Prakash Kajuri is asset rich but cash poor. The Mumbai courier earns about $6 a day delivering packages in India's most populous city but his home is sitting on land worth about $2 million dollars. Kajuri lives in Dharavi, often described as Asia's biggest slum, where around a million people cram on to what was once a mangrove swamp along railway lines leading to central Mumbai. The slum is the focus of a looming showdown as municipal authorities and developers seek to raze it to the ground and replace it with office towers, luxury apartments and shopping malls. Families that can prove they have lived in Dharavi since 1995 would be entitled to a free apartment in the same area, but the new dwellings would be tiny, just 225 square feet or 20 square meters, about the size of a living room. Not surprisingly, many prefer to stay where they are. “Why should I move into such a small place with my family?” said Kajuri, a father of seven, who has lived in Dharavi for over three decades. “If they want us to move then they should give us the same amount of living space that we now have.” The land on which his nearly 700 square feet shanty stands could be worth at least 100 million rupees in Mumbai's soaring real estate market. “It used to be just marsh and bushes,” said Girish Poojary, a guide who shows groups of curious tourists around Dharavi. “Now builders from all over the world are coming because there's big money here. There's a domestic airport and business parks nearby, so land is very expensive.” Bids to redevelop the roughly two-square-km (0.8 sq mile) warren of brick and corrugated iron rooms into a high-rise housing and commercial complex are due to close by around mid-year. The project is expected to take at least seven years to complete and could eventually be worth up to $10 billion in property sales. The Dharavi project, split into five parts, has drawn 26 bids involving 78 Indian developers including DLF Ltd and Unitech, as well as 25 foreign firms including Lehman Brothers, Dubai World and China's Shimao Group. Nineteen have been shortlisted. “It takes time with these kinds of projects. It's huge,” Ramesh Sanka, chief financial officer for DLF, said in a telephone interview. “But I don't think there'll be any problems, because everyone wants it to happen. Even residents want it.”
