Coasts under threat, fisheries vulnerable-UN study
ITALY: June 5, 2008
ROME - High food prices may add pressure for more fishing along coasts where
the environment faces threats from pollution and climate change, a UN
University report said on Wednesday.
It said 40 percent of all people lived within 50 km (30 miles) of coasts and
that governments needed to work out better policies to safeguard resources.
"The decline is terminal, unless we introduce much more effective management
immediately," said the study by the university's International Network on
Water, Environment and Health (INWEH).
"This is one more voice added to the chorus about how bad the situation for
the world's coasts is," Peter Sale, INWEH assistant director, told Reuters.
Fixing the problems "do not mean spending more money but spending it more
wisely".
High prices for foods such as wheat and rice may mean people press for more
fishing, he said. A conclusion in the report said "management of fisheries
is failing".
"Even in a developing country that critically needs more food it is better
to have a management system in place that means they have some fish rather
than none at all," he said.
The study said world fish catches peaked in the late 1980s with larger
species, such as tuna and swordfish, being progressively fished out.
A UN summit in Rome from June 3-5 is considering ways to defuse a world food
crisis which threatens up to 1 billion people with hunger, caused by factors
including rising populations, high oil prices and a shift to biofuels.
"Coastal marine systems have declined progressively in recent decades due to
the growth of human populations and their demands on the marine environment
and resources," the report said. "Bays and estuaries, sea grasses, and
mangroves and wetlands have suffered dramatically in the past 50 years."
Run-off from fertilisers were adding to "dead zones" along the coasts and
corals could be under threat from warmer oceans.
The UN climate panel projected last year that world sea levels will rise by
between 18 and 59 cm (7-23 inches) this century due to heat-trapping
emissions of greenhouse gases, mainly from burning fossil fuels that are
melting ice sheets.
