BackgroundBackground
Rapid land cover change in Eastern European since the breakdown of the USSR
Widespread agricultural abandonment followed by conversion to shrublands and forest
Agricultural area change from 1991 to 1997; USDA

BackgroundBackground
Socio-economic trends differ markedly among neighboring countries with similar ecological conditions
Change in nighttime lights 1993-2000. Yellow/red: more lights, blue: fewer lights, NOAA-NESDIS

BackgroundBackground
A ‘natural experiment’ in Eastern Europe allows to test hypotheses on the relative importance of environmental versus socioeconomic factors as controls and forcings of land cover and land cover change and thereby on biodiversity

ObjectivesObjectives
Monitor land cover and land use change (LCLUC) in Eastern Europe
Examine socioeconomic and political changes as forcing functions for LCLUC
Examine effects of LCLUC on biodiversity Simulate future LCLUC scenarios and examine
potential biodiversity effects

ApproachApproach
Regression analysis to identify forcing and controls of LCLUC
Socioeconomic variables GDP, land ownership, urban markets,
employment, population, housing, and households, agricultural statistics, “country”
Environmental variables Climate, topography, soils
![Page 17: Post-USSR land cover change in Eastern Europe](https://reader035.vdocuments.us/reader035/viewer/2022062408/56813868550346895da016fb/html5/thumbnails/17.jpg)
ApproachApproach
Hypothesis: Agricultural abandonment is controlled at broad scales by national economic and political conditions, and by climate patterns,and at fine scales by distance to urban markets, distance to major roads, topography, and soil quality
