Introduction

International lawcanplayan important role in promoting national, regional and internationalactions to tackle the human impacts of climate change and disasters. Of note, 2015 saw the adoption of three interconnected normative frameworks: the Sendai Framework for Disaster Risk Reduction 2015–2030, the Paris Agreement under the UN Framework Convention on Climate Change (UNFCCC), and the UN’s 2030Agenda for Sustainable Development and the Sustainable Development Goals (SDGs). This was no small achievement, as the different evolutionary pathways and siloed nature of these topics had meant that they had remained ‘stubbornly separate’ up until that point (Melamed et al., 2012).Footnote 1 The UN’s 2030 Agenda was constructed as the centrepiece of global efforts to eradicate poverty and its stated aim is to provide an all-encompassing approach to sustainable development in all its dimensions (economic, social and environmental). In addition to reiterating the importance of full respect for international law and human rights, the Agenda reaffirms the interrelated nature of international commitments made by states and the challenges that they face, while simultaneously highlighting the need for ‘integrated solutions’. (UNGA, 2015, paras. 10–13).

One may therefore be tempted to view this body of international norms, rules and standards as a comprehensive and unified system. To an extent, this is correct, with states and the various components of the United Nations systemFootnote 2 proposing, debating, interpreting and implementing a multitude of international instruments and institutional arrangements. However, conversely, the range of actors and thematic areas of international regulation has grown exponentially since 1945, leading to a real risk of overlap, gaps and siloed regimes. The increasing complexity and specialisation of different legal regimes have consequently led to concerns regarding a confusing fragmentation of international law (Koskenniemi, 2007; Peters, 2017; Young, 2012). The problem from a legal perspective, as set out in a key report from the International Law Commission, is that:

such specialized law-making and institution-building tends to take place with relative ignorance of legislative and institutional activities in the adjoining fields and of the general principles and practices of international law. The result is conflicts between rules or rule-systems, deviating institutional practices and, possibly, the loss of an overall perspective on the law. (UNGA, 2006, para. 8)

The counterbalance to this fragmentation is set out in Article 31(3)(c) of the Vienna Convention on the Law of Treaties which requires that ‘any relevant rules of international law applicable in the relations between the parties’ are considered during the interpretation of a specific treaty. This ‘systemic integration’ of competing international legal obligations was introduced so as to avoid contradictions between different international instruments (McLachlan, 2005). While this integrative imperative applies to conflicting bindinginternational norms, to resolve contradictory articles in two different international treaties, however, questions remain as to the role played by internationally adopted non-binding norms or instruments (so-called ‘soft law’) and whether one can even talk of systemic integration between binding and non-binding texts. For example, while the UNFCCC and Paris Agreement are bindinginternational legal instruments,Footnote 3 both the Sendai Framework and the SDGs were adopted as authoritative policyframeworks rather than enforceable legal obligations. So, as we shall see in Sect. Relationship between International Law and Soft Law below, while the close connection in subject matter and required actions between these three instruments is well recognised and highlighted by their partially overlapping goals (Melamed et al., 2012; Natoli, 2019), the legal relationship between them is far from clear. The challenge becomes even more acute when one reviews the language used in these different documents. There are references to the need for ‘integrated approaches,’ ‘policy coherence,’ ‘policy integration’ and ‘stronger interlinkages,’ yet these phrases appear to be used interchangeably and nowhere are they properly defined (Natoli, 2020b).

Despite this legal indeterminacy, the normative impact that social structures and institutions have on hazard prevention, preparation and response is undeniable (de Leon & Pittock, 2017).Footnote 4 Therefore, our analysis draws on insights from disaster risk management theory and practice. As argued by Albis, Lauta and Raju: ‘Disasters … have social roots. Thus the management of disasters today is dependent on the organisation of society, and hence on our ability to integrate relevant knowledge into the institutional arrangements and policies that underpin our ability to address disaster risk’ (Albis et al., 2020). Multi-level understanding and sharing of knowledge regarding the organisation of legal and policyframeworks can therefore assist in promoting connected thinking and the destruction of disciplinarysilos.Footnote 5

As with other contributions in this book, a key theme running throughout this chapter is the need to understand specific aspects of the relationship between sustainable development, climate change adaptation (CCA) and disaster risk reduction (DRR). From our legal perspective, we hope to provide an overview of the interactions between legal and policyframeworks at the international, regional and national levels, while drawing on empirical observations of the law in practice. The chapter commences with discussion of the legal status of different international instruments, before providing a textual analysis of the language used by states, the UN and other actors in the relevant documents. We then propose an ‘hourglass’ model of the legal relationships between the different frameworks for sustainable development, CCA and DRR based on: (a) systemic coherence at the international level; (b) vertical alignment between the international, regional and national levels; and (c) horizontal integration of international norms at the domestic level.

