El efecto de las Multinacionales en África : el caso de las petroleras occidentales en el Delta del Níger. Período 2000 – 2006

En África existe un fuerte legado colonial, el cual ha permeado la política y las Relaciones Internacionales de los países de este continente. La relación entre el Estado nigeriano y las Petroleras Occidentales evidencia dicha herencia: del mismo modo demuestra cómo la Ideología del Desarrollo Occidental obstaculiza el alcance de un desarrollo real en Nigeria, y en específico, en el Delta del Níger.

Efectos de la reducción del nivel del Lago Chad sobre la Seguridad Regional (Nigeria, Níger, Chad y Camerún) durante el período de 2000-2010

El Lago Chad ha sido durante varias décadas, una fuente de supervivencia económica para millones de personas que habitan en cuatro Estados a saber; Nigeria, Níger, Chad y Camerún. No obstante, el cambio climático, el aumento acelerado de la población, la explotación insostenible y la mala regulación de los Estados ribereños han sido los principales factores que han dado lugar, en la última década, a la dramática reducción del nivel del Lago Chad. Teniendo en cuenta que los Estados aledaños al Lago, se encuentran inmersos en una Interdependencia Compleja, este nuevo contexto, ha tenido un impacto directo en la región, debido a que ha agravado otras variables económicas, sociales, ambientales y políticas, dejando un ambiente de inseguridad regional. De esta manera, la reducción de la Cuenca del Lago Chad representa una amenaza compartida que vincula estrechamente a Nigeria, Níger, Chad y Camerún, lo que permite vislumbrar la existencia de un Subcomplejo de Seguridad Regional.

Análisis de la presencia de petroleras occidentales y la agudización de conflictos político-económicos en el Delta del Níger. Caso: la Royal Dutch Shell y el Movimiento para la Emancipación del Delta del Níger (MEND) 2006-2010

La región del Delta del Níger es uno de los territorios, sino el principal, en otorgarle a Nigeria numerosas regalías por la exportación de petróleo, sin embargo el escaso beneficio que recibe su población genera conflicto en la región. La alta contaminación provocada por empresas petroleras como la Royal Dutch Shell (RDS), la violación de Derechos Humanos y la estrecha relación que mantiene la multinacional con el Gobierno, se han convertido en los motores del conflicto. Es debido a esto que grupos armados como el Movimiento para la Emancipación del Delta del Níger (MEND), han emprendido acciones con el fin de controlar los recursos, cometiendo robos de petróleo y actos de violencia que constituyen represalias por el trato que la industria petrolera ha dado a la población del Delta. No obstante, el conflicto se ha ido alejando de sus objetivos iniciales en tanto que se ha convertido en un negocio lucrativo, ha producido mayores índices de pobreza y se ha generado un círculo de violencia entre las empresas petroleras, el gobierno nigeriano y los grupos armados. De ahí que el Delta del Níger constituya una región importante no sólo debido a sus altas producciones de petróleo, sino porque además representa una zona altamente compleja que envuelve a ciudadanos, gobiernos y petroleras.

The perception, beliefs and practices toward genitourinary schistosomiasis by inhabitants of selected endemic areas (Edo/Delta States) in south-eastern Nigeria

Well-structured questionnaire on the perception, impression and response to genitourinary bilharziasis (Genitourinary schistosomiasis) was administered and explained in local languages: 'Igbo' 'Esan' 'Ezon' Itshekiri and Bini to 33815 inhabitants of selected endemic areas in south-eastern Nigeria from January, 1999 to December, 2001. Out of this number, 3815 (11.3%) were properly filled and returned. About 42.0% of the inhabitants admitted knowledge of the disease, while 14 (0.4%) knew about the aetiologic agent. About 181 (5.0%) who responded, admitted procuring treatment, while 100 (5.0%) declined to seek treatment of any sort. The relationships between water-bodies and human activities, and infection were well discussed. Amongst those who admitted knowledge of the disease but no knowledge of its etiologic agent, declined seeking treatment of any kind, but believe the disease is a natural phenomenon in ones developmental stage and therefore of no morbidity and mortality. Laboratory analysis of urine, faeces, semen and HVS was employed to assess questionnaire responses, and in some cases, physical examination was utilized to augment laboratory analysis in confirming urinal diagnosis. Haematuria was only directly related to egg count in the early part of life. Females were significantly haematuric and excreted more ova than males (p < 0.05). Headache (43.0%) and fever (31.0%) were major clinical signs while sexual pains (22.0%) were the least.

