1. INTRODUCTION
Despite the ever-increasing number of international treaties, policies, and frameworks adopted to protect the environment, planetary health continues to worsen.Footnote 1 In this context of failing environmental governance, rights of nature (RoN) are increasingly lauded as the paradigm shift needed to transform our legal approach to nature.Footnote 2 The idea has gained momentum with the increased integration of RoN into constitutions, national statutes, and local decrees.Footnote 3 Although diverse, the unifying thread of these initiatives is the recognition that nature, or specific natural ecosystems such as rivers or forests, have rights that are inherent and independent from human interests.Footnote 4 This usually includes the right to exist; persist; maintain and regenerate vital cycles, structure and functions; and a right to restoration and protection.Footnote 5
Despite these developments at the national level and the emergence of a significant body of transnational advocacy, networks, and scholarship,Footnote 6 there has been little progress regarding the incorporation of RoN into international law.Footnote 7 There have been references to the idea that nature might have rights, including in the 1982 United Nations (UN) World Charter for Nature,Footnote 8 the 1992 ‘Forest Declaration’,Footnote 9 and more recently in the Kunming-Montreal Global Biodiversity Framework (GBF) calling for the enhancement of ‘Mother Earth centric actions’.Footnote 10 There are also a number of international civil society declarations pushing for more international legal engagement; these include the Earth Charter in 2000Footnote 11 and the Universal Declaration for the Rights of Mother Earth.Footnote 12 Since 2009, the UN initiative entitled ‘Harmony with Nature’ has documented the rapid growth of RoN initiatives at the national and local levels, and has pushed for recognition of these types of right at the international level.Footnote 13
Nonetheless, RoN are still far from being integrated into international law, with no legally binding treaties or legal precedents specifically proclaiming nature's rights.Footnote 14 Under international law, nature is approached primarily as a legal object rather than a subject of rights,Footnote 15 with most treaties focusing on the rights of states, international organizations, humans, and sometimes corporations and other ‘stakeholders’ – but rarely on nature as rights bearer.Footnote 16 Although there is also a large body of international law that is geared towards the protection of the environment, not only as a resource but also in recognition of its intrinsic value, the value of the environment is usually traced back to benefits for humans.Footnote 17
As analyzed in this article, there are fundamental dichotomies between international law and RoN, many of which can be traced back to the fact that international law tends to approach nature as a ‘resource’ to be owned, exploited or protected for our own benefit.Footnote 18 By questioning whether RoN and international law are compatible, this article reflects on the potential impact that RoN could have on international law and its approach to nature. It argues that despite some serious dichotomies, there are areas of international law that could benefit from further engagement with RoN to support new approaches to nature. The thread of the analysis is that by engaging with RoN, international law could go from a discourse of dominance over nature (Section 2) to a relational approach to nature (Section 3), which could support the development of new legal approaches to our responsibilities of care towards nature (Section 4). This analysis shows that in bridging the gap between these dichotomies between international law and RoN, peoples – especially Indigenous peoples – do play a crucial role in translating the current narrative of dominance into a more collaborative relationship between humans and nature under international law. Based on this more relational approach to nature, the article argues that some key principles of international environmental law – such as the precautionary approach, the principle of no harm, and stewardship – could serve as frameworks to create more synergies with the development of RoN and, as such, contribute to a new international law relationship with nature.
2. DOMINANCE OVER NATURE: SOVEREIGNTY, EXPLOITATION AND CONSERVATION
Under international law, nature is usually approached either as a resource to be owned, exploited, or conserved/protected for human benefit. It is telling that most treaties and international norms do not refer to ‘nature’ but usually adopt the term ‘natural resources’Footnote 19 or ‘the environment’.Footnote 20 The following two subsections examine how the principle of state sovereignty and the dominant focus on development constitute two legal frameworks which are potentially antagonistic to the idea of nature having rights.
