9 “To a Hammer, Everything Looks Like a Nail” Methods or models do not provide answers, but can help us gain insights The first step is to consider the question(s) being asked.

10 Some Questions to Begin a V&A Assessment What is of concern? a)Food production, water supply, health? b)Concerns may not be expressed in climate terms, e.g. extreme temperatures, but in terms of consequences of climate change for people. Who may be affected? How far into the future is of concern? Note: concerns may focus on current risks (which could be made worse by climate change).

11 For what purpose is the assessment to be used? a)Raising awareness (education)? b)Policy making (e.g. to inform a particular decision). What kind of output is needed? Some Questions to Begin a V&A Assessment

12 What resources are available to conduct the study? a)Money b)Staff c)Expertise d)Data e)Regional linkages f)Relationships with donors and development partners. How much time is available? Additional Questions Before Starting the V&A Assessment

13 Key Factors in Determining How to Conduct Your Study You should not begin with the methods or models you have in hand, but with “the previous questions. Select methods and models that best help you answer the questions.

14 Different Questions May Lead to Different Approaches Questions about how climate change may affect resources may lead to analysis of long-term impacts (e.g. out to 2100). Questions about adaptation may lead to analysis of vulnerability within a planning horizon (e.g. 5 to 50 years)

15 Who is Asking the Question(s) May Determine How the Work is Done Some may be content with research that is conducted by the researchers Others may wish for a hands-on approach: e.g. Involve stakeholders in conducting the analysis and also shaping outputs by helping with sectoral and geographic prioritization.

16 1.What information is needed? 2.When is the information needed? 3.Who needs the information? Bottom Line:

17 Impacts of Climate Change Impact is typically the effect of climate change: a)For biological systems, it can be change in productivity, quality, population, or range b)For societal systems, it can be a change in income, morbidity, mortality, or other measure of well-being.

18 Adaptation Adaptation refers to initiatives and measures to reduce the vulnerability of natural and human systems, against actual or expected climate change effects. Various types of adaptation exist, e.g. anticipatory and reactive, and autonomous and planned. Examples include: raising river or coastal dikes, the substitution of more temperature-shock resistant plants for sensitive ones, etc. (IPCC, 2007) This may not include “actual” (realized) or “expected” (future) changes in climate.

19 Adaptation (continued) Two types of adaptation: a)Autonomous adaptation ( or reactive adaptation) tends to be what people and systems do as impacts of climate change become apparent b)Anticipatory (or proactive or planned) adaptation are measures taken to reduce potential risks of future climate change.

20 Adaptation Learning Cycle Four broad iterative tasks of an adaptation learning cycle: Assessing climate change vulnerability and impacts Appraising adaptation and selection adaptation options Implementation adaptation options Monitoring and evaluating adaptation action and learning

21 Decision Trees: support the identification of critical tasks and methods PROVIA (2012)

22 Empirically Based Methods Empirically based methods refer to the gathering of observable data to formulate and test a hypothesis and come to a conclusion. These methods often require the commitment of substantial resources.

23 Theory-driven Approach A theory-driven approach, makes use of existing theoretical insights into the nature and causes of vulnerability to select variables for inclusion, although in practice this necessarily occurs within the limits placed by data availability. This inevitably leads to subjectivity in the choice of indicators, but that can be addressed by ensuring all decisions are grounded in the existing literature and made fully transparent.

24 Characteristics of the Climate Hazards CharacteristicDescriptionValueIndication on critical tasks and appropriate methods TypeAre risks due to current climate vulnerability? Yes/no (i.e. extreme event, slow-onset) If extreme events are considered, decisions may take into account current climate Observed trendHas a past trend been observed? Unknown, not knowable, clear direction, no direction If a past trend has been observed, then it is easier to motivate the affected actors to adapt. If the trend is unknown, collecting data is indicated Future impactsGiven a scenario, can I compute impacts (or outcomes) Yes/noIf future impacts (or outcomes) can be computed, decision-making methods on future outcomes are appropriate. Climate change is the dominant risk factor Climate change is considered to be a major driver only if it is important relative to the other drivers involved Yes/noIf climate change is not the major driver, analysing climate change impacts is not a priority, focus on the other drivers or on factors that are internal to the AS.

