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 security to provide …

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, model …

Daugherty Water for Food Global Institute: Faculty Publications

In 1950 the global population was just over 2.5 billion. Now, in 2013, it is around 7 billion. Although population growth is slowing, the world is projected to have around 9.6 billion inhabitants by 2050. Most of the population increase will be in developing countries where food is often scarce, and land and water are under pressure. To feed the global population in 2050 the world will have to produce more food without significantly expanding the area of cultivated land and, because of competition between a greater number of water users, with less freshwater. On top of land and water …
