1. SCIENCE FOR SUSTAINABLE DEVELOPMENT

2. It is the development that meets the needs of present without compromising the ability of future generation. Sustainable development

3. The concept of SD has been rooted in distant pasts . It is evident from the works of Thomas Malthus on the dangers of population growth in the late 1700s. The concern began with the 1974 UN Cocoyoc Declaration, which addressed the use of natural resources in sustainable way. In 1982,UN established the World Commission on Environment & Development (WCED) headed by Gro Harlem Brundtland , known as Brundtland Commission. They published their report Our Common Future in 1987 which got the worldwide attention on Sustainable Development. More recently the UN sponsored United Nations Conference on Environment & Development (UNCED) in 1992 in Rio de Janerio The conference delegates approved 5 agreements designed to foster the diff. Aspects of sustainablity . HISTORY OF SD

4. Environment Economy Society 3 key elements of SD

5. 3 pillars -social, economic and environmental columns. equally balanced with long term profitability, maximum environmental care and social responsibilities. Pillers of Sustainability

6. Environment sustainability involves decision making and taking actions to protect the natural world, by focusing on preserving the capability of the environment to support human life. Biodiversity Materials Energy Biophysical interactions E nvironmental S ustainability

7. The use of various strategies for employing existing resources optimally so that a responsible & beneficial balance can be achieved over the longer term. Money & capital Employment Technological growth  Investment Economic Sustainability

8. The ability of a community to develop processes & structures which not only meet the needs of current members but also support the ability of future generations to maintain a healthy community. Human density Equity Quality of life Political structures Social sustainability

9. Conservation of ecosystem Sustainable development of society Conservation of biodiversity Population control Conservation of human resource Principles of SD

10. Threats Climate change Resource depletion Energy consumption Population growth Species extinction Using appropriate technology 3-R approach Promoting environmental education Population stabilisation Conservation of non renewable resources Usage of renewable resources. Measures

11. New energy and propulsion technologies that will reduce emission of climate damaging green house gases. Renewable energy- solar energy, wind energy etc ENERGY USE

12. Electric cars, hydrogen engines, natural gas engines, fuel cell engines – eliminating motor vehicle emissions. Environmental compatible mobility

13. Advances in medical diagnosis & therapy, in environmentally compatible industrial and agricultural production. Biofilters and waste water treatment – cleanup polluted sites. Biotechnology

14.  Sustainable chemistry. Design eco friendly process. Plastics are replaced by green plastics . Concept of pollution control and zero waste. Green chemistry

15.  Developed countries need to change their production and consumption patterns, with the limiting use of fossil fuels. A far more optimistic future is attainable only by changing development policies, incentives and actions. Conclusion
