The Arequipa Nexus Institute for Food, Energy and the Environment (Nexus Institute) is located in Southwestern Peru, generally bounded by the city of Arequipa to the east, the Majes River to the west, the Pacific Ocean to the south, and the Andes mountains to the north. Though agriculture has been practiced in parts of this cool desert region (MAT~15°C, MAP

Arequipa region is locaed in Southwestern Peru. The Arequipa Nexus Institute for food, energy, water and the environment aims to address the key challenges to a sustainable furture for the people in the region. This roundtable discusses about the sustainable water management, geosaptial analysis and environment sharing, long range sensor network solution for soil health monitoring and data management and sharing in this Nexus project.
Characterizing And Mapping The Field Scale Spatial Variability Of Surface Horizon Soil Properties And Water Content With Noninvasive Em38, Ryan W.R. Schroeder, Robert Austin, Joshua Heitman, Adam Howard
Characterizing And Mapping The Field Scale Spatial Variability Of Surface Horizon Soil Properties And Water Content With Noninvasive Em38, Ryan W.R. Schroeder, Robert Austin, Joshua Heitman, Adam Howard
Purdue GIS Day
The spatial variability of physical soil properties at the field scale is increasingly important in agriculture and natural resource management. Changes in topography, parent material, management practices, erosion/deposition rates, etc. can influence the variability of the soil’s physical properties and help guide management and land use plans. The Geonics EM38 is a noninvasive geophysical sensor which is used to measure the apparent electrical conductivity (ECa) of the soil through electromagnetic induction – primarily influenced by clay content, soil moisture content, and salinity. Soil moisture has been found to be a significant contributor to ECa and is therefore useful in determining …

Using Census Bureau Data For Current And Historical Gis Research, Bert Chapman
Libraries Faculty and Staff Presentations
Provides examples of how geographic information system (GIS) data can be used to conduct historical and contemporary research using Census Bureau data and mapping and other resources. Such data and mapping can enhance understanding of historical and contemporary subjects in a multidisciplinary variety of topics.
Land Use As It Relates To Land Slope, James D. Plourde, Bryan C. Pijanowski
Land Use As It Relates To Land Slope, James D. Plourde, Bryan C. Pijanowski
GIS Day
The goal of this project is to analyze the relationship between the slope of land and agricultural land use. The output was analyzed to determine a threshold point at which agriculture practices drop off in relation to higher slope values. Slope of the land is important to agricultural practices because it impacts drainage and net crop primary production. Agricultural land was extracted from the 2001 National Land Cover Dataset using reclassification tools in ArcGIS 9.3. The slope of the contiguous United States was derived from the United States Geological Survey National Elevation Dataset by using the slope tool in the …
