CAN WE GENERATE POWER WHILE CONTROLLING FLOODS?

CAN WE GENERATE POWER WHILE CONTROLLING FLOODS?

Yes, we can—and the truth is, we already do. The Philippines has long had the capability to generate power while controlling floods, and in some cases, we even get irrigation as a bonus. As I like to say, anywhere we have water, we can also grow fish, so why not add aquaculture to the benefits as well? That makes it a four-in-one solution: power generation, flood control, irrigation, and aquaculture. So why aren’t we building more of these?

Let’s start with our oldest model: Caliraya-Kalayaan, one of Southeast Asia’s first pumped-storage hydropower systems. Built decades ago, it is still producing nearly 797 megawatts of clean power—enough for almost three million households. But its benefits go beyond electricity. Caliraya moderates water flow during typhoons, complements irrigation systems downstream, and has even become a tourism zone. It is everything we want infrastructure to be: efficient, multi-purpose, and future-proof.

Fast forward to today, and we now have a second working model: Lake Mainit Hydroelectric Power Plant in Jabonga, Agusan del Norte. At 24.9 MW, it is smaller, but its impact is huge. Jabonga used to suffer devastating floods from Lake Mainit overflow. Today, controlled water releases help protect the town—while generating clean energy for the Mindanao grid. This is real-world climate resilience, not theoretical talk.

But here is the question that keeps bothering me: Why did it take us several decades to move from Caliraya to Jabonga? And more importantly: how soon can we bring this model to Lake Lanao, Pantabangan, Magat, Naujan Lake, or any of our country’s 200+ lakes?

To build these four-in-one systems, we need inter-agency cooperation. The Department of Public Works and Highways (DPWH) could take the lead on flood control. The National Irrigation Administration (NIA) should handle irrigation. The National Electrification Administration (NEA) and the Department of Energy (DOE) can take care of power. The Department of Agriculture (DA) can integrate aquaculture. But who will convene them? How do we break the silos?

Perhaps we need a National Water-Energy Council to push these projects faster. President Marcos Jr. has already emphasized the need for more dams and integrated water management. There is even a proposal to merge DOE and NIA for better coordination. But coordination only matters if it speeds things up—not slows things down with bureaucracy.

And while we build these mega-systems, let us not forget the opportunities at the local level. LGUs can develop retention ponds with micro-hydro turbines. Barangays can set up aquaponics linked to flood buffers. Upland areas could use small-scale hydropower to electrify remote villages while reducing downstream floods.

The truth is simple: water is power, and water is also livelihood. Every time we capture it, we reduce disaster. Every time we release it through turbines, we generate electricity. Every time we store it, we irrigate farms. And every time we keep it clean, we can raise fish.

So yes, the answer is clear.
We can generate power while controlling floods—and while irrigating farms and growing fish.
We have done it before; we are doing it now; and we can do it everywhere.

The only real question is:
When will we start treating water as the multi-purpose national asset it truly is?

REGROWING FORESTS AND REVIVING WILDLIFE

REGROWING FORESTS AND REVIVING WILDLIFE

The Philippines is actively regrowing forests and reviving wildlife through new reforestation campaigns and upgraded forest policies. That much is clear. What is not clear is whether the agencies in charge of these programs are actually talking to each other.

On one hand, we have the Forest Management Bureau (FMB) of the DENR, mandated to regrow forests—through the National Greening Program, Forest Land Use Plans, and the new “Forests for Life” initiative aiming to plant millions of trees by 2028. On the other hand, we have the Biodiversity Management Bureau (BMB), which is in charge of wildlife conservation and protected areas.

But here is my question: Are FMB and BMB talking to each other? Really talking to each other?

Because we all know one basic ecological truth: when certain trees come back, certain wildlife come back. The two are inseparable. Wildlife do not survive in PowerPoint presentations or policy memos. They survive in habitats. They live in trees. They eat the fruits. They hunt in forest canopies. And if the wrong trees are planted—or if monocultures replace diverse forests—we should not expect wildlife revival to happen automatically.

