Connections between mountain
ecosystems to mitigate climate change impacts
Papallacta, Ecuador,
November 17, 2006 – To mitigate the impacts of
climate change on
mountain ecosystems, a global network of mountain experts urges the
world to better protect and restore lands that connect mountain habitats.
“Connectivity
is necessary as a defence against climate change, to protect sources of
drinking water, to ensure the
survival of wildlife and to preserve resources on which mountain communities depend”,
says David Sheppard,
Head of the IUCN Global Program on Protected Areas.
Mountains cover 20 percent of the planet’s terrestrial
surface, are the source of to more than half of the Earth’s
fresh water, are major centres of global biological and cultural
diversity, and are
sources of inspiration and spirituality. Yet, mountains have low
resilience and high vulnerability to change.
“Mountains are one of the
ecosystems most threatened by climate change,”
notes Dr. Fausto
Sarmiento, a professor of mountain geography and Deputy Vice Chair of
the World Commission of Protected Areas (WCPA) Mountains Biome.
“As climates
warm, mountain species are forced to move higher up, glaciers disappear
at an alarming pace, and fresh water resources are dramatically affected,”
he adds.
In recent decades, parks and other protected areas have been the major
tool for maintaining mountain habitats. However, isolated protected
areas, regardless of their size, are insufficient to protect the
species requiring very large landscapes, or which migrate between upper
elevation and lower elevation environments.
“We need to
think big to secure the future for biological diversity,”
says Graeme Worboys,
Vice Chair of the WPCA Mountains Biome. “Restoring and protecting the
habitats that link protected areas is a way of greatly increasing the
ability of wild species to move in adaptation to climate
change,” he notes.
Humans are also dependent on mountainous regions. The Food and
Agriculture Organization of the United Nations estimates that about 770
million people, or about 12 percent of the world’s
population, live in mountain areas.
“Hillside
agricultural ecosystems sustain millions of small farmers, most of whom
live in marginalized communities,” states Lawrence Hamilton, Senior Advisor
to the Mountains
Biome of the WPCA. “About half of these ecosystems
show signs of serious environmental degradation, resulting from
deforestation, overgrazing and harmful agricultural practices,”
he concludes.
The 40 participants at the Mountain Connectivity Conservation
Management workshop in Papallacta representing 17 countries signed a
declaration urging communities, governments, non-governmental
organizations, businesses, religious groups, academic and research
institutions to take coordinated action to engage in connectivity
conservation in and around mountain regions. The Papallacta Declaration
will be presented to Minister Alfredo Carrasco, Vice Minister of
Environment for Ecuador, who opened the conference, as well as other
governments and agencies around the world. The work done at the
workshop will culminate in a book on Mountain Connectivity
Conservation, to be published in 2008.
