Análisis del impacto del fenómeno de la piratería marítima en el comercio marítimo internacional de la región del mar de China (2006-2008)

El fenómeno trasnacional de la piratería marítima se ha convertido en una de las principales amenazas para el desarrollo y el crecimiento del comercio marítimo internacional, especialmente en aquellas zonas que presentan altos flujos comerciales,las cuales de igual forma, se convierten en puntos geográficos favorables para las practicas ilegales de los piratas.

Elementos para una nueva metodología de cálculo de diques verticales

El comercio marítimo actual requiere buques de un tamaño cada vez mayor. Para dar servicio a estos buques los puertos tienen que ofrecer grandes calados y las obras de abrigo están cimentadas cada vez a mayor profundidad, particularmente en el caso de España que es un país con escasos puertos naturales y poca plataforma continental y la mayoría de sus puertos son exteriores. La construcción de obras de abrigo en calados tan grandes (hasta 50 metros de profundidad) resulta sumamente costosa, y dado que a esas profundidades generalmente el oleaje no rompe, la tipología más habitual es la de diques verticales, reflejantes puros, tanto por ahorro de costes como por impacto ambiental. Al ir a mayores calados las olas a las que se enfrentan los diques son cada vez mayores, y esto acusa el desconocimiento exacto de los fenómenos que hidrodinámicos que tienen lugar, y por tanto las deficiencias de los métodos de dimensionamiento de diques verticales empleados. La incertidumbre en la definición de los fenómenos involucrados lleva a la mayoración indiscriminada de las acciones y al sobredimensionamiento de los diques, con el consiguiente sobrecoste, y a otra conclusión más grave: el desconocimiento de los factores de seguridad reales. Esto obliga a continuar profundizando en los fundamentos de los fenómenos observados. La presente tesis se basa en el análisis de datos recogidos por la instrumentación del dique de Botafoc (Ibiza) desde el año 2003. Esta instrumentación es de las que ha ofrecido mediciones de temporales de forma más consistente en todo el mundo. El análisis de los datos conduce a una serie de resultados muy reveladores y novedosos en cuanto a la forma de las distribuciones de los empujes, la influencia del periodo del oleaje sobre las mismas, y la importancia de los flujos inducidos por el oleaje a través de las banquetas de cimentación. Todas las conclusiones alcanzadas están sólidamente justificadas desde el punto de vista teórico. También se ponen de manifiesto otros fenómenos interesantes que no eran objeto de la presente investigación como la importancia del retranqueo del espaldón. El alcance inicial de la tesis pretendía dar explicación a la influencia del periodo del oleaje sobre las distribuciones de presiones, sin embargo la gran cantidad de descubrimientos realizados llevan a pensar en la posibilidad de desarrollar una nueva metodología de cálculo de esfuerzos hidrodinámicos en diques verticales. Esta nueva metodología está en desarrollo por el autor de la presente tesis y será presentada en futuros trabajos. Además del importante avance conceptual del estado de la técnica que supone, otro producto de la investigación ha sido el desarrollo de dos patentes de invención y una tercera aún en desarrollo. Maritime trade nowadays requires ships of increasing size, and ports must go to deeper draughts to shelter those ships. In high depths vertical breakwaters are the most economical alternative; however there are many questions about reflection of waves not yet clarified. This uncertainties drive to oversize breakwaters and the corresponding rise in costs. Moreover the main issue is that safety margins are not known. This thesis is based on the analysis of data collected by instrumentation of the Botafoc breakwater (Ibiza) since 2003, having recorded a wide range of data. The data analysis leads to very interesting discovers such as the shape of the distribution of the pressures, the influence of wave period, and the importance of the wave induced flows through foundation. All conclusions reached are solidly justified from the theoretical point of view. Other interesting phenomena that were not the subject of this research have been revealed such as the importance of crown wall position. The initial scope of the thesis aimed to give explanation to the influence of the wave period on distributions of pressure; however the interesting discoveries made suggest developing a new methodology for calculating hydrodynamic efforts vertical breakwaters. This new methodology is currently under development by the author of this thesis and will be presented in future works. Besides the important conceptual advance the state of the art involved, another product of the research has been the development of two patents.

Crisis Económica en África Occidental: el caso de Dakar, 1929-1939

En este artículo se explora el impacto socio-económico de la crisis internacional de 1929 en Senegal y más concretamente en la ciudad-puerto de Dakar. Se analizan las consecuencias de la dependencia externa y la extroversión económica que caracterizaba a las estructuras productivas coloniales, destacando también la respuesta organizada de los movimientos sociales africanos. Por otra parte, se estudia la evolución de las infraestructuras y actividad portuaria, observando la metropolización regional de Dakar durante este periodo.

