This study focuses specifically on the laws and regulations relating to commercial fishing within the Exclusive Economic Zone of South Africa and the impact of illegal fishing (IUU). The goal is to determine how overfishing can be stopped or minimised and ultimately for South Africa to harvest the illegally caught fish in such a way that it becomes part of the South African economy and generates revenue. The study will analyse the international legal instruments applicable and their impact on the development of the South African maritime laws. An in depth look at the relevant South African maritime laws will be vital as to determine if these laws are adequate to protect the fish resources from illegal exploitation and official mismanagement. To see if South Africa’s maritime laws are lacking with other countries a comparison must be done, particularly with a country like Australia that has one of the highest success rates when it comes to combating IUU fishing. It will be found that the international legal instruments and agreements on the use of the sea have afforded rights and powers to coastal states to protect their sea zones, but it will remains the responsibility of each coastal state to determine how it will use these rights and powers to protect its own sea zones. Further it will be shown that South Africa has the necessary legislative measures in place to protect its fish resources, but the problem lies with the implementation of those measures Australia does not only rely on its legislation to stop IUU fishing, but it also uses external methods, that South Africa will have to consider. / LLM (Import and export Law), North-West University, Potchefstroom Campus, 2014

Territorial Disputes in South China Sea Abstract This diploma thesis deals with territorial disputes in the South China Sea and its participants. The aim of the thesis is to describe legal titles of all participants of the dispute and analyse their claims for areas in the South China Sea. The reason of the territorial dispute is based on the proximity of countries and the fact that the South China Sea contains a number of features that are claimed by surrounding countries whose claims exclude. Moreover, one of the participants - China, claims nearly 90% of the whole area. The thesis also describes provisions of the United Nations Convention on the Law of the Sea that are significant for the territorial dispute, as well as, means of the conflict solutions of the dispute provided in the Convention. The Philippines as one of the participants of the dispute decided to initiate arbitrary trial in order to find amicable settlement. The arbitrary tribunal ruled in favour of the Philippines in that matter, however as final chapter provides, China decided to ignore the arbitrary award and continues to supress other countries. Thus, an amicable solution of the dispute seems very unlikely in the near future. Key words South China Sea, exclusive economic zone, territorial dispute

This paper sought to analyse which underlying motives impacted the stances and policies taken by Greece and Türkiye regarding their disputed maritime border. The maritime border consists of two distinct areas, the Aegean Sea, and the Eastern Mediterranean Sea. The analysis chose to study the two areas separately since there are differences between them. The study was conducted through the lens of Morgan and Palmer’s general theory of foreign policy, in which a state either acts reactively to preserve the current situation, or proactively to try and change it. The result of the study shows that both states acted because of security related, economic, and hegemonic motivations as well as to protect their sovereignty and national rights. Security concerns played a significant role in the dispute, as both states deemed the other to be a threat. Because of this, both Greece and Türkiyeacted reactively against each other. At the same time, Türkiye was also found to be more likely to act proactively compared to Greece who often either acted in response to Türkiye or indirectly through its allies such as the EU or Egypt.

本文以中華民國作為研究主體，探討在1982年現代國際海洋法確立之前，「漁業權」此一概念在不同時空背景下的發展過程。本研究首先上溯自清末，探討漁權概念傳入中國的過程以及後來在北京政府(1912-1928)及南京國民政府(1928-1937)的發展，雖然期間政權更迭頻繁，但漁權意識與政策並未隨著政權的更迭而有所轉變，而是彷彿接力賽般，由清末一路承襲自南京國民政府。1937年中日戰爭的爆發，中國沿海省份漸遭日軍佔領，中華民國的漁權發展方暫告一段落。 戰後國際秩序進入重整階段，雖然各國試圖透過國際海洋法會議，制定一具有公信力的國際海洋法，藉此解決諸多國際爭端；然而，在美、蘇冷戰的狀態下，各國對於國際海洋法中的「領海範圍」與「捕魚界限」均難以達成共識。如此也意味著，國際間不論是專屬漁業權或是入漁權雙邊交涉的效力，均遠大於國際法規定，且隨著不同的政治、地理以及國際關係等因素下亦有所差異，因此，本研究針對「專屬漁業權」與「入漁權」進行個案研究，探討中華民國在其中的發展歷程，並藉此比較其中的異同。

