameter logit model depicted the vital role of distance influence on respondents’ WTP for restoring the degraded environmental attributes, such that among 3 ad hoc distance bands, WTP of those sampled individuals who are in proximity of ≤ 10 km to HRB is more than the rest of the individuals, i.e., individuals living in the range of ≤ 20 km and > 20 km. For instance, WTP for agriculture product quality is 119.147 CNY/year in ≤ 10 km and is higher than the remainders. Graphical abstract

Purpose The purpose of this paper is to investigate the activities of environmental consciousness from socio-psychographic perspectives and hence evaluates its effect on brand equity through intervening elements of environmental attributes (EAt). It further attempts to research the effect of the environmental performance, environmental communication and environmental positioning in enhancing brand equity. Indian refrigeration industry, particularly the air conditioners and refrigerator brands are chosen to convey and receive the research inputs as their impact on environment is easily interpretable. Design/methodology/approach A hypothesized model comprising the environment consciousness and association dimensions with brand equity is framed. In total, 74 expert respondents from four state capital cities of India participated in the survey and the model has been tested in the scope of analytical hierarchy process (AHP). Findings The result shows that the EAt and activities can be prioritized and subsequently efficient resource allocation can be done. It also gives theoretical arguments to legitimize the environmental practices. Practical implications On the other hand, clients have numerous options, and a competitive advantage may not be maintained. Regardless of the fact that clients are environmentally conscious of a given refrigeration brand at the present time that they are utilizing, they may observe that they are much more charmed with a competitors' enhanced environmental dimensions. All methods that take a try at an enhanced brand equity must be continually determined by environmental consciousness. The above can be accomplished if the evaluations of competitors by the clients are known. The AHP-ECBE technique depicted in this study accordingly helps refrigeration organization to devise and keep up a pertinent, focused plan for persistent improvements in environmental dimensions. It offers a \"greater image\" in brand equity administration. Originality/value If legitimately done in a generalized way, environmental activities like eco-literacy, interpersonal influence and value orientation can impact EAt and contribute in building brand equity.

Urban flood risk assessments play a crucial role in urban resilience and disaster management. This paper proposes a comprehensive method for urban flood risk assessment and prediction that is based on environmental attributes and the operational characteristics of pipe networks. Using the central urban area of Zhengzhou as a case study, an integrated urban flood risk evaluation index system was developed, and the entropy weight method was applied to quantify risk indicators. A loosely coupled RF-XGBoost model was constructed to predict the flood risk of different rainfall scenarios. The results indicate that (1) the overall flood risk in the study area exhibits an increasing trend from the northeast to the southwest, with medium- to high-risk zones being predominant; (2) the spatial distribution pattern of the comprehensive flood risk closely aligns with that of the environmental risk but shows slight variations under the influence of pipe network operational risks; (3) the RF-XGBoost model demonstrates superior predictive accuracy under multi-factor coupling scenarios. When rainfall characteristics, environmental attributes, and pipe network operational risks are comprehensively considered, the Nash–Sutcliffe Efficiency (NSE) of the predictions improves from 0.85 (when using only rainfall characteristics) to 0.94. This study provides valuable insights and technical support for mitigating urban flood risks.

Promoting park vitality is fundamental for advancing both residents’ well-being and sustainable urban development. Current research often sidesteps the temporal fluctuations and combined effects of environmental factors on park vitality. Drawing on real-time user density data from Tencent, this investigation analyzed park vitality across 64 urban parks in Fuzhou, China, divided into five specific temporal periods on weekdays and weekends. Through the application of geographic detector models, this study examined the impact and interplay of both intrinsic and extrinsic environmental characteristics on park vitality over these different times. Our primary findings include: (1) environmental attributes affecting park vitality vary temporally, with aspects like commercial density, leisure facility density, and park size consistently influencing vitality; (2) on weekdays, external attributes linked to convenience are predominant, while on weekends, internal attributes connected to recreation take precedence; and (3) there is a synergetic interaction between environmental determinants, often leading to either additive or more intricate effects on park vitality. Based on these insights, we propose recommendations for spatial planning and time-based policies to enhance the alignment between urban settings and park quality. This research provides actionable strategies for enhancing park vitality, both within China and internationally.

This study analyzed the trends and changes in climate-sensitive plants based on environmental attributes, using on-site survey data collected between 2006 and 2018. In combination with environmental attributes, 16 plant species were chosen as climate-sensitive biological indicator species and were spatially distributed based on national ecological survey data. With the use of regression methods and locally weighted scatterplot smoothing, possible changes in the vegetation distribution trends were simulated. The findings indicated that annual rainfall and temperature are critical environmental attributes, as they mostly affect the plant ecosystem. The simulated results suggest that plant habitats for the selected 16 individual species tend to be found in higher temperature zones, with a few exceptions. However, there was no clear pattern of the effects of annual rainfall on climate-sensitive plant species. The effects of climate change on these species are a risk to the environment; however, depending on the situation, adequate adaptation and management plans could provide opportunities for policy makers to make evidence-based decisions.

There is a growing demand for industrial materials that claim environmental attributes based on life cycle thinking. To track and manage such environmental attributes, Chain of custody (CoC) models are growingly applied. Among CoC models, the mass balance model–credit method (MB-CR) and book and claim (B&C) model implement non-proportional allocation of environmental attributes. Though there is a case that applying these models could avoid additional environmental burdens that would otherwise occur, the eligibility of applying non-proportional allocation requires careful consideration. This study aims to clarify the requirement and limitation for applying MB-CR and B&C models and to justify the cases of applying those models. A key requirement is environmental rationality, defined as the ability to contribute to avoiding additional environmental burdens, particularly during transition phases where the target environmental attribute is not abundant. A key limitation is technical feasibility, which constrains allocation within what is physically achievable for industrial materials. This study contributes to establishing a scientifically grounded and systematically structured methodology for non-proportional allocation of environmental attributes. Applying MB-CR and B&C models under the requirement and limitation ensures that the non-proportional allocation aligns with the avoidance of environmental burden while maintaining credibility, transparency, and feasibility in environmental claims of industrial materials.

Walking is important for improving physical activity and public health. The pedestrian walkways called Walkways for Health in Shiraz, Iran, present a high standard of aesthetic and design features which attract many people for the purpose of recreation. In addition, a significant percentage of Iranians suffer from mental disorders. The contribution of aesthetic and design features toward walking for recreation as well as mental health has been demonstrated in previous studies, which have focused on either one or the other of these aspects. This interdisciplinary research study aims to evaluate both of these aspects simultaneously. A quantitative approach including a survey questionnaire and multiple regression analysis was used to examine the objectives. The contributions of walking attitudes and several perceived environmental attributes to the attractiveness for walking and to general/mental health were determined, which suggested the need for new arrangements of the visual sequences and social setting along these walkways. In addition, the observation that younger people suffer are more affected by mental health disorders was one of the most challenging findings. The policy makers of this city could apply the findings of this study to these pedestrian walkways in order to improve the attractiveness for walking as well as general and mental health.
