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 (2013-2017).


Value:		≈ 4.4 × 10¹¹ m² see this value in other units This is equivalent to... ≈ 4.4 × 10⁵ km² ≈ 4.4 × 10⁷ Ha
HuID:		23616
Relevant Year(s):		2013-2017
Summary:		Value comes from the FAO Geo-referenced Database on Dams and represents the sum of reservoir areas for all dams specified as used for the generation of hydroelectricity.
Method:		FAO acquires information on dams by self reporting by countries on dam location, height, use, reservoir capacity, and reservoir area. We only used dams specified as used for hydroelectricity. They do not provide a statement on uncertainty, however, there are some missing values for reservoir area in their data.
