Scaled up planning and implementation of nature-based solutions requires better understanding of broad characteristics (typologies) of the current governance and financing landscape, collaborative approaches amidst local complexities, and factors of scalability. An inventory was compiled of water-related ecological infrastructure intervention projects in two river systems in South Africa, incorporating actor, environmental, social, and financial dimensions and benefits. Qualitative participatory analysis revealed eight typologies. Post-hoc classification analysis determined similarities and/or unique characteristics of seven quantitative typologies. Key characterising factors included the complexity/size of financial flows, complexity of partnership/governance arrangements, mandates/goals of actors, type of ecological infrastructure, trade-offs in investment in ecological/built infrastructure, and the model used for social benefits. Identified scalable typologies offer structures suited to increased investment, with other typologies offering specialised local value. A range of ecological infrastructure intervention typologies with differing biophysical and socioeconomic outcomes provide choices for investors with specific goals, and benefits to landscape actors.

扩大基于自然的解决方案的规划和实施需要更好地了解当前治理和融资环境的广泛特征（类型）、当地复杂性中的协作方法以及可扩展性因素。编制了南非两个河流系统中与水相关的生态基础设施干预项目的清单，其中包括参与者、环境、社会和财务方面和利益。定性参与分析揭示了八种类型。事后分类分析确定了七种定量类型的相似性和/或独特性。关键特征因素包括资金流动的复杂性/规模、伙伴关系/治理安排的复杂性、参与者的任务/目标、生态基础设施的类型、生态/已建成基础设施投资的权衡取舍，以及用于社会效益的模型。确定的可扩展类型提供适合增加投资的结构，而其他类型提供专门的本地价值。一系列具有不同生物物理和社会经济结果的生态基础设施干预类型为具有特定目标的投资者提供选择，并为景观参与者带来好处。
