Abstract:
Cet article aborde sous un angle anthropologique le sujet des changements alimentaires au Cameroun. Il explore la consommation de la banane plantain, l’un des symboles de la culture des populations autochtones des régions au sud et du centre du Cameroun, à partir du village de Koumou situé à l’arrière-pays de Yaoundé jusqu’à cette même ville. En utilisant des données recueillies en 2004, l’article jette un regard sur les changements dans la consommation de la banane plantain qui sont dus à l’urbanisation. Utilisant une analyse de classe, il présente la question de la différentiation alimentaire qui accompagne le développement des classes sociales urbaines et propose des points théoriques sur le sujet des changements alimentaires en particulier et la consommation en général.

Abstract:
La présente étude vise à caractériser, sur 32 ans entre 1986 et 2018, les mutations spatio-temporelles qu’a connu la zone du Moungo dans la Région du Littoral au Cameroun en raison de l’expansion des plantations bananières et des diverses pressions dans l’utilisation des ressources. Les images satellitaires Landsat de 1986, 2001 et 2018 ont été exploitées à l’aide de la télédétection et des SIG. La classification non supervisée a permis d’obtenir huit classes d’occupation du sol (forêt dense, forêt claire, plantation et champs de cultures, sols nus, zone habitée, savane herbeuse et surface d’eau). La tendance évolutive des formations végétales est essentiellement régressive pour les forêts dense et claire avec une diminution de 336 924,51 ha à 272 887,04 ha entre 1986 et 2018, soit un taux de régression de 16,54% de la superficie totale. Par contre, elle est progressive pour les plantations/champs de cultures, savanes herbeuses, et zones habitées dont les superficies sont passées de 50 231,24 ha en 1986 à 111 325,41 ha en 2018 soit un taux de progression de 15,77%. Les facteurs de cette dégradation sont principalement d’ordres humains (agriculture, surpâturage et démographie galopante) et se traduit par la fragmentation des formations végétales naturelles au profit des surfaces cultivées et des zones d’habitations. Mots clés : Classes d’occupation du sol, facteurs de dégradation, Systèmes d’Information Géographique, Moungo-Cameroun. English Title: Spatio-temporal dynamic of land use change in the Moungo division, Littoral Region, Cameroon : influence on the expansion of banana-based agroforestry systems This study aims to characterize, over a 32-year period between 1986 and 2018, the spatial and temporal changes that occurs in the Moungo division located in the Littoral Region of Cameroon has undergone due to expansion bananas plantation and various pressures in the natural resources use. Landsat satellite images from 1986, 2001 and 2018 were exploited using remote sensing and GIS. The unsupervised classification yielded eight land use classes (dense forest, open forest, plantation and croplands, bare soil, inhabited area, herbaceous savannah and water plans). The evolutionary trend of vegetation formations is essentially regressive for dense and open forest with a decrease from 336 924.51 ha to 272 887.04 ha between 1986 and 2018, indicating a regression rate of 16.54% of the total area. On the other hand, it is progressive for plantations/croplands, herbaceous savannas, and inhabited areas, whose areas increased from 50 231.24 ha in 1986 to 111 325.41 ha in 2018, thus an increment rate of 15.77%. The degradation factors are mainly anthropogenic and include agriculture, overgrazing and increasing human population. As a result, the natural vegetation is being fragmented and transformed into cultivated areas and human inhabitations.Keywords : Land use classes, degradation factors, Geographical Information Systems, Moungo-Cameroon.

