The project aims to develop an information system for quantifying savanna water use and biomass production on a regional scale, with the ultimate objective of supporting decision-making processes. This effort directly addresses the European H2020 priorities of sustainable rural development and food security. Savannas are among the most complex, variable and extensive agrosilvopastoral systems on Earth (~20%). One fifth of the world’s population depend upon them, although they are extremely vulnerable to changes in land use and climate. These changes affect not only ecosystem functioning, but also the land-atmosphere linkages and regional carbon cycle, in ways still unknown. Since savannas are greatly influenced by human activities, private/institutional practices play a key role in their conservation. The integration of Earth Observation data into process-based models will enable us to map the evolution of the ecosystem health, improving their management, productivity and resilience.
