“…The last few years have seen a surge of interest in quantifying allergenicity of urban green spaces (Hruska 2003 ; Cariñanos et al 2014 , 2017 ; Kasprzyk et al 2019 ; Velasco-Jiménez et al 2020 ; Aerts et al 2021 ). These studies, like our own, are limited by a lack of standardised allergenicity scales, uneven quality of evidence across allergen datasets and knowledge gaps (certain species being more studied than others), which altogether significantly affect risk assessments (Sousa-Silva et al 2021 ; Suanno et al 2021 ).…”

“…Several recent studies have documented a high potential allergenic risk for urban parks and gardens (Cariñanos et al 2017 ; Kasprzyk et al 2019 ; Velasco-Jiménez et al 2020 ), but none to our knowledge has yet studied a standardised ecosystem, nor quantified the variation in risk along an urbanisation gradient. In our lightly managed study system, the observed gradual turnover in allergen species composition reflects a shift in the underlying mechanisms driving plant community assembly in these grassland ecosystems.…”

“…To characterise pollen emission sources and identify the drivers of their spatial distribution, allergenic vegetation must be mapped at ground level. While previous urban studies covered mostly allergy risks of trees and shrubs (Cariñanos et al 2016 , 2017 ; Kasprzyk et al 2019 ; Velasco-Jiménez et al 2020 ; Aerts et al 2021 ), herbaceous vegetation has received less attention (but see Hruska 2003 ), in particular outside parks or in non-managed areas, and never along a well-defined urbanisation gradient.…”

Pollen allergies have been on the rise in cities, where anthropogenic disturbances, warmer climate and introduced species are shaping novel urban ecosystems. Yet, the allergenic potential of these urban ecosystems, in particular spontaneous vegetation outside parks and gardens, remains poorly known. We quantified the allergenic properties of 56 dry grasslands along a double gradient of urbanisation and plant invasion in Berlin (Germany). 30% of grassland species were classified as allergenic, most of them being natives. Urbanisation was associated with an increase in abundance and diversity of pollen allergens, mainly driven by an increase in allergenic non-native plants. While not inherently more allergenic than native plants, the pool of non-natives contributed a larger biochemical diversity of allergens and flowered later than natives, creating a broader potential spectrum of allergy. Managing novel risks to urban public health will involve not only targeted action on allergenic non-natives, but also policies at the habitat scale favouring plant community assembly of a diverse, low-allergenicity vegetation. Similar approaches could be easily replicated in other cities to provide a broad quantification and mapping of urban allergy risks and drivers.

“…Allergic reactions to tree pollen vary from irritation of the upper airways and eyes to severe asthmatic reactions requiring hospitalisation, and sometimes resulting in death (Bosch-Cano et al 2011;D'amato 2000). The impact of allergens emitted by urban green spaces on human health has been extensively studied in the Global North (Cariñanos et al 2019(Cariñanos et al , 2020Velasco-Jiménez et al 2020), but there has been a shortfall of similar studies in the Global South. According to the European Academy of Allergy and Clinical Immunology more than 150 million Europeans (approx.…”

As much as people benefit from the ecosystem services provided by nature, ecosystem disservices also impact daily lives. This is especially true for many urban communities in the Global South due to (1) the often greater diversity of ecosystem disservices and (2) higher vulnerabilities, which together can lead to greater impacts of ecosystem disservices in many Global South settings. This chapter provides an overview of the current understandings of urban ecosystem disservices and their assessment and management with an emphasis on the Global South, albeit with reference to the Global North where useful. This overview reveals a lack of detailed and systematic empirical research on urban ecosystem disservices generally, but even more so in the Global South, despite the greater diversity and vulnerability in Global South settings. This needs to be acknowledged in urban ecology framings of urban dynamics in the Global South and translated into better integration of both ecosystem services and disservices within common research, policy or management frameworks. It is only through such integration that appropriate context-relevant policy directions and management options can be identified, thereby promoting the wellbeing of urban citizens in the Global South.

“…The ornamental flora planted at gardens, parks or streets present a low biodiversity with a massive use of few species from the same families, mainly Oleaceae and Betulaceae in the case of Ourense, which can lead to cross-reaction processes between their allergens in sensitized people [12,13]. Besides the abovementioned, the assessment of pollen emissions from forestry or cultivations surrounding the urban environment should be also considered [14].…”

Allergies became a major public health problem, identified as an important global pandemic with a considerable impact on the worldwide economy. In addition, a higher prevalence of pollen Type I sensitization cases in urban environments in comparison with the rural territories was detected. Our survey sought to assess the main biological pollution episodes caused by the aeroallergens of the major allergenic tree species in urban environments. A Hirst-type volumetric device was used for pollen sampling and a Burkard Cyclone sampler for the detection of tree atmospheric allergens over two years. The main allergens of Alnus, Fraxinus, Betula, Platanus and Olea, were detected in the atmosphere. Three peaks of important pollen concentrations were recorded throughout the year. The developed regression equations between pollen counts and allergen proteins registered great R2 values. The number of days with probability of allergenic symptoms was higher when the pollen and allergen data were assessed altogether. Fraxinus allergens in the atmosphere were detected using Ole e 1 antibodies and the Aln g 1 allergens with Bet v 1 antibodies, demonstrating the cross-reaction processes between the principal allergenic proteins of the Oleaceae and Betulaceae families. Long Distance Transport processes (LDT) showed that pollen from Betula populations located in mountainous areas increased the secondary peaks of pollen and allergen concentrations, and air masses from extensive olive orchards of North-Eastern Portugal triggered the highest concentrations in the atmosphere of Olea pollen and Ole e 1 allergens.
