2. Definition
In-situ slum redevelopment is an urban renewal strategy of physical, social and economic redevelopment of slums, where the residents are allowed to live on the same plot of land after redevelopment.
For the period of redevelopment, however, they are shifted to temporary transit camps close to the site.
In in-situ slum redevelopment, the residents are provided with flats instead of plots.
These projects are generally handled through PPP scheme where a private company takes over the construction process and is awarded a portion of land on site in return.

3. Procedure In-situ slum rehabilitation is a three step process:
Residents move from their current settlement into a temporary housing camp nearby
Private developers raze the slum and begin construction of high-rise apartments on site
The residents move out of the transit camp and into the new apartments in the colony. 

4. Criteria for choosing between Relocation / In Situ Rehabilitation
The slum is in a residential area according to the master-plan
In Situ Rehabilitation is possible since this land can be developed as a residential colony.
20% importance.
More than 80% of the residents work in areas within 3 km radii of the slum
In Situ Rehabilitation is the approach to undertake since this would ensure their ability to earn a livelihood.
20% importance
A house of minimum 25 sq meters is allotted to at least 80% of households living in slum after considering the Floor Area Ratio with a maximum of 4 storeys
In Situ Rehabilitation is possible as the majority of slum dwellers would be taken into consideration.

5. More than 30% of the residents earn their livelihood within the slums
Relocation should be the approach since In Situ rehabilitation will only be feasible if workstations are provided
15% importance
There are concrete plans by the Land Owning Agency to develop/use the land in the next 5 – 7 year
In Situ Rehabilitation is not possible, Relocation should be undertaken since the land owning agency will want to evict the slum dwellers.
10% importance
The slum is less than 20 years old
In this case, in situ rehabilitation would be preferred since the residents have been in the slums for a long period of time.
The ties within the community are fairly strong
This would allow better in situ rehabilitation as the community would function well as a whole.

7. Implementation of In-situ Rehabilitation scheme
The Delhi Development Authority (DDA) decided to take up in-situ development towards rehabilitation of slum dwellers in next five years for 23 clusters in the capital city.
The total numbers of dwelling units of about 25 square meters will be about 47,500.
These will be taken up on public-private partnership (PPP) model in which the land occupied by slum dwellers will be made available to developers, who will construct houses in accordance with the numbers identified by the DDA.
These houses will be constructed in some parts of the area while in the remaining areas the developer will be allowed to carry out commercial exploitation of the land.
This would enable the developer to spill over some of the costs from building the rehabilitation units to the commercial activity, thereby reducing the burden on the slum dwellers as well. This mixed development allows them to get the cross subsidy by way of targeting two different segments of society.

8. Case Study1 KATHPUTHLI COLONY, DELHI
In-situ rehabilitation model is being applied at the Kathputhli colony where residents will have access to 12-storeyed buildings in which the ground floors will be devoted to promoting artistic and commercial enterprise since most of the residents are puppeteers, craftsmen or musicians.
The constructions will house 2,800 dwelling units with a minimum area of 30.5 sqm meant for the colony’s residents.
The site also consists of a separate 2.1-acre commercial space to be developed by private developers and ‘high-category residential apartments’ in 2.4 acres which will help boost the earnings of artisans and craftsmen, according to the DDA’s plans.
Many other public amenities are being constructed on site for supporting the artisans and the craftsmen such as community hall, schools, Basti kala vikas Kendra etc.

10. Case study 2 DHARAVI SLUM, MUMBAI
Dharavi is the largest and one of the most populated slum pockets in Asia housing about a million people.
The approach to be used is in situ rehabilitation with private developers being asked to demolish the low-rise slum and re-house the residents in tower blocks on the same site, rather than moving them out of the city.
Dharavi is right next to a prime office district, and is surrounded by three important railway lines. The companies can use the plum real estate left over after they've built tower blocks, to build lucrative shopping malls and office blocks for the middle classes.
It follows a pure top down planning, with zero participation from the concerned parties in Dharavi.
Each family will be allotted a self contained house of 225 square feet carpet area free of cost in Dharavi.
The developer will bear the cost on account of rent of the transit tenements but the cost of expenditure of consumables like water, electricity, telephone etc. will have to be borne by the slum dwellers.
