Cette étude décrit la situation et analyse l'importance économique de la traction hippomobile urbaine et périurbaine au Sénégal, à partir du cas de la ville de Thiès. Cent attelages (64 fiacres et 36 charrettes) ont été choisis au hasard et leurs cochers ont été interrogés. Les données collectées ont concerné les cochers et les chevaux, les caractéristiques et la gestion des attelages et enfin les résultats économiques (coûts, recettes et gains). Pour un travail de six jours par semaine, les fiacres et les charrettes ont généré pour le propriétaire de l'attelage un gain monétaire net quotidien moyen équivalent respectivement à 61% (2 202 francs CFA) et 66% (2 779 FCFA) de leur chiffre d'affaires quotidien respectif (3 600 et 4 200 FCFA). Les charrettes sont apparues légèrement plus rentables car leurs tarifs étaient plus élevés. L'importance économique du cheval est illustrée et des recommandations sont proposées pour améliorer ses performances et sa participation à l'économie nationale.

La non maîtrise ou l’ignorance des bonnes pratiques de stockage ou de conservation conduit souvent à des pertes des récoltes en Afrique. Ces dernières peuvent entrainer l’insécurité alimentaire qui est toujours une réalité en Afrique. Ceci illustre que les pratiques culturales et surtout la conservation post-récolte des céréales principaux aliments de base des populations, demeurent un problème majeur en Afrique. Une enquête a été réalisée au Sénégal dans les régions de Tambacounda et de Thiès pour étudier les pratiques culturales des producteurs de sorgho et caractériser la gestion post-récolte dans les zones de production. L’étude a été réalisée auprès de 384 producteurs de sorgho issus de 44 villages. Les zones ont été choisies suivant leur niveau de production et de pluviométrie. La taille de l’échantillon a été déterminée en utilisant l’approximation normale de la loi binomiale. Les résultats ont montré que dans chacune des régions, la proportion d’agriculteur masculin est de 97% et les ethnies dominantes sont les sérères (86%) à Thiès, les peuls et les wolofs (47% et 21%) à Tambacounda. Les semences provenaient principalement de la récolte précédente (10 à 76%) des cas et des distributeurs d’intrants agricoles (2 à 65%). Ces taux diffèrent suivant la région. Les variétés certifiées sont cultivées par 70% des producteurs à Thiès. Les variétés traditionnelles sont utilisées par 98% de ceux de Tambacounda. Cette étude a aussi révélé que les paysans utilisent différents types de séchage à la maison ou aux champs. Parmi eux 79% stockent leur récolte dans des cases, 14% dans des magasins communautaires ,7% dans des greniers sous forme de panicules ou de grains représentant respectivement 22 et 75%. Ces méthodes de prise en charge post-récolte du sorgho diffèrent selon la zone et sont dans certains cas inadéquates. Elles peuvent favoriser la déperdition post-récolte du sorgho et sa contamination par les moisissures, d’où l’intérêt de bien former les acteurs de cette filière.Mots clés : Culture, stockage, céréale, enquête, variété.
English Title: Cultural practices and post-harvest management of sorghum in Senegal
Failure to master or ignore good storage or conservation practices often leads to crop loss or spoilage of food in Africa. These can lead to food insecurity and threaten food safety. As a result, cultivation practices and especially the post-harvest conservation of cereals, the main staple food of the populations, remain a major problem in West Africa. A survey was carried out in Senegal in the regions of Tambacounda and Thies to study the cultural practices of sorghum producers and characterize post-harvest management in the production areas. The study was carried out with 384 sorghum producers from 44 villages. The zones were chosen according to their level of production and rainfall. The sample size was determined using the normal binomial approximation. The results showed that in each of the regions, the proportion of male farmers is 97%, and the dominant ethnic groups are the Serer (86%) in Thies, the Peul and the Wolof (47% and 21%) in Tambacounda. The seeds came mainly from the previous harvest (10 to 76%) of the cases, and from agricultural input distributors (2 to 65%). These rates differ by region. The certified varieties are cultivated by 70% of the producers in Thies. The traditional varieties are used by 98% of those of Tambacounda. This study also revealed that farmers use different types of drying at home or in the fields. Among them, 79% store their harvest in huts, 14% in community stores, 7% in granaries in the form of panicles or grains, representing 22 and 75% respectively. These post-harvest management methods for sorghum differ by area and are in some cases inadequate. They can encourage the post-harvest loss of sorghum and its contamination by molds, hence the importance of properly training the players in this sector.Keywords: Crop, storage, cereal, survey, variety.