Sabe-se que a perda de diversidade nesses sistemas vem crescendo sem ser apropriadamente avaliada. No Brasil, o desnvolvimento de novas fronteiras para a pesca e sua utilização, muitas vezes com pouca regulamentação e/ou fiscalização, tem levado muitos recursos à sobreexplotação. Esta forma de exploração evidencia o uso dos recursos marinhos sem um planejamento adequado. Para que haja tal planejamento, é necessário que se conheçam as vias energéticas e as relações entre os organismos que compõem esse ecossistema. De forma a contribuir para este conhecimento, no presente trabalho foram estudadas a dieta e as relações tróficas de seis espécies de peixes demersais abundantes nas regiões Sudeste e Sul do Brasil: Antigonia capros; Ariomma bondi, Genypterus brasiliensis, Synagrops bellus, Synagrops spinosus e Ventrifossa macropogon. O material provém das coletas do Programa REVIZEE Score-Sul, realizadas entre Cabo Frio (RJ) e Cabo de Santa Marta Grande (SC). Os peixes tiveram a sua dieta analisada por meio do conteúdo estomacal. Além da composição da dieta, foi avaliada a influência da profundidade, do tamanho dos indivíduos, da sazonalidade e do período do dia na obtenção de alimento. Adicionalmente, construiu-se um modelo trófico de balanço de biomassa para avaliar a comunidade demersal da área. Neste estudo foi observado que há um intenso consumo de invertebrados bentônicos, especialmente crustáceos, por todas as espécies, apesar de cada uma apresentar particularidades no comportamento alimentar, como foi constatado nas análises de dieta. Observou-se ainda que as espécies apresentam variações no consumo de alimentos relacionadas à profundidadade, tamanho dos indivíduos e área geográfica onde foram coletadas, e que os fatores que mais causam essas alterações são as variações sazonais. O consumo de invertebrados bentônicos verificado nas análises de dieta e no modelo é maior em espécies de níveis tróficos mais baixos, mas também é significativo em espécies de níveis superiores. Nesta última categoria estão inclusos grandes predadores, como tubarões e atuns, que puderam ser avaliados por meio de dados secundários na construção do modelo. Estes resultados ressaltam a importância da inclusão dos organismos bentônicos nas políticas pesqueiras e planos de manejo, uma vez que se trata de um dos principais pontos de sustentação de todo o ecossistema marinho, sobretudo o demersal / Abstract: The knowledge about marine environments and their rich and diverse ecosystems is improving across the world, but still has gaps, mainly in tropical areas. It is known that the diversity loss is globally increasing without being properly measured. Studies have shown that fisheries are looking for new areas and species aiming to attempt the global fisheries demand. This kind of resource exploitation brings evidence of inadequate fisheries planning. It is necessary the knowledge about the energy pathways and ecosystem relationships to develop appropriate fisheries management for different areas and objectives. Aiming to improve this knowledge and contribute to the appropriate fisheries management, we studied the diet and the trophic relationship of six abundant demersal fishes from Brazilian Southeast and South: Antigonia capros, Ariomma bondi, Genypterus brasiliensis, Synagrops bellus, Synagrops spinosus and Ventrifossa macropogon. The samples were collected during REVIZEE Score-Sul program, between Cabo Frio (RJ) and Cabo de Santa Marta Grande (SC). The fishes were studied based on their gut contents. It was evaluated the diet composition and the influence of depth, season, day time and specimens' size, on food choice. Additionally, we built a trophic model to evaluate the demersal community. We observed intense benthos consumption (especially crustaceans) by all species, despite their specificity. We also observed changes on food consumption according to depth, area and specimen's size, but the main responsible for changes on food consumption are the seasonal variations on the oceanographic dynamics. Benthos consumption is higher in low trophic levels than in high ones, but it is significant in high trophic levels species too, including top predators as sharks and tunas, assessed by secondary data during the model construction. These results show the necessity to include benthos impacts on fisheries management, once they are the main support of the entire marine ecosystem, especially demersal ecosystems / Doutorado / Ecologia / Doutor em Ecologia

The purpose of this dissertation is to demonstrate a new empirical and systemic geopolitical approach to the study of the ongoing territorial dispute in the Arctic resulting from the desire of two nation states, Denmark and Russia, to extend their own northernmost limits of the Exclusive Economic Zone to the central part of the Arctic Ocean. This approach combines geographic, legal and political analytical perspectives with quantitative research design to produce an inter-disciplinary study. Empirical evidence on the long-term socio-geographic development in the region (1993-2013) is provided together with information on particular territorial gains and losses for all decision-makers that arise in a number of potential scenarios (options). Variation in each decision-maker's aggregate national socio-geographic resource, as implied by particular territorial modifications in the central part of the Arctic Ocean, serves as a basis for derivation of nontrivial payoffs on each option in the dispute. These payoffs are introduced into a three-player graph model for conflict resolution (Denmark, Russia, and the World) and stable dispute solutions are suggested on the basis of different combinations of decision-makers' strategies, whose optimality is evaluated as well. Finally, alternative scenarios of...

