The Human Impacts Database

A collection of useful numbers for quantifying the impacts of the human presence on Earth.

This quantity is a single measurement of the quantity at a given point in time (6000 BC - 2015).


Value:		(2.7 ± 0.9) × 10¹² kg see this value in other units This is equivalent to... (2.7 ± 0.9) × 10⁹ tonnes 27.19 ± 9.03 Pg
HuID:		84302
Relevant Year(s):		6000 BC - 2015
Summary:		The global cumulative sediment produced via accelerated erosion of cropland over the entire period of agriculture (6000 BC — 2015). This does not include sediment movement due to accelerated wind erosion and considers only water-mediated transport.
Method:		This value results from a spatially-distributed erosion model sampled via Monte Carlo methods. Data comes from 14 different studies which report measurements of anthropogenic sediment from catchment basis in different locations with different agricultural histories. Uncertainty represents the interquartile (25% - 75%) of the estimated values.