Methodology

As noted by Christopher McCrudden, a key form of academic legal research is that which focuses on the understanding and internal coherence of legal concepts and legal reasoning. McCrudden highlights that this type of research addresses questions such as ‘how legal concepts fit together, the consistence of the use of concepts in different areas of law, [and] the extent to which general principles can be extracted from legal reasoning that can be used to predict or guide future legal decision-making’ (McCrudden, 2006, p. 632). In researching the coherence of the international normative frameworks addressing sustainable development, CCA and DRR, we have utilised a doctrinal legal analysis, namely a textual analysis of the relevant international instruments.

However, doctrinal legal analysis also requires an understanding of how the law works in practice (Ibid., p. 633), so this chapter also draws on empirical research undertaken in the Pacific Island Countries (PICs) by Dr Natoli through the IRC-MSCA CAROLINE project, ‘Leave No One Behind: Developing Climate-Smart/Disaster Risk Management Laws that Protect People in Vulnerable Situations for a Comprehensive Implementation of the UNAgenda 2030.’Footnote 6

Results and Discussion

Sources and Enforcement of International Law

In domestic legal systems, to understand whether a particular action or omission is required by law, one must first identify whether there is a binding and enforceable rule regulating particular behaviour. For example, in some countries a pedestrian crossing a road on a red light might be committing a criminal or administrative offence, while in others jaywalking may not be prohibited by law and is viewed simply as a risk that the individual takes upon themselves. To find out what the law is, you need to examine the sources of law for that particular country, such as legislation, case law, administrative orders, etc. There are likewise rules setting out the sources of international law. For an international lawyer, the first point of reference is Article 38(1) of the Statute of the International Court of Justice (ICJ), which sets out four sources upon which the ICJ can rely, namely: (a) international conventions; (b) international custom; (c) general principles of law; and (d) judicial decisions and highly qualified publications as a subsidiary means of determination (Wolfrum, 2011). The binding legal status of international conventions, such as the UN Framework Convention on Climate Change, is therefore fairly clear. The challenges arise when one starts examining other internationally authoritative texts, which may or may not have the force of international law. For example, UN General Assembly Resolutions are generally held not to have the force of international law but may influence the behaviour of states, which in turn might come to be recognised as bindinginternational custom.Footnote 7 The most famous example is the Universal Declaration of Human Rights which was initially adopted as a General Assembly Resolution on 8th December 1948 but has subsequently been recognised as binding on all states via customary international law (Hannum, 1996). Other influential texts can include recommendations adopted by international conferences, decisions by international organisations and even guidelines or plans of action developed by non-governmental actors, academics or practitioners (Blutman, 2010, pp. 607–608).

This broad range of authoritative but non-binding sources (at both the domestic and international levels) is often called ‘soft law.’ Debate rages regarding this apparent misnomer – for how can something be ‘law’ if it is not legally enforceable?Footnote 8 While it is outwith the scope of this chapter to engage in depth with this debate, it is nonetheless of direct relevance as two of the three frameworks under consideration, namely the Sendai Framework and the SDGs, fall squarely within the soft law definition (Siders, 2016). Moreover, within the purview of all three frameworks are a series of important non-binding guidance documents, such as the Cancún Adaptation Framework adopted by the UNFCCC Conference of the Parties (CoP16) in 2011.Footnote 9 Both the Sendai Framework and the SDGs were adopted at global diplomatic conferences, following extensive state and non-state actor engagement, and so represent authoritative statements of policy, although not of law.Footnote 10 This in turn raises questions as to their legal relationship with the UNFCCC and Paris Agreement, which contain bindinginternational legal obligations.

