As of last year, Delhi may have overtaken Mumbai as the country's largest city in terms of population, as per a recent study. For over two decades now, the Census reports have pegged Mumbai as the country's biggest metropolitan area. But two demographers from the Washington DC-based Population Reference Bureau (PRB) have found that if the same definition for measuring the populations of Mumbai and Kolkata is applied to Delhi, then the national capital's estimated population for 2007 is much more.

If all goes well, an ambitious proposal to increase Floor Space Index (FSI) within the 250-metre radius of the BRTS corridor to encourage development along the route, is being planned by the state urban development department. It is proposed that all developers along the 120.5 km of the corridor can get an extra FSI over the existing 1.8 FSI. This increases the FSI to 2.8. The proposal has been forwarded to the Central ministry of urban development for approval and is being simultaneously discussed in the state urban development department over its feasibility.

New research finds fresh evidence that urbanization in the United States threatens the populations of some species of migratory birds. But the six-year study also refutes one of the most widely accepted explanations of why urban areas are so hostile to some kinds of birds.

This report shows the impact of the average African to be low by western standards. But it also reveals that a growing number of African countries are now depleting their natural resources

Daybreak in the city. The brief quiet of the night gives way to the low rumble of cars, trucks and industry, but one sound is notable by its absence.

Hunkering down is the safe option if leaving home is risky, but it's a strategy that could leave you out on an evolutionary limb.

The world now lives in cities. According to the United Nations Population Fund (UNFPA) report released recently, the world population has decisively turned urban. About 3.3 billion people live in urban areas and by 2030 that would increase to about 5 billion. This amounts to more than half of the world's population. The level of urbanisation in India, in comparison, appears much lower. Urban India accounts for about 30 per cent of the total population and its share i s expected to rise to about 40 per cent by 2030. However, the absolute numbers tell quite a different story. At present, the urban population is about 300 million and it is expected to reach 590 million by 2030. Indian cities cannot take comfort from the U.N.'s observation that urbanisation is a positive feature and cities offer the best opportunity to escape poverty. Urban poverty, housing deficit, poor quality of city planning, and weak governance are challenges to be addressed. As of now, the list of unfinished and unattended urban agenda in India is long and daunting. By 2015, about $90 billion needs to be invested in urban infrastructure excluding metro railway projects. But what would be available, on the basis of 2004 figures and projections, is only $10 billion. The national transport policy stresses the need for large investments in public transportation and the need to establish metropolitan authorities that will integrate different modes of transport and promote sustainable options. This still remains a far cry. In spite of a national slum policy and housing policies being in place, the housing deficit in Indian cities is on the rise. In 2007, the housing shortage was about 24 million units and it is expected to touch 26 million by 2012. About 99 per cent of this deficit pertains to lower income groups. The UNFPA report identifies urban governance as the key challenge in planning for quality cities. This appears to be one of the weaker links in the Indian urban context. The Constitution, through its amendments, has devolved more powers to local bodies, but they are yet to be empowered in full. Their capacity needs to be built and financial powers strengthened before we can expect them to adopt best practices in governance. Such issues are even more pressing in smaller cities, which are expected to take most of the growing urban population. Urbanisation may be inevitable but whether it will turn into a positive force or an environmental and social disaster depends on how quickly we put plans and governance in place.
