Coastal Megacity Karachi Is Running Out of Water (earther.com)

The Pakistani megacity of Karachi, home to more than 20 million people, is among the most water-stressed cities in the world, only able to meet half of its daily water demand. From a report: Karachi requires 1,100 million of gallons per day (mgd), but only receives 550 mgd, according to the Karachi Water and Sewerage Board (KWSB). Karachi's water is sourced from the Indus River via Keenjhar Lake, which sits more than 90 miles away from the city. The water shortage in Karachi is linked to myriad factors including climate change, mismanagement of water resources, and corruption. Most of all, however, a rising population increasing at a rate of 4.5 percent a year creates a strain on the finite water supply. Pakistan ranks in the top ten of countries worst affected by climate change, and water shortages are likely to deepen in both intensity and frequency in the coming decade.

    corruption, water mismanagement AND a massive population explosion over the last half century. climate change on top of all that I doubt has even a measurable effect by comparison.

    Cut off all emigration from Pakistan and let them deal with their own problems. Overpopulation has its consequences. China knew it and implemented the One Child Policy to great success. Europe (and colonies) and East Asia have dealt with their population problems and now have stable or declining rates. If South/West Asia, the Mid East and Africa can't figure it out themselves, we're not going to bail them out by taking millions of their excess people.

    Harsh as it sounds, that is exactly the core problem: If you bred like crazy in a resource-starved situation, you will eventually run into mass die-off that normalizes your population numbers to something far lower. Of course, this also comes with a civilization collapse when it happens to a human population. In theory, a human population can avoid this catastrophe by restricting its own breeding to what is sustainable, but apparently this one here cannot.

    Or in other words, they are going towards a horrible catastrophe, all of their own making.

    You got it! Karachi is home to more than 20 megapersons and is only able to meet about 5 decidemands of water per day.
