Integrating Biophysical And Economic Models For Assessing Impacts Of Change On Grazingland Ecosystems, J De Souza Neto, J R. Conner, J W. Stuth, W T. Hamilton, J W. Richardson Jun 2024

Integrating Biophysical And Economic Models For Assessing Impacts Of Change On Grazingland Ecosystems, J De Souza Neto, J R. Conner, J W. Stuth, W T. Hamilton, J W. Richardson

IGC Proceedings (1997-2023)

PHYGROW, a hydrologic-based forage simulation model, was parameterized to represent a typical South Texas ranch engaged in the production of cattle and meat goats with an indigenous population of white-tailed deer. Forage production and associated stocking rates for two cattle: goat ratios were simulated for 20 years. Two, ten-year weather scenarios, one representing normal conditions (30% drought years) and one representing dryer weather conditions (50% drought years) were analyzed. Management decision rules were developed for the region to produce estimates of annual animal production and operating cost for the enterprises in each of the four scenarios. These performance and cost …


Semi-Structured Knowledge Models And Web Service Driven Integration For Online Execution And Sharing Of Water Sustainability Models, Luis Garnica Chavira, Jose Caballero, Natalia Villanueva Rosales, Deana Pennington Jun 2018

Semi-Structured Knowledge Models And Web Service Driven Integration For Online Execution And Sharing Of Water Sustainability Models, Luis Garnica Chavira, Jose Caballero, Natalia Villanueva Rosales, Deana Pennington

International Congress on Environmental Modelling and Software

The wide variety in descriptions, implementations, and accessibility of scientific models poses a huge challenge for model interoperability. Model interoperability is key in the automation of tasks including model integration, seamless access to distributed models, data reuse and repurpose. Current approaches for model interoperability include the creation of generic standards and vocabularies to describe models, their inputs and outputs. These domain-agnostic standards often do not provide the fine-grained level required to describe a specific domain or task, and extending such standards requires a considerable amount of effort and time that is deviated from the purpose of producing scientific breakthrough and …


Integrating Socio-Environmental Models: Vegetation, Agriculture, And Landform Dynamics, Miguel Acevedo, William Boyd, Hessam Sarjoughian, Isaac Ullah, Michael Barton Jun 2018

Integrating Socio-Environmental Models: Vegetation, Agriculture, And Landform Dynamics, Miguel Acevedo, William Boyd, Hessam Sarjoughian, Isaac Ullah, Michael Barton

International Congress on Environmental Modelling and Software

How did landscapes evolve as agriculture emerged thousands of year ago? How do we ensure sustainable food production and still maintain environmental quality? Integrated socio-environmental models help provide answers to these two seemingly distant, yet related questions. For practical purposes, in this paper we use the terms socio-ecological and socio-environmental systems, with acronym SES as synonyms. The Mediterranean Landscape Dynamics (MedLand) project aims to develop experimental SES models made possible by recent advances in computation while exercising interdisciplinary collaboration. In this paper, we exemplify one aspect of this integration by discussing the development of a vegetation model, which at the …


Coupling Complex Physical Environmental Process Models With Specific Question-Driven Ecological Models, Tomasz E. Koralewski, John K. Westbrook, William E. Grant, Hsiao-Hsuan Wang Jun 2018

Coupling Complex Physical Environmental Process Models With Specific Question-Driven Ecological Models, Tomasz E. Koralewski, John K. Westbrook, William E. Grant, Hsiao-Hsuan Wang

International Congress on Environmental Modelling and Software

Specific question-driven ecological models often require representation of general physical environmental processes for which complex, widely-accepted meteorological, hydrological, and oceanographic models are available. Although conceptual coupling of physical environmental and ecological models is straightforward, computational linkages often pose insurmountable problems to ecological modelers with limited access to software engineering expertise. Establishing an ongoing dialogue during the course of a simulation between georeferenced physical environmental models and spatially-explicit ecological models can be particularly problematic. We describe a general coupling framework that allows for a modular structure through an intermediate layer between the existing physical models and the custom-written spatially-explicit ecological models. …

Multiplatform Model Integration Framework Of Jrodos - Decision Support System For Off-Site Nuclear Emergency Management, Ievgen Ievdin, Dmytro Trybushnyi, Wolfgang Raskob, Tim Müller, Oleksandr Pylypenko, Oleksandr Mykhalskyi, Mark Zheleznyak

International Congress on Environmental Modelling and Software

Decision Support Systems for off-site emergency management in the case of a nuclear accident should integrate, among others, real-time monitoring systems around a Nuclear Power Plant, regional GIS information, source term databases and geospatial data for population and environmental characteristics. They should comprise state of the art models to simulate the fate of accidentally released radionuclides in air, water, vegetation, and soil to estimate exposure of the population via all relevant exposure pathways. The real-time online decision support system RODOS is being developed under the auspices of the European Commission’s RTD Framework programs since 1992 to achieve the above-formulated objectives. …

