Project Work PlanDepartment of Interior USGS GE PES and ENP CESIFiscal Year 2008 Study Work PlanStudy Title: A GIS-Based Decision-Support Tool to Evaluate Land Management Policies in South Florida Overview & Objective(s): The primary objective of the project is to develop an integrated ecological and socioeconomic land use evaluation model (the ecosystem portfolio model, EPM) for DOI resource managers to use to reconcile the need to maintain the ecological health of South Florida parks and refuges with increasing pressures for higher density development in the agricultural lands outside of the Urban Development Boundary in Miami-Dade County. The EPM, a web-enabled Geographic Information System based decision support tool, will integrate natural science, economic, and social information with user preferences to support the Park Service's participation in local land use planning, Park-related land acquisition strategies, and related regulatory decisions in Southeast Florida. In particular, this project makes use of contributions from conservation ecology, landscape ecology, decision science, real estate economics, ecological economics, urban planning, GIS analysis, and web technologies. The web-based EPM will contribute to improved public understanding and awareness of the importance of protecting South Florida habitats and ecosystem functions, as well as the possible externalities associated with upcoming land use decisions. Specific Relevance to Major Unanswered Questions and Information Needs Identified: The project is designed to address the following questions and needs in the DOI Science Plan (2005):
Status: On-going project. Recent Products: 2007 Progress Report and Appendices; 2007 EPM webpage prototype; 2007 draft ecological model results; 2007 land value model results; 2007 list of socioeconomic indicators to be developed in FY08. Products: The Ecosystem Portfolio Modeler (EPM) has three major components: (1) an ecological value model based on ecological criteria relevant to National Park Service and US Fish & Wildlife Service resource management and species protection mandates; (2) a real estate market-based land value model sensitive to relevant land use/cover attributes indicative of conservation and development decisions; and (3) a set of socioeconomic indicators sensitive to land use/cover changes relevant to regional environmental and ecological planning. The current version is implemented for Miami-Dade County, with the protection of ecological values in the lands between the Everglades and Biscayne National Parks as the focus. The first two components have been implemented in the GIS web-enabled prototype interface and the third component is being developed in draft form in FY08 in consultation with the Florida Atlantic University Dept of Urban and Regional Planning. Title of Task 1: Development of the decision framework. Task Summary and Objectives: This task is about collaboratively designing the conceptual decision framework that defines the need and scope for each of the components of the Ecological Portfolio Model web tool. Work to be undertaken during the proposal year and a description of the methods and procedures: This component captures the important relationships between conservation/ development actions and the ecological/environmental and socioeconomic endpoints of interest to decision-makers and stakeholders. This framework will be developed in terms of an ecological value model, a market (hedonic) land price model, and a system of socioeconomic indicators within an interactive web-based GIS environment.
Specific Task Product(s): [List and include expected delivery date(s).] Draft final decision EPM framework will be presented to Park Service managers in January 2008. This draft final design will be refined and integrated into the web-enabled EPM GIS environment during the rest of the fiscal year. Title of Task 2: Develop, refine and implement the EPM ecological value model Task Summary and Objectives: This task is about refining and implementing models for the individual ecological criteria for the ecological value model elicited in consultation with the National Park Service and the US Fish & Wildlife Service (FWS). Work to be undertaken during the proposal year and a description of the methods and procedures: The principal components of Task 2 include our efforts to:
Title of Task 3: Develop suite of socioeconomic indicators for impacts of Miami-Dade land use/cover changes Task Summary and Objectives: This task focuses on the development of a system of socioeconomic indicators sensitive to land use/cover changes, and that are important to consider in land use decision-making. Work to be undertaken during the proposal year and a description of the methods and procedures: The system of indicators will be developed this fiscal year in consultation with researchers at Florida Atlantic University and in collaboration with representative regional land use stakeholders. The system of indicators will be partially implemented this year using available data and models and will be implemented in the GIS web tool next fiscal year. Specific Task Product(s): [List and include expected delivery date(s).] Draft set of socioeconomic indicators and plan for implementation will be presented to Ronnie Best and others in a January 2008 workshop. Title of Task 4: Evaluate and refine hedonic land price model for Miami-Dade County and develop related model to evaluate land development pressure Task Summary and Objectives: This task focuses on finalizing the hedonic land price model for Miami-Dade County, which will be implemented in the GIS-based web tool under Task 5. The hedonic land price model will be used to inform a development pressure model that uses future land use/cover patterns to predict future development pressures. Work to be undertaken during the proposal year and a description of the methods and procedures: An economic value model for land parcels is composed of several factors that comprise total economic value of a particular parcel. One of the factors that included in a ranking of the economic value of a parcel is the estimated market value of that land. Various economic analyses regarding southeast Florida were reviewed in FY07 and it was noted that the economic metrics in use, including non-market economic arguments (community character, infrastructure costs, and flood protection), could be problematic for incorporation into the total economic value component of the EPM. Further evaluation and testing of the non-market impacts is underway and will continue in FY08. The hedonic land price model developed in FY07 will be refined based on these considerations in FY08. This land price model will be used to inform a development pressure model that uses future land use/cover patterns to predict future development pressures. In FY08, we will develop a draft development pressure model for future implementation into the GIS-web tool. This model will enable users to explore different land use change policies and their probable effects on future development pressures. Title of Task 5: Evaluate, implement changes to, and manage the EPM GIS Database, implement Ecological Portfolio Model components in web interface, and evaluate and refine web interface usability and usefulness Task Summary and Objectives: The principal components of Task 5 include:
Specific Task Product(s): [List and include expected delivery date(s).] GIS includes data and user interface(s) to EPM procedures and reports for ecological and economic analysis in South Florida. Delivery Date: Refined prototype, with the updated ecological value model and hedonic land price model implemented, will be presented to the Park Service in January 2008 and the GIS implementation and web interface will be updated based on feedback from this exchange.
