abstract = "Land use and management activities have a substantial impact on
carbon stocks and associated greenhouse gas emissions and
removals. However, it is challenging to discriminate between
anthropogenic and non-anthropogenic sources and sinks from land.
To address this problem, the Intergovernmental Panel on Climate
Change developed a managed land proxy to determine which lands are
contributing anthropogenic greenhouse gas emissions and removals.
Governments report all emissions and removals from managed land to
the United Nations Framework Convention on Climate Change based on
this proxy, and policy interventions to reduce emissions from land
use are expected to focus on managed lands. Our objective was to
review the use of the managed land proxy, and summarize the
criteria that governments have applied to classify land as managed
and unmanaged. We found that the large majority of governments are
not reporting on their application of the managed land proxy.
Among the governments that do provide information, most have
assigned all area in specifc land uses as managed, while
designating all remaining lands as unmanaged. This designation as
managed land is intuitive for croplands and settlements, which
would not exist without management interventions, but a portion of
forest land, grassland, and wetlands may not be managed in a
country. Consequently, Brazil, Canada and the United States have
taken the concept further and delineated managed and unmanaged
forest land, grassland and wetlands, using additional criteria
such as functional use of the land and accessibility of the land
to anthropogenic activity. The managed land proxy is imperfect
because reported emissions from any area can include
non-anthropogenic sources, such as natural disturbances. However,
the managed land proxy does make reporting of GHG emissions and
removals from land use more tractable and comparable by excluding
fuxes from areas that are not directly infuenced by anthropogenic
activity. Moreover, application of the managed land proxy can be
improved by incorporating additional criteria that allow for
further discrimination between managed and unmanaged land.",
