Abstract:

Africa is currently experiencing a period of economic growth. Its population is growing rapidly and its economies grow and diversify. To be sustainable, such growth requires a large investment in the energy sector. In the case of Cameroon hydroelectric energy is the main source of electrical power whereas the analysis of the geological point of view shows that Cameroon is unique in west-northern of Africa for its active volcanic line (with the last eruption of Mount Cameroon that last erupted in 1999 and 2000) that is a favorable zone for the production of power from geothermal resources. The Cameroon Volcanic Line (CVL) is 100 km wide linear magmatic megastructure oriented N30°E that extends more than 1500 km from Pagalu Island in the Gulf of Guinea to Lake Chad. Along this active volcanic line, more than one hundred and thirty thermal springs are found with the hottest spring at Woulndé (74°C).The aim of this paper is to evaluate the importance of geothermal energy development in the Cameroon Volcanic Line through a geological investigation of areas (Mt. Cameroon and Adamawa) bearing springs with hottest temperatures. This work is a compilation of the bibliographic analysis find at the same topic of research with a source like an International reviewed article, local documents and a websites research. The absence of commitment and enthusiasm from the government is weakening the sector potentiality to be developed either by private sector investments and also foreign investors. Other applications of geothermal energy in Cameroon are also discussed.

Abstract:

Alkaline volcanic activities occurred in the Mt Cameroon at the ocean-continent boundary of the Cameroon Line. It is characterized by a volcanic association of alkali basalts and hawaiites extruded during the late Miocene to Recent times. The major and trace element geochemistry of the Mt Cameroon are consistent with the fractional crystallization of olivine ± clinopyroxene ± plagioclase (± amphibole). Petrographical and mineralogical study reveals the presence of xenocryts (olivine, clinopyroxene and spinel) in Mt Cameroon basalts. Their composition are similar to xenoliths and rocks crystals and they come from cumulates formed in the upper lithospheric mantle. Mt Cameroon magmas were generated near the boundary of garnet and spinel mantle stability domains (60–75 km depth), at the base of the lithospheric mantle that the compositions of the Mt Cameroon magmas are consistent with derivation from a infralithospheric mantle that was metasomatised by carbonatite melts. Basaltic volcanism in the Mt Cameroon occurred probably as a result of minor plume activity coupled with lithospheric extension.

Abstract:

By an application filed on 29 March 1994, Cameroon instituted proceedings against Nigeria, relying on the declarations under Article 36(2) of the Statute of the Court, made by both states without reservations. The dispute, according to the Application, related “essentially to the question of sovereignty over the Bakassi Peninsula”, where, “since the end of 1993”, the Nigerian troops were “occupying several Cameroonian localities”. Cameroon also requested the Court “to determine the course of the maritime boundary between the two states beyond the line fixed in 1975”. In an ‘Additional Application’, filed on 6 June 1994, Cameroon extended the subject of the dispute “essentially to the question of sovereignty over a part of the territory of Cameroon in the area of Lake Chad”, which had become the object of “the official […] claim […] by […] Nigeria quite recently, for the first time”; and also requested the Court “to specify definitely” the whole frontier line from Lake Chad to the sea, and to examine the two Applications as a single case. In its counter-memorial, filed within the prescribed time-limit (18 December 1995), Nigeria raised objections to the jurisdiction of the Court and the admissibility of the Cameroonian claims, whereupon the proceedings on the merits were suspended and the President of the Court fixed 15 May 1996 as the time-limit within which Cameroon might present its observations on the Nigerian objections.

Abstract:

The Cameroon Volcanic Line, a mountain chain located between West and Central Africa, is a region of numerous endemic diversifications, including of puddle frogs (Phrynobatrachus). This study reviews the phylogeny and taxonomy of puddle frogs of the “Cameroon radiation,” which is a clade containing mainly montane but also at least three lowland species. Molecular data revealed a novel evolutionary lineage from high altitudes in the northern part of the mountains. Puddle frogs from the new, minute-sized (SVL < 20 mm) lineage are identified using molecular, morphological and acoustic data and described as two new species, Phrynobatrachus arcanus sp. nov. (Gotel Mountains, Cameroon–Nigeria) and P. mbabo sp. nov. (Tchabal Mbabo, Cameroon). The tadpole of the first species is also described. Phylogenetic analyses placed the new lineage to the proximity of the recently described lowland small-sized taxa (P. horsti, P. ruthbeateae). Based on the inferred phylogeny, we propose five species groups within the Cameroon radiation: P. arcanus, P. chukuchuku, P. ruthbeateae, P. steindachneri, and P. werneri. The taxonomically enigmatic P. hylaios is proposed to be a member of the P. ruthbeateae species group. The basal radiation evolved during the late Miocene with subsequent diversifications occurring during the Pliocene, while closely related terminal taxa originated during the Pleistocene. We recommend that the newly described species are categorized as Critically Endangered due to their limited ranges and because recent surveys did not identify any individuals at the type localities. This further supports the need for conservation interventions in the mountains of Cameroon and Nigeria.

