Résumé :

Environmental Impact Assessment (EIA) practice in Cameroon has been plagued with many constraints especially from the infrastructure and EIA resource perspective. The present legal and procedural disposition vis-à-vis EIA in Cameroon is monumental and manifest some clarity of exposition with regards to the practical and fundamental steps for EIA practice in the country. However, a number of impediments still prevail that deter the full efficiency of this legislation. In search for explanations to this trend, this study was conducted to examine the current framework governing EIA in Cameroon implemented in February 2005. Content analysis and interviews with stakeholders in the EIA process were undertaken to identify key barriers associated with EIA practice in Cameroon. The paper maintains that inadequate baseline data, procedural flaws in scoping, exorbitant administrative fees, absence of an appeal procedure, unclear proviso, incompetent personnel and over centralisation of EIA powers are key barriers that appear to impede a healthy EIA practice in Cameroon. In conclusion, it is submitted that for a robust EIA practice to prevail in Cameroon, there is an urgent need for a great deal of focus on the recommendations prescribed within the context of the paper.

Résumé :

The geographic distribution of tungiasis is poorly understood, despite the frequent occurrence of the disease in marginalized populations of low socioeconomic status. To date, little work is available to define the geography of this neglected tropical disease (NTD). This exploratory study incorporated geostatistical modeling to map the suitability for tungiasis transmission in sub-Saharan Africa (SSA). In SSA, environmental suitability is predicted in 44 countries, including Angola, Nigeria, Ghana, Cameroon, Cote de Ivoire, Mali, Ethiopia, the Democratic Republic of the Congo, Kenya, Gabon, Uganda, Rwanda, Tanzania, Zambia, Zimbabwe, Madagascar, and South Africa. In total, an estimated 668 million people live in suitable areas, 46% (304 million) of which reside in East Africa. These evidence-based maps provide vital evidence of the potential geographic extent in SSA. They will help to guide disease control programs, inform policymakers, and raise awareness at the global level. Likewise, these results will hopefully provide decisionmakers with the pertinent information necessary to lessen morbidity and mortality in communities located in environmentally suitable areas.

Résumé :

The present paper deals with Chinese transnational sex labour migration in the city of Douala, the economic capital of Cameroon and the country’s major city. Based on ethnographic research conducted in the prostitution milieu of Douala between 2008 and 2012, and on information collected from both scholarly and popular literature, this contribution shows how the development in this African city of what can be called Chinese sexoscapes has induced the reconfiguration of the local geography of commercialised sex work, which for so long was dominated by native sex workers. The paper also demonstrates how many disgruntled Duala sex workers dealt with the so-called Chinese sex invasion of their city by relocating their business to popular entertainment areas commonly characterised in Cameroon as rue de la joie (street of enjoyment). The research argues that this local geography of sexualities has become a site for asserting ethnic, racial or national identity, and especially a space of both inclusion of people profiled as autochthon populations and the exclusion of those branded foreigners.

Résumé :

AbstractOn 29 March 1994, Cameroon seized the International Court of Justice of a dispute against Nigeria. Inter alia, Cameroon requested the Court "to proceed to prolong the course of its maritime boundary with the Federal Republic of Nigeria up to the limit of the maritime zones which international law places under their respective jurisdictions". Considering that its rights and interests might be affected by the Court's decision on this matter, Equatorial Guinea filed an Application for Permission to Intervene in the Cameroon v Nigeria case. By an order of 21 October 1999 the Court granted Equatorial Guinea's request. This article seeks to examine the question of maritime delimitation as it is presented to the Court in the Cameroon v Nigeria case, taking into account the geographical setting that characterises the Gulf of Guinea, an area where the potential maritime entitlements of five states overlap considerably.

Résumé :

Thesis (DTech (Environmental health))--Cape Peninsula University of Technology, 2017.<br>Western Cameroon is thought to hold rich biodiversity and diverse vegetation types, and contains two important forest reserves: Rumpi Hills Forest Reserve (RHFR), which is lowland to montane forest located in southwestern Cameroon and Kimbi Fungom National Park (KFNP), which is a semi-deciduous and savanna forest located in northwestern Cameroon. These forest blocks form part of the continental Cameroon Mountains. Thus far, few or limited studies have been undertaken at these two sites to characterise their floristic composition, vegetation patterns, biomass, and carbon stock. Hence, the vegetation of RHFR and KFNP were inventoried from February to November 2015 in detail with the view of describing and understanding the biodiversity and vegetation patterns vis-à-vis elevation gradient. This will enable us to answer the main research questions: How does elevation and vegetation patterns influence species composition, diversity, biomass and carbon in selected wet and dry tropical forests of the Congo Basin? Are plant species equitably distributed among life forms and elevations gradient? What are the extent of land cover changes in RHFR and the KFNP? The objectives of this study were: to characterise vegetation patterns, understand how elevation influences species distributions and diversity, and evaluate biomass and carbon stock per hectare. Furthermore, the study intended to assess the vegetation cover changes over the last few decades in RHFR and KFNP in western Cameroon. RHFR and KFNP were chosen as representative forests because limited ecological studies have been carried out on these forests, and each represented a tropical wet or dry forest, respectively. The floristic composition and vegetation patterns of the reserves were studied in 25 1-ha plots in the RHFR and 17 1-ha plots in the KFNP spread along elevation gradient and different vegetation types. In each plot, the dbh of trees and lianas of diameter at breast height ≥10 cm were measured, and dbh of shrubs <10 cm were measured in nested plots of 10 m x 10 m. Remote sensing data (Landsat images) was downloaded from the Global Land Cover Facility (GLCF) and United States Geological Survey (USGS) websites to assess forest cover changes. Forest cover changes over time were compared for both sites. Satellite images from Rumpi Hills (2000 and 2015) and Kimbi Fungom forest (1979 and 2015) were used to compare past and present vegetation (forest cover changes over time). Phytosociological parameters such as basal area, relative density, relative dominance, and relative frequency were used to described forest structure and composition. The statistical program “PAST” version 2.17 was used to calculate species diversity and richness. Allometric equations were used to evaluate above ground biomass and carbon stock.