Thesis (MSc)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: The United Nations Convention on the Law of the Sea (UNCLOS) provides an opportunity for qualifying coastal signatory states to claim extended maritime estate. The opportunity to claim rests on the precept that in certain cases a continental shelf extends beyond the traditionally demarcated two hundred nautical mile (200M) Exclusive Economic Zone (EEZ) mark. In these cases a successful claim results in states having sovereign rights to the living and non-living resources of the seabed and subsoil, as well as the sedentary species, of the area claimed. Where the continental shelf extends beyond the 200M mark, the Foot of the Continental Slope (FoS) has to be determined as one of the qualifying criteria. Article 76 of UNCLOS de nes the FoS as ". . . the point of maximum change in the gradient at its base." Currently Caris Lots is the most widely used software which incorporates public domain data to determine the FoS as a step towards defining the offshore extent of an extended continental shelf. In this software, existing methods to compute the FoS are often subjective, typically involving an operator choosing the best perceived foot point during consideration of a two dimensional profile of the continental slope. These foot points are then joined by straight lines to form the foot line to be used in the desk top study (feasibility study). The purpose of this thesis is to establish a semi-automated and mathematically based three dimensional method for determination of the FoS using South African data as a case study. Firstly, a general background of UNCLOS is given (with emphasis on Article 76), including a brief discussion of the geological factors that influence the characteristics of a continental shelf and thus factors that could influence the determination of the FoS. Secondly, a mathematical method for determination of the surfaces of extremal curvature (on three dimensional data), originally proposed by Vanicek and Ou in 1994, is detailed and applied to two smooth, hypothetical sample surfaces. A discussion of the bathymetric data to be used for application introduces the factors to be taken into account when using extensive survey data as well as methods to process the raw data for use. The method is then applied to two sets of gridded bathymetric data of differing resolution for four separate regions around the South African coast. The ridges formed on the resulting surfaces of maximum curvature are then traced in order to obtain a foot line definition for each region and each resolution. The results obtained from application of the method are compared with example foot points provided by the subjective two dimensional method of computation within the Caris Lots software suite. A comparison of the results for the different resolutions of data is included to provide insight as to the effectiveness of the method with differing spatial coarseness of data. Finally, an indication of further work is provided in the conclusion to this thesis, in the form of a number of recommendations for possible adaptations of the mathematical and tracing methods, and improvements thereof. / AFRIKAANSE OPSOMMING: Die Verenigde Nasies se Konvensie oor die Wet van die See (UNCLOS) bied 'n geleentheid aan kwalifiserende state wat ondertekenaars van die Konvensie is om aanspraak te maak op uitgebreide maritieme gebied. Die geleentheid om op uitgebreide gebied aanspraak te maak berus op die veronderstelling dat 'n kontinentale tafel in sekere gevalle tot buite die tradisioneel afgebakende 