RAJSHAHI (Bangladesh), Oct 29 — In Bangladesh’s parched Barind region, 72-year-old Bikash Soren remembers when the Ganges river flowing in from neighbouring India carried large boats past his village year-round.

But the South Asian country is now blighted by persistent water shortages — and the expiration of a long-term water-sharing deal with Delhi in just a few weeks’ time threatens tens of millions of livelihoods.

“For almost three months a year, you hardly see the river flowing,” the Protestant priest said.

Two farmers killed themselves last season, he added, after dwindling water levels left their rice and wheat crops in tatters.