Abstract:
Banana bunchy top virus (BBTV; genus Babuvirus, family Nanoviridae) is a serious pathogen of banana (AAA genome) and plantain (AAB genome) (Musa sp.). It is transmitted by the banana aphid (Pentalonia nigronervosa) in a persistent manner (1). In recent years, BBTV has emerged as a major constraint to banana and plantain production in several countries of Africa and had been previously confirmed in viz., Burundi, Central African Republic, Republic of Congo, Democratic Republic of Congo, Egypt, Equatorial Guinea, Gabon, Malawi, and Rwanda (1) and more recently in Mozambique and Zambia (2) and Angola (3). To assess the potential threat of BBTV in West-Central Africa, we conducted surveys in August and September 2008 in 36 major banana- and plantain-producing regions of Littoral, South, Southwest, and Western Provinces of Cameroon. DNA was extracted from 520 plants and tested by PCR with primers specific for a conserved domain of BBTV DNA-R segment (4). A 240-bp DNA fragment specific to the virus was amplified in 31 samples from 18 plantain and 13 banana plants from Southwest, Western, and Southern Cameroon. Among virus-positive samples, symptoms (upright leaf growth, small leaves with pale chlorotic margins that choked the throat of the plant creating the bunchy appearance at the top) typical of bunchy top disease were observed only in banana (cv. Cavendish Williams) from Muea in the Southwest Province. PCR products obtained from the symptomatic and asymptomatic banana (Cavendish Williams) from Muea and Abang, respectively, were cloned into pCR2.1 (Invitrogen, Carlsbad, CA) and two independent clones from each isolate were sequenced in both directions. Pairwise comparison of these sequences showed 100% sequence homology. A comparison of these sequences (Accession No. F580970) with corresponding sequences in GenBank showed 99% nt sequence identity with a BBTV isolate from Angola (Accession No. EU851977) and 96 to 98% identity with BBTV isolates belonging to the South Pacific group (Australia, Africa, South Asia, and South Pacific). However, the BBTV isolate from Cameroon showed 85 to 90% sequence identity with isolates belonging to the Asian group (China, Indonesia, Japan, Taiwan, Philippines, and Vietnam). To further confirm the virus identity, complete nucleotide sequence of the DNA-SCP segment that encodes for the virus coat protein was determined using PCR amplification of viral DNA (1), cloning of products into pCR2.1 vector, and sequencing. The derived sequence (1,075 nt; Accession No. GQ249344) in BLAST search at NCBI database revealed 98% nt sequence identity with coat protein gene of BBTV isolate from Burundi (Accession No. AF148943). These results, together with phylogenetic analysis, indicate that BBTV isolates from Cameroon have greater affinity to the South Pacific group. To our knowledge, this is the first report of BBTV in West-Central Africa. The occurrence of BBTV in the Western and Southern provinces of Cameroon, neighboring north of Gabon, suggests a possible spread of the virus from Gabon. This report also underscores the need to monitor other countries of West Africa for BBTV and enforce quarantine measures to prevent further spread through infected suckers from endemic areas of West and Central Africa.

Abstract:
The main aim of this study is to evaluate the working conditions of some women who supply plantain bananas to markets in Douala. Surveys were conducted among 60 women along National Road 5. This study revealed that the supply chain is dominated by older women (47 years old). Nearly half were married contrary to what one might have thought. Furthermore majority of these women were from the Western Region (76%) and were more experience; to carry out this activity Nevertheless they were faced with difficulties such as Long working hours from 4 am to midnight (than 15 hours) s, braving the risk of aggression and accidents. Their goods were best transported by bus or trucks to the rural markets. In order to purchase this product they are subjected to a lot of challenges and in addition to this, their physical condition must be in order. Another challenge faced by these women is the long waiting hours for trucks or buses to come by. This can take 2–6 hours before the buses arrive. In addition, the activity is mostly appreciated by the actors who do contribute to the economic empowerment of women, because it is profitable. However, they are faced with several constraints such as: theft, insecurity; high cost of transportation; lack of information; poor road infrastructure; police harassment; difficulties to have a warehouse to facilitate the storage and conservation conditions, etc. Due to these constraints, the commercial potential of women is hindered and much lower than it could be.

