Abstract [en]

The purpose of the study is to describe and analyse, from an innovation diffusion perspective, factors important when using demonstration projects as a tool for introduction of sustainable low cost housing. The study is focused on Ethiopia, a country with big challenges as regards population increase, lack of resources, deforestation, land erosion and a general need for better and sustainable housing, especially in rural areas. The study is furthermore focused on the adobe technology as a more sustainable alternative to the traditional building technology which is very timber consuming. Many attempts have been made to introduce this technology with the use of demonstration buildings. A great part of these attempts have failed, some have been successful. In order to study and discuss important factors in connection with the use of demonstration buildings, a project executed some years ago in southern Ethiopia has been analysed. The study is based on findings collected during and after the erection of these buildings mainly through practical tests, interviews and observations. From a technical point of view this demonstration project was successful. It was possible to develop an appropriate production technology and the result was buildings with a good standard and good function. Experiences up to now indicate a good durability. From an innovation diffusion perspective however the demonstration buildings have not fulfilled their purpose. The impact in the region seems to be very small. The conclusion in the paper is that the reasons behind this failure mainly are: (1) Lack of clear and visible relative advantage in comparison to the traditional building technology. The supply of construction timber in the area in question is still good. (2) Lack of a champion advocating the technology by using the demonstration buildings and thereby giving the message to the society that the technology is valuable and trustworthy. (3) Lack of continuity in the demonstration efforts, as a result of the lack of a champion.
