ABSTRACT

The COVID-19 pandemic has highlighted the importance of incorporating nature-based solutions in urban design, in order to create sustainable and resilient cities. Inspired by these events, the present study aims at exploring the mental health benefits of nature exposure during the outbreak. Secondarily, we investigate changes in use patterns towards urban green spaces (UGS) and urban blue spaces (UBS) and whether extreme conditions, such as these of a lockdown, can lead to an increase in people's appreciation of urban nature. Through an online survey, we observed that the pandemic resulted in a decrease in the frequency of visitation to UGS/UBS (p < 0.001). Significant differences were found for exercise (p < 0.001) and socialization (p < 0.05) as main drivers for visiting urban nature pre- and post-lockdown. Accordingly, visitation rates for forests (p < 0.05), playgrounds (p < 0.001), and the sea (p < 0.001) differed significantly when comparing the two periods. In people's perception, UGS/UBS are important for the urban fabric (89%). Our structural equation model indicated that nature exposure had a beneficial effect on participants' mental health (p < 0.001). Pathways that explain the relationship between nature exposure and post- lockdown value were nature relatedness, motivation, and perceived importance of UGS/UBS. No mediation could be extracted for nature exposure and mental health. Our findings show the positive association between nature exposure and mental health improvement, especially in times of crisis, as well as a shift in the "value domain” towards urban nature.

ABSTRACT

Half of the world's population lives in cities, where usually there are few little green space and there are also high levels of air pollution. Moreover, the traditional urbanization of cities contributes to climate change, promotes the loss of global biodiversity and induces serious health problems for citizens. Both climate change and the loss of biodiversity affect negatively to the ecosystems and therefore human health, as they are responsible for providing clean air, food, fresh water, medicines, renewable resources. . . This deterioration increases significantly the risk of human-borne infectious diseases such as coronavirus or HIV. The ability we have to re-naturalize anthropogenic spaces and learn to generate spaces for coexistence will be key for the future of our society. The research presented in this paper aims to do a step forward to achieve that ability by working in three schools of the city of Barcelona and their surroundings. Among other actions, in this project, a diagnosis of neighborhood has been carried out. The diagnosis includes the identification and quantification of relevant indicators regarding neighborhood's biodiversity and also the quality of daily life and the analysis of pollutants (NO2 and PM10) near the schools during the 2021-2022 school year. All these information has been merged in a single geographic data base and relevant hotspots where to act have been identified. The information has been shared with city council and citizens.

ABSTRACT

During the COVID-19 pandemic, urban green spaces were considered less prone to contagion, and thus people adopted them as alternative sites for improving mental health. The One Health concept advocated by health organizations worldwide supports the idea that the well-being of urban residents is strongly linked with physical activity in green areas. As the world grapples with the physical and mental health consequences of the COVID-19 pandemic, it becomes clearer that access to urban green spaces is a human rights issue. This study compared previously-mapped urban green spaces in five metropolitan regions in Brazil with the results of an extensive survey of municipal managers concerning possible increase in demand of population for green spaces. Urban green spaces of over 625 m2 were mapped in 117 municipalities, the total area of 4170 km2 representing 37.4% of the urban spaces analyzed in the five metropolitan regions. Out of these 117 municipalities, 49 had data available concerning demands of green spaces in the pandemic context. Overall, 20 municipalities (representing all five metropolitan regions) stated that there was an increase in visitation in urban green spaces, and 13 more indirectly suggested possible demands. When sustainability transitions are understood as geographical processes that happen in concrete places, urban green spaces then represent real locations where sustainable transitions can begin. The unequal distribution of these spaces also brings into consideration a social justice perspective, as well as aspects of public health that involve climate change resilience and epidemiological risk (SDG 11). © 2023, Scientific Publishing House of the Cardinal Stefan Wyszynski University.

