Abstract
An ecosystem approach to the management of human activities in the marine environment began to feature as a normative concept in international instruments in the 1980s, beginning with the pioneering Convention on the Conservation of Antarctic Marine Living Resources. While an implicit basis for the ecosystem approach can be found in the 1982 Law of the Sea Convention, much of the additional conceptual development at the global level has occurred within the framework of the 1992 Convention on Biological Diversity. The subsequent widespread acceptance of the ecosystem approach has been described as a response to the failure of reactive and fragmented sectoral and zonal approaches to environmental protection and management. A consensus has emerged that a paradigm shift in thinking is needed, whereby traditional modalities of governance are replaced by proactive, integrative and holistic approaches involving adaptive management and greater cooperation between States, international institutions and other stakeholders in order to achieve effective and long-term, coherent implementation of policies across sectors. This chapter will discuss the origins and evolution of the ecosystem approach in international law, which can now be found in a wide range of international and regional instruments, including the regional seas conventions, fisheries management agreements, as well as the ongoing negotiations to develop an internationally legally binding instrument for the conservation and sustainable use of marine biodiversity beyond national jurisdiction. Finally, challenges to the operationalization of the concept in practice will be discussed.

1 Introduction
Despite the importance of biological diversity for life, it is now rapidly declining at alarming rates and marine biodiversity is no exception (IPBES 2019; Grooten and Almond 2018). The 2019 Global Assessment Report on Biodiversity and Ecosystem Services revealed inter alia that natural ecosystems had lost half their area, two thirds of the marine environment had been ‘severely altered’ by human activity and approximately one third of reef forming corals, sharks, and marine mammals are threatened with extinction. The ongoing degradation of ecosystems has forced an acknowledgement of the limitations of previous sectoral and species specific approaches to resource management and environmental protection, leading to the emergence of holistic governance alternatives, which emphasize connectivity and integration (Harrison 2017). The 2016 United Nations (UN) World Ocean Assessment (p. 9) emphasized that “the ocean is a complex set of systems that are all interconnected” and recognized that the development of ocean management had progressed from “no regulation to the regulation of specific impacts, to the regulation of sector-wide impacts and, finally, to regulation taking account of aspects of all relevant sectors.” Out of an increased scientific understanding of the importance of ecosystems and ocean connectivity, the ‘ecosystem approach’ has emerged as a dominant paradigm in international ocean governance.
This chapter will trace the development of the ecosystem approach in international environmental law, from its origins in soft law instruments to becoming endorsed as the main framework for action under the Convention on Biological Diversity (CBD), and its subsequent widespread application in a marine governance context. Finally, challenges to the operation of the concept in practice will be discussed.
2 The Core Elements of the Ecosystem Approach
There is no universally agreed definition of the ecosystem approach in international law (UNGA 2006). The Secretariat of the CBDFootnote 1 has described it as being difficult to define in a simple manner (CBD 2004, p. 3), while de Lucia goes further calling it an “elusive, unstable and contested” concept (2015, p. 93) whose various articulations render the task of finding a meaningful common denominator challenging (De Lucia 2018). The ecosystem approach has been interpreted differently by various environmental institutions and regimes (Platjouw 2016), and is referred to interchangeably as ‘Ecosystem-Based Management’Footnote 2 in international discourse (on definitions see further Delacámara et al. 2020). It is likely that the evolving nature of the ecosystem approach has been a contributing factor to the lack of clarity surrounding its meaning. It is a concept which continues to develop in parallel with scientific understanding of the nature of ecosystems and their core principles (Long 2012).Footnote 3 In fact, Morgera (2017, p. 71) has suggested that the translation of the scientific notion of the ecosystem into a legal construct has provided the basis for the normative development of the ecosystem approach, thereby having a “law-making effect”.
