The Ujjain–Indore Metropolitan Region (UIMR) has been expanded to cover more than 16,000 sq km, making it larger than Mumbai, Bengaluru and Pune individually, according to Unify Planning. The redefinition of the metropolitan boundary increases the geographic scale of the planning region and elevates its profile among India’s urban areas. The enlargement reflects a drive to integrate peripheral towns and rural hinterlands into a single metropolitan framework for coordinated development.

The expanded footprint will require revisions to statutory plans and reallocation of resources to meet diverse local needs. Municipalities and district administrations within the UIMR will need to align zoning rules, land use policies and service delivery mechanisms to ensure consistency. Planners noted that harmonising transport corridors, utility networks and spatial planning instruments is essential to avoid fragmented growth and to support efficient movement of people and goods across the enlarged region.

Economists and urban designers said the larger metropolitan area could attract greater investment in housing, commerce and industry, but warned that benefits would depend on timely infrastructure upgrades. Water supply, sewage management and solid waste systems will require scaled planning and financing to meet higher demand. Transport planning, including radial and orbital connectivity, will be a priority to reduce congestion and to connect employment hubs with residential zones across the expanded territory.

Governance arrangements will need to be reviewed to provide a unified vision for growth and to allocate functions across local authorities. Policymakers must consider phased implementation, fiscal transfers and capacity building to enable consistent service standards. The planning community urged inclusion of sustainability criteria and disaster resilience in revised master plans to safeguard long-term liveability as the UIMR transitions to its enlarged form.
