In Latin America and the Caribbean, river restoration projects are increasing, but many lack strategic planning and monitoring. We tested the applicability of a rapid visual social-ecological stream assessment method for restoration planning, complemented by a citizen survey on perceptions and uses of blue and green infrastructure. We applied the method at three urban streams in Jarabacoa (Dominican Republic) to identify and prioritize preferred areas for nature-based solutions. The method provides spatially explicit information for strategic river restoration planning, and its efficiency makes it suitable for use in data-poor contexts. It identifies well-preserved, moderately altered, and critically impaired areas regarding their hydromorphological and socio-cultural conditions, as well as demands on green and blue infrastructure. The transferability of the method can be improved by defining reference states for assessing the hydromorphology of tropical rivers, refining socio-cultural parameters to better address river services and widespread urban challenges, and balancing trade-offs between ecological and social restoration goals.
在拉丁美洲和加勒比地区,河流修复项目不断增加,但许多项目缺乏战略规划和监测。我们测试了一种快速直观的社会生态溪流评估方法在修复规划中的适用性,并辅以一项关于公民对蓝色和绿色基础设施的认知与使用情况的调查。我们在(多米尼加共和国)哈拉巴科阿的三条城市溪流中应用了该方法,以确定基于自然的解决方案的优先选择区域并进行排序。该方法为战略性河流修复规划提供了空间明确的信息,其高效性使其适用于数据匮乏的情况。它能识别出在水文形态和社会文化条件以及对绿色和蓝色基础设施的需求方面保存完好、适度改变和严重受损的区域。通过定义用于评估热带河流水文形态的参考状态、完善社会文化参数以更好地应对河流服务和普遍存在的城市挑战,以及平衡生态和社会修复目标之间的权衡,可以提高该方法的可转移性。
