Abstract

Threat to mangrove forest through climate change: The earlier perception of mangrove ecosystems as ugly, impenetrable and morbid swamp areas was probably one of the reasons for the blindfold clearance of more than 30% of their original worldwide inventory. The human pressure on mangrove forests continues by conversions into shrimp farms for aquaculture, building areas, plantations, etc. Only in recent times their internal valuable resources are appreciated. In view of the large impacts by human activities it is difficult to assess possible effects of climate changes. Based on available evidence, of all the climate change outcomes, relative sea-level rise and the increase of extreme events in the atmosphere may be the greatest threat to mangroves. Both change the sediment and nutrient cycles in the mangrove forests. There is less certainty over other climate change outcomes and mangrove responses. Since the quaternary mangroves have survived large sea level and other environmental changes. However, because of the manmade alterations they are today more vulnerable than in their natural state. The discussion on the effects of the changing climate must include the possible reactions of the local population.
