Glazes — for the Self-Reliant Potter : A Publication of Deutsches Zentrum Für Entwicklungstechnologien — GATE. A Division of the Deutsche Gesellschaft Für Technische Zusammenarbeit (GTZ) GmbH

Zentrum fiir Entwicklungstechnologien-GATE -stands for German Appropriate Technology Exchange. It was founded in 1978 as a special division of the Deutsche Gesellschaft fiir Technische Zusammenarbeit (GTZ) GmbH. GATE is a centre for the dissemination and promotion of appropriate technologies for developing countries. GATE defines ,Appropriate technologies" as those which are suitable and acceptable in the light of economic, social and cultural criteria. They should contribute to socio-economic development whilst ensuring optimal utilization of resources and minimal detriment to the environment. Depending on the case at hand a traditional, intermediate or highly-developed can be the ,appropriate" one. GATE focusses its work on the key areas: -Dissemination of Appropriate Technologies: Collecting, processing and disseminating information on technologies appropriate to the needs of the developing countries; ascertaining the technological requirements of Third World countries; support in the form of personnel, material and equipment to promote the development and adaptation of technologies for developing countries.-Environmental Protection: The growing importance of ecology and environmental protection require better coordination and harmonization of projects. In order to tackle these tasks more effectively, a coordination center was set up within GATE in 1985. GATE has entered into cooperation agreements with a number of technology centres in Third World countries. GATE offers a free information service on appropriate technologies fo•r all public and private developll).ent institutions in developing countries, dealing with the development, adaptation, introduction and application of technologies.
