The Impact of Socio-Demographic Variables on the Daily Use of Leisure Time by Adults in Poland with a Particular Focus on Older People

The sphere of leisure time fulfils important roles in human life, translating into the quality of life of the individual and society. Hence, comprehensive research is being conducted on the ways in which different age groups, including older people, use leisure time. However, few of them take into account factors related to the place of residence, which are important for respondents’ leisure time activities. This study aims to fill the gap in this regard. The aim of the article is to identify socio-demographic variables determining the way adults spend their leisure time, with a particular focus on older people in selected border municipalities in Poland. The study included 1068 individual questionnaire questionnaires completed in 2021 by respondents of border municipalities. One of the non-probability techniques was chosen as the method for selecting elements for the sample, namely, the quota method, which took into account the following characteristics of the population: age, gender, and place of residence. The analyses used selected methods of descriptive statistics and multivariate comparative analysis. The results confirmed that leisure use varied by gender, age, and education. The research also showed that, in the case of older people, leisure time use is influenced by elements relating to their place of residence. Particularly important were the development of green areas in the municipality, safety in the municipality, and the cleanliness of recreational sites.

Individual capture history affects site use and defensive behavior of foraging eastern copperheads at a recreational site

To maximize energy available for foraging or reproduction, optimality theory suggests individuals allocate energy toward defensive behaviors equivalent to risk of predation. In this framework, repeat encounters with humans by wildlife that do not reduce individual fitness could result in a decreased defensive response toward humans in subsequent encounters. We investigated whether individual experience influenced the defensive behaviors and frequency of site use of foraging eastern copperheads (Agkistrodon contortrix) at Koomer Ridge Campground in the Daniel Boone National Forest, Kentucky. Beginning in 2015, this site has been used for annual mark-recapture studies of copperhead foraging ecology as they predate emerging annual cicadas (Neotibicen tibicen). Using a standardized behavioral trial, we tested how copperhead defensive behavior toward humans was influenced by capture history, body size, and soil temperature. Model averaging results indicated that the overall intensity of copperhead defensive response to humans increased with capture history length, and soil temperature was positively associated with likelihood to respond when touched. Number of years recaptured was a significant, positive predictor of foraging frequency in 2022. Therefore, copperheads with longer capture histories visit the site to forage more frequently and are more willing to defend their opportunity to forage, suggesting a degree of acquired tolerance absent from naïve snakes that fled readily. Collectively, these results provide evidence that eastern copperheads at our site modulate their foraging and defensive behavior based on previous capture experience to more efficiently predate a seasonally abundant prey item.

Valuing the nature-based recreational benefits of Iloilo river esplanade using the travel cost method

This paper presents the assessment of the economic value of the Iloilo river esplanade, a recreational site in Iloilo City. The objective of the study is to evaluate the demand for the site or recreation therein using the travel cost method. Data was gathered through online surveys of 385 college students from five universities in Iloilo City who had visited the place. By employing a negative binomial model, the analysis resulted in an estimated economic value of Php 5,120.33 (US$ 93.9) per person per trip. Variables such as travel costs, age, distance, group size, sex, and the visitor’s civil status are significant factors on the number of trips to esplanade. Travel cost has a negative relationship with the trip’s frequency and distance is a factor affecting the number of visits undertaken, indicating that as the as the trip distance increases, the total number of trips decreases. The results presented in this study can improve the quality of the recreational and environmental services of the Iloilo river esplanade, as the findings can assist in identifying the variety of services that the place could offer based on the visitors’ demand. Further, the study can provide valuable inputs in resource and policy planning, as well as assist resource managers and the local government of Iloilo City in making crucial decisions to improve the overall experience for visitors to the Esplanade and ensure the continued preservation of the recreational site to maximize its nature- based and recreational benefits.

