Description

The project

Spearheaded by the principal architect of Uthan Design Studio, the Kalamcchara Trail is a pioneering environmental intervention located within the world's largest refugee camps in Cox's Bazar, Bangladesh. The region heavily suffers from a critical lack of vegetation, safe access routes, and biodiversity, requiring immediate sustainable action.

To address these challenges, the project introduces an alternative pedestrian walkway designed around the principles of nature-based solutions (NbS). By focusing on establishing a robust blue-green network, the trail directly improves the local microclimate while restoring lost ecological balance in a highly vulnerable and densely populated settlement.

Beyond its environmental impact, the trail serves as critical humanitarian infrastructure. It is designed to mitigate disaster risks like flooding and landslides, ensuring a safer environment for displaced populations. Through active community participation in the planning process, the project delivers a dignified, climate-resilient public space that promotes biodiversity and social inclusion.

Uniqueness

What makes it particular

Nature-Based Solutions (NbS): The project uniquely utilizes ecological engineering rather than conventional hardscapes, integrating a blue-green network to revive local vegetation and improve the micro-climate within a highly congested settlement.

Humanitarian Focus: Unlike standard urban trails, this design specifically addresses the severe spatial and ecological deficits of the world's largest refugee camps in Cox's Bazar, prioritizing safe access for displaced and vulnerable populations.

Disaster Risk Reduction: The walkway acts as a functional resilience mechanism, strategically planned to mitigate urgent disaster risks such as seasonal flooding and landslides inherent to the camp's high-pressure environment.

Community-Led Approach: Emphasizes deep social inclusion and participatory planning, actively involving camp residents—especially women and children—in the environmental restoration and design process.

Biodiversity Restoration: Actively reverses environmental degradation by creating a dedicated ecological corridor that promotes local flora and fauna, transforming barren refugee areas into sustainable, living landscapes.