Let’s take one of our most iconic species: the Philippine eagle. It does not nest in just any random tree planted under a reforestation banner. It needs primary dipterocarp forests—the towering lauan, apitong, and bagtikan species that form dense, old-growth canopies. Without these trees, the eagle has nowhere to live, hunt, or reproduce. No amount of ceremonial tree planting can change that.

Mangroves are another obvious example. When mangrove trees return, fish, crabs, shrimp, and marine life return almost immediately. Nature knows what to do—if we plant the right species in the right place.

So why don’t we have a matching database—a national ecological matrix that tells us which trees support which species? Which reforestation areas can restore which wildlife? Which sites can be optimized for biodiversity, not just for photo ops?

Who in the government is responsible for compiling this list? Should this be a joint project of FMB and BMB? Should DENR tap PhilSA, NAMRIA, and even NASA or USGS datasets to build a nationwide ecological restoration map? We have more digital tools today than at any point in our history. So why are we not using them?

Another issue is greenwashing—the practice of making a project look “environmental” even when its actual impact is questionable. Planting millions of seedlings is meaningless if they are monocultures, if they die after one dry season, or if they are planted in the wrong ecosystem. Real forests are not linear rows of seedlings; they are complex, diverse, living systems.

We also cannot forget Indigenous communities—some of the best forest stewards in the country. Many of the areas targeted for restoration or new tenure contracts overlap with ancestral domains. Any national reforestation policy that ignores Indigenous rights risks repeating old mistakes.

Still, I believe this moment offers an opportunity. The DENR is opening more than a million hectares for restoration and conservation investments. The FAO is supporting forest and landscape restoration programs. Local communities and barangays can now be partners in wildlife revival, not passive beneficiaries.

If the Philippines wants to revive both forests and wildlife, the solution is simple but long overdue: plant the right trees, in the right places, for the right species—then monitor it with real science, not slogans.

The forest will take care of the wildlife, and the wildlife will take care of the forest. But only if our agencies take care of the data, and take care of each other.

DEBT FOR NATURE SWAPS ARE STILL UP FOR GRABS

 DEBT FOR NATURE SWAPS ARE STILL UP FOR GRABS

According to official statements, the Philippines is still actively involved in “Debt for Nature Swap” (DfNS) programs. I am not questioning that. What I am questioning is the silence that surrounds it. Why is there so little information coming out about what the government is doing, how far it has gone, and whether we are actually meeting our conservation or climate targets?

A DfNS is a simple concept: part of our foreign debt is forgiven, but in exchange we commit to protecting forests, marine areas, biodiversity, or climate-related assets. The mechanism is not new; what’s new is the renewed global push. As of 2025, over a dozen countries have signed fresh swaps—El Salvador closed a record-breaking US$1 billion river-conservation deal last year, while the global Debt-for-Nature Coalition has already facilitated roughly US$1.4 billion in conversions covering some 3 million square kilometers of ecosystems. Clearly, the world is moving.

But are we?

For the Philippines to succeed in DfNS programs, we need something very basic: an inventory of natural assets that are actually “swappable.” What are these assets? If these are forests, where exactly are they? What tree species are planted? What is their health status? Have these forests already matured enough to prevent landslides, flooding, or soil erosion—because that is what they are supposed to do?

Can we see these forests and protected areas on a map—an actual geographic map, not just policy documents with bullet points?

This leads me to my next question: if DfNS projects are being implemented, why are their sites not visible, identifiable, locatable? In 2025, mapping is not a luxury—it’s a minimum requirement for credibility. The National Mapping and Resource Information Authority (NAMRIA) already has satellite-derived land cover maps. PHIVOLCS has hazard maps. PhilSA (our space agency) now has imaging capabilities. Combine these three datasets and we would already have a working geospatial baseline for DfNS and carbon credit projects.

