Topic-Affordable Housing In Megacities



Housing Scenario and Urbanization : India

1. India is undergoing transition from rural to urbansociety.

2. Increasing migration from rural to urban areas.3. Mismatch between demand and supply of sites

and services.4. Disparity between high land costs of constructionand lower incomes leading to non sustainablesituation.

5.Lack of equitable supply of land, shelter andservices at affordable prices.

6. Depletion of resources in construction andnegligence of ecology in design.7. Lack of application of cost effectiveness and

energy efficiency in construction.



1.28% urban population growth (Census 2001).

2.40% by 2020 (Vision 2020 ² Planning Commission).

3. 50% by 2041 (draft Urban India Report).

4.Growing urbanisationhas led to :

a) pressure on the availability of land and infrastructure

b) deterioration of housing conditions of the weaker sections of society

c) increased number of slums and squatter settlements.

Housing Scenario and Urbanization : India



Necessity of Providing Affordable housing

1.Urban population likelyto grow from 285.3million in 2001 to 360million in 2010

2.Nearly 36% of India·spopulation likely to beurbanised by 2005.

3.Employment in servicesand real estates showa sharp rise. Rise in population in last ten years is

Housing Scenario In Larger Cities-Why Affordable Housing-from a developers

perspective.1.Large housing segment largely ignored.

2.Property prices unaffordable for middle income group.

3.Economic slowdown has rendered buyers cautious.

4.Consequently, developers forced to shift focus from

the luxury segment to the middle income housing segment.

5.¶Value for money· has now gained prominence.



Duties Of Various Sections Towards Affordable Housing

Developers Government Financial Institutions1.Use of technology to reduceCost of construction.

2.Use of Incremental Housing Techniques for non metros.

3.Creating awareness among the EWS and LIG to improvestandard of living.

4.Create a win-win situation byeconomies of scale rather than

inflated price points.

1.Creation of a committeewhich fast track reforms inaffordable housing.2.Ensuring Infrastructure andHousing go hand in hand to

faster growth.3.Speeding up the approvalprocess.4.Provide incentives to LIGand EWS to relocate.

5.The population in our metros

keep on increasing manifoldsevery year while planning isbased on historical assumpions.The need is to have flexibleStructural and Design plan.

1.Accord Affordable Housing Projects same status as that of other PPP projects.

2.Ensuring Developers are

protected from volatile shift ininterest rate.

3.Encourage affordableHousing in tier I and II cities.



Achieving Affordability Through Matrix of

1) Appropriate Technology-1.Use of renewable resources for building Materials2.Use of raw materials resources based on waste products3.Efficient use of existing conventional materials by producing factory made(precast)building components4.ndustrialization of housing sector 5.Affordability and sustainability.

2)Public private Partnership-

1.Timely delivery by developers.2.Ease of working by the government.3.Transparency by both the parties.

Construction Cost Savings



Construction Systems in India1.Vernacular systems1.Based on local materials & skills

Refined over centuries2.Calls for fair degree of maintenance & varying degree of durability

2.Conventional systems1.Based on mass produced items having predeterminedProperties2.Modern civil engineering practice3. Lesser maintenance & long durability

3.Industrialized systems1. Based on factory produced components(partial/total)

2. Less labour intensive3. High performance specifications

4 Alternative systems1. Middle of the road approach2. Acknowledges local materials and skills3. Rationalises use to suit specific needs

4. Adopts rational engineering practices5. Cost effective and eco-friendly

Public Private PartnershipPartnership Expectations1.Timely delivery by developers

2.Ease of working by the government3.Transparency by both the parties



Public And Private Partnership in Affordable housing

The public-private partnership can be formally defined as:In these partnerships, private developers, non-profit agencies, and in somecases religious agencies receive some funds or support from the municipal,state, or federal government (or all three, in some cases) in order to build or

renovate and manage affordable housing. This can be used both for rentalhousing and as a means of encouraging low-income home ownership. This isalso an approach that has been used in a number of other countries.

A contractual relationship where a private party takes responsibility for all

or part of a government·s (departments) functions« a contractualarrangement between a public sector agency and a private sector concern,whereby resources and risks are shared for the purposes of delivering apublic service or for developing public infrastructure. (Hardcastle &Boothroyd, 2003, p. 31).



The Scheme of Affordable Housing in Partnership as per National UrbanHousing & Habitat Policy (NUHHP) 2007

1.The Scheme of Affordable Housing in Partnership aims atoperationalisingthe strategy envisaged in theNational Urban Housing &Habitat Policy (NUHHP) 2007,of promoting various types of public-private partnerships ² of the

government sector with the private sector, the cooperative sector, thefinancial services sector, the state parastatals, urban local bodies, etc. ² for realizing the goal of affordable housing for all.

2. It intends to provide a major stimulus to economic activities throughaffordable housing for the creation of employment, especially for the

construction workers and other urban poor who are likely to be amongst themost vulnerable groups in recession. It also targets the creation of demandfor a large variety of industrial goods through the multiplier effect of housing on other economic activities.



Need for PPP in Housing

1.Synergy2.Capitalize and maximise on core domain of respective players3.Scale of Development4.Humongous need for combined capabilities5.Investment Gap Funding 6.Cost spread over project lifecycle in PPP model rather thanbeing front loaded in traditional procurement model7.Improving Quality &Efficiency8.Returns for private players linked directly to efficiency andquality delivery

9.Risk Mitigation10Appropriate allocation between stakeholders11On-Time Delivery12Faster and time approvals, payments also linked to timelycompletion

Role OFNational Housing Bank Towards Affordable Housing

1.A basic human necessity supporting economic activities .2.Second largest employment generator, next to agriculture.3.Has forward and backward linkages with over 250 ancillary industries.4.Every Rupee spent on construction, an estimated 75-80 paise is added

to GDP.5.GOI created enabling Fiscal, Monetary and Legal Environment6.Housing Industry Growth in last 5 years ²

Physical Terms 3.0 % p.a.Financial Terms 30% p.a.

7.Contribution of Housing in GDP is about 6%

8.Percentage of Mortgage Debt to GDP is 8.50% (E) in 2005-06, stillway below China·s (12%), Malaysia (22%), Hong-Kong (40%) and US(65%).

Conference-Affordable Housing-2010



We need to have an integrated framework in whichspatial development of cities goes hand in hand with

improvement in the quality of living of ordinary peopleliving there. An important element of our strategy has tobe slum improvement and providing housing for thepoor««.. The Mission has to walk on two legs of improved infrastructure and improved basic services«..µ
