Pre-registration required Since its inauguration in 2007, the Forum roundtable has provided ample opportunity to key university actors from around the world to discuss collaborative approaches in building the emerging field of Sustainability Science. This year the focus will be on Sustainability Science and the next global summit on sustainability, the United Nations Conference on Sustainable Development (Rio+20) to be held in Rio de Janeiro in 2012. It will call the world's attention to and direct action toward addressing difficult challenges the planet is facing, including reducing poverty, conserving natural resources, and overcoming financial and economic crisis. This AAAS roundtable is an opportunity to bring together academic experts, business leaders, and policy-makers to help define and shape ideas to feed into the international policy process that is being formulated in advance of the summit. Previous summits have produced global treaties (including the UN Framework Convention on Climate Change) and led to important partnerships to promote sustinability issues (as demonstrated during the 2002 World Summit on Sustinable Development). The AAAS Sustainability Forum will help embed the latest policy considerations and science research into the planning process and help identify a potential road map forward in addressing issues of global sustinability. Pre-registration is required. For more information, contact Linda Stroud, lstroud@aaas.org.
