Typhoon Tino and Super Typhoon Uwan left devastation across the Philippines. In Cebu, P26.7 billion spent on flood control couldn’t prevent 158 deaths, while Negros Occidental saw agricultural losses exceeding P35 million. Beyond the tragedy, these disasters have reignited debates on ineffective infrastructure and sparked renewed interest in nature-based solutions (NbS) as a smarter way to protect communities.
What Are Nature-Based Solutions?
Nature-based solutions are interventions that work with ecosystems to address societal challenges while benefiting people and the environment. According to the International Union for Conservation of Nature (IUCN), NbS involve protecting, managing, or restoring ecosystems to solve problems like floods, soil erosion, or climate impacts.
Atty. Alaya de Leon of Forest Foundation Philippines explains that effective NbS must occur within ecosystems, tackle a clear societal challenge, and provide measurable benefits for both humans and biodiversity. NbS isn’t limited to forests or rural areas, it can thrive in cities too. In Bangkok, Thailand, an old factory was transformed into Benjakiti Forest Park, which manages floodwater while providing green space for wildlife and people. “If designed well, NbS often solves multiple problems at once,” de Leon says.
Nature-Based Solutions in Action
The Philippines already has local examples. In San Carlos City, Negros Occidental, communities have planted trees along 10 hectares of riverbank easements along the Malogo River. The vegetation absorbs rainfall, prevents soil erosion, and strengthens riverbanks. Near farms, the Sicaba River project uses bioswales to store stormwater, doubling as irrigation.
De Leon stresses that NbS must be evidence-based and tailored to local conditions. Local knowledge, scientific assessment, and proper planning are essential for success.
Beyond Quick Fixes
NbS is not a silver bullet. Cebu’s floods show that some disasters exceed the capacity of any single project. De Leon stresses that NbS should complement broader strategies like early warning systems, rainfall modeling, and disaster planning.
Her message is clear: instead of relying first on concrete structures, policymakers should explore nature-based options that deliver multiple benefits for people and ecosystems. Thoughtfully designed NbS can reduce risk, enhance resilience, and create smarter, more sustainable solutions to the country’s growing climate challenges.
