NTR: slum #266

Open ramonawalls opened 8 years ago

ramonawalls commented 8 years ago

Wikipedia defines a slum as an informal settlement, but I don't think that is consistent with many uses of the word which can include both formal and informal settlements.

The UN Stats Glossary (1997) defines slums as "areas of older housing that are deteriorating in the sense of their being underserviced, overcrowded, and dilapidated."

I prefer the Meriam Webster definition (http://www.merriam-webster.com/dictionary/slum): "a densely populated usually urban area marked by crowding, dirty run-down housing, poverty, and social disorganization"

We need input from UN about how they define the term.

This document is helpful, with definitions and criteria for slums and inadequate housing. Fair warning, it is quite dense.

mark-jensen commented 8 years ago

Currently:

A slum is a heavily populated urban informal settlement with substandard housing in which households lack any one of the following: access to improved water, access to improved sanitation, sufficient-living area, durability of housing, or security of tenure.

Proposal: that we refine the definition wrt to that of inadequate housing SDGIO #51 and possibly informal settlement #265

'slum' = a dense or informal settlement that is composed primarily of inadequate housing.

I believe this handles the case of a single dwelling, such as a tenement, located in a non-slum. The use of a disjunction is not ideal. To be informative, it would require reference to or import of 'inadequate housing'.

Makes sense to import inadequate housing for the purposes of the definition. Is inadequate housing an environmental feature?

mark-jensen commented 8 years ago

@rlwalls2008 Original proposal was that it was a subclass of the requested human dwelling #264.

But further reflection has me wondering. Is inadequate housing a type of dwelling? This is more quality like. Follow up with thoughts at https://github.com/SDG-InterfaceOntology/sdgio/issues/51

No kidding. We need some domain experts here in order to approach finalisation of this.

This sounds good, but we're then committing this class to be aligned to the SDGIO world (and hence whatever official definitions we use there). There is nothing wrong with this, but we should add a comment declaring this so other classes can be created if needed. @mark-jensen @rlwalls2008 - when you create the inadequate housing class in SDGIO, could you please ping me on this issue so I can perform the import? Thanks!

An inadequate human habitation would be more clear label and feature like. Housing sounds more like the placement of people (which can occur autonomously) in some form of shelter. Inadequate housing itself sounds be the placement of people in inadequate houses or shelters.

Consider, however, a dictionary definition of housing: a : shelter, lodging b : dwellings provided for people The "provided" part in b is interesting and somehow aligns with "placement of" in my first take above. a. is basically feature-like though, so there's confounding here. We should just pick a stance and add a comment to declare we have done so.

Sorry, overlooked SDGIO_00010012. We'll be using / updating that class right?

For sure. I can add whatever comments / notes are required to clarify our stance.

Re label change and import into ENVO: are we still thinking it is a subclass of human dwelling, or rather an environmental feature?

Right now its a subclass of dense settlement (ENVO_01000653). I think the logic works there and we should maintain that. human dwelling in #264 can be part of a slum.

I agree with @rlwalls2008 that subclasses of human dwelling should be inferred.
