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.

Abstract [en]

One of many serious problems in Ethiopia today is the rapid pace of deforestation. This accelerates fire-wood shortage and put a high stress on the natural resources including timber for construction. Based on the assumption that low cost housing based on soil is an economically viable and environmentally sound choice, a research programme at Halmstad University was initiated in 2004. This research, aiming at the Kambaata Region in Southern Ethiopia, has focused on the introduction of adobe technology and cement stabilised soil block technology.

A final stage of this research programme is to erect demonstration buildings. Its objective is to demonstrate new building technologies and to use the demonstration buildings as reference objects in studies regarding building technique and attitudes towards these new technologies.

This paper is focused on the role of demonstration projects at the introduction of sustainable low cost housing. As an introductory background some executed demonstration projects are described and their impact is analysed. Against this background, a currently executed demonstration project is described.

Abstract [en]

One of the most serious problems in Ethiopia today is the rapid pace of de-forestation. The consequences are well-known: soil-erosion, shortage of fire-wood and, to a certain extent, lack of timber for construction. In Ethiopia some of the most durable indigenous species have been almost eradicated due to de-forestation.

Against this background a research project named “Sustainable Low Cost Housing – needs, possibilities and attitudes. A project with focus on the Kambaata Region in Ethiopia” has been initiated at Halmstad University. The aim of the project, which is interdisciplinary, is to develop and introduce a new low-cost housing technology and to analyse attitudes towards low-cost housing. This project has been preceded by a pre- study which forms the basis for this paper. The aim of the pre-study was mainly to gather necessary information on which the planning of the major project could be based

One of the main conclusions of the pre-study is that developing a new technology alone is not enough. An introduction of a new technology must take societies’ attitudes into account, if it shall be successful. This can be done by an active and systematic awareness building. This, in its turn, must however be based on further research about attitudes towards low-cost housing technology.
