Resumen:
For millennia people have valued coastal environments for
their rich soils, harvestable food resources and access to the
oceans. From ancient times to the present, cities and ports
have flourished at the coast and this value continues into the
twenty-first century. With globalisation and international
trade becoming central to many world economies, coastal
populations have continued to grow. In 2003, in the USA
approximately 153 million people (53% of the population)
lived in coastal counties, an increase of 33 million people
since 1980 (Crossett et al., 2004). By the year 2008, coastal
population in the USA is expected to increase by approximately
7 million. Eight of the worlds top ten largest cities
are located at the coast. According to the UN Atlas of the
Coast (www.oceansatlas.org/), 44% of the worlds population
(more people than inhabited the entire globe in 1950)
live within 150 km of the coast and in 2001 over half the
worlds population lived within 200 km of a coastline.
Coastal cities also have higher rates of growth than many
other areas. Clearly the massive population now existing
along the world coast and the rapid growth it is experiencing
induce a major stress on the local and regional geomorphology
as well as on the local resource base.
