The key findings are outlined:
Finding 1: The best estimate of the cost of adaptation in developing
countries is between $60-$100 billion a year by 2030, although this is
subject to considerable uncertainty.
Finding 2: Current flows of adaptation finance are significantly lower
than future needs; there is a need to progressively scale up flows of
adaptation investment from all sources (public, private, domestic and
international) in the near term.
Finding 3: Uncertainty over climate impacts is not a reason for inaction
on adaptation today; but does demand that adaptation decisions are made
Finding 4: There are complementary roles for the public and private
sector in supporting adaptation activities; standard economic analysis
can be used to help delineate the appropriate role for each.
Finding 5: Given limited resources for international climate finance for
adaptation, resources may be optimally focussed in countries with high
adaptation costs and where adaptation actors have limited access to
finance. The limited evidence suggests that adaptation finance is not
being prioritised in this way.

for International Development (DFID) Adaptation Knowledge and Tools
programme and published through Evidence on Demand.
The Adaptation Knowledge and Tools programme is a DFID-funded programme
intended to maximise the effectiveness of UK and international
investment in climate change adaptation and resilience. The knowledge
and tools generated through this programme are expected to promote
greater understanding of what constitutes best practice in adaptation,
as well as better international cohesion and coordination around
adaptation. Through these entry points the programme expects to increase
the quality of international and UK adaptation programming and reduce
