Impact of Climate change in the Mangrove Distribution across the Indian Coast

Abstract:

India is a tropical country surrounded by oceans in three sides i.e. Bay of Bengal in east, Arabian Sea in west, north Indian Ocean in south and by the large mountain system the Himalayas in north. Due to large coast line there is wide range of Mangroves in the coastal India. Mangroves are generally salt tolerant as well as rainfall and temperature dependent, so in this study an approach is being made for the trend analysis of the coastal weather parameters like Temperature, Rainfall, wave pattern and tide in the coastal region of India to understand the climate variability both in multiple spatial and temporal scale and also to correlate the impact of climate change on the Mangrove distribution. The weather parameters from multiple sources like satellite and reanalysis data are being analyzed in terms of the inter annual variability and trend analysis. The corresponding mangrove distribution also monitored and the correlation analysis of the weather parameters and the mangrove population are presented. The study is being carried out in country as a whole as well as along the state coast lines. Comparison of the distribution of mangrove as well as the associated parameters along the eastern and western coast are compared and it is found that there is higher variability in the mangrove distribution.
