Perceptions of environmental change and beliefs in the effectiveness of pro‐environmental actions

Effect of water quality on species richness and activity of desert-dwelling bats

In 1988, New York City’s West Harlem community had a problem. The recently opened North River Sewage Treatment Plant, which stretches eight blocks along the Hudson River, was doing a poor job of processing about 170 million gallons of raw sewage daily. Residents were concerned about the foul smells coming from the plant, and parents complained that their children were suffering from respiratory problems. The community knew it needed help, but it also needed something else: information on the exposures it was facing, on the health effects of those exposures, and on the courses of action open to the people. When the community mobilized months later to form West Harlem Environmental Action Inc. (WE ACT), it had taken the first step toward cultivating just that sort of environmental literacy.

Research shows that people’s perceptions of environmental change are strong predictors of ecologically supportive behaviours and attitudes, but less is known about what causes some people to perceive environmental change more than others. This study considers whether participation in outdoor leisure activities accounts for different perceptions of the local environment. We consider how leisure activities form a broader ‘ecological habitus’ while also considering the role that education has in structuring perceptions and practice. We use survey data on perceptions of environmental change and use Principal Component Analysis and logistic regression to explore ecological habitus and the effect of leisure activities on environmental perceptions. Results show that outdoor leisure practices shape perceptions of local environment change and offer a continuum of ecological habitus ranging from appreciative to low resource outdoor leisure associated with varied perceptions of environment degradation. Education is a limited factor in predicting perceptions or explaining associations between leisure and environmental perceptions.

Unplanned urbanization, demographic and environmental changes have forced many cities into more uncertainty and risk, challenging economic, social, and environmental sustainability. In this context nurturing resilience in the face of various uncertainties of environmental, socioeconomic and other sociopolitical risk is an urgent matter. Resilience has become an important goal for many cities throughout the world leading to the enhancement of urban ecology and maintenance of essential ecosystem goods and services to make sure the sustainable future for all. The Kathmandu metropolitan city is one of the fastest-growing capital cities with recent and frequent evidence of unplanned development, loss of green space, tragic events of an earthquake, flood and other environmental problems causing devastation, economic damages, and loss of human life/health, and habitats. In this background, the paper evaluates suitable sites for urban green space development using the analytical hierarchy process (AHP) based multi-criteria analysis methods with geographical information system (GIS).Variables taken for this study are school point data, health facility’s location data, emergency service’s locations, water bodies, emergency road network data, recent land use/land cover data, population data, existing park, and slope. The unit of a study is a metropolitan city. Our evaluations demonstrate the spatial distribution of different not suitable areas, less suitable, moderate suitable, and highly suitable area respectively, of the 4.47%, 7.19% of the area are high and moderate suitable area, while the largest area 78.87% is less suitable and 9.47% are not suitable for the development of green open space. The result indicates human occupancy is everywhere and per capita, open green space in the city is very below the global average. The local government must think about different modality for development of green open space in collaboration with other government agency occupying more open space or engagement with private sectors. This finding could contribute a planner for spatial planning of green space development in a Metropolitan City.

