Carbon Flux to the Atmosphere from Land-Use Changes, in CDIAC Trends Online

This data set consists of data on fluxes of carbon to the atmosphere from land-use changes. Annual estimates of carbon flux, from 1860-2000, are estimated to be from deliberate changes in land use in nine regions of the world: North America, South and Central America, Europe, North Africa and Middle East, Tropical Afria, Former Soviet Union, China, South and Southeeast Asia, and Pacific Developed Region. The methods used to derive this time series of flux estimates are described fully in Houghton (1999, 2002) and other publications (Houghton et al. 1983, 1987; Houghton and Hackler 1995, 1999). The net flux of carbon to the atmosphere from changes in land use from 1850 to 2000 was modeled as a function of documented land-use change and changes in aboveground and belowground carbon following changes in land use. The changes in carbon, with time, following land-use change are specified by region and ecosystem type.
