Introduction

Stormwater runoff is a significant environmental challenge in urban areas, contributing to water pollution, flooding, and habitat degradation. Traditional stormwater management approaches, such as concrete channels and underground pipes, often exacerbate these problems by rapidly conveying runoff downstream. Green Infrastructure (GI) offers a more sustainable and ecologically sound alternative by mimicking natural hydrological processes to manage stormwater at its source. GI techniques, such as bioretention, green roofs, and permeable pavements, can effectively reduce runoff volume, improve water quality, and enhance urban aesthetics. This training course provides participants with the knowledge and skills to design, implement, and maintain GI systems for effective stormwater management. The course will cover hydrological principles, pollutant removal mechanisms, and the integration of GI into urban planning and development. By the end of the course, participants will be equipped to promote and implement GI solutions in their respective organizations and communities, contributing to more sustainable and resilient urban environments.