Differences in Public Perceptions of Recovery in Different Urban Forests Based on Birdsong

Urban forests are important public recreation sites and play an important function in urban biodiversity conservation. Recent studies have found that urban forests have a beneficial effect on public physiological and psychological health. Birdsong in urban forests has good physiological and psychological recovery benefits and is also the most frequent natural sound. In this paper, a blank group, visual perception, and audiovisual perception were studied by investigating birds in five kinds of urban forests and simulating their birdsong environment. The results showed the following: (1) The visual perception and audiovisual perception of urban forests are restorative to the public’s physiology and psychology. Forests and urban parks with higher natural elements have relatively strong physiological and psychological recovery benefits, and roadside green spaces with higher artificial elements have relatively weak recovery benefits. However, both natural and artificial urban forests can show better recovery. (2) Birdsong perception preference has a mediating effect on the recovery benefit of heart rate and a moderating effect on the recovery benefit of skin conductance, which can affect the recovery benefits of urban forests on public physiology and psychology. (3) Because people’s perceptions of the timbre of birdsong vary, the benefits of birdsong on recovery are not always favorable. The richness and pleasantness of birdsong in the forest environment are significant contributors to the recovery advantages and the likability and comfort of birdsong in the rest of the setting. Based on differences in the composition of birds in different urban forest environments, this study simulated the birdsong environment with birds based on field research and studied the public perception recovery of the urban forest visual environment and the urban forest and birdsong audiovisual environment in order to explore the influence of birdsong on the public health recovery properties of urban forests. This study provides an optimal strategy for the selection and construction of forest healing functions and promotes the development of urban ecosystems and biodiversity.

Mobility and non-household environments: understanding dengue transmission patterns in urban contexts.

Households (HH) have been traditionally described as the main environments where people are at risk of dengue (and other arbovirus) infection. Mounting entomological evidence has suggested a larger role of environments other than HH in transmission. Recently, an agent-based model (ABM) estimated that over half of infections occur in non-household (NH) environments like workplaces, markets, and recreational sites. However, the importance of human and vector mobility and the configurations of urban spaces in mediating the effects of NH on dengue transmission remains understudied. To improve our knowledge of the relevance of NH in transmission, we expanded an ABM calibrated from field data in Kenya to examine movement of people and vectors under different spatial configurations of buildings. In this model, we assessed the number of people traveling between HH and NH and their distance. Those were studied on three different urban configurations, on which the NH are spatially distributed either randomly (scattered), centered (in a single center), or clustered (in more than one cluster). Across simulations, the number of people moving is a major influential variable where higher levels of movement between HH and NH increases the number of cases. In addition, the number of cases is higher when NH are scattered. Intriguingly, the distance that people travel from HH to NH seems to have little effect on dengue burden; however, it affects the level of spatial clustering of cases. These results highlight the importance of NH as a major spreader of infections between HH and NH environments supporting the relevance of NH in transmission and its interaction with human movement in driving dengue dynamics.

Urban Development Together with Girls and Young Women

Public spaces are crucial to everyday life, providing sites for community interaction, mobility, and recreation. Traditionally, however, urban planning has been shaped by a gendered perspective that privileges masculine assumptions that overlook intersectional needs and reinforce societal inequalities for women and girls. This special issue, ‘Let Her Guide You’, developed in partnership with UN-Habitat as part of the Her City initiative, underscores the imperative of incorporating gender and youth perspectives into urban planning and design. The Her City Initiative, a collaboration between UN-Habitat and the Shared City Foundation, advances this goal by equipping urban actors worldwide with tools to integrate the perspectives of girls and young women into urban development. Launched in 2021, the Her City Toolbox has supported over 350 independent initiatives with registered users in 120 countries, demonstrating its effectiveness in fostering inclusive urban environments. This special issue features papers by young academic scholars selected from the Her City Master students alumni network, including case studies of feminist planning from Heerlen (The Netherlands), Nairobi (Kenya), Stockholm (Sweden), and Weimar (Germany). It also includes a diverse range of invited viewpoints advocating for collaborative approaches to urban development together with girls and young women, complemented by illustrative case studies from around the globe, including Belgium, Iran, Italy, Jamaica, Mozambique, Palestine, Peru, South Africa, Sweden, Thailand, Uganda, and the United Kingdom. By centring gender and youth perspectives in the urban planning process, this special issue highlights the potential to transform public spaces into more equitable, engaging, and sustainable environments. It calls on city makers, researchers, and community leaders to ensure that contemporary cities are designed with and for everyone.