Although it remains underdeveloped in comparison to related approaches such as the precautionary principle (Morgera 2017), an increasing amount of doctrine (see references for a comprehensive list) and technical guidance (e.g. FAO 2003; CBD 2004) has helped clarify the meaning and application of the ecosystem approach, as well as its core elements. Connectivity and integration are central to the idea. An early study by Brunnée and Toope (1994, p. 55) describe it as requiring:
consideration of the whole system rather than individual components. Living species and their physical environments must be recognized as interconnected, and the focus must be on the interaction between different sub-systems and their responses to stresses resulting from human activity.
Amidst the confusion surrounding its meaning, Trouwborst (2009) reminds us that the purpose of the ecosystem approach is the preservation and/or restoration of ecosystem health or integrity. He goes on to extract three strands of generic agreement (p. 28):
(1) The holistic management of human activities, (2) based on the best available knowledge on the components, structure and dynamics of ecosystems, (3) and aimed at satisfying human needs in a way that does not compromise the integrity, or health, of ecosystems.
The work of the UN General Assembly has also been helpful in generating consensus on key components of the ecosystem approach. At the seventh session of the Open-ended Informal Consultative Process on Oceans and the Law of the Sea (UNICPOLOS) in 2006, the resulting report (ICP-7) provided a comprehensive list of elements including inter alia:
- (a)
Emphasize conservation of ecosystem structures and their functioning and key processes in order to maintain ecosystem goods and services;
- (b)
Be applied within geographically specific areas based on ecological criteria ;
- (c)
Emphasize the interactions between human activities and the ecosystem and among the components of the ecosystem and among ecosystems;
- (d)
Take into account factors originating outside the boundaries of the defined management area that may influence marine ecosystems in the management area;
- (e)
Be inclusive, with stakeholder and local communities’ participation in planning, implementation and management;
- (f)
Be based on best available knowledge , including traditional, indigenous and scientific information and be adaptable to new knowledge and experience;
- (g)
Assess risks and apply the precautionary approach ;
- (h)
Use integrated decision-making processes and management related to multiple activities and sectors. (UNGA 2006, para. 6. Emphasis added)
Given that scientific understanding of ecosystems is incomplete, the ecosystem approach has been closely associated with the precautionary principle and adaptive management (Morgera 2017). The precautionary principleFootnote 4 entails taking early, preventative action in response to environmental threats, even in the absence of scientific certainty (Trouwborst 2009), and has been described as an “integral component” of the ecosystem approach.Footnote 5 Adaptive management offers a practical tool for dealing with law’s apparent incompatibility with uncertainty. It provides a “flexible decision-making process that can be adjusted in the face of uncertainties as outcomes from management actions and other events become more understood through careful monitoring of these outcomes” (Williams et al. 2009).Footnote 6 It is often described as an iterative or ongoing learning process (Morgera 2017). The CBD has explained that the ecosystem approach requires adaptive management “to deal with the complex and dynamic nature of ecosystems and the absence of complete knowledge or understanding of their functioning.”Footnote 7
Several international organizations have adopted working definitions of the ecosystem approach and attempted to make progress on elaborating its meaning and operation. The Conference of Parties (COP) to the CBD have defined it in light of the objectives of the Convention (Platjouw 2016)Footnote 8:
a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way. Footnote 9
This definition is concerned with integrationFootnote 10 and equity,Footnote 11 recognizing that humans are an integral component of many ecosystems.Footnote 12 Moynihan (2020) describes integration in the context of the ecosystem approach as meaning integration across sectors, between governance levels, between modern science and traditional methods and between different legal and management strategies. It is noteworthy that no particular spatial unit of scale is included in the CBD definition, rather the scale of analysis and action is to be determined by the problem being addressed.Footnote 13 The International Council for the Exploration of the Seas (ICES) adopted the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR)Footnote 14 definition (de Lucia 2018), which focuses on the management of human activitiesFootnote 15:
