The Rural Habitat Program
Focus
Support to delivery of cost effective and energy efficient building products and services for rural and peri-urban communities
Capacity building of micro-entrepreneurs and artisans.
Technical supports from the TARA Nirman Kendra
Facilitating demand creation for eco-housing and eco building products and services through social marketing, government schemes, demonstrations and micro-financing.
A comprehensive model is being put in place at one geographical location - Bundelkhand region in Central India
Rural Housing and Habitat Services
Technology development and dissemination local job creation in the rural construction
sector production and application of eco-friendly
construction in rural areas
Design and construction management enhancing quality and safety of rural
housing stock demonstrating institutional models of
housing delivery at a large scale
Capacity building and awareness creating a large pool of technical and
artisanal human resource to deliver eco-friendly construction in an affordable manner
promoting ecological construction for the masses
Enabling basic need of shelter for rural communities
Habitat for the poor is:
A shelter
Physical and social security
A work place
Social position
Clean and hygienic environment – stability, reduced vulnerability
A means of livelihood
A market for products and services
rural habitat: various perspectives

Pucca : Houses, the walls and roof of which are made of permanent material.
Semi-pucca: Houses in which either the walls or the roof is made of permanent material.
Katcha: Houses in which both the walls and roof are made of materials that needs to be replaced frequently.
Serviceable katcha: Temporary houses, in which the walls are made of mud, unburnt bricks or wood.
Non-serviceable katcha: Temporary houses in which the walls are made of grass, thatch, bamboo, plastic etc.

Challenges today
Ecological Resource crunch
High embodied energy materials – contributing to climate change
Trends towards energy and resource intensity and accelerated by lack of information and promotional support to eco-friendly options.
IAY Target for 11th Five year plan: 2000 million sq.mt. of residential area to be added (BAU) in next 3 years
2000 million metric tons of cement, 14x106 million fired bricks, 300million tones of steel and 2000 million liters of water for basic housing alone.
Rural Construction Sector - characteristics
Construction Industry – Resource guzzling
Energy Intensive
Polluting
In-efficient- wasteful
Unable to provide value to the low-income customer
Job providing
Catalyses economic growth
Profitable economic activity even at small scales
Economic – demand inadequacy
Low levels of income 30% are poor - bpl
40% are landless
26% have less than 1 hectare of land
Unstable income streams 30% of household income is from
crops
Another 30% income is from daily wages
Another 16% from salaries
rural housing – factors limiting delivery
rural housing – factors limiting delivery
Distribution – viability of supply (Nationally) Dispersed Settlements-630,000 villages home
to 790 million people 15% of rural population lives in 20,000 large
villages of >5,000 population -
63% live in villages with 1,000 to 5,000 people
22% live in 390,000 small villages of less than 1,000 population
55% villages connected by All Weather Roads
Materials and Technologies – inadequate supply Packaging for production for very few
technologies
Virtually nil pre-fabrication
Little (TFM) support for MSMEs in this sector
Little promotion or demonstration of new options – state engineers not trained
Building centers – fallen apart, no extension services
Indira Awas Yojna – issues and concerns
Structural and systemic issues Land availability Systems and efficiency of delivery
Management issues Inappropriate targeting Financial leakages
Performance issues Quantity / targets Quality of delivery.
Performance issues
Quantity / targets Performance = fund utilization Translation of funds into assets? No human resource for management?
Quality of delivery Information and knowledge about pucca
construction Adequacy of fund (access to DRI loan?) Availability of materials? Skills? Structural strengthening w.r.t disasters? Ecological perspective ? Integrated services and supports-
technical, financial, social??
Situation Madhya Pradesh, example Tikamgarh
Scale of rural houseless-ness = ~ 45,000
IAY Annual target = 3201 (1481)
Total villages ~ 1000 Villages
IAY target utilization last year = 12%
IAY target = Rs. 382.7L
Estimated housing and basic infrastructure demand annually ~ 6000L
Minimum scale (to satisfy min. houseless-ness) ~ 10- 25,000 units annually
10-25 families per village – 1000 GPs
Human resource - approx. 200- 500 skilled mason days and 400-1000 unskilled worker days per village
Building materials @ approx. Rs. 4 lakh per village
Approx. Rs. 3,20,000 in local area
Local economy component = (70%)
Natural growth potential 400 sft to 1.5 L
– Toilet, bath– Drinking water– kitchen– Space for livestock– Space for storing grain and implements– Working shed (if required)
(guidelines for rural housing in progress by the bis)
Rs. 1.0 to 1.5 L per unit; Rs. 4L – 8L per village annually
Additions and repairs, public buildings - three fold increase at least
Situation Madhya Pradesh, example Tikamgarh
Carbon and resource footprint of typical IAY = 1446MJ/m2 Potential improvement 950 – 500MJ/m2
Materials in a typical IAY house and improvement Bricks = 6500 (5200 – 1000 + Earth
blocks / fly-ash blocks
Cement = 30 bags (18- 20 bags)
Steel= 225 kg (100kg)
Jobs per IAY house 40 skilled masons days
80 unskilled worker days
Response required- looking to the future
Reduce environmental Costs
Introduce cost effective techniques
Reduce costs of delivery – decentralize supply

well laid out development
Where Gaggar Village 40 km from Bathinda
town
Customers low-income – landless families,
Costs Built at Rs. 470/sft.
Model A Public-Private initiative with strengths
of various partners pooled in Can be replicated in both rural and
urban areas with minor modifications.
Cluster housing - Bathinda, Punjab
Plot
Key messages Make delivery viable – social housing must
be seen in the perspective of the overall construction sector in rural areas
Aggregate demand for efficiency – response needs to be seen as a cluster approach- housing cooperatives?
Provide ecological and affordable options - Augmentation of supply and diversity of eco-friendly options have to be introduced
Build capacity for quality construction – train artisans, govt. engineers, supervisors, Panchayats
Link with suitable financing options – savings processes to be linked with credit repayments for housing and toilet loans
Dovetail with other schemes – TSC, IAY, Apna Ghar, NREGS for leveraging resources
Demonstrate…promote… train…support….monitor
