Making a festival of urban biodiversity

In a fast-growing city like Delhi, surrounded by traffic, concrete, and constant movement, it is easy to assume that nature exists somewhere far away from us. Yet the city continues to pulse with life. Birds move through its skies, insects hum among roadside trees, fungi emerge quietly after rains, and small plants find ways to grow through cracks in pavements. Delhi is not separate from nature—it is part of it.

But how often do we stop to notice?

City Nature Challenge is an invitation to rediscover the living city around us. As part of a global citizen science movement, the challenge encourages people to observe and document biodiversity in their neighborhoods using the iNaturalist platform. Participants photograph plants, birds, insects, fungi, and other organisms and share these observations, contributing to a growing global database of biodiversity.

What began years ago as a friendly competition between two cities has now grown into a worldwide effort involving hundreds of cities and thousands of participants. Each observation—no matter how small—adds to our collective understanding of the natural world that persists within urban spaces.

For Delhi, the challenge is particularly meaningful. The city contains an extraordinary range of habitats: wetlands, ridge forests, neighborhood parks, agricultural edges, university campuses, and informal green spaces. These places quietly support a surprising diversity of life. Yet much of this biodiversity remains undocumented.

City Nature Challenge 2026: NCT of Delhi hopes to change that.

Over a few days during the challenge, citizens across the city will step outside with curiosity. Students, naturalists, photographers, researchers, and neighborhood residents will explore parks, campuses, wetlands, and streets to record the living organisms they encounter. Guided biodiversity walks, campus BioBlitz events, and community observations will collectively contribute to a larger picture of Delhi’s ecological richness. But the challenge is not only about collecting data.

We imagine it as a festival of urban biodiversity—a moment when the city pauses to notice the life that surrounds it. Through shared walks, photographs, conversations, and discoveries, participants begin to see familiar places differently. A roadside tree becomes a habitat, a pond becomes a migratory stopover, and a patch of grass reveals an entire miniature world.

In the process, new connections emerge: between citizens and nature, between institutions and communities, and between curiosity and scientific knowledge.

Through documentation, storytelling, and collective participation, City Nature Challenge Delhi 2026 hopes to nurture a culture of urban ecological awareness—one where people recognize that the city is not only a place for people, but also a shared home for countless other species.

Because sometimes, the first step toward conservation is simply learning how to look.