2.1. Nature as Sovereignty: States’ Property over Natural Resources
State sovereignty and ownership of nature is the first stumbling block. Control of natural resources located on the territory of a state is one of the key attributes of sovereignty, the conventional premise being that states ‘own’ the natural resources within their jurisdictions.Footnote 21 The principle of state sovereignty over nature has been crystallized under the principle of permanent sovereignty over natural resources, which has been affirmed and proclaimed in countless international decisions and resolutions.Footnote 22 This focus on state sovereignty leaves little space for the idea that nature might have interests that are not aligned with the ultimate ownership of the state in which they are located. Instead, the focus is on states’ rights of ownership and exploitation.Footnote 23 By way of illustration, Article 193 of the UN Convention on the Law of the Sea (UNCLOS)Footnote 24 provides that ‘[s]tates have the sovereign right to exploit their natural resources pursuant to their environmental policies and in accordance with their duty to protect and preserve the marine environment’. Although there are some caveats to the absolute sovereignty of states, they are limited to their duty to protect and preserve the marine environment. The marine environment itself has no rights; it is entirely dependent on the ultimate sovereignty of the state. This is just an example, as under the principle of state permanent sovereignty over natural resources governments are in charge of ensuring the ‘best’ utilization of natural resources.Footnote 25 As analyzed by Bothe, ‘international law assigns the exclusive right to use a resource to the State where the resource is situated’, and decisions about governance of the resource as well as ‘the intertemporal distribution of use is left to the unfettered discretion of that State’.Footnote 26
Under the principle of state sovereignty, the main concern is about defining the nationality of nature. The main legal issue that arises under this framework is to define which states own which part of what ecosystem, a vivid illustration being the rich jurisprudence on disputes between states regarding transboundary rivers.Footnote 27 The focus in such disputes is on which states exercise sovereignty over which part of the river, and what rights and obligations they might have regarding their impact on neighbouring countries. These disputes are never about whether the rivers concerned have any inherent rights outside state interests. On this front, the emerging literature on river rights and transboundary issues offers an interesting first insight into the clash between state sovereignty and the RoN approach, highlighting that indeed the rights of the ecosystems concerned are not yet being addressed.Footnote 28 Instead, the principle of sovereignty creates a framework focusing on the nationality of the rivers, feeding arguments about resource nationalism. Although more research and analysis needs to be undertaken to understand the extent to which RoN might be a legal tool to constrain resource nationalism if nature has inherent and fundamental rights, for cross-border entities it most probably means having rights above and beyond national claims.Footnote 29 The language of sovereignty and national rights over nature are so deeply ingrained in the way in which international law approaches nature, it seems inevitable that if RoN were to be developed more strongly under international law, the dichotomy between the principle of state sovereignty over natural resources and nature's rights might be a first line of battle, at least for ecosystems that transcend national borders.
2.2. Nature as a Resource: Trade, Development and Conservation
The second area of international law to present a serious dichotomy with the idea of nature having inherent rights falls under the broader umbrella of international economic law,Footnote 30 under which nature is approached as a resource to be exploited or developed. The language used in some of the key international instruments on trade law is telling – such as references to ‘using’ natural resources in an ‘optimal’ manner.Footnote 31 For example, the World Trade Organization is founded on the aim of ‘allowing for the optimal use of the world's resources in accordance with the objective of sustainable development, seeking both to protect and preserve the environment and to enhance the means for doing so’.Footnote 32 Notwithstanding the caveat of protecting and preserving the environment, the goal is the ‘optimal’ use of the world's ‘resources’, with nature being seen as a resource to be exploited. This approach is echoed in international investment law, which tends to serve the interests of industries and investors, many of which are involved in the exploitation of natural resources.Footnote 33 When it comes to investment concerning natural resources, international investment law favours the rights of foreign investors to control, own, and exploit natural resources.Footnote 34 One could easily imagine future decisions in investment arbitration cases invalidating laws that recognize RoN or ecosystems, if recognizing such rights would undermine rights of investors under investment law. In the current international law architecture, international investment law can very often trump other interests,Footnote 35 so that investors’ property rights would have priority over RoN.