Technical and scale efficiency of cassava production system in Delta State, Nigeria: an application of Two-Stage DEA approach

The present study examines the level of pure technical and scale efficiencies of cassava production system including its sub-processes (that is production and processing stages) of 278 cassava farmers/processors from three regions of Delta State, Nigeria by applying Two-Stage Data Envelopment Analysis (DEA) approach. Results reveal that pure technical efficiency (PTE) is significantly lower at the production stage 0.41 vs 0.55 for the processing stage, but scale efficiency (SE) is high at both stages (0.84 and 0.87), implying that productivity can be improved substantially by reallocation of resources and adjusting operation size. The socio-economic determinants exert differential impacts on PTE and SE at each stage. Overall, education, experience and main occupation as farmer significantly improve SE while subsistence pressure reduces it. Extension contact significantly improves SE at the processing stage but reduces PTE and SE overall. Inverse size-PTE and size-SE relationships exist in cassava production system. In other words, large/medium farms are technically and scale inefficient. Gender gap exists in performance. Male farmers are technically efficient at processing stage but scale inefficient overall. Farmers in northern region are technically efficient. Investments in education, extension services and infrastructure are suggested as policy options to improve the cassava sector in Nigeria.

Length-weight relationship of benthic bivalves of the Andoni Flats, Niger Delta, Nigeria

The length weight relationship of three benthic bivalves namely, Senilia (= Anadara) senilis (bloody cockle), Tagelus adansonii (knife clam), Tellina nymphalis (soft shell clam) from the Andoni Flats were determined. The bivalves which are of ecological importance were obtained from the intertidal areas of the Andoni Flats. Shell lengths of the bivalves were measured and corresponding dry weight measurements were also taken. The data obtained were then subjected to regression analysis using the FAO-ICLARM Fish Stock Assessment Tools (FiSAT). The length weight relationships obtained from the FiSAT analysis indicated isometric growth for Senilia (= Anadara) senilis, with slope (b) value of 2.942; positive allometric growth for Tagelus adansonii, with a ‘b’ value of 3.395 and negative allometric growth for Tellina nymphalis with ‘b’ value of 2.633. KEYWORDS: bivalves, length-weight, isometric growth, allometric growth, cockle, clam.

Geological Characterisation of Depleted Oil and Gas Reservoirs for Carbon Sequestration Potentials in a Field in the Niger Delta, Nigeria

The injectivity, containment and storage capacity of sandstone reservoirs in a field in the Coastal Swamp depobelt of the onshore eastern Niger Delta were evaluated using wireline logs and seismic data to assess their potentials for carbon dioxide storage and geosequestration. The reservoir formation consists of multilayered alternating beds of sandstone and shale cap rocks. Active seismicity and fracturing intensity are low and growth faults provide the reservoir sealing mechanisms. Three reservoirs were delineated at depths between 3319 m and 3539 m which will keep injected CO2 in a supercritical state. The reservoir depth of at least 800 m, porosity and permeability of more than 10 percent and 20 mD, and a caprock thickness of at least 10 m, in addition to geothermal gradients of 13.46 to 33.66 ºC /km are the ideal conditions for the efficacy of storage. Comparison of the derived reservoir and seal properties such as porosity, permeability, thickness and depth with the minimum recommended site selection criteria shows that the reservoirs are potential candidates for carbon geosequestration with a total theoretical storage capacity of 147MM tons.

Securitización en el desierto: Una respuesta al terrorismo en Malí y en Níger, 2009 - 2013.

