Check encroachment using IIMB-RERI ‘raja kaluve’ tracker

Bangalureans need to have the survey number, village, hobli and taluk as found in the registration document to be able to use this portal.

The Real Estate Research Initiative of Indian Institute of Management Bangalore (IIMB-RERI), with support from the Bruhat Bengaluru Mahanagara Palike (BBMP), has launched a web-based portal – to enable Bangaloreans to know if their property is situated on a storm water drain or ‘raja kaluve’. Inaugurating the portal for public use, BBMP Commissioner Manjunatha Prasad, said: “This portal enables people ease of access to find details about storm water drains in one place.” Citizens need to have the survey number, village, hobli and taluk as per the schedule in the registration document to be able to use this portal.

“There is a general fear, fuelled by a lack of information, among citizens on whether their properties encroach important water bodies like ‘raja kaluves’. Through this effort, we hope to alleviate some of those fears by making information easy to access for all,” said Professor Venkatesh Panchapagesan, Head of IIMB-RERI. Currently, information on encroachments are available on government websites. “Information is not easily searchable and encroachment details are often provided only in the text embedded within survey drawings released by government agencies,” said Sriram Ranganathan, Product Manager, IIMB-RERI.

IIMB-RERI is collaborating with a citizen initiative,, to provide a Google map based searching capability also for areas where detailed maps are available. Shiv Shankar of Mapshalli said, “Technology enabled solutions are the way forward to solve modern-day urban challenges. We started with mapping of 50 villages around Whitefield. Now, after collaborating with IIMB-RERI, we were able to expand to 350 villages to help citizens using modern technology.”

BBMP Commissioner Prasad lauded the IIMB-RERI effort. “I congratulate IIMB for this exercise and look forward to more collaborative efforts between BBMP and IIMB-RERI,” he said. Urban governance expert Ashwin Mahesh added that such systematic efforts to put government data in the public domain are needed to allow citizens to overcome uncertainty and participate in making a better Bengaluru.

Professor Panchapagesan also pointed out that this is the first of a series of such public service initiatives that IIMB-RERI plans for the empowerment of citizens.

  2. Sunil Raju says:

    many of these lakes and rajakaluves had not existed for decades. It would be good for IIMB to survey actual rajakaluves. In some cases the lakes have been converted to bda layouts what is the purpose of the rajakaluve if the lake is non existent.

  3. IIMB-RERI says:

    Dear Ramesh and Sunil

    Thank you for your comments. Here is our clarification:
    1. This portal is based on surveys identified by the Revenue Department having Raja Kaluves on them . As of now, Orion Mall is not on any survey notified here.
    2. IIMB-RERI does not directly undertake survey on the ground. We’ll pass on your comments to the concerned authorities.

What is the ‘smartness’ quotient of Chennai?

The Smart City Advisory Forum was convened in Chennai only 5 times since 2016, showing minimal participation by elected representatives.

Chennai is among the first few cities to get selected under the Smart City Mission programme in 2016. As many as 48 projects under different categories were taken up under the scheme. With only a couple of projects left to be completed, isn't Chennai supposed to look 'smart' now? The much-hyped Central government scheme, launched in 2014, was envisioned to build core infrastructure and evolve 'smart' solutions that would make cities more livable and sustainable. But, a decade since, the reality on the ground may be a little different. While some of the facilities provided under these projects are under-utilised,…

Scenes from a community walk in Mumbai

When I moved to Mumbai, the city felt extremely 'walkable,' but a walking tour in Dadar broadened my definition of walkability.

When I moved to Mumbai in June 2023 for work, I found myself going for sight seeing to the city's tourist destinations. Though the city appeared to have consistent and wide footpaths almost everywhere, vehicular right of way seemed to be prioritised over the pedestrian right of way. This struck me as very strange, even as I continued to enjoy walking through lanes of Mumbai very much. On one hand, there is excellent footpath coverage, utilised by large crowds everywhere. On the other hand, speeding vehicles create obstacles for something as simple as crossing the road.  "Though Mumbai appeared to…
