Lake Lanao, or Ranao, in Lanao del Sur, is a true global treasure that serves as the cultural, ecological, and economic heart of Mindanao. As one of the world’s ancient lakes, formed millions of years ago, it is the second largest in the Philippines and once hosted a unique array of endemic fish species.Its deep connection to the Maranao people, whose name means “People of the Lake,” is evident in their rich culture, legendary myths, and vibrant arts like the Okir carvings. Furthermore, the lake is critical to the region’s energy supply, as its outlet, the Agus River, powers most of Mindanao’s hydroelectric plants. While this utility is essential, it also raises important debates about balancing critical national power needs with the urgent need to protect the lake’s sensitive ecosystem and the ancestral way of life of the Maranao people.

As Mindanao moves forward, the fate of Lake Lanao remains a vital measure of progress. The cumulative effects of development, pollution, and the pressures of resource management threaten the lake’s fragile biodiversity and the Maranao way of life. Recognizing Ranao’s status as both an ancient ecological marvel and a cultural sanctuary is the first step toward effective conservation. It is incumbent upon all of us: the government, private sector, and local communities, to collaborate on sustainable solutions that ensure this magnificent body of water can continue to sustain life, power the region, and inspire future generations of the “People of the Lake