Major societal and environmental challenges require forecasting how natural processes and human activities affect one another. Model integration across natural and social science disciplines to study these problems requires resolving semantic, spatio-temporal, and execution mismatches, which are largely done by hand today and may take more than two years of human effort. We are developing the Model INTegration (MINT) framework that incorporates extensive knowledge about models and data, with several innovative components: 1) New principle-based ontology generation tools for modeling variables, used to describe models and data; 2) A novel workflow system that selects relevant models from a curated registry …


An Ontology-Based Design For Modelling Case Studies Of Everyday Proenvironmental Behaviour In The Workplace, Gary Polhill, Nick Gotts, Noelia Sánchez-Maroño, Edoardo Pignotti, Óscar Fontenla-Romero, Miguel Rodríguez-García, Amparo Alonso-Betanzos, Pete Edwards, Tony Craig Jul 2012

An Ontology-Based Design For Modelling Case Studies Of Everyday Proenvironmental Behaviour In The Workplace, Gary Polhill, Nick Gotts, Noelia Sánchez-Maroño, Edoardo Pignotti, Óscar Fontenla-Romero, Miguel Rodríguez-García, Amparo Alonso-Betanzos, Pete Edwards, Tony Craig

International Congress on Environmental Modelling and Software

This paper outlines the design of a model for simulating six case studiesof everyday pro-environmental behaviour in the workplace. Rather than creating sixseparate models, we want to exploit similarities among the case studies andmaximise code re-use – a problem common in the world of integrated modelling.Noting concerns about modular integrated modelling that have been raised bynumbers of authors, we start from a standpoint of viewing integrated modelling as aproblem of semantic integration. A system for integrated modelling using OWLontologies as the medium of representation of the structure and state of the modelat any one time is presented and an early …


Integration Of The Daycent Biogeochemical Model Within A Multi-Model Framework, Jared Abodeely, David Muth, Kenneth Mark Bryden Jul 2012

Integration Of The Daycent Biogeochemical Model Within A Multi-Model Framework, Jared Abodeely, David Muth, Kenneth Mark Bryden

International Congress on Environmental Modelling and Software

Agricultural residues are the largest near term source of cellulosic biomass for bioenergy production, but removing agricultural residues sustainably requires considering the critical roles that residues play in the agronomic system. Determination of sustainable removal rates for agricultural residues has received significant attention and integrated modeling strategies have been built to evaluate sustainable removal rates considering soil erosion and organic matter constraints. However, the current integrated model, comprised of the agronomic models WEPS, RUSLE2, and SCI, does not quantitatively assess the impacts of residue removal on soil organic carbon and long term crop yields. Furthermore, it does not evaluate the …


Integration Of Climate Change Effects In Local Models And Urban Planning Processes, S. Schlobinski, L. Gidhagen, Jonas Olsson, Steven Frysinger, Ralf Denzer, P. Kutschera Jul 2012

Integration Of Climate Change Effects In Local Models And Urban Planning Processes, S. Schlobinski, L. Gidhagen, Jonas Olsson, Steven Frysinger, Ralf Denzer, P. Kutschera

International Congress on Environmental Modelling and Software

Results from global and regional climate scenario modelling predict significant changes in temperature and precipitation during the rest of the century [Kjellström et al. 2011]. Episodes of extremely high temperatures and more intense rainfall will occur more often [IPCC 2011]. Climate change will affect the urban environment and should be taken into account in long term and sustainable urban planning for adaptation to the new climate conditions. The spatial and temporal resolution of available climate models, however, is generally too low for the output to be used directly in urban planning and as input to local models. We will address …

Dles Framework For Spatially-Explicit Simulation Modelling: General Description And Some Exemplary Applications, Maria Bezrukova, Vladimir Shanin, Yulia Khoraskina, Alexey Mikhailov

International Congress on Environmental Modelling and Software

DLES is a component-based framework integrating forest and soil simulation models with discrete spatial and temporal resolution. The task was to create the framework facilitating combination of stand-alone models of different spatial and temporal resolution with spatial interactions into the unified system, replacing models and comparing models against each other. Also, the feedbacks between these models can be implemented. The main features of the suggested approach are: 1) the system of models isn’t a ‘monolithic program’ (single executable file), but is a number of stand-alone modules that can be easily added to the system and removed from it; 2) modules …


Interdependence Of Mitigation, Adaptation And Sustainable Development, D. E. Reusser, Tabea Lissner, Luis Costa, Flavio Augusto Pinto Siabatto, Anselmo Garcia Cantu Ros, Jürgen Kropp Jul 2012

Interdependence Of Mitigation, Adaptation And Sustainable Development, D. E. Reusser, Tabea Lissner, Luis Costa, Flavio Augusto Pinto Siabatto, Anselmo Garcia Cantu Ros, Jürgen Kropp