200 seemyl eksklusiewe ekonomiese zone (EEZ) strek. In sulke gevalle het 'n suksesvolle aanspraak die gevolg dat die staat soewereine reg oor die lewende en nie-lewende bronne van die seevloer en ondergrond verkry, sowel as die inwonende spesies van die gebied buite die EEZ waarop aanspraak gemaak word. Die voet van die kontinentale tafel (FoS) moet vasgestel word as een van die bepalende kriteria vir afbakening van die aanspraak waar die kontinentale tafel tot buite die EEZ strek. Artikel 76 van UNCLOS defineer die FoS as ". . . die punt van maksimale verandering in die helling by sy basis." Die mees algemeen gebruikte rekenaar sagteware wat openbare domein data aanwend om die voet van die helling te bepaal, is tans "Caris Lots." Die metodes wat in die program gebruik word om die voet van die helling te bepaal, is dikwels subjektief en berus tipies op 'n operateur se keuse van die beste afgeskatte punt van die voet van die helling uit 'n oorweging van 'n twee dimensionele profiel van die kontinentale tafel. Die berekende voet-punte word dan deur middel van reguit lyne verbind om 'n hellingsvoetlyn te vorm. Hierdie voetlyn kan dan in die Suid-Afrikaanse lessenaarstudie (doenlikheidstudie) oor die bepaling van die voet van die kontinentale tafel gebruik word. Die doel van hierdie verhandeling is om 'n semi-outomatiese en wiskundig gebaseerde drie-dimensionele metode te beskryf vir die vasstelling van die FoS, deur as 'n gevallestudie van Suid-Afrikaanse data gebruik te maak. 'n Algemene agtergrond van UNCLOS, met beklemtoning van Artikel 76, word eerstens gegee. 'n Kort bespreking van die geologiese faktore wat die kontinentale tafel beïnvloed en wat gevolglik 'n invloed kan hê op die vasstelling van die voet van die helling, is ingesluit. Tweedens word 'n wiskundige metode, wat oorspronklik in 1994 deur Vanicek en Ou voorgestel is, vir bepaling van die oppervlaktes van maksimale kromming (gebaseer op drie-dimensionele data) in detail bespreek en 'n voorbeeld van 'n toepassing op twee gladde, denkbeeldige oppervaktes word beskryf. Die faktore wat in ag geneem moet word wanneer omvattende dieptemeting data gebruik word, en die metodes wat gebruik word om die rou data te verwerk, word ingelei deur 'n bespreking van die aard van die dieptemeting data wat gebruik is. Die metode word dan toegepas op twee stelle geruite dieptemeting data van verskillende resolusies vir vier afsonderlike streke om die Suid-Afrikaanse kus. Die riwwe wat op die resulterende oppervlaktes van maksimale kromming gevorm word, word dan nagetrek ten einde 'n lyndefinisie van die voet van die kontinentale tafel vir elke streek teen elke resolusie te bepaal. Die resultate verkry uit toepassings van die metode word vergelyk met hellingsvoetpunte soos bepaal deur die subjektiewe twee dimensionele berekeningsmetode in die "Caris Lots" rekenaar-program. 'n Vergelyking van die resultate vir die verskillende data resolusies word ingesluit om die doeltreffendheid van die metode met betrekking tot die hantering van verskillende ruimtelike data resolusies te ondersoek. 'n Aanduiding van verdere werk, bestaande uit 'n aantal aanbevelings vir moontlike aanpassings en verbeterings van die wiskundige en natrek metodes, word ten slotte in die gevolgtrekking van die verhandeling verskaf.

