• From clouds to carbon:
    land-atmosphere interactions
    in the spotlight


    Understanding the interface between the land and the atmosphere has been an important component of IGBP’s research. Here we highlight three recent contributions that resulted from research sponsored by the Integrated Land Ecosystem–Atmosphere Processes Study (iLEAPS).

  • Coastal megacities:
    risks and opportunities


    Every year, more and more people are flocking to live near the sea’s edge, often congregating in massive cities. Sophie Blackburn and Mark Pelling explore what happens when urban and coastal zones collide.

Background

Global-change research requires long-term coordinated efforts from an international research community.
IGBP networks:
  • share expertise on experimental technologies
  • help transfer this expertise to developing countries
  • interact with modeling communities to ensure the latest understanding is used
  • conduct periodic syntheses on focused topics.

This approach leads to faster scientific progress and more comprehensive understanding of global processes and their regional variations.

An example of this approach is FLUXNET, a global network of over 240 flux towers across all major ecosystems continuously measuring key fluxes between the land and the atmosphere. Supported by IGBP's project iLEAPS and others, FLUXNET is making major contributions to the understanding of processes that control the land-atmosphere exchanges of water, energy and carbon dioxide.

FLUXNET has helped:

  • reveal the effect of changing growing season length on net carbon dioxide exchange
  • quantify variations in light-use efficiency (and hence gross primary production) with cloudiness
  • test remote sensing algorithms used in seasonal forcing of models for computing carbon exchange.

    IMBER ClimEco4 Summer School


    IMBER focuses on the interactions and linkages between biogeochemical cycles and food webs, including humans, with the aim of improving the predictive capacity for marine ecosystems increasingly affected by global change. As the marine environment is very complex, particularly in the context of global change, indicators are often used to provide a practical and economical way to track the state of ecosystems. This fourth IMBER summer school, ClimEco4, will continue IMBER’s focus on fostering research at the interface of natural and human systems. It will be structured around lectures and activities that focus on indices of climate change, climate impacts, and ecosystem services, and how these are linked to indices for socio-economic and policy information in relation to climate-ecosystem interactions.
