Nation-states continue to think in terms of maintaining control of conventional agricultural and industrial raw materials (like food and oil) by encompassing them within their territories, neglecting to put in place rules of behavior that will govern the distribution of goods like water and technology when these are at least as likely to be the source of interstate conflict in the future. Hitherto restrictions on technology transfers—like those governing the export of high-speed computers that can be used in missile telemetry—arose from state conflicts like the Cold War. In the future such restrictions may themselves be the cause of conflict.