The principle of sustainable development represents another potential barrier to the idea that nature has inherent rights.Footnote 36 Since the 1992 UN Conference on Environment and Development, the principle of sustainable development has been affirmed in countless international instruments.Footnote 37 As affirmed in the Rio Declaration on Environment and Development: ‘In order to achieve sustainable development, environmental protection shall constitute an integral part of the development process and cannot be considered in isolation from it’.Footnote 38
However, under the surface of what appears to be a supportive approach, there is a fundamental issue when it comes to nature. Sustainable development is about a linear path to ensure economic development and ecological well-being, with nature still seen mainly as a resource to be exploited for the benefit of human development – albeit ‘sustainably’.Footnote 39 In prioritizing human development, the principle perpetuates the idea that nature is there for us – to be used for ‘our development’.Footnote 40 As was made clear in the 1992 Rio Declaration: ‘Human beings are at the centre of concerns for sustainable development’.Footnote 41 Most of the international legal regimes concerning the conservation of nature have adopted a similar approach: nature and its various ecosystems need to be protected to ensure a sustainable future for humans.Footnote 42
To take the argument one step further, what we are seeing in the name of sustainable development is the further commodification of nature as ‘natural capital’ and ‘ecosystem services’ – the logic of sustainable development arguably intensifying (rather than unsettling) the underlying conception of nature as a resource.Footnote 43 Indeed, some critics have characterized sustainable development as an ‘oxymoron’, highlighting instead the emergence of alternative approaches that are more harmonious with nature, such as buen vivir from Latin America, ecological swaraj (or radical ecological democracy) from India, as well as de-growth.Footnote 44
Overall, there are some serious barriers to the idea of nature having rights, notably under the two deeply embedded precepts that nature is either an issue of sovereignty/property or a means to support development. However, as explored below, some areas of international law are starting to challenge both state sovereignty over nature and the idea that nature is primarily a resource to be exploited for human development.
3. RELATIONSHIPS: PEOPLES’ RIGHTS AND NATURE
Although RoN is about affirming that nature has fundamental rights outside human interests, it is also about acknowledging relationships between humans and nature as a source of rights.Footnote 45 Many peoples have spiritual and/or cultural relationships with nature that are not predominantly about human interests but rather could be regarded as relationships of kinship.Footnote 46 The acknowledgement of these cultural relationships with nature is a significant element of the RoN movement.Footnote 47 RoN is part of wider theories of earth jurisprudence, wild law, and ecological jurisprudence, supporting a systemic shift towards a more relational approach to nature.Footnote 48 There is growing scholarship exploring how RoN is supporting a ‘relational turn’ in environmental governance, which, in the words of Macpherson, ‘tends to understand humans as related to and within holistic, living, ecosystems, in the context of complex systems of reciprocal and intertwined rights and responsibilities of use and care’.Footnote 49 As explored in the following discussion, some areas of international law are starting to embrace this ‘relational turn’ by moving away from paradigms of sovereignty, exploitation, and development by instead acknowledging that peoples’ cultural relationships with nature can also be a source of rights. As explored below, this has taken place (i) as part of the development of Indigenous peoples’ international human rights, and (ii) within international biodiversity law, as part of the promotion of the traditional ecological knowledge of local communities.
