Sociocultural Adaptation of Caboclos Communities to Extreme Tidal Events in the Amazon Estuary of Brazil

Over the past 30 years, the Caboclos peoples of the Amazon region have noticed changes in the tidal floods, known locally as lançantes, on the floodplains of the Amazon Estuary, Brazil. These changes have had an adverse effect on traditional crop production, as well as some positive effects on traditional agroforestry, forest management and fishery. They are adapting by shifting from cropping to agroforestry and forest management - both long-term land use systems - and fisheries, and by maintaining both rural and urban households, to mitigate the cost of extreme events.
This project aims to increase the resilience of the systems developed by Caboclos communities, and to scale-up the findings to the municipal and state government level across the region, which is home to some 5 million people. The research team will carry out socioeconomic assessments, hydro-climatic measurements land and resource use surveys and fish stock inventories. They will train students, rural extension agents and selected farmers to collect social and environmental data, monitor sociocultural responses, and manage early warning systems.
Project outputs will include early warning systems for extreme tidal events, information systems for decision-making, adaptation plans for district municipalities, policy briefs, toolkits for communities and local leaders, and publications in peer-reviewed journals and popular magazines.