ABSTRACT

Nowadays, the leisure time of the inhabitants is increasing, meaning that urban green spaces are becoming more and more valuable, as people visit these places more often and for longer periods to spend their spare time there. In the aftermath of the Covid pandemic, these open spaces are playing an even more important role in social interaction. The features used by different groups of the society (sociotopes), the aesthetics and the atmosphere of green spaces all have an impact on the experiences gained in the area, all these may determine our perception and opinion of the given space. The present research aims to show, through the example of Stockholm's green spaces, the factors responsible for good or negative experiences and whether there is any correlation between these and the urban green space types. Stockholm was the first city to win the European Green Capital Award in 2010, showing its leadership in environmental thinking and being a role model for other European, including Hungarian (Budapest, Pécs) cities that have also applied for the European Green Capital Award but were not shortlisted as finalists. Stockholm can also be described as 'part water, part green belt, part city', as stated in an official document published by the European Commission (2010, p. 21). Stockholm ranks highly among European cities in terms of green space accessibility (Buckland–Pojani 2022), Green City Index score and environmental policy (Akande et al. 2019), as well as in terms of public satisfaction with the quality of life in the city (Okulicz-Kozaryn 2013), therefore may serve as a best practice model for other cities. A categorisation of Stockholm's green spaces has been carried out in this study, using Ibes' (2015) paper as a basis. According to this, six categories can be distinguished by using ten variables. The green space categories identified in the analysis show differences in the number of sociotope functions and differences in the temporal (time of day, season, length of stay), frequency (visits to the area) and economic (cost of services in the area) aspects of these categories. © 2023, Teruleti Statisztika.

ABSTRACT

Cities shelter more than two thirds of the world's population, and health security in such environments became a challenge. The outbreak of the SARS-COV-2 pandemic revealed the urgency of assessing urban resilience towards major health crises. Major cities are acknowledged for decreasing the health status of their residents through complex drivers, and researchers from various domains have been addressing these issues for the past three decades. The aim of our study focused on highlighting the main methods and indicators used by scholars to assess the impact of urban landscapes on health, and to cluster urban landscapes based on their conclusions. We scoped the scientific literature published in the past 10 years, addressing the issue of health in relation with urban landscapes. We used statistical approaches, API algorithms, and social network analysis for generating and exposing our results. Most studies focused on perception analyses (mainly self-perceived health), literature reviews or environmental quality impacts on health. Green and blue features were considered therapeutic landscapes, while dense built-up spaces were described as harmful. Urban landscapes are acknowledged as enablers or disablers of health, thus planning strategies and regulations should consider the impacts generated by the design and structure of new urban fabrics. © 2023, Editura Universitatii din Bucuresti.

ABSTRACT

Urban parks provide a multitude of health benefits for citizens navigating the challenges of 21st-century living. And while this is well known by both scholars and practitioners, there is less understanding about the differential impacts of park size, type of facilities, community accessibility, and management. This is the central concern of the research reported here, which is a part of a larger project titled 'Better Parks, Healthier for All?' funded under the UKRI-NHMRC Built Environment and Prevention Research Scheme 2019. Within this broader context, the current paper discusses the results of a focus group to better understand how different park qualities promote physical and mental health. Using a COVID-safe research approach, we brought key park providers, park policymakers, and green and open space designers from New South Wales, Australia, together to participate in an online focus group in May 2021. The recruitment was based on the domain expertise and practitioner knowledge of the issues at hand. The ensuing discussion canvassed three areas of interest: What is park quality? How is park quality associated with health? How can we assess park quality and its ability to deliver health outcomes? A thematic analysis of the group's deliberations reveals a very holistic appreciation of park quality. The ability of a park network to provide a range of health outcomes is central to this view, with each park playing a role in delivering different benefits across the network. Our findings indicate that there are many opportunities to enhance the myriad of benefits and multiple ways to gain them. Co-design is essential to ensure that parks best suit the local context and provide relevant benefits to all stakeholders. In this way, local communities can gain ownership and enhanced agency in relation to using and enjoying their parks. We conclude that delivering locally networked parks and associated spaces for community health and wellbeing are essential in the broader context of global environmental sustainability.

ABSTRACT

The COVID-19 pandemic has caused significant changes in public and human activities worldwide, including using masks and reducing human interaction. These changes have also affected wildlife behavior, especially in urban areas. However, there is limited understanding of the impact of COVID-19-related human activities, mainly mask wearing, on the behavior of urban bird species. This case is intriguing in the Philippines, where COVID-19 restrictions and mask wearing have been more prolonged than in other countries. We studied two common urban bird species (Geopelia striata and Passer montanus) in Southcentral Mindanao, Philippines, to assess their response to mask wearing by examining their alert distance (AD) and flight initiation distance (FID). We found that birds had a reduced FID to mask wearing, but only significantly in G. striata (Zebra Doves) and not in P. montanus (Eurasian tree sparrow). The effect of the variables related to urbanization on FID was contrasting. For example, ambient noise increased bird vigilance while proximity to roads reduced bird FID in urbanized areas, but their effects were weaker compared to mask wearing. We conclude that mask wearing during the COVID-19 pandemic is a significant environmental element that alters bird escape responses in urban areas, and the effects may be species-specific.

