Better Drainage in the Fight Against Floods

In Kuching, outdated drainage infrastructure and rapid urbanisation have exacerbated flash flooding, leaving residents vulnerable and frequently facing severe property damage and safety risks. Persistent heavy rainfall, worsened by climate change, causes rivers to swell and drains to overflow, inundating homes, cars, and streets. For locals living there, flooding is a recurring crisis, disrupting lives, destroying belongings, and even bringing wildlife hazards into urban areas. While government efforts are underway to improve drainage systems, experts and flood management researchers urge a more comprehensive approach that includes sustainable urban planning, updated infrastructure, and accessible flood data to better prepare for the city’s evolving environmental challenges. All this and more are explored in Macaranga's latest article, Fighting Floods with Better Drainage in Kuching, and we discuss the research and findings on this with Liani MK, a contributing writer with Macaranga who wrote the piece, Wong Siew Lyn, Editor, Macaranga, and Dr Charles Bong, a hydrology and urban drainage management researcher, Universiti Malaysia Sarawak (UNIMAS).
