Alternative routes to urban density
IIED, collaborating with local partners, embarked on a mission to redefine urban density's role in the lives of low-income groups in Karachi, Bangkok and Kathmandu. The goal was to eliminate the dichotomy between people being displaced to distant peripheries or crowding into substandard living conditions. The project concluded in 2015, leaving a legacy of insights and strategies.

Under the leadership of Arif Hasan, the IIED Human Settlements research group engaged with local partners to identify plot-based planning processes that could help to give low-income residents better access to the benefits, and avoid the costs of, densification.
This work includes case studies from three cities: Karachi, Bangkok and Kathmandu.
Even if low-income households in rapidly urbanising countries can find a place in the city, they often get pushed away as the city develops, land values increase and informal acceptance is replaced with formal rejection.
The project’s findings help show that an inclusive city is one that not only helps to make land available to its growing population, but protects people from involuntary displacement as the city grows, and land values increase.
This requires a planning process that facilitates the densification of low-income neighbourhoods, provided that residents directly benefit.
It also means giving residents the collective capacity to improve their neighbourhoods, and ensuring more security from eviction when investing in improvements.