Relationship Between International Law and Soft Law

As noted in the Introduction, while therisk of fragmentation of international legal regimes is well recognised, the legal requirement of systemic integration set out in the Vienna Convention on the Law of Treaties only applies to binding international law – in other words, sources of international law corresponding to Article 38(1) of the ICJ Statute, but not soft law sources.Footnote 11 It is therefore difficult to talk of ‘systemic integration’ in the strictly legal sense in regard to the frameworks for CCA, DRR and the SDGs. Yet, it has long been recognised that soft law sources may have normative impact – as far back as 1980, Richard Baxter, while serving as a judge on the ICJ, argued that: ‘I intend to use the term [‘international agreements’] in a much wider sense as comprehending all those norms of conduct which States or persons acting on behalf of States have subscribed to, without regard to their being binding, or enforceable, or subject to an obligation of performance in good faith’ (Baxter, 1980, p. 550). Baxter continues by developing the concept of ‘political treaties’ which are ‘merely joint statements of policy’ (Ibid., p. 551). Using this analogy, states cannot ‘violate’ the Sendai Framework or SDGs, or indeed the Cancún Adaptation Framework, and so there is no legal recourse to enforce states’ compliance.Footnote 12

Yet, if soft law texts cannot be enforced, what is the legal relationship between a binding source of international law such as the Paris Agreement and non-binding texts such as the Sendai Framework and the SDGs? At the simplest level, there is no relationship, since a breach of the Paris Agreement by a state party would need to be adjudicated solely based on the legal obligations set out within the UNFCCCframework.Footnote 13 Conversely, it is not possible for a state to legally violate a non-bindingpolicy document such as the Sendai Framework or the SDGs, so no legal consequences flow from it and it would therefore not trigger that state’s legal obligations in a separate binding text such as the Paris Agreement.

However, when one examines the language used by states in these legal and policyframeworks, it is clear that they have acknowledged the close connections between their substantive content and objectives. The Preamble to the UNFCCC, adopted in 1992, specifically notes that: ‘Responses to climate change should be coordinated with social and economic development in an integrated manner.’Footnote 14 More recently, the final Outcome Statement of the Rio+20 World Summit in 2012 was a key intergovernmental acknowledgement of the need to move away from a fragmented and siloed approach. In particular, at the Rio+20 summit, heads of state called for: ‘disaster risk reduction and the building of resilience to disasters to be addressed with a renewed sense of urgency in the context of sustainable development and poverty eradication and, as appropriate, to be integrated into policies, plans, programmes and budgets at all levels’ (UNGA, 2012, para. 186). Moreover, the Outcome Statement continued to stress:

the importance of stronger interlinkages among disaster risk reduction, recovery and long-termdevelopmentplanning, and call for more coordinated and comprehensive strategies that integrate disaster risk reduction and climate change adaptation considerations into public and private investment, decision-making and the planning of humanitarian and developmentactions, in order to reduce risk, increase resilience and provide a smoother transition between relief, recovery and development. (Ibid., para. 188)

This requirement was solidified three years later when the UN 2030 Agenda reaffirmed ‘the outcomes of all major United Nations conferences and summits which have laid a solid foundation for sustainable development and helped to shape the new Agenda.’ (UNGA, 2015, para. 11). Yet, a semantic examination of the relevant documents shows that key terminology is used in an inconsistent manner. The final section of this chapter will therefore attempt to rationalise the plethora of phrases used to describe the linkages and relationship between these three legal and policyframeworks into a clear structure based on ‘coherence,’ ‘alignment’ and ‘integration’. Considering the diversity of national and regional contexts, this should not be seen as a one-size-fits-all formula but hopefully will provide an overarching mechanism for understanding the (legal) relationships between the three topics.

The ‘Hourglass’ Model: Coherence, Alignment and Integration

Certain words and phrases have a specific legal definition or understanding, both at the domestic level and in international law. So, for example, the ‘principle of integration’ in internationalenvironmental lawFootnote 15 relates to a legal obligation on the part of states to integrate environmental considerations into the planning and implementation of development activities (McIntyre, 2013). Yet, as noted by McIntyre, even within the EU’s advanced regional legal system the precise normative character and substantive content of the principle are far from clear (Ibid., p. 105). In a similar manner, the extensive recourse to the concept of ‘resilience’ in the Sendai Framework, Paris Agreement and 2030 Agenda means that one can view it as a ‘semantic cement’ holding the three frameworks together. However, there has been valid criticism of the differential understandings of the way the concept is employed across the three instruments (Siders, 2016, pp. 114–120). Therefore, for the purposes of this analysis and reflecting the uncertain legal relationships between the different texts under consideration, we will utilise standard dictionary definitions of the relevant words rather than relying upon specific legal definitions.

