CITY OF SAN FERNANDO, Pampanga — The Department of Environment and Natural Resources (DENR) is ramping up its high-tech monitoring in Central Luzon to prepare communities for the impact of El Niño, using Automated Weather Stations (AWS), satellite mapping, and GIS-based risk modeling.
DENR Secretary Juan Miguel Cuna said the agency is shifting from reactive to precision early warning to protect forests, water resources, and coral reefs.
“In an era of accelerating climate extremes, timely information saves ecosystems and lives,” Cuna said.
Eye on Central Luzon’s Coasts and Forests
In Central Luzon, the DENR has intensified monitoring in the coastal provinces of Aurora, Bataan, and Zambales, where rising sea surface temperatures have triggered coral bleaching concerns.
In Aurora province, satellite-derived heat stress tracking prompted coral bleaching alerts in May, June and July 2026, with waters reaching Coral Bleaching Alert Level 1. Marine monitoring teams in Masinloc and Oyon Bay Protected Landscape and Seascape in Zambales have been ordered to submit weekly reef assessments using GIS-based mapping.
The technology, using data from the US National Oceanic and Atmospheric Administration (NOAA), helps detect when stressed corals expel algae and turn white — a sign of vulnerability to starvation.
On land, field data is also being used to track rainfall deficits, drying creeks, dry forest patches, and peatland fire risks to guide water conservation efforts and direct forest patrols to vulnerable areas.
“We are equipping our field teams and local chief executives with real-time environmental intelligence to safeguard our forests, coral reefs, water resources, and coastal communities before severe damage occurs,” Cuna stressed.
The DENR has directed all regional offices in Central Luzon to maintain continuous data transmission from weather stations and to promote water-efficient practices, monitor water availability, and prioritize areas at risk of shortages, dry spells, and drought.
The agency said the data-driven approach will help Central Luzon communities better prepare for drought, water scarcity, and climate adaptation in the coming months.