The study of tadpole assemblages allows inferring habitat availability and using their occupation as a means of proxy for the effective reproduction of the species, contributing to complementary information for the study of their adult forms. Environmental variables, represented by abiotic variables, vegetation structure, matrix management, and landscape elements, affect species having reproductive modes associated with oviposition and development in bodies of water. In the Orinoco region, most amphibians have complex life cycles and deposit their eggs in highly dynamic lentic bodies of water. Therefore, it is important to know how larval assemblages change over short periods of water accumulation and their relationship with environmental variables. Fieldwork was conducted during 9 weeks of larval sampling, from the beginning of the rainy season. We evaluate changes in anuran assemblages associated with water accumulation in five temporary water bodies of anthropogenic (road or pasture) and natural (savanna or gallery forest) origin. Twenty environmental variables were evaluated and measured in the center of each water body. Of these, nine landscape variables were measured only once during the study. The other eleven variables, representing management practices, physicochemical and structural characteristics of the water bodies, were measured weekly during the 3 months of sampling. We explored differences in the structure and diversity of larval-stage anuran assemblages using statistical tests suitable for small sample sizes (i.e., permutational multivariate analysis of variance PERMANOVA and the distance-based linear modeling DistLM). Of the 14 species found, two species had remarkedly high abundances from whichRhinella humboldti(19% of the total tadpole abundance) was a generalist inhabiting the natural and anthropogenic water bodies, whileLeptodactylus insularum(18% of the total tadpole abundance) was a specialist at a natural pond in the savanna. The natural water bodies contained the highest number of species (between 10 and 12) and a total abundance of larvae (between 847 and 485 individuals). In contrast, the anthropogenic water body tracks generated by tractors were only occupied by two species with 50 individuals in total, while the water body generated by the trampling of cattle in pastures had three species with 474 individuals. These three species that inhabited the anthropogenic puddles were also found in the natural ponds and none of the eight species of hylids inhabited the puddles. In each field trip, all the tadpoles were collected from the sampled bodies of water. However, a week later, we found that each of the water bodies had been recolonized by four species (Leptodactylus fuscus, Leptodactylus fragilis, Elachistocleis ovalis,andR. humbolti). The variables with the highest explanatory power on the variation of anuran assemblage structure throughout all the water bodies were height of plants, number of cattle, distance to the nearest native forest edge, distance to an anthropic lentic body of water, distance to a natural lentic body of water, and pH. The bodies of water immersed in the natural cover were more diverse and had a greater degree of spatial and temporal species turnover. Our study calls for the importance of understanding the turnover of larval stage anurans over short periods, associated with water accumulation, in highly dynamic systems such as natural ponds and anthropogenic puddles. The importance of species traits and local processes is also highlighted, from environmental variables to human management activities, in the conservation of amphibian assemblages.

Phytoplankton have a crucial role in the conversion of greenhouse gas sources and sinks in natural water bodies, such as lakes, rivers, and oceans. In response to environmental changes, phytoplankton adapt by altering their carbon utilization strategies, which affect carbon fixation rates and carbon fluxes at the water–air interface. This paper classifies and summarizes the main carbon utilization strategies of phytoplankton in terms of carbon acquisition, carbon metabolism, and carbon emission. Their carbon acquisition strategy determines their carbon uptake rate, while their carbon metabolism strategy affects their carbon fixation potential. Moreover, their carbon emission strategy determines the final net carbon fixation. A systematic study of phytoplankton carbon utilization strategies is important for the development of phytoplankton-based wastewater treatment technologies, understanding of algal greenhouse gas fixation, and assessment of greenhouse gas sources and sinks in natural water bodies. This article provides a comprehensive understanding of the ecological role of phytoplankton in natural water bodies and offers valuable references for related research. Furthermore, our research sheds light on the carbon metabolism and emission processes of phytoplankton. By analyzing the carbon metabolism and emission of phytoplankton under different carbon utilization strategies, we can more accurately evaluate the impact of phytoplankton on the carbon cycle in natural water bodies, which can contribute to environmental protection and sustainable development.

Given that funds for biodiversity conservation are limited, there is a need to understand people’s preferences for its different components. To date, such preferences have largely been measured in monetary terms. However, how people value biodiversity may differ from economic theory, and there is little consensus over whether monetary metrics are always appropriate or the degree to which other methods offer alternative and complementary perspectives on value. We used a choice experiment to compare monetary amounts recreational visitors to urban green spaces were willing to pay for biodiversity enhancement (increases in species richness for birds, plants, and aquatic macroinvertebrates) with self-reported psychological gains in well-being derived from visiting the same sites. Willingness-to-pay (WTP) estimates were significant and positive, and respondents reported high gains in well-being across 3 axes derived from environmental psychology theories (reflection, attachment, continuity with past). The 2 metrics were broadly congruent. Participants with above-median self-reported well-being scores were willing to pay significantly higher amounts for enhancing species richness than those with below-median scores, regardless of taxon. The socio-economic and demographic background of participants played little role in determining either their well-being or the probability of choosing a paying option within the choice experiment. Site-level environmental characteristics were only somewhat related to WTP, but showed strong associations with self-reported well-being. Both approaches are likely to reflect a combination of the environmental properties of a site and unobserved individual preference heterogeneity for the natural world. Our results suggest that either metric will deliver mutually consistent results in an assessment of environmental preferences, although which approach is preferable depends on why one wishes to measure values for the natural world.

