The correct answer is C. 2005 – 2015.
The United Nations Decade on Education for Sustainable Development (DESD) was a global initiative that ran from 2005 to 2015. The goal of the DESD was to promote education for sustainable development (ESD) as a means of achieving the Millennium Development Goals (MDGs) and the broader goals of sustainable development.
ESD is a holistic approach to education that aims to equip learners with the knowledge, skills, and values they need to live and work in a sustainable way. It is based on the principles of sustainable development, which include social, economic, and environmental sustainability.
The DESD was a major success, with over 100 countries participating. It helped to raise awareness of ESD and its importance, and it led to the development of new ESD policies and programs. The DESD also helped to build a global community of ESD practitioners and advocates.
The DESD ended in 2015, but its legacy continues. The Sustainable Development Goals (SDGs), which were adopted by the United Nations in 2015, include a goal on education for sustainable development (SDG 4). The SDGs also recognize the importance of ESD in achieving the other SDGs.
The DESD was a major step forward in the global effort to promote education for sustainable development. It helped to raise awareness of ESD and its importance, and it led to the development of new ESD policies and programs. The DESD also helped to build a global community of ESD practitioners and advocates. The legacy of the DESD continues, as ESD is now recognized as a key element of the global effort to achieve sustainable development.
