Recently, however, Brazil has changed its course, reducing the rate of deforestation by 83 percent since 2004. At the same time, it has become a test case for a controversial international climate-change prevention strategy that places a monetary value on the carbon stored in forests.

Since their inception in 2000, The Millennium Development Goals have revolutionized the global aid business, using specific targets to help mobilize and guide development efforts. They have encouraged world leaders to tackle multiple dimensions of poverty simultaneously and provided a standard for judging performance. As their 2015 expiration looms, the time has come to bank those successes and focus on what comes next.

The crisis of democracy identified in the 1970s never really went away; it was just papered over with temporary solutions and obscured by a series of lucky breaks.

In the next decade, China will continue to rise, not fade. Its leaders will consolidate the one-party model and, in the process, challenge the West's smug certainty about political development and the inevitable march toward electoral democracy.
