Slums: a municipal definition
Lately, in the context of my work with Slum Dwellers International, I’ve been thinking about the problems of basic municipal infrastructure — water and sanitation (usually abbreviated W&S) — and along these lines, recently read a terrific paper by Jim Salzman of Duke.

Thirst, a Short History of Drinking Water, chronicles humanity’s earliest efforts to assure clean water and to create rules to distribute it among people. It’s a great paper, about which I’ll have quite a bit more to say in future posts. Meanwhile, if formalizing slums is the greatest demographic issue facing the twenty-first century, and cities are going to be the nexus of intervention and change, then delivery of water and sanitation into established urban environments becomes the most important long-term priority for donor and governmental entities seek to help the global south advance.

I’ve come up with yet another definition, the urbanist’s municipal definition:
A slum is an urban environment where informal housing has outstripped formal utilities
of which water and sanitation is the most primitive and most essential

This definition is consistent with others I’ve proposed:
Slums are spontaneous communities because they are formed by people who choose to move to a place — almost always in search of money income.
Slums are economically rational because they sustain themselves out of a stable set of bargains among tenants (who want to consume as little housing as possible, because that’s all they can afford) and landlords (who want to provide as little maintenance as possible, because that’s how they make money despite low rents).
Slums are a wealth-extraction machine because the effect of under-investment is wealth transfer from the very poor to the landed.
Slums have existed ever since humanity urbanized. We find them in




Mumbai, 2006

What formalizes a slum? Reinvestment in both private space (home improvement) and public space (water and sanitation, usually funded by the municipality).

Not cheap any more!
In each case, somehow the municipal infrastructure was retrofitted into slum neighborhoods.

Since London outgrew its slums, Boston its, New York its, I want to know how those cities retrofitted municipal utilities into slum neighborhoods – because those business models, low tech and small scale as they were, are probably better paradigms than global-north formalized systems. Salzman’s paper echoes what I found in
Basic Model. Public sector funds capital infrastructure as a non-recoverable cost, for some larger civic or political purpose. Thereafter, users pay the (modest) maintenance fees. The basic model even has an insider-outsider twist: insiders (neighbors) get unlimited use via monthly subscription, outsiders are pay-per-use.

Municipal infrastructure, for low-cost water, two millennia old
Basic-Plus Model. As an overlay to the Basic Model, which delivers a group-benefit quality of service (Basic Service), high-end customers can pay bonus fees (the premium) and get higher-quality, more personalized service.
There are eerie parallels with the Basic and Basic-Plus Models when one looks at urban dense-living wi-fi as provided by municipalities, or in a slightly older technology, cable TV and telephony.

Things evolve the same way, don’t they?
The Basic service is – well – basic, and most people pay the Plus premium. One can also see Basic and Basic-Plus Models in, say, metropolitan transport, where subways and buses and trains offer steep discounts to volume users, who are conveniently residents rather than tourists.

Give me formal schooling and clean water and I’ll change the world

Greetings,
I am working with the Margaret Fuller Bicentennial Committee in the Boston area on a display about her life and work which will appear next year in 2010 on the occasion of her 200th birth. As you may know, she was the first female foreign correspondent (working for the New York Tribune) and she traveled to parts of Europe from 1846 to 1850, including London where she wanted to observe, write about, and improve the conditions of the poor. The image you have on your website of London in 1850 would be very helpful. Could you please direct me to the source?
Thank you so much! I’m glad I reached your website to learn about your important work.
Regards,
Bonnie Hurd Smith
