The Fourth Plate

If you’ve ever walked through a misty forest in Kerala, listened to the rhythm of the monsoon on a tiled roof, or tasted a jackfruit curry cooked in a traditional home, you’ve already experienced something very special—biodiversity in action.

Here in this narrow strip of land between the Western Ghats and the Arabian Sea, nature thrives, weaves into our daily lives, and speaks in a thousand voices.

But what makes Kerala’s biodiversity truly extraordinary isn’t just what we see in the wild or grow in our gardens—it’s the way we, as a society, have come together to care for it.

More Than Just Wildlife: What Biodiversity Really Means Here

When we talk about biodiversity, we’re not just listing species. We’re talking about the variety of life in all its forms—from the tiniest microbes in our soil to the grand elephants of our forests, from the coconut palms lining our coasts to the medicinal plants tucked into backyard gardens.
It also includes the knowledge systems, the farming practices, and the cultural traditions that have shaped and sustained this life for generations. Scientists usually speak of biodiversity in three layers: genetic diversity, species diversity, and ecosystem diversity. In Kerala, we don’t just have them—we live them.

Genetic Diversity: The Strength Within the Species

Take a walk through a rural Chunda Kuruvakkavu, a hamlet in Kannapuram of Kannur district in Kerala during summer, and you’ll see dozens of types of mangos—each one with a name, a story, a family that’s cared for it over generations.

From the ‘Kaitha Madhuram’ smells like a pineapple to ‘Pavizharekha’ that has an unusual orange colour.  This is genetic diversity—the differences within a single species that help it adapt, evolve, and survive.

The same goes for our traditional rice varieties—Njavara, for example, is used in Ayurveda, while Chitteni thrives in saline soils. These are not just crops. They are living memories, shaped by the wisdom of farmers and the rhythms of local ecosystems.

And in the wild, even the elusive Malabar civet or the forest-dwelling lion-tailed macaque carry unique genetic blueprints that tell unique stories of evolution and survival through millennia.

Species Diversity: So Many Lives, So Many Roles

Kerala may be small, but it’s bursting with lifeforms found nowhere else in the world. Think about the Purple frog—an odd-looking, underground-dwelling creature that lives most of its life hidden from us, surfacing just for a few days during the rains to breed. Discovered in 2003 and hailed as a “once-in-a-century-find” ,  it’s like a visitor from another age, a reminder of how much there still is to discover.

Or the Neelakurinji, the blue blossom that carpets our hills once every 12 years, drawing visitors from all over. Or the vibrant birdlife in our wetlands, the butterflies in our spice gardens, the rich underwater life along our coasts.

These species aren’t just beautiful—they each play a role in the web of life, keeping our ecosystems healthy and resilient.

Ecosystem Diversity: From Hills to Coast, a Land of Contrasts

What’s most amazing is how quickly the landscape changes here. In a matter of hours, you can move from sun-drenched beaches and mangroves to evergreen forests, to misty hilltops and tea plantations.

Each of these ecosystems—rainforests, mangroves, swamp forests,  shola-grassland mosaics, estuaries, rivers, home gardens—hosts its own unique mix of life. And all of them are connected, like threads in a fabric.

Even our farming systems are ecosystems. Walk into a Kerala homestead and you’ll find a small forest—coconut, banana, yam, turmeric, pepper, maybe even a cow and a fish pond. These home gardens are among the most diverse and sustainable food systems in the world. 

People at the Heart of Conservation: Kerala’s Big Step Forward
What sets Kerala apart isn’t just the richness of its biodiversity—but how we’ve chosen to protect it.
A few years ago, Kerala became the first state in India to start preparing People’s Biodiversity Registers (PBRs) at the local village level. That means ordinary people—farmers, fisherfolk, teachers, students—started documenting the plants, animals, crops, and local knowledge in their area. It wasn’t just a list of species. It was a celebration of local heritage, and a way to protect what we often take for granted.
And Kerala went a step further—completing PBRs in every single local body in the state. That’s over a thousand communities taking ownership of their biological heritage.
Now, we’re not stopping there. Kerala is already working on the second phase of PBRs—this time, with better data, new technologies, and a sharper focus on the threats we face: climate change, pollution, invasive species, and shrinking natural spaces.

Thinking Globally, Acting Locally: A Model for the World
Kerala has also created its own State Biodiversity Strategy and Action Plan (KSBSAP)—a guiding document that sets priorities for conservation, from forests to oceans, from wild species to cultivated varieties.
But the real magic? Each Gram Panchayat is now preparing its own Local Biodiversity Strategy and Action Plan (LBSAP). That means biodiversity planning is happening at the grassroots, shaped by the people who know the land best.
In a world where conservation efforts often feel distant and top-down, this approach is deeply local, deeply democratic, and deeply effective.

Looking Ahead: Challenges, But Also Hope
Of course, there are challenges. Kerala is no stranger to floods, landslides, or climate stress. We’re seeing forests invaded by exotic species, wetlands being encroached upon, and traditional varieties being lost to commercial ones.
But we also have something powerful: a culture that respects nature, a people who are aware, and a system that believes in participation.

If there’s one message Kerala can share with the world, it’s this: biodiversity is not just a scientific concept—it’s part of who we are. When we protect it, we’re not just saving frogs or forests—we’re safeguarding our food, our health, our future, and our identity.
