Abstract

Market-based instruments, including competitive tenders, are central to funding global environmental restoration and management projects. Recently, tenders have been utilised to fund Nature-based Solutions schemes for Natural Flood Management, with the explicit purpose of achieving co-benefits; flood management and reducing inequities. While multiple studies consider the efficacy of Nature-based Solutions for tackling inequities, no prior research has quantified whether the resource allocation for these projects has been conducted equitably. We analyse two national natural flood management programmes funded through competitive tenders in England to explore who benefits by considering the characteristics of projects, including socio-economic, geographical (e.g. rurality) and flood risk dynamics. Our results suggest that inequity occurs at both the application and funding stages of Nature-based Solutions projects for flood risk management. This reflects wider international challenges of using market-based instruments for environmental resource allocation. Competitive tenders have the potential to undermine the equitable benefits of Nature-based Solutions.

以市场为基础的工具为洪水风险管理的基于自然的解决方案提供资金,可以极大地惠及富裕地区。
以市场为基础的手段,包括竞争性招标,是为全球环境恢复和管理项目提供资金的核心。最近,政府以招标方式资助以自然为本的自然洪水管理方案,目的明确为取得共同利益;洪水管理和减少不平等。虽然多项研究考虑了基于自然的解决方案在解决不平等问题方面的有效性,但之前没有研究量化这些项目的资源分配是否公平。我们分析了英国通过竞争性招标资助的两个国家自然洪水管理项目,通过考虑项目的特点,包括社会经济、地理(如农村)和洪水风险动态,来探索谁受益。我们的研究结果表明,基于自然的解决方案项目在洪水风险管理的应用和资助阶段都存在不平等。这反映了利用基于市场的工具进行环境资源配置所面临的更广泛的国际挑战。竞争性招标有可能破坏基于自然的解决方案的公平效益。
