Knowledge Discovery For Biodiversity: From Data Mining To Sign Management, Noel Conruyt, David Grosser, Régine Vignes Lebbe Jul 2012

Knowledge Discovery For Biodiversity: From Data Mining To Sign Management, Noel Conruyt, David Grosser, Régine Vignes Lebbe

International Congress on Environmental Modelling and Software

Knowledge discovery from data in environmental sciences is becomingmore and more important nowadays because of the deluge of information found indatabases of digital ecosystems, coming altogether from institutions and amateurs.For example in biodiversity science, all these data need to be validated byspecialists with the help of Intelligent Environmental Decision Support Systems(IEDSSs), then enhanced and certified into qualitative knowledge before reachingtheir audience. Data mining through classification or clustering is the dedicatedinductive process of grouping descriptions based on similarity measures, thenbuilding classes and naming them. Later, the formed concepts can be reused foridentification purpose with new observations. The problem is that when …


Assessing The Vulnerability Of Human And Biological Communities To Changing Ecosystem Services Using A Gis-Based Multi-Criteria Decision Support Tool, Miguel L. Villarreal, Laura M. Norman, William B. Labiosa Jul 2012

Assessing The Vulnerability Of Human And Biological Communities To Changing Ecosystem Services Using A Gis-Based Multi-Criteria Decision Support Tool, Miguel L. Villarreal, Laura M. Norman, William B. Labiosa

International Congress on Environmental Modelling and Software

In this paper we describe an application of a GIS-based multi-criteria decision support web tool that models and evaluates relative changes in ecosystem services to policy and land management decisions. The Santa Cruz Watershed Ecosystem Portfolio (SCWEPM) was designed to provide credible forecasts of responses to ecosystem drivers and stressors and to illustrate the role of land use decisions on spatial and temporal distributions of ecosystem services within a binational (U.S. and Mexico) watershed. We present two SCWEPM sub-models that when analyzed together address bidirectional relationships between social and ecological vulnerability and ecosystem services. The first model employs the Modified …

Near-Real-Time Global Biomass Burning Emissions Product From Geostationary Satellite Constellation, Xiaoyang Zhang, Shobha Kondragunta, Jessica Ram, Christopher Schmidt, Ho-Chung Huang

GSCE Faculty Publications

Near-real-time estimates of biomass burning emissions are crucial for air quality monitoring and forecasting. We present here the first near-real-time global biomass burning emission product from geostationary satellites (GBBEP-Geo) produced from satellite-derived fire radiative power (FRP) for individual fire pixels. Specifically, the FRP is retrieved using WF_ABBA V65 (wildfire automated biomass burning algorithm) from a network of multiple geostationary satellites. The network consists of two Geostationary Operational Environmental Satellites (GOES) which are operated by the National Oceanic and Atmospheric Administration, the Meteosat second-generation satellites (Meteosat-09) operated by the European Organisation for the Exploitation of Meteorological Satellites, and the Multifunctional Transport …


Representing Heritage And Loss On The Brittany Coast: Sites, Things And Absence, Maura Coughlin Jul 2012

Representing Heritage And Loss On The Brittany Coast: Sites, Things And Absence, Maura Coughlin

English and Cultural Studies Journal Articles

This is an essay about the interplay of objects, art and visual culture in several community museums and historical sites dedicated to local social history in coastal Brittany. There, in the later nineteenth and early twentieth centuries, Breton maritime culture invented a range of compensatory ritual objects, sites and practices to account for loss of life at sea. The presentation of this material culture of mourning in small museums, regional museums and ecomuseums on the Breton North Coast and the islands of Sein and Ouessant are examined in this essay. These material objects once bore material witness to crucial moments …

Community Mapping: Transforming Thinking And Actions Toward Sustainability, Melanie J. Kornis

