3. Adaptation
The process of adjustment
to actual or expected climate
and its effects. In human
systems, adaptation seeks to
moderate harm or exploit
beneficial opportunities. In
natural systems, human
intervention may facilitate
the process of adjustment to
actual or expected climate
and its effects.
Disaster Risk Management (DRM)
Social processes for designing,
implementing, and evaluating
strategies, policies, and measures to
improve the understanding of
disaster risk, foster disaster risk
reduction and transfer, and
promote continuous improvement
in disaster preparedness, response,
and recovery practices, with the
explicit purpose of increasing
human security, well-being, quality
of life and sustainable development

4. • Climate Extreme
• The SREX report defines climate extreme’ as
“the occurrence of a value of a weather or
climate variable above (or below) a threshold
value near the upper (or lower) ends of the
range of observed values of the variable.
• Risk is the product of the probability that some
event will occur & the adverse consequences
of that event.
• Risk = Probability x Consequence

6. Changes in Extremes
• A changing climate leads to changes in
the frequency, intensity, spatial extent,
duration, and timing of weather and
climate extremes, and can result in
unprecedented extremes.
8. Disaster risk management and climate change adaptation can influence the
degree to which extreme events translate into impacts and disasters
Increasing vulnerability, exposure, or severity & frequency
of climate events increases disaster risk
10. For exposed and vulnerable communities, even
non-extreme weather and climate events can have
extreme impacts
Looking for a good example here.

21. What factors determine capacity to adapt?
The capacity to adapt to climate change is
determined by:
TheThe level of developmentlevel of development
AcAccess to resourcescess to resources
SScientificcientific and technical skills & capacities
Technological advancement
Institutional model
Coordination capacity and mechanisms
22. Linking adaptation to development (1)
• Many of the adaptation options intersect with
vulnerability reduction and development
options that build adaptive capacity and
address the “adaptation deficit” which may be
seen as part of a wider “development deficit”
• Adaptation provide a chance to address “development
deficit” as first (necessary but not sufficient) step.
23. Linking adaptation to development (1)
• SD &Adaptation are mutually reinforcing
• Addressing uncertainty through balancing economic
efficiency/ productivity with resilience/flexibility,
• Through giving due consideration to CC issues, risk
of maladaptation to national development plans will
be avoided.

30. • Many of these low-regrets strategies produce co-benefits, help
address other development goals, such as improvements in
livelihoods, human well-being, and biodiversity & help
minimize the scope for maladaptation.
Low-regrets measures for current DRM are entry points for
addressing projected trends in exposure, vulnerability, as they
have the potential to offer benefits now and lay the foundation for
addressing projected changes
(high agreement, medium evidence).

31. • For instance, dyke systems to control
water flow can reduce hazard exposure by
offering immediate protection, but also
encourage settlement patterns that may
increase risk in the long-term
Attention to the temporal & spatial dynamics of
vulnerability & exposure is important given that the
design & implementation of adaptation &DRM
strategies can reduce risk in the short term, but
may increase vulnerability & exposure over the
longer term. (high agreement, medium evidence)

Editor's Notes
What is called an extreme weather or climate event will vary from place to place in an absolute sense (e.g., a hot day in the tropics
will be a different temperature than a hot day in the mid-latitudes), and possibly in time given some adaptation from society (see
Box 3-1).
• Some climate extremes (e.g., droughts, floods) may be the result of an accumulation of moderate weather or climate events (this accumulation being itself extreme). Compound events (see Section
3.1.3), that is, two or more events occurring simultaneously, can lead to high impacts, even if the two single events are not extreme
per se (only their combination).
Since 1950, extreme hot days and heavy precipitation have become more common
The year 2017 was the fourth warmest year on record over the African land masses since 1950.
There is evidence that anthropogenic influences, including increasing atmospheric greenhouse gas concentrations, have changed these extremes
The character and severity of impacts from climate extremes depend not only on the extremes themselves but also on exposure and vulnerability

Rainfall in Juba amounts to 955 millimetres (38 inches) per year. Between December and February it almost never rains; it rains more than 100 mm (4 in) per month from Avril to October, and the rainiest month is July with 145 mm (5.7 in).
The research finds that, in today’s climate, the average African region experiences one to three “heatwaves” per year. A heatwave is here defined as a period of three or more days where daily temperatures are in the top 5% of the 1971-2000 average for the region.
the damage due to dust storms in China averages at about $6.5 billion per year
dust can cause pneumonia, asthma, Dust storms can take down trees, bury equipment and cause damage to houses.
Dust from the Sahara spread north into Europe 2017, coating ski slopes and Mediterranean cities in orange particles. In western Africa, tons of dust blew out over the Atlantic, perhaps headed for the Americas.

Hurricane Harvey in Texas cost is high as 100 billion dollars, 2017 (ranged from $70 billion to $108 billion ). $130 billion in damage caused by Hurricane Katrina.
During the first week of July 2018, heavy rains in southwestern Japan led to devastating floods and mudslides. The region reportedly experienced three times the amount of normal rain for all of July in a matter of days. Roughly two million people had to abandon their homes and retreat to safety. Over 70,000 emergency response workers are out helping people trapped
Some strategies for effectively managing risks and adapting to climate change involve adjustments to current activities. Others require transformation or fundamental change
It is high time that disaster reduction communities and climate change communities combine efforts
Because by addressing risk factors through an adaptation lens we will be building long solutions
Below average performance of the 2016 short and long rains has led to a severe drought in the Arid and Semi-Arid Lands (ASAL) of Kenya. As a consequence the food insecure population in Kenya has more than doubled over a six-month period.
It is estimated that 2.7 million people in Kenya are now in need of relief assistance, from 1.3 million in August 2016 . This includes 300,000 people in non-Arid and Semi-Arid (non-ASAL) counties affected by crop failures and decline of yields. Most vulnerable are children under 5 years, mothers, the elderly and the sick.
Improved irrigation system- sustainable management of water resources- crop diversification-
One study found that more green space in a city can reduce heat-related deaths by 50%- Other examples of effective low-regrets measures include early warning systems; risk communication between decision makers and local citizens; sustainable land management, including land use and zoning; and ecosystem management and restoration. Other measures include improvements to health surveillance, water supply, sanitation and drainage systems; climate proofing of major infrastructure and enforcement of building codes; and better education and awareness
Locals document in many different ways their experiences with the changing climate, particularly extreme weather events, and this self-generated knowledge can uncover existing capacity within the community-CC presents new realities and new challenges
Appropriate ca be seen as: (Tailored and targeted)
Developed countries are often better equipped financially and institutionally to adopt explicit measures to effectively respond and adapt to projected changes in exposure, vulnerability, and climate extremes than developing countries, although all countries face challenges in assessing, understanding, and acting on projections
Mechanisms include insurance, reinsurance, microinsurance (including weather-index microinsurance), and national and international risk pools
Addressing social welfare, quality of life, infrastructure, and livelihoods, and incorporating a multi-hazards approach into planning and action for disasters in the short term, facilitates adaptation to climate extremes in the longer term.
Strategies and policies are more effective when they acknowledge multiple stressors, different prioritized values, and competing policy goals
