Maritime security in Indonesia: Towards a comprehensive agenda?

Against the backdrop of Indonesian President Widodo's expressed intention to turn his country in to a maritime nation again, this article examines the way in which the Indonesian state understands and utilises the concept of maritime security. The article achieves this aim by discussing the results of a Training Needs Analysis of key Indonesian state maritime security actors, conducted as part of the first phase of a multi-stakeholder project examining how Indonesia's maritime security capacity can be improved.The article illustrates how key maritime actors within the Indonesian state demonstrate a diverse understanding of what maritime security is, and argues that there is a demonstrable willingness on their part to look beyond a narrow conceptualisation of security in the maritime domain, which is solely focused on military threats and the defence of the state, towards something more comprehensive. Here the Indonesian approach to maritime security mirrors in practice conceptual trends encapsulated in the emergence of maritime security studies. The article concludes that there is the potential for a more comprehensive maritime security agenda to take hold in Indonesia but that this will require continued strategic and policy focus on the maritime domain within the country, alongside an emphasis on partnership building both within the state and between the state and non-state actors.Consistent dialogue around how maritime security is conceptualised would be helpful in supporting these two conditions the article posits, elaborating the value of the human security lens for those interested in a more comprehensive approach to maritime security.     

Ocean governance and maritime security in a placeful environment: The case of the European Union

Adopting a critical geopolitics approach that accounts for the mutually reinforcing link between geo-informed narratives and projection practices, this article proposes that ocean governance and maritime security have translated into states' and regional organisations' increasing control over maritime spaces. This leads to a certain territorialisation of the sea, not so much from a sovereignty and jurisdictional perspective but from a functional and normative perspective. The article starts by discussing the ways oceans have been represented and shows that they are far from a placeless void, both in practice and in discourse. The article then frames the analysis of ocean governance and maritime security within critical geopolitics, and elaborates on the case of the European Union's narrative and practice. It concludes on the mutually reinforcing link between discourse and practice in the field of ocean governance and maritime security in general, and on the consequences for the EU in particular. Scholars working on ocean governance and maritime security are encouraged to challenge the traditional view that oceans are placeless.     

The geopolitical dimension of maritime security

This article discusses the geopolitical dimension of maritime security, which has been neglected by scholars despite the growing number of studies devoted to a variety of aspects related to maritime security. The first step consists in clarifying the definitions of the two concepts; ‘geopolitics’ and ‘maritime security’. Then the article introduces the geopolitical dimension of maritime security from a conceptual perspective, and then analyses three practical examples of maritime security geo-strategies released in 2014. The results demonstrate that states’ and international institutions’ maritime security objectives and interests are indirectly and directly influenced by geographical and geopolitical considerations, although this link is only tacitly acknowledged in official documents. Scholars and practitioners interested in maritime security are encouraged to further engage with this dimension.

ASEAN navies: new missions and old problems

For the Association of Southeast Asian Nations (ASEAN) — Indonesia, Malaysia, the Philippines, Singapore and Thailand — the classical naval missions, protecting the country from seaborne attack and keeping vital sea lanes open, are less important than functions related to new concepts in the law of the sea, coupled with problems which have plagued South-east Asians for hundreds of years. Each of the ASEAN countries now is entitled to claim vastly extended exclusive economic zones (EEZs) and continental shelves, and all but Singapore have been able to extend their maritime territories greatly. However, the old problems of combating piracy, smuggling and illegal barter trade still exist. To these must be added the new patrol functions necessary to protect offshore resources and enforce extended maritime jurisdictional claims.     

Introduction: military and intelligence gathering activities in the exclusive economic zones: consensus and disagreement II

Maritime issues have risen to the forefront of current security concerns. In particular, military and intelligence gathering activities in foreign exclusive economic zones (EEZ) remain controversial. Exacerbating factors include advancing military and intelligence technology, a growing dialectic between coastal States and maritime powers, and new threats like terrorism and weapons of mass destruction. The Honolulu Meeting was part of a Dialogue series on these issues. Topics covered included a summary of the Tokyo Meeting; recent incidents and developments; different perspectives; the proliferation security initiative; implications for the EEZ regime; key terms: range of interpretation; hydrographic surveys and scientific research: differences, overlaps and implications; draft guidelines for military and intelligence gathering in the EEZ; means and manner of implementation and enforcement of any agreed rules; and conclusions and the way forward.     

Manifestation of maritime piracy as an additional challenge for global conservation

Hostile acts against ships and mariners remain a global social and political phenomenon which usually reflects a high degree of socioeconomic vulnerability. The identification of the causes and driving factors behind the deteriorating maritime security has received considerable attention. However, their potential impact upon biodiversity conservation initiatives remains poorly evaluated. In the present study the spatial overlap between biodiversity hotspots and hotspots of hostile maritime acts are explored. The majority of such hostile acts occur in economically vulnerable countries, with the operation of their Marine Protected Areas largely depending on the revenue generated by visitors. Given that hostile maritime acts could cause financial losses and increase social and political instability, they could significantly alter conservation efficiency. Thus, it is critical to consider the way of incorporating maritime security risks into conservation agendas.

SARAL/AltiKa Global Statistical Assessment and Cross-Calibration with Jason-2

The CNES/ISRO mission SARAL/AltiKa was successfully launched on 25 February 2013. It reached its nominal orbit on 13 March 2013. AltiKa is the first altimeter using the Ka-band frequency. This article presents the results of the calibration and validation activities perfromed on the first year of the SARAL/AltiKa mission. The main objective of the article is to assess the SARAL/AltiKa data quality and to estimate the altimeter system performance using GDR products. To achieve this goal, we present mono-mission metrics and compare them with Jason-2 over the same period. Even if these missions do not have the same ground track, precise comparisons are still possible. They allow assessing parameter discrepancies and SSH consistency between both missions in order to detect geographically correlated biases, jumps or drifts. These results show that SARAL/AltiKa data quality is excellent: ocean data coverage is greater than 99.5%, standard deviation at cross-overs is 5.4 cm. The mission therefore fulfills the requirements of high precision altimetry and can be used (in conjunction with Jason-2) to monitor the global mean sea level, ensuring the continuity of the record over ERS/Envisat historical ground track. Possible improvements and open issues are also identified, foreseeing an even better mission performance.
