Achieving a sustainable development trajectory in Amazonia is one of the key challenges facing Brazil, and is also an important international concern. ODYSSEA assembles an internationally renowned European and Brazilian multidisciplinary and intersectoral team. We aim to produce fundamental science and tools in order to build an innovative multi-and interdisciplinary observatory to monitor and assess dynamic interactions between Amazon societies and their environments. This observatory will serve as a basis for policy development that integrates social, environmental, political-economic and human health dimensions. Our methodology puts the society at the heart of the observatory’s building process, engaging stakeholders and decision makers in the research to favour advancement of their objectives and commitment to sustainable development issues. Building on knowledge framed around ongoing bilateral projects, ODYSSEA brings together several independent networks of international and Brazilian researchers which all have long-term experiences in the Amazon of environmental and social research, each with their own expert skill-sets. We expect significant advances in our understanding of the different feedbacks and linkages between the panoply of pressures exerted on the environment, the factors determining the vulnerability of local populations to environmental shocks and in the evaluation of governance and institutional arrangements aiming at promoting adaptation. We aim to enhance the capacity of Brazilian institutions to assess and reduce the vulnerability of populations in Amazonia. ODYSSEA will help unify an increasing number of bilateral arrangements for research and innovation between individual European countries and Brazil. Whilst these connections are proving fruitful in their own right there is a largely untapped opportunity to upscale the intensity and diversity of connections between Europe and Brazil on all levels of education, research and development.

Earth and environmental sciences require a large panel and volume of data from satellite, in-situ observations, models, omics experiments... Earth system domains are interconnected and even if interfaces between domains appear of primary importance for several studies with large societal impacts, such as climate change, agriculture and food, human safety and health, the present digital architecture is based essentially on distributed and domain-dependent data repositories inducing real difficulties for integrated uses of all the environmental data. To go beyond this state-of-the-art, the overall objective of FAIR-EASE is to customize and operate distributed and integrated services for observation and modelling of the Earth system, environment and biodiversity by improving the TRL of their different components implemented in close cooperation with user-communities, the European Open Science Cloud and research infrastructures in their design and sustainable availability. The project will: (1) Improve a FAIR-EASE data discovery and data access service, relying on pre-operational existing services, in order to provide users with an easy and FAIR tool for discovery and access to environmental multidisciplinary and aggregated data-sets as managed and provided by a range of European data infrastructures; (2) Set up a FAIR-EASE Earth Analytical Lab, with EOSC connectivity supporting, through web-based interfaces, predefined processing tools and on-demand data visualization services for remote analysis and processing of heterogeneous data facilitating the cross-disciplinary collaboration, reducing the time to results and increasing productivity; and (3) Develop a number of multidisciplinary Use Cases (UCs) to contribute requirements for the FAIR-EASE system components and to validate and demonstrate the capabilities of the FAIR-EASE service for supporting open science.
