The INTERREG IIIB CADSES project “Integrated Land Use Planning” (ILUP, 2003 – 2006) is led by the Austrian Ministry of Agriculture, Forestry, Water Management and Environment. Additional partners are Austrian Federal and Provincial Authorities which are competent for water management and regional planning. In an international cooperation with Czech Republic (Moravia basin), Germany (basins of the Danube side tributaries Vils and Rott) and Hungary (Raab basin) an integrated river basin management should be developed and implemented. The main focuses are risk management and prevention of floods through adapted land use. The sub-project of the Federal Institute of Agricultural Economics comprises a regional economic analysis of the river Ybbs basin (side tributary of the Danube) and an evaluation of different functions besides the production of goods and raw materials in the agricultural areas in four reference communities in the river Ybbs basin.
