Tree Hugger - A new report from that [Bangladesh's] Center for Environmental and Geographic Information Services lays it out. The bad news is that 20 million people are likely to be displaced by rising seas. The (sort of) good news is that less land will be fully lost to the water than you might think. The BBC has the details:

"The big thing the report says really isn't that vast areas of land will be fully submerged, but rather that rising seas will allow salt water to get into the water table, disrupting rice production, and that monsoons will flood greater areas than they currently do."

The human impact of all this, according to Cegis' Ahmadul Hassan is that for four months of the year many farmers will have no work, with their lands underwater, and hence migrate to the cities in search of work. That's where the 20 million people displaced figure comes from.

Nearly half of Bangladesh's rice production is 'monsoon' rice and much of that is grown in areas which will no longer be cultivatable. So, in addition to people migrating to cities, food availability could decline as well.
