Fernández-Prieto D., Sabia R. Remote Sensing Advances for Earth System Science: The ESA Changing Earth Science Network: Projects 2009-2011

Springer, 2013. — 101 p.To better understand the various processes and interactions that govern the Earth system and to determine whether recent human-induced changes could ultimately de-stabilise its dynamics, both natural system variability and the consequences of human activities have to be observed and quantified. In this context, the European Space Agency (ESA) published in 2006 the document ‘‘The Changing Earth: New Scientific Challenges for ESA’s Living Planet Programme’’ as the main driver of ESA’s new Earth Observation (EO) science strategy. The document outlines 25 major scientific challenges covering all the different aspects of the Earth system, where EO technology and ESA missions may provide a key contribution. In this framework, and aiming at enhancing the ESA scientific support towards the achievement of ‘‘The Challenges’’, the Agency has launched the ‘‘Changing Earth Science Network’’, an important programmatic component of the new Support To Science Element (STSE) of the Earth Observation Envelope Programme (EOEP). In this foreword, the objectives of this initiative are summarized and the list of the projects selected in the first call, and recently completed, is provided. An in-depth overview of such projects will be provided in the following book chapters.
