In the mist-shrouded hills of the Chittagong Hill Tracts (CHT), where the monsoon’s fury meets the daily grind of survival, a silent crisis is unfolding. For indigenous communities—Chakma, Tripura, and Bangali—the struggle for water, sanitation, and hygiene (WASH) is not just a matter of convenience but of endurance. A new study by Sumaya Tabassum, a researcher at the Rajshahi University of Engineering & Technology, sheds light on the harsh realities these communities face, revealing how climate change and economic pressures are pushing them to the brink.
Tabassum’s cross-sectional survey of 81 households across four settlements paints a stark picture. Families here spend an average of 7.8 minutes fetching drinking water and a staggering 19.4 minutes for domestic use. But these aren’t just numbers—they’re lost hours that could be spent on education, farming, or even rest. “The burden of water fetching is not just physical; it’s a cycle of lost opportunities,” Tabassum notes. The situation worsens during seasonal scarcity, with 60% of households reporting chronic or seasonal shortages. For many, the distance to water sources is a critical factor: every additional 100 meters adds 3.1 minutes to their domestic fetching time, while higher climate shock indices tack on another 1.8 minutes.
The study also highlights a troubling shift in agriculture. Faced with water scarcity, farmers are abandoning paddy cultivation—a staple crop—to invest in tobacco, which demands less water but comes with high financial risks. “They’re trading food security for short-term gains, often at the mercy of high-interest loans,” Tabassum explains. This economic strain exacerbates their vulnerability, leaving them trapped in a cycle of debt and scarcity.
The research points to a glimmer of hope: nature-based solutions and circular economy principles could offer a way forward. By integrating proper health, sanitation, and technological knowledge—along with interest-free financing—these communities could break free from the cycle of scarcity. The findings align with Sustainable Development Goal 6 (SDG 6), emphasizing the need for targeted WASH investments that build resilience against climate shocks.
For the energy sector, this study underscores a critical point: investing in resilient WASH infrastructure isn’t just a humanitarian effort—it’s a strategic imperative. Reliable water access reduces the energy burden of water fetching, freeing labor for productive activities. It also mitigates health risks, lowering the long-term costs of healthcare and lost productivity. As climate change intensifies, the commercial case for sustainable WASH solutions becomes undeniable.
Published in *Discover Sustainability*, this research challenges policymakers and industry leaders to rethink how we address WASH challenges in vulnerable regions. The Chittagong Hill Tracts may seem remote, but the lessons here ripple across borders, offering a blueprint for resilience in the face of climate change.
