Estimativa do Anidrido carbónico sequestrado acima do solo pelas árvores do mangal de Inhangome província da Zambézia, Moçambique

Abstract

In the context of climate change and its mitigation, mangrove forests are prominent as they sequester and retain carbon in various parts of the forest, causing mangroves to store more carbon than other forests. However, little is known about carbon dioxide stocks by the different species of this ecosystem. The present study was carried out in the Inhangome mangrove, in the Zambézia province, central Mozambique, in order to know the amount of carbon dioxide stored above the ground by the trees of the Inhangome mangrove forest. For this purpose the sociological phytophysics was determined, biomass was calculated and carbonic carbon and anhydride stored in mangrove were calculated. 4 Species of more were identified namely Avicennia, Ceriops tagal, Rhizophora mucronata, and Xylocarpus granatum and the dominant species is Avicennia marine. The density of the trees and the basal area were 361 trees / ha and 0.66 m2 / ha. The total biomass of the mangrove was 8.25 t / ha, where Avicenna marine species had the highest stock that was 2 t / ha of carbon and 8.67 t / ha of carbon dioxide, followed by Xylocarpus granatum with 0.90 t / ha of carbon and 3,31 t / ha of carbon dioxide, the lowest stock was verified in Ceriops tagal with less than 0.5 t / ha of carbon and 1.46 t / ha of carbon dioxide. These data demonstrate that Inhangome mangroves have potential for carbon sequestration and need to provide a baseline for monitoring and control in order to increase carbon stocks.