L’objectif de cette étude est d’évaluer les effets du programme Caisse d’épargne et de crédit (CEC), à Thiès au Sénégal, sur le niveau d’implication économique et le degré d’intégration sociale des femmes bénéficiaires. Ces bénéficiaires, le groupe expérimental, sont comparées à un groupe témoin composé de femmes qui fréquentent le CPRS, mais ne bénéficient pas des services de ce programme. L’analyse des résultats montre que le programme CEC permet aux bénéficiaires d’avoir une implication économique et une intégration sociale plus forte par comparaison avec ungroupe de non-bénéficiaires. L’introduction des variables de contrôle fait ressortir que la scolarité a la même action déterminantechez les non-bénéficiaires que le programme CEC pour les bénéficiaires. On peut donc conclure que le programme est surtout efficace pour les femmes analphabètes ou peu scolarisées.

Full textAbstract:
Une épizootie de pasteurellose s'est déclenchée dans un élevage semi-intensif de lapins (200 animaux) de race locale, à Thiès (ENSA) au Sénégal, pendant la saison des pluies 1995 (août à octobre). L'épizootie a provoqué la mort de 87 animaux. Les jeunes ont été particulièrement touchés par l'affection. Des symptômes tels que jetage, conjonctivite, perte de l'oeil, otite moyenne et interne étaient observés chez les lapereaux tandis que les adultes manifestaient de la parésie postérieure. Pasteurella multocida, Klebsiella pneumoniae et Pseudomonas aerogenes ont été identifiés. Un antibiogramme a révélé une sensibilité de ces germes au chloramphénicol, à l'association sulfaméthoxazole/triméthoprime et à la colistine. Les températures et l'humidité élevées caractérisant la saison des pluies semblent avoir favorisé l'apparition de la maladie à partir de porteurs sains issus du noyau fondateur de l'élevage. Un traitement à la colistine et au chloramphénicol a été instauré avant une vaccination de tous les animaux contre la pasteurellose.

Pour préciser le mode d’utilisation des phosphates naturels en alimentation animale, deux essais ont été menés au Sénégal. Des zébus Gobra ont été supplémentés avec le phosphate de Taiba (TAP 3 à 4 p. 100 matière sèche de fluor) et celui de Thiès (THP 0,8 à 1 p. 100 MS de fluor), à Dahra et en milieu contrôlé à Sangalcam, au Sénégal en zone sahélienne. Dans l’essai 1, la supplémentation des zébus Gobra a été effectuée sur pâturage naturel au Crz de Dahra pendant trois ans. Les doses appliquées étaient de 50 g de phosphate de Taiba, selon les modes continu et discontinu, respectivement pour les lots 1 et 2 (pour ce dernier lot, la distribution selon le mode discontinu a été abandonnée dans le courant de la deuxième année par suite d’une faible ingestion de phosphate). Elles étaient de 50 et de 100 g de phosphate de Thiès respectivement pour les lots 3 et 4 et de 65 g de poudre d’os pour le lot 5, selon un mode continu pour l’ensemble des lots. Le lot 6 témoin n’a reçu aucun supplément. Les animaux ont été supplémentés en saison sèche pendant huit à neuf mois par an (entre octobre et juin). Dans l’essai 2, quatre lots ont été supplémentés en milieu contrôlé pendant neuf mois. Les bovins ont reçu 50 g de TAP en mode continu, 50 g de TAP en mode discontinu et 200 g de THP en mode continu respectivement pour les lots 1, 2 et 3. Ces animaux ont été comparés au lot 4 témoin non supplémenté. Pour les deux essais, les mesures concernaient le contrôle quotidien de la consommation des phosphates, le suivi pondéral par une double pesée mensuelle des lots et des examens cliniques portant sur l’état général, l’appareil locomoteur et les dents pour détecter les signes de fluorose. Un contrôle biochimique a porté sur l’analyse de la phosphatémie et de la fluorurie. Les résultats ont mis en évidence une bonne tolérance des doses appliquées. L’influence de la supplémentation minérale sur la croissance des animaux n’a cependant pas été significative (P < 0,05). L’innocuité du produit permet de suggérer un test de longue durée en milieu éleveur, plus propice à une démonstration de l’effet bénéfique de la supplémentation minérale sur les performances zootechniques du zébu Gobra.

