“…Noise mitigation is of course not the only ES that urban woodland provides. The removal of particulate air pollution is another good example of an urban woodland ES that is highly context-dependent, with greater service provided by trees in areas with greater atmospheric concentrations of particulates [40,41]. Indeed, there may well be some synergies amongst the numerous ES provided by urban woodland and more generally, urban green space (UGS).…”

Noise pollution from road traffic is ubiquitous in modern cities and is the second greatest environmental risk to health in Western Europe. Urban woodland can provide substantial noise mitigation if located properly, yet such considerations are often absent from the urban planning process. Current approaches for quantifying this important ecosystem service (ES) do not account adequately for important spatial factors and are unable to identify effectively the best locations to place new woodland for noise mitigation. We present new methods, in which we exploit the concept of least-cost-distance, to map and value the mitigating effect of urban woodland, and to identify optimal locations to place new woodland. Applying these methods, we show that urban woodland currently provides Birmingham City (UK) with over GBP 3.8 million in noise mitigation benefits, annually. We also show that our new ‘opportunity’ mapping methods effectively identify the best locations for new woodland, achieving close to a maximum service with less than a quarter of the additional woodland needed to achieve it. This has important implications for the design and implementation of urban tree planting for noise mitigation, and these methods can be adapted for other ES, allowing consideration of multiple service outcomes.

“…To quantify the amount of PM 2.5 removal by urban vegetation, we gathered the data for PM 2.5 concentration derived from the Global Estimates of Fine Particulate Matter [47] and then applied the method developed by [48,49] to quantify the PM 2.5 removal for the six cities. In addition, to simulate the air pollutant removal service in the future under different scenarios, we took the average PM 2.5 concentration of the latest five years to calculate the removal rate.…”

“…where PMr is the quantity of PM 2.5 removed per unit area of forest and grassland per year (kg ha −1 yr −1 ), PMc is the annual concentration of PM 2.5 (µg m −3 ), and α and β are the regression coefficients, where their values are 1.1664 and 0.4837 ( [48,49]), respectively.…”

Urban expansion and ecological restoration policies can simultaneously affect land-cover changes and further affect ecosystem services (ES). However, it is unclear whether and to what extent the distribution and equity of urban ES are influenced by the stage of urban development and government policies. This study aims to assess the quantity and equity of ES under different scenarios in cites of China and Europe. Firstly, we used the Conversion of Land Use and its Effects at Small regional extent (CLUE-S) model to simulate future land cover under three scenarios: business-as-usual (BAU), a market-liberal scenario (MLS), and an ecological protection scenario (EPS). Then using ecosystem service model approaches and the landscape analysis, the dynamics of green infrastructure (GI) fraction and connectivity, carbon sequestration, and PM2.5 removal were further evaluated. The results show that: (1) over the past 20 years, Chinese cities have experienced dramatic changes in land cover and ES relative to European cities. (2) Two metropolises in China, Shanghai and Beijing have experienced an increase in the fraction and connectivity of GI and ES in the long-term built-up areas between 2010 and 2020. (3) EPS scenarios are not only effective in increasing the quantity of ES but also in improving the equity of ES distribution. The proposed framework as well as the results may provide important guidance for future urban planning and sustainable city development.

“…Within greenspace research, there has been much focus on the size or area of greenspace in cities [25]. While there is now increasing recognition that the location of greenspace is also important [26,27], so far little attention has been paid to the scales at which different pressures operate and different benefits operate for beneficiaries in urban settings. Spatial context is important and requires an understanding of both the nature and scale of the pressure (air pollution, flooding), as well as the scale and reach of the NBS that might be used to mitigate that pressure [28].…”