Soil reclamation of cranberry plantations on reclaimed lands in Arkhangelsk region

In the production conditions of the "Arkhangelsk cranberry" in the Arkhangelsk region, the land use analysis was carried out as a part of land use monitoring in this agricultural production. In 2015, the first cranberry plantations were planted, and in April 2023 about 40 hectares of peatlands were already in land use of the factory including 8 fields (checks) with an average area of 1 hectare. An assessment of the dynamics of change on the area of the created plantation was carried out for all indicators such as the length of roads, developed area and some separately designed structures (except of drained bogs). It was found that the soil indicators of peatlands are normal for this type of lands, and provide favorable conditions for growing cranberries. The analysis of the dynamics of land use in the period from 2015 to 2023 revealed the following dynamic indicators: an increase in the area of active land use by 418.97%, an increase in the area of drained swamps by 310.68%, 5.5 hectares were withdrawn from the forest fund, 42.31 hectares are under development (complex works), the total number of checks for planting increased by 23 parcels, an increase in the length of roads, including dirt roads, by 8.6 km, an increase in the number of fire ponds by 3 pieces, an increase in the number of sludge ponds by 3 pieces, and, finally, 1 recreational site was commissioned. The research has also shown that drainage does not lead to a significant change in the chemical composition of the organic part of peat and its agrochemical properties, so using drainage is not rational. In this case, a slight change in the water-air regime was observed together with the changes in the soil-forming process, and some activities of microorganisms, which was a prerequisite for an increase in the level of mineralization of the organic part of peat. Despite the gradual commissioning of peatlands, environmental sustainability has a trend towards an increase, which should be taken into account in the further development of the enterprise.

Uncovering disparities in water-based outdoor recreation using cell phone mobility data

Abstract Outdoor recreation plays a pivotal role in improving people’s physical and mental health, serving as a popular form of entertainment and a significant economic contributor. Limited access to these resources not only exacerbates health disparities but also deprives underserved areas of essential benefits like stress relief and community bonding, both of which are crucial for enhancing overall quality of life. This paper provides one of the first detailed analyses of water-based recreation at over 61 000 inland and coastal sites across the United States. We aim to explore disparities in recreational behavior across race, ethnicity, income, and socioeconomic status. Using Advan cellphone data from more than 70 million outdoor trips, representing 215 000 census block groups, we find that communities of color, rural areas, and socioeconomically disadvantaged groups are significantly underrepresented in water-based recreational visits. Despite living similar distances from recreational sites, these groups show notably different patterns in travel distance for water-based recreation. Additionally, we find Native Americans from underserved areas have to travel 3–5 times longer distances than other groups for water-based recreation. Our findings show that the extensive and frequent cellphone mobility data could reveal policy-relevant patterns especially those made by underserved Americans often overlooked in traditional household surveys.

Assessing the impact of Escherichia coli on recreational water safety using quantitative microbial risk assessment

ABSTRACT Recreational water activities have become an integral part of society for entertainment, health, and fitness. The water quality for these activities plays an integral role in the health and safety of the participants. This study aimed to monitor the presence of Escherichia coli in selected recreational water bodies, specifically rowing in the Gauteng Province of South Africa. Water samples were collected (upstream, midstream, and downstream) from three recreational water sites, i.e., Klip Rivier, Wemmer Pan, and Germiston Lake, monthly from May to October 2022. The presence of E. coli was determined using the Colilert® Quanti-Tray®/2,000 (IDEXX) assay and ChromoSelect agar. Pathotypes were confirmed using a multiplex PCR. The MPN for E. coli from all the samples exceeded the recommended guidelines of <2,000 microbes/100 mL. Pathogenic E. coli was detected in all three sites, with EPEC, ETEC, EAEC being most prevalent. The E. coli isolates showed 66% ESBL resistance and 94% carbapenemase resistance. Risk assessment showed recreational activities (rowing and swimming) posed a significant health risk as exceeded the annual risk benchmark limit of 1 × 104. The results obtained provide insights into the health risk associated with recreational activities within these water bodies and highlight the need for seasonal monitoring.

Ticks and Tick-Borne Pathogens in Popular Recreational Areas in Tallinn, Estonia: The Underestimated Risk of Tick-Borne Diseases.

