Urbanisation in India is currently marked by two fundamental trends: lopsided migration to the larger cities and unbalanced regional economic development. In this context, this paper makes a case for the concerted development of small and medium cities as the key focus in the strategy to ensure sustainable urbanisation in India. As cities plan for the long term, among the most critical components they need are the availability of land and the provision of infrastructure and services for a growing population.

The fragmentation of urban landscapes – or the inter-penetration of the built-up areas of cities and the open spaces in and around them – is a key attribute of their spatial structure. Analyzing satellite images for 1990 and 2000 for a global sample of 120 cities, we find that cities typically contain or disturb vast quantities of open spaces equal in area, on average, to their built-up areas. We also find that fragmentation, defined as the relative share of open space in the urban landscape, is now in decline.

This paper presents a strategy for scaling climate change adaptation within urban areas. The strategy specifically focuses on the requirements for mobilizing large amounts of capital for adaptation and other urban risk reduction above and beyond the amounts that will likely be mobilized through new international adaptation funds. The paper, based on a report published by ICLEI–Local Governments for Sustainability, proposes a re-framing of the urban adaptation and disaster reduction challenge.

This paper analyzes the dynamics of population growth and urban expansion in the city of Xalapa, Mexico. It focuses on the establishment of informal settlements, which are one of the many threats to forest and farmland conservation (although these settlements are not the only source of the problem). Spatial analysis of growth data (using Geographical Information Systems (GIS) and statistical modelling) showed that by 2007, 90 per cent of the land area in the municipality of Xalapa had already been altered by human activity.

Understanding the growth dynamics of urban agglomerations is essential for ecologically feasible developmental planning. The inefficient and consumptive use of land and its associated resources is termed sprawl. By monitoring changes in the urban sprawl over a period of time, the impact of changing land use on land, ecology and environment system can be assessed.

Mapping of extent of urban sprawl and by monitoring the temporal changes, the impact of changing land use on land, ecology and environment system can be assessed.

The Bagmati loses its way in Kathmandu amid political vacuum and urban chaos. The chaos and urban sprawl of today’s Kathmandu have taken a serious toll on the stretch of the Bagmati and its tributaries that meet in the city. In the absence of clear guidelines regulating river water use and diversion, the city extracts some 30 million litres of water each day from this seasonal river to quench its thirst, even in the dry season.

The world's urban population now exceeds the world's rural population. What does this mean for the state of our cities, given the strain this global demographic shift is placing upon current urban infrastructure?

It is high time we reversed the processes of
