Sustainable development is the overarching paradigm of the United Nations. The concept of sustainable development was described by the 1987 Brundtl and Commission Report as “development that meets the need of the present without compromising the ability of future generations to meet their own needs”.
Sustainability is a paradigm for thinking about a future in which environmental, social and economic considerations are balanced in the pursuit of development and an improved quality of life. The three inputs of sustainable development such as environmental protection, economic development and social development are inter-twined. For example, a prosperous society relies on a healthy environment to provide food and resources, safe drinking water and clean air for its citizens. The figure 1 depicts the interplay of varied aspects of the concept sustainability.