The study used learning environment variables in investigating changes occurring as students transfer from primary to secondary school, including the role of student sex and school size pathway as influencing factors in changes in learning environment perceptions. The My Class Inventory (MCI) and Questionnaire on Teacher Interaction (QTI) were used in two data-gathering stages, one in the penultimate month of primary schooling and the other in the fourth month of secondary schooling. The sample comprised 1500 students from 47 feeder primary schools and 16 linked secondary schools. The primary schools ranged from very small isolated country schools to larger city schools with hundreds of students. Five different school size transition pathways were defined for analysis: small-to-medium, medium-to-medium, small-to-large, medium-to-large and ‘within-school’ (involving schools with a K-10 structure, but with separate primary and secondary school sites within the same campus). Although the classroom climate in secondary schools was perceived more favourably than in primary schools (especially in terms of less friction and competitiveness), the quality of teacher-student interaction was perceived to deteriorate on most dimensions assessed by the QTI (e.g. a reduction in teachers' leadership, helping/friendly, understanding and student responsibility/freedom behaviours). But changes in environment perceptions across transition varied with student sex and school size pathway. For example, perceptions of class satisfaction across transition deteriorated for girls, but improved for the boys. The findings have implications for administrators and teachers, particularly those with a role within the ‘middle school’ years.

In this study, we investigate perception of likely environmental change as a factor of community adaptive capacity. A comparison of perceived change with science-based assessment of change is proposed to better understand community risk assessment and decision-making. Based on this analysis, we identify shared attitudes and perceptions of change that can be used to develop communication about environmental change in a manner that is appropriate within the context of the community. A community-level survey was conducted to sample differences in individual perception of likely environmental change as well as attitudes regarding climate change and natural resource management among residents of Alaska’s Kenai Peninsula. We compare perceptions of likely environmental change to science-based assessments of change using a conceptual framework that recognizes socio-cognitive processes associated with decision-making. We evaluate the relationship of those perceptions to attitudes using quantitative methods. A binary logistic model is used to investigate the predictive relationship between perception and attitudes regarding climate change and natural resource management. A cultural consensus model is then used to determine areas of shared community perception of change and attitudes. Results of this analysis suggest that despite diverse individual perceptions of environmental change, shared community perceptions and attitudes can be identified.

The epidemiological implications of fresh water snails have continued to pose serious challenge to schistosomiasis control. A survey was conducted to ascertain the species diversity and abundance of aquatic snails in man-made and natural water bodies in Benue state, Nigeria. Eight sites were sampled for the presence of snails using the sweep net and handpicking method. Snails captured were carefully placed into pre- labelled specimen bottles and transported to Benue State University Zoology Laboratory for identification. Plants commonly known to be suitable for snail attachment were collected and brought to the Botany laboratory for identification. The physiochemical parameters of the water were also documented. Data was processed using Analysis of Variance (ANOVA). A total of 1038 snails belonging to 3 species were identified; Melanoides tuberculata, 468 (45.1%), Lanistes libycus 210 (20.2%), Bulinus species 360 (34.7%). Northbank dam harboured 2 (Bulinus and Melanoides) out of the 3 species recorded, making it the most favourable habitat sampled. Bulinus species was the most abundant in the natural habitats while it was replaced by Melanoides tuberculata in the man-made water bodies. ANOVA revealed a significant difference in relation to snail species encountered, and species abundance in habitats sampled (P< 0.05). The predominant aquatic flora encountered were Ipoemoea aquatic and Nelsonia species. The study revealed that natural and man-made water bodies in Makurdi and Ochobo support the breeding of snail species that have serious epidemiological implications.

