Simple technologies can bring down the cost of house construction and enable the poor earthquake victims build their houses within their means.
Chhabilal Acharya’s house reduced to a pile of rubbles in less than a minute when the powerful earthquake stuck his village in Laharepauwa Rasuwa on 25th April 2015. His poultry farm, his major source of income, wasn’t spared either. Acharya (62) and his daughter narrowly escaped from the collapsing house.
He had built the house in 1995.
“I gave up even the smallest indulgences in life to save money for the house,“ he said.
It took him five years to save money for the house as his job at Lagtang National Park would pay very nominal.
He has been living in a temporary shelter since the earthquake. With his poultry farm gone, his family is scarping by on his meagre pension of $101 a month.
Government of Nepal has decided to provide $2778 grant to affected households for building house in three instalments. The house should be compliant to the government approved designs to secure the grant. Chhabilal has received the first tranche ($ 500) of the grant. However, he is yet to start building the house.
“The money is not enough even to prepare ground for foundation and I have no other means to supplement the grant“ he mentioned.
Building simple 3-room brick masonry house costs more than $5000 in his village. Stone masonry buildings are equally expensive as the stones are not available locally.
Chhabilal is planning to take loan from a local money lender by mortgaging all his land at half the value to top on the grant.
Banks don’t accept farm land in the village as collateral. Hence, for people like Chhabilal who don’t have any other fixed assets, the local money lenders are the only resort for the loan. The money lenders rip them off with the exorbitant interest rate.
“If my son does well in life, he will be able to pay the loan and release the land,“ Chhabilal said with misty eyes. He knows he may never get the land back as his son is just 16 years old now.
Two hundred and forty two households in Laharepuawa lost their houses in the devastating earthquake. Only 11 households who are well to do or have family members abroad have built their houses so far. Rest are facing the impossible choice, roof over the head or the land that feed them, like Chhabilal.
However, simple technologies can save them from this predicament and help them rebuild their house within their means.
Cement Stabilised Earth Block (CSEB) is one of such simple technologies. It is a very good alternative to bricks. It can be prepared from a simple mixture of local soil, sand and cement (10%). It costs almost three times less than the brick. Besides, it requires less labour and cement mortar to build a house with CSEB. And, it provides better earthquake resistance as the blocks are interlocking. A CSEB compacting machine costs around $ 7000 including installation and all the accessories. The machine can produce up to 450 blocks per day. The pictures below shows the CSEB production at Kalikasthan, Rasuwa. The enterprise was set up with the support of Practical Action.
Another technology which can save cost is a simple stone cutting machine. It can reduce cost of through stones and corner stones, which are mandatory inthe government, approved stone masonry buildings, by 2 to 3 times. A labour can prepare maximum 6 corner/through stones in a day manually whereas as the machine can produce up to 200 pieces of corner stones.
A simple one story house requires more than 150 corners/through stones, which approximately costs $300, if prepared manually. However, with the machine, the cost can be reduced to $100. The stone cutting machine costs only about $1200.
Practical Action has been promoting the technologies in Nuwakot and Rasuwa districts through a DFID funded project in a small scale.
It is an irony that better-off households are better poised to receive the government housing grant as they can fully comply with the government standards. Poor households, who are solely dependent on the grant, are at the risk of losing it as the grant is not enough to build government design compliant house. The technologies can avert the risk by reducing the cost of building house.
Likewise, the technologies can provide alternative livelihood opportunities to the people in the earthquake affected districts as they can be promoted as the local enterprises. Hence, larger diffusion of such technologies is across the earthquake affected districts is important not only for accelerating reconstruction but also improving livelihood.