Professional Projects

This phenomenological study explored the level of concern regarding issues of sustainability, for individuals residing within one mid-sized Midwestern urban community. Ultimately, this research sought to determine those factors that increase the sense of urgency for some individuals to do more to reduce our global footprint and to create a sustainable future for our children and grandchildren. The participants were chosen via purposeful sampling and the interview process was used for data collection. Several themes uncovered in the study findings were similar to those in the literature review, which include: caring for the environment, making connections within the community, recycling, …

Representation Of Environmental Dynamics In Models Of Socio-Environmental Systems, Joerg A. Priess, Christian Schweitzer Jul 2012

Representation Of Environmental Dynamics In Models Of Socio-Environmental Systems, Joerg A. Priess, Christian Schweitzer

International Congress on Environmental Modelling and Software

Environmental changes can be related to naturally occurring phenomena or human activities such as land use. Considering that more than three quarters of the global land surface have been and are currently altered by humans, societies and their biophysical environments as coupled socio-environmental systems (SES) are more prominent than natural ecosystems. In many instances, people are directly or indirectly affected by environmental changes, and changes in environmental properties and dynamics (soil quality, water levels, forest growth, rainfall …) vice versa often change human decisions and behaviour. Due to these bidirectional influences, we emphasise the need for ( more) accurate representations …


Impact Of Species Parameter Uncertainty In Simulations Of Tree Species Migration With A Spatially Linked Dynamic Model, Julia E M S Nabel, Natalie Zurbriggen, Heike Lischke Jul 2012

Impact Of Species Parameter Uncertainty In Simulations Of Tree Species Migration With A Spatially Linked Dynamic Model, Julia E M S Nabel, Natalie Zurbriggen, Heike Lischke

International Congress on Environmental Modelling and Software

The simulation of tree species migration suffers from many sources of uncertainty.In our study we examined the influence of species parameter uncertainty on simulatedtree species migration, using the spatially linked dynamic forest landscape modelTreeMig. The impact of uncertainty becomes especially apparent under critical conditionsarising from the interaction of species sensitivities to climate, species competitionand spatial fragmentation. Therefore we examined the differences in migration successand speed in a realistic scenario including these critical conditions. The south-north migrationof the submediterranean tree species Ostrya carpinifolia through the highly fragmentedand climatically heterogeneous landscape of the Swiss Alps was simulated for27 different species parameter sets …

Ict, Integral Models And New Methods Support Farmer´S And Forester´S Integration Into Environmental Caretaking And Risk-Management, H Mayer Di Walte

International Congress on Environmental Modelling and Software

Farmers and foresters – in total worldwide more than 2 billion people - manage large parts of most of the countries, in some 90% or more. Rich, risk-exposure countries with beautiful nature like Austria or Switzerland due to mountains did a lot of excellent environmental caretaking because of intensive tourism and reduced with the help of government existing risks, supported by legislation, avalanche-, torrent- or river- departments, land consolidation units, Chambers of Agriculture, Ministerial departments etc. and were supported by farmers with a general concept: Managing a farm or forest correctly, manages also the environment well. EC´s GAP (Good Agricultural …

There are two problems slowing widespread adoption of spatially enabled hydrologic analysis, accessibility of data, and ease of use. This paper will describe and illustrate a system for sharing hydrologic analyses (geoprocessing) services and workflows that empowers GIS professionals, scientists, and citizens by making water data and its analysis accessible to a wide audience. The system leverages recent evolutions and standards in the information technology and GIS industries, particularly web services accessed through simple geospatial browser applications, cloud computing, and the increasing amount of elevation and hydrologic observations data. The GIS foundation of the system includes a high cartographic quality …


Ecosystem Climate Change Vulnerability Assessment Framework, Romain Lardy, Raphaël Martin, Bruno Bachelet, David R. C. Hill, Gianni Bellocchi Jul 2012

Ecosystem Climate Change Vulnerability Assessment Framework, Romain Lardy, Raphaël Martin, Bruno Bachelet, David R. C. Hill, Gianni Bellocchi

