A decade has passed since the United Nations (UN) Decade of Education for Sustainable Development (hereafter, DESD, 2005–2014) was initiated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the world community to combat international threats against both human and ecological sustainability. Understanding and addressing global issues of sustainability affecting individual nations and communities are at the heart of Education for Sustainable Development (hereafter, ESD). These issues come from the three different but interconnected spheres of sustainable development: environment, society and economy. Such environmental issues as climate change, water shortages and biodiversity loss, social issues like HIV/AIDS, migration and urbanisation, employment, human rights, gender equity and peace and human security, and economic issues such as poverty and corporate responsibility and accountability are all highly complex and will require sophisticated educational strategies for this and the next generations to find solutions (UNESCO, 2005).
