The tragedy of the commons

I remember standing on a windswept hillside in Mongolia’s steppe, squinting into the distance as goat herders nudged their animals across the dry, rust-colored earth. The sky was absurdly huge—an upside-down ocean where clouds drifted like ships too lazy to reach port. There were no fences. No visible boundaries. Just movement, dust, and an unsettling quiet. A young herder leaned on his motorcycle and said—half-laughing, half-exhausted—“Too many goats. Not enough grass. But what can we do?”

What can we do, indeed.

This is not a problem exclusive to Mongolia. Or to goats. Or to grass. It’s a structural dilemma baked into the very logic of shared resources. The British ecologist Garrett Hardin named it in 1968: the tragedy of the commons. It’s not a sudden cataclysm. It’s erosion. Collapse in slow motion. A dull, frictionless grind of self-interest pushing a system past its limits—not with a bang, but with a bleating, grazing whimper.

The Logic of Overuse

At its core, the tragedy of the commons emerges when individuals exploit a shared resource to maximize their personal benefit—because the cost of doing so is diffused among everyone. Take pastureland. If everyone owns it, no one is directly responsible for its maintenance. Each herder gains by adding more livestock. But if everyone follows that logic, the land gets trampled. Overgrazed. Useless.

The key terms here—resource depletion, collective action problem, and externalities—sound like they belong in a development economics seminar. But in reality, they manifest in more tactile ways: fish that used to be easy to catch disappearing into deeper waters; plastic bags swirling through a lake where grandfathers used to swim; an atmosphere thickening with emissions so abstract they’re almost invisible—until they’re not.

What makes the tragedy tragic isn’t just the loss—it’s the predictability. Everyone sees it coming. And still, it happens.

Fish, Forests, and Failed Signals

Let’s talk fisheries. The global commons of the ocean accounts for over 90 million tons of wild fish caught annually. Yet the Food and Agriculture Organization reports that over one-third of global fish stocks are overfished. That’s not an accident. It’s arithmetic.

Take the Grand Banks off Newfoundland—a once legendary cod fishery. In the 1970s and ’80s, technological advances made it easier to harvest fish in massive quantities. The haul increased. Profits soared. Then in the early 1990s, the cod population collapsed. Moratoriums were declared. Thousands lost jobs. Decades later, the fish have not returned in viable numbers.

Same with forests. Indonesia, Brazil, the Congo Basin. The logic remains the same: one tree provides timber and cash for one logger. But the impact of that single act—erosion, biodiversity loss, changing rainfall patterns—accumulates slowly and is absorbed by ecosystems that are increasingly bad at absorbing.

There’s an eerie lag between the act and the consequence. That lag—like a delayed hangover—is part of what allows the cycle to repeat. By the time the feedback loop hits hard enough to trigger action, it’s often too late.

Climate: The Mother of All Commons Problems

Carbon emissions are the textbook case. The atmosphere, like the village commons, belongs to everyone. And no one. The incentives are badly aligned: countries gain in the short term from cheap energy and industrial growth. But the climate costs—rising seas, shifting weather, food insecurity—are collective and long-term.

Global agreements like the Paris Accord are attempts at coordination. But they remain voluntary. The penalties for cheating are soft. The benefits for acting early are faint. It’s a trust exercise performed on a fraying rope.

This is where geopolitics enters the picture. The tragedy of the commons isn’t just ecological—it’s profoundly political. Wealthy nations got rich by burning carbon. Now, developing countries are told to develop cleanly. The tension is real. India and China argue, with some legitimacy, that they are being asked to forgo the same carbon-fueled prosperity the West enjoyed.

Meanwhile, small island nations—Tuvalu, Kiribati, the Maldives—are sounding the alarm in increasingly desperate tones. Their land is literally vanishing. But they control none of the levers.

Property, Pressure, and Partial Solutions

One popular response to commons dilemmas is privatization. Give individuals ownership of resources, and they have an incentive to preserve them. This works, to a degree. But it’s a blunt tool. It doesn't apply well to migratory animals, flowing rivers, or atmospheric chemistry.

Another approach is regulation. Caps, quotas, licenses. These work when enforcement is real. But in many parts of the world, especially where state capacity is low or corruption is high, enforcement is fantasy. Laws are printed, not practiced.

