Rough Giude to Spatial Modeling of Corridors: Driving Variables and Spatial Models Miroslav Honzák Human Dimensions Program CABS CI-Washington DC
An example of a spatial model Parque Estadual da Serra do Conduru Parque Estadual da Serra do Conduru Ilheus Ilheus 5 km 5 km Land cover around Ilheus, Bahia based on Landsat imagery (1997) Dispersed solution (MARXAN solution without an optimization)
Variables driving spatial models Land values Species data Ecological function Environ. incentives plus other cost e.g. plus other data e.g. Conservation Cost per Hectare (OCPH) Environmental Benefit Index (EBI) Human welfare cost Quality of habitat Political process cost Political will Excluded areas Excluded areas
Examples of spatial variables Conservation Cost per Hectare (OCPH) Environmental Benefit Index (EBI) Derived from land cover data Land values
Species based index / conservation cost Parque Estadual da Serra do Conduru Calculate Ratio Conservation Cost per Hectare (CCPH) Environmental Benefit Index (EBI) EBI CCPH Spatial model (e.g., TMARIN, MARXAN)
MARXAN versus TAMARIN model Parque Estadual da Serra do Conduru Parque Estadual da Serra do Conduru Ilheus Ilheus 5 km 5 km MARXAN solution with optimization for shortest boundary (cost $R23m) TAMARIN solution for maximum EBI/land acquisition cost (cost $R23m)
