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 ...


A Conceptual Model To Guide Exploration Of Global Food-Water Security, Joseph H. A. Guillaume, Matti Kummu, Miina Porkka, Olli Varis Jun 2014

A Conceptual Model To Guide Exploration Of Global Food-Water Security, Joseph H. A. Guillaume, Matti Kummu, Miina Porkka, Olli Varis

International Congress on Environmental Modelling and Software

While food security can be approached as a local issue, it is strongly influenced by factors at inter-regional and global scales related to production, transaction (e.g. trade and distribution) and consumption, and by drivers such as climate, population growth, diet change, as well as social, political and technological developments. Action on food security therefore benefits from being informed by current global patterns and potential future changes and taking an integrated approach to assessing impacts of proposed responses. Modelling can notably contribute by assessing the influence of various factors on food security. Due to the significant complexity and uncertainty involved ...


Use Of Near Real Time Earth Observation Data Infrastructures And Open Source Tools For Water Resources Monitoring And Assessment, Chris M. Mannaerts, Ben H.P. Maathuis, Petra E. Budde Jun 2014

Use Of Near Real Time Earth Observation Data Infrastructures And Open Source Tools For Water Resources Monitoring And Assessment, Chris M. Mannaerts, Ben H.P. Maathuis, Petra E. Budde

International Congress on Environmental Modelling and Software

Since several years, a rapid and ever increasing public use of geo-information data derived from earth observation satellites is noted. The use of Google and Microsoft Virtual Earth engines can be seen as generic examples of this trend. For hydrology, water resources research and professional practice, we also note a growing availability of earth observation (EO) data and products, needed for operational land and water management. Many of these data are public domain and made freely available using low-cost global data dissemination infrastructures like GEONETCast, managed by the spaces agencies EUMETSAT and NOAA amongst others, within the context of the ...
