Water in Bangladesh is either unsafe or pricey

But there is a new set of ideas to fix an old problem

BANGLADESH, WHICH sits within the world’s largest river delta, has no shortage of water. Alas, barely any of it is drinkable. Much of the country’s surface water contains high levels of poisonous arsenic, owing to both man-made and natural causes. The effects of climate change increasingly sully the rest with salt, even in wells dug deep. As cyclones and tidal surges from the Bay of Bengal intensify, sea water fills the delta. Salt-ridden soil makes growing rice impossible, forcing Bangladeshis to abandon low-lying regions—home to a quarter of the country’s 170m people—in favour of more fertile areas or cities.
