  2. Integrated Modeling of Humans Embedded in Ecological System • Intelligent Pluralism (Multiple Modeling Approaches), Testing, Cross-Calibration, and Integration • Multi-scale in time, space, and complexity • Can be used as a Consensus Building Tool in an Open, Participatory Process • Acknowledges Uncertainty and Limited Predictability • Acknowledges Values of Stakeholders • Evolutionary Approach Acknowledges History, Limited Optimization, and the Co-Evolution of Human Culture and Biology with the Rest of Nature SUMBER: www.iseesystems.com/community/...2008/...Modeling/ISEE_Stella.ppt‎

  7. Model Predictability (different models have different slopes and points of intersection) Data Predictability Ln of Predictability "Optimum" resolutions for particular models Higher Lower (smaller grain) (larger grain) Ln of Resolution SUMBER: www.iseesystems.com/community/...2008/...Modeling/ISEE_Stella.ppt‎

  8. Three complementary and synergistic ways to include humans in integrated models: • As “stakeholders” and active participants in the model conceptualization, development, construction, testing, scenario development, and implementation processes. • As “players” of the models where the model is used as both a decision aid and as a research tool to better understand human behavior in complex valuation and decision processes. • As “agents” programmed into the model based on better understanding of their goals and behavior gleaned through 1 and 2.

  11. The Everglades Landscape Model (ELM) http://ecolandmod.ifas.ufl.edu/projects/index.html The ELM is a regional scale ecological model designed to predict the landscape response to different water management scenarios in south Florida, USA. The ELM simulates changes to the hydrology, soil & water nutrients, periphyton biomass & community type, and vegetation biomass & community type in the Everglades region.

  12. The Patuxent and Gwynns Falls Watershed Model s (PLM and GFLM) http://www.uvm.edu/giee/PLM This project is aimed at developing integrated knowledge and new tools to enhance predictive understanding of watershed ecosystems (including processes and mechanisms that govern the interconnect - ed dynamics of water, nutrients, toxins, and biotic components) and their linkage to human factors affecting water and watersheds. The goal is effective management at the watershed scale. Participants Include: Robert Costanza Costanza, R., A. Voinov, R. Boumans, T. Maxwell, F. Villa, L. Wainger, and H. Voinov. 2002.

  15. Global Unified Metamodel of the BiOsphere (GUMBO) • was developed to simulate the integrated earth system and assess the dynamics and values of ecosystem services. • is a “metamodel” in that it represents a synthesis and a simplification of several existing dynamic global models in both the natural and social sciences at an intermediate level of complexity. • the current version of the model contains 234 state variables, 930 variables total, and 1715 parameters. • is the first global model to include the dynamic feedbacks among human technology, economic production and welfare, and ecosystem goods and services within the dynamic earth system. • includes modules to simulate carbon, water, and nutrient fluxes through the Atmosphere, Lithosphere, Hydrosphere, and Biosphere of the global system. Social and economic dynamics are simulated within the Anthroposphere. • links these five spheres across eleven biomes, which together encompass the entire surface of the planet. • simulates the dynamics of eleven major ecosystem goods and services for each of the biomes SUMBER: www.iseesystems.com/community/...2008/...Modeling/ISEE_Stella.ppt‎
