The proposed mega hydropower project in Tibet, initiated by the Chinese government, has raised significant concerns for Bangladesh and its ecological future.
As per a report published in this newspaper on Friday, the Yarlung Zangbo River, which transforms into the Brahmaputra as it flows southward, is a vital lifeline for millions in Bangladesh, supporting both the country’s ecology and biodiversity.
As the project moves forward, Bangladesh must engage in a proactive dialogue with China and other stakeholders to address the potential ramifications.
International norms dictate that upstream countries should inform downstream nations before constructing dams or barrages on shared rivers.
However, this crucial communication has yet to occur, leaving Bangladesh vulnerable to the consequences of a project that could produce an astonishing 300 billion kilowatt-hours of electricity annually.
While the promise of renewable energy is enticing, the potential risks associated with the dam cannot be overlooked.
Experts warn that the construction of such dams can lead to significant water loss due to evaporation and sediment disruption.
The Brahmaputra relies on a delicate balance of sediment flow, which is essential for maintaining its ecological integrity and supporting local fisheries.
The trapping of sediment in reservoirs can lead to an increased erosion and a decline in land formation downstream, threatening the livelihoods of countless communities.
Former officials and environmental advocates have rightly called for Bangladesh to engage in dialogue with China to clarify the potential downstream effects of the hydropower project.
This conversation must extend beyond bilateral discussions with India or China; it should involve all countries sharing the river basin, including Bhutan.
Moreover, Bangladesh should prioritise the Brahmaputra in its water management policies, recalculating the contributions of upstream countries and advocating for international safeguards.
Signing and ratifying key international conventions on transboundary rivers, such as the UN Watercourses Convention, will strengthen Bangladesh’s position in negotiations.
As concerns mount over the potential ecological impact of the Tibet project, it is crucial for Bangladesh to take a proactive stance.
Engaging with upstream countries and multilateral forums will be vital in safeguarding the interests of its citizens and ensuring the sustainable use of the Brahmaputra River for generations to come.
We urge the authorities concerned to take action immediately. The future of this vital waterway depends on timely action.
