La mobilité urbaine à Yaoundé comme dans la majorité des agglomérations à forte croissance urbaine en Afrique est dominée par des véhicules de petite capacité comme les taxis collectifs et moto-taxis. Ce phénomène a comme conséquence une augmentation des externalités négatives comme la congestion, les accidents, la pollution, et des coûts monétaires élevés à supporter par les usagers des transports. L'objectif de ce policybrief est d'informer les communautés urbaines en Afrique ou à Yaoundénotamment, que pour résoudre ce dysfonctionnement,il est urgent de redéfinir une nouvelle politique d'occupation du sol à Yaoundé et d'augmenter l'offrequantitative et qualitative en transport publique collectifde massepourréduire la part modale du taxi enle valorisant dans certains types de déplacements comme les dépôts.
School feeding refers to all the conditions through which pupils have access, choose and consume food within the school. School feeding has gained increasing attention in recent years and it is an important route in the process for achieving quality education. The availability of healthy and balanced food in schools is a necessity highlighted in many studies. In developed countries, the institutional framework for school feeding is well developed, schools have canteens, where the meals are prepared and consumed by children according to health standards. The situation is different in developing countries, especially in Cameroon where we carried out a study with an aim to have an overview of the feeding organization in some primary schools in the Yaounde I subdivision. The methodology adopted consist of a survey carried out amongst school stakeholders (school principals, teachers, students and food handlers) and visits to targeted schools. According to the results obtained, 85% of the targeted schools don't have a building space, equipped with all the amenities (Clean water, tables, chairs, toilets) and ready to receive food vendors. Different types of foods are served to children (meals, pastries, fruits, sweets, beverages and icecreams). Unfortunately, those foods are prepared and serve under low hygienic conditions according to standards required for this purpose. Many deficiencies have been highlighted in the framework of our study and in order to mitigate them, the national government should take some actions such as the development of a national policy, the establishment of an adequate institutional framework, the development of a sustainable financing strategy and a capacity building strategy food handlers.
The International Women's Day Celebration started as a socialist political movement, which fought for women's right to vote and better working conditions. Over the years this movement has fought for education, health, poverty, political integration, violence, armed conflict and the aspirations of the girl child. In Cameroon presently, the perception of women about the International Women's Day Celebrations is not fully appraised. A survey was carried out for a week in Biyem-Assi neighborhood after the International Women's Day Celebration (IWDC). The aim of this study was to generate knowledge on a gendered perception of the International Women's day celebration and the practices attached to it. The survey revealed that 50% of women were perceived to celebrate this day for no reason, as most of them did not know the theme for the day. Also, 88.9% of women indulged in a lot of alcohol with most drunk and other malpractices. The findings speculate that the IWDC is about to lose its political flavour if no action is taken. Women and men both accepted that there was a need for women to be educated more on the importance and relevance of the International Women's day and its celebrations. ; Open-Access-Publikationsfonds 2017 ; peerReviewed
International audience ; Floods are considered as the natural hazards that affect the world's major metropolises the most. Thus, the present study aimed at evaluating the sensitivity to flood risks of the Mfoundi watershed (96.5 km2) located in the heart of the Cameroonian political capital in a tropical humid forest zone, more precisely in the South Cameroon plateau. The methodological approach adopted was to identify the factors that most favor the risk of flooding in the area from intense literature review and field investigations; the analysis of these factors and the calculation of the Flood Harzard Index (FHI) using the Analytical Hierarchy Process (AHP) approach coupled with the Geographical Information System (GIS) environment. The results reveal that among the ten parameters of the natural environment (elevation, drainage density, rainfall, slope, distance from the river, topographic humidity, hydraulic conductivity, groundwater level, geology and land cover) selected, the land cover, elevation and the geology are the factors that most influences the flooding phenomenon in the area. The value of Flood Hazard Index (FHI) varied from 4.16 to 9.16, the higher the value, the more sensitive the area is to the risk of flooding. Five main classes of flood susceptibility are highlighted: very low, low, moderate, high and very high, representing 9.50, 26, 23, 22 and 19.5%, respectively of the study area. To validate the efficiency of the obtained flood susceptibility map, the adopted Area Under the Curve (AUC) method shows a very good accuracy (0.84 or 84%). The results of this study constitute a basic tool for decision-making for environmental management by public authorities and decentralised territorial authorities with territorial jurisdiction.

