From a demographic point of view, more than 9 billion people are expected to live on planet earth in 2050, two-thirds of them in cities. Actually, the entire anticipated population increase is to take place in urban areas, with over 90 percent in Africa, Asia, and Latin American and the Caribbean ; so, global urbanization has long since shifted to developing countries and emerging economies. Approximately 2.7 billion people live in urban agglomerations in developing and emerging economies today; in 2030, that number will rise to 3.9 billion – and reach 5.1 billion in 2050. Around 95 percent of this urban momentum is going to take place in metropolitan regions. Established mega regions like Sao Paulo or Mumbai, as well as urban agglomerations composed of rapidly growing small and medium-sized cities will become the key living and economic spaces of the urban millennium.
global development agenda
As the 2015 deadline for achieving the Millennium Development Goals approaches, much thought is being devoted to what should succeed that framework for measuring global progress against hunger, disease, and poverty. Any successor framework must reflect global aspirations and arise from a rich consultative process. I believe that the new framework must embrace a broader understanding of development — one that is relevant for all countries, rich as well as poor.
The world today looks very different from a few years ago. Many countries have high levels of debt that could make it difficult to undertake spending initiatives for many years. Financial sector incentives and regulation may have to be rethought, existing growth models refined to deliver sufficient new employment opportunities, and the functioning of the international monetary system revisited.
