Indonesia's major earthquake last year (2005) tilted Nias Island like a seesaw, disrupting villagers' lives and pointing to future dangers.

At a 31 October gathering of tsunami donors at the United Nations, the World Conservation Union (IUCN) and the U.N. Development Programme are planning to unveil a 6-year, $62 million initiative called Mangroves for the Future (MFF). It's goal is to rehabilitate ecosystems in 12 tsunami hit nations.

Mangrove forests, though essentially common and wide-spread, are highly threatened. Local societies along with their knowledge about the mangrove also are endangered, while they are still underrepresented as scientific research topics. With the present study we document local utilization patterns, and perception of ecosystem change.

The world largest mangroveforest, Sundarbans is situated at the westerncoastal zone of Bangladesh that covers about 40% of the total forest and gives good feedback to the national economy. But for last few years, salinity increasing drastically in this particular region due to sea water intrusion, reduction of fresh water flow and human activities like shrimp farming. In this study both field survey (primary data) and historical
(secondary) data were used to assess the present status of salinity rise in Sundarbans area as well as the effect
