Break-Even Year: A Concept For Understanding Intergenerational Trade-Offs In Climate Change Mitigation Policy, Patrick T. Brown, Juan Moreno-Cruz, Ken Caldeira
Break-Even Year: A Concept For Understanding Intergenerational Trade-Offs In Climate Change Mitigation Policy, Patrick T. Brown, Juan Moreno-Cruz, Ken Caldeira
Faculty Research, Scholarly, and Creative Activity
Global climate change mitigation is often framed in public discussions as a tradeoff between environmental protection and harm to the economy. However, climate-economy models have consistently calculated that the immediate implementation of greenhouse gas emissions restriction (via e.g. a global carbon price) would be in humanity’s best interest on purely economic grounds. Despite this, the implementation of global climate policy has been notoriously difficult to achieve. This evokes an apparent paradox: if the implementation of a global carbon price is not only beneficial to the environment, but is also ‘economically optimal’, why has it been so difficult to enact?One potential …
Integrated Assessment—How Does It Help Unpack Water Access By Marginalized Farmers?, Serena H. Hamilton, Wendy S. Merritt, Mahanambrota Das, M. Wakilur Rahman, Sumana S. Bhuiya, Lucy Carter, Michaela Cosijn, Christian H. Roth, Sambhu Singha, Geoffrey J. Syme

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Water is critical to the lives and livelihoods of rural communities in developing countries; however, access to water can be inequitable within communities. This paper uses a generalized integrated assessment approach to explore the determinants of water access by marginalized farmers in two villages in coastal Bangladesh, before and after the setup of local water institutions. The study was part of a broader project aimed at promoting socially inclusive agricultural intensification. An integrative framework was developed in this study to capture and link the diverse range of factors that influence the …
Blending Formative And Summative Assessment In A Capstone Subject: ‘It’S Not Your Tools, It’S How You Use Them’, Don Houston, James N. Thompson
Blending Formative And Summative Assessment In A Capstone Subject: ‘It’S Not Your Tools, It’S How You Use Them’, Don Houston, James N. Thompson
Journal of University Teaching & Learning Practice
Discussions about the relationships between formative and summative assessment have come full circle after decades of debate. For some time formative assessment with its emphasis on feedback to students was promoted as better practice than traditional summative assessment. Summative assessment practices were broadly criticised as distanced from the learning process. More recently discussions have refocused on the potential complementary characteristics of formative and summative purposes of assessment. However studies on practical designs to link formative and summative assessment in constructive ways are rare. In paramedic education, like many other professional disciplines, strong traditions of summative assessment - assessment ‘of’ learning …
Genetic Algorithm Optimization Of Sos Meta-Architecture Attributes For Fuzzy Rule Based Assessments, Andrew Renault, Cihan H. Dagli
Genetic Algorithm Optimization Of Sos Meta-Architecture Attributes For Fuzzy Rule Based Assessments, Andrew Renault, Cihan H. Dagli
Engineering Management and Systems Engineering Faculty Research & Creative Works
The analysis of an acknowledged systems of systems (SoS) meta-architecture requires a preliminary method for potential trade space exploration to ensure compliance to evolving capability requirements. It is important to assess the SoS meta-architecture concept to ensure that it satisfies all stakeholder needs and requirements in the early stages of development. There are numerous linguistic terms called key performance attributes (KPAs) that could be used to assess the different aspects of the architectures capabilities, however, too many KPAs could complicate the assessment. The initial population of suitable KPAs is reduced through non-derivative based optimization employed by a genetic algorithm (GA) …
Implementing The Oracle-Based Optimisation For An Integrated Assessment Model For Air Pollution: The Luxembourg Energy Air Quality Model, Laurent Drouet, L. Aleluia Reis, Ulrich Leopold, Daniel S. Zachary
Implementing The Oracle-Based Optimisation For An Integrated Assessment Model For Air Pollution: The Luxembourg Energy Air Quality Model, Laurent Drouet, L. Aleluia Reis, Ulrich Leopold, Daniel S. Zachary
International Congress on Environmental Modelling and Software
In this paper, we present the implementation of an advanced convex optimisation method in the framework of integrated assessment modelling. The integrated assessment of optimal policies requires a flexible and modular optimisation framework to exchange information between models while providing a consistent response in a reasonable time. In the Luxembourg Energy Air Quality model, the NOx and VOC emissions are computed by an energy model and the dispersion of air pollutants, including produced ozone, are simulated by an air quality model. Here we implement an oraclebased optimisation technique to couple the energy model and the air quality model in cost-effectiveness …

