International Geosphere-Biosphere Programme

Project Description
The International Geosphere-Biosphere Programme (IGBP,
is an interdisciplinary scientific activity established and sponsored by the
International Council of Scientific Unions (ICSU). The Programme was instituted
by ICSU in 1986, and the IGBP Secretariat was established at the Royal Swedish
Academy of Sciences in 1987.

The IGBP programme is focused on acquiring basic scientific knowledge about the
interactive processes of biology and chemistry of the Earth as they relate to
global change. The goal of the programme is to describe and understand the
interactive physical, chemical and biological processes that regulate the total
Earth system, the unique environment that it provides for life, the changes
that are occurring in this system, and the manner in which they are influenced
by human actions.

IGBP is composed of eleven program elements. These are composed of eight
broadly discipline-oriented projects, called Core Projects, covering such
topics as atmospheric science, terrestrial ecology, oceanography, hydrology,
and links between the natural and the social sciences. Three Framework
Activities on data, modelling, and regional research, facilitate incorporating
scientific results into a holistic picture. The detailed planning and
implementation of each Core Project is directed by a Scientific Steering
Committee, and the Framework Activities are each guided by a Scientific
Steering Committee or a Task Force.

Current and Past Core Projects:
Analysis, Integration and Modeling of the Earth System (AIMES)
Biospheric Aspects of the Hydrologic Cycle (BAHC)
Global Analysis, Interpretation and Modelling (GAIM)
Global Change and Terrestrial Ecosystems (GCTE)
Global Ocean Ecosystem Dynamics (GLOBEC)
Global Lang Project (GLP)
International Global Atmospheric Chemistry Project (IGAC)
Integrated Marine Biogeochemistry and Ecosystem Research (IMBER)
Integrated Land Ecosystem-Atmosphere Processes Study (iLEAPS)
Joint Global Ocean Flux Study (JGOFS)
Land-Ocean Interactions in the Coastal Zone (LOICZ)
Land-Use and Land-Cover Change (LUCC)
Past Global Change (PAGES)
Surface Ocean-Lower Atmosphere Study (SOLAS)
Global Change System for Analysis, Research and Training (START)
