1
Post-USSR land cover change in Eastern Europe socioeconomic forcings, effects on biodiversity and future scenarios socioeconomic forcings, effects on biodiversity and future scenarios Volker Radeloff University of Wisconsin-Madison Funded by A NEESPI Project
4
Background 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
5
Background 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
6
Background 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
7
Objectives 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
8
Objectives Biodiversity Socio- economics Land cover
9
Approach Current land cover from MODIS data Separating plowed from fallow fields with spectral mixture analysis of MODIS reflectance data Landcover in the study area
10
Approach Land cover change analysis with Landsat TM/ETM+ data 1985 to 2002 data Landsat sample scenes
11
Landsat TM Sep. 2000 RGB: 4,5,3
12
Landsat TM 1985-88
13
Classification based on TM & ETM+ data from 2000 Landsat TM/ETM+ 2000
14
state farms (until 1990) Poland Slovakia
15
Objectives Biodiversity Socio- economics Land cover
16
Approach 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
17
Approach 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
18
Objectives Biodiversity Socio- economics Land cover
19
Approach Wildlife habitat analysis for three species of conservation concern European Bison Saiga antelope Brown Bear Umbrella species for biodiversity Radio-collared bison in the Slovak Carpathians, Dec. 2004
20
Approach Radio-collar locations as input for resource- selection functions Habitat variables include land cover, fragmentation indices, and settlements Saiga with satellite radio-collar
21
Approach Radio-collar locations as input for resource- selection functions Habitat variables include land cover, fragmentation indices, and settlements
22
Approach Bear data is collected from local hunting departments via an ArcGIS server This allows online digitizing of bear activity and easy data transfer Arc/GIS server for bear mapping
23
Objectives Biodiversity Socio- economics Land cover
24
Timeline YearMilestones 2005 MODIS/TM image processing, socioeconomic data collecting, wildlife occurrence data collecting 2006 MODIS/TM image processing, regression LCLUC versus socioeconomics, habitat analysis 2007 Accuracy assessment, future scenarios simulations, journal articles, web page dissemination