Este es un estudio sobre las dinámicas de seguridad en Malí durante el periodo de 2009 a 2013. La investigación busca explicar de qué manera se ha dado un proceso de securitización de los grupos insurgentes frente a la amenaza generada por la proliferación de grupos armados no estatales en el territorio comprendido entre Malí y Níger. Se toma a Níger con el ánimo de ver la existencia de un subcomplejo regional de seguridad entre este país y Malí. De esta manera se afirma que el aumento de las actividades insurgentes y terroristas en la zona compuesta por Malí y Níger se da por la proliferación de actores armados no estatales, entre los cuales se encuentran los grupos seculares e insurgentes Tuareg, las agrupaciones islamistas fundamentalistas y los grupos que se componen entre rebeldes Tuareg, criminales e islamistas, éstos actores han afectado la percepción que tiene Malí sobre su seguridad.

La piratería de Nigeria como una amenaza a la seguridad marítima del Golfo de Guinea (2007-2012). Una aproximación desde el crimen organizado

Desde finales de los 70 la piratería se convirtió en un problema para Nigeria. Con el tiempo adquirió características del crimen organizado y en 2010 se transformó en un problema transnacional, afectando a Estados del golfo de Guinea. Así, a través de una base conceptual, el estudio de caso concluyó que los factores internos –como la pobreza, debilidad estatal y marginalización- y externos –siendo ellos la falta de políticas internas destinadas a las aguas y la ausencia de estrategias marítimas en la región- de la piratería, crearon una dinámica para que dicha actividad se convirtiera en una amenaza a la seguridad marítima del golfo de Guinea, tomando como referencia a Benín y Togo. Siguiendo la línea argumentativa, se demuestra que la búsqueda de una solución a la delincuencia marítima ha generado interacciones de seguridad que sugieren las primeras fases de un posible complejo de seguridad regional.

'Balance of Terror' -- Rival Militias and Vigilantes in Nigeria

Militias and vigilantes that assume public authority by fighting crime reject the laws of the state, yet they have no other set of rules to regulate their activities. Many of them claim to be accountable to their ethnic or religious community on whose behalf they operate. But their communities have found no means to institutionalise control over them. Moreover, there are no institutions to settle conflicts between different militias and vigilantes. On a local level, rival groups have reached informal arrangements. However, these compromises are unstable, as they reflect fragile alliances and shifting balances of power. Leaders of militias and other 'self-determination groups' have suggested organising a conference of all ethnic nationalities in Nigeria in order to design a new constitution that would give militias and vigilantes a legal role and define their authority. But the groups compared in this article – Oodua People's Congress, Sharia Vigilantes, Bakassi Boys, MASSOB, and Niger Delta militias – pursue very divergent interests, and they are far from reaching a consensus on how to contain violence between them.

Exploring the potential of cassava in promoting agricultural growth in Nigeria

Cassava is one of the major food crops in Nigeria, with multiple uses from human consumption to industrial applications. This study explores the potential of cassava in Nigerian agriculture based on a review of cassava development policies; performs a trend analysis of the cultivation area, production, productivity, and real price of cassava and other competing crops for the period 1961–2013; identifies the sources of growth in production; and examines the production constraints at the local level based on a survey of 315 farmers/processors and 105 marketers from Delta State. The results revealed that several policies and programmes were implemented to develop the cassava sector with mixed outcomes. Although cassava productivity grew at 1.5% per annum (p.a.) during the post-structural adjustment programme period (1993–2013), its real price declined at a rate of 3.5% p.a. The effect of yield is the main source of growth in production, contributing 76.4% of the total growth followed by the area effect (28.2%). The cassava sector is constrained by inadequate market infrastructure, processing facilities, and lack of information and unstable prices at the local level. The widespread diffusion of improved tropical manioc selection technologies and investments in market and marketing infrastructure, processing technologies, irrigation/water provision and information dissemination are recommended to enhance the potential of the cassava sector to support agricultural growth in Nigeria.
