大多数第三世界国家把提供廉价住宅问题,列在仅次于粮食生产的优先位置。这些国家(当中有世界上最贫穷的国家)面对大量的住宅问题,不可能作过分要求。第三世界的大多数国家尽管进行得晚,但已开始各种研究计划,要发展一种尽可能利用当地廉价原料建造的住房体系。 Most third-world countries place the issue of providing affordable housing at the top of food production. These countries (among them the poorest countries in the world) face a large number of residential problems and it is impossible to make excessive demands. Most countries in the Third World, despite being late, have started various research programs to develop a housing system that is built using local cheap raw materials as much as possible.
