For hundreds of years, water has formed the id of Bengal. Bangladesh’s rivers and canals are greater than waterways—they’re lifelines for agriculture, transport, and resilience towards floods. Bengal’s historical past even reveals that irrigation canals had been dug practically three thousand years in the past.

Dhaka itself as soon as boasted round 65 canalsconnecting neighborhoods and easing monsoon waterlogging. Right this moment, surveys fluctuate: some listing 43–50 nonetheless functioning, whereas others recommend solely 26 stay. The decline has been stark. A examine by the River and Delta Analysis Centre (RDRC) discovered the capital misplaced practically 120 km of canal size—about 307 hectares—for the reason that Forties to encroachment and neglect.

Dhaka: As soon as a “Metropolis of Canals”

Lengthy earlier than automobiles and concrete, water formed Dhaka’s story. Within the Mughal period, the town was known as the “Venice of the East.” Canals like Dholaikhal, Segunbagicha, and Narinda had been busy commerce routes. They linked rivers to markets and carried boats filled with jute, spices, and textiles.

When Subedar Islam Khan made Dhaka the capital of Bengal within the early 1600s, he ordered the digging of Harmful. It boosted commerce and likewise protected the town from floods. These canals had been greater than waterways—they had been a part of Dhaka’s tradition, economic system, and security. Dropping them isn’t just an environmental challenge. It additionally means dropping a part of the town’s id and historical past.

From Useful resource to Danger

Right this moment, that proud legacy is at risk. Unplanned development, unlawful land grabs, rubbish dumping, and neglect have turned flowing canals into stagnant waste pits. The place boats as soon as moved and youngsters performed, folks now face dangerous smells, mosquito swarms, and waterborne illnesses.

The value is excessive. Dhaka’s two metropolis companies spent greater than Tk 30 billion previously 12 years combating waterlogging. But residents nonetheless endure. Research present that in some years, poor households misplaced as much as 8% of their earnings as a result of flood harmwell being care prices, and misplaced workdays.

Well being & Social Impacts of Misplaced Canals

The lack of canals has not solely harm drainage but additionally made well being dangers worse. Stagnant, garbage-filled water turns into an ideal breeding floor for mosquitoes. This has led to rising instances of dengue and chikungunya. The World Well being Group warns that poor water programs in South Asian cities gas the unfold of those illnesses.

For low-income householdsclogged canals imply flooded houses, unsafe consuming water, and better medical payments. A examine in 2017 discovered that some households in Dhaka misplaced as much as 8% of their yearly earnings due to flood harm and well being prices.

Youngsters face the most important hazard. Polluted water causes diarrheal illnesswhich continues to be one of many major causes of kid deaths in Bangladesh.

Local weather Resilience and Flood Safety

Dhaka persistently ranks among the many world’s most climate-vulnerable cities. With extra intense rainfall, the chance of flash floods grows yearly. Canals act as pure buffersabsorbing extra stormwater and channeling it into rivers. When they’re blocked or encroached upon, water has nowhere to go—resulting in hours and even days of waterlogging.

Restoring canals is greater than an city beautification undertaking; it’s a low-cost, nature-based adaptation technique. Whereas Dhaka invests billions in pumps and drainage programs, research present that reviving simply 15 canals might resolve as much as 80% of waterlogging issues.

A Collaborative Effort: #CholoKhaalBachai#

In the course of this disaster, Berger Paints Bangladesh and Footsteps Bangladesh began the #CholoKhaalBachai# marketing campaign. It’s a volunteer-led effort to carry canals again to life. Their newest work targeted on the Bottola Mazar Canal in Hazaribaghwhich had turn out to be little greater than an open rubbish pit.

In simply 12 daysgreater than thousand volunteers and residents eliminated 35 truckloads of waste. For the primary time in years, water might move once more. The cleanup diminished flooding, improved air high quality, and lowered well being dangers for lots of of households.

It even launched Bangladesh’s first anti-pollution paint that absorbs greenhouse gases. However past merchandise, the actual lesson is within the mannequin: a enterprise, a youth nonprofit, and the neighborhood working collectively for city renewal.

Coverage & Governance Challenges

But, large challenges stay. Dhaka WASA, RAJUK, and the town companies all share canal obligations, however their coordination is weak. Legal guidelines exist to cease land grabs, however enforcement is poor.

Encroachment continues. Builders, generally highly effective ones, take land alongside canals. Cleanup drives are launched, however rubbish and unlawful buildings typically return inside months. With out stronger oversight, these efforts threat changing into symbolic as a substitute of lasting.

Consultants say Dhaka wants one lead authority for its water our bodies. They name for harder legislation enforcement, neighborhood monitoring, and long-term planning to make canal restoration everlasting.

Past One Canal: What Comes Subsequent?

The cleanup of the Bottola Mazar Canal is a giant win, however the work can not cease right here. To maintain canals alive, specialists say Dhaka wants:

• Group monitoring to cease folks from dumping waste once more.
• Coverage enforcement to dam land grabs.
• Public schooling so folks see the hyperlink between trash and water security.
• Scaling up the mannequin to revive Dhaka’s 26–50 remaining canals.

Different cities present this could work. Singapore and Ahmedabad, India cleaned up their waterways by means of robust partnerships between the private and non-private sectors. Dhaka can adapt these classes in its personal approach.

Future Imaginative and prescient: A Dhaka with Restored Canals

Dreaming of a Dhaka with clear canals shouldn’t be fantasy—it’s doable. Restored canals might carry:

• Much less flooding and decrease restore prices for households.
• Higher well beingwith fewer waterborne illnesses.
• Inexperienced corridorsnew parks, and even eco-tourism.
• Financial developmentsince houses close to clear water rise in worth.

Cities like Seoul reworked with the Cheonggyecheon Stream undertakingand Singapore’s Kallang Basin blends flood management with recreation. Dhaka, too, can see canals not as drains however as treasures—a part of a protected, trendy, and livable metropolis.

Editorial Takeaway

The revival of Bottola Mazar Canal reveals what is feasible when companies, nonprofits, and residents unite. It’s not simply CSR—it’s a imaginative and prescient for city survival.

For Dhaka, the stakes are excessive: clear canals imply diminished flooding, higher well being, and a extra livable metropolis. For Bangladesh, initiatives like #CholoKhaalBachai# could mark the start of a brand new mindset—the place waterways are protected as crucial infrastructure relatively than deserted as waste pits.

As one volunteer put it: “We cleared rubbish, however what we actually restored was hope.”
