The world has failed to meet the target set by international leaders
to reduce the rate of biodiversity loss by this year, experts will
announce next month.
Instead, a coalition of 40 conservation
organisations claims there have been "alarming biodiversity declines",
and that pressures on the natural world from development, over-use and
pollution have risen since the ambition was set in the 2002 Convention on Biological Diversity.
first formal assessment of the target, published today in the journal
Science, will be the basis of a formal declaration by the CBD in
Nairobi on 10 May, at which governments will be pressed to take the
issues as seriously as climate change and the economic crisis.
growing number of studies have shown that it is almost impossible to
calculate the value of the "ecosystem services" from the natural world,
from food, rich soil and fuel for local people, to clean air and water,
and plants used for the international pharmaceutical industry.
1970 we have reduced animal populations by 30%, the area of mangroves
and sea grasses by 20% and the coverage of living corals by 40%," said
Professor Joseph Alcamo, chief scientist of the United Nations
Environment Programme, one of the contributing organisations.
losses are clearly unsustainable, since biodiversity makes a key
contribution to human well-being and sustainable development."
Science study compiled 30 indicators of biodiversity, including changes
in populations of species and their risk of extinction, the remaining
areas of different habitats, and the composition of communities of
plants and animals.
analysis shows that governments have failed to deliver on the
commitments they made in 2002: biodiversity is still being lost as fast
as ever, and we have made little headway in reducing the pressures on
species, habitats and ecosystems," said Stuart Butchart, the paper's

"Our data show that 2010 will not be the year that
biodiversity loss was halted, but it needs to be the year in which we
start taking the issue seriously and substantially increase our efforts
to take care of what is left of our planet."
successful policies that have helped preserve and sometimes restore
species and ecological areas are also highlighted in Science, and
politicians are called on to fund more such initiatives.
include new protected areas, including the Juruena national park in
Brazil; projects leading to the recovery of species such as the
European bison, and even animals on the brink of extinction, such as
the black stilt, a wader bird from New Zealand.
the CBD's executive secretary, said: "While many responses have been in
the right direction, the relevant policies have been inadequately
targeted, implemented and funded. Above all biodiversity concerns must
be integrated across all parts of government and business, and the
economic value of biodiversity needs to be accounted for adequately in
The failure to meet the CBD target will not be
a surprise to experts or policymakers, who have warned for years that
too little progress was being made. Last month the head of the IUCN
species survival commission, Simon Stuart, told the Guardian that for the first time since the dinosaurs species were believed to be becoming extinct faster than new ones were evolving.
Natural England, the government's countryside agency, also warned that more than two species a year were becoming extinct in England.
weeks ago, in another paper in Science, the eminent ecologist E O
Wilson led calls from the International Union for the Conservation of
Nature and nine other conservation groups for a "barometer of life" to track the changing fortunes of 160,000 of the world's 2m known species.
