The building crane, which has become the most striking feature of the urban landscape in Switzerland, is beginning to alter the mountain landscape as well. Districts of the Swiss Alps, which up to now have consisted of only a few disconnected small communities content with selling cheese and milk, perhaps a little lumber and seed potatoes, are today becoming parts of planned, developing regions. The new highway, the new skylift, the new multi-nationally-owned hotel will diversify the economy and raise the standard of living in the mountain areas, or so many Swiss regional planners and government officials hope. The mountainous area of Switzerland, which accounts for nearly two-thirds of the total area of the country and only 12% of the total population, has always been the problem area. According to the last census in 1970, 750,000 people lived in the Swiss mountains. Compared with the rest of the country, incomes are lower, services are fewer, employment opportunities are more limited and populations are decreasing. In fact, in only one respect do mountain districts come out ahead. They have more farmers, which many people do not consider to be an advantage. 17% of the Swiss mountain population works in primary occupations, in contrast to only 8% of the total population of the country. The mountain farmers are a special breed of men. They work at least twelve hours a day in topographical and weather conditions which kill most crops and which only a few animals will tolerate. About half of them work at some other jobs as well, leaving 'their wives and children to do the bulk of the farm work. In the Rhone Valley in the canton of Valais in south-western Swizerland nearly four-fifths of the farmers commute daily from their mountain farms to the large factories in the valley. In other parts of Switzerland this pattern of life is not as common, but almost everywhere n. on-farm wintertime employment is the rule. With all the difficulties inherent in working in the Swiss mountains, why should anyone resist any extension of the mountain economy? The answer, as Andress Werthemann, editor of the Swiss mountain agriculture magazine Alpwirtschafiliche Monatsblatter states, is that 'when tourism becomes too massive, farming disappears'. And basically there are three reasons why Switzerland needs its mountain farmers: they contribute to the food supply, they preserve the landscape, and they represent the Switzerland of nostalgia and holiday dreams. But in the real world, and especially in highly industrialized Switzerland where mountain farmers are aware of the 'benefits' of city living, is it possible to maintain mountain agriculture and still solve the problems of mountain communities? The Swiss government has come to the conclusion that other kinds of employment in addition to farming must be emphasized. Yet whether it is possible to create other jobs that will not completely destroy agriculture is unknown. The building crane represents ______.
