Why have city planners encouraged development in Navi Mumbai?

City planners have encouraged development in Navi Mumbai primarily to address the extreme overcrowding and housing scarcity within Mumbai proper. By incentivizing enterprises to relocate across Mumbai Harbor, planners aimed to stem the ongoing immigration of unskilled labor that has contributed to the city's growing indigent and homeless population.1

Additionally, this strategy was paired with a ban on the development and expansion of industrial units within the city limits in an attempt to manage urban density. Beyond residential and industrial decentralization, Navi Mumbai has also become a hub for the city's expanding information technology sector, supported by the development of specialized facilities that offer improved infrastructure. While these efforts have faced challenges in achieving their full intended impact, the expansion into Navi Mumbai remains a key component of regional urban planning to alleviate pressure on Mumbai’s infrastructure and housing market.123
