Green justice in the city: A new agenda for urban green space research in Europe

In this short communication, we discuss European urban green space (UGS) research from an environmental justice perspective. We show that European UGS scholarship primarily focuses on functional values and managerial aspects of UGS, while paying less attention to equity in the enjoyment of and decision-making around UGS. On this basis we discuss potentials for European urban green space research to take up a more explicit environmental justice framing to shed much-needed light on injustices in European cities and inspire change in policy and practice.     

Residents’ perceptions and attitudes toward waste treatment facility sites and their possible conversion: A literature review

The siting a landfill or waste treatment facility and the redevelopment of a brownfield or former landfill site are generally treated as independent issues in the research literature. Nonetheless, the two are important elements of community development and urban revitalization efforts. The purpose of this paper is to provide an integrated review of the current literature on attitudes toward waste treatment sites and their potential conversion for recreation use. We begin by examining research on residents’ perceptions of and attitudes toward proposed and existing waste treatment facility sites, including the perceived impacts and determinants of attitudes toward these sites. Next we summarize work that has explored the subsequent conversion of former landfills or brownfield sites, with a particular emphasis on repurposing these sites for green space and recreation use. We conclude by summarizing key issues and implications for future research and policy development.     

Distribution, habitat and biomass of Pittosporum undulatum, the most important woody plant invader in the Azores Archipelago

Pittosporum undulatum Ventenat (Pittosporaceae) is a tree or shrub native to Australia introduced in the Azores Islands in the 19th century, presently naturalized in the nine islands. According to a random survey of vascular plants in the Azores, the invader is present throughout the archipelago, in 62% of 547 1-km² samples. It was found in pure or mixed stands, forming groups and also as isolated trees. P. undulatum was frequently found in native scrubland (62%), mixed woodland (39%) and hedgerows (25%). The altitudinal range extended from sea level up to about 800 m a.s.l., with the highest frequency between 100 and 400 m. The woody species more strongly associated with P. undulatum included characteristic native and endemic species as well as non-indigenous and invasive taxa. Based on a forest inventory, 49% of the forested area in the Azores, about 24,000 ha, is occupied by P. undulatum. Considerable areas inside Island Natural Parks are covered by this species. The estimated annual P. undulatum biomass production in the Azores might range from only about 150 Mg in the small island of Corvo up to more than 60,000 Mg in Pico Island. The heating value of its wood and its chemical composition make it a good candidate for use in combustion or gasification processes. Since there are no resources available to control this large-scale invasion, using P. undulatum biomass for energy production might be an important factor to stimulate the progressive and sustainable cutting of its stands and its replacement by Macaronesian species.

Effects of the onset of the COVID-19 pandemic restrictions on park crime in London,England: An interrupted time series analysis

IntroductionPark crimes may have increased during the COVID-19 pandemic as a result of lockdowns that limited the number of capable guardians in public spaces. Despite this, the impacts of the lockdowns on park crimes remain unknown. To help us understand the societal impacts of policies implemented during this period, we assessed how the onset of the COVID-19 restrictions impacted urban park crime levels in London, England.MethodsWe identified crimes that occurred in publicly accessible parks and gardens in the Greater London Authority (England, UK) between March 1, 2019 and February 28, 2021 by overlaying open-access crime data with greenspace data supplied by the Greater Information for Greater London service. Using interrupted time series analyses, we estimated seasonality-adjusted associations between the onset of COVID-19 restrictions and park crimes.ResultsOverall (1565.7, 95% confidence intervals [CI] 1021.9 to 2109.5) and antisocial behaviour crimes (1772.7, 95% CI 823.6–2721.7) increased in London parks during the first full month of COVID-19 restrictions (April 2020). There were no notable trends in park crimes in London prior to the onset of restrictions, but overall and antisocial behaviour crimes decreased after the onset of restrictions at a rate of 156.4 (95% CI −220.25 to −92.51) and 164.7 (95% CI −280.68 to −48.74) crimes/months, respectively.ConclusionsOverall park crimes increased during the first full month of the COVID-19 restrictions, largely driven by an increase in antisocial behaviours. Additional research is needed to identify the specific misdemeanours that accounted for this rise in antisocial behaviours and to investigate their downstream impacts (e.g. increases in policing costs or decreases in perceived park safety).
