Data and Statistics: Depleting Mangroves

According to a FAO report in 2005, global mangrove coverage has fallen from 18.8 million hectares in 1980 to 15.2 million by the end of 2000, which is approximately 20% of the global mangrove area in Asian in 1980.

The graph below shows the area of mangroves that were destroyed in India between 1987- 1997. This is a huge drop!

If we look at thailand, we can see that when there is a decrease in the area of mangroves, there is an increase in area for shrimp farms.
