Changes in terrestrial carbon storage in the United States. 1: The roles of agriculture and forestry
Changes in the areas of croplands and pastures, and rates of wood harvest in 7 regions of the USA, including Alaska, were derived from historical statistics for the period 1700-1990. These rates of land-use change were used in a cohort model, together with equations defining the…
