The impact of the Covid-19 lockdown on the human experience of nature

A dataset of acoustic measurements from soundscapes collected worldwide during the COVID-19 pandemic

Political responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium of 261 contributors from 35 countries brought together by the Silent Cities project built a unique soundscape recordings collection to report on local acoustic changes in urban areas. We present this collection here, along with metadata including observational descriptions of the local areas from the contributors, open-source environmental data, open-source confinement levels and calculation of acoustic descriptors. We performed a technical validation of the dataset using statistical models run on a subset of manually annotated soundscapes. Results confirmed the large-scale usability of ecoacoustic indices and automatic sound event recognition in the Silent Cities soundscape collection. We expect this dataset to be useful for research in the multidisciplinary field of environmental sciences.

COVID-19 shutdown revealed higher acoustic diversity and vocal activity of flagship birds in old-growth than in production forests

The COVID-19 shutdown has caused a quasi-experimental situation for ecologists in Spring 2020, providing an unprecedented release in acoustic space for avian soundscapes due to the lowest technophony levels experienced for decades. We conducted large-scale passive acoustic monitoring in 68 forest stands during and after the shutdown to compare their acoustic diversity under different management regimes. We designed a before-after sampling scheme of 18 paired stands to evaluate the short-term effect of shutdown on diel and nocturnal acoustic diversity of forest soundscapes. We assessed whether old-growth preserves hosted higher acoustic diversity and vocal activity of flagship specialist birds than production stands during the shutdown, and whether the effect of management was mediated by landscape fragmentation and distance to roads. We derived acoustic richness and vocal activity of flagship specialist birds by systematically performing 15-min long aural listening to identify species vocalizations from all recorded stands. The end of the COVID-19 shutdown led to a rapid decrease in diel and nocturnal biophony and acoustic diversity. During the shutdown, we found significantly higher biophony and acoustic diversity in old-growth preserves than in production stands. Bird acoustic richness and vocalizations of the two most frequent flagship specialists, Dendrocoptes medius and Phylloscopus sibilatrix, were also both higher in old-growth stands. Interestingly, this positive effect of old-growth stands on forest soundscapes suggested that they could potentially attenuate traffic noise, because the distance to roads decreased acoustic diversity and biophony only outside old-growth preserves. Similarly, flagship bird richness increased with old-growth cover in the surrounding landscape while edge density had a negative effect on both acoustic diversity and flagship birds. We suggest that enhancing the old-growth preserve network implemented across French public forests would provide a connected frame of acoustic sanctuaries mitigating the ever-increasing effect of technophony on the acoustic diversity of temperate forest soundscapes.

Demographic and spatial variables associated with spending time in nature during COVID-19 lockdowns

To stop the spread of SARS-CoV-2 coronavirus (COVID-19) governments around the world implemented lockdowns restricting public travel. In the Australian state of Victoria, this included limiting permitted reasons for leaving home and restricting movements to within a 5 km radius of one's home. In 2020, we conducted a state-wide survey (N = 1024) of Victorians that coincided with a lockdown. We asked respondents where they had spent time in nature and how they perceived lockdowns affected the amount of time they spent in nature. We then considered demographic and spatial predictors of spending more or less time in nature. Women, younger people, and those living in areas with higher socio-economic status were likely to report spending more time in nature. Closer proximity of residents to parks and waterways and higher proportional area of native vegetation within a 1-km radius were also associated with more time in nature. Understanding how different groups were affected by restrictions on access to nature can help improve government management of crises like pandemics, including through urban planning for green space, supporting improved individual and societal resilience. We discuss the implications of our findings for improving access to nature during lockdowns as well as opportunities for a post-pandemic relationship with nature, particularly in urban settings.

An exploration of how the disruption of mainstream schooling during the COVID-19 crisis provided opportunities that we can learn from so that we may improve our future relationship with the more-than-human world

The COVID-19 crisis forced educators globally to reassess delivery of their curricula and educational priorities. Already the worsening climate crisis amid human beings' deleterious relationship with the more-than-human world has caused many educators to demand radical reconsiderations as to the purpose and meaning of education. We ask: how did the disruption of mainstream schooling, during the COVID-19 crisis, provide opportunities that we can learn from so that we may improve our future relationship with the more-than-human world? We examine research that shows children can benefit from outdoor, contemplative pedagogical approaches that differ from their usual indoor classroom experience. Outdoor, contemplative pedagogical approaches involving freedom from "clock-time", as were experienced by some children during the lockdowns, can allow for ways of knowing and states of being that are often marginalised or excluded from mainstream schools in industrial growth societies. We draw on underpinning theory that argues the status quo in schools conforms to a factory model of schooling that prioritises limited ways of knowing and states of being, thus, lacking the perspectives needed to enable children to cultivate a sustained, healthy relationship with nature. We suggest that outdoor contemplative approaches are required that allow children to dwell pedagogically and experience their relationship with the more-than-human world.