Résumé :

The most distinctive and characteristic emphasis of early ethology was also what set it off from other post-Darwinian studies of animal behavior. This was the view that behavior varied among species in the same way as did morphological characters and that behavioral differences were as much a product of the evolutionary drama as were the characters that could be measured in museum collections (Tinbergen 1960, Lorenz 1981, Burghardt 1985, Burghardt and Gittleman 1990, Gittleman and Decker 1994). The logical extensions of this view were that behavioral phenotypes could be used in reconstructing phylogenetic histories, that the evolution of behavioral phenotypes could be studied in the same way as the evolution of other classes of traits, and that many of the behavioral differences among taxa reflected underlying genetic differentiation at both the species (Hinde and Tinbergen 1958) and population (Foster and Cameron 1996) levels. Behavior may also initiate evolutionary changes in other attributes of organisms (Mayr 1960, 1965, Wcislo 1989, Gittleman et al. 1996). Although the role of genes in behavioral determination remained controversial for years (see Gottlieb 1992, de Queiroz and Wimberger 1993 for current critiques), many behavior patterns have proven heritable (Mousseau and Roff 1987; papers in Boake 1994b). Indeed, some complex, “species-typical” behavior patterns are performed normally without opportunity for learning (Lorenz 1965). Such behavior patterns can be expressed early or late in development (Lorenz, 1981). At the other extreme, many complex behavioral phenotypes are learned with only slight, if any, genetically based predisposition to perform particular behavior patterns. Between these extremes is a diversity of interactions between genes and environment, including imprinting and complex developmental trajectories produced by interactions between neural development and experience. Many of the currently interesting and controversial questions in the nature–nurture debate do not center around species-typical behavior patterns. Instead, they concern the nature of genetic differences among individuals and populations in the performance of particular behavior patterns and in the ability to modify their performance with experience. Thus the problem must be conceptualized as one in which the interactions of specific genetic constitutions with specific environmental contexts need to be evaluated.

Résumé :

Theoretical discussion of the role of natural selection in shaping behavioral variation in different habitats has been an integral part of the study of animal behavior since the late 19th century. Herbert Spencer (1888) was among the first to argue that migrating populations that fail to adjust to environmental circumstances “are the first to disappear.” A common rationale for comparing populations or related species is the desire to identify behavioral differences that correspond with habitat properties providing different patterns of selection (Tuomi 1981, Riechert 1993, this volume). Behavioral similarities are often ignored or are treated as less interesting because the thrust of the research program emphasizes behavioral differences as an empirical test of the theory of natural selection. Nevertheless, these similarities can be as revealing of evolutionary process as are differences when they reflect behavioral convergence or slow disintegration of behavior under relaxed selection (Coss and Goldthwaite 1995). When populations invade novel habitats, they not only experience new selective regimes; they can also experience relaxed selection on specific behavioral phenotypes. This is particularly common when the new habitat is missing a class of predators that was abundant in the ancestral habitat (e.g., Curio 1975, Pressley 1981). Under relaxed selection, characters may disintegrate, presumably because mutations that result in loss of the phenotype are not at a selective disadvantage. Disintegration is not always observed, however. Instead, behavioral characters are sometimes retained for long periods of time after selection has been relaxed (Coss 1991b, Kaneshiro 1989). Inferring relaxed selection requires that the history of the contrasted populations be relatively well known. Both ancestral selective regimes and behavioral characters must be known if character polarity is to be established. Character polarity must be established to distinguish disintegration from parallel evolution of novel behavior patterns. This often is a problem in population contrasts because differentiation is usually too recent to have resulted in the evolution of enough derived characters for the use of standard cladistic methods of phylogenetic reconstruction, although recent advances in statistical and molecular techniques are promising (Foster 1994, Foster and Cameron 1996). Instead, inference of character polarity has typically relied on geological evidence and comparison with closely related species.
