Although flooding has become a routine annual affair in Bangladesh, more than half of its rivers have become unnavigable and many more have vanished, affecting the livelihood of millions in the South Asian nation. As the world is marking Environment Week this week, experts say that engineering and the dredging of river beds and reclamation of land have become necessary.
Out of 405 rivers dotting the geography of Bangladesh located at the delta, only 172 are currently navigable, according to officials. There are 57 trans-boundary rivers, including 54 common with India, and the remaining three with Myanmar.
Speaking to Anadolu Agency, River and Delta Research Centre (RDRC) Chairman Mohammad Azaz said that many rivers in Bangladesh have vanished in the last 50 years while many others lost navigability. According to the group, there were a total of 1,274 rivers in Bangladesh in 1971, when the country gained independence. Since then, a total of 507 have vanished. “Three mighty rivers – the Ganges, Jamuna (Brahmaputra), and Meghna – flow across Bangladesh and end in the Bay of Bengal. So any river control initiative taken upstream of the three mighty rivers will affect Bangladesh,” said Azaz.
Water crises
A similar situation has been prevailing around the Teesta River, which crosses northern Bangladesh. The 414-km (257-mi.) river originates in the eastern Himalayas.
“There are 11 small rivers that, depending on the water flows of Teesta River, are now dying. Teesta itself is dying and emerges as limitless char during the dry season, and agriculture depending on it faces a severe water crisis for irrigation,” he said.
A further 67% of land in Bangladesh is inundated or becomes wetland during the rainy season. But what has been the main source of concern is that the off-season rains and flooding have been affecting farmers and food security.
“Such a situation every year affects the whole food production and price hike of essentials, and farmers count huge losses,” he said.
According to government data, paddy grown on 5,000 hectares (12,355 acres) of land in the Hoar region bordering India was submerged and destroyed in a pre-monsoon flood.
“In the name of flood control mechanisms and management, we have built so many river embankments and switch gates, including in the coastal region of the country, which is not suitable for flood control, but rather destroys the fertility of canal, pond, and wetlands,” said Azaz.
He said politically influential people grabbing river land has also affected the navigation of rivers.