25 Characteristics of the Affected Actors CharacteristicDescriptionValueIndication on critical tasks and appropriate methods Heterogeneity Degree difference in socio- economic characteristics between relevant actors High/lowIf degree of difference is high, options which require collective action may be difficult Group size Size of group affected by impacts and taking adaptive action Small/largeIf group size is small, collective action options may be more easily taken Damaged experienced Have actors suffered damage due to extreme weather events Yes/noIf yes, it is necessary to focus on current risks Awareness of current risks Actors perception of risks from current vulnerability and extremes High/lowIf low, risk communication and awareness raising are indicated Potential capacity Actors ability to take adaptation action, includes financial, human, and social capital High/lowIf low, incentives may be considered to influence adaptation Actual capacity Actors actual capacity to act in situation, given possible cognitive and institutional barriers High/lowIf actors have low actual capacity, institutional or behavioural analysis to identify cognitive and institutional barriers to action are indicated

26 Characteristics of the Adaptation Options CharacteristicDescriptionValueIndication on critical tasks and appropriate methods Relative costs Investment costs relative to actors annual income and capital stock. High/lowIf the costs are high, the ability to experiment and learn (through ex-post evaluation) may be reduced Investment horizon Time interval over which outcomes attributes can be attributed to an option and must be considered. Short/longIf the horizon is long, then it is desirable to assess impacts, or include impacts in decision -making Flexibility Degree to which option can be adjusted, or changed. Institutional options tend to be more flexible than physical options Yes/noIf option can be adjusted easily, then adaptive management may be appropriate Conflict Degree to which individual preferences and social welfare are in conflict High/lowIf conflict is high, then institutional analysis may be necessary Complexity Number and degree of interdependency of variables that determine outcomes High/lowIf the complexity is high, it is necessary to conduct detailed case studies and/or build models in order to understand and predict action-outcome linkages. If low, decisions can be made without expert knowledge

27 The looped circles indicate that once a task has been identified and a method applied, the process should be repeated, based on the new adaptation situation to identify the next task. Identifying Tasks Based on Adaptation PROVIA (2012)

28 Analyse future impacts or current state? Impact analysis Capacity analysis Private sector National prioritizing Resource constraints Time constraints Lack of data Large uncertainties Participatory setting The focus on impact analysis or capacity analysis, is often not determined by clear-cut criteria: Impact analysis may be more appropriate to identify priorities for national or regional adaptation interventions or deeper analysis Capacity analysis may be more appropriate to identifying and designing actions at local levels. Impact and Capacity Analysis PROVIA (2012)

29 High-order Decision Tree for Capacity Analysis Capacity of whom? Organizational self- assessment Public Purpose of the analysis? Adaptive capacity indication Quick high-level screening in order to prioritize further analysis Private Public capacity analysis Identification of public adaptation options PROVIA (2012)

30 Analysing Impacts Analysing observed or expected impacts of climate change (with and without adaptation). Tasks and methods associated with this sub-task will be called impact-analytical approaches. Analysing the capacity to prevent, moderate or adapt to these impacts requires a diverse range of approaches including indicators, behaviour-analytical and institution-analytical approaches

31 Impact-analytical Methods

32 Decision Tree to Identify Impact Analytical Tasks and Methods PROVIA (2012)

33 Impact-analytical Methods Method Type Subtype Impact Projection Potential Impact Projection (PIP) Residual Impact Projection (RIP) TaskProject future impacts of climate change Characteristics of Adaptation Strategies (AS) Interaction between the drivers and the study unit can be formally represented as a computational model. Given a scenario, impacts can be computed Theoretical assumptions People affected do not adapt. People affected adapt Adaptation can be formally represented by a computational model Steps taken 1. Selection of climate and socio-economic scenarios 2. Computation of the potential impacts of those scenarios 3. Evaluation of impacts using impact indicators 1. Selection of climate and socio-economic scenarios 2. Selection of adaptation options and strategies 3. Computation of the impacts of the scenarios and the adaptation strategies 4. Evaluation of impacts using impact indicators Results achieved A list of propositions that map each scenario to an impact. Each proposition is interpreted in the following way: “When the world evolves according to scenario e and people don't adapt, the impact on will be i” A list of propositions that map each scenario to a residual impact. Each proposition is interpreted: "When the world evolves according to scenario e and one adapts according to strategy a, the impact on the vulnerable system will be i"

