The above map on climate impacts on biodiversity,
based on a study by the University
of Arizona, shows regions that have experienced droughts
lasting a decade or longer (labelled "DD") as well as regions
with abrupt shifts in hurricane frequency (labelled "HT").
The expected impacts on biodiversity due to climate change
(including variability) will vary from region to region.
The frequency, intensity, extent and locations of climate-induced
disturbances will determine the rate at which existing ecosystems
are affected.
UNDP Programme Officers are encouraged to draw on the latest
scientific findings on the vulnerability of biodiversity
to climate change when formulating adaptation projects.
The "Relevant Links" section below provides some
starting points for additional information.
Overview
Projected impacts on biodiversity due to climate change, extreme
climatic events and climate variability include changes in:
-
the timing of reproduction in animals and plants;
-
the length of the growing season;
-
species distribution and population sizes,
including possibility of extinction – especially
species with limited climatic ranges and restricted habitat
requirements;
-
frequency of pest and disease outbreaks;
-
species migration – movement of species poleward
or upward in elevation from their current location.
Adaptation-related projects on biodiversity
should focus on maintaining or strengthening the resilience
of species and/or ecosystems threatened by climate change.
Projects should reflect dynamic, long-term response measures.