ABSTRACT

Urban green space (UGS) provides multiple cultural ecosystem services (CES) and enhances people's physical and mental well-being. The importance of UGS was more critical during crisis periods such as the COVID-19 pandemic. Recently, UGS has been under severe threats due to rapid urban expansion and climate change. Particularly, the cities in developing countries have experienced a dramatic loss of green spaces due to land use and land cover (LULC) change. This study aims to assess the impact of the COVID-19 pandemic on CES perception obtained from two public UGS, i.e., Subhankar Sishu Uddyan (SSU) and Bandh Road (BR) in English Bazar Urban Agglomeration (EBUA), Eastern India. A survey was performed to assess the valuation of CES, CES obtained from UGS, and the use of CES difference during partial (unlock phases) and after lockdown periods. The non-parametric tests were carried out to understand the significant differences between CES and UGS perceived by the respondents. Explanatory factor analysis was also performed to find the association among CES for each UGS. The results reported substantial variations of UGS use during partial and after lockdown periods. During the after-lockdown period, the UGS mainly were used for social relations (51%), spending time with relatives and friends (25%), spending time with children (11%) in SSU and walking (25%), spending time with relatives and friends (21%), and physical activities (17%) in BR. During the partial lockdown period, a significant difference between SSU and BR was recorded from social relations and health value among all CES. After the full lockdown period, a significant difference was observed in recreation, social relations, health, and aesthetic value. The frequency and duration of UGS use during partial lockdown periods substantially increased. About 12% of the total visitor visited UGS daily after the lockdown, whereas it was 4% during the partial lockdown. The study's findings will assist urban planners and policymakers in understanding the need for UGS to promote the well-being of the citizens.

ABSTRACT

Some policies implemented during the pandemic extended the time that students spend on electronic devices, increasing the risk of physical and eye strain. However, the role of different environments on eye strain recovery has not been determined. We recruited 20 undergraduate students (10 males and 10 females) from a university in eastern China and explored the restoration effects of their eye strain in different types of spaces (wayside greenspace, a playground, a square, and woodland) on campus through scale measurements. The results showed that the eye strain of the students accumulated by 15 min of e-learning was significantly relieved after 10 min of greenspace exposure compared to the indoor environment, and the recovery effect varied depending on the type of landscape. The effect of eye strain relief was found to be positively correlated with temperature, wind speed, visible sky ratio, canopy density, tree density, and solar radiation intensity, while it was negatively correlated with relative humidity. These findings enrich the research on the restoration benefits of greenspaces and provide a basis for predicting the effect of different environments on the relief of eye strain. © 2022 by the authors.

ABSTRACT

The limited access to urban green spaces during the COVID-19 pandemic had a negative impact on the human-nature interaction in cities and human well-being. Number of visitors to green areas, initially declined due to imposed restrictions, was restored after they were lifted as established by several studies across the globe However, little is still known about changes in behavior and preferences of park visitors in the post-COVID time. In this study, we investigated spatial-temporal patterns of recreational activities in the three urban parks in Moscow (Russia) prior, during and after the COVID-19 lockdown (in 2019 and 2020). The selected parks represent two different types: a centrally located park with much infrastructure and open landscapes (Gorky Park) and parks located at the outskirts of the city center with a more forested landscape and little infrastructure (Timiryazevski and Sokolniki parks). Recreational activities were identified based on the analysis of social media photos using machine-learning algorithms. As expected, park closures during lockdown resulted in overall decrease in the number of taken photos. After the parks were re-opened, however, the number of photos did not grow immediately. The number of photos only restored after almost three months, and the visiting peak shifted to autumn. Differences between parks were related to the type of the park and its landscape structure. The lowest decrease in the number of photos was observed for the Timiryazevsky park - a semi-natural green area, while the centrally located Gorky Park was the most affected, likely due to the strictest control measures. In comparison to 2019, photos in 2020 were more evenly distributed across the area in all the three parks. Besides, 'natural' areas became the main attractors for the visitors - photos under 'nature observation' category became the most popular. Spatial distribution of the recreational activities in post-lockdown period was characterized by larger distances between photos, likely corresponding to the social distancing. COVID-19 pandemic highlighted the value of green areas for citizens, but also changed their recreational preferences and overall behavior in parks. The observed shift from high density of visitors around entertainments and attractions in 2019 to a more homogeneous and less dense distribution along the natural zones in 2020 reveals a new pattern in visitors behavior and preference, which shall be considered in spatial planning of the parks. Increasing availability of natural green areas and their integration in urban green infrastructures can become the most relevant policy to consider the crucial role of urban nature as a source of resilience in turbulent times.

