By 2050, in just 35 years, our world will be completely different. China will be grappling with the consequences of half a century of workforce decline. Europe will be much older, far less white and less Christian. Developing countries will be mainly urban, rather than rural. Africa will have grown enormously -- Nigeria alone will have twice as many people as Western Europe -- and the continent as a whole will have a population almost as large as that of India and China combined. These changes will pose enormous challenges in regard to migration, economic growth and stable governance. Rising to these challenges will require new forms of international and intergovernmental cooperation, and innovative policies based on embracing this new world. The speaker will share his insights on what these innovative policies could be.
