News from Shinfield


The first issue of Boiling Point was distributed in the relative calm of last January while both Stephen Joseph and Yvonne Shanahan were overseas with our collaborators. Yvonne and Stephen have been working with Dian Desa on an evaluation survey of their stove programme in three villages in Central Java and Bill Stewart has been carrying out a similar exercise in Sri Lanka on the Sarvodaya Programme. The results of the surveys were analysed and written up as discussion papers for a meeting in London on evaluation studies at which Martin Creeley and Mick Howes of the Institute of Development Studies acted as advisers to help refine the ITDG evaluation methodology. In Sri Lanka it was found that of -199 users interviewed 55% said they used their new stove all the time and an additional 18% said they used it for everything except making tea. Only 19.5% of those interviewed did not use their stove, or used it infrequently. 69% of those who used their stoves most or all of the time had Tungku Lowon stoves. The single most important factor that affects the frequency of use of a stove is the accuracy of construction which suggests that emphasis must be placed on field worker training so that they can build stoves accurately. The results of the Indonesian survey have not all been analysed yet. However it would appear that of 10 households where there was a Tungku Lowon stove, 7 were in constant use and were saving fuelwood. Only 5 of the 10 Katesan type stoves that had been introduced before the Tungku Lowon stoves were still being used.

Stephen and Yvonne also went together to Leuven, Belgium, to the 7th Woodstove meeting hosted this time by Dr. Guido de Lepeleire of the Katholieke Universiteit of Leuven. Stephen Joseph presented two papers, one on dissemination and the other on field testing. It was agreed that Stephen Joseph, Guido De Lepeleire, Tim Wood and Paul Bussman would try and develop a standard procedure for carrying out field testing. A position paper on field testing is being prepared by Stephen Joseph and Peter Dunn of Reading University.

Stephen Joseph paid a short visit to Kenya to meet with the Kenya Clay Stoves Working Group. He was assessing their application to I.T.I.S. for funding for the manufacture of improved clay jikos.

Meanwhile, testing in Shinfield has been continuing. Jon Loose who did the testing of the Tungku Lowon has now moved onto materials testing on extruded clay samples. Peter Young, formerly of the UNICEF Appropriate Technology Centre, Embu, Kenya, has taken over the stoves testing and has been optimising the performance of the Indonesian Tungku Mein Chong stove.



Peter has also built a mould for making mud/clay samples and a rig for thermal cycling and testing them. The test rig is now housed in the new improved Stoves Testing Workshop which has been totally enclosed and now includes a permanent exhibition of mud, clay and metal stoves. Jenny Trussell has been working on a training manual for Sri Lanka based on information supplied by Bill Stewart. She has also been making a series of fired clay charcoal-burning stoves that have been developed in Kenya and which will be tested here in Reading.

Yvonne recently went to Sri Lanka to help Bill Stewart with the second stage of his evaluation survey. She and Bill Stewart are now both back in Shinfield and Bill is working for the Stoves Project as Field Project Officer. He will divide his time between the ITDG collaborators helping them with all aspects of their programmes. Stephen Joseph will not be travelling overseas again for some months due to the recent arrival of his second child Benjamin on April 16.


In December, Ian Grant and Yvonne Shanahan were invited to a meeting in France hosted by the Groupe de Recherche et d'Echanges Technologiques (GRET). Yvonne presented a paper and slideshow on the ITDC stoves programme strategy and our experience in implementing with overseas collaborators. The meeting was attended by representatives of various European organisations concerned with fuelwood, forestry and wood-burning stoves, including Eindhoven University. France is particularly anxious to provide technical support for programmes in the Sahel which will help to reduce deforestation. A public awareness campaign is planned for Paris during the Spring to highlight the near crisis situation for the Third World's primary fuel - wood and there will be another meeting in Marseilles in May.