The comprehensive integrated management of human activities based on the best available scientific knowledge about the ecosystem and its dynamics, in order to identify and take action on influences which are critical to the health of marine ecosystems, thereby achieving sustainable use of ecosystem goods and services and maintenance of ecosystem integrity.Footnote 16
The OSPAR Commission has stated that “the essence of the ecosystem approach is to allow sustainable exploitation of natural resources while maintaining the quality, structure and functioning of marine ecosystems.”Footnote 17 Long (2012) observes that the rationale for adopting such an anthropogenic approach is that while the ecosystem itself may not be managed, the human activities that interact with and impact upon the ecosystem may be managed with a view to conserving biodiversity. The UN General Assembly has also made it clear that ecosystem approaches “should be focused on managing human activities in order to maintain, and, where needed, restore ecosystem health.”Footnote 18 The anthropocentric focus is also illustrated via the deployment of the ecosystem approach in connection with the conceptual framework of ecosystem services (see further O’Hagan 2020),Footnote 19 seen by many as one of the core elements of the ecosystem approach (de Lucia 2015). Indeed, several definitions of the ecosystem approach refer explicitly to the ecosystem services they provide.Footnote 20
3 Emergence and Development of the Ecosystem Approach in International Law
The ‘ecosystem approach’ as a normative framework is a relatively recent development. The first inklings of the ecosystem approach and of ecosystems becoming an object of conservation and protection in international law can be traced back to the 1970s (see further Long 2012; Platjouw 2016). Several non-binding soft-law instruments,Footnote 21 beginning with the 1972 Stockholm Declaration on the Human Environment, contained formative elements of what would become the ecosystem approach.Footnote 22 The adoption of the 1971 Ramsar Convention on Wetlands of International Importance was also an important environmental milestone of this era.Footnote 23 The notion of ‘wise use’ is at the heart of the Convention and has been explicitly linked to the ecosystem approach.Footnote 24 The focus of the Convention has shifted over time from an original treaty on waterfowl habitat, to the protection of wetlands as an ecosystem, to the ecosystem services provided by wetlands (Dupuy and Viñuales 2015), illustrating the normative evolution of ecosystem protection. The 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)Footnote 25 and the 1979 Convention on Migratory Species (CMS) Footnote 26 also warrant a brief mention: while they are focused on the protection of species, they also refer to the importance of these species within their ecosystems (Platjouw 2016), which has an indirect effect of promoting habitat conservation and thus the conservation of ecosystems (Tarlock 2007). The ecosystem approach is currently taken into account in CITES practice.Footnote 27
Beginning in the early 1980s, specific reference to the ecosystem approach began to appear in a number of international treaties concerning the marine environment (Long 2012). The 1980 Convention on the Conservation of Antarctic Marine Living Resources (CAMLR)Footnote 28 was one of the first instruments to utilize the ecosystem approach as a primary normative framework (Sands et al. 2018) and is generally regarded as a leader in its implementation (Fabra and Gascon 2008).Footnote 29 The CAMLR covers the entire Antarctic marine systemFootnote 30 and has a broad mandate to conserve Antarctic marine living resources, which includes their ‘rational use’ (Arts. II (1) and (2)). This means that ‘harvesting and associated activities’ are permitted in the CAMLR area as long as such exploitation does not endanger the population levels of the harvested species or the ecological relationship as a whole between the marine living resources in the area (Art. II(3)).Footnote 31 Furthermore, the CAMLR prohibits changes to the marine ecosystem which are not potentially reversible over two or three decades (Art. II(3)(c)). The CAMLR is a good illustration of the ecosystem approach in action via its incorporation of basic principles of ecosystem ecology, its recognition of the importance of ecosystem interrelationships and its focus on the various components of the marine ecosystem (de Lucia 2015).
