After 20 months of negotiation, China, France, Germany, Great Britain, Russia and the United States reached an agreement with Iran to constrain and verify its nuclear program, in exchange for relief from international sanctions. The constraints on Iran are unprecedented among non-proliferation agreements, as are the verification procedures. Iran will be required, for 15 years, to maintain an inventory of no more than 300 kg of uranium enriched to no more than 3.67%. It will be prevented from constructing a research reactor using natural uranium.
Emergency Planning involves determining, in advance, what will be done in response to specific emergencies including identification and allocation of resources, risk management, mitigation, continuity and recovery. Staff training, using drills, exercises and real events, is an integral part of assuring that the emergency program can be implemented.
For the first time in history, more than half of the world’s population lives in urban areas; by mid-century, 70 percent of the world’s more than 9 billion people will live in cities. Enabling those cities to deliver services effectively, efficiently, and sustainably while keeping citizens safe, healthy, prosperous, and well-informed is one of the most important undertakings in this century. Success will require that we understand the physical, environmental, and human dimensions of cities in a synthetic and synoptic manner.
