Pinya Festival: A Celebration of Calauan’s Pineapple Heritage
Every 15th of May, the town of Calauan, Laguna comes alive with vibrant colors and jubilant celebrations during the annual Pinya Festival. This event, which
Laguna Lake, the largest lake in the Philippines, is more than just a vast expanse of water. It’s a lifeline, a cultural icon, and in many ways, a reflection of the region’s complex relationship with nature and progress. Located southeast of Metro Manila, this freshwater lake stretches across approximately 911 to 949 square kilometers, making it the country’s largest inland body of water. It borders the provinces of Laguna to the south and Rizal to the north, creating a wide crescent-shaped basin that has shaped the life and livelihood of millions.
The lake is fed by more than a hundred rivers and streams, with twenty-one major tributaries contributing to its volume. Among these, the Pagsanjan River plays a crucial role, accounting for around 35% of the lake’s inflow. Its only natural outlet is the Pasig River, which flows westward toward Manila Bay. This unique hydrological system not only regulates water levels in the region but also plays a critical role in flood control and freshwater distribution.
Beyond its geographic and environmental functions, Laguna Lake has long served as a cradle of livelihood for the people who live around it. It supports a thriving aquaculture industry, providing freshwater fish that help feed communities in Laguna and nearby provinces. The lake also sustains agriculture, supports small-scale industries, and even contributes to power generation. For many locals, it is quite literally where life begins and continues. Households depend on its waters for domestic needs, and businesses tap into it for operations, making it integral not just to survival but to economic activity as well.
But all of this has come at a cost. Over the years, Laguna Lake has suffered from extensive environmental degradation. Pollution remains its most pressing issue. Untreated sewage, household waste, industrial runoff, and agricultural chemicals are routinely dumped into the lake. The lack of proper waste treatment infrastructure in many lakeside communities only makes things worse. You also have eutrophication—when excessive nutrients like nitrogen and phosphorus trigger the growth of algae. These algal blooms might look harmless at first, but they suffocate aquatic life by depleting oxygen in the water, turning vibrant ecosystems into dead zones.
Then there’s the issue of overfishing. For years, the lake has been fished intensively—sometimes using illegal and harmful methods—which has put significant pressure on fish populations. Communities that once depended on steady catches now face dwindling returns, and with that comes food insecurity and rising tensions over access to resources. This ecological imbalance is a clear sign that the lake is reaching a breaking point.
Efforts to manage and rehabilitate the lake fall under the jurisdiction of the Laguna Lake Development Authority, or LLDA. Established through Republic Act No. 4850, the LLDA was tasked with overseeing the sustainable development of the Laguna Lake region. It implements zoning policies, monitors water quality, and enforces environmental regulations. One of its more innovative programs is the Environmental User Fee System, which charges companies based on the volume and toxicity of their wastewater discharges—a first of its kind in Southeast Asia. Still, regulation alone isn’t enough. Enforcement remains a challenge, especially with overlapping jurisdictions and inconsistent political will.
What’s clear is that government action needs to be matched by grassroots involvement. Protecting Laguna de Bay is not a one-agency task. Local communities, civil society groups, fisherfolk, and even the private sector all have a role to play. Some are already stepping up. Community-led cleanups, shoreline planting, public awareness drives, and sustainable fishing initiatives are gaining momentum. The idea is simple: if the lake is to survive, everyone must be part of the solution. As one local environmental officer put it, “we need a whole-of-community approach.”

Laguna de Bay is not just part of the landscape of Laguna—it is central to its identity. It nurtures people, supports economies, and sustains biodiversity. But it is also in danger. The threats it faces are not new, and neither are the solutions. What’s needed now is consistency, collaboration, and the collective will to care for it—not tomorrow, not next year, but today. Because how we treat Laguna de Bay is ultimately a reflection of how we treat ourselves, our communities, and the generations that follow.