1982 heralded the adoption of the United Nations Convention on the Law of the Sea (UNCLOS),Footnote 32 which provides the overarching legal framework for the governance of the oceans. In contrast to the CAMLR, the ecosystem approach manifests itself in a more implicit manner in UNCLOS (Platjouw 2016). While it does recognize that “the problems of ocean space are closely interrelated and need to be considered as a whole”,Footnote 33 and contains some elements of integrated decision making,Footnote 34 UNCLOS contains few explicit references to the concept of the ecosystem,Footnote 35 and promotes a zonal and sectoral approach to ocean governance (Scott 2015). A critical turning point was the adoption of Agenda 21 at the 1992 United Nations Conference on Environment and Development (UNCED)Footnote 36 which, via its explicit promotion of a holistic approach to oceans management, became a catalyst for further development of the ecosystem approach (Trouwborst 2009). Chapter 17 (para.1) of Agenda 21 underlined the importance of new approaches to marine management, at national, regional, and global levels, “that are integrated in content and are precautionary and anticipatory in ambit”.
The parties to the CBD subsequently approved the ecosystem approach as the primary framework for implementation of its objectives in 1995,Footnote 37 making it the first international treaty to take a holistic, ecosystem-based approach to biodiversity conservation and sustainable use (CBD 2004). The CBD is considered a leader in the adoption of the ecosystem approach and has done more to elaborate the concept than any other regime (de Lucia 2018), capitalizing on previous legal developments in international environmental law such as sustainable forest management.Footnote 38 While the CBD contains a definition of an ‘ecosystem’ as “a dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit” (Art. 2), there is no explicit basis for the ecosystem approach in the text of the CBD.Footnote 39 Due to the lack of development of the notion at an international level, the CBD parties recognized the need to elaborate on its interpretation and application.Footnote 40 Thus, at their fifth meeting in Nairobi, Kenya in 2000, the COP agreed upon a definition (discussed in Sect. 2 above), recommended the implementation of 12 interlinked and complementary principles of the ecosystem approach, known as the Malawi Principles,Footnote 41 and also issued five points of Operational Guidance for their application.Footnote 42 At their seventh meeting in 2004, the COP confirmed that the establishment and maintenance of systems of protected areas play an essential part in implementing the ecosystem approach and achieving the objectives of the Convention.Footnote 43
Malawi Principles
-
1.
The objectives of management of land, water and living resources are a matter of societal choice.
-
2.
Management should be decentralised to the lowest appropriate level.
-
3.
Ecosystem managers should consider the effects (actual or potential) of their activities on adjacent and other ecosystems.
-
4.
Recognising potential gains from management there is a need to understand the ecosystem in an economic context.
-
5.
Conservation of ecosystem structure and functioning, in order to maintain ecosystem services, should be a priority target of the ecosystem approach.
-
6.
Ecosystems must be managed within the limits of their functioning.
-
7.
The ecosystem approach should be undertaken at the appropriate spatial and temporal scales.
-
8.
Recognising the varying temporal scales and lag effects that characterise ecosystem processes, objectives for ecosystem management should be set for the long term.
-
9.
Management must recognise that change is inevitable.
-
10.
The ecosystem approach should seek the appropriate balance between, and integration of, conservation and use of biological diversity.
-
11.
The ecosystem approach should consider all forms of relevant information, including scientific and indigenous and local knowledge, innovations and practices.
-
12.
The ecosystem approach should involve all relevant sectors of society and scientific disciplines.
CBD Operational Guidance for Application of the Ecosystem Approach
-
1.
Focus on relationships and processes within ecosystems.
-
2.
Enhance benefit-sharing.
-
3.
Use adaptive management practices.
-
4.
Carry out management actions at the scale appropriate for the issue being addressed with decentralization to the lowest level, as appropriate.
-
5.
