A holistic framework for assessing co-benefits of street-scale green infrastructure interventions

一个全面的框架，以评估共同利益的街道规模的绿色基础设施干预核心城市地区往往bemade的街道峡谷，是其中污染最严重的城市环境，由于有限的分散交通排放的周围建筑物。在城市地区使用绿色基础设施（GI），如路边树篱、树木和绿墙/屋顶，可以帮助减少交通排放，并提供许多其他共同效益，包括改善热量、减少噪音和增加生物多样性。然而，所有这些好处都对当地环境非常敏感，计划不周的GI可能会使情况恶化或实现有限的共同利益。因此，本项目将使用实验，建模和文献综述的组合来解决以下问题：污染减排和GI提供的其他共同利益（冷却，噪音缓解和生物多样性）之间的权衡是什么？在不同的尺度上（街道尺度到城市尺度）是否有不同的权衡？这些权衡是完全特定于上下文的，还是可以推导出可概括的关系，以帮助规划者最好地利用地理标志？通过对上述问题的回答产生的所有知识将用于开发一个易于使用的基于证据的评估框架，该框架有助于为小规模GI特征规划多种共同利益，考虑当地情况，这在城市地区规划中非常需要。

A holistic framework for assessing co-benefits of street-scale green infrastructure interventions Core urban areas tend to bemade up of street canyons and are among the most polluted urban environments due to the restricted dispersion of trafficemissions by the surrounding buildings. The use of green infrastructure (GI) such as roadside hedges, trees, and greenwalls/roofs in urban areas can help to abate the exposure to traffic emissions and also offer many other co-benefitsincluding heat amelioration, noise reduction and increased biodiversity. However, all these benefits are very sensitive to thelocal context, and poorly planned GI can worsen situations or achieve limited co-benefits. Therefore, this project will use acombination of experiments, modelling and literature review to address the following questions: What are the trade-offsbetween pollution abatement and other co-benefits provided by GI (cooling, noise mitigation and biodiversity)? Arethere different trade-offs at different scales (street scale to city scale)?... Are these trade-offs completely context-specific,or can generalisable relationships be derived to help planners make the best use of GI? All the knowledge generatedthrough the answers to the above questions will be used to develop an easy to use evidence-based assessmentframework that helps to plan multiple co-benefits for small scale GI features, accounting for local contexts, which is sorelyneeded in urban area planning.
