Evaluación del estado de salud de los bosques de manglar en el archipiélago de Jambelí, mediante uso de índices espectrales.

Abstract

Abstract: This study was carried out in the archipiélago de Jambelí, where mangrove areas obtained by means of the CMRI vegetation index were delimited, which allows the mangrove of other vegetation to be discriminated against. A total of 6711.81 acres of mangroves were obtained, of which 70.33% is under Sustainable Use and Mangrove Custody Agreements (AUSCM). A time series analysis was carried out using the Mann-Kendall (MK) test for Enhanced Vegetation Index /EVI), from 2001 to 2019, finding that approximately 70% of the vegetation is increasing its photosynthetic activity. Linear relationships showed that the distance to shrimp influences the decrease in the MK trend, showing values of r2 = 0.89. However, the distance to mangrove concessions influences a much smaller degree, obtaining an r2 = 0.07, thus released that the distance to concessions is not the only variable that is influencing the increase in MK trends, which generates a new question that is whether climate variables influence the increase in vigor?