Multiple dispersal vectors drive range expansion in an invasive marine species

The establishment and subsequent spread of invasive species is widely recognised as one of the most threatening processes contributing to global biodiversity loss. This is especially true for marine and estuarine ecosystems, which have experienced significant increases in the number of invasive species with the increase in global maritime trade. Understanding the rate and mechanisms of range expansion is therefore of significant interest to ecologists and conservation managers alike. Using a combination of population genetic surveys, eDNA plankton sampling and hydrodynamic modelling we examined the patterns of introduction of the predatory Northern Pacific seastar (Asterias amurensis) and pathways of secondary spread within southeast Australia. Genetic surveys across the invasive range reveal some genetic divergence between the two main invasive regions and no evidence of ongoing gene flow; a pattern that is consistent with the establishment of the second invasive region via a human-mediated translocation event. In contrast hydrodynamic modelling combined with eDNA plankton sampling demonstrated that the establishment of range expansion populations within a region is consistent with natural larval dispersal and recruitment. Our results suggest that both anthropogenic and natural dispersal vectors have played an important role in the range expansion of this species in Australia. The multiple modes of spread combined with high levels of fecundity and a long larval duration in A. amurensis suggests it is likely to continue its range expansion and significantly impact Australian marine ecosystems.

Lusitanian Amphorae in Carthago Nova (Cartagena, Spain): Distribution and Research Questions

The presence of Lusitanian amphorae in the region of Carthago Nova (Cartagena, Spain) has been known for a few years, and yet it has never been the subject of a monographic study. Integrated in the commercial networks of the western Mediterranean, these products circulated within the harbour system of this city between the 1st and the 5th century AD. This paper aims to present a synthesised review of the main Lusitanian imports that were detected: Dressel 14 and Almagro 50, Almagro 51a-b and Almagro 51c. The difficulty in identifying the ceramic fabrics and the scarce documentation regarding some finds pose complex problems. This study extends to the hinterland of the colony and to other nearby settlements, such as Portmán and Puerto de Mazarrón.

Maritime reefer trade in South America: a comparison of the west and east coasts

This issue of the FAL Bulletin examines the scale of maritime reefer trade in South America and the developments made in this area since the 1990s. It also looks at the increase in the capacity of liner services and the relationship between conventional and containerized reefer vessels in terms of trade volume, commodities exported and the destinations for exports from South America.

International trade and maritime transport in the Caribbean

For the countries of the Caribbean, the international trade and transport of goods are more important than for many others in the region (see FAL Bulletin No. 136 Maritime transport in the Caribbean), and the subregion is strongly affected by structural changes in maritime transport (see FAL Bulletin No. 142 The impact of structural changes in liner shipping on Caribbean ports).For these reasons ECLAC's Transport Unit and the Commissions' sub-headquarters in the Caribbean, jointly organized a Meeting of Experts which took place in Port-of-Spain, Trinidad and Tobago, from 14 to 15 September 2000. Twenty-six participants took part, representing different academic, intergovernmental, financial and industrial institutions and organizations.This edition of the FAL Bulletin presents some of the results of this meeting.

Malay Kingship in Kedah : Religion, Trade, and Society

The book probes and examines traditional sources of royal power and control, as well as indigenous socio-political systems in the Malay world. It is focused on the north-western Malaysian Sultanate of Kedah which is acknowledged as the oldest unbroken independent kingship line in the ‘Malay and Islamic world’ with 1,000 years of history. Little scholarly attention has been paid to its pre-modern history, society, religion, system of government and unique geographic situation, potentially controlling both land and sea lines of communication into the remainder of Southeast Asia. It will thus provide the first comprehensive treatment in English, or other languages, on Kedah’s pre-modern and nineteenth century historiography and can provide a foundation for comparative studies of the various Malay states which is presently lacking. The proposed book also sheds much needed light on a range of important topics in Malay history including: Kedah and the northern Melaka Straits history, colonial expansion and rivalry, Southeast Asian history and politics, interregional migration and the influence of the sea peoples or orang laut, traditional Malay socio-political and economic life, Islamic influences and the course of Thai-Malay relations. The book attempts to offer a new understanding, not only of Kedah, but of the political and cultural development of the entire Malay world and of its relationships with the broader forces in both its continental and maritime settings. It argues that Kedah does not seem to follow, and in fact, often seems to contradict what has been commonly been accepted as the “typical model” of the traditional Malay state. Thus it concludes that the ruling dynasty has historically exploited a wide range of unique environmental conditions, local traditions, global spiritual trends and economic forces to preserve and strengthen its political position. The scope and theme of book The Kedah Sultanate is the oldest unbroken independent kingship lines in the “Malay world” with 1,000 years of history, and arguably one of the oldest in the Islamic world. In this study I examine key geopolitical and spiritual attributes of Malay kingship that have traditionally cemented the ruler, the peoples, and the environment. Brief description of the primary audience for the book: There is little written in English or Malay on Kedah’s pre twentieth century history. The available sources only look at certain aspects of Kedah’s history, are outdated or are confined to a specific period often outside the scope of the book. It is therefore anticipated that the readership and market for the book includes: • Scholars of Southeast Asian history, Islam, kingship, trade. • Academics & Historians (including: Asian, Thai history, Islamic, Maritime, Persian, South Asian, Southeast Asian and Colonial) • Libraries • Students, particularly those in Malaysia (especially the states of Kedah, Perlis and Penang), Thailand and Singapore. • Universities • Scholars and students in Political Science & International Relations
