Previous Govt. Policy
Some In-situ Upgradation
Provision of some basic amenities
Previous Strategy I: Forced Relocation to Outskirts of City
Issue 1: Spatial and social integration into the larger urban community.
Leads to further poverty:
People relocated far from place of work,
additional expense on travel.
Informal employment by other household
members & women stopped, as no high-
income households or commercial hubs in
Children have no future:
Limited resources available for children.
Lack of good quality education
The above often forces people to move
back into an inner city slum - to be closer
to local employment and better amenities.

Issue 2: Current large concentrations of low-income social ‘ghettos’ creating Social Stigma
Large concentrations of
low-income groups in one area:
Leads to “social stigma”, low self-esteem,
segregation, insecurity, dilapidation &
Lack of investment in civic amenities
and basic social infrastructure – these
areas often perpetuate unemployment,
lack of education, crime and very
unsanitary living conditions.

Issue 3: Climatic sensitivity and flexibility to socio-economic needs.
Inferences from Mumbai:
FAR-bonuses (instead of density-bonuses) lead to
developers dislocating the poor from inner cities and
getting undue benefits from subsidized land value sites.
New relocation colonies have extremely bad design which
compromises access to even fundamental amenities like
daylight and fresh air.

Inferences from Gurgaon:
20% reservation of dwelling units for low-income groups – failed to
provide sustainable housing due to illegal allotments and lack of

In-situ Upgradation – is the gradual self-construction or improvement of homes done by
the community themselves with minimal govt. support and through provision of basic social
and physical infrastructure services.
For in-situ up-gradation to happen, residents must be given secure tenure rights such that
they may not be uprooted and relocated at random.
In-situ upgradation may be applied to areas which meet the following thumb-rule criteria:
High density (~600 du/ha)
High % of pucca houses
People have already invested a lot in their homes
Infrastructure is partly or fully existing
No environmental or health hazards exist
Have good amenities, parks & public transport in community vicinity.
In-situ Redevelopment – is the process of redeveloping areas with current slum
settlements where new mixed-use mixed-income communities can be created with a viable
cross-subsidy model, which is a function of local land values, socio-economic needs and
general context of the area. For example, a commercial Mall may not be a viable cross-
subsidizing use of land in an area where the demand may actually be for high and middle
income housing, along with low-income groups. Therefore, a socio-economic study of local
context is critical for decision making.
In-situ Redevelopment may be applied to areas which meet the following thumb-rule
Low density (<450 du/ha)
Is within 1500 M of high-speed Public Transport.
Potential for Area level redevelopment or Urban Renewal and Redensification exists.
No environmental or health hazards exist.
Need for mixing with other income groups and mixed uses.
New Development to Prevent New Slums – is essential so that new population coming to
work and contribute to the growing economy of the city can be provided a range of viable
and affordable shelter options.
Not everyone needs to be provided apartment titles or tenure rights. People are
often seasonal immigrants or short term employees, and therefore a range of shelter
options for the new working population needs to be developed in order to prevent the
sprouting of future slums within the city. Providing dormitories or temporary rented shelter
options as well as high-quality high-speed public transportation is also the sustainable way
of controlling and reducing permanent immigration into the city.:
According to a 2008 United Nations Report, India will see a 26% growth in urbanized
population by 2025.
The Masterplan of Delhi- 2021 provides the following targets for provision of Housing
for Urban poor through Slum & JJ approaches till Year 2011 (page 129):
70,000 units through Redevelopment.
100,000 units through New Housing stock.
Current Govt. Policy
In Situ… Allocation of New Free/ Subsidized
Homes based on Eligibility Criteria:
• Free/ Subsidized Homes are quickly sold off &
31.12.1998 Cut off date Proof
people move back to slums.
• Only 10-20% of current Slum Population is
Below 60 K Household Income “ELIGIBLE”. But where will the rest go??
• Not a sustainable or “realistic” model.
Shelter is a Human Right, not Home Ownership.
Giving People a spectrum of Affordable Shelter Options.
Shelter is a Human Right – Not Apartment Titles.
One Size Does not Fit All –
Give people Options for self-selection.
The goal of our approach to a Slum Free Delhi is that people of all income groups and
various strata of society are given formal + hygenic options for shelter – for living
within, or in the outskirts, or in the various sub-cities of Delhi – based on their paying
capacities and lifestyle choices.
Upgradation of current Shelter conditions to acceptable standards as well as provision of
requisite amount of new housing stock, as per socio-economic context and MPD-2021
targets – would prevent the formation of new slums.
Our approach follows the Guidelines for Slum Free City planning laid down by the latest
Draft by Rajiv Awas Yojna (RAY) for Ministry of Housing & Urban Poverty Alleviation.

Microclimate of shared courtyards:
Grass and trees greatly help reduce heat island
effect and create comfort in open spaces.
However, internal courtyards should not be fenced off as shown above. Courtyards (with permeable paving, instead of
grass) are more usable for children playing , cottage industries, etc. Terraces are also valuable play areas for children.

An “Ideal” Community Layout
1500 M walking
All new or redeveloped high-density radius
housing must be within 1500-2000 M walk/
cycling distance from an MRTS Station.
Housing options must be clustered with
local employment opportunities – both
formal and informal. This includes
proximity to High-income groups to
provide informal employment.
To avoid the creation of large “planned
slums”, New low-income groups must be
integrated in small clusters within mixed-
income mixed-use neighborhoods. This
also allows cross-subsidization of
physical and social infrastructure for low-
income groups. Low income housing

Direct subsidies towards housing cost should not be provided as this is not a feasible and
sustainable model for the city to finance. Moreover, providing subsidized flats only tempts or
induces people to sell or rent them out immediately in order to increase their liquid incomes, and
therefore does not actually solve the housing problem.

Strategies for Efficient and Natural Storm Water run-off
a) Storm water management should be separated
from waste water treatment to reduce pressure on
infrastructure costs required for piping, conveyance Street bio-filtration bed
1) Treat at Source:
and treatment. Use street-swales or raingardens to filter and convey water naturally.
This also helps save on piping cost, while providing additional greenery.
b) A 3-tier approach for natural storm water
management should be followed…. run-
i. Treat at Source – using bio-swales, filtration beds,
raingardens, etc. which can be integrated within the
planted edges of streets. This helps save huge
piping costs. Parks/ Detention
2) Capture and Convey Naturally:
ii. Capture and Convey Naturally – Parks, forests Parks and Open spaces should be multi-used as detention ponds during rainy
seasons, while remaining usable green spaces for the rest of the year.
and residual open spaces should be used as
Detention and Retention ponds during rainy
seasons – to purify and absorb water at source.
iii. Final Treatment - of remaining storm water can
take place at a natural treatment wetland or an
Wetland Detention Pond
3) Final treatment of remaining storm water can take place at a natural treatment
wetland or a conventional facility.
3.3 Recycle and reuse waste Decentralized & use Natural Systems:
Infrastructure must bewater for the larger community, wherever possible.
Recycle and reuse waste locally;
To provide adequate sanitation and systems to deal with waste and sewage, several strategies can be employed for reducing pressure on the sewage
system and improving the environment of the overall community:
Separate the sewage + waste water system from the storm water management system;
• Employ Decentralized Sewage Treatment Systems to recycle upto 80% of Waste water – and reuse it locally.
• Reverse Osmosis can help further treat recycled sewage water to drinkable standards.
If low-income groups are located in integrated high-density mixed income communities, common facilities like bio-gas plants and aerobic/ anaerobic
digesters can be constructed. Biogas thus generated can be used in community kitchens, restaurants, etc. while energy generated from the waste
could benefit the entire community.