ABSTRACT

SARS-CoV-2 (COVID-19) has spread all over the world, significantly affecting our everyday lives. People changed their habits during the pandemic and made use of urban green spaces (UGS). Our Web of Science and Scopus queries confirm a knowledge gap in green space planning and public space management studies in the field of UGS availability during COVID-19. Therefore, the purpose of our research was to determine the impact of the COVID-19 pandemic on urban green spaces management, identify the needs of the residents in terms of urban green spaces furniture, and assess the accessibility of urban green spaces to propose recommendations for the institution charged with managing urban green spaces in the City (Krakow). To this end, we used an expert interview, spatial analyses, and survey research among residents of Kraków, one of the largest cities in Poland. The survey involved 1350 respondents. The spatial analyses employed geoprocessing algorithms and GIS tools. The results showed that 96% of Kraków citizens have access to urban green spaces within 300 m from their homes. Therefore, UGS are an important part of the City's identity, making their reasonable management vital, especially during crises. The respondents indicated that the existing UGS needed more lighting, rubbish bins, and benches as places of respite. Results of the expert interview showed that the COVID-19 pandemic has affected urban green spaces management. The results may influence urban green spaces management, and the research is an innovative combination of spatial analysis, a qualitative approach (expert interview), and a quantitative method (a survey) proposing new procedures for analysing UGS. © 2022 John Wiley & Sons Ltd.

ABSTRACT

The pandemic issue is frequently discussed in the news or mass media. In 2002, Ebola, SARS, and SARS-CoV-2 were highly infective viruses that caused a global pandemic, according to the pandemic chronology. Animals in the forest spread each of these viruses to people. Since the 1918 influenza pandemic, the unique human coronavirus COVID-19 has caused the fifth documented pandemic. In this era, there has been an increase in public awareness about urban green spaces. Many studies suggest that proper landscape planning and design with a sustainable mindset may provide a helpful and responsive environment for healthy urban improvement during pandemic crises. Thus, this study aims to look into the functions of urban green spaces for long-term environmental health, especially during pandemic crises. The research revealed that urban green spaces improve immune system performance, promote social capital and cohesiveness, reduce mortality, lengthen life expectancy, and potential adverse health impacts. The findings also emphasised various advantages of urban green spaces during pandemics, such as enhanced mental and physical well-being, less risk of disease transmission, and enhanced social cohesion. In summary, urban green space sustainability may support a healthy environment and lifestyle in metropolitan areas amid pandemic crises. © 2023 Institute of Physics Publishing. All rights reserved.

ABSTRACT

Positive sentiments towards urban green spaces (UGS) unequivocally increased worldwide amid COVID-19. In contrast, this paper documents that views on mobility restrictions applicable to UGS are of a contested nature. That is, while residents unambiguously report positive sentiments towards UGS, they do not share views on how to administer access to UGS-which is a matter of public policy. These contesting views reflect opposite demands that managers of UGS had to balance during the pandemic as they faced the challenge of reducing risk of spread while providing services that support physical and mental health of residents. The empirical analysis in this paper relies on views inferred through a text classification algorithm implemented on Twitter messages posted from January to October 2020, by urban residents in three Latin American countries-Argentina, Colombia, and Mexico-and Spain. The focus on Latin America is motivated by the documented lack of compliance with mobility restrictions; Spain works as a comparison point to learn differences with respect to other regions. Understanding and following in real-time the evolution of contesting views amid a pandemic is useful for managers and city planners to inform adaptation measures-e.g. communication strategies can be tailored to residents with specific views.

