altitude. But the likely changes in the Himalayan region
are still poorly understood, and the actual impacts of
any climate variability on wetlands have barely been
assessed. The interconnectedness of wetlands within
a watershed means that any changes will fl ow on
to the millions of people downstream who depend
on freshwater originating and fl owing through the
Himalayan wetlands.
Changes in the Himalayan wetlands will affect both
the environment and the economy. There is an urgent
need to increase our understanding of the wetlands
ecosystems, the role they play, and the potential
changes and their impact, so that appropriate plans
for management can be developed. Collaborative
approaches will be needed to address the knowledge
gap and to introduce management action to support
the conservation and wise-use of wetlands, and thus
ensure a sustainable future for the water and biodiversity
resources of the Himalayas.
The Himalayan Wetlands Initiative
The Himalayan Wetlands Initiative (HWI) has
developed since 2002 as a forum for integrated
wetland conservation and wise use and so far has
been endorsed by the Governments of India, Myanmar,
Nepal, and Pakistan. The Initiative was endorsed as a
regional initiative of the Ramsar Convention in 2009