Then there’s Elinor Ostrom’s work. She upended the conventional wisdom by studying real-life communities that successfully manage commons. Alpine pasture systems in Switzerland. Water systems in Nepal. Irrigation collectives in Spain. What they share: local rules, monitoring, punishment mechanisms, and—most critically—social trust.

That’s the missing ingredient in many modern attempts. Trust. Not in the abstract sense, but in the lived, communal way. When people know each other. When violations aren’t anonymous. When shame still works.

Try shaming a multinational corporation.

Data Trails and Digital Grazing

The 21st century has added new commons. Less material. Equally fragile.

Think data bandwidth. The electromagnetic spectrum. Even the cognitive space of social media. These aren’t forests or fisheries, but they exhibit the same structural fragilities. Overuse leads to degradation. Spam clogs attention. Misinformation spreads like an invasive species.

Digital commons are slippery. They don’t erode visibly. They fracture quietly. A community thread goes toxic. A platform becomes unusable. Then everyone migrates—and begins the pattern anew.

There’s also a darker kind of data commons—the troves of personal data harvested by platforms and sold for behavioral prediction. Your location. Your interests. Your fears. We’re grazing on attention—and being grazed on, simultaneously.

From Cautionary Tale to Blueprint?

It’s easy to treat the tragedy of the commons as a kind of fatalism. A shrug. A "what do you expect?" But that underestimates human capacity for adaptation.

Japan’s Satoyama landscapes (a rare exception I’ll allow for metaphor) represent a traditional model of integrated resource use—forests, fields, water systems—all managed communally, with rituals and norms passed down across generations. They’re not utopias. But they’ve endured.

Or consider the Arctic. As ice melts, new sea routes and drilling zones emerge. It’s a geopolitical free-for-all—Russia planting flags, the U.S. bolstering military presence, China calling itself a “near-Arctic” nation. But alongside the posturing, there are also multinational frameworks emerging: the Arctic Council, scientific cooperation, fisheries agreements. It’s fragile progress. But not nothing.

On a smaller scale, there are signs of innovation: community-managed marine areas in the Pacific Islands; urban commons models in Bologna; blockchain-based resource tracking (still in its awkward adolescence, but intriguing). These aren’t panaceas. But they’re attempts.

They show that tragedy is not destiny.

Slow Motion Urgency

It’s the pace that kills you. Commons problems unfold just slowly enough to allow plausible deniability. It’s never a collapse—it’s a tilt. A slant. A barely perceptible downgrade. Like boiling water slowly, the frog analogy, etc.—though frankly that frog story is apocryphal. Still, the idea sticks.

If something collapsed overnight, we’d fix it. But when a coral reef dies over 20 years, when bees vanish gradually, when air gets incrementally thicker with invisible pollutants—it’s easy to adapt. To normalize. Until you can’t.

That’s what makes the tragedy so cunning. It hijacks short-term rationality and converts it into long-term ruin.

The Commons We Haven't Invented Yet

Here’s a twist: not all commons are inherited. Some are created.

The Antarctic Treaty System wasn’t born of necessity. It was designed—intentionally—to protect a global commons before it was exploited. No military bases. No drilling. Just science and cooperation. For now.

What if outer space became our next commons success? Or failure?

The moon is already in play. So are Earth’s orbits, cluttered with junk from decades of launch debris. Elon Musk’s Starlink has launched over 5,000 satellites, with plans for tens of thousands more. That’s a digital commons too—one that can be ruined by a single high-speed collision.

The rules we set now—who gets to occupy orbital real estate, who cleans up debris, who owns moon minerals—will shape not just the future of space, but the question of whether we’ve learned anything from Earth.

A Mongolian Epilogue

Back on that hill in Mongolia, the young herder shrugged and drove off. Dust curled behind him like a tired ghost. I walked back toward the yurt camp, trying to make sense of what I’d seen. Not a catastrophe. Not yet. But a pattern. A warning. A reminder that when everyone acts alone, we all end up poorer together.

And maybe that’s the final irony: the tragedy of the commons isn’t about scarcity. It’s about abundance squandered by misaligned incentives. It’s not a tale of need. It’s a failure of imagination.

We have the tools. We know the patterns. We’ve written the warnings.

We’re just not very good at reading them in time.
