Atlas: A Tool To Model Spatial-Temporal Dynamics Of Processes Influencing Ecosystem Services, Hugo Thierry, Aude Vialatte, Claude Monteil, Annie Ouin Jul 2016

Atlas: A Tool To Model Spatial-Temporal Dynamics Of Processes Influencing Ecosystem Services, Hugo Thierry, Aude Vialatte, Claude Monteil, Annie Ouin

International Congress on Environmental Modelling and Software

Biodiversity provides various benefits to humankind throughout what is defined as ecosystem services. Within a specific ecosystem, a wide range of ecosystem services can be identified. During the past decades, human intervention has aimed to increase some services such as food production through agricultural intensification, at the expense of other services such as water regulation. Mapping, evaluating and quantifying each of these ecosystem services provided by biodiversity to crop production could help to increase the multi-functionality of agricultural landscapes. In this context, we developed a spatially-explicit model called ATLAS (AgriculTural LandscApe Simulator). ATLA ...


Rural Livelihood, Biodiversity And Carbon Stock In Vietnam Mountains: Agent-Based Modeling To Anticipate Trade-Offs, Quang Bao Le Jul 2016

Rural Livelihood, Biodiversity And Carbon Stock In Vietnam Mountains: Agent-Based Modeling To Anticipate Trade-Offs, Quang Bao Le

International Congress on Environmental Modelling and Software

Assessment of future multiple ecosystem services driven by alternative land-use policies is useful for supporting decisions about what and where to invest for the best overall environmental and developmental outcomes. The task faces a great challenge due to the inherent complexity of human- landscape systems and trade-offs between rural livelihood improvement, biodiversity conservation and carbon sequestration. Agent-based system models have been recognized to be well suited to simulate the co-evolutions of the community and landscape systems in response to policy interventions. The study applies the Land Use Dynamics Simulator (LUDAS) framework to a mountain watershed in central Vietnam for anticipating ...


Trade-Offs Between Carbon Storage, Crop Yield Production And Water Supply At The Global Scale, Sven Lautenbach, Anita D. Bayer, Almut Arneth Jul 2016

Trade-Offs Between Carbon Storage, Crop Yield Production And Water Supply At The Global Scale, Sven Lautenbach, Anita D. Bayer, Almut Arneth

International Congress on Environmental Modelling and Software

Through land-use, humans affect natural ecosystem functioning and ecosystem services (ES). The present pattern of land-use types developed over the last millennia in response to a complex interplay of natural-system constraints and socio-economic pressures. However, the current land-use pattern might not be considered optimal in terms of its provision of a variety of ES. At the global scale food security, water availability and carbon storage are three objectives of highest importance. Knowledge about the trade-offs between these objectives is of concern if global pathways for future developments are discussed. To provide information on these trade-offs we evaluate the global configuration ...


Integrating Human Agency And Ecosystem Services: An Abm Perspective On Food, Stefano Balbi, Ferdinando Villa Jul 2016

Integrating Human Agency And Ecosystem Services: An Abm Perspective On Food, Stefano Balbi, Ferdinando Villa

International Congress on Environmental Modelling and Software

Food is a primary provisioning ecosystem service. The concept of ecosystem services only focuses on the flow of services from nature to humans and doesn’t consider human flows, which include both the flows from human to nature (i.e. the co-production of ecosystem services or environmental pressures caused by humans) and human to human flows (i.e. social flows). Neglecting human flows is a main issue for modelling food provision within the ecosystem services framework, especially so under a food security perspective, where food access greatly depend on economic entitlements and social networks. We use the example of food ...


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 ...


Dynamic Feedback Between Land Use And Hydrology For Ecosystem Services Assessment, Seleshi Getahun Yalew, Tobias Pilz, Christian Schweitzer, Stefan Liersch, Johannes Van Der Kwast, Marloes L. Mul, Ann Van Griensven, Pieter Van Der Zaag Jun 2014

Dynamic Feedback Between Land Use And Hydrology For Ecosystem Services Assessment, Seleshi Getahun Yalew, Tobias Pilz, Christian Schweitzer, Stefan Liersch, Johannes Van Der Kwast, Marloes L. Mul, Ann Van Griensven, Pieter Van Der Zaag

International Congress on Environmental Modelling and Software

Ecosystem services assessment requires an integrated approach, as it is influenced by elements such as climate, hydrology and socio-economics, which in turn influence each other. However, there are few studies that integrate these elements in order to assess ecosystem services. Absence of integrated approach to modelling hydrological and land-use changes, for instance, often oversights the dynamic feedback between the two processes. Dynamic changes in land-use should be fed into hydrological models and vice-versa at each time-step for a more realistic representation. In this study, this approach is demonstrated with a case study of the uThukela catchment, South Africa. There is ...
