Change may provide a means to enhance
the quality and timeliness of the inter actions
between scientists and policy-makers at
national scales and above. The GLOBE Inter-
national Commission on Land Use Change
and Ecosystems, made up of senior legisla-
tors from the G8+5 and several developing
countries, provides another opportunity to
bring policy-makers and scientists together.
Similar initiatives will also be needed at the
The United Nations will convene a sum-
mit in 2010 to consider the second 5-year
review of the MDGs and to catalyze action
ahead of the 2015 MDG target year. We must
advise policy-makers and civil society organi-
zations on the most critical initiatives needed
to achieve the MDGs while preserving biodi-
versity and ecosystem services.

n response to global declines in biodiver-
sity, some 190 countries have pledged,
under the Convention on Biological
Diversity (CBD), to reduce the rate of bio-
diversity loss by 2010 (
). Moreover, this
target has recently been incorporated into
the Millennium Development Goals in rec-
ognition of the impact of biodiversity loss on
). Timely information on
where and in what ways the target has or has
not been met, as well as the likely direction
of future trends, depends on a rigorous, rele-
vant, and comprehensive suite of biodiversity
indicators with which to track changes over
time, to assess the impacts of policy and man-
agement responses, and to identify priorities
for action. How far have we come in meeting
these needs, and is it sufﬁ
