Concept
Ecologically sustainable development
Résumé
Ecologically sustainable development is the environmental component of sustainable development. It can be achieved partially through the use of the precautionary principle; if there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation.
Also important is the principle of intergenerational equity; the present generation should ensure that the health, diversity and productivity of the environment is maintained or enhanced for the benefit of future generations. In order for this movement to flourish, environmental factors should be more heavily weighed in the valuation of assets and services to provide more incentive for the conservation of biological diversity and ecological integrity.
TOC
Effective political support is necessary for ecologically sustainable development. The mobilization of governments can be translated into action plans that are crucial to sustainable development. Development efforts can be influenced by patterns of family arrangements, work attitudes, social morality—particularly interpersonal responsibilities, hierarchy of authority, quality of scientific education and implementation, and degree of domestic stability—especially, freedom from social conflict. National policy and development planning requires three conditions to permit ecological sustainability: action-oriented values to which individuals are committed, political authorities that favour long-term ecological benefits over immediate economic gains, and a policy with a politically competent constituency.
Canada has taken an evidence based approach to sustainability development by using Environmental Sustainability Indicators as guiding tool for policy development. At the municipal level, many cities also use evidence based indicators and Ecological Indexes as a tools for policy development.
The World Conservation Strategy was published in 1980, becoming one of the most encouraging developments that uses a goal-oriented programme for political change concerning ecological sustainability.
