The opposition Labor Party has called
on the Australian government to prepare for a
"flood" of refugees from the Pacific
Islands as sea level rises. "Australia needs to
establish an international coalition, particularly
from Pacific rim countries, so that when a country
does become uninhabitable Australia does its fair
share," argued
Anthony Albanese, opposition environment
spokesman. "The Howard government can't
continue to simply pretend that this is an issue that
doesn't have to be dealt with in our
region." Moreover, "we need to establish a
United Nations charter in terms of refugee
recognition which isn't there at the moment in
terms of environmental refugees," he
concluded.

The Australian government was quick to dismiss the
call for action. "To start planning an
evacuation of the Pacific is really a ludicrous
policy," responded environment minister
Ian Campbell. "We've established the
world's leading sea-level change monitoring
equipment across the Pacific, in cooperation with our
Pacific neighbours and we work on a range of
adaptation measures with them. But to be planning in
the year 2006 for something that may not happen for
20, 30, 40 years, or may not happen at all (is
wrong), when there are so many things that we need to
be doing." Nevertheless, the Labor plan was
welcomed by Pacific islanders. "Tuvalu does
support the development of new policies that support
the Pacific by any future Australian
government," said Prime Minister Maatia
Toafa. "The proposals... are very much in
line with the Marshall Islands thinking," said
the foreign minister Gerald Zachios of the Marshall
Islands.

Research by a multi-institutional team has
shown that large-scale plantations, while
offsetting carbon emissions, can have adverse
effects on the environment. "We believe that
decreased stream flow and changes in soil and water
quality are likely as plantations are increasingly
grown for biological carbon sequestration,"
the ten authors concluded in a paper in the journal
Science. The study, led by Duke
University, was based on field data and
modelling.
|
"After about ten years' growth under
intensive plantations, about one-in-eight of the
streams that were in the areas that we studied had
no flow for a year or more, and overall there was a
50 per cent reduction in stream flow,"
reported Damien
Barrett from CSIRO in Australia.
Using plantations as a means of managing the carbon
concentration in the atmosphere is "about
trade-offs, it's about maximizing carbon
sequestration benefit and minimizing the adverse
flow-on effects by locating plantations in the
landscape," he concludes.

A new study concludes that the world is running
out of fertile land and that food production may fail
to keep up with the planet's growing population.
The results are based on maps of global land use
derived from satellite information and agricultural
census data.
Navin Ramankutty of the University of
Wisconsin-Madison in the United States said that
"the maps show, very strikingly, that a large
part of our planet (roughly 40 per cent) is being
used for either growing crops or grazing
cattle." "One of the major changes we see
is the fast expansion of soybeans in Brazil and
Argentina, grown for export to China and the
EU," he continued.
|
There is concern that there is little space left
for agricultural expansion. "Except for Latin
America and Africa, all the places in the world where
we could grow crops are already being cultivated. The
remaining places are either too cold or too dry to
grow crops," warned Ramankutty. The project will
continue with the development of the Earth
Collaboratory, an internet-based databank drawing on
the expertise of scientists, environmentalists and
the public world-wide.
