Long-Term Dynamics of Mangrove Forest in Andaman, India

Abstract

Mangrove forests in Andaman district, India are chosen for investigation based on its high diversity and rich species composition. The long-term understanding of distribution and dynamics of mangrove forest in Andaman region is still inadequate. This study aims to generate the detail changes of mangroves during past decades. It also focuses on the key factors responsible for spatial changes during the period. Historical database are generated from past literatures and coupled with satellite image information to prepare the mangrove dynamics. This study finding revealed that the mangrove deforestation is high due to natural as well as anthropogenic stresses specially the impact of seismic and climate change and reclamation of land, agriculture pressure, and pollution. The outcomes of the study have been checked during field but due to the convenience of accessibility conditions only eastern part of Andaman island is considered for validation.