Pour évaluer l'impact des phosphates naturels sur la survie et la reproduction du zébu Gobra, des essais ont été menés à Dahra au Sénégal, dans la zone sylvopastorale, de janvier 1991 à novembre 1994. Quatre lots de 15 génisses de race Gobra ont été entretenus sur pâturages permanents au Crz de Dahra. Les compléments minéraux distribués étaient composés de 50 g de phosphate de Taiba pour le lot 1, de 100 g de phosphate tricalcique de Lam-Lam (Thiès) pour le lot 2 et de 65 g de poudre d'os pour le lot 3. Le lot 4 témoin ne recevait aucun supplément. Les minéraux ont été distribués tous les jours en saison sèche (huit à neuf mois sur douze) pendant quatre années consécutives. Les mesures effectuées ont concerné la consommation quotidienne des minéraux, le contrôle pondéral et l'enregistrement des mortalités, naissances, saillies et gestations. Un contrôle laitier hebdomadaire a été fait sur les animaux en lactation. Le suivi de l'état de santé du troupeau a été effectué par des examens cliniques mensuels et le suivi quotidien des animaux malades. Les résultats mettent en évidence une innocuité des phosphates testés. Aucun signe d'intoxication au fluor n'a été noté. Une nette efficacité zootechnique des phosphates naturels a été observée. Comparée au lot témoin, la mortalité a été réduite de 50 et 85 % respectivement au sein des lots « poudre d'os » et « phosphate de Thiès ». En novembre 1994 et respectivement pour les lots 1, 2, 3 et 4, le taux de conception était de 25, 53, 57 et 40 %, l'intervalle entre les vêlages de 633, 654, 621 et 704 j et le poids à la naissance de 23,5, 26, 23,9 et 23,8 kg. Ces paramètres ont été améliorés par la supplémentation minérale qui a eu aussi une influence significative (p infff 0,01) sur la production laitière. Ces résultats suggèrent l'utilisation généralisée en milieu traditionnel du phosphate de Taiba et du phosphate tricalcique de Lam-Lam (Thiès), aux doses quotidiennes respectives de 50 g et 100 g en distribution continue pendant la saison sèche (huit à neuf mois sur douze).

Abstract The generation of a fine fraction of sedimentary alumina phosphate before the manufacturing process of phosphoric acid –used as fertilizer– poses a crucial environmental issue related to the large quantities of fines stored for a long time in the wildlife without treatment or recycling in the region of Thiès in Sénégal by the Industries Chimiques du Sénégal (ICS) and the Société Sénégalaise des Phosphates de Thiès (SSPT). This work deals with the use of the fines particles of phosphate generated by the physical processing (crushing, transport and screening) of the raw material by the both mining companies. These fines particles of phosphates cover all the fauna and flora surrounding the sector with whitish dust particularly during the Harmattan, a hot and dry wind, while they can be leached during the rainy season to contaminate groundwater and then cause diseases to the populations who drink that water. Indeed, these materials, which are stored in large quantities as “waste”, and which pollute, the space and the environment, can be recycled as refractory materials useful in manufacturing such as bricks or paving blocks. The purpose of this study is to find, from these discarded fines that are not yet processed, a good and new material in terms of physical and mechanical characteristics that will meet a customary standard. This will allow not only to reduce their potential hazard by reducing the pollution for the consumption of the fines in order to generate a useful material especially in the surrounding villages of the mining sector, but also to employ young people in working age in this fines recycling process, to create jobs and therefore additional economic resources that allow a better life because the majority of the youngsters from these areas are unemployed. The formulation of a well-known mixture containing fines of sedimentary alumina phosphate of particles size ranging between 0.063 mm to 5 mm, with chemical composition similar to that of volcanic slag, sodium silicate called water-glass as binder of mineral elements; and water, led to the manufacturing of geomaterials blocks with 20×10×6 cm3 size by baking them several hours on an oven at the constant temperature of 225°C. The sodium silicate density was 1.4. Good mechanical and physical characteristics were achieved through systematic testing. Strength splitting rupture tests, total water content determination, size measurements of the blocks (length, width and thickness) as well as the loss on ignition on ambient atmosphere were achieved on the blocks after treatment for a complete identification. Average values of 3.03 MPa and 2.5% were obtained as results respectively for the splitting rupture strength and for the total water content. Negative variations of −2.05 mm, −0.59 mm and 1.69 mm on average values were obtained respectively on their length, their width and their thickness for a value of 5.30% of loss on ignition. The blocks are exposed on the fire on their upper surface whilst the heating effect falls of rapidly at the other side. The deduction of the compressive resistance strength from the average value of splitting rupture gave a value of 40.5 MPa. This value testifies very good mechanical resistance strength of the material which is made by the fines of phosphate. These characteristics obtained are compared here to the European Standard values EN 1338 for paving blocks. The values obtained for all the tests attest good manufacturing material. This new material can also be used as refractory materials in the ovens and in pottery materials.