The immediate post-colonial period offered opportunities as well as formidable challenges for former colonies of European powers. While colonial mentalities still pervaded in many European capitals and paternalism remained pervasive throughout the political diplomacy of the period, other perspectives were emerging. Through innovative policy engagements that occurred in the late 1950s and into the 1960s, a new sense of transnational purpose could be seen which presented former colonies with partnership options that were seemingly and practically outside the context of the historic geo-economic imposition. Whereas some European powers continued to exert overly dismissive attitudes to African engagement and society, other approaches experimented with developmental policies that were lauded by both sides at the time. This article will look at the practice and policies of associationism - the outworking of the Yaounde and Lome agreements - and will look at the formative international cooperation policies of the European Community (EC), as it evolved through the period when former European colonies were attaining independence. Finally, it will survey the reasons for the demise of associationism and speculate on the onset of what some have described as "neo-colonalism" (Langan, 2018: 1-32; Nkrumah, 1965). ; Bezpośredni okres pokolonialny przyniósł szanse, a także ogromne wyzwania, dla byłych kolonii mocarstw europejskich. Podczas gdy mentalność kolonialna nadal przenikała wiele europejskich stolic, a paternalizm pozostawał wszechobecny w dyplomacji politycznej tamtego okresu, wyłaniały się także inne perspektywy. Dzięki nowatorskim działaniom politycznym pod koniec lat pięćdziesiątych i sześćdziesiątych XX wieku można było dostrzec nowe poczucie celu ponadnarodowego dające byłym koloniom opcje partnerstwa, które pozornie i praktycznie pozostawały poza kontekstem historycznego przypisania geoekonomicznego. Podczas gdy niektóre mocarstwa europejskie nadal wykazywały zbyt lekceważące podejście do zaangażowania i społeczeństw w Afryce, inne eksperymentowały z polityką rozwojową, która była w tamtym czasie zachwalana przez obie strony. Artykuł ukazuje praktyki i politykę układów stowarzyszeniowych - skutki porozumień z Jaunde i Lome - oraz formatywną politykę współpracy międzynarodowej Wspólnoty Europejskiej (WE), która ewoluowała w okresie, gdy dawne kolonie europejskie osiągały niezależność. Ponadto przeanalizowano przyczyny upadku stowarzyszeniowości i spekulacje na temat początku tego, co niektórzy określają jako "neokolonializm" (Langan, 2018: 1-32; Nkrumah, 1965).

This paper presents the impacts of Nkol'Ossananga sand harvesting on social live and local economy based on field investigations and data analysis. Laboratory analysis of sand samples from the site has shown that the cleanliness of the Nkol'Ossananga sand nears 100%. This means that Nkol'Ossananga sand is pure and clean, most appropriate for house constructions and building engineering. The activity produces incomes to all actors of the chain value and government. Incomes generated are used by artisans to build their houses, buy some electronic devices, and take care of their families or to capitalize in their business investigation. In spite of the positive impacts presumed, Nkol'Ossananga sand harvesting also stands as the origin of many negative impacts including cultural brewing, delinquency, precocious abandon of studies and abandon of agriculture. The exploitation is done with rudimentary tools and poor technics thereby exposing artisans to several risks and illnesses. For sustainable exploitation, a mechanized operation has to be implemented. This kind of exploitation is the one that will improve the working conditions, increase production and incomes of workers as similar as that of government, and also reduces negative environmental impacts. Key words: Nkol'Ossananga sand, rudimentary tools and poor technics, incomes, negative impacts, sustainable exploitation, mechanized operation.

