The Amazon region has been facing rapid changes, due to deforestation, climate change, demography, leading to environmental disruption and increasing populations vulnerability. To understand these changes and enable local populations to maintain and consolidate their livelihoods, we mobilized a network of more than 100 researchers, European and Brazilian, to build an Observatory of Socio-environmental Dynamics, together with the INCT ODISSEIA, financed by Brazil. 5 sites were selected, to analyse a diversity of situations across the Amazon: the Northeast of Pará, Santarem, Manaus, the BR 163 and the border with French Guiana.
To be relevant for society, our observatory follows citizen science principles, combining data production with a strong social mobilization. We developed in particular a pilot observatory in the region of Santarém. We empowered young community leaders and they collected information from 544 families in 62 communities. Based on this data, we are discussing with the community representatives what strategies they can implement to help populations adapt to changes.
Mainly based on remote sensing, scientists collected data in the 5 sites and developed monitoring tools to assess floodplain hydrology and aquatic biodiversity, forest type and structure and evaluate the efficiency of protected areas, assessed the links between land cover and local rainfall regimes and followed intensification of agriculture and water resource use. In particular, ODYSSEA collaboration supported a pan-tropical assessment of biodiversity and the future of hyperdiverse tropical ecosystems, published in Nature (Barlow et al. 2018), covered by multiple news agencies.
ODYSSEA also contributes to the dissemination of knowledge by participating in the construction of a platform that will enable to analyse the implementation of Sustainable Development Objectives at the municipal level in Amazonia. Our first policy analyses show strong interdependency between policy instruments, often leading to contrary effects. To answer citizen demands, it is necessary to reconsider how to bring actions and policies to work together and not one against another.