Due to the multidimensional relationships between the three frameworks at the international, regional and national levels, we will commence with a discussion of systemic coherence at the international level (a), followed by vertical alignment between the international, regional and national/sub-national levels (b), and finally horizontal integration at the domestic level (c). As set out in Fig. 3.1 below, the dynamic nature of these relationships can be visualised in a unified model represented by the classic image of an hourglass.

Systemic Coherence: The Need for Consistency

Starting from the consideration that ‘coherence’ is defined as any ‘logical and consistent’ argument or theory (Soanes & Stevenson, 2006, p. 278), ensuring the effective coexistence of the three global frameworks analysed in this study is facilitated by the extent to which they share the same principles/criteria in their respective normative reasoning and purposes (i.e. logic) and exert a simultaneous regulatory effect without discrepancies and in compatible forms (i.e. consistency).Footnote 16 Both ‘logic’ and ‘consistency’ elements are detectable in the text of the three instruments, albeit in different forms.

The 2030 Agenda /SDGs is the framework where the two elements emerge most vividly. Described as ‘universal’ in nature and based on the idea of a ‘collective journey’, one can consider ‘coherence’ as one of the Agenda’s inherent features, as demonstrated by the recurrent use of this term throughout the document. The Agenda’s overarching purpose of unifying the multifaceted dimensions of sustainability entails humanity living ‘in harmony with nature’ (para. 9), while also being able to cope with the adverse impacts of climate change (para. 14) and related disaster risks (para. 33). This idea is enshrined in the wording of the SDGs, such as Goal 1.5 (‘[B]uild the resilience of the poor and those in vulnerable situations and reduce their exposure and vulnerability to climate-related extreme events’) and Goal 13.1 (‘Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries’). With the clear intention to prevent overlaps or conflicts, the Agenda includes two ‘coherence clauses’ – the first recognising the UNFCCC is the ‘primary international, intergovernmental forum for negotiating the global response to climate change’ (para. 31, plus SDG 13) and the second clarifying that cities and human settlements should develop and implement holistic disaster risk management at all levels ‘in line with the Sendai Framework for Disaster Risk Reduction 2015–2030’ (SDG 11.b).

Likewise, by acknowledging climate change as a key source of disaster risk and a serious impediment to sustainable development, the various intergovernmental negotiations of 2015 were recognised in the Sendai Framework as a ‘unique opportunity to enhance coherence’ across interrelated processes, while ‘respecting’ the role of the UNFCCC ‘within its mandate’.Footnote 17 It is no surprise, therefore, that the Sendai Framework’s guiding principles and priorities openly recognise the need for coherence across the SDG, CCA and DRRagendas in the development and implementation of all relevant policies, plans, practices and mechanisms.Footnote 18

A similar aim can be detected in the Paris Agreement, although through more cautiously diplomatic language. Both the Preamble and certain operative provisions include elements highlighting the intrinsic relationship between climate change, risk reduction and sustainable development – not least the prominent placement of the official acknowledgement of the UN 2030 Agenda and SDG Goal 13 in particular, and the Sendai Framework on the first page of the Agreement. This is followed by Article 2(1) which states that among the Agreement’s objectives is the consolidation of ‘the global response to the threat of climate change, in the context of sustainable development’, including by ‘[i]ncreasing the ability to adapt to the adverse impacts of climate change and foster climate resilience.’ This objective is bolstered by Article 7(1) establishing a ‘global goal on adaptation’ which entails ‘enhancing adaptive capacity, strengthening resilience and reducing vulnerability to climate change, with a view to contributing to sustainable development and ensuring an adequate adaptation response.’ Furthermore, in the context of a state’s nationally determined contributions, Article 6(8) notes ‘the importance of integrated, holistic and balanced non-market approaches’ and continues by stating that such approaches shall aim to ‘… (c) Enable opportunities for coordination across instruments and relevant institutional arrangements.’ These provisions clearly aim to highlight the cross-cutting relationship between a state’s adaptive capacity, climate resilience and sustainable development objectives. However, while the promotion of coherence between the three legal and policyframeworks is a worthwhile goal by itself, it is insufficient. Therefore, we next turn to the processes whereby international normative instruments can influence regional and national approaches, and vice versa.

