THE SITUATION OF IRRIGATION AND WATER REQUIREMENTS IN WESTERN EUROPE
Due to statistical reports the mainly watered areas of the various countries are discussed. The structural alterations in agriculture are perceptible also with the use of irrigation. The intensification of farms leads away from the method of surface watering because irrigation by sprinklers can be better regulated.
Though the number of irrigating farms had decreased, the irrigated areas in the total and per farm had increased. As in the more agricultural performed countries surface water out of rivers and lakes still can be used, that isn't possible any more in the industrialized heart of Europe. Here competes the agriculture with the inhabitants and the industry for the ground water reserves. This leads to increasing prices for water, by which the farms are forced to be economical. Rational use asks for specific water supply, a task which is fulfilled by the watering-advisory services. Finally agriculture becomes evident by more expensive, but labour-saving irrigation machines.
It is the purpose of this lecture not to bring details which will be reported on afterwards, but to present a survey and to show some tendencies.