Une étude dans l’objectif de caractériser l’enherbement dans les parcelles cotonnières au Sénégal a été réalisée. Celle-ci a été réalisée grâce à la méthode appelée « tour de champs ». A partir de 139 relevés effectués, 204 espèces réparties en 118 genres appartenant à 35 familles botaniques ont été répertoriées. Les Familles des Fabaceae (22,1%), Poaceae (20,1%), Malvaceae (9,3%) et des Cyperaceae (7,8%) dominent cette flore et représentent près de 60% de l’effectif total. Les Dicotylédones sont dominantes avec 68,6%. Sur le plan agronomique, Hyptis suaveolens, Pennisetum pedicellatum, Digitaria horizontalis, Dactyloctenium aegyptium et Kyllinga squamulata constituent les adventices majeures. L’analyse de l’indice partiel de nuisibilité révèle que 47 espèces sont potentiellement nuisibles dont dix constituent les plus nuisibles aux cotonniers dans le bassin cotonnier du Sénégal. Une gestion efficace contre ces espèces devrait être envisagée pour réduire les pertes de rendement dues aux adventices.Mots clés : Adventices, nuisibilité, infestation, cotonnier, rendement, Sénégal.
English Title: Degree of weed infestation in Senegal's cotton basinIn Senegal, weeds are one of the major constraints to increasing agricultural production. A study was carried out to characterize grass cover in cotton plots in Senegal. This was carried out using the method known as "tour de champs". Based on 139 surveys, 204 species in 118 genera belonging to 35 botanical families were identified. The Families Fabaceae (22.1%), Poaceae (20.1%), Malvaceae (9.3%) and Cyperaceae (7.8%) dominate this flora and represent nearly 60% of the total number of species. Dicotyledons are dominant with 68.6%. Agronomically, Hyptis suaveonlens, Pennisetum pedicellatum, Digitaria horizontalis, Dactyloctenium aegyptium and Kyllinga squamulata are the major weeds. Analysis of the partial harmfulness index reveals that 47 species are potentially harmful, ten of which are the most harmful to cotton plants in the cotton basin of Senegal. Effective management against these species should be considered to reduce yield losses due to weeds.Keywords: Weeds, pests, infestation, cotton, yield, Senegal.

AbstractThis analysis of Senegal environmental law is based on the example of a local context of rural communities located in the eastern Senegal area where the Bassari population is settled. The environmental legislation in Senegal does not seem to fit the local and rural realities. Our approach proposes to build a patrimonial legal system involving responsibility of the different actors in decision making. Law should be elaborated consensually by the different stakeholders, so that it will be easier to implement. We have conceived a «local environmental agreement» in order to link the local (legitimate) and national (legal) requirements. The aim of this article is to develop a conceptual and practical basis for legal and institutional patrimonial management of the natural resources.

