4 Theoretical Framework for CBA
4.2 Key Concepts
4.3.1 Development and Adaptation Continuum
The rise of adaptation as a development issue (for example, a focus on equity and rights) has evolved together with the recognition of three points that have been mentioned earlier. In short that: (1) the negative impacts of climate change are not caused by physical and climatic factors alone, but are enhanced or alleviated by socio-economic, cultural, political and other factors as well (Bodley, 2001 in Schipper, 2004); (2) the poor in low- and middle-income nations are expected to be disproportionately at risk from climate change impacts; and (3) poverty is expected to be exacerbated as climate change impacts undermine development efforts (McGray, Hammil, & Bradley, 2007). As a result it is acknowledged that there is a need for adaptation to not only focus on physical infrastructure and specific climate change
responses, but to also incorporate and address the multiple and cross-sectoral factors of vulnerability.
This has led to a diversity of adaptation approaches that range from ‘pure development’ to ‘explicit climate change measures’ (Tanner & Mitchell, 2008).
McGray and others (2007) argue that it is impossible to represent these in one model and thus they frame the interrelationship between development and adaptation in a Development and Adaptation Continuum (see Figure 10). The continuum
“categorizes adaptation efforts according to whether vulnerability or impacts are emphasized in the approach taken” (McGray et al., 2007, p. 23). It places adaptive responses to specific climate change impacts on one end (the right) meanwhile placing responses that reduce vulnerability and deal with a range of impacts by building adaptive capacity on the other end (the left). This illustrates how on one extreme adaptation is seen distinctively from ‘normal development’ and on the other extreme adaptation is understood to be synonymous to development as it addresses the underlying vulnerability issues, which make people at risk to climate change impacts.

The continuum can be divided into four zones of adaptation (from left to right): (1) addressing the drivers of vulnerability; (2) building response capacity; (3) climate risk management; and (4) confronting climate change. Activities under the first zone are primarily to strengthen and support human development therefore the foci of activities are poverty reduction and other causes of vulnerability (that may be climate related or not). “Very little attention to specific climate change is paid during these interventions” and any benefits for adaptive capacity are knock-on effects (McGray et al., 2007, p. 2). However because climate change effects are not purposefully taken into account, some interventions “run the risk of maladaptation”, “may fall outside the mandate of climate change policies” – making it difficult to access funding for this type of adaptation, and can also “appear massive in scope” (Ibid., pp. 17, 18 and 19). The second zone of adaptation deals with high levels of uncertainty in the realm of climate change impacts and thus focuses on “building robust systems for problem solving. These capacity-building efforts lay the foundation for more targeted actions and frequently entail institution-building and technological approaches familiar to the development community... These activities may have many benefits other than adaptation to climate change, but they typically occur in sectors more directly relevant to climate change” (McGray et al., 2007, p. 20). In this approach, climate change awareness means that it can be prioritized over other areas, but still interventions may be short-term and include resilience-building (Ibid.). The third zone of adaptation focuses purposefully on hazards and impacts and derives guidance from the concept of climate risk management (CRM) and may be seen as ‘climate-proofing’. McGray and others state that CRM “encourages managing current climate-related risks as a basis for managing more complex, longer-term risks associated with climate change” and therefore aims to incorporate climate information into development and planning decisions to reduce negative impacts (2007, p. 21). CRM also provides for the reality that future climate change impacts may not be easily distinguished from current climate variability. The fourth and final
zone of adaptation focuses on creating exclusive response mechanisms to specific impacts that are distinctly outside the realm of current and historic climate variability, for example sea-level rise. Few of these interventions have been seen to date because they are costly, highly technical and depend upon a relatively high level of certainty of climate change impacts. A main shortfall of this is that it neglects addressing “the real causes of vulnerability” to climate change (McGray et al., 2007, p. 17).
In terms of the practice and theory of CBA they may be perceived through the paradigm of ‘adaptation as development’, which acknowledges that “overall development is an effective contribution to withstanding future climate change”
(Ayers & Forsyth, 2009, p. 25). This works two ways so that “effective development planning process[es] … take climate change into account and … facilitate adaptation to the effects of climate change” meanwhile “adaptation will … include “regular”
development interventions to ensure the sustainability and overall success of its results” (McGray et al., 2007, p. 5). As such CBA may incorporate activities that span the three left-most responses in the continuum (represented by the grey shading in Figure 10) and most firmly sits under ‘Building response capacity’. Therefore, as this research seeks to learn about CBA in the context of settlement development planning, it will investigate three of McGray and others’ four possible forms of adaptation: first, ‘addressing the drivers of vulnerability’ (for example by providing safe and permanent housing, basic infrastructure and service provision, and secure land tenure);; second, ‘build response capacity’ (such as building robust institutional capacity and planning processes to support urban climate change adaptation); and third, ‘climate risk management’ (such as how NGO’s are purposefully incorporating climate change adaptation into settlement development planning for the urban poor).
It is vital to see CBA through the ‘adaptation as development’ paradigm;; specifically, to see where it fits along the Development and Adaptation continuum and to recognize that there is a spectrum of adaptation responses that span from addressing
specific climate change impacts to addressing social vulnerability issues that also comes under development initiatives. Without this, one risks judging all adaptation responses with the same criteria, and expecting all adaptation to address specific climate change impacts and to be an independent activity from development.