3.1. International Human Rights Law, Indigenous Peoples and Nature
International human rights law (IHRL) is increasingly engaging with protection of the environment, witnessing what is often labelled as the ‘greening’ of human rights.Footnote 50 This ‘greening’ of IHRL was confirmed with the adoption in 2022 of a UN General Assembly resolution affirming the right to a clean, healthy, and sustainable environment as a human right.Footnote 51 Although the human right to a healthy environment is arguably anthropocentric in that it is about human health,Footnote 52 this has nonetheless opened a connection between international law and the idea of nature having rights. One of the most advanced applications of the right to a healthy environment emerges from the jurisprudence of the Inter-American system of human rights, notably the 2017 advisory opinion of the Inter-American Court of Human Rights (IACtHR), which specifically mentioned RoN:
The Court considers it important to stress that, as an autonomous right, the right to a healthy environment, unlike other rights, protects the components of the environment, such as forests, rivers and seas, as legal interests in themselves, even in the absence of the certainty or evidence of a risk to individuals. This means that it protects nature and the environment, not only because of the benefits they provide to humanity or the effects that their degradation may have on other human rights, such as health, life or personal integrity, but because of their importance to the other living organisms with which we share the planet that also merit protection in their own right.Footnote 53
This statement establishes a clear connection between human rights law and RoN. This approach was later confirmed in the 2020 case concerning the Indigenous Communities Members of the Lhaka Honhat, where the Inter-American Court confirmed this approach linking the right to a healthy environment and RoN.Footnote 54 Relying on its previous advisory opinion on the relationship between human rights and the environment, the Court acknowledged the importance of the protection of nature in itself rather than for its ‘usefulness’ to or ‘effects’ on human beings.Footnote 55 This judgment is part of a wider approach pushed by many Indigenous peoples who have highlighted that their human rights are fundamentally interconnected with nature.Footnote 56 Indigenous worldviews and relationships with nature are now recognized as a significant element of IHRL, notably the rights to self-determination, culture, and spirituality.Footnote 57 UN human rights monitoring bodies have highlighted that the right to ‘take part in cultural life’ includes Indigenous peoples’ cultural values ‘associated with their ancestral lands’.Footnote 58 On many occasions, the IACtHR has highlighted that the close relationship of Indigenous peoples with their ancestral territories ‘must be acknowledged and understood as the fundamental basis for their culture, spiritual life, wholeness, economic survival, and preservation and transmission to future generations’.Footnote 59 As noted by the Court:
The culture of the members of the Indigenous communities directly relates to a specific way of being, seeing, and acting in the world, developed on the basis of their close relationship with their traditional territories and the resources therein, not only because they are their main means of subsistence, but also because they are part of their worldview, their religiosity, and therefore, of their cultural identity.Footnote 60
In a case concerning the Sarayaku communities in Ecuador, the judges noted that ‘[a]ccording to the worldview of the Sarayaku People, their land is associated with a set of meanings: the jungle is alive and nature's elements have spirits (Supay), which are interconnected and whose presence makes places sacred’.Footnote 61 Based on this holistic approach to nature, the Court highlighted the obligations for states to respect the ‘cultural integrity’ of Indigenous peoples, recognizing the inextricability of cultural rights and nature.Footnote 62 As noted in a case concerning the Moiwana community in Suriname, ‘in order for the culture to preserve its very identity and integrity, [Indigenous peoples] … must maintain a fluid and multidimensional relationship with their ancestral lands’.Footnote 63 The Court highlighted that the close relationship between Indigenous peoples and nature must be recognized and understood as the fundamental base of their culture, spiritual life, integrity, economic survival, and cultural preservation.Footnote 64 In the 2015 case of Kaliña and Lokono Peoples, the Court specifically acknowledged the cultural and spiritual relationship of Indigenous peoples with their natural environment, highlighting the communities’ interconnection with the animals, plants, fish, stones, streams and rivers.Footnote 65 The Court recognized that this relationship is based ‘on a profound respect for the environment, which includes both living beings and inanimate objects’.Footnote 66
Human rights courts have also acknowledged that spiritual relationships with nature constitute an expression of the right to freedom of religion. This was affirmed in the 2017 ruling of the African Court on Human and Peoples’ Rights concerning the Ogiek community of Kenya, with the Court highlighting that ‘Indigenous societies in particular, the freedom to worship and to engage in religious ceremonies depends on access to land and the natural environment’.Footnote 67