Climate Mitigation And The Future Of Tropical Landscapes, A Thomson, Katherine V. Calvin, L P. Chini, George C. Hurtt, James A. Edmonds, B Bond-Lamberty, Steve Frolking, Marshall A. Wise, A Janetos
Earth Sciences
Land-use change to meet 21st-century demands for food, fuel, and fiber will depend on many interactive factors, including global policies limiting anthropogenic climate change and realized improvements in agricultural productivity. Climate-change mitigation policies will alter the decision-making environment for land management, and changes in agricultural productivity will influence cultivated land expansion. We explore to what extent future increases in agricultural productivity might offset conversion of tropical forest lands to crop lands under a climate mitigation policy and a contrasting no-policy scenario in a global integrated assessment model. The Global Change Assessment Model is applied here to simulate a mitigation policy …

International Congress on Environmental Modelling and Software
International environmental regimes are considered key factors in dealing with global environmental problems. It is important to understand if and how these regimes are effective in solving or improving global environmental problems. In this paper we present a multidisciplinary approach to formalize knowledge on the effectiveness of environmental regimes. We constructed a conceptual framework to enhance systematic analysis of conditions that influence regime effectiveness and implemented this into a computer model using fuzzy logic reasoning. We applied the model in a preliminary analysis of two environmental regimes, the Convention on Biological Diversity and the United Nations Framework Convention on Climate …
Dss And Maf (Multi-Agencies Framework) For Sustainable Water Management, Amgad Elmahdi, Don Mcfarlane
Dss And Maf (Multi-Agencies Framework) For Sustainable Water Management, Amgad Elmahdi, Don Mcfarlane
International Congress on Environmental Modelling and Software
Water problems throughout the world can be seen as an issue of management, not a crisis of water shortage. Equitable allocation of groundwater resources is a growing challenge due to the increasing demand for water and the competing values placed on its use. Sustainable management of water resources comes with compromises and trade-offs of the other sub-systems (environment, economic and social) and almost ignores other stakeholders’ objectives and benefits. The aim of this paper is to present and discuss the hypothesis that “through multi-agency framework with supporting tools, such as a decision support system (DSS), a comprehensive framework can promote …

