From connectivity to migration or climate change, infrastructure touches every aspect of human life. When effectively planned, financed, delivered, operated, and maintained, infrastructure will open social and economic opportunities for all. This contributes to equitable and sustainable development, as well as to peace and security. Recent research completed by UNOPS and the University of Oxford, further supported with an essay by The Economist Intelligence Unit, reveals key insights about the critical role of infrastructure. Challenges, best practices and tools from the cooperation perspective will be addressed in this session.