With these developments, the rights of Indigenous peoples as defined under IHRL acknowledge the cultural, spiritual, and kinship relationships with nature as a source of rights, supporting the emergence of a connection between RoN and international law. Arguably, the approach is still anthropocentric as it is located within human rights law, which by definition is human-centric, but it opens up a legal avenue to recognize relationships with nature that are very different from those explored in Section 2 of this article. The recognition of Indigenous cultural relationships with nature as a source of rights challenges the absolute sovereignty of states over nature, as well as the dominant proprietary discourse surrounding nature. A strong element of the rights of Indigenous peoples under international law has been to challenge the dominant discourse of ownership and property rights over nature in favour of integrating concepts of custodianship and kinship relationships with nature.Footnote 68 It does not mean that the rights of Indigenous peoples always align with RoN,Footnote 69 but it creates a space where Indigenous worldviews and relationships with natural entities can be acknowledged as a source of rights, supporting a ‘relational turn’ in international law.Footnote 70
3.2. Biodiversity, Traditional Ecological Knowledge and ‘Mother Earth’
The recognition of traditional ecological knowledge under international law represents another acknowledgement of peoples’ relationship with nature as a source of rights.Footnote 71 Traditional knowledge is included in several international treaties relating to biodiversity,Footnote 72 desertification,Footnote 73 food and agriculture,Footnote 74 and climate change.Footnote 75 The Convention on Biological Diversity (CBD)Footnote 76 puts some emphasis on the traditional ecological knowledge of Indigenous peoples and other local communities, calling on states to enact national legislation to protect and preserve communities’ traditional knowledge.Footnote 77 The knowledge systems of Indigenous and local communities are understood to be bodies of integrated, holistic, social, and ecological knowledge, practices and beliefs pertaining to the relationship of living beings, with one another and with their environments.Footnote 78 Although the CBD does not specifically mention RoN, it proclaims the ‘intrinsic value of biodiversity’ and, by promoting the traditional knowledge of Indigenous peoples and other local communities, it acknowledges the relationships between humans and nature.Footnote 79 The GBF has gone a step further by affirming that biodiversity is connected to ‘living well in balance and in harmony with Mother Earth’, recognizing the importance of ‘diverse value systems’ when it comes to relationships with nature.Footnote 80 These diverse value systems include ‘for those countries that recognize them, rights of nature and rights of Mother Earth, as being an integral part of [the GBF's] successful implementation’.Footnote 81 More specifically, Target 19 of the GBF calls for ‘[e]nhancing the role of collective actions, including by indigenous peoples and local communities, Mother Earth centric actions and non-market-based approaches including community based natural resource management and civil society cooperation and solidarity aimed at the conservation of biodiversity’.Footnote 82
Although the GBF does not directly affirm that nature has rights, it is probably the closest that international law has come so far in recognizing that different value systems that integrate ‘Mother Earth-centric’ approaches should be part of the fight against the loss of biodiversity.Footnote 83 This development is also linked to the push to recognize biocultural rights,Footnote 84 which have already been at the heart of legal decisions that recognize the rights of natural entities, notably in Colombia.Footnote 85 The fact that traditional ecological knowledge is now well-established under international law opens up a space to recognize that nature has the right to benefit from the traditional ecological stewardship of local communities.
Overall, looking both at the rights of Indigenous peoples and the international legal developments taking place under the banner of biodiversity, there is a body of international law that acknowledges the importance of relationships between peoples and nature, putting forward cultural, spiritual, and traditional ecological practices as a source of rights. In this, international law is aligning with some of the concepts behind RoN, highlighting the importance of acknowledging kinship relationships with nature, and the fact that as humans we are part of a broader earth community.Footnote 86 It does mean that RoN have been affirmed in international law, but recognizing the cultural, ecological, and spiritual relationships with nature creates a space to challenge the prevailing approaches focusing on sovereignty, exploitation, and conservation of nature – hence, starting to unravel some of the dichotomies explored in Section 2 of this article.
4. NATURE'S RIGHT TO A FUTURE: REVISING RESPONSIBILITIES AND STEWARDSHIP
Although RoN is about proclaiming that nature has inherent rights, it is also about affirming that humans have duties of care and responsibilities to respect and enforce these rights.Footnote 87 At the national level, the affirmation of these responsibilities has been key in the development of RoN.Footnote 88 As examined below, duties of care and the representation of nature are concepts that are still marginal in international law, whereas principles of custodianship and representation are key developments in RoN. By focusing on these concepts of responsibilities, duties of care, and representation of nature, this section explores how international law could learn from RoN on these issues.
