Global Change
“Changes in the global environment (including alterations in the climate, land productivity, oceans or other water resources, atmospheric chemistry, and ecological systems) that may alter the capacity of the earth to sustain life.”

IAI Main Goals
• Conduct and promote research on global change and their interaction with human activities [Agreement Art.II a) to e), g), h)]
• Improve public awareness and serve as an effective interface between science and the governmental policy process [Agreement Art II, f)]

Involve a large and wide spectrum of issues
• Multifaceted
• Inter-, Intra- & trans-disciplinary (cross-cutting)
• Multi scales (time & space)
• Required interactions and dialogue between:
- Hard sciences (Earth System Science ESS) -- well established methodologies
- Soft sciences (HD, socio-economic) -- no standard methodologies

Global Environmental Change Data
Needed for
• SCIENCE
• MANAGEMENT, POLICY , DECISION MAKING
Establishment of open and on-going processes identifying data and information requirements from research scientists and managers and policy makers may be of great help

• an Internet based system dedicated to the dissemination of scientific information produced by the IAI projects, following a pre-defined standard (Z3950), as well as to ease the exchange of that information between institutions/organizations. It was developed by CIESIN (Center for International Earth Science Information Network) .
What is IAI-DIS ?
IAI-DIS main objectives
• Disseminate global change research information produced by the IAI, and other affiliated institutions, and
• Contribute for the standardization and exchange of scientific data between different institutions.

Main features of the IAI-DIS system:
• WEB access and user-friendly interface;
• Integrated Search and Retrieval modules; and
• Two levels of METADATA ( “information about data” – a short, organized and searchable form of documentation used to find data).
What IS NOT IAI-DIS
• It is not a statistical system; and • It is not a tool to make automatic comparisons between actual data

Drawbacks
• System up and running for 4 years – some components obsolete
• Present system is not easy for a layman user
Future actions
• “Aggiornamento” - update of the system - increase the “user-friendliness”
• Creation of a distributed network of GEC DIS in the Americas
