Despite considerable uncertainties regarding the exact contribution of anthropogenic climate change to disaster risk, rising losses from extreme events have highlighted the need to comprehensively address climate-related risk. This requires linking climate adaptation to disaster risk management (DRM), leading to what has been broadly referred to as climate risk management (CRM). While this concept has received attention in debate, important gaps remain in terms of operationalizing it with applicable methods and tools for specific risks and decision-contexts. By developing and applying a methodological approach to CRM in the decision context of sovereign risk (flooding) in Austria we test the usefulness of CRM, and based on these insights, inform applications in other decision contexts. Our methodological approach builds on multiple lines of evidence and methods. These comprise of a broad stakeholder engagement process, empirical analysis of public budgets, and risk-focused economic modelling. We find that a CRM framework is able to inform instrumental as well as reflexive and participatory debate in practice. Due to the complex interaction of social-ecological systems with climate risks, and taking into account the likelihood of future contingent climate-related fiscal liabilities increasing substantially as a result of socioeconomic developments and climate change, we identify the need for advanced learning processes and iterative updates of CRM management plans. We suggest that strategies comprising a portfolio of policy measures to reduce and manage climate-related risks are particularly effective if they tailor individual instruments to the specific requirements of different risk layers.

The Warsaw Loss and Damage Mechanism holds high appeal for complementing actions on climate change adaptation and mitigation, and for delivering needed support for tackling intolerable climate related-risks that will neither be addressed by mitigation nor by adaptation. Yet, negotiations under the UNFCCC are caught between demands for climate justice, understood as compensation, for increases in extreme and slow-onset event risk, and the reluctance of other parties to consider Loss and Damage outside of an adaptation framework. Working towards a jointly acceptable positionwe suggest an actionableway forward for the deliberations may be based on aligning comprehensive climate risk analytics with distributive and compensatory justice considerations. Our proposed framework involves in a shortmedium term, needs-based perspective support for climate risk management beyond countries ability to absorb risk. In a medium-longer term, liability-based perspective we particularly suggest to consider liabilities attributable to anthropogenic climate change and associated impacts. We develop the framework based on principles of need and liability, and identify the policy space for Loss and Damage as composed of curative and transformativemeasures. Transformativemeasures, such as managed retreat, have already received attention in discussions on comprehensive climate risk management. Curative action is less clearly defined, and more contested. Among others, support for a climate displacement facility could qualify here. For both sets of measures, risk financing (such as "climate insurance") emerges as an entry point for further policy action, as it holds potential for both risk management as well as compensation functions. To quantify the Loss and Damage space for specific countries, we suggest as one option to build on a risk layering approach that segments risk and risk interventions according to risk tolerance. An application to fiscal risks in Bangladesh and at the global scale provides an estimate of countries' financial support needs for dealing with intolerable layers of flood risk.With many aspects of Loss and Damage being of immaterial nature, we finally suggest that our broad risk and justice approach in principle can also see application to issues such as migration and preservation of cultural heritage.