4.1. Caring and Speaking for Nature: Decolonizing Stewardship?
As noted in a 2013 report of the UN Secretary-General: ‘Nearly all human traditions recognize that the living are sojourners on Earth and temporary stewards of its resources’.Footnote 89 This statement resonates strongly with some of the concepts behind RoN, emphasizing the role of humans as stewards of nature.Footnote 90 The idea of caring for nature – or to act as custodian of and for nature – is at the heart of recognizing nature's rights.Footnote 91 Ultimately, the establishment of specific institutional mechanisms to speak on behalf of nature and act as representatives or the ‘voice’ of nature is essential for embedding RoN into the legal system.Footnote 92 This has led to a rich reflection on how human institutions can best speak on behalf of and represent nature in human governance.Footnote 93
International law is rather underdeveloped when it comes to speaking on behalf of nature. Nature is not represented in international fora and there are no international mechanisms to allow such voice or representation. International law is also underdeveloped when it comes to ‘caring obligations’ towards nature, although environmental stewardship is often put forward as a concept that could support such obligations or duties.Footnote 94 Various forms of stewardship status have been suggested for the Antarctic and polar regions,Footnote 95 for the marine environment,Footnote 96 and the global atmosphereFootnote 97 but, in general, these initiatives remain marginal in international law. Stewardship is also integrated into global governance with, for example, the Forest Stewardship Council and the Marine Stewardship Council setting standards to act with a duty of care for the world's forests and fisheries, but these multi-stakeholder initiatives have demonstrated some serious limitations and very weak implementation.Footnote 98
There has also been international advocacy to integrate the principle of ‘Earth trusteeship’, focusing on a global trusteeship approach to nature, notably to challenge sovereignty.Footnote 99 Earth trusteeship is a principle that is evoked to capture the duty of humankind to act with care towards nature. It is based on the idea that natural resources – such as air, trees, and water – are common and therefore nation-states should perpetually steward them.Footnote 100 Yet, this idea of common trusteeship is rarely fully integrated into international treaties.Footnote 101 In terms of treaty law, the Aarhus Convention is one of the few binding treaties that encourages all actors to accept their custodial stewardship duties in order to benefit present and future generations.Footnote 102 The GBF acknowledges the important roles and contributions of Indigenous peoples and local communities as ‘custodians’ of biodiversity and as partners in its conservation, restoration, and sustainable use.Footnote 103 The 2023 Treaty of the High Seas (known as the BBNJ) concerning the biological diversity in areas beyond national jurisdiction, also expresses the ‘desire … to act as stewards of the ocean in areas beyond national jurisdiction’.Footnote 104 However, these are isolated statements and, in general, concepts of stewardship of nature have not yet been fully embraced or implemented under international law, with no concrete mechanism put in place.
More generally, the concept of stewardship has been criticized for being anthropocentric,Footnote 105 and based on Western and Christian ideals of dominium over nature.Footnote 106 From this perspective, international law can learn from the developments in RoN concerning the establishment of representative institutions and their duties towards nature, notably integrating non-Western approaches to the concepts of custodianship and stewardship based on the leadership of Indigenous peoples.Footnote 107 It could also open the door for reflection on the place of multispecies justice under international law, an idea that is germinating in RoN circles.Footnote 108 In general, nature is not represented in international fora and concepts of stewardship and duties of care are still very marginal. As Payne puts it, ‘[s]tates are unreliable custodians of nature’.Footnote 109 The developments taking place at the national level to implement RoN, via the creation of institutions with a mandate to speak on behalf of nature and with clear obligations of stewardship and duty of care, offer a framework to reinterpret and reinvigorate the principle of stewardship and the idea of nature having a voice in environmental governance.Footnote 110
4.2. Nature's Future: Towards a Non-Human-Centric Approach to Harm?
One of the consequences of proclaiming the RoN is also to recognize that nature has a right to a future not only driven by human sustainable development perspectives, but for the sake of nature itself. For example, the Constitution of Ecuador highlights the duty to ‘apply preventative or restrictive measures on activities that may lead to extinction of species, destruction of ecosystems, or the permanent alteration of natural cycles’.Footnote 111 Although the idea of nature's right to a future is also present in international law, with several key principles of international environmental law being about preventing future harm to nature, these tend to be largely anthropocentric.