34 Impact-analytical Methods (continued) Method Type Subtype Impact Projection Potential Impact Projection (PIP) Residual Impact Projection (RIP) Example Cases Dasgupta et al. (2007) address the question of what are the impacts of sea-level rise on developing countries. Impacts are projected for sea-level rise scenarios of 1 to 5 meter by overlaying data on land, population, agriculture, urban extent, wetlands and gross domestic product (GDP) with the inundation zones of the sea-level rise scenarios. They found that tens of millions of people will be displaced and economic damages will be severe but limited to a couple of countries Hinkel et al. (2010) address the question of what will be both the potential and the residual impacts of sea-level rise on coastal countries of the EU27. The authors use the DIVA model to project the impacts of various sea-level rise and socio-economic scenarios on the countries first without any adaptation (potential impacts) and then with an adaptation strategy (residual impacts) that raises dikes to protect against coastal flooding and nourishes beach to protect against coastal erosion. It is found that, while the potential impacts are substantial, adaptation reduces these impacts significantly by one or two orders of magnitude Issues involved Rarely understood that potential impacts will almost certainly not occur because adaptation will take place. For example, people living in the coastal zone are likely to move away before experiencing permanent flooding How to model adaptation? Model of adaptation (e.g. dumb, typical, smart and clairvoyant farmer) used has a significant indication on the results produced

35 Decision-tree for choosing tasks relevant to analysing capacity from a public perspective in order to identify options Decision-tree: Choosing Tasks Relevant to Analysing Capacity PROVIA (2012)

36 Entry Point: Public Adaptation Problem in Which the Analyst Must Consider the Critical Tasks for Influence the Adaptation of Other (Private) Actors Inter- dependenc e Potential capacity of private actors Actual capacity of private actors ExampleIndication on the next task to carry out NoHighLow Public actor wanting to influence elderly people living in isolated areas, often alone threatened by heat waves Behaviour analysis addressing the question: How the capacity of the vulnerable actors to address the risk could be increased. As the actual capacity of the vulnerable actors is low, awareness raising or behaviour and institutional analysis are indicated NoHigh Public actor wanting to influence Tuscan wine farmers threatened by gradual change in mean temperature As the vulnerable actors have capacity to address risks but are not aware of it, the next task would be risk communication or awareness raising (risk communication, training, TV ads) YesLow Farmers using a shared and already scarce groundwater resource that is declining under climate change Institutional analysis addressing the question what kind of institutional arrangements may resolve conflict YesHighLowPublic actor wanting to influence farmers so that they keep migration corridors open in order to allow species to migrate and thus maintain biodiversity Appraising economic incentives. As actors may not have capacity to address the potential loss of biodiversity on their own due to lack of financial incentive to do so, addressing the problem may be a question of designing appropriate economic incentives e.g. through agri-environmental schemes

38 Decision-tree for Choosing the General Approach to Decision-making PROVIA (2012)

39 Empirical Methods Empirically based methods refer to the gathering of observable data to formulate and test a hypothesis and come to a conclusion(s). These methods require often substantial resources to be committed.

40 Methods for Selecting an Option From a Set Cost-benefit analysis (CBA) Cost-effective analysis (CEA) Multi-criteria analysis (MCA ). The criteria for selecting between CBA, CEA and MCA are based on which outcome attributes are of interest to the decision maker. If all attributes can be assigned one common attribute of money, then CBA is appropriate. If only one of the attributes cannot be assigned as a money attribute, then CEA is appropriate. When two or more attributes cannot be assigned a common monetary attribute (and also cannot be expressed in one common attribute) MCA is appropriate.