This study reveals a significant presence of ticks and tick-borne pathogens in urban recreational areas of Tallinn, Estonia. During the period of May-June 2018, 815 Ixodes ticks were collected from an area of 11,200 m2 using the flagging method. Tick density reached up to 18.8 ticks per 100 m2, indicating a high concentration of ticks in these urban green spaces. Pathogen analysis demonstrated that 34% of the collected ticks were infected with at least one pathogen. Specifically, Borrelia burgdorferi s.l., the causative agent of Lyme borreliosis, was detected in 17.4% of the ticks; Rickettsia spp. was detected in 13.5%; Neoehrlichia mikurensis was detected in 5.5%; Borrelia miyamotoi was detected in 2.6%; and Anaplasma phagocytophilum and tick-borne encephalitis virus were detected in 0.5% each. These findings indicate that the prevalence and abundance of ticks and tick-borne pathogens in these urban environments are comparable to or even exceed those observed in natural endemic areas. Given the increasing incidence of Lyme borreliosis in Central and Northern Europe, the risk of tick bites and subsequent infection in urban recreational sites should not be underestimated. Public health measures, including enhanced awareness and precautionary information, are essential to mitigate the risk of tick-borne diseases in these urban settings.

Games4Justice: Game Reports

Four games were designed as part of an autoethnographic, teacher research study conducted from 2013-2017 on the implementation of play-, game-, and design-based teaching and assessment. The study was conducted at two urban, independent, K-12 day schools with fewer than 500 and 100 students, respectively, and supported as part of a certification program in Serious Game Design & Research. Pirate Oasis, a six-week ecological engagement, human development game, and the first developed for the Games for Social Justice Course (G4J). Friendship Is Magic, a Alternate Reality Game (Fujimoto, 2015; McGonigal, 2003, 2007, 2011) that was never played. #SaveOurGirls is a 3-hour forum game, simulation & workshop on combating human trafficking through public pedagogy. The experience is meant for 10-15 players and 30-60 audience members. Xplore LA, a location-based, geocaching, two-dimensional fighting game, designed by students to inspire young people to explore their local parks and other green- and play-spaces in park-poor communities in Los Angeles, like Boyle Heights. Xplore LA was designed as one of three projects organized to engage youth to access recreational sites near them via public transportation in the park-poor community of Boyle Heights. Through the campaign, students also developed a Ross Valencia Park Redesign, a Pocket Park Manual and the foundations for Xplore LA.

The Combined Effects of the Thermal Environment and Air Quality at Recreation Places on the Physiology and Psychology of People in Urban Parks

Urban forests, crucial to urban ecosystems, are increasingly threatened by the challenges of urbanization, such as deteriorating thermal environments and declining air quality. Despite their recognized benefits to city dwellers’ quality of life, a systematic understanding of the impact of these environmental factors on public psychophysiological well-being in recreational sites is a notable gap in the literature. The objective of this research was to bridge this gap by examining the effects of the thermal environment and air quality in urban forests on the public’s perception, offering scientific evidence to inform environmental optimization and health management strategies for urban parks, essential for sustainable urban development and public health. Three urban parks in Fuzhou, Fujian Province, namely Fuzhou National Forest Park, Xihu Park, and Jinniushan Sports Park, were selected as research sites. Environmental monitoring and questionnaire surveys were conducted at 24 recreation places from October to December 2020, collecting temperature, humidity, and wind speed; the atmospheric composition includes PM2.5, PM10, negative oxygen ion, and psychophysiological data from the public. Multivariate statistical methods were employed to assess the environmental characteristics of different recreation places types and their impact on public health. The findings reveal that environmental factors explained 1.9% to 11.8% of the variation in physiological and psychological responses, mainly influenced by temperature, wind speed, and negative oxygen ions. Forests and waterfront recreation places significantly outperform canopy and open recreation places in promoting mental invigoration, stress relief, emotional tranquility, and attention restoration. Environmental monitoring results indicate that favorable meteorological conditions and good air quality are crucial for enhancing the service functions of recreation places. Notably, the positive correlation between a negative air ion concentration and psychological well-being provides a novel perspective on understanding the health benefits of urban forests. The thermal environment and air quality of urban recreation places exert a significant influence on the psychophysiological status of the public. Increasing green coverage, improving water body environments, and rationally planning recreation places layout are of great theoretical and practical significance for enhancing the environmental quality and service functions of urban forests.

