Geography of control in the industry of the Lyons area Industrial concentration has had up to now harmful consequences on the economic functiuns of the Lyons area, since most of the head offices of the groups are located in Paris or abroad. However the industrial groups themselves are decentralizing their administrative structures, thus inducing a still limited but now negligible geographical decentralization. Hence Lyons is recovering some power in the decision making process at least in the industrial part.

The 1968-1979 period has seen a noteworthy increase of the various urban equipments apt to set up the city of Lyons as a regional metropolis. The office buildings construction has registered a spectacular boom, reaching a total of one million square metres of new floorspace, from which 400 000 mž are located in the new business center of La Part-Dieu. But this growth has generated some difficulties in the adjustment with the progress of the tertiary activities, which was not so important. The presence of a large vacant offices stock has produced as, a consequence, a strong reduction of the office buildings projects.

In urban fringes, the future of agriculture is an outstanding problem. Rural equipments, such as irrigation systems, are often. presented as suitable solutions, on account of the intensification process they promote. With regard to zoning, irrigation is either considered as a means for making use of an agricultural allocation, or an attempt to lead to this • agricultural allocation. The paper, a case study about Millery-Mornant, aims at testing > the actual power of an irrigation system to maintain the agricultural use of land front of, rival strategies concerning land" appropriation (urbanization, quarrying) . It is suggested that an institutional support must be developed, in order that the technical equipment have its full effect.