Agilists And The Art Of Integrated Assessment Tool Development, Rob Knapen, P. J. F. M. Verweij, Sander Janssen
International Congress on Environmental Modelling and Software
Software engineering for Integrated Assessment needs to address the fact that systems and models developed are increasingly used in participatory settings. Applying old principles of inside-out design and development using waterfall model based processes is no longer sufficient. New software engineering insights based on interaction design and iterative, agile processes for the development help in building systems from a more outside-in perspective. Based on two case studies from large European projects on integrated assessment this switch from applying old to applying new principles will be described, and its effects discussed. Elements were taken from interaction design: personas, story boards, mock-ups, …
The Use Of Ontologies In Peer Reviews Of Integrated Assessment Models, M. De Vos, N. Koenderink, B. Van Ruijven, J. Top
The Use Of Ontologies In Peer Reviews Of Integrated Assessment Models, M. De Vos, N. Koenderink, B. Van Ruijven, J. Top
International Congress on Environmental Modelling and Software
Integrated assessment models are used to analyze global change issues and they allow a better understanding of our complex environment. It is crucial to be able to relate these models to their scientific basis, both for interpretation and validation purposes. Current model evaluation procedures focus on model behavior analysis; the conceptual knowledge and assumptions embedded in integrated assessment models are hardly tested. As such, current model evaluation procedures do not contribute to the understanding of the structure of the models and the selected mechanisms and assumptions. We submit that evaluation of the scientific basis of integrated assessment models should follow …
Farm Decisions Under Dynamic Meteorology And The Curse Of Complexity, Thorsten Arnold
Farm Decisions Under Dynamic Meteorology And The Curse Of Complexity, Thorsten Arnold
International Congress on Environmental Modelling and Software
For agricultural production, climate change will have the greatest impact on water availability.At the same time, rural farming communities are at the heart of poverty reduction strategies. Furthermore,healthy rural societies must be maintained to contain urbanization and associated sprawl. Thus, sustainableadaptation strategies must take into account the complexity of societal responses. However, scientific toolsto assess such interactions are lacking. A promising approach is the integration of data and models acrossscientific disciplines and in collaboration with local stakeholders. Empirical, process-oriented models caneven quantify these interactions and feedback. As a contribution to this challenge, the project ‘Integratinggovernance and modeling’ combined the agricultural …
Integrated Modelling For Health And Environmental Impact Assessment Of Air Pollution And Climate Change, Stefan Reis, T. Oxley, Ed Rowe
Integrated Modelling For Health And Environmental Impact Assessment Of Air Pollution And Climate Change, Stefan Reis, T. Oxley, Ed Rowe
International Congress on Environmental Modelling and Software
Modelling the impacts of air pollution and climate change on human health and ecosystems in integrated assessment models (IAMs) has emerged as a key tool to inform policy decision making, where simplistic solutions are unlikely to deliver efficient and sustainable pathways for future development. Model integration is facing a complex set of challenges in different dimensions, as integrated models have to be: - Spatially explicit and of sufficiently high spatial resolution for their respective domain, with nesting approaches providing the integration across different spatial scales. - Temporally dynamic to model system responses and recovery e.g. pollutant accumulation, time-lag (e.g. of …

Ecological risk assessments typically are organized using the processes of planning (a discussion among managers, stakeholders, and analysts to clarify ecosystem management goals and assessment scope) and problem formulation (evaluation of existing information to generate hypotheses about adverse ecological effects, select assessment endpoints, and develop an analysis plan). These processes require modification to be applicable for integrated assessments that evaluate ecosystem management alternatives in terms of their ecological, economic, and social consequences.We present 8 questions that define the steps of a new process we term integrated problem formulation (IPF), and we illustrate the use of IPF through a retrospective case …
Regional Response To A Statewide Renewable Energy Standard: Status And Trends Of Wind Energy Development In West Michigan, Erik Edward Nordman
Regional Response To A Statewide Renewable Energy Standard: Status And Trends Of Wind Energy Development In West Michigan, Erik Edward Nordman
Erik Edward Nordman
This project used integrated assessment to explore and analyze regional response to Michigan’s renewable portfolio standard (RPS). The RPS required electric providers to generate ten-percent of their electricity from renewable sources by 2015. Wind was identified as a primary source of renewable energy, and much of the state’s wind resources are concentrated in the West Michigan coastal zone. About 28 percent of the state’s planned wind generation capacity is located in the four-county study area. Local governments vary in their current regulations for siting utility-scale wind farms, as well as in their attitudes toward them. The region has significant offshore …

Addressing Stakeholder Concerns Using The Integrative River Rehabilitation Model (Irrm), M. E. Borsuk, S. Schweizer, Peter Reichert
International Congress on Environmental Modelling and Software
We have previously reported on a variety of modelling methods and decision support concepts that can assist with various aspects of river rehabilitation planning and management. Here, we bring all of these tools together into an Integrative River Rehabilitation Model (IRRM) that links management actions, through morphological and hydraulic changes, to the final ecological and economic consequences. The IRRM is formulated as a probability network and represents the relevant cause-effect relations among important biotic and abiotic factors, leading to attributes (model endpoints) of concern to river system stakeholders. Together with a model of the stakeholders’ preference structure for different levels …