Full textAbstract:
Fluctuations of colonial policies toward territorial integrity were not without effects, first on the people of these colonies and then on the organization of their own administration. A case in point is the tortuous history of colonial administration in Upper Volta (now Burkina Faso). Created in 1919 out of the oversized Haut-Sénégal-Niger—which extended from the Sénégal river to lake Chad—in order to rationalize the administration Upper Volta survived as an autonomous colony until January 1933, when it was officially dismembered. The northwestern part (i.e., Ouahigouya) was ceded to the French Sudan, the central and southwestern regions (Mosi and Bobo) to Côte d'Ivoire, and a small portion of the eastern portion (Fada N'Gourma) to Niger. After harsh negotiations the colony of Upper Volta was recreated in 1947. Researchers who have worked on this part of the French empire know that every adjustment brought to the administrative arrangement also caused personnel and documents to be displaced to the new centers—Abidjan, Niamey, or Bamako.This institutional constraint on the organization of complete sets of archival documents for the study of the region's past has been strengthened by a well-known post-independence symptom: bureaucratic plethora. Indeed Burkina Faso is probably the only country in the world to possess more archivists than organized archives. The Direction des archives, with its dozen archivists in the 1980s, had not produced a single inventory of what could be found in the capital (Ouagadougou) or in the regions, although important work had been done by individual archivists appointed to specific Ministries or by expatriate researchers.

One of the basic debates in African development is whether agriculture can be the instrument for the transformation of a rural economy. A common question is whether agricultural policies can provide the impetus to move agriculture in developing economies from subsistence to commercial agriculture. Senegal’s Plan Sénégal Emergent (PSE) provides a data point in this discussion. Senegal and international donors invested in agricultural supply chains starting in 2012 to facilitate the emergence of commercial agriculture for peanuts, rice, and vegetables. This study focuses on these investments in the Senegal River Valley of northern Senegal. The empirical results presented in this study provide evidence that farms in the Senegal River Valley impacted by PSE have moved away from subsistence agriculture by planting more hectares in commercial crops.

Objectifs : Le but de cette étude était de déterminer la composition phytochimique et la teneur en grandes classes chimiques des tiges les plus utilisées comme bâtonnets frotte-dents chez les peul de Widou Thiengoli au Nord Ferlo (Sénégal). Méthodes et résultats : Des entretiens ouverts semi structurés ont permis de recueillir les plantes les plus utilisées. L’indice de fidélité renseigne sur la convergence des usages quant à l’emploi des plantes comme bâtonnets frotte-dent comparé aux autres pratiques cosmétiques. L’étude de la composition phytochimique des tiges a ciblé 8 classes chimiques. Les tanins et les saponines sont très fréquents ; les terpénoïdes et les leuco-anthocyanines presque inexistants. Un dosage des flavonoïdes, alcaloïdes et polyphénols, réalisé chez des extraits aqueux, a porté sur 12 plantes. Les meilleures teneurs en polyphénols et alcaloïdes sont recueillies chez Anogeissus leiocarpa, et la meilleure en flavonoïdes chez Commiphora africana. Conclusion et applicabilité des résultats : Ces résultats permettent de sélectionner à travers la composition phytochimique des plantes, les espèces présentant de potentielles activités antimicrobiennes, car renfermant des composés phytochimique doués de fonctions germicides, au- delà de la fonction mécanique connue des bâtonnets dans l’élimination de la plaque dentaire.

Methods and results: Open semi-structured interviews made it possible to collect data on the most used plants. The fidelity index provides information on the convergence of uses regarding the use of plants as toothbrushes compared to other cosmetic practices. The study of the phytochemical composition of the stems targeted 8 chemical classes. Tannins and saponins were very common; almost non- existent were the terpenoids and leuco-anthocyanins. An assay of flavonoids, alkaloids and polypnenols, in aqueous extracts, was carried out on 12 plants. The best contents of polyphenols and alkaloids were obtained from Anogeissus leiocarpa, and the best of flavonoids from Commiphora africana. Conclusion and applicability of the results: These results make it possible to select, through the phytochemical composition of plants, the species exhibiting potential antimicrobial activities, because they contain phytochemical compounds endowed with germicidal functions, beyond the known mechanical function of the rods in the plan removal of dental plaque. Keywords: Toothbrush sticks, Phytochemical determination, Ethnobotany, Téssékéré, North Ferlo, and Senegal.

The umbilical hernia is a well-known pathology even though, its strangulation has been subject to much controversy. The aim of this work is to report our experience in the management of strangulated hernia of the child at the Ziguinchor regional hospital and to compare our results with those of the literature through a retrospective and descriptive study over a four years period. During the study period 24 patients with high male predominance were received. The mean age of the patients was 2.1 years. 45% of patients had a chronic cough. The average time for consultation was 27.6 hours. A notion of abdominal abrupt was found in 45% of the cases. The vast majority of patients arrived at the hospital during the dry season. Abdominal pain and vomiting were the main symptoms. An occlusive syndrome was present in about half of the patients. The diameter of the collar of the hernia varied between 1.5 and 2.5 cm and no intestinal necrosis was found during exploration. The surgery was simple in the majority of cases. Umbilical hernia is a reality in under-developed environment some factors promotes its complications.

