  • UN Habitat reports that (

    – 1.1 billion people live in inadequate housing conditions in urban areas alone

    – In many cities of developing countries, more than half of the population live in informal settlements, that can be described as life and health threatening

    – Among an estimated 100 million homeless people around the world, available data suggest that increasing proportions are women and children.

    – The annual need for housing in urban areas of developing countries alone is estimated at around 35 million units (during 2000-2010).

    – In other words, some 95,000 new urban housing units have to be constructed each day in developing countries to improve housing conditions to acceptable levels.

    Why the programme is significant?

  • How does bamboo help? • Timbers are getting scarce, inaccessible and expensive • Other building materials are less affordable to poor and

    environmentally less friendly

    • Bamboo - due to its versatile characteristics - offers solution of above issues -

    • It is cheaper (generally $1 or less per culm), durable (if treated properly) and environmental friendly (easily renewable and grows widely)

  • Why INBAR on Bamboo Housing? • INBAR is an only international organization

    mandated for bamboo development

    • Aims to use bamboo in varieties of ways for poverty alleviation and economic development

    • Aims to work in the line of the goals of UN Habitat and Millennium development

  • INBAR’s mission on Bamboo Housing

    • To contribute to MDG 1,2, 7 – to contribute to poverty alleviation, – increase access to primary education and – improve the lives of slum dwellers with an

    environmentally sustainable development

    • To contribute to the aims of UN Habitat – shelter for all – housing right

    • To work mainly on social housing for poor and disaster management

  • Housing activities New experience for INBAR working in

    housing sector. It aims ….. • to collect all the existing knowledge on bamboo

    housing • to transfer knowledge from one region to other

    through training, workshop, publications and demonstration projects

    • to develop innovative techniques and system through action research and development

    • to develop networking

  • INBAR activities so far….

    • Workshops • Hands- on training in Asia, Africa and Latin

    America • Network developing • Web site

  • For more information -

  • Some Experiences

  • • First INBAR Learning on bamboo housing • Partners: UNIDO/BAMTEC • 30 participants from different countries • Hands-on training • Architects from Colombia and Ecuador were

    resource persons


  • A Colombian architect- Sharing experiences

  • Participants eager to learn

  • Building on progress - practical session

  • Structure

  • Participants built the house

  • Workshop output- A complete house

  • Bamboo School and Housing Workshop

    Kumasi - Ghana

    Feb-March 2003

  • Objective of the project

    • To demonstrate the use of bamboo for the construction of public infrastructures such as school, clinic

    • To build local capacity on bamboo housing

  • • Construction of a bamboo school (primary school of 3 rooms)

    • 5 days workshop on bamboo housing - 30 participants from different institutions

    • Partners: TRADA -UK, British High Commission, Accra and BRRI - Kumasi

  • Bamboo preservation

    • Poles were treated with Creosote Oil • Bamboo strips were treated with 3% Boron


  • Creosote Oil- Injection

    • Creosote is a inflammable poisonous chemical

    • Highly effective and cheaper

    • not available everywhere • should not be used for

    exposed bamboo parts • recommended for poles

    only if injected properly

  • • Each internode of dried poles were drilled for injecting the creosote oil

  • Injecting creosote oil

  • Strips in Boron solution

  • Foundation

    Rods are placed in 1.5 meter apart to fix bamboo poles later

  • Structure on progress

    Grids with bamboo strips are made in 15x 15 cm

    Swan timber was used for wall plate to hold the bamboo poles

  • Prefabricated bamboo trusses

    Trusses were prefabricated. Joints were made with gusset plates

  • Cement plastering of bamboo wall

    Chicken mess was used to support cement plaster.

  • Almost complete

    Total wall thickness is 5cm

  • The school…….

  • ……and the hopes

    Furniture are also made from bamboo

  • Housing workshop for dissemination

  • Workshop brought attentions

  • Workshop participants wanted to do by themselves

  • Bamboo preservation

    Glove is recommended

    Inject 20-50 ml of oil in each internode depending upon internode length

    Same system as shown in Ghana case - with creosote oil and boron

  • After boiling 24 hours


    Bases of the poles were boiled in creosote. This part will go underground

  • Strips in Boron solution

  • Bamboo poles

    Bamboo poles are embedded in the foundation

  • Bamboo grid wall with cement plaster

  • Almost complete

  • Workshop participants

  • Ecuador -

    Village capacity building for bamboo housing