Ensure inter-sectoral cooperation.Footnote 44
After the ecosystem approach was endorsed by the parties to the CBD, it gained widespread recognition,Footnote 45 particularly in a fisheries management context,Footnote 46 where it has been termed the ‘ecosystem approach to fisheries’ (EAF) (UNEP 2016).Footnote 47 The Food and Agriculture Organization of the United Nations (FAO) has promoted the ecosystem approach as best practice.Footnote 48 For example, the 1995 FAO Code of Conduct for Responsible Fisheries recognizes the transboundary nature of aquatic ecosystems (Art. 6(4)) and its provisions have a broad scope to protect target and non-target species as well as the ecosystems associated with those species (Platjouw 2016).The ecosystem approach also became a key feature of the 1995 United Nations Fish Stocks Agreement (UNFSA),Footnote 49 which was designed to apply to fish stocks, regardless of their geographic location and therefore requires States to take into account the transboundary impacts of their decisions.Footnote 50 The precautionary approach is explicitly mentioned in UNFSA and is considered to be an essential component of the EAF.Footnote 51 UNFSA also created an obligation for States to cooperate through Regional Fisheries Management Organizations (RFMOs),Footnote 52 several of which also adopted the ecosystem approach (Sands et al. 2018). However, the actualization of the EAF in this context has been hampered by the fact that RFMOs do not cover the world’s oceans and fishing resources in a comprehensive manner. RFMOs generally manage stocks either on a species specific or geographic basis, thus leaving many areas unregulated and many stocks and species unmanaged (Rayfuse 2016).
Regional seas conventions (RSCs) are generally viewed as being more consistent with an ecosystem approach given that they have geographical as opposed to sectoral scope (Barritt and Viñuales 2016). However in practice they have not been as effective as hoped (Wang 2004); they have limited mandates, which only apply to States which are parties to the relevant treaty, and exclude many relevant human activities from their scope of application (Rochette et al. 2015). Also, most RSCs do not cover the high seas.Footnote 53 Different RSCs tend to emphasize different aspects of the ecosystem approach depending on the regional context (Langlet and Rayfuse 2018; Kirk 2015), however elements such as the precautionary principle,Footnote 54 recognizing the impact of transboundary activities,Footnote 55 the best use of scientific knowledge and advice,Footnote 56 and the involvement of stakeholdersFootnote 57 can be found in several. The ecosystem approach has been explicitly endorsed by the parties to the HelsinkiFootnote 58 and OSPARFootnote 59 Conventions, with a recognition that the marine environment is both an ecosystem and interlocking network of ecosystems,Footnote 60 and it has been described as the ‘overarching principle’ in the OSPAR Commission’s work.Footnote 61 The OSPAR scheme for implementing the ecosystem approach has been described as one of the most highly developed in international environmental law (Long 2012). It embraces an adaptive management approach via its use of a ‘continuous cycle of steps’ which involve setting and coordinating ecological objectives and associated targets and indicators, ongoing management, and regular updating of ecosystem knowledge, research, and advice.Footnote 62
At the global level, the ecosystem approach has featured in the draft text of a new internationally legally binding instrument (ILBI) under UNCLOS on the conservation and sustainable use of marine biodiversity beyond national jurisdiction (BBNJ),Footnote 63 negotiations for which began in September 2018.Footnote 64 The BBNJ negotiations represent a recognition that measures by individual States or regional bodies are not sufficient to conserve the high seas due to the transboundary nature of the ocean. Furthermore, significant regulatory gaps in the existing international governance framework have prevented progress on addressing the increasing threats to high seas biodiversity.Footnote 65 Thus, the development of the ILBI can be viewed as a response to the previously sector specific and uncoordinated approach taken to govern the ocean, thereby demonstrating an endorsement of the ecosystem approach.
