Recent national conference findings expose massive under-utilisation across sectors. Central Public Sector Undertakings alone hold 10 lakh acres of unused land, excluding Defence and Railways. Combined with state holdings, religious institutions, and private industries, this hidden inventory could transform India's development. Remarkably, the nation's 20 million home shortage could be addressed with just 50,000 hectares, a fraction of available unused land. The core problem is rigid land use policies. Once land receives industrial or specific-purpose designation, it remains locked in that classification even when facilities close or relocate. Enabling land use changes without ownership transfers could unlock countless dysfunctional parcels for affordable housing and social infrastructure.
