[In Part 1 of this series, we looked at the ongoing practice of manual scavenging in Bengaluru, even though it was officially banned in 1993. Part 2 delved into the main reason for its continuation, which is the lack of awareness about the operation and maintenance of sewage treatment plants (STPs)] In part 3, we explore the functioning of STPs in Bengaluru and how their effectiveness can be enhanced for both the betterment of the environment and to eliminate manual scavenging.  Why are STPs important?  According to Ananth S. Kodavasal, director at Ecotech, who also formulated the STP guide for…

Chennai has long been guilty of excluding marginalised communities from the scope of its flagship projects such as Singara Chennai. Explaining this historical marginalisation process, the Information and Resource Centre for the Deprived Urban Communities (IRCDUC), in its ‘Urban October Campaign’ says that historically, marginalised communities settled near water bodies in Chennai, as these were the only available lands that were neither in demand nor in possession of affluent communities. Forcibly dislocating marginalised and vulnerable families from their places of habitation to the city margins, without exploring possibilities of relocation near their existing sites of residence, is an act of…

Part 1 and 2 of the series looked at the transformation of Jayanagar from a quaint neighbourhood to a bustling commercial zone.

Figure 3.1 The Transportation network of Bengaluru and transit deserts: The arterial roads connect to other cities i.e., Bellary, Tumkur, Coimbatore, Mysuru  and the Old Madras Road.

Bengaluru was once divided into two distinct centres: An urban settlement and a military cantonment. However, in 1948, the two centres merged together to form Bengaluru city corporation for a new, unified Bengaluru city.  Over the following decades, the city experienced large-scale development of public industries in sectors such as telecom, machinery, electronic goods, etc. It also saw the emergence of a large number of residential layouts, which made it a pensioner’s paradise. One such locality is  Jayanagar neighbourhood, which was laid out in 1949. Characterised by numerous art deco bungalows, abundant parks, playgrounds, an accessible schooling system and a neighbourhood commercial…

Keeping the slum dwellers at the core of its planning, the Slum Rehabilitation Authority (SRA) scheme was initially conceptualised way back in 1995. With about half the Mumbai's population living in informal settlements, the SRA scheme is critical for ensuring better quality housing for all Mumbaikars. The city has about 2149 SRA projects, involving 5,29,434 proposed tenements and 2,49,887 tenements already handed over to people. As we saw in the first part of this series, the buildings are poorly maintained and affecting the not just quality of life but also causing extreme stress to the residents due to various issues.…

The article aims to study a one square kilometer area of Jayanagar in different aspects. It is intended to be a comprehensive essay of the area for planners, designers, sociologists, and residents. It is an analysis of the current scenario of Jayanagar through four different aspects that include setting up historical and spatial context with the city, evolution, street network and land and built use. It provides analyses and inferences to comprehend the growing demand and redevelopment of Jayanagar and how it would further evolve in the coming years.

Mumbai has over 16,000 cessed and dilapidated buildings — some close to a hundred years old — that must be redeveloped. On May 14, 2023, the state government announced that it would constitute a separate authority to push for self-redevelopment of such buildings — a solution to the city’s housing crisis that involves societies of residents living in these buildings undertaking the redevelopment.  Deputy chief minister and housing minister Devendra Fadnavis said the government has set up a particular cell for self-redevelopment to ensure that proposals are approved within three months and deemed conveyance — a significant requirement for such…

Chennai has waited for more than a decade for the completion of the Port-Maduravoyal Expressway project. The infrastructure project was commissioned with a view to decongesting Chennai roads, particularly from traffic from containers that head to the city’s port. The funding agency for the Port-Maduravoyal Expressway project is the National Highway Authority of India (NHAI) which is also responsible for its maintenance and management. Disagreements between successive state governments have resulted in the project lying suspended for an inordinately long period. Over all these years, commuters have been driving past incomplete pillars where the elevated expressway should have been. Shanavas…

Plenty of manuals and guidelines are available that list out various steps to be followed to ensure quality in road construction. The problem is the unwillingness to enforce these guidelines at the time of construction. Just to list some factors which affect the quality of road construction: Inadequate bitumen content in the mix Overheating of bitumen during mixing process Inadequate compaction during construction Stripping of bitumen from aggregates (Aggregates are raw materials that are produced from natural sources , including gravel, crushed stone, and sand. When used with a binding medium, like water, cement, and asphalt, they are used to…
