[Termes IGN] risque environnementalRésumé : (Auteur) Society and politicians are demanding operational information services in order to manage our planet's environment, understand and mitigate the effects of climate change, and ensure civil security for Europe's citizens. GMES can respond to these challenges by providing accurate, up-to-date and globally available information on an operational basis to European, national, regional and local entities. Important decisions are expected in the next two years on the future of GMES, including finalisation of the funding scheme for developing the infrastructure, and progress in setting up its long-term governance and funding. ESA's responsibility is to provide the GMES satellites, which includes developing a dedicated space infrastructure and coordinating the space contributions from all the partners.

[Termes IGN] ressources en eauRésumé : (Auteur) Water resources, the “blue gold” of the 21st century, can be successfuly minitored from space using Earth-observation technology. Satellite can measure precipitation, atmospheric water content, soil moisture, surface run-off, lake and river levels, groundwater reservoirs, as well as ice and snow cover. Improved sensors, better modelling and a deeper understanding of the underlying science have substantially advanced our knowledge of the global water cycle in recent years. However, there are still major shortcomings in both the understanding and the observation of key parameters. The estimation of groundwater resources, for example, poses a major challenge, as they are not directly visible from space. Indirect methods based on gravity-field measurements, interferometery and altimetric monitoring of rivers need to be applied to gain knowledge of reservoir volumes and flows. In order to improve our capabilities and to offert this technology to people in developing countries, ESA has launched a new programme focusing on the use of space technology for water-resource management in Africa. The initiative, called 'TIGER' is a direct followup engagement of ESA's strong engagement in the 2002 Johannesburg World Summit off Sustainable Development, and implements its recommendations through concrete actions.
