Global drivers

GDP: Global GDP in 1E12 constant 2012(?) US dollar
pop: Gobal population count

National drivers and resources, biodiversity

houssizeAU: Number of household per 100 people in Australia
houssizeCA: Number of household per 100 people in Canada
houssizeCN: Number of household per 100 people in China
houssizeENG: Number of household per 100 people in England
houssizeIE: Number of household per 100 people in Ireland
houssizeJP: Number of household per 100 people in Japan
houssizeL: Number of household per 100 people in Luxembourg
houssizeNZ: Number of household per 100 people in New Zealand
houssizeUS: Number of household per 100 people in USA
meatUS: yearly US meat production in 1E9 kg
domplant: Count of domesticated plants
patentUS: 1E3 number of registered US patents
waterUS: 1E9 liters groundwater withdrawal

peakXprod: A multiple "zoo" time series from 1901 to 2012 containing data on all global renewable, nonrenewable resources (except irrigate area and crop) and meatUS from the list peakXall.

peakXrenew: A multiple "zoo" time series from 1700 to 2012 containing all global renewable resources from the list peakXall.

The only time series starting in 9000 B.C. is domplant, which counts the total number of domesticated plants in year t. The order and categories, in which the data is described, follows Seppelt et al. (2014) to facilitate replication of their work. peakXprod is a subset of peakXall containing data on all global renewable sources and reconstructs yearly extraction of nonrenewable resources and meatUS by using first differences.

For a more detailed description of the variables and their sources, see Seppelt et al. (2014).