Abstract:
Dans les pays de la zone tropicale humide, l'elasticite de la consommation de plantain au revenu est positive or au cameroun, la consommation par habitant diminue depuis les annees 70. Cette observation pose la question des determinants de l'offre. Ces derniers pour le plantain, sont lies aux interactions avec le cacao dans la zone forestiere et la capacite d'adaptation des systemes de production et de transfert a une demande en augmentation. La complementarite plantain cacao est mise en evidence sur les fronts pionniers. Elle est fondee sur la valorisation du capital de fertilite des forets et la disponibilite saisonniere du travail des hommes. En revanche, lors d'une augmentation de la pression demographique, la diminution des disponibilites foncieres a pour consequences une concurrence au detriment du plantan, sans un changement des techniques productives. A partir des exploitations actuelles, de tels changements ne peuvent se produire en raison des rapports de prix insuffisants, de la dvision du travail entre hommes et femmes, enfin de l'aversion pour le risque de mise en cause de la securite alimentaire. L'emergence d'exploitations specialisees en plantain suppose comme condition necessaire, des economies d'echelle dans la mise en marche. Or l'observatoire des prix mis en place montrent l'efficacite du systeme de transfert et le caractere justifies des marges commerciales actuelles. Le calcul du prix d'opportunite des facteurs par des modeles de programmation lineaire et la decomposition des couts dans le systeme de transfert, permettent de tester la rentabilite d'une intensification des systemes de production par des indicateurs de competitivite, au niveau des filieres. En fait, l'augmentation des couts de transfert n'est pas suffisante pour justifier une intensification des systemes de production en proximite des villes dans les conditions actuelles. Ces resultats mettent en valeur la necessite pour la recherche agro-economique d'evoluer vers une rationalite procedurale dans un souci
In come elasticity of banana plantain consumption is positive in humid tropical areas, but in cameroon, consumption per inhabitant is decreasing since the seventies. This feature raises the question of determinants of supply. They are determined by the interaction between plantain and cacao in forest areas and by the ability of production and marketing systems to adapt to a growing demand. On "fronts pioneers" we highlight a complementary between cocoa and plantain based on the use of the agro-ecological capital and on the seasonal availability of labour. When demographic pressure increases, decreasing of land access do not lead to technical intensification but rather to over-exploitation of natural resources and to regression of plantain production. Farmers can not intensify the production because of low price ratio, of gender labour division and of risk aversion to food shortage. Emergence of specialised farms on banana plantain would suppose marketing economies of scale, but our observations of prices show that marketing systems are efficient and that commercial margins are normal. Calculation of implicit prices of factors by linear programming and decomposition of marketing costs are used in order to test the profitability at the marketing channel level of production systems intensification. In fact, decreasing in marketing costs due to proximity of towns do not justify intensification of production systems. These results show that agro-economical research has to change toward a "procedural rationality" to be efficient regarding the staple food development issue in subtropical africa

Abstract:
Ce travail est consacre a la valorisation du plantain par la transformation des pulpes en puree ou en farines utilisables en alimentation humaine. Pour faire face au phenomene de brunissement de la pulpe par action de la polyphenoloxydase, nous avons procede a l'etude de cette enzyme. Deux facons dont l'une liee et l'autre soluble ont ete mises en evidence dans la pulpe de plantain. La forme liee, plus importante au stade vert du fruit, evolue vers la forme soluble dans les stades finaux de sa maturation. La presence de la dopamine, substrat naturel de l'enzyme de banane, est signalee pour la premiere fois chez le plantain. La caracterisation de diverses farines obtenues par differents modes de sechage des pulpes de plantain a montre que les farines issues de pulpe ayant subi une inactivation thermique prealable, presentent une bonne capacite d'absorption d'eau et une solubilite importante. Ces farines renferment la plupart des composes biochimiques requis pour la nutrition humaine avec une teneur en lysine disponible relativement elevee. Elles peuvent conduire a la preparation de farines instantanees ou etre incorporees a de la farine de ble pour la preparation de pain. La conservation en frais du plantain dans des emballages de matiere plastique associee a de basses temperatures (14#oc a 16#oc), permet de maintenir le plantain vert pendant au moins 65 jours
