Urbanisation in India today is synonymous with booming unplanned and unsustainable mega cities .To mitigate the impact of this urban explosion and plan for the future, it is imperative to balance the demands of high growth on one hand and ensure sustainable growth on the other. In essence, economic, social, and environmental planning has to be linked to spatial/regional planning, to come up with a comprehensive strategy on a regional scale that provides form for sustainable emergent systems .Such a task is complex, given the scale, variation in environmental and natural conditions, lack of knowledge of the needs on the ground, and linguistic and social differences within and across communities in India.This paper will elaborate on our philosophy, methodology, and the design of an approach to tackle complex policy problems in the context of regional planning in South India.
