The book focuses to provide a roadmap for transition into a sustainable world from its current unsustainable trajectory. Unlike the 17-SDGs without the priority and interrelationship among the goals or more than 300 definitions of sustainable development; the book envisions a sustainable world which is simultaneously safe, healthy and just. While providing a roadmap, the book discusses how a spiral of crises has emerged at the dawn of 21st century, in spite of showcasing miracles of science and technology. The book shows that the challenges of 21st century are trapped in a vicious circle and cannot be resolved by science and technology alone, without taking into account the ‘socio-economic’, and ‘cultural-ethical-behavioural’ dimensions of the problems. Thus the book attempts for holistic solution of the systemic challenges instead of a part of the problems as addressed through the traditional fragmented disciplinary, legislative, departmental and silo or sectorial approach to governance. The roadmap for transition into a ‘Sustainable World’ provided in the book consists of some transformative strategies for integrated action which includes: adopting new form of goals, introducing a system-wide accountability, reorienting governance of ecosystem services, reorienting governance of built environment and human settlements. Each of the strategies is as part of the grand vision for a Sustainable State or World and is mutually reinforcing and complementary. The central and transformative role of education in the roadmap for a sustainable world is discussed in detail. Attributes and competencies of graduates and citizens of the world and strategies for transforming ‘Indian Education’ into a holistic and multidisciplinary system as envisaged in the National Education Policy-2020 are provided. Since the challenges are inherently multi-disciplinary in this 21st century, this book is ideally suited for everyone and for all educational disciplines and professionals such as Engineers, Managers, Lawyers, Policy Makers, Administrators, Corporate Leaders, Social Scientist, Political and Social Leaders, Business, Organizational and Technical Leaders, NGOs, Economists and Scientists.
