Assessing the causes of flooding should be rooted in science-based analysis, particularly in light of changing weather patterns influenced by climate change, according to the Department of Environment and Natural Resources (DENR).
The DENR cited meteorological data from the past decade, which shows a significant increase in rainfall volume attributed to climate change, according to the state weather bureau PAGASA.
This noticeable shift in weather patterns has worsened challenges faced by urban areas like Metro Manila, where heavy rainfall can overwhelm drainage systems and lead to substantial flooding, the department said.
The DENR urged local government units (LGUs) to take proactive measures in addressing flood risks. It stressed the importance of LGUs integrating comprehensive flood risk reduction programs into their design and solid waste management plans to better protect communities from the adverse effects of increased rainfall.
It said among the strategies LGUs can undertake include improved drainage designs capable of handling increased rainfall volumes; solid waste management enhancement to prevent blockages in drainage systems; community engagement to raise awareness and promote resilience; and ecosystem restoration which involves implementing green infrastructure and restoring natural water systems to absorb excess rainwater.
The DENR also stressed the importance of adapting urban planning strategies to safeguard communities. The department also reiterated its commitment to working with LGUs and the public to create a future that mitigates flooding risks and enhances overall community resilience.
