Fourth International Conference on Environmental Education, Environmental Education towards a Sustainable Future: Partners for the Decade of Education for Sustainable Development, Ahmedabad, India, 26 November 2007, Education for Sustainable Development: Reaching the Masses, John Daniel, Krishna Alluri and Mohan Menon Commonwealth of Learning // In order to succeed education for sustainable development must reach the masses. This means three things. First, we must focus on those who can multiply the message, especially teachers, working not just in the classroom but through open schooling systems. Second, we must cultivate lifelong environmental learning, including that related to climate change and water resources management. Third, it follows from these two imperatives that we must use learning technologies and teaching media at scale. We describe the work of the Commonwealth of Learning in these three areas. Technology-mediated open and distance education makes it possible for the Centre for Environmental Education to teach its Green Teacher Diploma to thousands of teachers. Information technology kiosks in villages allow farmers to become lifelong learners, increasing their prosperity and lessening their environmental impact.
