Challenges and opportunities in mapping land use intensity globally.

Highlights: [•] Global patterns of land use intensity are poorly understood, particularly in the developing world. [•] The multidimensionality of land use intensity should be considered by jointly using input, output, and system metrics. [•] A range of cropland intensity metrics exist, but existing data are often uncertain. [•] Large data gaps remain for grazing and forestry intensity. [•] Research priorities should include first, better integration of satellite-based and ground based data, second, validating and better documentation of datasets, and third, creation of consistent time series.
