New Directions of China’s Economic Expansion in Africa (The Case of Equatorial Guinea)

The article analyzes China’s cooperation with the Republic of Equatorial Guinea (REG). This country is out of the limelight of attention of scholars and media. Meanwhile, it is one of the leading oil producers in sub-Saharan Africa. Exploitation of oil and gas deposits, beginning in the 1990s, has driven economic growth in Equatorial Guinea. Declining revenue from hydrocarbon production, high levels of infrastructure expenditures, lack of economic diversification, and corruption have pushed the economy into decline in recent years and precluded the improvement in the general population’s living conditions from 2010 to 2014. Country experienced the reduction of foreign financial assistance. In the light of the economic difficulties in the country, as well as in the context of the national economic development plan “Horizons 2020” implemented by the government of Equatorial Guinea, which stipulates the need in investment, the Chinese assistance is of particular importance for REG. The author analyzes China-Equatorial Guinea trade relations and shows that Beijing has become the first partner of REG on export and the second – on import and the largest destination for REG oil exports. The article deals with Beijing’s activities as donor and investor in this African country. China has been increasing its presence in Equatorial Guinea, cooperating with this country in pressing issues such as infrastructure development. REG government seeks to diversify its economy. The government’s “Horizon 2020” initiative tries to build up infrastructure, particularly in the fields of healthcare, water systems, and transportation networks. The Chinese have been engaged in such projects. The article shows that China, which has established a strategic partnership with REG, plays an important role not only in the oil sector of the country, but also in its economy as a whole. The analysis of the problem leads to the conclusion that China makes a significant contribution to the implementation of the REG development plan.

Problems of Agricultural Sector in Oil-Producing Countries of Africa: Equatorial Guinea

The Republic of Equatorial Guinea (REG) is one of the least populated countries in Africa. Prior to the discovery of large oil and gas reserves on its shelf, it was one of the poorest countries in the world in terms of income. Being a typical backward agricultural country with a monocultural export structure, the REG provided the bulk of its foreign exchange earnings through the supply of cocoa beans to foreign markets, the cultivation of which was established on the island of Fernando Po (now Bioco) during the Spanish rule. With the onset of the oil boom, the REG has a new income item, and the economic importance of agriculture in creating GDP fell sharply. With an increase of the inflow of petrodollars, the bulk of the budget funds intended for the development of the economy was spent on the realization and maintenance of expensive infrastructure projects. Stagnant agriculture, unable to meet the needs of the population not engaged in agricultural production, remained outside the scope of the state’s financial and economic policy. Together with the rapidly increasing rural-urban migration this inevitably exacerbated the problem of food security. It was accompanied by a fall in export agricultural production. Since the beginning of the 2000s, the unfavorable global situation in the hydrocarbon market has led to the cessation of the inflow of new foreign investments and a reduction in oil production. The REG authorities have developed a program to diversify the sources of economic growth through the development of industries not related to the exploitation of irreplaceable natural raw materials. First of all, this applies to agriculture, which has a large and underexploited resource potential.

Informativity of borehole geophysical methods in choosing the location of the main structures of the hydroelectric power plant (HPP)

To study the state of the rock massif on the territory of the HPP on the river Vele (Republic of Equatorial Guinea) geophysical surveys using vertical seismic profiling, inter-well seismic survey and inter-well seismic tomography are performed. On the basis of the data obtained, there are significant differences in the state of crystalline rocks on the left-bank and right-bank sections of the dam construction. On the right-bank part of the territory, rock is more secure (about 90 % of the inter-wellbore space under study is characterized by a longitudinal wave propagation velocity ( V P ) of more than 4,500 m/s. On the left bank, for approximately 70 % of the investigated soil thickness V P is more than 4,500 m/s. The rock safety index allowed to obtain a rapid assessment of the state of the rocks in the massif, the rock was divided into four subzones: A — very strong unloading effect with the disintegration of rocks to eluvium, B — a strong manifestation of unloading and weathering, C — a weak manifestation of surface weathering and a moderate Manifestations of unloading, D — rocks are almost non-weathering, there are only signs of linear weathering in subvertical tectonic disturbances and large cracks. According to the results of the inter-well seismic tomography performed, it is also established that the more disrupted rocks are characteristic of the left-bank part of the construction site. Taking into account the obtained data, the plan for the location of the main structures of the dam of the hydroelectric power station is clarified.