ABSTRACT

This paper seeks to examine how the perception and use of Nairobi's urban green spaces (UGS) have been impacted by the Covid- 19 pandemic. The question of how the current pandemic and the resulting government policies will affect urban green spaces has remained elusive. Similarly, the relationship between public health crises and urban green spaces has not been well integrated in the current literature. This paper identifies a nexus between government response to the Covid-19 pandemic and (Un) sustainability of UGS. The authors further reflect on the potential role UGS could play to mitigate the negative effects of the pandemic. Findings of the study show that UGS in Nairobi have not been fully exploited to provide citizens with sufficient access to green spaces yet as the pandemic has shown these spaces could significantly improve physical and mental health for the citizens as well as act as logistical areas for humanitarian activities during a pandemic. The paper therefore concludes with policy recommendations that can give rise to short and long term reforms in the provision and management of UGS.

ABSTRACT

During the first waves of the Covid-19 pandemic period, urban environments were stressed;the resilience of our cities were tested, highlighting the strengths and weaknesses of the urban contexts, not always capable to promote and protect the population health status. Urban Green Spaces (UGS) have proved essential role as “tools” to improve Urban Public and Mental Health. Unfortunately, the heterogeneous distribution of UGS inside the contemporary cities, together with the disparity in quality of such spaces, led to some exclusion phenomena. The paper would describe a research experience based on four consequential phases: theoretical background update;tool definition phase (Quantitative assessment: Proximity of the UGS in Milano, and Qualitative assessment: RECITAL 2.0 Milano);application phase in the urban context of Milano city and findings analysis. About the application phase, 24 parks were evaluated: by the comparison of the “RECITAL 2.0 Milano” results with the UGS surface data, no significant pattern emerges, that means that environmental quality is not linked to the extension of the UGS. By the comparison of the overall score with the average real estate values in the analyzed area, emerges an easily readable and expected correlation: the top-performing parks are in the most exclusive areas of the city, often in or near the city center, easily reachable by public transportation alternatives. Qualitative assessments can detect criticalities in-side the urban environment, while quantitative assessments can find areas of the cities deprived of the benefits of UGS. The overlap of both findings could be an indicator of the presence of some form of exclusion phenomena, thus requiring attention both of Urban Planners and Policy Makers to ensure healthier and more equal urban environments. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Following an ambitious urban renewal program that began in the late 1980s, Barcelona has become a major tourism destination in the Mediterranean. As an emerging global city, planners in Barcelona today are greening the city through park improvements, street re-designs and street traffic-calming initiatives. While striving to provide locals with green amenities, these beautification projects have also produced unexpected consequences, as they bring in more visitors and accelerate gentrification. Currently, few city greening projects can avoid discussions of gentrification, and neighborhood groups have begun to organize in opposition to the touristification that has made their neighborhoods unaffordable and/or exclusive. While the current COVID-19 pandemic has drastically reduced the number of visitors to Barcelona-producing a new experience for local residents-the impacts on local street life, public space, housing and gentrification trends remain uncertain. © 2022 selection and editorial matter, Isabelle Anguelovski and James J.

ABSTRACT

This paper describes an attempt to utilize paid citizen science in a research project that documented urban park usage during the early stages of the COVID-19 pandemic in two U.S. cities. Strategies used by the research team to recruit, pay, and evaluate the experiences of the 43 citizen scientists are discussed alongside key challenges in contemporary citizen science. A literature review suggests that successful citizen science projects foster diverse and inclusive participation;develop appropriate ways to compensate citizen scientists for their work;maximize opportunities for participant learning;and ensure high standards for data quality. In this case study, the selection process proved successful in employing economically vulnerable individuals, though the citizen scientist participants were disproportionately female, young, White, non-Hispanic, single, and college educated relative to the communities studied. The participants reported that the financial compensation provided by the study, similar in amount to the economic stimulus checks distributed simultaneously by the Federal government, were reasonable given the workload, and many used it to cover basic household needs. Though the study took place in a period of high economic risk, and more than 80% of the participants had never participated in a scientific study, the experience was rated overwhelmingly positive. Participants reported that the work provided stress relief, indicated they would consider participating in similar research in the future. Despite the vast majority never having engaged in most park stewardship activities, they expressed interest in learning more about park usage, mask usage in public spaces, and socio-economic trends in relation to COVID-19. Though there were some minor challenges in data collection, data quality was sufficient to publish the topical results in a peer-reviewed companion paper. Key insights on the logistical constraints faced by the research team are highlighted throughout the paper to advance the case for paid citizen science.

