Global Biogeochemical Cycles and Reduction of Uncertainty in Climate Models

P. Ciais ( LSCE, France)

Better knowledge of photosynthesis is of importance for food and fiber production, and for understanding the terrestrial carbon cycle. Information about the observed response of ecosystem photosynthetic activity and net primary productivity to large scale climate variability, including climatic extremes is also informative to understand strengths and weaknesses of current carbon cycle models, and help reduce their uncertainty on future projections. The presentation will present attempts to evaluate photosynthesis in models using current EO datasets, at regional and global scale, in the context of future fluorescence dedicated spaceborne observations.

10:05

Using Remote Sensing to aid assessing Agriculture and Food Security under variable climate conditions

R. Quiroz ( CGIAR, Peru)

Achieving sustainable food security in a world with growing population, changing diets and a changing climate is a major challenge. Climate related agricultural failures already cause economic losses and undermine food security, and these are likely to become more severe as global warming continues. The CGIAR research Program on Climate Change, Agriculture and Food Security (CCAFS) seeks to overcome the threats to agriculture and food security, exploring new ways of helping vulnerable rural communities adjust to global changes in climate. CCAFS integrates and applies the best and most promising approaches, tools and technologies. The presentation highlights CCAFS activities featuring different applications of remote sensing in agricultural research.

Traits-based Approaches to Understand Temporal Dynamics and to Constrain Fluorescence Modeling

P. van Bodegom (Vrije Univ., The Netherlands)

Traits-based approaches are increasingly applied to model vegetation distribution and carbon and water fluxes. Chlorophyll fluorescence may be considered a plant trait operating at the short time scales and is linked to traits affecting photosynthesis and light acclimation at medium (Chlorophyll contents) and long (leaf nitrogen, specific leaf area) time scales. Ecological concepts may aid better understanding these temporal interactions to i) improve retrieval schemes and ii), vice versa, allow incorporating fluorescence into (traits-based) global vegetation models. In this presentation, some of these concepts will be explored.

11:30