International Congress on Environmental Modelling and Software
The future of natural resources depends on the actions of people. Thus, whenever assessing options for a sustainable management of natural resources, it may not good enough to provide decision makers with a decision support system that integrates the technical and natural system components only. To include the human system component, it is state-ofthe- art to — in addition to demographic modeling and economic optimization — consider human actions in storylines of qualitative scenarios, which are then translated ad-hoc into quantitative scenarios of input variables of models of the technical and natural systems components. We propose modeling of societal actors …

Linking Catchment Environmental Planning To On-Ground Investment: The Scarpa Dss, N. F. Herron, T. W. Barrett, S. M. Cuddy
International Congress on Environmental Modelling and Software
The Site and Catchment Resource Planning and Assessment (SCaRPA) decision support system (DSS) has been developed for use by Catchment Management Authorities (CMA) in New South Wales, Australia to assist with catchment planning and environmental investment decision-making. The catchment planning module can be used to set targets for environmental outcomes and broad priorities for investment, using multi-criteria assessment and prioritisation tools, scenario building functions and environmental assessment models. Outputs from catchment planning can then be used to set the criteria for environmental incentives funding programs in the site-scale module, and the targeting of investment to key areas. Site-scale models are …

Ten Iterative Steps In Development And Evaluation Of Environmental Models, A. J. Jakeman, R. A. Letcher, J. P. Norton
International Congress on Environmental Modelling and Software
Models are increasingly being relied upon to inform and support natural resource management. They are incorporating an ever broader range of disciplines and now often confront people without strong quantitative or model-building backgrounds. These trends imply a need for wider awareness of what constitutes good model-development practice, including reporting of models to users and sceptical review of models by users. To this end the paper outlines ten basic steps of good, disciplined model practice. The aim is to develop purposeful, credible models from data and prior knowledge, in consort with end-users, with every stage open to critical review and revision. …
Regionalization Of Ihacres Model Parameters For In-Tegrated Assessment Across The Lake Erie, Northern Ohio Usa Basin, Richard M. Anderson, Jonathan L. Goodall
Regionalization Of Ihacres Model Parameters For In-Tegrated Assessment Across The Lake Erie, Northern Ohio Usa Basin, Richard M. Anderson, Jonathan L. Goodall
International Congress on Environmental Modelling and Software
The IHACRES model is being applied in a regionalization approach to develop streamflow predic-tions within the region of Northern Ohio, U.S.A. that drains into Lake Erie, located on the border between the U.S. and Canada. The approach to-date is based on independent univariate regressions of model parameters on watershed attributes for a collection of 11 watersheds. Anderson et al. (2005) used one of these regression relationships to represent possible effects of declining forest cover on streamflow, but did not obtain regional models for the parameters of the routing model of IHACRES. Here we apply and “validate” a regionaliza-tion approach to …

Agricultural systems continuously evolve and are forced to change as a result of a range of global and local driving forces. Agricultural and environmental policies are increasingly designed to contribute to the sustainability of agricultural systems and to enhance contributions of agricultural systems to sustainable development at large. The effectiveness and efficiency of such polices in realizing desired contributions could be greatly enhanced if it were possible to perform ex-ante assessments. The European Commission has recently introduced impact assessment of its policies as an essential step in policy development. This paper presents the design and first prototype of a computerized …

International Congress on Environmental Modelling and Software
Key clients for regional or national assessment capabilities are government and industry policymakers, who must deal with constantly changing policy questions. For instance, adaptation to climate change has relatively recently come onto the policy agenda, as has the interaction between adaptation and greenhouse gas mitigation. ’Integrated assessment’ has therefore become a common approach that attempts to demonstrate the policy relevance of science. It is intended to inform policies that ultimately lead to better risk management of agro-ecosystems (amongst other objectives). Increasingly policy stakeholders also demand realistic assessments of uncertainties that are associated with the scenarios underpinning such integrated assessments. This …