Perceptions of change in the environment caused by the COVID-19 pandemic: Implications for environmental policy

Environmental and climate change education in Romania from the perspective of international and national strategies in the field. On any society’s way towards sustainable development education plays a fundamental role, by providing knowledge and shaping attitudes. Over the last decades, the education for sustainable development has been increasingly addressed by specific policies at different levels – international, European, national. In this context, this paper aims to briefly review strategies/programs/plans regarding the education for sustainable development at all these levels, with a focus on those in Romania. In order to do this, we surveyed the websites of the UN, the EU, the Ministry of Education and Research of Romania, and read the representative documents on the subject, with the aim of situating developments in the field in Romania in a more general framework, and identifying specific national elements. If internationally, concerns and policies in this field are well-established, in Romania they only date back to the year 2018, as a response to the UN’s 2030 Agenda for Sustainable Development, culminating in 2022 in the development of a strategy for environmental and climate change education. As a way to implement this strategy, the “Green Week” program was introduced in all primary and secondary schools in the country.

Leisure activities positively impact community development including benefits related to enhancing physical health, improving mental health, developing social skills, encouraging creativity, and enhancing quality of life. However, the relationship between leisure activities’ benefits and residents’ motivation to participate in community building remains little explored. To fill the gap, this study constructed structural equation modeling including positive environment changes, residents’ participation, leisure activities, and improving quality of life. The results found three key implications of positive environmental changes in boosting the intention of community participation, including the following: (1) positive environment changes including making more green space, enhancing the aesthetics of community layout, and building more open spaces significantly boost recreational activity demand; (2) leisure activities and their multifaceted impacts lead to improved quality of life contributing to the residents’ intention of community development; (3) the intention of community development participation is strongly influenced by perceptions of the positive changes in physical landscapes and by the mediating role of leisure activities and benefits of the quality of life. The findings provide insight and perspective for policymakers and planners toward sustainable living environments. Additionally, they emphasize the critical role of diverse, accessible recreational opportunities in enhancing the overall quality of life in dynamic residential contexts.

Ours is an age of unprecedented levels of environmental alteration and biodiversity loss. Beyond the exposure to environmental hazards, conditions such as environmental degradation, biotic impoverishment, climate change, and the loss of ecosystem services create important health threats by changing the ecology of many pathogens and increasing the incidence and/or severity of certain noncommunicable conditions. They also threaten health in the future by weakening the Earth's life support systems.Although physicians remain one of the most often accessed and most trusted sources of information about the environment, there is currently little emphasis on educating medical professionals about these environmental issues. This lack of training reduces the ability of most physicians to be efficient science-public interfaces and makes them ineffective at contributing to address the fundamental causes of environmental problems or participate in substantive environmental policy discussions. This is an important challenge facing medical education today.To turn medical students into effective physician-citizens, an already-overwhelmed medical school curriculum must make way for a thoughtful exploration of environmental stressors and their impacts on human health. The overarching question before medical educators is how to develop the competencies, standards, and curricula for this educational endeavor. To this end, the authors highlight some of the critical linkages between health and the environment and suggest a subset of key practical issues that need to be addressed in order to create environmental education standards for the physician of the future.

For cities to make progress on their sustainability goals, a better understanding of community-level perceptions of change are needed because they are a key factor in re-shaping social practices. Drawing on survey data from four Atlantic Canadian cities we look at changing perceptions and practices related to use of public transportation and green spaces. Using social practice theory, we examine whether perceptions of local environmental change correlates with increasing pro-environmental practices. We also assess whether length of time spent in a neighbourhood increases pro-environmental practices and consider the effect of several socio-demographic characteristics. Our results show that perceptions of environmental change and time spent in a neighbourhood affect the likelihood of changing pro-environmental practices. The data offer support for social practice theory as an explanatory framework for understanding changing environmental habits, which can be drawn upon to meet sustainable development goals.