Natural Causes of Sport and Recreation-Related Deaths in the General Population: A 14-Year Review in Québec, Canada

This study analyzed trends in the frequencies and rates of natural deaths associated with sport and recreation activities in Québec, Canada, from January 2006 to December 2019, and investigated their etiology and characteristics. This descriptive retrospective study utilized data from coroner reports, as well as autopsy and police reports. Activity-specific incidence rates were calculated using participation data from the Étude des blessures subies au cours de la pratique d'activités récréatives et sportives au Québec (ÉBARS) and Canadian census population data. A total of 297 natural deaths occurred, resulting in a population-based death rate of 0.26 per 100,000 person-years. The participation-based rate was 0.23 per 100,000 participant-years, focusing only on the 24 matching activities in both editions of the ÉBARS. Cycling (20.5%; n= 61), ice hockey (8.8%; n= 26), and hunting (8.1%; n= 24) were associated with the highest frequencies and rates of death. Most of the deaths (95.3%; n= 283) were of cardiac origin, with acute coronary syndrome and malignant cardiac arrhythmia identified as the most common causes. Automated external defibrillators were unavailable at 65% of death sites, and bystander cardiopulmonary resuscitation was performed in 60.9% of cases. Men accounted for the vast majority (92.6%; n= 275) of deaths. Death rates increased starting from age 35, peaking in males 45 and over. Efforts aimed at screening for cardiovascular risk factors and ensuring the widespread availability of automated external defibrillators at recreational sites, including remote areas such as hunting territories, could reduce the incidence of natural deaths associated with sport and recreation activities in Québec.

Assessment of the contamination by carbonaceous anthropogenic particulates and polycyclic aromatic hydrocarbons (PAHs) concentration in recreational areas of an estuary heavily industrialized in Northern Spain

The commercial management of coal and its by-products has the potential to negatively impact natural coastal environments. The coal conversion processes and coke production are sources of polycyclic aromatic hydrocarbons (PAHs) emissions that also contribute to the pollution of those aquatic environments. This research assesses the contamination by carbonaceous anthropogenic particles and by polycyclic aromatic hydrocarbons of some recreational sites (Arañón, Peña del Caballo and San Balandrán area) located in the Avilés' estuary, an area in Northern Spain that has been heavily industrialized since the 1950s. The results obtained indicate a low concentration of solid organic anthropogenic particles in the intertidal sediments of the recreational sites in the estuary, probably due to the protective measures set in place at the facilities managing bulk coal and coke, which prevents the dispersion of coal dust (and other materials) as well as the eventual failure into the estuary. The characteristics of 16 priority pollutants PAHs analyzed in two recreational sites of the estuary (San Balandrán area), their distribution by aromatic ring number together with their diagnostic ratios demonstrate a pyrogenic nature with a main source from processes of coal and coke conversion (including combustion) in the facilities around the estuary. Some contribution of PAHs derived from petroleum cannot be ruled out. This contamination by PAHS is constant and sustained over time. The majority of the considered PAHs are well above the Spanish Generic Reference Level, (GRL) established for “protection of ecosystems with aquatic organisms”, and only a few of them are notably above the corresponding Spanish GRL established for “other uses of land”, which should include lands for recreational activities. The analysis of the potential toxicity risk of PAHs for human health and the organisms of the aquatic ecosystem suggests a relatively low toxicity risk to very high toxicity risk in the San Balandrán environment according to the concentration and distribution trend of PAHs identified in this area. This trend is dependent on the coastal dynamics and the protection level of the site, which also affect the distribution of the anthropogenic carbonaceous particulates in the same way.

The Use of Unmanned Aerial Vehicles in the Documentation of Recreation Areas Within The Scope Of Cultural Heritage: The Example of The Ancient City Of Kilistra