The debate on "Loss and Damage" (L&D) has gained traction over the last few years. Supported by growing scientific evidence of anthropogenic climate change amplifying frequency, intensity and duration of climate-related hazards as well as observed increases in climate-related impacts and risks in many regions, the "Warsaw International Mechanism for Loss and Damage" was established in 2013 and further supported through the Paris Agreement in 2015. Despite advances, the debate currently is broad, diffuse and somewhat confusing, while concepts, meth ods and tools, as well as directions for policy remain vague and often contested. This book, a joint effort of the Loss and Damage Network - a partnership effort by scientists and practitioners from around the globe - provides evidence-based insight into the L&D discourse by highlighting state-of-the-art research conducted across multiple disciplines, by showcasing applications in practice and by providing insight into policy contexts and salient policy options. This introductory chapter summarises key findings of the twenty-two book chapters in terms of five propositions. These propositions, each building on relevant findings linked to forward-looking sugges tions for research, policy and practice, reflect the architecture of the book, whose sections proceed from setting the stage to critical issues, followed by a section on methods and tools, to chapters that provide geographic perspectives, and finally to a section that identifies potential policy options. The propositions comprise (1) Risk management can be an effective entry point for aligning perspectives and debates, if framed comprehensively, coupled with climate justice considerations and linked to established risk management and adaptation practice; (2) Attribution science is advancing rapidly and fundamental to informing actions to minimise, avert, and address losses and damages; (3) Climate change research, in addition to identifying physical/hard limits to adaptation, needs to more systematically examine soft limits to adaptation, for which we find some evidence across several geographies globally; (4) Climate risk insurance mechanisms can serve the prevention and cure aspects emphasised in the L&D debate but solidarity and accountability aspects need further attention, for which we find tentative indication in applications around the world; (5) Policy deliberations may need to overcome the perception that L&D constitutes a win-lose negotiation "game" by developing a more inclusive narrative that highlights collective ambition for tackling risks, mutual benefits and the role of Transformation.

由聯合國環境署和世界氣象組織在1988年成立之「跨政府氣候變遷小組」（Intergovernmental Panel on Climate Change，IPCC）公佈之「2007氣候變遷報告」中指出，近五十年來觀察到之暖化現象極可能係由人類活動所導致。報告中引用最新科學研究資料指出，氣候變暖之趨勢正在加快，明顯可觀察到之現象包括：極端氣溫天氣之增多、全球海平面上升、一些地區乾旱加重、冰川融化、冰蓋萎縮等等。這種快速氣候變遷所帶來的衝擊，對於地球生態而言，是一種嚴峻的考驗。 台灣地處亞熱帶，且因所在地理位置，深受海洋與大氣交互作用之影響，再加上地形狹窄、河道短促等自然環境因素影響，使台灣成為颱風頻繁的地方；除了颱風本身外，颱風之累積雨量與單位時間內之降雨量又屢創新高，甚至出現了罕見之冬颱；其所附帶的豪雨，造成重大損失。 我國文獻對於颱風洪水險是否作為政策性保險之討論較少，故本論文希望能就颱風洪水險是否適合做為政策性保險加以探討。首先，從氣候風險管理之角度著手，收集現行國內外氣候變遷現況之資料，提出氣候巨災風險管理之方法。再介紹外國與我國現行之颱風洪水保險制度，並論述颱風洪水保險制度之設計原則與方式。接下來，介紹政策性保險，並針對颱風洪水保險可否為政策性保險為違憲審查。最後，針對颱風洪水險作為政策性保險之可行性進行研討，提出可行之方案，並與我國現行已存在之政策性保險相比較，討論我國現行颱風洪水保險之優缺點，再為制度之抉擇。之後，再討論相關問題，以作為我國以後是否發展強制或半強制颱風洪水險之參考。

Climate resilience is increasingly an attribute of competitive global cities. Cities that are most responsive to change will continue to prosper. To achieve this, governance structures and decision-making approaches that promote flexible and/or robust adaptation action are required. This thesis introduces a framework for urban adaptation planning that links medium-term risk management with the development and appraisal of long-term adaptation pathways. A long-term plan informed by the appraisal of a range of plausible pathways provides the opportunity to retain the flexibility to respond to future uncertainties, whilst also demonstrating how a city could manage future climate risk. This provides stakeholders with confidence that long-term risk is adequately considered, even if there is not a need to act immediately. To demonstrate how adaptation pathways can support adaptation decision-making in an urban system, the approach and methods developed as part of this thesis are applied in London. Adaptation pathways in response to water scarcity, surface water flood and heat risk were developed, and their appraisal presented as pathways diagrams. These diagrams provide a visual representation of the sequencing of decision points and plausible adaptation actions that may be implemented in the future. Pathways diagrams present climate risk and adaptation information for decision-makers in a salient and actionable manner. The pathways responding to individual risks in London are then brought together to demonstrate how an integrated assessment framework may be used to appraise city-scale adaptation pathways that respond to multiple climate risks. The growing emphasis within adaptation planning on approaches that can react flexibly to change increases the need to better understand the dynamics of climate risk and embed learning about the effectiveness of adaptation actions. To complement the pathways and adaptation decision-making research presented in this thesis, a framework that links adaptation monitoring and evaluation (M&E), risk assessment and decision-making is presented and explored to highlight the potential benefits of, and mechanisms for, adaptation M&E to inform and strengthen iterative risk-based adaptation planning. Demonstrated for the Thames Estuary, where concepts of adaptation planning have been pioneered but the opportunities of linking to monitoring and evaluation have not been extensively explored, we show how the framework can highlight actions and factors that are contributing to improving adaptation outcomes and those that require strengthening. This thesis contributes to the literature on urban climate change adaptation planning under conditions of uncertainty. This thesis also contributes to the evidence base needed to justify long-term planning and realise the benefits of climate risk reduction through the implementation of flexible, long-term integrated urban adaptation plans.