International Congress on Environmental Modelling and Software

Managing the interdependence of climate mitigation, adaptation and sustainable development requires a good understanding of the dominant sociotechnical and earth system processes that have determined the pathways in the past. Key variables include for example water and food availability which depend on climate and overall ecosystem services, as well as energy supply and social, political and economic conditions. Here we attempt an overview of existing model components and globally available data sources and look for gaps in existing approaches. This overview lies the foundation for building a model at the country level that integrates mitigation and adaptation with the ultimate …


Towards The Integration Of Economic And Land Use Change Models, Hedwig Van Delden, Garry Mcdonald Jul 2010

Towards The Integration Of Economic And Land Use Change Models, Hedwig Van Delden, Garry Mcdonald

International Congress on Environmental Modelling and Software

Although in the past decades several attempts have been made to integrate economic models with land use change (LUC) models, none of them have been fully satisfactory. In this paper we analyse four different integrated models for policy support that include economic and LUC models. We describe several functional forms used to integrate LUC and economic models, highlighting the various strengths and weaknesses of each form, and in turn, suggesting possible pathways for improved integration. Analysing the concepts and underlying assumptions of both types of models show their vast difference. When integrating these models, underlying assumptions and limitations of the …

Thirdly, the paper presents an overview of the framework, relating it to existing modelling paradigms. In the …


Go East: A Residential Land Use Model For The Periphery Of Rome, G. L. Ciampaglia, B. Tirozzi Jul 2008

Go East: A Residential Land Use Model For The Periphery Of Rome, G. L. Ciampaglia, B. Tirozzi

International Congress on Environmental Modelling and Software

In this paper we present a model of urban growth and its preliminary application to acase study of the phenomena of residential development in the setting of the eastern periphery ofRome, Italy’s capital city. The modeling approach we use synthesises the two typical paradigmswidespread in the community of quantitative urban planning: the traditional one, based on cellularautomata (CA), and the (relatively) new one, which is agent-based. In particular, our multi-agentsystem (MAS) is in-between a reactive MAS, with agents carrying out a two-staged decision processin a complex environment, and a model of statistical physics, since we use populations ofagents in order …


Xplorah, A Multi-Scale Integrated Land Use Model, Hedwig Van Delden, E. R. Gutiérrez, Jasper Van Vliet, Jelle Hurkens Jul 2008

Xplorah, A Multi-Scale Integrated Land Use Model, Hedwig Van Delden, E. R. Gutiérrez, Jasper Van Vliet, Jelle Hurkens

International Congress on Environmental Modelling and Software

Processes of land use change and their drivers take place at different spatial and temporal scales. The fact that these processes are very often interacting with each other throughout these scales provides major challenges to modellers. Xplorah is a tailor made Spatial Decision Support System for the three major islands of Puerto Rico. It aims to assess the impact of different scenarios on the development of the island. The system encompasses an integrated set of dynamically linked models working at different scales and incorporating knowledge from numerous disciplines. This paper describes the integrated model as well as its individual components. …

Lake And Climate Models Linkage: A 3d Hydrodynamic Contribution, Luis F. León, David Lam, William Schertzer, David Swayne

International Congress on Environmental Modelling and Software

Under a Canadian Foundation for Climate and Atmospheric Sciences (CFCAS) project, targeted to study the feasibility to link regional climate models with lake models, one of the tasks was to consider such a coupling in large lakes. The objective is to provide detailed information on temperature and circulation distributions of the lake to take into account the spatial variability for temperature and the heat exchange through the water's surface. The major contribution of this work is focused on realistic representation of the heat fluxes and temperature distributions to and from lakes especially during the thermally stratified ice-free periods. This paper …


Integration Of Multi-Scale Dynamic Spatial Models Of Socio-Economic And Physical Processes For River Basin Management, Hedwig Van Delden, P. Luja, Guy Engelen Jul 2004

Integration Of Multi-Scale Dynamic Spatial Models Of Socio-Economic And Physical Processes For River Basin Management, Hedwig Van Delden, P. Luja, Guy Engelen

International Congress on Environmental Modelling and Software

Policy-makers have the difficult task to intervene in a complex human-natural system. Therefore it is not enough to focus merely on the individual processes affecting a region, rather it is necessary to look at the system as a complex integral whole. Many authors have stressed the importance of integrated assessment and model integration, but only few have proposed concrete solutions for the integration of different sub-models and the use of the resulting integrated models in practice. In this paper an attempt is made to cover both topics by means of an example: the MedAction Policy Support System (PSS). This system, …


Diva: An Iterative Method For Building Modular Integrated Models, J. Hinkel Jul 2004

Diva: An Iterative Method For Building Modular Integrated Models, J. Hinkel

International Congress on Environmental Modelling and Software

Integrated modelling of global environmental change impacts faces the challenge that knowledgefrom the domains of Natural and Social Science must be integrated. This is complicated by often incompatibleterminology and the fact that the interactions between subsystems are usually not fully understood at the startof the project. While a modular modelling approach is necessary to address these challenges, it is not sufficient.The remaining question is how the modelled system shall be cut down into modules. While no generic answercan be given to this question, communication tools can be provided to support the process of modularisationand integration. Along those lines of thought …
