Since 1950, and increasingly through the 1960s, designers from developed countries tried to help with the design problems of developing societies. They were usually more successful when they lived in the country in question for an extended period and worked closely with local people. During the 1970s developing countries became more independent and able to design for themselves. Little has been written about design in the Third World other than official and conference reports. A seminar in 1975 demonstrated that cooperation between countries, leading to self-help, should replace reliance on ‘international experts’. The most urgent need now is for a breakthrough in alternative energy technology, and this is most likely to come from the Third World.
