Controlling area based subsidies by remote sensing and building decision support systems based on agricultural registers

摘要

In 1992 the European Union's agricultural policy (CAP) was changed; the subsidies of production were replaced by area based subsidies. This led to the construction of a control system based on a national register of agricultural information (GLR/CHR) and a field block map, both managed by the Danish Ministry of Food, Agriculture and Fisheries. This register stores among other things the yearly claims for subsidy from more than 60.000 farmers, information on husbandry and fertilization etc.. In 1996 this control system was taken into use for the first time. The Remote Sensing Unit at DIAS has since 1992 performed a part of the control of the area based subsidies by remote sensing. After 1996, new digital topographic information became available, which changed and improved the used techniques. This paper describes how the control of the agricultural crops is performed using these new opportunities and the utilization of the new register by decision support systems.
