  • How science is tackling Pakistan`s water shortages

    Efforts are underway to preserve Pakistan's water supply as climate change, population growth and a stressed irrigation system take their toll. Water availability per person has already fallen by more than 500 per cent since the 1960s and is likely to decrease even further to just 550 cubic metres by 2025 — compared with the 9,800 cubic metres currently available in the United States, for ...
