As world governments gathered in Uzbekistan Monday for the United
Nations conference on migratory species, they centered the theme
"Nature Knows No Borders"—an idea that a new landmark report said
must take hold across the globe to push policymakers in all
countries and regions to protect the billions of animals that travel
each year to reproduce and find food.
The Convention on the Conservation of Migratory Species of Wild
Animals (CMS) marked the opening of the 14th Conference of the
Parties (CMS COP14) to the United Nations biodiversity treaty by
releasing the first-ever State of the World's Migratory Species
report, showing that nearly half of migrating species are declining
in population.
The crisis is especially dire for more than 1 in 5 species that are
threatened with extinction, and 70 species listed under the CMS
which have become more endangered, including the steppe eagle, the
Egyptian vulture, and the wild camel.
The populations of nearly all species of fish listed in the U.N.
treaty, including sharks and rays, have declined by 90% since the
1970s.
The two biggest drivers of endangerment and threatened extinction
are overexploitation—including incidental and intentional
capture—and habitat loss, and both are directly caused by human
activity.
Seven in 10 CMS-listed species are threatened by overexploitation,
while 3 in 4 of the species are at greater risk of dying out due to
habitat loss, as humans expand energy, transportation, and
agricultural infrastructure across the globe.
The climate crisis and planetary heating, pollution, and the spread
of invasive species—thousands of which are introduced by humans—are
also major threats to migratory species, the report says.
"Unsustainable human activities are jeopardizing the future of
migratory species—creatures who not only act as indicators of
environmental change but play an integral role in maintaining the
function and resilience of our planet's complex ecosystems," said
Inger Andersen, undersecretary-general of the U.N. and executive
director of the U.N. Environment Program (UNEP). "The global
community has an opportunity to translate this latest science of the
pressures facing migratory species into concrete conservation
action. Given the precarious situation of many of these animals, we
cannot afford to delay."
Migratory species "reinforce" the fact that nature does not observe
borders put in place by humans, Andersen added in a video posted on
social media, and humans must work across borders to ensure these
species are protected.
According to the report, nearly 10,000 of the world's key
biodiversity areas are crucial for the survival of migratory
species, but more than half are not designated as areas that must be
conserved—and 58% are under threat due to human activities.
Mapping and taking adequate steps to protect "the vital locations
that serve as breeding, feeding, and stopover sites for migratory
species" is a key priority, said the CMS in a statement.
"Migratory species rely on a variety of specific habitats at
different times in their lifecycles," said Amy Fraenkel, CMS
executive secretary. "When species cross national borders, their
survival depends on the efforts of all countries in which they are
found. This landmark report will help underpin much-needed policy
actions to ensure that migratory species continue to thrive around
the world.”
In addition to increasing understanding of migration paths and
minimizing human infrastructure in the pathways, the report
recommended that policymakers "strengthen and expand efforts to
tackle illegal and unsustainable taking of migratory species"; scale
up efforts to tackle climate change and light, noise, chemical, and
plastic pollution; and consider expanding CMS listings to include
more at-risk migratory species in need of international attention.
"There are many things that are needed to be done on addressing the
drivers of environmental change, such as agriculture for habitat
destruction, the sprawl of cities, we have to look at rail, road,
and fences," said Fraenkel. "One of the most important things for
migratory species is something we call ecosystem integrity: they
need particular sites to breed, feed, and travel. If those sites
cannot be accessed or don’t exist any more, then it's obviously
going to be detrimental."
The report focused on 1,189 migratory species identified by the U.N.
as needing protection, but found that another 399 migratory species
are either threatened or near threatened with extinction.
"People might not realize that whales, lions, gorillas, giraffes,
and many birds are migratory species," Fraenkel said.
At the opening ceremony of CMS COP14, Andersen called on
policymakers to live up to the conference's theme "by ensuring free
passage of migratory species and by ensuring that, through
multilateralism, we reach a hand across every border to ensure
long-term sustainability, for people and for planet."
Reversing population decline is possible, the report emphasized,
pointing to coordinated local action in Cyprus that reduced illegal
bird netting by 91% and "hugely successful" conservation and
restoration work in Kazakhstan, "which has brought the saiga
antelope back from the brink of extinction."
"I ask parties to consider how to work in harmony with other
processes for mutually assured success," said Andersen, "all in the
interests of sustainable economies and societies."
