Ten Iterative Steps In Development And Evaluation Of Environmental Models, A. J. Jakeman, R. A. Letcher, J. P. Norton
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 …
Integrated Assessment Of Agricultural And Environmental Policies – Towards A Computerized Framework For The Eu (Seamless-If), Martin Van Ittersum, Frank Ewert, Johanna Alkan Olsson, Erling Andersen, Irina Bezlepkina, Floor Brouwer, Marcello Donatelli, Guillermo Flichman, Thomas Heckelei, Lennart Olsson, Alfons Oude Lansink, Andrea-Emilio Rizzoli, Tamme Van Der Wal, Jacques Wery

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 …
Integrated Assessments Of Climate Variability And Change For Australian Agriculture – Connecting The Islands Of Knowledge, Holger Meinke, Mark Howden, Rohan Nelson
Integrated Assessments Of Climate Variability And Change For Australian Agriculture – Connecting The Islands Of Knowledge, Holger Meinke, Mark Howden, Rohan Nelson
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 …
