‘Lockdown’ periods in response to COVID-19 have provided a unique opportunity to study the impacts of economic activity on environmental pollution (e.g., NO2, aerosols, noise, light). The effects on NO2 and aerosols have been very noticeable and readily demonstrated, but that on light pollution has proven challenging to determine. The main reason for this difficulty is that the primary source of nighttime satellite imagery of the earth is the SNPP-VIIRS/DNB instrument, which acquires data late at night after most human nocturnal activity has already occurred and much associated lighting has been turned off. Here, to analyze the effect of lockdown on urban light emissions, we use ground and satellite data for Granada, Spain, during the COVID-19 induced confinement of the city’s population from 14 March until 31 May 2020. We find a clear decrease in light pollution due both to a decrease in light emissions from the city and to a decrease in anthropogenic aerosol content in the atmosphere which resulted in less light being scattered. A clear correlation between the abundance of PM10 particles and sky brightness is observed, such that the more polluted the atmosphere the brighter the urban night sky. An empirical expression is determined that relates PM10 particle abundance and sky brightness at three different wavelength bands.

Abstract The paper presents results of research on light pollution in the night sky of Toruń. A permanent network of measuring stations has been established in the city, consisting of 24 sites representing various types of land development and land cover: single-family housing, city centre, multi-family housing, areas overgrown with vegetation and open areas. Within this network, a repeatable direct measurement of the sky brightness using an SQM photometer was carried out over a period of three consecutive months in the summer season, i.e. from June to September 2017. The measurement sessions were conducted in similar weather and astronomical conditions. Based on the obtained data, a spatial distribution of light pollution was determined, ranges of values obtained during the measurements were provided, and the results were additionally referred to the distinguished land cover categories and land development types.

Identity, space and emotions, although traditionally all traditionally naturalized and delinked from the construction of one another, might also be read as formed by intertwined processes that are guided and shaped by hegemonic powers. Nonetheless, as they delineating difference within and among themselves, the consideration of these three fields and the way they work together in these shaping opens up new ways to approach the split between normative categories of identity, assigned location and adequate feelings, and their subjective perception. Tessa McWatt’s novel This Body presents the reader with two Guyanese characters, Victoria and her nephew Derek, that undergo, at many different levels, this split between subjectivity and a socially and culturally given subject position. Challenging normative ideals, Victoria struggles with her categorization as Other; an endeavour marked by her trajectories and experiences as she negotiates and redeploys a physical as well as a social space of her own in the city of London. Still, her love relationship with a British man would make her drift towards assimilation inasmuch as this affair relocates Victoria within dominant gender, ethnic and class hierarchies.

Abstract In this article we reflect on the development of an educational fieldwork conducted along the Ipiranga River, in which we bring the debates concerning History of Science and Environmental Education closer together, by problematizing the social and environmental issues in the city of São Paulo in a contextualized and critical way. To that end, we established the limits for the hydrographic basin by highlighting the headwaters of the Ipiranga River and the changes it has undergone, as well as the political, sanitary and environmental meanings throughout the 20th Century. We associated the environmental issues with the history of two important institutions located along the river: The Botanical Garden and the Museu Paulista’s [São Paulo Museum] arboretum. We highlighted the practices, techniques and scientific representations that were developed on the sites, by valuing them as cultural heritage of the Brazilian science.

Zaruma is host to the ‘‘El Sexmo’’ tourist mine, the galleries of which extend below the city, and its exploitation dates back to precolonial times. The mining boom created important development in the area, but informal mining also emerged causing environmental issues and safety problems. This study presents a qualitative and quantitative assessment of the “El Sexmo” Tourist Mine in the context of its potential as a tourism geosite and mining site. The methodological stages included: (i) The process and systematization of the general mine information and its surroundings; (ii) the assessment of the geological and mining interest of the mine, through GAM and Brilha method; and (iii) description and proposal of action strategies through Delphi analysis and a Strengths, Weaknesses, Opportunities, and Threats (SWOT) matrix. Based on the results of the quantitative evaluation, the high values in the educational, scientific, and tourist aspects of the two applied methodologies, show the mine as a potential geosite and mining site with added cultural value. In addition, the quantitative assessment in correspondence with the qualitative analysis, allowed to propose improvement strategies to take advantage of the geological resources and mining identity of the area, as an alternative that strengthens the infrastructure of the mine and consolidates the geotouristic development of the area.

Areas that are considered human-friendly are green spaces. The existing urban parks are designed to fulfill the role of relaxation, recreation, and entertainment. However, in many cases, these are historic places, which at the time didn't have much of an impact on external factors. Sustainable development issues are related to the quality of life and the usage of the environment and its resources by present and future generations. Noise and noise protection is an issue that is part of sustainable development. The inadequate implementation of the principles of sustainable development and non-inclusion of noise can noticeably lead to negative effects now and in the future. The aim of the paper is to analyze the soundscapes of two Bydgoszcz parks located in the city center. The values of the equivalent sound level for these areas were obtained from the existing Bydgoszcz acoustic plan. Subsequently, the resulting distribution of noise was compared with the results of subjective perception of sounds by visitors. On this basis, conclusions can be drawn regarding the ways of shaping such areas while taking into account the perception of visitors.

For the past decades, environment and its relevant issues are becoming the greatest concern of most countries. Public opinion becomes the interest of most policy makers and sociologist reformist. Improved understanding of public perceptions about global warming and other environmental issues can contribute to informing scientific and policy discussions. The aim of this study is to assess the (1) the extent of concern on the major environmental issues of the city (2) the preference between environmental protection and energy production, and (3) to compare the extent of concern of the public according to their respective district.  A total of 1151 respondents, ages 18 and above was derived using the systematic sampling at 95% confidence interval, and proportionate sampling distribution to ensure representativeness with the population of the city. The results suggest that Dabawenyos are greatly worried about global warming (92%), deforestation and urban flooding (88%), and energy crisis are considered as the most alarming environmental problem in the city. Moreover, they are more favorable to environmentally-friendly solutions in addressing the city’s energy problem, and the government should put greater emphasis on the development of renewable energy (96%). The degree of concerns and emphasis on environmental protection of the community can be directly equated to the traumatic environmental phenomena that had happened in the city.   Keywords: Ecology and Conservation, environmental issues, renewable energy, poll survey, Philippines

AbstractA night-sky luminance survey was carried on in Beijing to assess the level of light pollution. The luminance of the zenith night sky and skies in four directions at six sites with different distances from the city center was measured by using a photometric luminance meter. The Xinglong Station of National Astronomical Observatory was included to study the impacts of city lights on an astronomical observatory. The survey shows that the night-sky luminance decreases with increasing distance from the city center. Measurement results indicate that outdoor lighting in the Xinglong county town which is close to the observatory has non-negligible influence on the night sky at Xinglong Station.