International Congress on Environmental Modelling and Software

Vulnerability is the degree to which human and environmental systems are likely to experience harm due to a perturbation or a stress. In the last years, it has become a central focus of the global change (including climate change). The climate change literature contains many explanations of vulnerability, stemming from the notion of sensitivity to more complex ideas, yet taking into account the exposure history of the system up to residual impacts of climate change after adaptation. This work addresses the issue of ecosystems vulnerability assessment by presenting a conceptual framework, as an attempt to generalize previous approaches. We present …

Modelling Ecosystem Services Using Bayesian Belief Networks: Burggravenstroom Case Study, Dries Landuyt, Elina Bennetsen, Rob D. Hondt, Guy Engelen, Steven Broekx, Peter L. M. Goethals

International Congress on Environmental Modelling and Software

While being studied by scientists for decades, the term ecosystem services was only recently introduced to the general public. This introduction intended broad-scale recognition of ecosystems and their value for human well-being. Both quantitative and qualitative research on ecosystem services became emerging topics in scientific research. Ecosystem service prediction models were developed varying from basic qualitative models to complex mechanistic models which enable quantification of ecosystem services. The introduction of Bayesian belief networks in ecosystem service modelling has led to an intermediate approach between both methods. Major advantages of this Bayesian network modelling approach are the model transparency which enables …


An Integrated Modeling And Data Management Strategy For Cellulosic Biomass Production Decisions, Joshua Koch, David Muth, Kenneth Mark Bryden Jul 2012

An Integrated Modeling And Data Management Strategy For Cellulosic Biomass Production Decisions, Joshua Koch, David Muth, Kenneth Mark Bryden

International Congress on Environmental Modelling and Software

Emerging cellulosic bioenergy markets can provide land managers with additional options for crop production decisions. For example, integrating dedicated bioenergy crops such as perennial grasses and short rotation woody species within the agricultural landscape can have positive impacts on several environmental processes including increased soil organic matter in degraded soils, reduced sediment and nutrient loading in watersheds, and lower green house gas fluxes. Implementing this type of diverse bioenergy production system to maximize the potential environmental benefits requires a detailed understanding of the many interwoven aspects of environmental landscapes. This paper presents a dynamic framework-based integrated modeling and data management …


Developing A Conceptual Model For The Assessment Of Personal Exposure To Air Pollution, S. Steinle, S. Reis, C. E. Sabel Jul 2012

Developing A Conceptual Model For The Assessment Of Personal Exposure To Air Pollution, S. Steinle, S. Reis, C. E. Sabel

International Congress on Environmental Modelling and Software

Human exposure to environmental pathogens and specifically air pollutants is a highlytopical issue. Clean air to breathe is a basic requirement of life and the quality of air both outdoorsand indoors is a crucial determinant of health (WHO, 2010). Air is however affected by pollutants suchas Nitrogen Oxides (NOx), Particulate Matter (PM), ground level Ozone (O3) and Carbon Monoxide(CO) which can have adverse effects on public health.Air pollutants are ubiquitous and their concentrations are typically subject to a high spatial andtemporal variability. For risk and impact assessments and for the design of effective air pollutioncontrol policies as well as public …

Lost In Translation - Mediating Between Distributed Environmental Resources., Patrick Maue, Marcell Roth

International Congress on Environmental Modelling and Software

Implementing distributed environmental modelling infrastructures supporting domain experts to discover, compose, share, and execute environmental models is subject of the ENVISION (Environmental Services Infrastructure With Ontologies) project. In this paper we focus on one specific aspect of distributed environmental models: how can we open up these infrastructures to include the wide range of data formats in the environmental modelling domain into the Web service compositions? We present the annotation pattern as solution to provide extensible resource descriptions based on flexible ontology languages. Model References link between different representations of resource descriptions, while Domain References link to terms in the common …


Operationalizing Expert Knowledge And Stakeholder Preferences In Integrated Natural Hazard Risk Assessment, Sebastian Scheuer, Dagmar Haase Jul 2012

Operationalizing Expert Knowledge And Stakeholder Preferences In Integrated Natural Hazard Risk Assessment, Sebastian Scheuer, Dagmar Haase

