Assessing adaptation to climate change and its costs in a carbon-constrained world

This thesis aims at improving the current representation of adaptation in economic frameworks of climate change by a) accounting for the time-dependent evolution of the adaptive capacities of countries and b) quantifying unwelcome feedbacks of the adaptation process. In this context, it is proposed that economic assessments of climate change incorporate adaptation as a cyclic and phase-dependent process while devising their cost methodologies. A phase-dependent process acknowledges the existence of adaptation barriers while a cyclic process accounts for potential unwanted feedbacks of adaptation. By analyzing economic assessments against this framework, it is shown that dependencies between phases of adaptation and phases altogether are often disregarded. Furthermore, potential negative consequences associated with adaptation are rarely considered and adaptation is generally assumed to be unconstrained. The assumption of unconstrained adaptation is only acceptable in the context of high adaptive capacity. This concept was further investigated through a review of vulnerability assessments regarding their operation of the adaptive capacity component. It was found that adaptive capacity is mostly equated to proxies that reflect the knowledge, financial and livelihood capacities of the system under analysis. With this theoretical considerations in mind, a dynamic representation of adaptive capacity was elaborated at a country-level. The Human Development Index (HDI) was used as ...
