Paranaguá Bay, by Rodrigo Postol

This initiative aims to foster regional bioeconomies in Southern Brazil based on adaptation measures for mangrove restoration and coastal resilience, together with the creation of new jobs in regional contexts strongly affected by climate change. It considers the development of a “collaborative laboratory" with local institutions to promote the use of advanced digital systems integrated with in-situ techniques for the analysis, quantification and valorisation of the variation in mangrove carbon stocks[1], as well their loss and recovery due to natural and(or) land-use changes. The ultimate goal is to foster Mangrove Ecosystem Management through the sustainable and natural growth/exploration of blue carbon in natural mangroves.

The project is focused in two of the most important subtropical estuarine environments in Southern Brazil, respectively Bay of Paranaguá, in the state of Paraná, and Babitonga Bay in Santa Catarina.

The rational of the project derives from the fact that Brazil has the third mangrove extension in the world[2], and mangrove forests are one of the most productive and efficient long-term natural carbon sinks and as such have been identified alongside seagrasses and saltmarshes as key ‘blue carbon’ ecosystems[3]. Typically, they store up to 15 times more carbon per hectare than terrestrial soils and sequester carbon 10–50 times faster than terrestrial forests[4].

The regional context is affected by high level of social and economic vulnerability, which can only be tackled through new forms of ecosystem management and social intervention through the economic valorisation of carbon stocks in the mangroves (i.e., “blue carbon). The project will introduce and leverage the use of new methodologies, making use of an “user-driven”, people-centred approach, for mangrove ecosystems exploration in Brazil[5].

This project will leverage ongoing activities developed in the South of Brazil by +Atlantic, governmental institutions (Chico Mendes Institute – ICMBIO; Brazil National Council for Scientific and Technological Development – CNPQ), industry and NGO’s (APPIX – Innovation and Technology, or Pró-Babitonga Group – GPB, respectively), together with local universities (Federal University of Santa Catarina, UFSC; University of the Vale de Itajaí, UNIVALI). They have considered, over the last few years: i) the development of web-tool Coastal Analyst System from Space Imagery Engine (CASSIE[6]); ii) the development of several projects focused on coastal risks, coastal communities and sea level rise;, and iii) adaptation measures using nature based solutions (mangrove restoration) to improve coastal resilience (e.g., Baysqueeze project[7], RiskPorts project[8]).

The project will contribute to several ongoing activities at local, regional, and national scale, including:

  • Local Economy: foster regional bioeconomies in Southern Brazil based on adaptation measures for mangrove restoration and coastal resilience; Foster, develop and implement blue carbon market at local, regional, and national scale.
  • Innovation: promote the use of advanced digital systems integrated with in-situ techniques for the analysis, quantification and valorisation of the variation in mangrove carbon stocks.
  • Outreach: Ocean literacy (e.g., private and public schools) regarding the importance of mangrove ecosystem and all the services provided to society and impacts due to climate changes and coastal management. Engage with local population, NGO’s and companies to support preservation and restoration activities.
  • Public policy: Contribute to National, Federal, and local public sector actions regarding key coastal managements activities such as PROCOSTA and ORLA project; Contribute to several actions stated in the National Action Plan for Mangroves (PAN Manguezal) coordinated by ICMBio.