Bakgrund och problem: Klimatförändringar har ökat allt mer med åren och är idag ett hot mot både individens hälsa och säkerhet. Tidigare forskning har studerat hur olika branscher, som bland annat material- och industribranschen, redovisar kring klimatrelaterade risker. Däremot har dessa studier inte fokuserat på hur endast en bransch redovisar kring klimatrelaterade risker. Dessutom finns det få studier som har fokuserat på hur redovisningen av klimatrelaterade risker påverkats av tvingande hållbarhetsrapportering.  Syftet: Syftet med denna studie är att undersöka hur tre av Sveriges storbanker redovisar kring risker som är till följd av klimatförändringar i års- och hållbarhetsrapporter och hur det har utvecklats för de tre årtalen 2016, 2019 och 2022. Studien bidrar till att få en ökad förståelse på hur tvingande hållbarhetsrapportering och införandet av ramverket Task Force on Climate - related Financial Disclosure påverkar redovisningen av klimatrelaterade risker.  Frågeställning: Hur redovisar banker kring de risker som är till följd av klimatförändringar i års- och hållbarhetsrapporter och har tvingande hållbarhetsrapportering påverkat redovisningen? Hur påverkas innehållet av års- och hållbarhetsrapporten vid införandet av TCFD? Metod: Inom denna studie har en metodkombination, kvalitativ och kvantitativ forskningsstrategi, tillämpats i form av en komparativ forskningsdesign. En innehållsanalys har genomförts. En kodningsmanual och ett kodningsschema har utformats med hjälp av kvalitativa frågor och kvantitativ data.  Resultat och slutsats: Studiens resultat kan visa på att det har skett en utveckling kring bankernas redovisning av klimatrisker för år 2016, 2019 och 2022.  Studien påvisar att bankerna har utvecklats från ett allmänt förhållningssätt till en mer specifik redovisning av klimatrisker, vilket tyder på en positiv påverkan från införandet av tvingande hållbarhetsrapportering. Vidare påvisar studien att införandet av ramverket TCFD har bidragit till en mer omfattande och detaljerad redovisning av klimatrisker, vilket i sin tur även tyder på en positiv påverkan. / Background and Problem: Climate changes have progressively intensified over the years and are presently a menace to both individual well-being and security. Prior research has explored how various sectors, including materials and industrial sectors, disclose climate-related risks. However, these inquiries have not centered on the singular disclosure of climate-related risks within a single sector. Furthermore, a limited number of studies have concentrated on how the reporting of climate-related risks has been influenced by mandatory sustainability reporting. Objective: The purpose of this study is to examine how three of Sweden's major banks disclose risks resulting from climate change in their annual and sustainability reports, and how it has evolved for the three years 2016, 2019, and 2022. The study contributes to enhancing the understanding of how mandatory sustainability reporting and the implementation of the Task Force on Climate-related Financial Disclosure framework influence the disclosure of climate-related risks. Research Question: How do banks disclose the risks resulting from climate change in annual and sustainability reports, and how has mandatory sustainability reporting affected the disclosure? How is the content of the annual and sustainability reports influenced by the implementation of TCFD (Task Force on Climate-related Financial Disclosure)? Method: This study employs a mixed-methods research strategy, combining qualitative and quantitative approaches, in the form of a comparative research design. To examine the banks' annual and sustainability reports for the years 2016, 2019, and 2022, a content analysis has been conducted. A coding manual and coding scheme have been developed using qualitative questions and quantitative data. Results and Conclusion: The results of the study can indicate that there has been a progression in the disclosure of climate risks by banks for the years 2016, 2019, and 2022. The study demonstrates that banks have evolved from a general approach to a more specific disclosure of climate risks, implying a favorable impact stemming from the implementation of mandatory sustainability reporting. Furthermore, the study highlights that the adoption of the TCFD framework has contributed to a more comprehensive and intricate disclosure of climate risks, which, in turn, also suggests a positive influence.