Recent import of malaria in a romanian western county

Introduction Malaria is not a concern for Romania nowadays because it was eradicated in 1965, but yearly appear some imported cases especially from people travelling in Africa. For the most of this cases, the etiological agent is Plasmodium falciparum. Timis is the most extensive of the Romanian counties, a western gate of the country from which a lot of people travel abroad. The aim of this study is to inform about some imported cases of malaria discovered in an universitary laboratory in the past decade and to describe two recent, severe cases. Material and methods There were analysed the results of the blood exams (Giemsa-stained thin and thick smears) performed in an universitary parasitological laboratory from 1998 until present and the medical recordings of the last two clinical cases from an universitary Infectious Clinical Hospital. Results Malaria was diagnosed in the 4 of the 6 blood films performed (in 3 cases—75%—the parasitic agent was P. falciparum ). The most recent cases (2006–2007) were: a 50 years old male, christian missionary returned from Uganda who refused the prophylaxis, and a 40 years old male, worker in constructions who returned from Republic of Equatorial Guinea. Both were diagnosed with P. falciparum malaria and both died. Discussion P. falciparum , the main parasitic agent of this imported Romanian cases was found in a similar percentage like in other studies. We perform a comparison between the 2 cases emphasizing on the clinical aspects, complications and the laboratory tests. Although in Romania malaria does not represent a public health concern, the imported cases are difficult to manage in terms of early diagnosis and treatment. Also it is important for people who travel in tropical countries to understand the importance of the preventive measures and to apply them unconditionally.

The blackflies (Diptera: Simuliidae) of Bioko (Republic of Equatorial Guinea) and the Gulf of Guinea with a description of the larvae of the ‘Pomeroy’ form of Simulium cervicornutum

Abstract Like many other organisms, Simuliidae often show a high degree of endemism on oceanic islands, and the Gulf of Guinea, including its islands, is a region of general biogeographical interest in view of the uniqueness of its flora and fauna. This paper presents a comprehensive review of the Simuliidae in the region, and is the first faunistic record of blackflies from Bioko. Simuliidae (larvae, pupae and neonate adults) were collected from Bioko and from around Mount Cameroon and compared with previous findings from Mount Cameroon, Príncipe and São Tomé. Twenty‐seven species are known from the region. Twenty‐five species have been recorded around Mount Cameroon, eight species on Bioko, three species on São Tomé and one species on Príncipe. Two taxonomic ‘forms’ (one on Bioko alone, and one on both Bioko and around Mount Cameroon) and one species (found only on São Tomé) are endemic to the region. A study of the variation in the morphology of Simulium cervicornutum revealed two morphotypes, one from Bioko and around Mount Cameroon and the other from the rest of Africa. The speciation and biogeography of the Simuliidae in the Gulf of Guinea are discussed.

An elementary industry of the chimpanzees in the Okorobikó mountains, Rio Muni (Republic of Equatorial Guinea), West Africa

Sticks are described which have been shaped and used by chimpanzees of the subspeciesPan troglodytes troglodytes in the mountainous region of Okorobiko in central Rio Muni (West Africa). References are also made to the utilization of these sticks for the obtaining of termites of the speciesMacrotermes mulleri andMacrotermes sjostedt. It is indicated that in Rio Muni this elemental industry is known only to some of the groups of these pongids, inhabiting moreover areas relatively close to each other. Also presented is a new map indicating in summary manner the distribution of the principal elemental industries known to chimpanzees in the wild.

Contribution to the ecology of Mandrillus sphinx Linnaeus 1758 of Rio Muni (Republic of Equatorial Guinea).

Some aspects of the ecology and behaviour of mandrills (Mandrillus sphinx) in the wild state are described. It appears that the distribution of this species is considerably more limited than has been admitted till now. It is also probable that mandrills do not live together in the same place as drills (M. leucophaeus). Associations with other primate species are described as well as the status of the dominant male within the group and also the breeding season. Evidence is adduced that the ecology and behaviour are closely the drill.
