Nature-based solutions, such as reviving blue-green infrastructure (BGI), for climate adaptation in cities have been gaining global attention. In the case of India, the rapid urbanization since the end of the twentieth century has exacerbated the impact of climate change at significant environmental, social, and economic costs. Coastal cities in India commonly face climate change related hazards of flooding, rise in sea level, and urban heat islands. This article has assessed the usefulness of scientific information and community knowledge in planning, reviving, and maintaining BGI to make it a successful climate adaptation practice in coastal cities. The existing waterways and water bodies in India's coastal cities are a network linked to the green infrastructure that has been altered by sprawling urbanization. In response to Sustainable Development Goals 11 and 13, the cities of Kochi and Chennai have begun a process of recovering their BGI for greater resilience. This research has detected a shift in the social and administrative perception of BGI as a valuable resource for climate adaptation in recent times. Actions in backwaters and canals, promoted by Chennai and Kochi municipal corporations, present new steps toward mainstreaming adaptation of BGI into the local regulatory framework.

用于城市气候适应的基于自然的解决方案，例如恢复蓝绿基础设施 (BGI)，已引起全球关注。就印度而言，二十世纪末以来的快速城市化加剧了气候变化的影响，造成了巨大的环境、社会和经济成本。印度的沿海城市通常面临与气候变化相关的洪水、海平面上升和城市热岛效应等危害。本文评估了科学信息和社区知识在规划、恢复和维护华大基因方面的有用性，使其成为沿海城市成功的气候适应实践。印度沿海城市现有的水道和水体是一个与绿色基础设施相连的网络，而绿色基础设施已被无序扩张的城市化所改变。为响应可持续发展目标 11 和 13，科钦市和金奈市已开始恢复其 BGI 以提高韧性。这项研究发现，近年来社会和行政部门对华大基因作为适应气候变化的宝贵资源的看法发生了转变。Chennai 和 Kochi 市政公司推动的死水和运河行动为将 BGI 的适应纳入当地监管框架提出了新的步骤。
