  • A personal note on IGBP and the social sciences


    Humans are an integral component of the Earth system as conceptualised by IGBP. João Morais recalls key milestones in IGBP’s engagement with the social sciences and offers some words of advice for Future Earth.

  • IGBP and Earth observation:
    a co-evolution


    The iconic images of Earth beamed back by the earliest spacecraft helped to galvanise interest in our planet’s environment. The subsequent evolution and development of satellites for Earth observation has been intricately linked with that of IGBP and other global-change research programmes, write Jack Kaye and Cat Downy .

Regionalisation of the Nitrogen Visualisation Tool

The nitrogen cycle is a complex one, and one that is being modified substantially due to human activities. This modification has a bearing on a wide range of issues such as biodiversity, human health, eutrophication of coastal environments, atmospheric greenhouse-gas concentrations and food production.

In view of the profound policy implications of the alteration of the nitrogen cycle, a nitrogen visualisation tool – aimed at providing an overview of key issues pertaining to nitrogen – was launched at the International Nitrogen Conference, organised in Brazil in 2007.

This tool offers a global perspective, but does not encompass the complexity that arises from regional or country-level variations in the behaviour of nitrogen and its compounds. Yet, such insights can be very useful as policy decisions are often taken at the national level. With this in mind, this IGBP fast-track initiative aims to extend the capabilities of the existing tool in a manner that allows regional complexities to be portrayed simply and effectively.

Coordinator

Albert Bleeker (Energy Research Centre of the Netherlands), Jim Galloway (University of Virginia, USA). Jan Willem Erisman (Energy Research Centre of the Netherlands) is the IGBP SC contact for this project.

Specific goals

1. To understand the regional variations in the behaviour of the nitrogen cycle, the specific issues involved (e.g., eutrification of coastal waters, food shortages, etc)
2. To communicate the regional variations via modifications to the nitrogen visualisation tool

Products envisaged

1. Regionalized version of the nitrogen visualisation tool

Meetings

Workshop in early 2010
