Assessment of blue carbon dynamics in mangrove areas
Climate change, organic carbon, global warming.
Estimates of carbon stock in soils in Brazil are still not satisfactory and are faced with a lack of available information on the amount of organic carbon in soils under different uses and in different regions. This research aims to evaluate the carbon dynamics in mangrove areas in the different compartments of the soil profile in the locality of Vila Velha – Ilha de ItamaracáPE. This work is supported by the theories presented in the Coastal Blue Carbon Manual: Methods for assessing carbon stocks and emissions factors in mangroves, tidal salt marshes, and seagrasses. Conservation International, Intergovernmental Oceanographic Commission of UNESCO, International Union for Conservation of Nature. Arlington, Virginia, USA. The samples were obtained in two areas according to the flood gradient, called flooded area and periodically flooded area, located along the Santa Cruz river channel (Itamaracá/PE). In each core, samples were collected at depths of: 0 – 10; 10 – 20; 20 – 30; 30 – 40; 40 – 50; 50 – 60; 60 – 70; 70 – 80; 80 – 90; 90 - 100 cm. The carbon stock values obtained were subjected to normal distribution, homogeneity of variance and Tukey test.
