Reconciling Information From Climate-Economic Model Ensembles, A. Shchiptsova, D. Kovalevsky, E. Rovenskaya Jul 2016

Reconciling Information From Climate-Economic Model Ensembles, A. Shchiptsova, D. Kovalevsky, E. Rovenskaya

International Congress on Environmental Modelling and Software

To date, no model building process can guarantee full representation of the complex climate-economic processes and narrow down the uncertainty associated with future climate projections. Multiple highly detailed models are developed by individual research groups to capture various known aspects of the climate processes. Normally, these models represent only a part of the climate-society system due to its complexity. On the other hand, a number of the simplified integrated assessment models (IAMs) have been put forward in the attempt to introduce the full causal loop between accumulated emissions, economy and climate, and study associated uncertainty. We present a simplified system ...

Climate Change Impacts On Precipitation Extremes, Flows And Flash Floods In Mediterranean Mesoscale Catchments, Antoine Colmet Daage, Sophie Ricci, Emilia Sanchez-Gomez, Valérie Borrell Estupina, Eric Servat, Cécile Llovel

International Congress on Environmental Modelling and Software

Mediterranean meso-scale river catchments are submitted to extremes floods events linked to intense convective precipitation and local hydrologic features (karst, soil moisture, land use).The Mediterranean region is known to be one of the most affected areas by global warming, and it is likely that changes can be expected in the hydrological cycle. The aim of this study is to assess the climate change impacts on extreme precipitation events using a so-called “futurization” method, in which a transfer function is built by comparing the quantiles of distribution for both present and future climate precipitation. A number of historical flood events ...


Informing Adaptive Strategies For The Colorado Basin, David Groves, Robert Lempert, Jordan Fischbach, Evan Bloom Jul 2016

Informing Adaptive Strategies For The Colorado Basin, David Groves, Robert Lempert, Jordan Fischbach, Evan Bloom

International Congress on Environmental Modelling and Software

The Colorado River is the single most important source of water in the southwestern United States, providing water and power for nearly 40 million people and water to irrigate more than five million acres of farmland across seven states and for 22 Native American tribes. A vast physical and institutional infrastructure exists to provide water, as well as hydropower, recreational opportunities, environmental services, and other benefits to all these users. However, increasing demand, a decade of drought, and expectations of a significantly changing future climate have put the system under significant and deeply uncertain stress. This paper employs and extends ...


Water Resource Management With The Management Software Manuela, Monika Von Haaren Jul 2016

Water Resource Management With The Management Software Manuela, Monika Von Haaren

International Congress on Environmental Modelling and Software

The impact of climate change with increasing droughts will lead to an increase of water consumption in agriculture. Even in Germany, agricultural land is already irrigated intensively to secure harvests at a higher level. The demand for additional irrigation will lead to conflicts between agriculture, water management and nature conservation. This paper shows a new way for the evaluation of water use in agricultural farming. With the developed method stakeholder can assess the water consumption for irrigation in agriculture, which is transferable, regionally applicable and comparable. The water-module is available as a new plug-in in the management software MANUELA and ...


Modelling Adaptive Behaviour In Spatial Agent-­Based Models: Coastal Cities And Climate Change, Tatiana Filatova, Erik Horstman, Suzanne J.M.H. Hulscher, Ju-­Sung Lee, Johan De Waard Jul 2016

International Congress on Environmental Modelling and Software

A major part of world population lives in coastal and delta areas threatened by adverse consequences of climate change (increasing probabilities or severity of floods and hurricanes). It might lead to a forced displacement of up to 187 million people in coastal zones. Still, exposure and vulnerability in coastal areas rapidly escalate due to the clustering of population and growth of property values in flood-­prone areas. Land markets driven by individual location preferences are crucial in the formation of spatial patterns of activities and the economic value they receive. Under the conditions of uncertainty where probabilistic disasters and rich ...


Explicit Cost Accounting For Adaptation, Mitigation And Ecosystem Service Provision In Agriculture, Franz Sinabell, Karin Heinschink, Christoph Tribl Jul 2016

Explicit Cost Accounting For Adaptation, Mitigation And Ecosystem Service Provision In Agriculture, Franz Sinabell, Karin Heinschink, Christoph Tribl

International Congress on Environmental Modelling and Software

Farmers, policy makers and scientists are well aware of this problem: obtaining sound cost information for climate change adaptation and mitigation measures in agriculture or ecosystem service provision by agriculture is burdensome. In most cases, data sets are developed for a specific region with a given set of management variants for a baseline period. Adapting such information to another region or adjusting costs to expected future price scenarios requires additional efforts and frequently done an ad-hoc and case by case. A new tool is presented that can be used to identify and analyze the entangled effects of future climate and ...


Autoflow© - A Novel Application For Water Resource Management And Climate Change Response Using Smart Technology, Khoi Anh Nguyen, Oz Sahin, Rodney Anthony Stewart, Hong Zhang Jul 2016

Autoflow© - A Novel Application For Water Resource Management And Climate Change Response Using Smart Technology, Khoi Anh Nguyen, Oz Sahin, Rodney Anthony Stewart, Hong Zhang

International Congress on Environmental Modelling and Software

Urban areas are increasingly at risk from climate change, with negative impacts predicted for human health, the economy and ecosystems. These risks require responses from cities to improve their resilience. Several analysis platforms have been developed worldwide to help effectively control and response to these impacts from different angles, including water resources management, energy production and consumption management, air pollution control, or other natural resources management. To contribute to this goal, Griffith University in Australia has developed Autoflow©, a smart application for water demand analysis and carbon emission monitoring and prediction. Various advanced mathematical models have been embedded into ...

Hydrological Water Resources Assessment Of Cega-Eresma-Adaja Watershed System Using Swat Model, David A. Rivas, Angel De Miguel, Bárbara Willarts

International Congress on Environmental Modelling and Software

In the hydrological assessment of water bodies, modeling is a key fact in water management strategies of watersheds and serves as a tool for decision making considering environmental issues as the core of sustainable development in the region. In this direction, SWAT model (Soil and Water Assessment Tool) was used to assess the water availability related with agricultural management in the watersheds of the tributary rivers Cega, Eresma and Adaja of Duero’s River in Spain both in the current and future climate change scenarios. To define the HRUs, land use maps from remote-sensing processes were used, extracting the agricultural ...

International Congress on Environmental Modelling and Software

The Colorado Front Range Corridor is a mixture of urban, agricultural, grassland, and diverse forest types, making it an ideal natural laboratory to investigate feedbacks and interactions of coupled human and natural systems. We explored future scenarios of human-driven land use change and natural vegetation dynamics using the CHANGE model, which integrates a demand-allocation land use change module, a succession module for natural vegetation dynamics, and a spatially explicit fire initiation and spread module. We used the model to project landscape change over an approximately 48000 km2 study area from 2005 through 2050 under A2 and B1 emission scenarios ...