Die Anzahl der unterernährten Menschen in der Welt steigt seit 2017 wieder an. Der Klimawandel wird den Druck auf die Landwirtschaft und die Ernährungssicherheit weiter erhöhen, insbesondere für kleinbäuerliche und von Subsistenzwirtschaft geprägte Agrarsysteme in den Tropen. Um die Widerstandsfähigkeit der Ernährungssysteme und die Ernährungssicherheit zu stärken, bedarf es eines Klimarisikomanagements und Klimaanpassung. Dies kann sowohl die Antizipation als auch die Reaktion auf die Auswirkungen der globalen Erwärmung ermöglichen. Eine zentrale Rolle spielen in dieser Hinsicht landwirtschaftliche Modelle. Sie können die Reaktionen von Pflanzen auf Veränderungen in den Klimabedingungen quantifizieren und damit Risiken identifizieren. Diese Dissertation demonstriert anhand dreier in Peru, in Tansania und in Burkina Faso durchgeführten Fallstudien, wie statistische Ertragsmodelle das Klimarisikomanagement und die Anpassung in der tropischen Landwirtschaft unterstützen können. Während die erste Studie zeigt, wie Klimaanpassungsbestrebungen unterstützt werden können, werden in Studie zwei und drei statistische Modelle genutzt, um Ertrags- und Produktionsvorhersagen zu erstellen. Die Ergebnisse können dazu beitragen, Frühwarnsysteme für Ernährungsunsicherheit zu unterstützen. In den drei Veröffentlichungen werden neue Ansätze statistischer Ertragsmodellierung auf verschiedenen räumlichen Ebenen vorgestellt. Ein besonderer Fokus liegt hierbei auf der Weiterentwicklung von bisherigen Ertragsvorhersagen, insbesondere in Bezug auf unabhängige Modellvalidierungen, eine stärkere Berücksichtigung von Wetterextremen und die Übertragbarkeit der Modelle auf andere Regionen. / The number of undernourished people in the world has been increasing since 2017. Climate change will further exacerbate pressure on agriculture and food security, particularly for smallholder and subsistence-based farming systems in the tropics. Anticipating and responding to global warming through climate risk management is needed to increase the resilience of food systems and food security. Crop models play an indispensable role in this regard. They allow quantifying crop responses to changes in climatic conditions and thus identify risks. This dissertation demonstrates how statistical crop modelling can inform climate risk management and adaptation in tropical agriculture in the case studies of Peru, Tanzania and Burkina Faso. While the first study shows how statistical crop models can support climate adaptation, studies two and three provide yield and production forecasts. The results can contribute to supporting early warning systems on food insecurity. The three publications present novel approaches of statistical yield modelling at different spatial scales. A particular focus is on further developing existing yield forecasts, especially with regard to independent rigorous model validations, improved consideration of weather extremes, and the transferability of the models to other regions.