4 Operational Challenges
As can be seen from the above discussion, the ecosystem approach has been included in a wide range of ocean instruments. However, its application varies from treaty to treaty with none incorporating all aspects of the approach, likely a result of piecemeal and sectoral development to date (Kirk 2015). The CBD Secretariat has pointed out that there is no single way to implement the ecosystem approach as application will vary depending on the specific context, including local, national, regional, or global conditions (CBD 2004). Therefore, in practical terms, the ecosystem approach is a normative framework, which needs to be tailored to specific circumstances.Footnote 66 This results in a ‘plurality of approaches’ rather than a single ‘true’ version of the ecosystem approach (de Lucia 2015). In 2004, at COP 7, additional rationale and implementation guidelines for the Malawi principles were provided, whereby a mainstreaming of the ecosystem approach into national and regional biodiversity strategies, action plans, policy instruments, planning processes, and sectoral plans was promoted.Footnote 67 Despite these efforts, the principles have not been applied widely in practice as they are viewed as too complex or vague (Langlet 2018; Platjouw 2016).Footnote 68 They also allow much to be decided at a later stage, thus enabling action to be deferred (Kirk 2015).
4.1 Scientific Uncertainty
Reasons for such inertia include the different interpretations of the concept by various actors, as highlighted earlier, and the difficulty in translating the evolving scientific understanding of ecosystems into law (Tarlock 2007). The ecosystem approach is underpinned by a comprehensive scientific knowledge base, however gaps in knowledge, scientific uncertainty, and dynamic multiple-scale ecosystem processes make it difficult to implement in a way that ensures legal stability and predictability (de Lucia 2018). In recognition of the fact that ecosystems change, parties to the CBD stipulated that the ecosystem approach must use adaptive management to anticipate and cater for such changes.Footnote 69 While appearing counter-intuitive at first,Footnote 70 adaptive management models, which enable new knowledge to be incorporated in a tailor made fashion as it becomes available, can provide solutions to the problems of scientific and legal uncertainty (Trouwborst 2009).Footnote 71 In this way, the implementation of the ecosystem approach is also in a constant state of evolution (Long 2012). Despite the allegedly ‘limitless’ legal options for implementing the ecosystem approach (Belsky 1985, p. 763),Footnote 72 Langlet and Rayfuse (2018) point out that the variety and complexity of both natural ecosystems and the institutional, legal, and administrative systems created for their management is what makes the effective implementation of the ecosystem approach so highly challenging. Given the context specific nature of the application of the ecosystem approach, it has been suggested that it is more constructive to view the Malawi principles as an overarching framework of understanding more than an explicit strategy (Langlet and Rayfuse 2018). Kirk (2015) has suggested that the lack of precise prescription as to how the ecosystem approach is to be implemented can be viewed positively, in the sense that it allows for tailored adaptation in response to the needs of particular ecosystems.
4.2 Institutional Fragmentation and Spatial Mismatch
Spatial mismatch between ecological boundaries and governance regimes has been a challenge for the effective operation of the ecosystem approach (Tanaka 2004; Kirk 1999).Footnote 73 The CBD envisages an ecosystem approach whereby the appropriate scale of management action is to be determined by the problem to be addressed.Footnote 74 This is difficult to achieve on a global scale as the ocean is divided into areas under national State jurisdiction and the high seas, also known as areas beyond national jurisdiction (ABNJ), over which no State exercises unilateral control (Harrison 2017). The CBD is focused on the protection of marine biodiversity within the limits of national State jurisdiction,Footnote 75 thus leaving the high seas under the purview of the UNCLOS legal framework and other international and regional agreements.Footnote 76 This has resulted in major governance gaps, which the BBNJ negotiations are now seeking to redress. The challenges which arise due to the lack of spatial fit have been aggravated by the absence of a single overarching global body with the authority to adopt management measures for marine biodiversity conservation that apply to the entire ecosystem (Harrison 2017; Long 2012). As a solution, increased procedural cooperation and linkages between the various existing ocean regulatory regimes have been proposed (Tanaka 2004; Kirk 1999). Successful examples of inter sectoral cooperation on a global level include the work of the International Maritime Organization (IMO) and FAO on tackling Illegal, Unregulated and Unreported (IUU) FishingFootnote 77 and in a biodiversity context, the