Historical buildings have been damaged by natural events and human hands for centuries. For this reason, the importance of studies on the preservation, documentation and restoration of historical buildings is increasing all over the world. In addition, the use of technological opportunities is also becoming important in order to carry out more comprehensive studies on the sustainability of historical buildings. Studies on modeling many cultural heritage (CH) works around the world continue. In order to evaluate these models in reconstruction studies, precise data about the structure must be obtained. In parallel with technological developments, the measurement sensitivity of the devices used in this field has also increased. In addition, different technological tools that will assist in measurement activities are entering our lives day by day. Unmanned Aerial Vehicle (UAV) systems are one of them. 3D data obtained from UAVs and photogrammetric systems are sensitive data obtained quickly and at low cost. This data provides the opportunity to be used in interdisciplinary studies. This study investigates the use of UAVs in the digital documentation study of the Ancient City of Kilistra in Konya/Gökyurt. The results of the study showed that UAVs are much more practical and effective than traditional measurement techniques. It has been revealed that, if appropriate conditions are provided, UAVs can be a suitable alternative in terms of time and cost in documenting recreational CH sites. Finally, it has been determined that the high-resolution digital maps obtained not only speed up the process of documenting large areas, but also provide advantages in terms of accuracy and precision.

Non-linear associations between noise level and people's short-term noise annoyance in different activity contexts

Recent research has become increasingly interested in the on-linear associations between noise levels and people's short-term noise annoyance. However, there has been limited investigation into measuring short-term noise annoyance and how different activity contexts may affect these non-linear associations. To address this research gap, this study measured people's short-term noise annoyance using real-time Ecological Momentary Assessment (EMA) data and the Day Reconstruction Method's (DRM) recalled data. Corresponding noise levels were captured using Global Positioning Systems and portable noise sensors. Employing the Shapley additive explanations method, we examined the non-linear associations between noise level and people's real-time and recalled noise annoyance across different activity contexts. The results indicated that 1) People had greater sensitivity to noise levels in real-time annoyance (non-linear association threshold: 60 dB) compared to recalled annoyance, which had a higher non-linear association threshold of 70 dB. 2) The non-linear associations between noise level and people's real-time/recalled noise annoyance varied between different activity contexts. People tended to be more sensitive to noise in real-time annoyance than recalled annoyance on travel routes and at workplaces. 3) Among the factors examined, the contribution of noise level varied across activity contexts. Noise level contributed more significantly to people's real-time noise annoyance in outdoor recreational sites and on travel routes. These findings enhance our understanding of the non-linear association between noise level and people's short-term noise annoyance, moving beyond the linear paradigm. Policymakers should consider the non-linear relationships and different activity contexts when implementing noise control measures.

Participation of Local Communities in the Management of Post-Mine Areas in Cities

The management of post-mining reservoirs as part of urban blue infrastructure is linked to the implementation of pro-environmental policies at different levels (from local–municipal to European). Local communities, as beneficiaries of measures taken by city authorities, recognise the need for active participation in decision-making processes. They engage in making decisions on blue spaces in urban areas. These include public and natural watercourses and their surroundings, but also water-filled basins of various origins, including post-mining pits. This paper strives to answer how local communities are involved in activities for developing and managing post-mine areas filled with water within city limits. The methods used (including field observation, spatial analyses, and desk research) allowed us to classify post-mining pits according to their functions and the degree of social participation in their development process. The analysed post-mining pits were divided into three groups. The first group consisted of pit reservoirs transformed with the participation of local inhabitants into recreational grounds. The second comprised reservoirs transformed under local zoning plans (with residents consulted) expected to ultimately prop up the city’s green infrastructure. In turn, the third group consists of quasi-natural reservoirs deemed natural enclaves by city residents. The environmental analysis showed that pits were naturalised. One of them was subject to legal protection on account of biodiversity. Post-mine areas in Bydgoszcz play an important environmental role, and some are integral recreational sites, e.g., the Balaton reservoir. They materially affect the inhabitants’ daily contact with nature, which improves life quality.

