Humankind is facing unprecedented global environmental and social challenges in terms of food,water and energy security,resilience to natural hazards,*** address these challenges,international organizations have defined a list of policy actions to be achieved in a relatively short and medium-term *** development and use of knowledge platforms is key in helping the decision-making process to take significant decisions(providing the best available knowledge)and avoid potentially negative impacts on society and the *** knowledge platforms must build on the recent and next coming digital technologies that have transformed society–including the science and engineering *** Earth Data(BED)science aims to provide the methodologies and instruments to generate knowledge from numerous,complex,and diverse data *** science requires the development of Geoscience Digital Ecosystems(GEDs),which bank on the combined use of fundamental technology units(*** data,learning-driven artificial intelligence,and network-based computing platform)to enable the development of more detailed knowledge to observe and test planet Earth as a *** manuscript contributes to the BED science research domain,by presenting the Virtual Earth Cloud:a multi-cloud framework to support GDE implementation and generate knowledge on environmental and social sustainability.