One of these is the principle of ‘no harm’, which is at the heart of many international environmental norms.Footnote 112 Originally limited to doing no harm in another state's jurisdiction (transboundary harm), the no-harm principle has evolved towards a more comprehensive precautionary approach.Footnote 113 The precautionary approach requires activities and substances that may be harmful to the environment to be regulated and possibly prohibited even if no conclusive or overwhelming evidence is (yet) available.Footnote 114 However, the approach is largely anthropocentric, typically focusing on the impact that harmful activities might have on human activities.Footnote 115 In general, international law remains very anthropocentric in its approach to harm and reparations, and nature's right to a future.Footnote 116 Integrating nature as a right holder would support the integration of nature as a direct victim.Footnote 117 In examining several decisions adopted by the Court of Justice of the European Union (CJEU) concerning biodiversity offsetting practices, Schoukens has examined what an ecocentric focus on harm could mean in practice. In his analysis he highlighted how some CJEU judges had implicitly relied on the recognition of the intrinsic potential future needs of nature, suggesting the possibility of adopting an ecocentric approach to the precautionary principle.Footnote 118 That line has not yet been crossed in contemporary international jurisprudence, but a RoN interpretation of the precautionary approach would support a more ecocentric understanding of harm. This is where international law can learn from some of the developments regarding ecocentric understanding of harm and reparation emerging under RoN.Footnote 119
Another perspective on nature's rights to a future concerns the rights of future generations, which have been affirmed in various environmental instruments,Footnote 120 declarations and statements on climate change,Footnote 121 and in several court rulings and decisions.Footnote 122 Taken together, these various treaties, declarations, and cases underline an international normative focus on the duty to protect nature for future generations. This is based on an intergenerational duty: integrating a duty for present generations to take care of the planet for the future of ‘the living world’.Footnote 123 Hence, in theory this aligns with the idea that, as humans, we have a duty to act as custodians of the planet. This is a core element of RoN, and is also strongly embedded in some of the RoN cases emerging at the national level with an important focus on intergenerational relationships with nature.Footnote 124 More generally, one of the philosophies behind RoN is also to revisit human perceptions of damage to nature based on a timescale more attuned to natural environment cycles.Footnote 125 In the context of rapidly evolving interpretations and understandings of intergenerational justice, the inclusion of RoN would support a less anthropocentric understanding of what the rights of future generations might mean by including nature in the frame.Footnote 126 It would support an approach to nature's right to a future that is outside the purely protective approach of international law (seen mainly through the lens of a human future and our capacity to have a sustainable future), therefore challenging the meaning of what is ‘sustainable’ not only from a human perspective, but from the perspective of nature.
5. CONCLUSION
International law largely approaches nature as a resource to be owned, traded, exploited, or protected. There are underlying historical, political, and structural reasons – from colonization, economic interests, political and territorial disputes where nature has been used as proxy. As explored in this article, notwithstanding the principle of permanent sovereignty of states over nature, the focus on ownership rights and exploitative development precepts are starting to be challenged; however, international law remains very fragmented, often polarized and anthropocentric, when it comes to our relationship with nature. From this perspective, RoN represents a real ‘revolution’ to support a total revamp and rethinking of the international legal relationship with nature. The UN Harmony with Nature initiative, the evolution of international human rights law on the rights of Indigenous peoples, the acknowledgement of local communities’ traditional ecological knowledge, and the recently adopted GBF goal of ‘living in harmony with nature by 2050’ are opening up a space for international law to engage more seriously in a profound reform – or at least for creating synergies with some of the ideas advocated under the banner of RoN.
Although these developments have not led to a fully fledged proclamation of nature's rights at the global level, they are creating a framework to develop a less state-centric international law that is opening space to recognize other worldviews and ways of relating with nature. Indigenous peoples are starting to challenge the state-centred, market, and exploitative approach to nature, infusing concepts of relational and kinship relationships with nature using, inter alia, international human rights law.