Add to that the publicly accessible data from NASA, USGS, JICA, and Google Earth Engine, and we could have the most complete environmental monitoring map this country has ever produced.

Yet, where is it?

Let me raise another point: DfNS and carbon credit schemes should go hand in hand. One protects nature; the other monetizes conservation. Forests, mangroves, peatlands, and seagrass beds are not just “nice to have”—they absorb carbon, reduce disaster risks, and can be translated into carbon credits. So where are these carbon credit projects? Are these simply tree planting programs? Does the National Greening Program (NGP) form part of a larger carbon strategy or is it still trapped in the annual cycle of planting without long-term verification?

As the Department of Finance continues discussions with the U.S. Treasury on new debt-for-nature and debt-for-climate swaps, we must be ready with verifiable, measurable, and mappable natural assets. Otherwise, we risk offering commitments we cannot quantify—much less prove.

And yes, I understand that DfNS programs require technical work, policy alignment, and international negotiations. But transparency is just as important. If the government wants public support for climate finance innovations, then it must show us the data, the maps, the numbers—and the forests.

Debt-for-nature swaps are still up for grabs. The question is whether the Philippines is ready to grab them.

WHO SHOULD OWN BURIED TREASURES FOUND?

 WHO SHOULD OWN BURIED TREASURES FOUND?

Well, it really depends on where it is found, and what exactly is found. That’s the simple answer. But as with all matters involving money, history, and the law, nothing is ever that simple.

For sure, anything with cultural, historical, archaeological, or anthropological value should belong to the national government. These are not ordinary objects—they are fragments of our collective identity. They are our national memory buried under soil, sand, and time. No private owner should have absolute claim over something that belongs to the Filipino story.

Everything else—ordinary gold bars, coins, jewelry—can be shared between the finder and the State, perhaps 50/50. But let’s be honest: if the government doesn’t know about the discovery, how can it even claim its share? This is where transparency and incentives matter.

But to me, what matters most are the finds that tell us who we are. These are far more precious than gold. And ironically, they’re also far more expensive to “buy back” once they end up in private hands. That’s why the better solution is for the government, particularly the National Museum of the Philippines (NMP), to be more directly involved—funding digs, monitoring sites, and responding quickly to discoveries.

Unfortunately, I also know how hard it is to squeeze budget allocations from Congress. Agriculture, infrastructure, healthcare, education, defense—these always come first. But what about national pride? What about identity? These are part of our social capital. You cannot assign a monetary value to them, but without them, a nation loses its soul.

And speaking of national pride, let’s compare ourselves with other countries.

Recently in France, a man found gold bars worth £616,000 in his garden. He did the right thing—he reported it. His reward? Most likely nothing. French law gives priority to the original owner or their heirs. And if there are no heirs, the treasure goes to the State. Imagine finding a fortune and walking away empty-handed just because you were honest.

In contrast, another couple in the U.K. found 70 Tudor-era gold coins while gardening. Those coins were sold for £467,000, and the finders received compensation under the U.K.’s Treasure Act. Their honesty was rewarded, not punished.

So where does the Philippines fall?

Our Civil Code (Articles 438–439) says hidden treasure belongs to the landowner—but if someone else finds it by chance, the split is 50/50. Simple enough.

But things change the moment the find has cultural or scientific value. Under the National Cultural Heritage Act (RA 10066), the State can claim such objects, with “just compensation.” The government may step in to preserve the site, the artifacts, and even the surrounding environment. And rightly so.

Should we tighten these laws further? Should LGUs craft their own reporting protocols? Should barangays participate in heritage conservation? Should the NMP finally get the budget it deserves?

To move forward as a nation, we must first understand our past. Somewhere beneath our fields, rivers, mountains—even backyards—are stories waiting to be discovered. But unless we protect them, someone else will own our history.