日本的東海政策將對台灣的主權與主權權利造成明顯而立即的影響，因此，日本的東海政策值得深入研究，以維護國家海洋權益。 目前，日本與台灣、中國圍繞在東海的爭端，主要區分為以下三大部分。首先，海域爭端：日本與台灣、中國在東海出現了專屬經濟海域重疊狀況，引發海域劃界糾紛。其次，島嶼爭端：台灣、中國與日本皆主張擁有釣魚台列嶼的主權。第三、油氣爭端：台灣、中國、日本均面臨石油短缺問題，都很重視東海石油的開發與利用。所以，本文選定以日本對於東海的海域政策、釣魚台政策，以及油氣田政策三個息息相關且不可分割的海洋政策面向，來研究日本的東海政策。 本論文從歷史研究途徑的角度，輔以國際海洋法的觀點來探討日本的東海政策，共分為六章：第一章「緒論」說明研究背景、研究動機、研究目的、研究方法，與研究面向。第二章「東海的地緣環境」介紹東海的地緣範疇、經濟價值，與戰略地位。第三章「海域政策」探討日本在東海的海域政策，包括領海、專屬經濟海域、大陸礁層，並說明日本與中國的海域劃界主張。第四章「釣魚台政策」整理歷次釣魚台主權爭議的經緯，並論述爭端國各方主權主張的法理依據，然後指出日本對於釣魚台的政策實踐。第五章「油氣田政策」回顧周圍國家在東海的探採活動，其次討論春曉油氣田事件中，中國的探採經過與日本的因應對策，接著分析中日東海油氣田爭端造成的影響。第六章「結論」歸納主要論點，根據研究結果指出影響日本東海政策的國內外因素，以及日本的東海政策之特點，俾使台灣事先研擬相關對策，進而爭取最大之國家利益與海洋權益。 / Japan's East China Sea policy has a clear and present influence on Taiwan's sovereignty and sovereign rights. Therefore it is important for us to study Japan's East China Sea policy in order to protect our nation's sea rights and interests. At present, the main conflicts between Japan, China and Taiwan in the East China Sea are as follows: First, the maritime delimitation disputes between Japan, China and Taiwan in the East China Sea. Second, Japan, China and Taiwan all declared territorial sovereignty to Tiaoyutai Islands. Third, Japan, China and Taiwan all have oil shortage problems, so they pay much attention to the exploration and the use of petroleum in the East China Sea. Then this thesis selects Japan's sea policy, Tiaoyutai Islands policy, as well as oil and gas fields policy, three closely linked and inalienable sea policy dimensions, to study Japan's East China Sea policy. The thesis discusses Japan's East China Sea policy from the perspective of historical approach and international law of sea. There are six chapters in this thesis: Chapter One makes a description of the background of the study, the purpose of the study, the objective of study, the methodology of the study, and the dimensions of the study. Chapter Two gives an introduction to the East China Sea's surroundings, economic value and strategic position. Chapter Three probes Japan's sea policy, includes territorial sea, exclusive economic zone, continental shelf, and discusses the claims of the maritime delimitation made by Japan and China. Chapter four looks back on the sovereign dispute history of Tiaoyutai Islands, and exhausts the legal basis of the claims made by Japan, China and Taiwan, then points out the practices of Japan in Tiaoyutai Islands. Chapter Five reviews the exploration of the petroleum made by the countries situated around the East China Sea, then discusses China's exploration of Chunxiao oil and gas fields, and the countermeasures of Japan, then analyzes the impact of disputes between China and Japan in the East China Sea oil and gas fields. Chapter Six concludes the main issues, points out the domestic and foreign factors which affect Japan's East China Sea policy, and the characteristics of Japan's East China Sea policy. Thus Taiwan can plan the related countermeasures and strives for our national interests and the sea rights in the future.

每一個沿岸國皆多多少少擁有島嶼，不論是近岸島嶼或洋中島嶼。而全球島嶼面積共3,823,000平方英里，佔地表的百分之七(不包括內陸河流及湖泊中之島嶼)，有些國家甚至完全由島嶼構成。據統計，全球島嶼中，大於1,000平方英里者(相當於牙買加或賽浦路斯的大小)者至少有123個，其中共有61個面積達4,000平方英里(相當於盧森堡的大小)者。這些數據顯示了島嶼地位的重要性，因為在今日，島嶼的存在已不再只是一個單純的地理問題，在國際海洋法上，它不僅可以影響一國海域管轄權(領海、鄰接區、專屬經濟區和大陸礁層)的劃定，甚至足以引起海岸相鄰或相向國家海域管轄權的衝突。解決海域管轄權衝突的最基本辦法，即為針對重疊 區域的「平均分攤」。但此一「平均分配」有時反會因島嶼的存在而導致「不公平劃界」或「疆界線的扭曲」。由於上述結果易使當事國之一方劃得不成比例的海域，[甚至引發更複雜的海域糾紛，因此有必要在海疆劃界中適當控制島嶼的海域管轄權，即---藉賦與島嶼適當之效力，以達公平劃界之目的。本文之研究動機即在於此。而研究目的，則在於就公約規定、學者意見、國際司法判例及國家實踐四者，探討島嶼對海疆劃界的影響，找出解決島嶼造成劃界不公平之方，以及賦與島嶼適當效力之道。本文第一章為「島嶼」的概念性介紹，即何謂島嶼，其定義、種類、存在的形式及形成的過程為何?而一般所謂的島嶼與國際法上的島嶼又有何分別? 此皆為本章重點。第二章為島嶼與領海的關係，討論的焦點包括:(一)領海基線的劃定與島嶼的關係、(二)海灣島嶼的效力、(三)島嶼對領海劃界原則的影響以及(四)島嶼在海岸相鄰或相向國家領海劃界中可得之效力程度等等。三章重點在於介紹島嶼與大陸礁層、專屬經濟區劃界原則之關係，並從公約規定、學者意見、國際司法判例及國家實踐等方面探討島嶼存在時，大陸礁層與專屬經濟區的衡平劃界，以及島嶼在「衡平考量﹞U應得的效力。第四章除介紹「群島制度」的內涵，主要重點則為(一)關於劃定群島基線的國家實踐，以及(二)群島基線的劃定對劃界的影響。此外 南海問題亦是本章重點之一。
