Para±aque: 2nd District Rep. Brian Raymund Yamsuan has called for the swift passage of a measure that would implement science-based strategies to lessen the effects of natural disasters and reduce losses. House Bill 4035, also known as the proposed Multi-Hazard Mapping Act, aims to formalize the creation and regular updating of hazard maps for every city and municipality, integrating these tools into disaster risk reduction efforts and local development planning.

According to Philippines News Agency, the proposed measure seeks to expand on the advancements made by the Project Nationwide Operational Assessment of Hazards (NOAH), which employed LiDAR (Light Detection and Ranging) scanning to identify risks and danger zones and create 3-D models to predict flooding and identify flood paths. The bill would mobilize cabinet-level agencies, led by the Department of Environment and Natural Resources, to produce, maintain, and update the hazard maps in coordination with local government units (LGUs).

Yamsuan emphasized the urgency of the bill, citing the recent destruction caused by typhoons Uwan and Tino, as well as strong earthquakes that hit the Visayas and Mindanao regions. These disasters have overwhelmed frontline responders and strained government resources, highlighting the necessity for better planning and preparedness.

Yamsuan stated that the increasing intensity and frequency of calamities require investment in a unified, comprehensive, science-based disaster risk reduction strategy. Such measures include the production and regular updating of hazard maps using the latest technologies, along with infrastructure and nature-based solutions to disaster risk reduction.

The multi-hazard maps would be integrated into the local development and disaster planning of each LGU, while national agencies would use the maps in the planning, design, and approval of public works and utilities. Yamsuan noted that better planning through the use of regularly updated hazard maps and risk assessment tools would guide the government in deciding on infrastructure projects, the safe construction of housing and evacuation centers, and the implementation of nature-based solutions like mangrove planting and soil erosion control to protect communities and save lives.