On this front, the experience of Indigenous peoples with international law is important to bear in mind. Not long ago, Indigenous peoples were the victims of international law, which was used by colonizers to put forward racist theories such as terra nullius, the doctrine of discovery, and other similar legal principles to justify legally the colonization of Indigenous territories.Footnote 127 Despite this history of injustice associated with international law, ‘Indigenous Peoples have challenged the colonial association of international legality with positivism and state-centrism, especially Euro-centrism’.Footnote 128 This was not a seamless process; nor is it the case that international law is now perfectly aligned with Indigenous rights. However, it does show the capacity and potential to challenge and push for deep changes to the international legal architecture.
Similarly, until two decades ago, the idea that local communities might have rights to practise, maintain and perpetuate their traditional ecological knowledge seemed far-fetched, as did the idea that such knowledge could support the international goals of protecting biodiversity. After all, it is only recently that international law has started to care about ‘the environment’, and the idea of recognizing that nature has rights is even more recent.
Despite these advances recognizing the importance of ‘diverse value systems’, when it comes to relationships with nature (as affirmed in the GBF), nature still does not have rights under international law, and crucially nature does not have a voice in international governance. The concepts of duty of care, stewardship, and representation of nature that are central to the RoN movement are still very weak in international law. Some of the RoN initiatives at the national levels are developing innovative systems of nature representation, custodianship duties, and stewardship that could support new interpretations of some of the principles of international law. As explored in Section 4, although the principle of stewardship so far has been lacking in terms of proper integration in international governance, it could nonetheless serve as a platform to infuse concepts of duty of care beyond state sovereignty, as well as supporting the emergence of a new system of nature's voice and representation in international environmental governance. There is still a long way to go, and the political and diplomatic support for developing international law along these lines is still missing.
From this perspective, there is an argument to be made about using RoN principles that are emerging from national examples to infuse the evolution of international law. In terms of future advocacy, what is needed is not necessarily a new international treaty, but rather a more systematic integration of some of the principles behind RoN into existing international law and jurisprudence. This argument is based on different advocacy perspectives. Firstly, there is an element of ‘normative inflation’, creating a very disparate and often fragmented international legal space.Footnote 129 Secondly, in terms of international diplomacy, it is worth bearing in mind the adage that ‘international law is made by the states for the states’, meaning that any new treaty would need a strong coalition of states to engage in the arduous task of international diplomacy required to develop such a treaty.Footnote 130 The argument is political, as it is hard to envisage the diplomatic willingness of states to engage in such an initiative, as well as practical, as it takes years of lobbying and intensive diplomatic engagement to draft new instruments.
One way to create further synergies between RoN and international law might be to support the reinterpretation of existing international legal principles by infusing some of the RoN concepts to challenge the ‘orthodox’ state-centric and exploitative approach to nature. As explored in Section 4 of this article, there is potential for some of the underdeveloped or misinterpreted principles of international law – such the precautionary approach, intergenerational equity, and stewardship – to be reinterpreted and better aligned with the RoN movement. Their apparent anthropocentric orientation may be based more on how they are currently interpreted rather than anything inherent in the norms themselves; international legal scholarship and advocacy therefore should focus on the reinterpretation of international legal concepts in line with RoN principles. Such reinterpretation can (and should) also reflect more diverse perspectives and approaches.
The broad umbrella term of RoN encapsulates very diverse approaches, cultural values, and local worldviews and the relationship with nature. A new treaty might not allow such a diversity of voices and approaches to be expressed; rather, cases on specific areas of international law are likely to be more conducive to that end. There is an argument that RoN is not a monolithic concept and, on the contrary, is developing into a multitude of diverse and localized realities.Footnote 131 These local movements are also facing serious barriers and pushbacks and, although there is momentum behind RoN, it still remains an embryonic and fragile movement. More systematic international legal engagement could certainly support a more global reflection on the relationship between law and nature. International law has much to learn from RoN – but, equally, localized RoN initiatives stand to benefit from a more attuned and supportive international legal framework.Footnote 132
