With diminished rice harvests, seawater seeping into aquifers and islands vanishing into rising oceans, Southeast Asia will be among the regions worst affected by global warming, according to a report scheduled for release on Monday by the Asian Development Bank.

The rise in sea levels may force the sprawling archipelago of Indonesia to redraw its sea boundaries, the report said.

Thailand is reviving plans for a cartel of major rice producers, a move that could benefit farmers by maintaining soaring rice prices but propagate the food crisis for the poorest consumers in Asia. The Thai government is enlisting the support of Vietnam, the second-largest rice exporter after Thailand, as well as Cambodia, Myanmar and Laos to "help each other control the rice price," according to Thailand's prime minister, Samak Sundaravej.
