Progress 10/01/05 to 09/30/06
Outputs
Objectives: Describe, visualize, and analyze the spatial distribution of soil-landscape patterns utilizing geographic information systems (GIS), spatial modeling, and scientific visualization techniques. Overall goal is to develop a framework for sustainable holistic land resource management providing long-term environmental health and economic profitability. Justification: Ninety percent of Florida's population relies on groundwater resources for their drinking water. According to the Florida Department of Environmental Protection (FDEP, 2002) Florida's aquifer system contains more than 2.2 quadrillion (2.2 x 1015) gallons of fresh water. The states water resources are vulnerable to contamination due to large areas covered with well-drained marine-derived quartz sand overlying porous limestone leaching material rapidly. The thickness of sand decreases seaward of topographic inflections from the last Pleistocene shoreline. Sand is very thin or absent in the southern
extremes of the region. In contrast, sandy material is thick in the northern part of the region. Leaching in Florida's soils is accelerated by humid climate with high precipitation amounts of annually 1,494 mm in the south (Miami) and 1,323 mm in the north (Lake City) (Fernald and Purdum, 1998). Pathways and lag times from surface water to groundwater are short increasing the risk of soil and water pollution. The subtropical climate boasts unique and fragile natural ecosystems such as mangroves and marshes that are not found elsewhere in North America. Stresses imposed on Florida's land resources include rapid urban development with a current population of 15 million and projected population of 20 million in 2020 (FLORIDA FIRST http://floridafirst.ufl.edu/). An agricultural industry, which is more diverse than that of most other states in our nation, with over 250 crops and livestock commodities such as sugarcane, citrus, vegetables, peanuts, tobacco - beef, poultry, dairy. Forests
covering an area of 47% of Florida composed of lowland and upland hardwood stands, oak-pine, natural pine, and pine plantations representing a 7 billion $ industry. Recreation and ecotourism with about 45 million visitations every year. The multifunctional character imposed on land resources combining economic, ecological, and socio-cultural human activities in the same land area causes imbalances resulting in degradation of natural ecosystems. As a matter of fact, Florida is ranked first among all states in ecosystem risk with 9 endangered ecosystems. In short, soil-landscapes in Florida are threatened by multi-user stresses leading to the degradation of fragile natural ecosystems and land and water resources. This CRIS umbrella project integrates emerging geographic information technologies, geostatistical methods, and scaling techniques to address these issues. Overall goal is to develop a framework for sustainable holistic land resource management that preserves and improves soil
and water quality. Impolementation: In the Santa Fe River Watershed various soil properties were mapped to assess soil and water quality. Project results can be found at: http://grunwald.ifas.ufl.edu/Projects/projects.htm
Impacts
This project have had major impact with striking results on soil and water quality resulting in multiple publications and presentations.

Progress 10/01/04 to 09/30/05
Outputs
Water resources are vital to the increasing population in Florida, to preserve natural ecosystems such as the Greater Everglades, and serve the agricultural industry. Ninety percent of Florida's population relies on groundwater resources for their drinking water. Multiple stresses are imposed on water resources including growth of urban areas, non-point source pollution, recreation, ecotourism, and others. The multifunctional character imposed on land resources combining economic, ecological, and socio-cultural human activities in the same land area causes imbalances resulting in the degradation of natural ecosystems. Florida is ranked first among all states in ecosystem risk with nine endangered ecosystems. In short, soil-landscapes in Florida are threatened by multi-user stresses leading to the degradation of fragile natural ecosystems and land and water resources. Specific objectives are to: (1) Investigate the impact of multi-user stresses on aquatic and
terrestrial ecosystems (2) Analyze the spatial distribution, spatial variability and interrelationships of environmental factors to gain a better understanding of natural and human-impacted ecosystems (3) Assess soil and environmental quality in a spatially-explicit context Methods: (1) The application of statistical and geostatistical methods for quantitative soil-landscape analysis, with the purpose of analyzing the spatial distribution, variability, and behavior of soil properties (pedometrics) (2) Development of quantitative spatially-explicit models to assess environmental quality (environmetrics) (3) Geographic information system and remote sensing applications to assess the impact of land use management on soil and water quality
Impacts
(1) Gain better understanding of soil landscape relationships (2) Improve soil and water quality (3) Develop recommendatation to optimize land resource management