The study of the Pteridophyte flora of some wetlands in the Kedougou region of the Senegal Republic is the subject of this study. This analysis is based on the herbarium material of the pteridological flora harvested in this region and preserved in the herbaria of various institutions of IFAN, Dakar and Paris (P) also on the bibliographic data. This leads to a field mission to re-evaluate pteridophyte flora in this region. The results obtained show that the diversity of pteridophyte in the region of Kedougou is 11 species except for the very young species whose identification could not be made. These species grouped into 7 genera belong to 5 families of which the best represented are the Pteridaceae with 4 species. All the harvested and identified species were encountered in the Herbarium visited. Thus, in order to facilitate access to their identification, it is necessary to propose the tool which means that the document conforms to the identification key on the paper and the vegetative characters have been favored. Most of the pteridophyte were harvested at the Dindefelo cascade with an abundance of the species Adiantum philippense L. which is a species with large distribution because it is found in almost all the prospected places. All of these species are restricted to wetlands and shaded areas with occupation of all habitats (terrestrial, aquatic, saxicolous and epiphytic).

Full textAbstract:
ABSTRACTBased on evidence from a French-Wolof phrase book published in Senegal in 1864, this article makes the case that urban Wolof, a variety of the language characterized by significant lexical borrowing from French, is a much older variety than scholars have generally claimed. Historical evidence suggests that urban Wolof emerged in the 18th and 19th centuries in the coastal island city of Saint-Louis du Sénégal, France's earliest African settlement and future capital of the colonial entity that would be known as French West Africa. The intimate nature of early contact between African and European populations and the later role played by the métis or mixed-race population of the island as linguistic brokers contributed to a unique, urban variety of Wolof that has important links to today's variety of urban Wolof spoken in Dakar and other cities throughout the country.

L’utilisation des pesticides dans l’agriculture engendre des résidus toxiques non négligeables sur les produits agricoles et sur les matrices environnementales. L’emploi frauduleux des pesticides non autorisés, le surdosage des produits actifs et leur utilisation abusive par les producteurs impactent sérieusement la santé des populations. L’objectif de cette étude est d’identifier les sources de contamination du chou à travers l’évaluation du niveau de contamination des matrices. Les échantillons de sols et d’eaux ont été prélevés conformément aux Directives de la FAO tandis que ceux du chou l’ont été en respectant la norme du Codex Alimentarius. Les résultats montrent que sur les 30 échantillons d’eau prélevés dans les puits, une seule contamination a été notée avec la Lambda-cyhalothrine à 3,93 μg/l. L’analyse du sol montre que 43,33% des échantillons ont été contaminés par les pesticides. L’analyse du chou montre que 63,3% des échantillons sont contaminés. La trifluraline constitue la substance active la plus fréquente, suivie du diméthoate et de l’heptachlore (POP). Ces produits ont été retrouvés à des seuils dépassant la LMR du Codex Alimentarius. L’eau et le sol ne sont pas des sources de contamination du chou. La contamination du chou est liée à l’utilisation des pesticides par les producteurs. En effet, les produits qui contaminent le chou n’ont pas été observés dans les matrices environnementales eau et sol. Le chou, très consommé au Sénégal est un légume fortement pollué qui devrait faire l’objet d’un suivi régulier.

English Title: Poor phytosanitary practice, the main source of cabbage contamination in Senegal
The use of pesticides in agriculture generates significant toxic residues on agricultural products and on environmental matrices. The fraudulent use of unauthorized pesticides, overdose active products and their abusive use by producers seriously impact the health of populations. The objective of this study is to identify cabbage contamination sources through the evaluation of the level of matrices contamination. The soil and water samples were collected in accordance with FAO guidelines while those of the cabbage were respecting the Codex Alimentarius standard. The results show that out of 30 water samples taken from the wells, only one contamination was noted with Lambda-cyhalothrin at 3.93 μg/l. Soil analysis shows that 43.33% of samples were contaminated by pesticides. The cabbage analysis shows that 63.3% of the samples were contaminated. The trifluralin is the most common active substance, followed by the dimethoate and the heptachlor (POPs). These products have been found at levels exceeding the Codex Alimentarius MRL. Water and soil are not sources of cabbage contamination. Cabbage contamination is related to the use of pesticides by farmers. In fact, the products that contaminate cabbage have not been observed in environmental matrices (water and soil). Cabbage, which is widely consumed in Senegal, is a highly polluted vegetable that should be monitored regularly. This study is an indispensable decision support tool for better pesticide management.Keywords: Cabbage, soil, water, pesticides, POPs, Africa.

