A city needs to have an environment that is habitable and conducive with appropriate spaces for people who use the city, while also being resilient in the face of increasing climate risk.
Aspects such as a cities’ air and water quality, quality of the built environment as well as the aesthetic and historic aspects in the city are things we need to look at. However, in the light of increasing disaster risk, managing climate change impact in the light of current urbanisation patterns becomes a key concern, and thus land use planning in a city needs to take this into account.
SDG targets 11.4 (safeguarding cultural and natural heritage) and 11.5 (reducing impacts of disasters, especially floods), 11.6 (air quality and waste) and 11.7 (safe, open and green spaces for all groups) all emphasize that for a city to be sustainable, these aspects need to be considered.

Proper management of land, a scarce resource, can bring about many benefits. This is of great importance especially in urban areas.
It is timely to figure out how land is allocated and being used for what purpose in our cities today. In order to create well planned cities with a futuristic vision, having a better understanding of current land use is imperative.
Land use maps are categorized into 36 sub-categories under two types – built-up and non built-up. The extent of land in each of these sub categories are indicated below.
In all of the cities it can be identified that the higher densities are concentrated in the city centres and the expansion is taken place along the roads. The expansion pattern is shaped by the geography of the surrounding area.
The selection of the area for the urban expansion analysis was followed by several preliminary studies. Initially, the urban index values which was identified using the remote sensing information were studied in the respective municipal areas including a fringe area.
Before selecting interested area for the expansion analysis it should consider following facts
- Municipal boundary
- At least 2-3 km buffer around Municipal boundary
- Rough boundary where the physical urban character disappearing
In the remote sensing discipline, the values higher than 0 represent the built-up areas.The boundary for the fringe area was identified by getting the extent of urban expansion as well as a fine boundary where the high-density expansion become insignificant. The identified boundaries were projected on to the latest satellite images to assure the identified urban index values are in line with the existing building densities.