COVID-19 lockdown has indirect, non-equivalent effects on activity patterns of Reeves's Pheasant (Syrmaticus reevesii) and sympatric species

The outbreak of the COVID-19 pandemic has brought massive shifts in human activities through a global blockade, directly affecting wildlife survival. However, the indirect impacts of changes in human activities are often easily overlooked. We conducted surveys of Reeves's Pheasant (Syrmaticus reevesii) and its sympatric species by camera traps in forest-type nature reserves in three different scenarios: pre-lockdown, lockdown and post-lockdown. An increase in livestock activities observed during the lockdown and post-lockdown period in our study area provided us an opportunity to investigate the indirect impact of the lockdown on wildlife. The pre-lockdown period was used as a baseline to compare any changes in trends of relative abundance index, activity patterns and temporal spacing of targeted species and livestock. During the lockdown period, the relative abundance index of livestock increased by 50% and there was an increase in daytime activity. Reeves's Pheasant showed avoidance responses to almost all sympatric species and livestock in three different periods, and the livestock avoidance level of Reeves's Pheasant during the lockdown period was significantly and positively correlated with the relative abundance index of livestock. Species-specific changes in activity patterns of study species were observed, with reduced daytime activities of Hog Badger and Raccoon Dog during and after the confinement periods. This study highlights the effect of the COVID-19 lockdown on the responses of wildlife by considering the changes in their temporal and spatial use before, during and after lockdown. The knowledge gained on wildlife during reduced human mobility because of the pandemic aids in understanding the effect of human disturbances and developing future conservation strategies in the shared space, to manage both wildlife and livestock.

Nature's contributions in coping with a pandemic in the 21st century: A narrative review of evidence during COVID-19

While COVID-19 lockdowns have slowed coronavirus transmission, such structural measures also have unintended consequences on mental and physical health. Growing evidence shows that exposure to the natural environment (e.g., blue-green spaces) can improve human health and wellbeing. In this narrative review, we synthesized the evidence about nature's contributions to health and wellbeing during the first two years of the COVID-19 pandemic. We found that during the pandemic, people experienced multiple types of nature, including both outdoors and indoors. Frequency of visits to outdoor natural areas (i.e., public parks) depended on lockdown severity and socio-cultural contexts. Other forms of nature exposure, such as spending time in private gardens and viewing outdoor greenery from windows, may have increased. The majority of the evidence suggests nature exposure during COVID-19 pandemic was associated with less depression, anxiety, stress, and more happiness and life satisfaction. Additionally, nature exposure was correlated with less physical inactivity and fewer sleep disturbances. Evidence was mixed regarding associations between nature exposure and COVID-related health outcomes, while nature visits might be associated with greater rates of COVID-19 transmission and mortality when proper social distancing measures were not maintained. Findings on whether nature exposure during lockdowns helped ameliorate health inequities by impacting the health of lower-socioeconomic populations more than their higher-socioeconomic counterparts for example were mixed. Based on these findings, we argue that nature exposure may have buffered the negative mental and behavioral impacts of lockdowns during the COVID-19 pandemic. Recovery and resilience during the current crises and future public health crises might be improved with nature-based infrastructure, interventions, designs, and governance.

The impact of COVID-19 pandemic and national lockdown on the surgical care of ophthalmic patients in a tertiary health care institution

Introduction/Objective. World Health Organization in January 2020 declared a pandemic of the coronavirus disease named COVID-19. The state of emergency in the Republic of Serbia began on March 15 2020, which greatly influenced the treatment of those patients who were not affected by COVID-19. The aim of this paper is to compare the most common ophthalmic surgeries during quarantine with those performed in 2019 in the same period. Methods. This is a retrospective study. We collected data from the operating protocol of the main ophthalmic operating room. We have followed the changes related to surgical procedures during these two years. Results. During the state of emergency, significantly more operations were performed on male patients than on female patients compared to the same period in 2019 (p = 0.043). In the observed period, in 2019 significantly more patients older than 65 were surgically treated (p < 0.001). During 2019, there were 397 (64.3%) elective and 220 (35.7%) urgent procedures, while for the same period next year there were 9 (9.1%) elective and 90 (90.9%) urgent procedures. Significantly more urgent interventions were performed during 2020 compared to 2019 (p < 0.001). Conclusion. The coronavirus pandemic has led to numerous changes in the treatment of ophthalmic patients. Many patients did not have access to adequate treatment, which certainly led to the impairment of many ophthalmic diseases.