And what good is a nation that cannot even keep its own treasures?

COULD SEAWEEDS BE THE FUTURE OF PLASTIC?

 COULD SEAWEEDS BE THE FUTURE OF PLASTIC?

I am very fascinated by that question, for two very important reasons. First, what could this mean for the thousands of Filipino seaweed farmers who depend on this commodity for their livelihood? And second, what could this mean for our environment—now drowning in millions of pieces of plastic that pollute our lands, seas, and oceans every single day? Add to that the alarming truth that microplastics are already entering our bodies through the food chain. If there was ever a moment to rethink plastic, it’s now.

God has blessed our country with long coastlines and wide open seas. We are, in fact, one of the world’s top producers of seaweeds. So imagine for a moment if seaweeds could replace plastic. Imagine if something that has become a global burden—plastic—could be replaced by something that grows naturally, renewably, and abundantly right here in our coastal waters.

What has caused us problems all these decades could suddenly present us with an opportunity.

So what should we do next? Clearly, this is something that belongs in the portfolio of the Department of Science and Technology (DOST). But other agencies must also jump in. The DFA, if we need access to patents or licensing arrangements. The DTI, if we want investors or partnerships with companies already leading the technology. And how about the plastics industry—can they transition quickly into seaweed-based materials? And if the technology requires new skillsets, do we need to start producing new types of engineers?

At the production level, BFAR should help identify which species of seaweeds grow best for this purpose. Should we focus on kelp? Eucheuma? Gracilaria? Science must guide farming.

But the potential is certainly exciting.

Why Seaweed Could Be the Future of Plastic

Seaweed-based bioplastics are biodegradable, compostable, and non-toxic. They can break down naturally in soil or water, unlike petroleum-based plastics that persist for centuries. Seaweed grows extremely fast—some species up to one meter per day—and requires no fertilizers, no freshwater, and no land. It even absorbs carbon dioxide as it grows, giving it climate benefits on top of everything else.

Best of all, some seaweed bioplastics are edible. Imagine buying a drink in a sachet you can swallow. This is not science fiction—companies like Notpla and Sway are already doing it. There are seaweed-based films for food packaging, coatings for fast-food wrappers, molded containers, and even textile fibers under development.

Universities and innovation labs, such as Flinders University working with the biotech firm one • five, have developed sodium alginate coatings that can replace polyethylene in common wrappers. Beyond packaging, seaweed is also being explored for biofuels and sustainable fabrics.

But there are challenges. Right now, seaweed bioplastics remain more expensive than petroleum-based plastics. Scaling up farming must be done without harming marine ecosystems. And some products may lack the long-term durability needed for certain industrial uses.

Still, the opportunity is enormous.

For coastal countries like ours, seaweed represents a systems-level solution—a chance to strengthen livelihoods, reduce plastic pollution, and create a circular economy all at once. Imagine barangay-level seaweed farming cooperatives producing biodegradable packaging for local businesses. Imagine LGUs shifting their procurement to seaweed-based materials. Imagine our coastal communities becoming hubs of green manufacturing.

Could seaweeds be the future of plastic?
If we make the right decisions today, the answer could very well be yes.

HOW ABOUT TURNING HUMAN WASTE INTO RENEWABLE ENERGY?

 HOW ABOUT TURNING HUMAN WASTE INTO RENEWABLE ENERGY?

It may not be an appetizing idea, but who cares if it saves money and makes money? Who cares if it will lower our energy costs and thus reduce our dependence on imported fossil fuels? Who cares if it’s “dirty”—can black coal be any dirtier? The truth is, using human waste can generate clean energy — and that is what really matters.

Believe it or not, this isn’t a science-fiction fantasy. The technology is already working in many parts of the world. So why haven’t we embraced it here? More to the point: why don’t we do it as soon as possible?

