Three LBA-ECO Land Use-Land Change Data Sets Released
The ORNL DAAC and the LBA DIS announce the release of three data sets from
the Land Use-Land Change teams, components of the LBA-ECO Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA).
- LBA-ECO LC-09 Land Cover Transitions Maps for Study Sites in Para, Brazil: 1970-2001
. Data set prepared by E.S. Brondizio and E.F. Moran. This data set includes classified land cover transition maps at 30-m resolution derived from Landsat TM, MSS, ETM+ imagery and aerial photos of Altamira, Santarem, and Ponta de Pedras, in the state of Para, Brazil. The Landsat images were classified into several types of land use and subjected to
change detection analysis to create transition matrices of land cover change.
- LBA-ECO LC-22 Post-deforestation Land Use, Mato Grosso, Brazil: 2001-2005 .
Data set prepared by D.C. Morton, R.S. DeFries, Y.E. Shimabukuro, L.O. Anderson, E. Arai, F. Esparito-Santo, R. Freitas, and J. Morisette.
This data set provides (1) areal estimates of deforestation events (>25 ha) that were identified from 2001-2004 in Mato Grosso, and (2) the classification of the post-deforestation land use as either cropland, cattle pasture, or not in production in the years after the large deforestation events from 2002-2005.
The data are provided in ESRI shapefile format.
- LBA-ECO LC-08 Ecosystem Demography Model Estimated C, NPP, and Biomass for Amazonia
. Data set prepared by P.R. Moorcroft, G.C. Hurtt, and S.W. Pacala. This data set provides Ecosystem Demography Model (ED) estimates of potential above-ground net primary production (NPP) (kg C/m2/y), potential average live biomass (kg C/m2), and
potential average soil carbon (kg C/m2) for the Brazilian Amazon at 1 degree resolution.
This model predicts both ecosystem structure (e.g. above and below-ground biomass, vegetation height and basal area, and soil carbon stocks) and corresponding ecosystem fluxes (e.g. NPP, NEP, and evapotranspiration) from climate, soil, and land-use inputs.
LBA is an international research initiative under the leadership of Brazil.
The project focuses on the climatological, ecological, biogeochemical, and
hydrological functions of Amazonia; the impact of land use change on these
functions; and the interactions between Amazonia and the Earth system. The
LBA-ECO component, which is funded by NASA, focuses on the question: "How do
tropical forest conversion, regrowth, and selective logging influence carbon
storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable
land use in Amazonia?"
