Globally, life expectancy at birth has increased by more than 30 years over the last century during which, at the same time, fertility declined. This altering of the population structure in developed as well as developing regions across the globe will have implications for present and future generations in terms of the development of “The Future We Want”. Against this background this Trinity Term 2018 Seminar Series “Leave no one behind” – Sustainable Development Goals, Ageing and Global Development offers 8 seminars by an array of international scholars, policy makers and practitioners to critically engage with the Sustainable Development Goals (SDGs) at the interface of ageing and generational development. The 2030 Agenda for Sustainable Development sets out a universal plan of action to achieve sustainable development in a balanced manner and seeks to realize the human rights of all people. It calls for leaving no one behind and for ensuring that the SDGs are met for all segments of society, at all ages, with a particular focus on the most vulnerable-including older persons. Preparing for an ageing population is vital to the achievement of the integrated 2030 Agenda, with ageing cutting across the goals on poverty eradication, good health, gender equality, economic growth and decent work, reduced inequalities and sustainable cities. Therefore, while it is essential to address the exclusion and vulnerability of-and intersectional discrimination against-many older persons in the implementation of the new agenda, it is even more important to go beyond treating older persons as a vulnerable group. Older persons must be recognized as the active agents of societal development in order to achieve truly transformative, inclusive and sustainable development outcomes. It is anticipated that the series will provide a platform for future internal cross-divisional and international research/policy/practice collaboration.
