Although various studies have shown that corn ethanol reduces greenhouse gas (GHG) emissions by displacing fossil fuel use, many of these studies fail to include how land-use history affects the net carbon balance through changes in soil carbon content. We evaluated the effectiveness and economic value of corn and cellulosic ethanol production for reducing net GHG emissions when produced on lands with different land-use histories, comparing these strategies with reductions achieved by set-aside programs such as the Conservation Reserve Program (CRP). Depending on prior land use, our analysis shows that C releases from the soil after planting corn for ethanol may in some cases completely offset C gains attributed...
Aquatic Planning Units are derived from the U.S. Geological Survey (USGS) National Hydrography Dataset (NHD)+ v. 2 catchments. They contain information used throughout the NatureScape (landscape conservation design) development. The tables include summaries of information within each catchment including predictor variables. See SI.
Chihuahuan Desert landscapes exemplify the ecological conditions, vulnerability, and management challenges in arid and semi-arid regions around the world. The goal of the Jornada Basin Long Term Ecological Research program (JRN LTER) established in 1982 is to understand and quantify the key factors and processes controlling ecosystem dynamics and patterns in Chihuahuan Desert landscapes. In collaboration with the Jornada Experimental Range (USDA ARS), studies initiated in 1915 have been incorporated into the JRN LTER program. Previous research focused on desertification, a state change from perennial grasslands to woody plant dominance that occurs globally. Based on findings from growing long-term databases, the...
These datasets are products of Phase II of the Appalachian Landscape Conservation Cooperative’s (LCC) landscape conservation design (LCD) created by Clemson University as part of the LCC-funded project, “Interactive Conservation Planning for the Appalachian LCC”. The Appalachian NatureScape Design incorporates and models newly developed data and information from all Appalachian LCC funded research projects as well as key existing datasets from partners to produce a series of maps that integrate aquatic connectivity with terrestrial significant habitats to guide conservation planning and decision making.Conservation Planning, a process of spatially identifying and prioritizing lands and waters important for functioning...
