Annual (1986-2020) land-use/land cover maps at 30-meter resolution of the Tucson metropolitan area, Arizona and the greater Santa Cruz Watershed including Nogales, Sonora, Mexico. Maps were created using a combination of Landsat imagery, derived transformation and indices, texture analysis and other ancillary data fed to a Random Forest classifier in Google Earth Engine. The maps contain 13 classes based on the National Land Cover Classification scheme and modified to reflect local land cover types. Data are presented as a stacked, multi-band raster with one "band" for each year (Band 1 = 1986, Band 2 = 1987 and so on). Note that the year 2012 was left out of our time series because of lack of quality Landsat data....
This dataset includes ten years of emissions and sequestration estimates (2005-2014) in two separate tables, 1) the combustion and extraction of fossil fuels on Federal lands and 2) processes from the ecosystems on those Federal lands. The fossil fuel related estimates include the greenhouse gases carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), and the ecosystems estimates include only CO2. The results are presented by State and year, including the Pacific and Gulf offshore areas in the fossil fuel associated estimates. In addition to total emissions, the estimates are broken into categories by the sector of the economy where the combustion or extraction related emissions occurred or the biologic process...

Soil organic carbon (SOC) is a biophysical parameter, which is also directly linked to above ground land use and land cover (LULC). Currently changes in LULC and variations in SOC often are studied and modeled separately. However, both are conjoined and should be seen as part of a cascading ecosystem framework. This is not only true for SOC but also for other biophysical parameters which are governed by human activities. At a watershed scale, this relationship is exceptionally important and the focus should be towards studying the impact of LULC change on the levels of SOC in spatially explicit terms. To advance knowledge on this front, we studied transformations of LULC, erosion and SOC from the start of settled...

Fragmentation extent of six ecosystem types after European Settlement was analyzed using LANDFIRE data. The ecosystem types includes: Grassland, Shrubland, Conifer, Riparian, Hardwood and Sparse ecosystems. The land use change and fragmentation extents have been analyzed by delineating nine Greater Wildland Ecosystems (GWEs) across NCCSC.

The Desert Landscape Conservation Cooperative (LCC) is a partnership formed and directed by resource management entities as well as interested public and private entities in the Mojave, Sonoran, and Chihuahuan Desert and montane sky island regions of the southwestern United States and northern Mexico. Desert LCC science depends on access to transboundary base datasets. Given the importance of vegetation such as grasslands and riparian vegetation in conservation science, a bi-national, landscape-scale vegetation data layer with classes relevant to Desert LCC research is crucial. One objective of this project is to investigate appropriate methodologies and landscape scales to create a Desert LCC binational land cover...

This file geodatabase includes the 2013 Land Use/Land Cover (LULC) and the Marxan target rasters that were derived from it. For an explanation of why targets were selected and how they were derived, please refer to the report. The Python scripts used to generate the layers are also available via the GNLCC portal.
