Q

What is adaptation?

A

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 adjustment to expected climate and its effects

Planned adaptation

A

Adaptation that is the result of a deliberate policy decision, based on an awareness that conditions have changed or are about to change and that action is required to return to, maintain, or achieve a desired state.

Q

Adaptation is not new because

A
  • Societies have always attempted to make the best use of their climatic conditions
  • Societies have also always tried to adapt to changes
  • Adaptation includes practices from well-established domains e.g. disaster risk management, coastal management, spatial planning, urban planning

A
  • Unprecedented climate conditions
  • Unprecedented rate of change
  • Unprecedented knowledge
  • Unprecedented methodological challenges.
  • New Actors
  • New measures.
17
Q

Questions for Adaptation to take place

A
  • Climate sensitive domain (agriculture, water, mgmt.?)
  • Climate hazard (observed/expected change: changes in mean, extreme)
  • Predictability of the climatic change (is confidence in change high → low?)
  • Who are the actors (government, private sector, civil society?)
  • Timing (reactive or anticipatory?)
  • Planning horizon (few months → many decades?)
  • Form (What measure: technical, institutional, educational, behavioural?)
  • What non-climatic conditions also impact the adaptation decision? (these might be environmental, economic, political, cultural)
18
Q

Preconceptions for effective adaptation

A
  • Awareness of the problem – assessing and communicating vulnerability
  • Availability of effective adaptation measured – triggering research that may lead to new adaptation measures
  • Information about these measures – identifying and assessing effective adaptation options
  • Availability of resources for implementing these measures – evaluating co-benefits; efficient use of resources; additional resources?
  • Cultural acceptability – how acceptable is proposed adaptation? Is it fair, equitable, legitimate?
  • Incentives for implementing these measures – obstacles, barriers?
19
Q

Energy Saving in building

A

According to CISL ”there is potential for energy savings of 50-90% in existing and new buildings.

20
Q

Population in cities

A

More than half the world’s population now lives in cities, making urban areas more important than ever for climate change adaptation. (Rose, 2014)

21
Q

Investment needed in energy sector from rising 2 degrees C

A

An estimated investment of USD $190-$900 billion a year to 2050 is needed for the energy sector to keep temperatures from rising 2 degrees C. An estimated $340 billion was invested in reducing GHG emissions in 2011/12.
(Rose, 2014)

22
Q

World’s oceans acidity

A

The world’s oceans have seen roughly a 30% in acidity since pre-industrial times. (Rose, 2014)

23
Q

Research and policy aspects of climate change has focused largely

A

on the material aspects of climate change, including risks to lives and livelihoods, the costs of decarbonizing economies and the costs of impacts on various sectors of the economy (Adger et al, 2012)

24
Q

Climate change effect on cultures

A
  • The expected impacts of climate change will affect cultures in diverse ways.
  • Few cultures will escape the influences of climate change in these coming decades.
  • The loss of access to places as a result of coastal inundation for example will have a clear impact on culture. When people are displaced from places that they have value, there is strong evidence that their cultures are diminished.
    Adger et al, 2012
25
Q

Place attachment

A
  • Individuals with a strong attachment to their community are often unwilling to migrate to maintain their income levels because they are reluctant to leave behind their social and emotional support groups and adapt to a new community
26
Q

Fussel (2007) - Adaptation measures

A

Adaptation to climate change involves a very broad range of measures directed at reducing vulnerability to a range of climatic stimuli

27
Q

Fussel (2007) - Adaptation and risk management

A

– Adaptation planning shares many common features with risk management but involves unprecedented methodological challenges because of the uncertainty and complexity of the hazard.

28
Q

Fussel (2007) - Adaptation context-specific

A

Adaptation to climate change is highly context-specific, because It depends on the climatic, environmental, social and political conditions in the region and sector.

29
Q

Fussel (2007) - Adaptation - adaptation principles

A

– Although there is no single approach for assessing, planning and implementing adaptation to climatic change, some robust adaptation principles have nevertheless emerged.

30
Q

Fussel (2007) - Adaptation assessment

A

– Adaptation assessment has become more inclusive over time, linking future climate change with current climate risks and other policy concerns.

31
Q

Fussel (2007) - Adaptation consideration of global climate change

A

– Consideration of global climate change is particularly important for decisions with a long planning or policy horizon

32
Q

Fussel (2007) - Adaptation and impacts of climate change

A

Adaptation cannot avoid all impacts of climate change, because of important fundamental and practical, constraints. Adaptation to climate change is, therefore, no substitute for mitigation of climate change.

33
Q

High social capital and adaptation

A

High social capital contributes to both positive public health outcomes and to climate change adaptation.
There is an expectation that social capital could reduce vulnerability to risks from the impacts of climate change in the health sector. Wolf et al (2010)

34
Q

Strong social networks

A

Strong social networks have been said to support individuals and collective initiatives of adaptation and enhance resilience. Wolf et al (2010)

35
Q

Barriers to adaptation shaped by social networks

A

This research suggests that barriers to adaptation can be shaped by social networks.
Elderly and social contacts’ perception of health risks from heat waves, and their consequences, are an example of barriers to proactive anticipatory adaptation.
Wolf et al (2010)

36
Q

Adger and Barnet (2009): Four reasons for concern about adaptation to climate change - Adaptation smaller than imagined.

A
  • Scale of change and interconnectedness of impacts may be such that the window of opportunity for adaptation is smaller than previously imagined.
  • Recent research that projects future concentrations of GHG based on emission trends since 2000 suggests that there will have to be a major turnaround in policy, planning, and behavior to avoid an atmospheric concentration that poses a significant risk of global mean warming of 2 degrees C or beyond (Meinshausen et al, 2009)
37
Q

Adger and Barnet (2009): Four reasons for concern about adaptation to climate change - adaptive capacity and action taken

A
  • The adaptive capacity will not necessarily translate into action.
  • Robert Repetto (2009) has termed this ‘adaptation myth’ – he argues that the US in effect decided that its economy is unvulnerable to climate change impacts and will be able to adapt to climate change.
38
Q

Adger and Barnet (2009): Four reasons for concern about adaptation to climate change - sustainable actions in place?

A
  • The extent to which actions already in place are not sustainable
  • In southern Australia the response of governments to declining streamflows – which in extreme cases such as Perth have been 25% of long-term averages (Preston and Jones, 2006) – has been to trade energy for increased water supply
39
Q

Adger and Barnet (2009): Four reasons for concern about adaptation to climate change - Social context of adaptation

A
  • The metrics that may be used to determine the goals of adaptation, the measures of its success, and that trade-offs that may be involved can be understood only in terms of the social context in which adaptation takes places.
  • Communities value things differently and these must be taken into account if adaptation is to be effective, efficient, legitimate, and equitable (Barnett and Campbell, 2009).
