Farmers along the Gujarat coast should have been rejoicing at the prospect of a timely monsoon. Instead, they have suddenly become gloomy after unnaturally aggressive high tides have filled their fields and ponds with saline seawater. Many fear a drinking water crisis as their ponds, meant to store fresh rain water, are now brimming over with saline water. Farmers say they may not be able to cultivate anything for years together as their fields have become saline.

Time to check salinity intrusion in the Sundarbans Mohammad Asrafur Rahman Sundarban Mangrove forest of Bangladesh covers an area of about 6017 sq. km which is 62 percent of its total area whereas other 38 percent is situated in the West Bengal province of India. The average elevation from the mean sea level varies between 0.9 and 2.1 m. The rise in sea level and availability of less fresh water particularly during winter will cause inland intrusion of saline water.

The Aral Sea in Central Asia was the fourth-largest lake on the planet in 1960. By 2007 it had shrunk to 10 percent of its original size. Widespread, wasteful irrigation of the deserts along the Amu and Syr rivers, which feed the Aral, cut the freshwater inflow to a trickle. Nevertheless, a dam built in 2005 has helped the northernmost lake expand quickly and drop substantially in salinity.
