Temporal Analysis of the Mangrove Forest at the Mocajuba River Hydrographic Basin-Pará

Mangrove forests are ecosystems naturally susceptible to environmental stresses, such as rising sea level and coastal erosion. However, the anthropic stresses, such as real estate speculation, deforestation and water pollution, put at risk this environment’s stability, interfering with its balance. The present work’s aim is to perform a temporal analysis of the mangrove forest that is a part of the Mocajuba river hydrographic basin and its buffer zone, as well as identifying natural and anthropic stresses to which the mangroves are susceptible. It was verified that the mangrove forest areas presented a substantial reduction between 1984 and 1999, and a small loss between 1999 and 2018. Thus, in the mangrove forest buffer zone, the anthropized areas increased while the forest areas decreased, demonstrating the deforestation in these areas. It can be concluded that the mangrove forest in the study region present a regression.