Projektowanie zakładu uzdatniania wody przy wsparciu modeli laboratoryjnych

The subject of the research focused on the possibilities of supporting the design of surface water treatment plants using laboratory models. Within the pilot study, the possibilities of using different water treatment processes in the treatment of water from the water reservoir Nové Mlýny in the Czech Republic were assessed. The planned treatment plant is to supply a future recreational site from a shallow reservoir with significant eutrophication and chemical industry in the drainage basin. Coagulation, sedimentation, dissolved air flotation, membrane filtration processes and adsorption on granular activated carbon were investigated. These processes were identified by the preliminary study as applicable to water treatment and it was necessary to determine which could be applied given the site conditions. Laboratory models for the individual processes were used during the laboratory testing. During the research, problems encountered were debugged and the models were modified and some extensions were added to the original models. The coagulation and sedimentation processes were investigated using conventional jar tests. The dissolved air flotation process was simulated using a modified jar test and a lab scale model. Different types and doses of coagulants, mixing parameters and residence times were investigated in the tests. Turbidity value was used as an optimization parameter due to its rapidity of determination and low cost. For some tests, potassium permanganate oxidizability (also known as the permanganate index) was also used as an evaluation parameter so that different evaluation parameters could be compared. In addition, for the dissolved air flotation process, the parameters of the produced sludge - its quantity, suspended solids content and chemical oxygen demand - were monitored. These parameters are crucial for discharge of waste water into the sewer and its costs. The adsorption tests on granular activated carbon were performed as batch tests. The evaluation parameter was the manganese index. Another possible variant of activated carbon tests is a continuous flow-through column. These columns also allow monitoring of the process of fouling and the evolution of the effluent over time. The pilot project then used the results of the laboratory tests to create a design for a treatment plant in the area of interest and selected parts of the project documentation. The pilot project demonstrated the usefulness of laboratory testing as a tool to support the design of drinking water treatment plants. At the same time, these tests allow for a faster and more certain identification of the appropriate water treatment technology and thus reduce the extent of semi-operational testing at the site, leading to a more efficient use of funds by investors.

Preferences for urban greenspace functions during public health pandemics. Empirical evidence from Malawi

Purpose The purpose of this study was to investigate the impact of Corona virus disease on the perceived values of urban green landscapes in a developing country setting. To achieve this objective, the author investigated changes in the preferences for urban green space services among city residents who use nature areas for recreation. Design/methodology/approach This study applied the best–worst scaling technique to elicit changes in the preferences for ecosystem services from urban recreational sites in Malawi. The study also used a fractional logit model to examine factors that motivate visitors’ willingness to donate/contribute to improve the quality of nature’s recreational services. Findings This study finds that the COVID-19 pandemic changed visitors’ perceptions of urban woodlands, but leisure/recreation remained the most important service with or without the Corona virus outbreak. However, the perceived value of air pollution control and cultural/religious functions gained more prominence (+3%), whereas biodiversity conservation became less prominent (−2%) during the pandemic period. The mean willingness to pay (WTP) was estimated to be US$28.73, and WTP is positively influenced by education, income status and the user’s satisfaction with the recreation site. Originality/value The study substantiated the impact of Corona virus disease on the perceived values of urban green landscapes, using Malawi as a case study. This was demonstrated through the changes in preferences for urban green space services among city residents who use nature areas for recreation.

Not for all: Barriers to universal accessibility in nature-based tourism and recreation spaces across British Columbia, Canada

The health and well-being benefits of nature contact are inequitably distributed. Among other communities, persons with a disability have fewer opportunities to engage in nature contact in a self-determining way due to the presence of interlocking physical, informational, service, policy, and attitudinal barriers. The purpose of this project was to utilize accepted accessibility standards to document the state of accessibility in nature based tourism and recreation spaces across British Columbia. Following community-based research practices, a team of academic researchers and experts working in accessibility practice collected over 6,700 unique measurements documenting potential barriers across 124 outdoor tourism and recreation sites. Of the 974 infrastructure elements and features assessed, fewer than five percent met all required standards. This paper shares evidence about the categories of infrastructure that are most problematic from an access and inclusion perspective, as well as those that are comparable brightspots. Results demonstrate a considerable gap between Canada's policy goal to become barrier free by 2040 and the present state of accessibility in outdoor spaces across the nature continuum. Management ImplicationsOrganizations managing outdoor tourism and recreation spaces across the nature continuum in British Columbia, Canada are not meeting interrelated moral, legislative, and social demands for equitable access to nature. Management agencies should invest in data collection completed in partnership with the disability community to reveal the full suite of barriers that prevent access across the province. New capital investment programs are required to upgrade legacy infrastructure and realize new features and amenities that provide meaningful opportunities to all. To ensure accessibility does not diminish over time, changes in management practices like incorporating accessibility requirements into operational contracting, hiring for lived experience, and building accessibility monitoring into maintenance planning and operations are needed.