close cooperation and coordination between the COPs of the CBD, CITES and CMS.Footnote 78 Regionally, institutional cooperation is taking place to coordinate fisheries activities in the North East Atlantic,Footnote 79 in relation to the identification and designation of marine protected areas (MPAs),Footnote 80 ecologically and biologically significant areas (EBSAs),Footnote 81 and large marine ecosystems (LMEs).Footnote 82 However, most examples of inter-sectoral and institutional cooperation tend to occur on an ad hoc basis without overarching coordination. These shortcomings have been recognised within the BBNJ process, and there is agreement on the need to address cooperation and collaboration among different institutions (Harrison 2017), however no clear consensus has yet emerged regarding modalities to achieve this. It also remains to be determined whether there will be a Conference of Parties with global authority as part of the new instrument, however it looks increasingly likely.Footnote 83
5 Conclusion
Despite the challenges associated with the operation of the ecosystem approach, it has increasingly become a staple feature of modern marine management. However, given that most of the work done to flesh out how it can be implemented and applied has occurred on a soft law basis, the normative content of the ecosystem approach has been described as weak and unclear in terms of its obligations on States (Tanaka 2015). It is clear that a more holistic form of governance is a necessary corollary of the ecosystem approach, which will naturally require greater cooperation between States and international and regional institutions, integrated management across sectors, and planning on a variety of levels, including across boundaries (IPBES 2019; UNGA 2006).Footnote 84 Integrated management, with a long-term time frame (CBD 2004), is considered to be essential in order to ensure efficient coordination between organizations and compatibility between policies and activities.Footnote 85 However, its implementation has been hampered by the existing fragmented and decentralised institutional architecture of global ocean governance (Harrison 2017), as well as political and financial challenges (Scott 2015). Its meaning also remains obscure in international law (Scott 2015; Tanaka 2004). Parties to the CBD have acknowledged that the full application of the ecosystem approach remains a ‘formidable task’, especially on a larger scale.Footnote 86 Nevertheless, the soft law developed by CBD parties, including the Malawi Principles and Operational Guidance, continue to remain relevant and applicable. Indeed, Morgera attributes the transformation of the ecosystem approach into a “fully-fledged system of soft law principles and guidelines” to this consensus based normative activity of the CBD parties (2017, p. 71). The BBNJ process represents a timely opportunity for States to tackle many of the challenges discussed in this chapter. While negotiations remain ongoing as of 2019, the design of the instrument and mode by which it provides or creates space for enabling elements (e.g. institutions, guidelines) will have a significant bearing on how the ecosystem approach is translated into practice in the future.

In simple terms, ecosystem services are the benefits humans obtain from ecosystems such as clean air, water, food, fuel, climate regulation, and recreation. See further the Millennium Ecosystem Assessment 2005, which provides a typology of four categories of ecosystem services: supporting, provisioning, regulating, and cultural services.

For example, the definition adopted by the UN Environment Programme (UNEP) is similar to the CBD but replaces ‘conservation’ with ‘sustainable delivery of ecosystem services’. See UNEP (2016, p. 8).

The use of the adjective ‘soft’ to describe the legal status of an instrument is intended to indicate that the instrument is not legally binding, regardless of its content. However, soft law instruments and the conferences and institutions that they create are very influential in international environmental law and have an important normative function. See further PM Dupuy and JE Viñuales (2015, p. 35).

The definition of ‘wise use’ was updated in 2005, taking into account the widespread acceptance of the ecosystem approach: “Wise use of wetlands is the maintenance of their ecological character, achieved through the implementation of ecosystem approaches, within the context of sustainable development”. Ramsar, Conference of the Parties 9 ‘A Conceptual Framework for the wise use of wetlands and the maintenance of their ecological character’ (November 2005) Resolution IX.1 Annex A (2005), para. 22. The definition explicitly cites the ecosystem approach as developed by the CBD (COP5 Decision V/6) and that applied by HELCOM and OSPAR in their Joint Statement in 2003. See further, CM Finlayson et al. (2011, p. 191), E Morgera (2017) highlights an interesting circular evolution here whereby the ecosystem approach elaborated under the CBD built upon the earlier notion of ‘wise use’ contained in the Ramsar Convention.

