Thanks Shekhar, that was a very useful report in understanding how these
settlements came to be.


 Redevelopment is a highly political process, as is the meaning of the term
 slum, which is often used to indicate a desire to displace poor people and
 demolish their settlements.

 I don't believe our cartography should reflect the view of government or
 builders who seeks to clear and rebuild entire areas to favour certain
 classes. Slums encompass a wide spectrum and continuum of housing
 practices. Most such settlements require upgradation, better services, and
 in-situ development. That's a different debate.


My view of squatter colonies is as a type of urban settlement. As a physical
structure, they exist on the ground, they cover large areas of the city and
are distinctly different in both its physical form and character from a
planned layout. Marking them will help in better understanding the structure
of the city and the relationships these settlements have with geographical
features like water bodies, wetlands, transportation networks, access to
govt services.



 No settlement in Mumbai is unregulated or unplanned, informal housing
 comes up in areas which are marked on plans for other purposes and are
 usurped by local officials and landowners/slumlords. They are highly
 regulated as far as water, sanitation, electricity and other services are
 concerned.

 Maps have their own ethics. I think we should all be careful that our
 desire for transparency does not end up making some people more vulnerable,
 by putting them on the map in the wrong way. That said, I'm very eager to
 map houses, markets, workshops, schools and temples in the wadis, koliwadas,
 gaothans, chawls of Mumbai.


Maps are a tool to understand the earth, and we should keep it that way.

In any case, my interest in the slums of Mumbai came out of curiosity on how
these settlements have grown, where and why. If no one else sees any use of
such areas on the osm server, i can easily move it to a separate layer for
my personal use.

just for reference, we did go on about this before :)

Arun:

 Shekhar, can you list out the different classes (official and non
 official) of such dense settlements which look like slums, what they are
 locally called and their description? These areas are of high interest
 to urban planners, govt bodies, NGO's etc and having them mapped
 appropriately will definitely be a lot of help to different parties.

Here is a study I participated in several years ago on Housing 
Typologies in Mumbai:

http://www.urban-age.net/0_downloads/House_Types_in_Mumbai.pdf

I was hoping someone like you with better knowledge would
 bring this up and propose a more meaningful tag. Replacing tags does not
 require much effort.

It's not about replacing tags, it's the logic of tracing something that 
looks contiguous from the bird's eye but is actually quite a mixed 
environment. These are not even common neighbourhoods where 
place=locality would be appropriate.


 Going by the wikipedia definition of brownfield land
 http://en.wikipedia.org/wiki/Brownfield_land, i did not think it was
 totally inappropriate either.

Yes it is, brownfields are contaminated or former industrial sites which 
are either abandoned or slated for redevelopment. Urban mixed 
settlements in India are entirely unrelated.


My interest is in 'slums' which have
 unregulated and unplanned developments (and have been marked by the
 government for rehabilitation, clearing and redevelopment).

Redevelopment is a highly political process, as is the meaning of the 
term slum, which is often used to indicate a desire to displace poor 
people and demolish their settlements.

It seems that this tag is being used indiscriminately across any
cluster in Mumbai which appear dense, this covers a wide spectrum of
settlements that all look the same from a satellite image.


Hi Shekhar, I wanted to do an analysis of how much area such settlements
cover and was tracing the boundaries of these areas. Since there isn't
any agreed convention, i just continued what an earlier user had done in
south mumbai.

While I am always happy to see more people helping map Mumbai -- there 
are only a handful of us -- I'm opposed in principle to tagging dense 
areas inhabited by 60% of the population as brownfield.
