“…Moreover, we found significant effects of greenspace abundance on respiratory disease hospitalization, so understanding how spatial variability of air quality affects respiratory disease also requires further research ( 71 ). As vehicular traffic increases, anthropogenic volatile organic compounds (VOCs) combine with plant-based biogenic VOCs as precursors to ground-level ozone, which damages the human respiratory system ( 42 , 72 – 74 ). Since vegetation composition differs between heavily urbanized and forested, less-urban areas, not understanding how much biogenic VOCs are produced by different types of vegetation or how it affects human health may weaken or otherwise bias results ( 73 , 74 ).…”

IntroductionAs the world becomes increasingly urbanized and human-nature contact declines, urban greenspace's impact on human health has garnered growing interest across academic disciplines. Various definitions and multiple indicators of greenspace have been utilized, with most studies finding an overall positive association between greenspace and health. Nevertheless, studies directly comparing how different greenspace indicators impact different disease types have been limited. Moreover, to verify the robustness of conclusions drawn, studies should compare multiple measures of greenspace across various spatial scales. Thus, a more comprehensive analysis is necessary to help inform future study design, especially in determining which greenspace indicators would be most useful in data-limited areas.MethodsChengdu, the capital city of Sichuan Province, is West China's largest and most urban city, being typical of other large cities in lower to middle-income countries (LMICs). With twenty county-level jurisdictions spanning various degrees of urbanization, Chengdu's landscape heterogeneity and large population make it ideal for studying greenspace's impact on public health. This study took Chengdu as a case study to assess the association and potential impact of three traditional measures of greenspace (Normalized Difference Vegetation Index, Enhanced Vegetation Index, and Fractional Vegetation Cover) and urban ratio (% of population being urban) on hospitalization rates and medical expenses paid for three major disease categories (circulatory system diseases, neoplasms, and respiratory system diseases).Results and discussionWe found greenspace did have a significant impact on public health, but this relationship differed by disease type. Greenspace exhibited significant positive association with respiratory diseases, but insignificant negative associations with the other disease categories. Urban ratio showed significant negative association with greenspace abundance. The higher the urban ratio (e.g., less greenspace), the more money was paid on medical expenses. This relationship was found not only in terms of urban ratio being positively correlated with medical expenses, but also in that all three greenspace indicators were negatively correlated with medical expenses. Consequently, in future health outcome studies, urban ratio could be an acceptable negative indicator of greenness in LMICs where urban ratio is likely to imply less greenness.

“…Moreover, trees emit monoterpenes, which can generate ozone and secondary organic aerosols that worsen air quality. 203,204 Trees produce pollen and other antigens that can induce allergies 205 and exacerbate asthma. 206 Moreover, in urban environments, trees could increase humidity, which can worsen the effects of heat.…”

Accumulating evidence suggests that living in areas of high surrounding greenness or even brief exposures to areas of high greenery is conducive to cardiovascular health, which may be related to the environmental, social, psychological, and physiological benefits of greenspaces. Recent data from multiple cross-sectional, longitudinal, and cohort studies suggest that living in areas of high surrounding greenness is associated with a lower risk of all-cause and cardiovascular mortality. High levels of neighborhood greenery have been linked also to a decrease in the burden of cardiovascular disease risk factors as reflected by lower rates of hypertension, dyslipidemia, and diabetes. Those who live in greener environments report better mental health and more frequent social interactions, which can benefit cardiovascular health as well. In this narrative review, we discuss evidence linking greenspaces to cardiovascular health as well as the potential mechanisms underlying the beneficial effects of greenspaces, including the impact of vegetation on air, noise and light pollution, ambient temperature, physical activity, mental health, and biodiversity. We review literature on the beneficial effects of acute and chronic exposure to nature on cardiovascular disease risk factors, inflammation and immune function, and we highlight the potential cardiovascular effects of biogenic volatile organic compounds that are emitted by trees and shrubs. We identify current knowledge gaps in this area and underscore the need for additional population studies to understand more clearly and precisely the link between greenness and health. Such understanding is urgently needed to fully redeem the promise of greenspaces in preventing adverse environmental exposures, mitigating the effects of climate change, and creating healthier living environments.

“…Care must be taken when designing NBS to ensure that unforeseen negative consequences on air quality or other important factors, such as biodiversity, do not arise. For example, trees could worsen pollution levels by preventing circulation of airflow or by producing air pollution themselves (e.g., pollen or biogenic volatile organic compounds) (Liu et al, 2022), and afforestation with non-native monocultures can negatively impact biodiversity and result in maladaptation (Seddon et al, 2020). Even though maintenance of NBS can be lower than that of traditional infrastructure, for interventions to be successful in the long-term, funding for adequate maintenance must be set aside during the design phase (Le Coent et al, 2021).…”
