“…The worldwide densification of urban areas, also in industrialised countries, is often accompanied by the disappearance of existing green spaces. At the same time, research has highlighted the benefits and positive impacts of UGSs on urban residents [48]. These trends support the approach of studies that make spatial reference to urban masks in the sense discussed here.…”

At a time of rising urbanisation and climate change, urban green spaces (UGSs) are an essential element to help adapt to extreme weather events. Especially in urban core areas, heat and drought are regarded as human stress factors. The delineation of such areas constitutes an important reference geometry in topographic geodata (urban mask). This article deals with possibilities for investigating UGSs in European cities—based on unified urban masks—by applying city-wide metrics to Copernicus data (Urban Atlas including the Street Tree Layer). Both public and tree-covered urban green spaces are examined in detail. Selected results are presented for 30 European cities that display a wide range of urban structures. The spatial reference to uniformly delineated urban masks places the analytical focus of city-wide metrics onto corresponding core areas. In general, the values of UGS metrics vary considerably between cities, indicating the strong influence of city-specific factors on urban structures in Europe. For the comparative analysis of tree-covered urban areas, the Urban Green Raster Germany and a municipal tree register are used to provide additional data sources. The regular updating of the Copernicus dataset means that green spaces in European cities can be monitored, also using urban masks.

“…A comprehensive bibliometric analysis of UGS research over the last three decades by Farkas et al (2023) found that scientific studies have increasingly focused on inner-city areas. The worldwide densification of urban areas, also in industrialised countries, is often accompanied by the disappearance of existing green spaces.…”

“…Despite their high sensitivity and robustness, chromatographic and spectrographic techniques are expensive, and require tedious sample preparation procedures, costly reagents, and professional operators (Qiu et al, 2019). Effective sample preparation and outcome can take hours or days to arrive, potentially delaying reporting, thereby limiting their application in field settings and in developing countries for food safety and quality analysis (Dirpan et al, 2023). there is an urgent need to develop simpler and faster detection devices to effectively prevent foodborne diseases (Weng & Neethirajan, 2017).…”

Food microfluidic paper‐based analytical devices (µPADs) are powerful tools to create total analysis systems and have long been demonstrated to be useful for safety and quality applications. Thanks to new technological innovations food µPADs offer exciting new possibilities. This review introduces how µPADs are obtained from chromatography, filter, or office papers and detect analytes from a food sample. We introduce the most current developments in the use of µPADs with an emphasis on paper types, adapted new technologies, and detection limits. Classifications are also made on food µPADs according to applied innovations and adapted novel technologies. In the first section, simple forms of µPADs for the detection of pathogen, mycotoxin, pesticides, and other food components are discussed with technical details. Then, we introduce multisensing approaches for high throughput analysis and a concise summary will be given. In the case of three‐dimensional (3D) µPADs, the use of 3D is discussed and compared to 2D µPADs in terms of its advantageous with the example of a food colorant test device. In the following section, smartphone adoption to µPADs is introduced in detail with eight different assay examples. Centrifugal platform for nickel assay is demonstrated as an enabling approach with shortened assay times by rotational velocity. The potential of user‐friendly hybrid devices is also summarized in the last part. Finally, we present an outlook to underline the opportunities created by smartphone‐based and intelligent µPADs for food safety and quality with real success perspectives

“…Previous research has analysed urban vegetation at different scales [31][32][33][34] . For instance, some large-scale assessments based on pre-classified land cover data have been carried out 35,36 , although these are largely lacking ground-level validation and do not distinguish between public and private green spaces.…”

Tracking green space along streets of world cities

Street green space (SGS) - the presence of vegetation along streets of cities - is an increasingly relevant indicator for sustainable cities. SGS provides a set of local services such as mitigating the urban heat island effect and reducing the impact of extreme precipitation events, while it is also associated with increasing human well-being. Here we present a global analysis of recent trends in SGS based on modelling a street-based indicator of vegetation density (the Green View Index, GVI) with high-resolution multispectral satellite data and additional granular data. Estimating local to continental trends between 2016-2022 based on 190 large cities distributed across seven macroregions, we find that globally SGS has decreased by almost two percent. Statistically significant changes in city-level median SGS (p<0.01) are found in approximately one-quarter of the cities analysed. However, the direction and magnitude of trends both show a high level of heterogeneity between regions, which we explore by assessing SGS inequalities within each city. Our analysis provides an updated picture of SGS across world cities and an open-source, validated approach to assess its future changes in near real-time and support the design of policies for greener cities.
