Abstract

The issue of sustainable development, in the recent decades has been core argument. The guiding principle of sustainable development is development that meets the needs of present without conpromising the ability of future generations to meet thier own needs. Sustainable development recognises the interdependence of environmental, social and economic systems and promotes equality and justice through the empowerment of people a sense of and giving them global citizenship. According to the idea of sustainable development, development needs equality between parts of socio-economical systems. In fact equality and sustainability are two aspect of a single concept.
In this paper we discuss the components of sustainable development including, people, resource, space, and the role and importance of these components in the development process.
However, in recent decades it has become apparent that social, economical and environmental problems encompass more than just science and economics, and that a new innovative model is needed to supplant the traditional decision - making approches.