---

Why It Makes Sense

The logic is simple: human waste is free, abundant, and renewable. Through processes like anaerobic digestion, microorganisms break down sewage sludge in the absence of oxygen, producing methane-rich biogas that can be used to generate electricity, heat, or even fuel. The leftover “digestate” can be used as fertilizer. 

There are other high-tech methods, too: hydrothermal carbonization can convert wet sewage into a coal-like “hydrochar,while promising lab-scale microbial fuel cells use bacteria to generate electricity directly from organic waste.

These waste-to-energy systems do more than just produce power. They also reduce greenhouse-gas emissions by capturing methane that would otherwise leak into the atmosphere. And for wastewater treatment plants, the energy recovered can offset a significant portion of their energy needs. One study estimates that anaerobic digestion could offset 50–60% of a plant’s electricity consumption. 

---

The Big Picture: It's Already Being Done

Globally, the potential is massive. If all sewage in the world were collected and treated through anaerobic digestion, we could generate 210–300 TWh of energy annually — enough to meet the electricity needs of tens of millions of people. The World Biogas Association estimates that by 2050, expanded sewage digestion could generate 385 TWh/year and reduce CO₂ emissions by 95 million tons. 

In Europe, it’s not just theory: Sweden and Poland have wastewater treatment plants that use biogas in real operations. In Barcelona, buses are already running on biomethane derived from human waste — the pilot project emits around 80% less CO₂ than natural gas. 

---

What About the Philippines?

Here at home, the picture is starting to take shape. The Department of Energy lists several biogas projects; for instance, FDR Integrated Resource Recovery in Naga City, Cebu, runs a 0.624 MW plant using municipal waste. A German company, Atmosfair, has also teamed up with Filipino firms to build biogas facilities that convert organic waste into energy. 

And while most of the local projects use animal or food waste, not human waste, the groundwork is promising. We already have sewage treatment infrastructure: take the Marikina North Sewage Treatment Plant in Metro Manila, which treats 100 million liters of used water daily. Why not tap that sludge for biogas?

---

But Why the Delay?

If this is such a “free” resource, why haven’t we done more? There are real challenges. Building and maintaining digesters or hydrothermal systems requires upfront investment. Even once made, you need steady waste input and skilled operators. 

Then there’s public perception. Many people recoil at the idea of “burning sewage,” even though coal plants are far dirtier. And from a policy standpoint, governments must create incentives, set safety standards, and ensure digestate is safe for reuse. The World Biogas Association highlights the need for clear regulations and quality benchmarks. 

---

So, What Should We Do?

1. Lead the Charge
   The DOE should take the lead — but they shouldn’t be alone. Bring in the DOST (Department of Science and Technology) for research, pilot funding, and technical validation.
   
   

2. Start Small but Smart
   Launch pilot biogas digesters at existing sewage treatment plants like Marikina, or new community systems in underserved areas. Prove the model, then scale up.
   
   

3. Engage Communities
   Educate the public about how “dirty” waste can become clean, renewable energy — and how it could lower electricity costs.
   
   

4. Integrate with Water Projects
   If biogas lowers power costs significantly, could this make desalination more affordable? Imagine turning saltwater to fresh water powered by waste-derived energy.
   
   

5. Set Clear Policy
   Create standards for digester safety, emissions, and the use of residuals. Provide subsidies or tax breaks for waste-to-energy projects to attract private investment.
   
   

---

Final Word: What’s Stopping Us?

Look, this isn’t a radical new concept — it's proven, scalable, and waiting for us to catch up. The question isn’t if we should do this. The only real question is: why aren’t we doing it yet — and why don’t we start now?

If we get serious about turning our own waste into power, we could not only save money and cut imports, but also make a real dent in our carbon footprint. And in the process, bring tangible benefits to ordinary people, especially those who most feel the pinch of high energy costs.

So, to the policymakers, the scientists, and the citizens: how about we stop wrinkling our noses — and start turning what we flush into fuel?