A mesure que le Cameroun se modernise, la question des déchets dans la ville de Yaoundé occupe une place importante dans l'agenda des élites politico-dirigeantes. La croissance démographique rapide et l'industrialisation croissante sont productrices d'une quantité débordante des déchets dont les effets sur la santé et la sécurité des populations se font ressentir. Cet article se veut une réflexion critique du monopole octroyé à HYSACAM dans la gestion technique des déchets dans la ville de Yaoundé. Sur le plan méthodologique, cette réflexion s'appuie sur la recherche documentaire, l'investigation auprès des institutions directement concernées et sur un protocole d'enquête essentiellement qualitative dressé aux populations de Yaoundé. En s'encrant sur l'incrémentalisme, elle met en exergue le tâtonnement et le bricolage qui caractérisent la politique de gestion des déchets dans la ville de Yaoundé. Dit autrement, la politique de gestion des déchets dans la ville de Yaoundé s'inscrit dans un schéma de débrouillardise et de tâtonnement permanent, se caractérisant par des va-et-vient et des essais-recommencements infinis. Cette étude postule qu'on ne saurait envisager, en plein essor de la gouvernance décentralisée, une politique de gestion efficace des déchets en faisant abstraction au « marché » des partenaires techniques, qui suppose une démonopolisation d'HYSACAM dans la gestion technique des déchets dans la ville de Yaoundé. As Cameroon modernizes, the issue of waste in the city of Yaoundé occupies an important place on the agenda of the political-ruling elites. Rapid population growth and increasing industrialization are producing an overflowing quantity of waste, the effects of which are felt on the health and safety of populations. This article is a critical analysis of the monopoly granted to HYSACAM in the technical management of waste in the city of Yaoundé. Methodologically, the research is based on documentary analysis, investigation of the institutions directly concerned and on an essentially qualitative survey protocol drawn up to the populations of Yaoundé. By focusing on the public policy theory of incrementalism, it highlights the trial and error and tinkering that characterize the waste management policy in the city of Yaoundé. In other words, the waste management policy in the city of Yaoundé is part of a scheme of resourcefulness and permanent groping, characterized by back and forth and endless re-starts. This study argues that, in the boom of decentralized governance, an effective waste management policy cannot be envisaged by disregarding the "market" of technical partners, which presupposes a demonopolization of HYSACAM in the technical management of waste in the city of Yaoundé.
The increasing need for animal proteins has led to an interest in non-conventional protein sources such as snails. Although several species of snails are locally reared and highly prized by Cameroonians, there is a lack of information regarding their composition and safety. This work aimed at assessing the chemical composition, the microbiological quality and the total aflatoxins (AFs) and aflatoxin B(1) (AFB(1)) contents of the fleshes from three snails' species traditionally reared in the city of Yaoundé, Cameroon. Samples of Achatina achatina (10), Achatina fulica (10) and Archachatina marginata (10) were randomly collected from a selected farm in Mimboman quarter of Yaoundé and their chemical composition and microbiological quality were evaluated through AOAC and ISO methods, respectively. Their levels of AFs and AFB(1) were assessed using competitive ELISA. The results showed that snail fleshes were a good source of proteins and iron with the one from A. achatina containing the highest protein (15.26%) and iron (7.80 mg/100g) contents. Microbiological analyses revealed that the total aerobic counts of the different samples of snail fleshes were all higher than 6 Log CFU/g thus suggesting a reduced shelf life of the raw product. The safety issue of the snail fleshes is questionable as they contained pathogens such as coliforms and Staphylococcus spp. at levels higher than the norms. Although yeasts and moulds were found in snail fleshes at loads ranging from 3.5 to 4.17 Log CFU/g, their AFs and AFB(1) contents were respectively below 0.22 and 0.44 ppb, values that are lower than that of raw food intended for human consumption. This study demonstrated the potential of snails as an alternative protein source from animal origin and suggests that particular attention should be paid by the government to sensitize the farmers on good hygiene and farming practices and the consumers on good cooking practices.
