Abstract：During the 1990s,the largest changes in land use in the Baltic states ocurred in the agriculturalland sector. The changes can be summarised as the abandonment of arable land and the overgrowing of grasslands with shrubs. Both types of formerly agricultural land become successional old®elds. A national land-use map of Estonia is currently not available. Multitemporal Landsat Multispectral Scanner scenes combining winter, spring and summer data were used to classify land use in Estonia in1990 and 1993. Satellite data discriminated `arable land' and` other,   'but failed  to  differentiate `grasslands currently in use'from `successional old®elds'. One-third of the arable land in use in Estonia in 1990 had been abandoned by 1993. 1998 Elsevier Science B.V. All rights reserved.