Vertical Alignment: From International to National/Sub-National (and Back)

Having discussed howthe three frameworks are horizontally interlinked at the international level, we will now consider them through the lens of multilevel governance, namely the vertical relationship between global, regional/sub-regional and national/sub-national decision-making bodies and institutions (Lane & Hesselman, 2017). While the three frameworks under consideration do not explicitly refer to it, the concept of normative ‘alignment’ appears as particularly fit-for-purpose, considering that the verb ‘align’ defines any act of placing or arranging items ‘in a straight line or into correct relative positions’ (Soanes & Stevenson, 2006, p. 33.).

There are a wide variety of differing institutional and legal approaches adopted by regional organisations, and the hourglass model recognises that regional structures and initiatives may act as a central fulcrum to facilitate the two-way flow of knowledge, experience and norms between the national and international levels. For instance, interesting and up-to-date findings on vertical alignment in climate-risk governance can be found by exploring relevant practice within the Pacific Island region which hosts five of the ten most at-risk countries in the world and is where climate change is causing serious consequences at a growing rate (IFRC, 2020). Over the last few years, many Pacific Island Countries (PICs) have been reforming their institutional and normative systems in order to pursue a holistic approach to disaster and climate resilience, and this process has been closely tied to the regional and international advancements from 2015 onwards (Hopkins, 2019). For example, the Government of Fiji has undertaken detailed analysis of how to align their domestic adaptation policies with the Sendai Framework and the SDGs. So, when launching their National Adaptation Plan in 2018, the Fijian Government noted: ‘This NAP has been aligned to support these international agreements as one of many national processes through which these agreements should be achieved’(Republic of Fiji, 2018, p. 37; Natoli, 2020a).

A critical role in this alignment process has been played by regional organisations such as the Pacific Community (SPC), the Secretariat of the Pacific Regional Environment Programme (SPREP) and the Pacific Islands Forum Secretariat (PIFS). These organisations have supported and channelled national efforts to build common positions, promoting the most relevant initiatives and providing the necessary technical expertise. A key outcome of this dynamic is the ‘Framework for Resilient Development in the Pacific (FRDP)’, a high-level strategic document adopted in 2016 to guide different stakeholder groups on how to enhance resilience to climate change and disasters, ‘in ways that contribute to and are embedded in sustainable development’ (SPC et al., 2016).

The FRDP drafting process incorporated the contribution of global bodies such as the UN Development Programme (UNDP) and UN Office for Disaster Risk Reduction (UNDRR). It is not surprising, then, that a clear link with the three instruments of reference is evident throughout the text, where the intention to contribute to and complement their implementation is repeatedly stated (SPC et al., 2016, pp. 3, 5, 10–11). This also provides evidence of PICs’ intention to opt for a coordinated regional implementation of the Post-2015 Agenda on climate-risk governance and feed into global intergovernmental processes with ‘a single voice’.

Of note, the FRDP was the result of an ‘[e]xtensive and inclusive engagement process with stakeholders, from national and communities to regional and international levels’ (SPC et al., 2016, p. 1). In light of this, the vertical ‘positioning’ that inspired the document should not be considered as unidirectional (i.e. only going from the global to the local), as it can also build on the capacity to collect and transmit inputs from communities/civil society to the national, regional and intergovernmental levels. The dynamic nature of this shifting relationship from top-down to bottom-up is represented in the hourglass model proposed here by the simple fact that an hourglass is equally effective whichever way it is turned (see Fig. 3.1).

Horizontal Integration: Mainstreaming into Domestic Law and Policy

Following our discussion of systemic coherence at the international level and vertical alignment between the international, regional/sub-regional and national/sub-national levels, the third component of the hourglass model focuses specifically on national law and policy. Considering that the dictionary definition of ‘integration’ is ‘to combine or be combined to form a whole’ (Soanes & Stevenson, 2006, p. 738), it is perhaps surprising that this phrase is used across so many of the documents cited above. It is clear from the fact that the three relevant frameworks were negotiated in separate parallel mechanisms that states did not intend for them to be combined to form a single instrument. However, the word ‘integration’ is used in a more specific context when discussing the domestic level. For example, SDG Goal 13.2 sets out the need to ‘integrate climate change measures into national policies, strategies and planning.’Footnote 19 Likewise, the Paris Agreement calls on parties to integrate climate adaptation ‘into relevant socioeconomic and environmental policies and actions, where appropriate.’Footnote 20 While the Sendai Framework urges states to ‘mainstream and integrate disaster risk reduction within and across all sectors’ and to address DRR and build resilience to disasters ‘with a renewed sense of urgency in the context of sustainable development and poverty eradication and, as appropriate, to be integrated into policies, plans, programmes, and budget at all levels and considered within relevant frameworks’ (para. 2).

