Institutions are one of the decisive factors for climate adaptation. Nevertheless, current understanding of the institutions-adaptation-nexus is fragmented across the scientific community; is often theoretically ad-hoc or eclectic and at times contradictory. Moreover, knowledge claims are typically raised either for specific cases or overly generic, whereas a diagnostic method may be most effective for cross-case learning about institutional deficits and success factors in climate adaptation. This study develops an institutional diagnostics approach to climate adaptation by means of a systematic meta-analysis of 52 studies comprising 120 cases from Europe. The results show that maladaptation, adaptation barriers and limits are rooted in institutional deficits that can be depicted as archetypical patterns of institutional attributes. Moreover, the results reveal success factors that enabled actors to prevent, alleviate or overcome specific institutional deficits in climate adaptation. Based on this, a set of diagnostic questions is provided for future in-depth institutional analyses of adaptation. Enhancing our capacities to diagnose causes of maladaptation, adaptation barriers and limits is crucial so as to device governance arrangements that match the features of specific adaptation problems.

Economics has a key role to play for understanding vulnerability and adaptation to climate change. However, economic approaches to climate adaptation are rarely articulated and discussed at a framework level. This article first reviews and critically assesses welfare economics approaches to climate adaptation and, secondly, develops a novel institutional economics approach to climate adaptation. Concepts and tools of welfare economics have contributed to assessments of benefits and costs of adaptation; outlined strategies for adaptation; identified responsibilities of the public sector and described policy instruments for adaptation. However, the neoclassical framing of collective action based on the concept of market failure seems too narrow to do analytical justice to the multitude of governance challenges associated with adaptation. Adaptation economics seems underequipped with analytical tools to study the role of institutions for climate adaptation. Therefore, an institutional economics approach to climate adaptation is developed and illustrated. This approach contributes to integrated economic analyses of climate adaptation in three major ways: First, by broadening the scope of climate adaptation economics; second, by delivering a diagnostic framework of climate adaptation that enables the analyst to explain adaptation processes in a systematic manner, synthesizes findings from a large number of research efforts, places particular research questions, governance problems and results in a broader context, and can guide the design of theoretical and empirical inquiries of climate adaptation; third, by offering research strategies and methods for developing generalisable and valid insights in the face of pronounced heterogeneity and diversity of climate adaptation.

This study examines by which design properties international cooperation can effectively facilitate specific climate adaptation processes at the local level. First, a qualitative meta-analysis of empirical evidence from 23 cases is conducted to identify archetypal patterns of barriers and change factors for climate adaptation in urban squatter settlements and in municipal public sectors in low- and middleincome countries. Second, five modes of international cooperation for climate adaptation are characterized based on UNFCCC documents, process observation and literature review. Third, these results are combined to derive testable propositions about how selected design properties of international cooperation can facilitate local efforts to overcome barriers to urban adaptation in lowand middle-income countries. Findings indicate, first, that a major step to tackle adaptation barriers in squatter settlements is improvements of the status of urban poor in the public sector. Second, national or regional centres of competence are means to foster endogenous dynamics in municipal public sectors. Third, national adaptation policies are arrangements to enable and incentivise municipal adaptation. Fourth, flexible indicators of adaptation benefits are instruments to target international decision making and monitoring systems to local needs. It is finally discussed how these insights and methods can be used to advance the study of international cooperation, barriers and success factors for climate change adaptation.

Adaptation to the consequences of climate change has attracted increasing interest as a necessary complement to greenhouse gas mitigation. Economic approaches to climate adaptation are rarely articulated and discussed explicitly despite many benefits of such a framework-level discourse. Therefore, this article investigates how climate adaptation is framed and approached in economics and attempts to contribute to the development of economic frameworks of climate adaptation. First, the paper identifies and critically reviews four major strands of current adaptation economics: estimation of adaptation benefits and costs, strategies for adaptation, the role of markets and governments, and policy instruments for adaptation. While having their merits, serious methodical difficulties prevail. Moreover, the applied neoclassical framing seems too narrow to capture the plethora of governance challenges and normative criteria revealed in adaptation policy discourses and in the multidisciplinary adaptation literature. The second part of this article outlines an institutional economics approach to climate adaptation that addresses caveats in the current state-of-the-art and offers additional concepts to study climate adaptation. Moreover, promising methods and strategies for adaptation research are presented and future research directions suggested. Finally, the paper assesses the normative foundations of climate adaptation economics and their implications for positive adaptation research.

It has been well established that institutions are decisive for the capacity of society to adapt to climate change. But it is largely subject of debate, how in detail institutions in interaction with the available resources and the characteristics of the actors involved foster or impede the adaptive capacity in multi-level governance systems. Therefore, synthesizing the diverse findings of empirical case studies on this question in a methodologically coherent and integrative manner may provide theoretical foundations for answers on how to organize enhanced adaptive capacity to climate change within and across governance levels.