This article shows how French doctors based in Saint-Louis-du-Sénégal, the capital of colonial Senegal, conceptualised the Senegambian region as a diseased environment and Africans as carriers of infectious agents. It explains how perceptions of the hot tropical climate, combined with outbreaks of epidemic diseases and seasonal allergies, were instrumental in the processes of urban transformation through hygienic measures such as waste removal, the closing of cemeteries, and the imposition of new building codes. The article also shows how the stigmatisation of Africans was implicated in the forced removal of the urban poor – firstly from the city centre, and later from the entire city-island. Colonial medical knowledge in Senegal was initially based on the miasma theory, however, germ theory was adopted in the aftermath of the 1900 yellow fever epidemic. Both theories, in relation with racialism, impacted the urban landscape in Saint-Louis, Senegal.

This article explores the ways in which French colonial authorities met the life and death challenge represented by the re-emergence of yellow fever epidemics in Saint-Louis-du-Sénégal at a time when physicians knew very little about the etiology, diagnosis, transmission and treatment of most infectious and parasitic diseases. The discussion focuses on changing strategies and policies designed to address yellow fever threats, the attitudes and priorities of the authorities, the limits of ‘colonial medicine’ and the responses of people affected by sanitary measures. The article argues that because of the ignorance of the etiology and epidemiology of yellow fever, policies were misdirected and did not achieve their primary goals. Even after the introduction of germ theory, the gap between medical thinking and practice persisted for another decade. The African urban working class and underclass were the first victims of this state of affairs. The article also examines the conflict between the interests of public health, commerce and privacy rights.

The French in West Africa remained deeply ambivalent in regard to applying naturalization policies to their African subjects. Applying a distinction between ‘citizenship’ and ‘nationality’, this article traces the history of French colonial policy from 1789 through decolonization in the 1950s. Apart from the originaires of the four communes of Senegal, who had ill-defined rights of French citizenship without ever being considered French nationals, naturalization policy in West Africa became so restrictive that no more than sixteen individuals were granted French citizenship each year between 1935 and 1949. This article uses dossiers of naturalization cases from French West Africa.

Logistic regression model is widely used in many studies to investigate the relationship between a binary response variable Y and a set of potential predictors X. The binary response may represent, for example, the occurrence of some outcome of interest (Y=1 if the outcome occurred and Y=0 otherwise). When the dependent variable Y represents a rare event, the logistic regression model shows relevant drawbacks. In order to overcome these drawbacks we propose the Generalized Extreme Value (GEV) regression model. In particularly, we suggest the quantile function of the GEV distribution as link function. Strokes are a serious pathology and a neurological emergency involving the vital prognosis and the functional prognosis. In Senegal, strokes account for more than 30% of hospitalizations and are responsible for nearly two thirds of mortality. In this work, we use the GVE regression model for binary data to determine the risk factors leading to stroke and to develop a predictive model of life-threatening outcomes in central Sénégal.

