ROLE OF DESIGN- NATURE OF DEVELOPMENT
Sustainability is living in this finite world in such a way that other people and species may live here too, now and in time to come. Sustainability is supported by the balance of environment and society. The smooth co ordination of these two is the economy. The money-capital tool, originally an aid to speed up barter, has taken over and set itself up as the third leg of the stool. But it has become the distorted monster. Planning is supposed to be a spatial tool to allow us to use land wisely. The idea of sustainability requires us to recall at every step that we are stewards in our time, not outright owners. We need measures to encourage good stewardship, some of which may be enshrined in planning policy, others supported by fiscal structures.
