On the other hand, Pakistan is nearly rainless. In 1951, it had 34 million people; now it has 152 million; in 25 years it will have 260 million. Pakistan’s rivers carry plentiful water from the Himalayas, but only in springtime. And the rivers flow through India, which also needs water and dams them. In 1960, Pakistan and India, guided by threats and promises from the World Bank, signed a treaty to share the water, and Pakistan began a system of dams and canals that got water to the places that needed it. But the canals were not maintained, so they leaked and silted up. Also, canals are heavy; they weigh down the ground and raise the groundwater to the surface, where its natural salts deposit out. So the reclaimed farmland became waterlogged and salty. ‘‘Pakistan,’’ Ward says, ‘‘is in a state of near desperation over water.’’
