THE recent flash flooding incident in Putrajaya highlights the urgent need to enhance flood mitigation measures and urban infrastructure against climate-induced challenges, said the Consumers’ Association of Penang (CAP).
The incident, caused by an hour of heavy rain led to water rising in Sungai Anak Gajah, and left 20 vehicles submerged.
CAP president, Mohideen Abdul Kader said despite Putrajaya’s reputation as a meticulously planned city with extensive green spaces and a systematic drainage system, the downpour led to severe flooding.
"This raises critical questions about the adequacy of current urban planning and infrastructure to handle extreme weather," he said.
Recent data from the Malaysian Meteorological Department indicates that rainfall intensity has surged by 40% over the past five years due to global warming and climate change.
Rising sea temperatures accelerate evaporation, leading to intense, short-duration rainfall with devastating consequences for urban areas.
"However, heavy rainfall is not the sole contributor to urban flash floods," said Mohideen.
Other contributing factors, he said include uncontrolled urbanisation, waste management issues, ageing infrastructure, deforestation and vegetation loss; and loss of natural waterways.
"Putrajaya, with its significant green infrastructure, such as the 600-hectare man-made Putrajaya Lake, should serve as a model for balancing development and environmental sustainability.
"However, urban sprawl and inadequate waste management have strained these systems, leaving the city increasingly vulnerable," added Mohideen.
He said CAP urges immediate action from all stakeholders, including local authorities, urban planners and the public to address the root causes of flash floods. A holistic approach is crucial:
He said a holistic approach is crucial.
"The National Green Technology Policy (2009) provides a foundation, but its implementation must expand to encompass more urban areas and address the challenges presented by urbanisation and climate change.
"Flash floods are no longer isolated incidents but warnings of a changing climate that we can no longer ignore.
"Decisive action is imperative to prevent further damage. Collaborative efforts between the government, private sector and communities are essential to building resilient cities capable of withstanding the effects of climate change," he added. - December 27, 32024