The 1992 Rio Declaration, op cit, also adopted at UNCED, recognised the “integral and interdependent nature of the Earth” in its Preamble. An important precursor to UNCED was the 1987 Brundtland Commission Report ‘Our Common Future’, which introduced the concept of sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” and linked it to conservation of ecosystems. See Report of the World Commission on Environment and Development, ‘Our Common Future’ 10 March 1987, Chapter 2.

CBD guidance describes inter-sectoral cooperation as a need to integrate the ecosystem approach into different sectors that impact biodiversity, including agriculture, fisheries and forestry and calls for increased communication and cooperation at a range of levels to achieve this e.g. through inter-ministerial bodies or information sharing networks. See CBD-COP 5 Decision V/6 (2000), para. 12 and CBD Guidelines (2004), Annex I.
- 45.
E.g. The UN Convention on the Law of Non-Navigational Uses of International Watercourses (21 May 1997, entered into force 17 August 2014)) created an obligation for States to “protect and preserve the ecosystems of international watercourses”, Arts. 20, 22 and 23. On the ecosystem approach and international water law, see further O McIntyre (2014, 2018), R Moynihan (2017, 2020). It was also endorsed in soft law by the 2002 World Summit on Sustainable Development in its Plan of Implementation, which emphasized the need to “develop and facilitate the use of diverse approaches and tools, including the ecosystem approach” in accordance with Chapter 17 of Agenda 21. See the Johannesburg Plan of Implementation of the World Summit on Sustainable Development (2002), UN Doc. A/CONF.199/20, para. 31 c.
- 46.
For example, the 2001 Reykjavik Declaration on Responsible Fisheries in the Marine Ecosystem recognized the importance of interactions between fishery resources and all components of the ecosystem, and the need to conserve marine environments and called upon States to develop best practice guidelines for introducing ecosystem considerations into fisheries management. See further EJ Molenaar (2002) and M Barange (2003).

The EU, which is a party to the CBD, has embraced the ecosystem approach as a central theme in its marine governance legislation, including the Water Framework Directive 2000/60/EC, the Marine Strategy Framework Directive 2008/56/EC and the Maritime Spatial Planning Directive 2014/89/EU. However, challenges remain at the implementation level, especially in a fisheries context. See further, J Wakefield (2018), N Soininen and FM Platjouw (2018), D Langlet and R Rayfuse (2018, p. 449).

E.g. the Parties to the Antarctic Treaty can only designate protected areas in consultation with the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) as the relevant RFMO in the region and vice versa. In the Mediterranean, cooperation between a regional seas body and a regional fisheries body is illustrated via the Memorandum of Understanding between the UNEP MAP-Barcelona Convention and FAO-GFCM (2012), Annex which includes collaboration on criteria to identify MPAs. See further J Harrison (2017, pp. 281–286).
- 81.
The EBSA process, established under the CBD, has potential to play a useful role in facilitating cooperation in relation to the establishment of MPAs. It is not constrained by boundaries and works via regional workshops involving diverse stakeholder groups representing regional jurisdictions, intergovernmental bodies, non-governmental organizations and indigenous representatives. To date 279 EBSAs have been recognized, encompassing areas of the ocean both within and beyond national jurisdictions. See further DE Johnson et al. (2018).

The LME concept was developed by the United States National Oceanic and Atmospheric Administration (NOAA) as a model to implement ecosystem approaches to assessing, managing, recovering, and sustaining LME resources and environments. Thus far, 64 LMEs have been defined globally. See further https://www.st.nmfs.noaa.gov/ecosystems/lme/; UNEP (2016), H Wang (2004), L Juda (1999). For critique, see J Rochette et al. (2015).
