Accelerated sea-level rise and the effects on coastal areas represent one of the most important impacts of global climate warming as a large part of the world's population and food production is situated along low-lying coasts. Coastal nations of the world should now be planning for one-half to a meter rise in sea level during the next century. While the actual extent of sea rise realized may be larger or perhaps smaller, this amount establishes a reasonable baseline for coastal zone planning activities. With respect to actual measures, priority should be given to projects that are beneficial to presently existing problems in coastal areas.
