Contributor(s): Professor Jeffrey D. Sachs | In this public lecture Professor Sachs will talk about his upcoming book, The Age of Sustainable Development, which explains the central concept for our age, which is both a way of understanding the world and a method for solving global problems - sustainable development. Sustainable development tries to make sense of the interactions of three complex systems: the world economy, the global society, and the Earth's physical environment. It recommends a holistic framework, in which society aims for environmentally sustainable and socially inclusive development, underpinned by good governance. It is a way to understand the world, yet is also a normative or ethical view of the world: a way to define the objectives of a well-functioning society, one that delivers wellbeing for its citizens today and in future generations. This book describes key challenges and solutions pathways for every part of the world to be involved in problem solving, brainstorming, and determining new and creative ways to ensure inclusive and sustainable growth.
