title: Biodiversity impact assessment considering land use intensities and fragmentation

description: The data provide supplementary information for the paper entitled "Biodiversity impact assessment considering land use intensities and fragmentation".
 
Coverage of the characterization factors

5 species groups: plants, amphibians, birds, mammals, and reptiles
5 broad land use types: cropland, pasture, plantations, managed forests, and urban areas
3 land use intensities: minimal, light, intense (sometimes, intensity levels had to be merged because the data did not allow to differentiate between them)
825 terrestrial ecoregions of the world (according to WWF / Olson et al. 2001)
 
Files
Main data

CF.csv: characterization factors (CFs) for ecoregions and 5 species groups
Taxonomically aggregated data

CF_kingdom.csv: CFs aggregated from 5 species groups to plant and animal kingdoms
CF_domain.csv: CFs aggregated from plant and animal kingdoms to the domain of Eukaryota
Spatially aggregated data

CF_country.csv: CFs aggregated from ecoregions to countries
CF_global.csv: CFs aggregated from ecoregions to the globe
Taxonomically and spatially aggregated data

CF_kingdom_country.csv: CFs aggregated to countries and plant and animal kingdoms
CF_domain_country.csv: CFs aggregated to countries and the domain of Eukaryota
CF_kingdom_global.csv: CFs aggregated to the globe and plant and animal kingdoms
CF_domain_global.csv: CFs aggregated to the globe and the domain of Eukaryota
 
Units
CFs for land occupation: PDF/m2
CFs for land transformation: PDF⋅yr/m2
 
Columns

realm: 2-letter code to identify one of 8 biogeographical realms
biome: ID to identify one of 14 biomes
eco_id: ID to identify the ecoregion, combining numbers for the realm, biome, and ecoregion within each biome nested within each realm
eco_name: ecoregion name
species_group: species group
kingdom: kingdom as a taxonomic rank
habitat_id: ID to link to the land use type and intensity as used in land_use.tif. An ID with .5 represents a merged land use class considering the two habitats with the IDs when rounding the value both up and down.
habitat: land use type and intensity
CF_*: characterization factor
*_occ*: land occupation
*_tra*: land transformation
*_avg*: average approach
*_mar*: marginal approach
*_reg: regional relative species loss
*_glo: global relative species loss
*_rsd: relative standard deviation as a measure of spatial uncertainty due to aggregation (only concerns country and globally aggregated CFs)
quality_*: data quality, distinguishing between original estimates and the use of proxies
objectid: object id of the country
iso3cd: iso3 code of the country
romnam: romanized name of the country
m49code: M49 code of the country, a standard code used by the United Nations
weighting: aspect based on which the CFs were weighted (only concerns globally aggregated CFs)
 
Data quality

original: original estimate (for globally aggregated CFs: mostly original estimates, proxies only considered in areas with current land use)
proxy_intensity: intensity level was missing; CF was derived from another CF of the same ecoregion and land use type but different intensity level and scaled to the right intensity level
proxy_type: land use type was missing; CF was derived from the average regional CFs for light use in the same biome and the ecoregion-specific GEP and scaled to the right intensity level if needed
proxy_gep: global extinction probability (GEP) was missing (only concerns CFs for global relative species loss); GEP estimated based on average GEP per area unit in the same biome and the ecoregion area
proxy_partial: some species groups were missing but not all (only concerns taxonomically aggregated CFs); aggregation done based on partly original estimates and partly proxies
proxy_neighbours: country was missing (only concerns country-aggregated CFs); values were estimated based on the average of the three nearest neighbouring countries
proxy: proxies were considered even in areas without current land use (only concerns globally aggregated CFs)
Note: proxies in country-aggregated CFs apply to at least one of the ecoregions overlapping with the country and not necessarily all ecoregions