41 Selecting an Appropriate Decision-making Method Based on Characteristics of the Adaptation Situation Are there risks due to current climate variability? Does the set of options include only short-term/ flexible options? Given a scenario, can I compute the outcome of a given option? Relative costs of options ExampleNext task indicated. Yes n/rHigh Agriculture threatened by drought, options = (several drought-resistant crops) CBA, MCA YesNoYesHigh Forestry threatened by forest fires, options = (emergency response options; planting different tree species ) Coasts threatened by floods. options = (protect, retreat, spread risk) Robust decision-making on current and futures outcomes No Yes Biodiversity is threatened as species habitats shifts decrease in area, and may not permit migration due to lack of corridors. options = (maintain habitat corridors, agri-environmental schemes, national park) Robust decision-making on future options

42 Selecting an Appropriate Decision-making Method Based on Characteristics of the Adaptation Situation (continued) Are there risks due to current climate variability? Does the set of options include only short-term/ flexible options? Given a scenario, can I compute the outcome of a given option? Relative costs of options ExampleNext task indicated. No YesHigh Agriculture threatened by drought, Options = (improving irrigation) Ski lift operators threatened by decreasing snow fall. options = (summer tourism, artificial snow-making, give up) Robust decision-making on current and future outcomes Non/rNoNot known Extreme event risk in central Europe As the direction of the trend in risks is not clear, adaptation action is not required

43 PART 2: Vulnerability and Adaptation Frameworks

44 Overview of Frameworks Description of some vulnerability and adaptation (V&A) frameworks One size does not fit all Select a framework or method that best suits: a)The questions being asked b)Who is asking them c)What kind of answers are needed d)What resources, time data and technical support are available e)Have you used one before.

45 “Start with the end in mind”

46 Two Types of Frameworks Impacts: a)Also known as “first generation” or “top down” Adaptation: a)Also known as “second generation” or “bottom up”.

47 The Top-down Approach versus the Bottom-up Approach

48 Impacts Frameworks These frameworks are driven by the need to understand long-term consequences: a)Tend to look out many decades (to 2100 or beyond) b)Tend to be scenario driven

49 Adaptation Frameworks These frameworks are driven by the following: The need to supply useful information to stakeholders: a)They tend to address near-term concerns b)Often address climate variability and change c)Emphasis is on the socio-economic context Stakeholder identification of issues and involvement in process: a)Bring in analysis as necessary and appropriate b)Can use consultative/consensus-building techniques.

70 Risk-Based Frameworks Risk is defined as: The chance of something happening that will have an impact on objectives So risk is positive and negative And….must be a risk to something (a management objective).

71 Risk-Based Frameworks (Source: AdaptiveFutures, 2011)

72 Risk-Based Frameworks (Source: Australian Government, 2006)

73 Four NGO Local and Community Frameworks

74 Selecting a Framework We are not recommending use of a particular framework: a)Different frameworks are appropriate for different needs What is needed in the long run is the integration of climate change predictions and adaptation with a baseline of vulnerability.

75 Selecting a Framework: Guiding Questions What is of concern – food production, water supply, health, ecosystem loss? a)(Concerns may be expressed not in climate terms (e.g. extreme temperature) but in consequences of climate impacts for people (e.g. drought, flood, malnutrition) Are there places (areas) that may be particularly vulnerable that may need specific risk assessments? Who may be affected – where are they and what groups in society? How far into the future is the concern? For what purpose is the assessment to be used – raising awareness (education), policymaking? What kind of output is needed?

76 Application of Frameworks Projects often take longer and cost more than originally thought (or proposed) Be careful about complex frameworks You may only get through the first few steps before running out of time or funds Think about how a sectoral project will be run to promote consistency Think about integrating sectoral assessments at the end.

77 Key Factors in Determining How to Conduct Your Study You should not begin with the methods or models you have in hand, but with the important questions Select methods and models that best help you answer the questions.
