Obtaining public and/or private finance for upscaling urban nature-based solutions (NBS) is a key barrier for reaching urban sustainability goals, including climate mitigation and adaptation. We carry out a systematic review of the academic literature to understand the key barriers and corresponding strategies for financing urban NBS. First, we report on specific financing challenges and strategies found for NBS uptake in four urban ecological domains: buildings, facades and roofs; urban green space (parks, trees); allotment gardens (including urban agriculture); and green-blue infrastructure. Across domains, we identify two overarching barriers of NBS finance: (1) coordination between private and public financiers and (2) integration of NBS benefits into valuation and accounting methods. We discuss strategies found in the literature that address these barriers; here, two things stand out. One, there is a large variety of valuation strategies that does not yet allow for an integrated accounting and valuation framework for NBS. Two, strategies aimed at coordinating public/private finance generally look for ways to encourage specific actors (real estate developers, residents) that benefit privately from an NBS to provide co-financing. We visualize our findings into a framework for enabling (public and/or private) finance for upscaling urban NBS.

审查基于城市自然的解决方案的融资障碍和策略

获得公共和/或私人资金以升级基于城市自然的解决方案(NBS)是实现包括气候减缓和适应在内的城市可持续性目标的主要障碍。我们对学术文献进行系统的回顾,以了解为城市国家统计局筹集资金的主要障碍和相应策略。首先,我们报告了在四个城市生态领域(建筑物,立面和屋顶)中针对国家统计局采用的特定融资挑战和策略。城市绿地(公园,树木);分配花园(包括都市农业);和蓝绿色的基础设施。在各个领域中,我们确定了国家统计局财务的两个主要障碍:(1)私人和公共金融机构之间的协调;(2)将国家统计局的利益整合到评估和会计方法中。我们讨论了文献中发现的解决这些障碍的策略。在这里,两件事脱颖而出。第一,目前存在多种评估策略,尚无法为国家统计局建立一个综合的会计和评估框架。第二,旨在协调公共/私人融资的策略通常寻找鼓励特定行为者(房地产开发商,居民)的方法,这些特定行为者从国家统计局私人受益,以提供共同筹资。我们将我们的发现可视化为一个框架,以使(公共和/或私人)融资能够扩大城市国家统计局的规模。旨在协调公共/私人融资的战略通常寻找鼓励特定行为者(房地产开发商,居民)的方法,这些特定行为者从国家统计局私人受益,以提供共同筹资。我们将我们的发现可视化为一个框架,以使(公共和/或私人)融资能够扩大城市国家统计局的规模。旨在协调公共/私人融资的战略通常寻找鼓励特定行为者(房地产开发商,居民)的方法,这些特定行为者从国家统计局私人受益,以提供共同筹资。我们将我们的发现可视化为一个框架,以使(公共和/或私人)融资能够扩大城市国家统计局的规模。