Abstract:

SummaryThe mountains of south-eastern Nigeria are a western extension of the Cameroon mountain range, which is classified as an endemic bird area (EBA). Unlike its eastern extension in Cameroon, most of the ornithological surveys in the western extension of the Cameroon highlands in Nigeria have produced only limited checklists and inventories. There is a clear need for quantitative baseline data so that conservation problems can be identified. Twenty line transects covering a total transect length of 28.8 km were used to survey five sites (Afi Mountain Wildlife Sanctuary, Oban Division and Okwangwo Division of Cross River National Park, Sankwala Mountains and Mbe Mountains) in the westernmost extension of the Cameroon Mountains EBA in south-eastern Nigeria. Vegetation measurements were taken to control for the potential confounding effect of variation in vegetation density and structure on detectability of birds between sites. The 193 bird species recorded in Afi, 158 in Sankwala, 124 in Oban, 100 in Mbe and 73 in Okwangwo Division included most of the Cameroon highlands restricted range species. The results show that the mountains of south-eastern Nigeria are important parts of the Cameroon EBA, particularly Afi Mountain Wildlife Sanctuary. However these sites are threatened by fire and livestock grazing on the hilltops, shifting agriculture on the hillsides and lowlands, and logging for timber in some parts, as well as wildlife hunting for bushmeat.

Abstract:

Tchabal Mbabo in Central Africa is a voluminous volcano massif composed of alkali lava series. K-Ar geochronology data obtained from three samples of basanite - trachyandesite composition defined at least two volcanic activities. The first at end Eocene (38.22 ± 0.80 Ma) and the second during Oligocene (28.88 ± 0.61 and 28.60 ± 0.60Ma). The distribution of different ages along the Cameroon Volcanic Line is difficult to council with any migration of magmatic activity, as previously suggested. The most realistic scenario for the formation of Cameroon Line is that the ascent of lavas has been favored by the crustal discontinuities inherited from the Pan-African orogeny and reactivated during Mesozoic and Cenozoic. ICP MS and ICP AES analyses show that basanite lavas are the result of 2 % melting of sub-lithospheric mantle source containing garnet and phlogopite phases; the trachyandesites are formed by fractional crystallization of K-feldspar, amphibole, clinopyroxene and Fe-Ti oxides.

Abstract:

This study aims at contributing to the debate opposing results-based utility to procedural utility by evaluating the effect of self-employment on job satisfaction. Data is taken from the second Cameroonian Household Survey (2015). Many propensity scores matching techniques were used in addition to models of qualitative variables which led to the conclusion that self-employed workers are more satisfied with work than employees. This satisfaction is felt despite the fact that self-employment generates low income, almost has no job security and calls for long working hours. The high level of autonomy enjoyed by self-employed workers explains this result, which is in line with the procedural utility approach. Furthermore, this study shows that self-employed workers by necessity are less satisfied than self-employed workers by opportunity, meaning that the level of satisfaction varies.

Abstract:

Background: To accelerate access to pediatric HIV care in Cameroon, operational challenges in implementing HIV pediatric care need to be identified. The aim of this study was to assess the knowledge, attitudes, and practices of health care workers regarding pediatric HIV infection in Cameroon. Methods: A descriptive cross-sectional study was conducted over a 4-month period (April to August 2014) in 12 health facilities in 7 regions of Cameroon selected using systematic random sampling. Data were collected from interviews with health care providers and managers using standardized self-administered questionnaires and stored in the ACCESS software. Results: In total, 103 health care providers were included in this study, of which 59 (57.3%) were health workers and 44 (42.7%) community agents. Most of the health workers in charge of HIV pediatric care were nurses, requiring effective medical task shifting that was institutionalized in Cameroon. The knowledge of health care providers in relation to pediatric HIV care was acceptable. Indications for prescription of test for early infant diagnosis were known (96.1%), but their attitudes and practices regarding initiating antiretroviral therapy (ART) in infants less than 2 years (5.2%) and first-line ART protocols (25.4%) were insufficient, due to little information about standard procedures. Conclusion: Capacity building of health care providers and large-scale dissemination of normative national documents are imperative to improve HIV pediatric care in the health care facilities.