One can therefore deduce that a key objective of drafters in using the word ‘integration’ is not to create a single internationalframework but to encourage states to take a holistic view across all policy areas at the domestic level. The normative reform process currently underway in the Republic of Fiji represents an instructive example of how this perspective can effectively be pursued. A consistent and integrated approach between CCA and DRR can be observed in the relevant policies adopted by the Fijian authorities since 2015, aligning at the same time with regional and global commitments (Natoli, 2020a, pp. 36–45). As clearly set out in the Fiji National Adaptation Plan (NAP): ‘Horizontal integration refers to the mainstreaming of climate change issues into national-level developmentplanning processes so that they are suitably climate-informed’ (Republic of Fiji, 2018, p. 46).

From an institutional point of view, a clear example of integration is given by the new National Climate Change Policy (NCCP), which encompasses a careful articulation of Fiji’s priorities in reducing present and future climate risks through a ‘woven approach’ to resilient development (Republic of Fiji, 2019, p. 8). Interestingly, among its main structural reforms are the creation of a Cabinet Committee on Climate and Disaster Risk (CCCDR) and the re-establishment of the National Climate Change Coordination Committee (NCCCC). The updated mandate of the NCCCC includes a requirement to provide ‘[c]lear guidance for interactions with the National Disaster Management Committee on issues that cross-cut the adaptation and disaster risk reduction objectives to improve the ability to coordinate resources and improve the accuracy of risk reductionreporting and planning’ (Republic of Fiji, 2019, pp. 47, 78).

This domestic integration is also reflected in the current text of the Fijian Climate Change Bill, which was published in late 2019. Drafted in close synergy with the NCCP, the Bill aims to ‘integrate the consideration of climate change projections, articulation of risk reductionresponsibilities and formulation of resilience-building objectives across all sectorplans and strategies.’Footnote 21 Once enacted, the Bill is expected to provide the necessary legal basis for establishing clear responsibilities and obligations, so as to ensure overall consistency across governmental structures and promote the harmonisation and integration of the entire normative system. Of note, the judiciary may be called on to play an important role: as per the current draft Bill, the Fijian High Court will be endowed with the power to set aside and order the remake of any specific legislative act that does not adequately take account of climate change.Footnote 22

Conclusions

Just as sand flows from and into either half of an hourglass, the sharing of knowledge and expertise in the fields of CCA, DRR and sustainable development flows from the local to the national, the regional to the international, and back again. This vertical alignment helps to ensure that there is bidirectional exchange of legal principles and operational experience, as well as monitoring of the actions taken at each level.Footnote 23 As Harold Koh has observed, ‘Twenty-first century international lawmaking has become a swirling interactive process whereby norms get ‘uploaded’ from one country into the international system, and then ‘downloaded’ elsewhere into another country’s laws or even a private actor’s internal rules’ (Koh, 2012). The importance of regional organisations in supporting this interactive process of vertical alignment is evident from the coordinated approach undertaken in the Pacific Region.

However, vertical alignment will be hard to achieve if there is not a coherent body of norms and practice at the international level. Therefore, acknowledging and promoting the shared logic and consistency between the Paris Agreement, Sendai Framework and 2030 Agenda, as well as any inconsistencies, are essential. In other words, while the limited scope of Article 31(1)(c) of the Vienna Convention on the Law of Treaties does not allow us to talk about ‘systemic integration’ of the post-2015 global agenda on climate-riskgovernance from a legal perspective, one can identify ‘systemic coherence’ between the relevant frameworks. Nevertheless, as research from the Pacific region indicates, there is no one-size-fits-all solution to legal and policy integration at the national level. Full integration via the creation of a unitary governmental department or piece of legislation is not necessarily the best option, and each state will need to review their own domestic structures and context.Footnote 24 However, emerging practice is based on the expectation that enhancing integration at the domestic level can reduce duplication and optimise the use of limited resources and the sharing of technical expertise, as well as reflect and support coherence at the international level. As a simple visual representation of these processes, the hourglass model aims to promote understanding of the legal relationship between sustainable development, climate change adaptation and disaster risk reduction, and break down the regulatory silos which have hampered effective cross-cutting dialogue and action in the past.
