Joffter of TWENTIETH CONGRESS OF THE ) REPUBLIC OF THE PHILIPPINES ) First Regular Session ) 25 AUG -5 P3:45 SENATE RECODE S. No. _ Introduced by Senator Jinggoy Ejercito Estrada AN ACT PROVIDING FOR THE ISSUANCE OF A LIST OF LOW-LYING AREAS OF THE PHILIPPINE TERRITORY VULNERABLE TO RISING SEA LEVELS AS A RESULT OF CLIMATE CHANGE, AND AREAS AT HIGH RISK FOR NATURAL DISASTERS, MANDATING THE DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES, DEPARTMENT OF SCIENCE AND TECHNOLOGY, PHILIPPINE SPACE AGENCY, CLIMATE CHANGE COMMISSION AND OTHER CONCERNED GOVERNMENT AGENCIES FOR ITS REGULAR UPDATING AND APPROPRIATING FUNDS THEREFOR AND FOR OTHER PURPOSES EXPLANATORY NOTE The Philippines, being one of the most disaster-prone countries in the world, faces multiple hazards that pose significant threats to lives, properties, and livelihoods. Our geographical location makes us particularly vulnerable to various natural disasters, including typhoons, earthquakes, volcanic eruptions, and the growing challenges posed by climate change. The devastating impact of natural disasters in recent years underscores the urgent need for a more systematic and scientific approach to disaster risk reduction and management. In November 2024, the Philippines witnessed an unprecedented occurrence when four tropical cyclones were simultaneously active in the Western Pacific - a phenomenon not seen since 1951. The combined effects of Tropical Storm Trami (Kristine) and Typhoon Kong-rey (Leon) alone resulted in damages exceeding P14 billion in agriculture and infrastructure.

Beyond the immediate threats of extreme weather events, our nation faces the long-term challenges of climate change. The Intergovernmental Panel on Climate Change (IPCC) reports that sea levels in our region are rising faster than the global average. This poses a direct threat to our coastal communities, where millions of Filipino fisherfolk reside and depend on maritime resources for their livelihood. The proposed National Hazard Mapping Act seeks to address these challenges by mandating the creation and regular updating of a comprehensive National Disaster Map. This initiative will identify low-lying areas vulnerable to rising sea levels and regions at high risk for natural disasters. The map will serve as a crucial tool for disaster preparedness, providing proper identification of lands bordering sea levels, areas exposed to volcanic eruption, and regions lying on earthquake faults. Notably, this legislation emphasizes a holistic approach by incorporating both scientific data and indigenous knowledge in hazard mapping. It also ensures the accessibility of these maps to local government units and communities through comprehensive training programs and information campaigns. The creation of this national disaster map will enable our local government units and communities to better prepare for and respond to natural disasters. By providing clear identification of high-risk areas and established evacuation routes, we can significantly reduce the loss of lives and properties during calamities. In view of the foregoing, immediate passage of this bill is earnestly sought. JINGGOY EJERCITO ESTRADA