International Congress on Environmental Modelling and Software

Integrated natural hazard risk assessment aims at capturing the impacts and diverse consequences of natural hazards on different types of elements at risk (i.e. evaluation criteria). Typically, a risk assessor selects such evaluation criteria relying on expert knowledge. Moreover, legal frameworks, best-practice guidelines as well as manifold requirements by stakeholders should be considered in the assessment process. This is also true for risk mapping. In order to provide useful deliverables for stakeholders, their preferences in regard to content and visualization have to be borne in mind. Developing tools to assist risk assessment may focus on some or all of these …


Simulating Shocks With The Hypercycles Model Of Economic Production, Christopher Watts, Claudia R. Binder Jul 2012

Simulating Shocks With The Hypercycles Model Of Economic Production, Christopher Watts, Claudia R. Binder

International Congress on Environmental Modelling and Software

Padgett’s hypercycles model of economic production (Padgett et al. 2003) is an agent-based simulation that demonstrates the emergence of novel forms of social organisation among limited-intelligence agents. In this paper we argue that it can be extended to explore issues of resilience and the responses to shocks in complex systems of agent-environment interactions. Based on learning by doing, a simple search heuristic enables a population of firms to adapt and find system states containing a collectively self-sustaining subset of firms with production rules and mix of materials in the environment. The self-sustaining systems Padgett finds persist in spite of variability …


The Merger Clause: A Potential Defense To The Mann Frankfort Implied Promise?, Jay J. Madrid, David F. Johnson, Joseph P. Regan Jul 2012

The Merger Clause: A Potential Defense To The Mann Frankfort Implied Promise?, Jay J. Madrid, David F. Johnson, Joseph P. Regan

Texas Wesleyan Law Review

It is not difficult to imagine a case where a long time salesperson leaves her former employer and begins work with a new employer. When the salesperson began employment with her former employer, the former employer required the salesperson to sign an employment agreement. This agreement contained a covenant not to compete that stated that the salesperson would not compete with the former employer after he resigned. It also provided that she would not use the former employer's confidential information. But the agreement did not provide any express promise that the former employer would ever give the salesperson any confidential …

Slow Tourism At The Caribbean's Geographical Margins, Benjamin F. Timms, Dennis Conway Jul 2012

Slow Tourism At The Caribbean's Geographical Margins, Benjamin F. Timms, Dennis Conway

Social Sciences

The Caribbean tourism industry owes much of its success to beneficial geographical site and situation factors. Yet these geographical advantages have also contributed to the mass tourism-related pressures of economic dependency, social division and environmental degradation. We argue geographically marginal locales in the Caribbean have the potential to develop alternative tourism models that ameliorate these negative repercussions. With its conceptual roots originating from the slow food movement and theoretically rooted in Herman Daly’s ‘soft growth’ development, we propose slow tourism as a viable soft growth model that is a more culturally sensitive and sustainable genre of alternative tourism. This new …

Formalization And Community Forestry In Jambi, Indonesia: Indigenous Rights, Rural Migrants, And The Informal Divide, Matthew J. Bock Jul 2012

Formalization And Community Forestry In Jambi, Indonesia: Indigenous Rights, Rural Migrants, And The Informal Divide, Matthew J. Bock

Josef Korbel Journal of Advanced International Studies

Recent literature lauding indigenous ‘localism’ has led to the proliferation of local resource management institutions which has subsequent implications regarding the developmentconservation nexus: this localist paradigm risks entrenching a rigid definition of ‘local’, especially within the rural sector. Mobility is a fundamental tenet of a liberal democratic society while migration occurs for myriad reasons; migrant communities often remain marginalized and susceptible to human rights abuses. Similar to mass property titling programs instigated by Hernando de Soto’s policy prescriptions, state-driven, community resource management programs may also exacerbate the indigenous-migrant divide. In Jambi, Indonesia, the village forest designation (hutan desa) is a …
