Nightlight

Nightlight

Satellite images of Earth at night based on 2016 cloud-free observations over land mass. The image is divided in to three different resolutions: 0.1 degrees (3600 × 1800), 3 km (13500 × 6750), and 500 m (86400 × 43200).

Relative pesticide exposure

Pesticide.exp

Population density

Pop.dens

Population input data are collated from the 2010 round of Population and Housing Censuses, from 2005 and 2014 data. The input data are extrapolated to produce population estimates for the years 2000, 2005, 2010, 2015, and 2020. GPWv4 is gridded with an output resolution of 30 arc-seconds (approximately 1 km at the equator).
