Introduction

Implementing nature-based solutions (NbS) for urban water treatment offers valuable ecosystem services and societal benefits. Success relies on diverse technical and societal factors. This book offers guidelines for NbS implementation in South/Southeast Asian cities, covering constructed wetlands, green roofs, and floating treatment wetlands. Drawing from experiences in three countries, it provides detailed steps on planning, socio-economic evaluations, construction methods and costs, maintenance, and operational monitoring parameters. The book also explores approaches for scaling NbS in local contexts.
