Slide 7
What happens when hazards and
stresses impact on people’s lives?
Depending on whether those people are vulnerable or resilient will affect the
outcome. More vulnerable people are less protected from hazards and stresses, they
are not able to cope, and therefore they suffer worse outcomes.
Where people have more resilient livelihoods the impact of a particular hazard event
or stress may be less as they are able to withstand, cope or recover.
Reducing vulnerability and building resilience are therefore important strategies for
poverty reduction.
Slide 10
Hazards and
Climate Projections uncertainty!!!
A great deal of uncertainty exists in the projections.
climate change projections will be difficult and any
projections must be interpreted and used cautiously
as there are limitations of global and regional
climate models and observational datasets for most
regions of the world.
Climate change is a multiplier of risk
Climate change is not a unique hazard but will
interact with many of the underlying drivers of risk
resulting in complex, dynamic situations
Slide 8
Risk of an adverse event or disaster
Risk is a function of the strength of the Hazard
and the Vulnerability of those affected
Risk is often expressed as:
R = H x V/C
Slide 11
CC as Multiplier of Risk
Climate change is not a unique or stand-alone
The changing climate will interact with and
compound existing hazards, stresses and
shocks leading to situations never previously
Weather related events are likely to become
more variable and extreme.
Ecological changes will occur.
Slide 9
Increasing Severity of (some) Hazards
The number of disasters are increasing, particularly hydro-meteorological
disasters (weather events).
Experts believe that some of the increase in reported disasters can be
attributed to increases in extreme climatic events, but the proportion is
very difficult to determine and attribution is even tougher
Impact on hazards (IPCC 2007) Confidence in understanding or projecting
changes in hazards and extremes depends on the type of extreme, as well
as on the region and season.
Frequency and magnitude of hot/cold extremes increasing and projected
to continue. Same with heavy precipitation. No clear trend in tropical
Some suggestion that droughts will increase, but this depends on
definition of drought and the area in question.
Slide 12
Greatest impact is likely to be on
Potential decrease in crop yields, increase in
water scarcity, biodiversity loss
New patterns of vector-borne diseases,
increase in respiratory diseases
In countries with weaker risk-reducing
capacities, underlying risk drivers such as poor
urban governance, vulnerable rural livelihoods
and ecosystem decline will be exacerbated by a
rapid expansion of weather-related risk.
