Decentralising	Bengaluru	Urban -The	Regional	Planning	way Priyadarshini	Sen* Abstract: The	concept	of	region	as	a	method	of	classification	has	evolved	though	two distinct phases reflecting the economic advance from a simple agrarian economy to a complex industrial system. Regions have been classified in different ways. The first phase was dominated by the concept of formal region	defined	according	to	homogeneity,	while	the	second	phase	saw	the development of functional region defined on the basis of functional coherence. We the planners have contradicted our ideologies of maintaining	a	spread	effect	of	growing	cities/poles	that	would	'pull	up'	the rural	extremities;	and	at	the	same	time	try	our	best	to	retain	the	rural	ways of life and activities in order to retreat back to our early styles of living. Bengaluru	has	been	inhabited	beyond	its	carrying	capacity	and	planning	its decentralization activities to	peripheries is	no	doubt ambitious	but raises questions	like	evacuation	issues	of	the	already	settled	communities.