ABSTRACT

In Greek cities, urban green spaces are scarce and well below acceptable standards. However, policy makers and planners are not prioritizing long-term planning strategies for urban green and do not attempt to engage citizens in relevant decision-making and urban planning processes. In this context, a web-based public survey was conducted in the city of Thessaloniki (Greece) during the COVID-19 pandemic, aiming to identify citizens' attitudes, satisfaction levels, actual behaviour and future expectations about urban green spaces (UGS). It also aimed to measure the effect of COVID-19 (mobility) restrictions on UGS visitation. All these issues were explored through a spatial lens, by developing measurable and mappable results suitable for future urban planning decisions. According to these results, citizens tend to report a very low satisfaction level about the current state of UGS (in terms of their adequacy and quality), and they tend to travel a great distance to reach an urban park (about 2 km on average). Moreover, the results indicate that spatial differences are very significant in terms of UGS availability and accessibility. Another important outcome of this study is that, unlike in other cities, the frequency of visiting green spaces in Thessaloniki did not increase during the pandemic. On the contrary, a slight downward trend was observed, maybe due to the combined effect of restriction measures and the lack of proximity/availability of UGS to local population groups. The maps produced in this study may thus facilitate well-informed planning decisions related to the development of new green projects.

ABSTRACT

A recently conducted study by the Centers for Disease Control and Prevention encouraged access to urban green space for the public over the prevalence of COVID-19 in that exposure to urban green space can positively affect the physical and mental health, including the reduction rate of heart disease, obesity, stress, stroke, and depression. COVID-19 has foregrounded the inadequacy of green space in populated cities. It has also highlighted the extant inequities so as to unequal access to urban green space both quantitatively and qualitatively. In this regard, it seems that one of the problems related to Malatya is the uncoordinated distribution of green space in different parts of the city. Therefore, knowing the quantity and quality of these spaces in each region can play an effective role in urban planning. The aim of the present study has been to evaluate urban green space per capita and to investigate its distribution based on the population of the districts of Battalgazi county in Malatya city through developing an integrated methodology (remote sensing and geographic information system). Accordingly, in Google Earth Engine by images of Sentinel-1 and PlanetScope satellites, it was calculated different indexes (NDVI, EVI, PSSR, GNDVI, and NDWI). The data set was prepared and then by combining different data, classification was performed according to support vector machine algorithm. From the landscaping maps obtained, the map was selected with the highest accuracy (overall accuracy: 94.43; and kappa coefficient: 90.5). Finally, by the obtained last map, the distribution of urban green space per capita and their functions in Battalgazi county and its districts were evaluated. The results of the study showed that the existing urban green spaces in the Battalgazi/Malatya were not distributed evenly on the basis of the districts. The per capita of urban green space is twenty-four regions which is more than 9m2 and in twenty-three ones is less than 9m2. The recommendation of this study was that Türkiye city planners and landscape designers should replan and redesign the quality and equal distribution of urban green spaces, especially during and following COVID-19 pandemic. Additionally, drawing on the Google Earth Engine cloud system, which has revolutionized GIS and remote sensing, is recommended to be used in land use land cover modeling. It is straightforward to access information and analyze them quickly in Google Earth Engine. The published codes in this study makes it possible to conduct further relevant studies.

ABSTRACT

Urban green spaces' well documented role as a hub for physical and mental health was enhanced by restrictions to mobility issued worldwide as a response to COVID-19. In this context, managers of urban green spaces (UGS) were prompted to provide controlled access under impromptu safety protocols. This unprecedented challenge required planning and operational strengths reflecting flexibility, innovation and learning. These management features are essential for an adaptive governance - an underdeveloped research topic within the study of UGS. Using eighteen semi-structured interviews from six countries, we analyze adaptive governance as reflected by UGS managers' responses across Latin America - a region where access to UGS is a matter of public health and of environmental justice. We document responses that can be categorized based on the governance arrangement in place. On one hand, both polycentric and dedicated-management governances have been able to learn through piloting ideas, adapting personnel roles and the function of UGS infrastructure, and adjusting their decision-making process. On the other hand, managers within municipal public services areas - the most prevalent governance arrangement across Latin America - report difficulty to adapt - likely due to their dependence on political will, limited autonomy, insufficient budgets, absence of formal paths to self-funding, shortage of technical know-how, and insufficient citizens' involvement. We discuss implications of UGS adaptive governance in terms of capacity to deal with future public health, climate-related or other types of shocks.
