Technology defined by their environmental performance
Sustainable technology is characterized, compared to commonly used techniques in a society at a given time to meet the same needs, a lesser imprint on the nature of human activities, due to their environmental performance. This ecological added value must, on pain of being quickly outdated, be constantly renewed in a continual improvement process through the various industrial and administrative institutions. Sustainable technologies allow both:
• Optimizing the use of resources (energy and material): reduced consumption, better utilization (yield conversion), possibility of recovery (heat) or using new “beds” (renewable energy, secondary raw materials)
• A reduction in the environmental impact preventive actions (reduction of emissions, waste and pollution) or curative (treatment, pollution control), and monitoring and measurement (metrology, observation) environments (water, air, soil, bio- diversity) and sites.
This technology covers many sectors, which lead in practice to consider the following distribution: renewable resources, energy and raw resources. Then the effectiveness of “systems”: products, processes and applications in industry, transport, construction… and healing environmental technologies (clean-up, rehabilitation) and preventive (substitutes, monitoring systems). Which to build a viable economic offer in the context of green growth, sustainable technologies benefit under the government support.
Driving Sustainable Development
The Millennium Development Goals (MDGs) have led too much debate and during which discussions were reviewed the progress made to ensure sustainable technology throughout the world, and prepared tactics to implement for post-2015 period. At the Conference of the United Nations Rio in June 2012, dedicated to sustainable development, governments have agreed with develop a series of objectives Sustainable technology: the discussions then addressed the role of science, technology and innovation, and the question of the rights of intellectual property. Recently, ICSU (International Council for Science) and the Department of Economic and Social Affairs of Nations United (UN-DESA) convened a group of experts at the headquarters of the United Nations 2. In June 2012, the IPA(InterAcademic Panel, a global network of science academies) made a statement with the Population and Consumption theme. Finally, several academies and learned societies, including the National.
The American Academy of Sciences, has published reports on development issues. Science academies are dedicated to provide decision makers in their country of data relevant for decision support, particularly in terms of progress. The passed eight years, a group of academies sent short joint statements to governments gathered at the annual summits on various global issues. Some of them, such as energy, climate change, water, health and infectious diseases resilience disasters related to sustainable development.
This year is the National Academy of Sciences India which hosted the academies to continue the process. Many sciences and technology have been made over the passed eight years, including for information technology and communication and resource extraction techniques are natural. However, the challenges the world faces remain major, and have even significantly increased, in particular about the steady increase of the population globally, climate changes observed and the resulting impact on the ecosystem. Reply the basic needs of humanity today and tomorrow, and remain a major challenge.
The work is engaged in the global community to fix the Sustainable Development goals for years to come. Here are our perspectives on the role to perform science, technology and innovation in steering the sustainable progress. Demographic changes occur rapidly and comprehensively. Although it is possible to achieve a level of semi-stationary population at the end of the century, the projections show that the world population will reach nearly 9 billion people in 2050, based on a current figure of about 7 billion.
