Abstract :
Essentially, this paper aims at considering how the ocean regionalisation may be implemented focusing on the principle of sustainable development, on the subsequent criteria designed by the inter-governmental organisation framework, and on the approaches from the scientific literature. In this respect, a model is proposed, according to which two main stages are identified: (i) the stage of the modern approach to the ocean, which was operated by the modern society and was supported by the culture of modernity; (ii) the stage of the post-modern approach, which has been triggered by the converging inputs from the changes in society and nature. The watershed between these two stages may be located in the 1970s. The investigation may be carried out considering a triangular relationship between (i) the changing ocean reality (ontological dimension), (ii) the representation of this reality (semiological dimension), and (iii) the building up of signified, consisting in theories, meta-theories and values (epistemological and ethical dimensions). In this framework, special relevance is attributed to the interaction between science and policy.
from this basis, how ocean regionalisation had been conceived by oceanography, geography and law is considered focusing on the implications that have arisen in terms of ocean management. Analysis is essentially focused on three questions: (i) how much the conceptual implications of the approach to the ocean regional scale have been underestimated, and how ample the political consequences have been; (ii) why the political designs referring to this spatial scale of the ocean, which have been carrying out since the 1970s, have been marked by a lack of consistency of the legal framework with the prospect of operating sustainable management programmes; (iii) whether, and what kind of, discrepancy has solidified between the legal framework, provided by the 1982 UN Convention on the Law of the Sea (UNCLOS), and the ecosystem-oriented approach to the ocean, designed by the UN Conference on Environment and Development (UNCED).
considerations lead to identify three cardinal needs. First, the need to try lessons from the Regional Seas Programme of the United Nations Environment Programme (UNEP) by carrying out a critical analysis of the conceptual background and methodological endowment which it was based on, and of the subsequent political outcomes. Secondly, an increasing need for scientific approaches supported by the consideration of the ocean as a bi-modular system consisting in ecosystems and organisational patterns, being both modules subject to the impacts from global change and globalisation. Thirdly, a need to design and operate a more effective interaction between science and policy, and, as far as science in itself is concerned, the need to design a more epistemologically-sound interaction between natural and social disciplines.
from this discussion, it is proposed to distinguish the mere ocean area, where the organisational patterns have not yet created a real ocean system, from the ocean region, which differently has acquired the features of an ocean system. These two kinds of spaces may be found in the coastal milieu, extending up to the outer edge of the continental margin, in the deep-ocean, extending seawards from the continental margin, or they may extend across the continental margin and the deep-ocean. Where it is agreed that ocean reality may evolve on the basis of these two reference patterns, the following sequence of conceptual mises-au-point and statements may be considered. •
ean area—This kind of ocean space may solidify in those areas where the ocean is frequented and used in the traditional ways without benefiting from a well-designed organisational pattern. Human presence and resource uses have brought about spatial differentiation but not such a real cohesion which may be only achieved by adopting an organisational plan.
ean region—This occurs only where an ocean area is endowed with such an organisational framework that allows the pursuit of clearly pre-determined objectives in terms of environmental, resource management, and economic development. This is the product of an extensive human interaction with the ocean ecosystem, and of a substantial political approach to the ocean milieu.
it is agreed that ocean reality may evolve on the basis of these two reference patterns, the following sequence of conceptual mises-au-point and statements may be considered: •
ean region and regional strategy—At the present time, ocean regions may be found only in quite limited parts of the ocean world.
nal objective—Where the decision-making centres conform their programmes and actions to the principles and guidelines from UNCED, the objective of each ocean region should be the pursuit of sustainable development on the regional scale.
nable region—This occurs where the regional organisation is primarily based on the protection of the ecosystem integrity, where economic development operates through the optimisation of resource usage, and where social equity, including the access to the natural and cultural heritage of the ocean environment, is guaranteed.
regionalisation—When an individual ocean is subject to the organisational forces that lead to the creation of regions, it can be stated that an ocean regionalisation has occurred.
change—Ocean regionalisation should be viewed as one of the most important consequences of the global, environmental and social change that characterises the present phase of society.
isation—The setting up of a transport and communication global network, together with the associated establishment of global production and consume patterns, of market strategies and social behaviour, may be regarded as the cardinal set of socio-economic factors, which ocean regionalisation is going to increasingly depend on.
ement of the geographical approach—The development of ocean regions encourages to set up effective inter-disciplinary approaches, that primarily should focus on: (i) the consistency of the regional organisation with the regional objectives; (ii) the consistency of the ocean resource use with the protection of the ecosystem, primarily the safeguard of its biodiversity, productivity and resilience; and (iii) the configuration and functions of the decision-making system in guiding regional organisation.
region and ecosystem—The most desirable conditions in terms of optimal ocean organisation on the regional scale occur where the spatial extent of the ocean, which is encompassed by an individual regional management programme, fully coincides with the spatial extent of an ocean ecosystem, or with a set of contiguous ecosystems.
on-making systems—The more the co-operative process between decision-making systems operating in contiguous ocean regions develops, the greater the potential for a holistic political approach to the oceans becomes. The spatial consequences deriving from the interaction between the decision-making centres are of peculiar interest.
