Since the Rio Earth Summit in 1992 countries around the world have been developing and implementing National Sustainable Development Strategies (NSDS). Sustainable Development competes with many deeply entrenched values and therefore progress has been slow. Tensions between long term and short term thinking, and between economic growth and social and environmental sustainability, are not easy to resolve. The NSDS process has gained impetus following the 2002 World Summit on Sustainable Development, where it was agreed that countries need to take immediate steps to elaborate and formulate NSDS systems that can continuously improve. The UN Guidance Document describes an NSDS as a comprehensive, adaptable, continuous and long term undertaking that helps a country to achieve economic prosperity and higher levels of social welfare, while at the same time preserving the environment. An NSDS is not just something that can be put together in a document and be promulgated. Development of an NSDS requires multi-stakeholder participation, partnerships, country ownership, shared vision with a commitment to continuous improvement, capacity development and the ability to build on existing knowledge and processes and a clear focus on outcomes. Education is a central dimension of achieving sustainable development, and needs to be incorporated into the NSDS process. Learning is central to the process of NSDS development and implementation.
