Publikováno v: Netherlands Journal of Agricultural Science 43 (1995)
Netherlands Journal of Agricultural Science, 43, 31-46

Quantitative tools for analysis and planning of land use require descriptions of land use systems, for example to use in optimization models. A static, descriptive formulation of land use systems, called Land Use Systems at a defined Technology (LUST