Les sécheresses successives, aggravées par les activités anthropiques et les effets du changement climatique, entrainent la disparition effrénée de plusieurs espèces végétales locales, adaptées selon les zones avec une importance sociale et économique avérée pour nos campagnes. Si le rythme de disparition noté n’est pas stoppé ou freiné, il s’en suivra la perte de l’essentiel de nos ressources végétales céréalières, fourragères et forestières locales. Certes, la recherche agricole s’évertue à trouver des solutions pour disposer de nouvelles variétés végétales adaptées. Mais, ce n’est pas toujours le cas pour les espèces fourragères. Ainsi, dans le cadre des activités de recensement et de collecte multi-spécifiques de ressources phytogénétiques pour l’alimentaire et l’agriculture, une synthèse spécifique a été consacrée au ressources fourragères des zones visitées. L’objectif visé est de recensé les ressources fourragères (naturelles ou cultivées) disponibles et leur méthode de gestion. Il ressort que les méthodes et le niveau d’exploitation des ressources fourragères naturelles et des résidus de récolte diffèrent d’une zone à l’autre. Le parcours naturel plus ou moins bien fourni dans les régions sud et est, constitue la principale ressource alimentaire des animaux au niveau de toute la zone d’étude. Les résidus de récolte bien qu’abondants et variés, ont peu d’intérêt chez les éleveurs du sud du Sénégal où la diversité qui est l’indice de qualité et le volume des pâturages sur le parcours naturel sont abondants. Certes, l’inventaire des espèces fourragères ne peut se faire selon la même méthodologie que celle des espèces agricoles et maraîchères. Mais, la photographie obtenue devrait servir de guide à un recensement des espèces fourragères herbacées et ligneuses les plus consommées sur le parcours naturel, tout en étudiant les méthodes de conservation et de production des espèces recensées afin, de dégager les meilleures méthodes de gestion et d’utilisation durable.Mots clés : Ressources fourragères, régions sud et est du Sénégal, ligneux et herbacés, résidus de culture.
English Title: Forage resources, feeding and grazing in the South, and East of SenegalSuccessive droughts, aggravated by anthropogenic activities and the effects of climate change, lead to frantic disappearance of several local plant species, adapted according to the areas, and with proven social and economic importance for our countryside. If the rate of disappearance noted, is not stopped or slowed, it will follow the loss of most of our local grain, fodder and forest plant resources. Certainly, agricultural research is struggling to find solutions to have new adapted plant varieties; this is not always the case for forage species. Thus, within the framework of multi-specific census and collection activities of plant genetic resources for food and agriculture, a specific summary was devoted to the fodder resources of the areas visited. The objective is to identify the fodder resources (natural or cultivated) available and their management method. It appears that the methods and level of exploitation of natural fodder resources and crop residues differ from one area to another. The more or less well supplied natural route in the south and east regions constitutes the main food resource for animals throughout the study area. Crop residues, although abundant and varied, are of little interest to breeders in the south of Senegal where the diversity which is the quality index and the volume of pastures on the natural range are abundant. Of course, the inventory of fodder species cannot be done according to the same methodology as that of agricultural and market garden species. However, the photograph obtained should serve as a guide for a census of herbaceous and ligneous fodder species most consumed by animals on natural route, while studying the methods of conservation and production of the listed species; in order to identify the best methods of management and sustainable use.Keywords: Fodder resources, southern and eastern regions of Senegal, ligneous and herbaceous plants, crop residues.

Mr. MD is a 72-years-old man, admitted for spontaneous, permanent, crushing type pain on the pelvis above the right hip evolving for two years, without night or morning stiffness but increasing with hearing loss, temporal and parietal headache. Physical examination showed a painful hip in active and passive mobilization. Pressure on iliac spines and lower lumbar and sacrococcygeal bones was painful. The patient showed no inflammatory syndrome. Serum calcium was normal. We noted an isolated increase in alkaline phosphatase levels to 401 IU/l. Radiographs showed bilateral heterogeneous sclerosis of the iliac bone with thickening lines and and almost disappearance of the right hip joint space. There was a marked thickening of the cortex on the femoral proximal third and thickening of the cranial vault. MRI showed cortical thickening of the right pelvic bone, a T1 hyper signal, and an intermediate T2 signal with fat/sat. This was pathognomonic of Paget's disease. The second patient is a 72-year-old man with no history, having intense pain on the right side of the lower limb. Physical examination showed no musculoskeletal deformity, but pain on palpation and mobilization of the right hip. Serum alkaline phosphatase (ALP) was raised to 4 times the normal range. Radiography showed cortical thickening of the ischial pubic branch, a heterogeneous sclerosis gypsy moth of the iliac wing, a steady narrowing of the femoral hip-spaced lines and thickening of the iliac ischial pubic. This aspect is pathognomonic of Paget’s disease, the patient underwent treatment with zoledronic acid intravenously at 5 mg. The outcome was favorable up to 10 months with reduced pain (VAS = 2/10) and normal PAL.

Ce travail a pour objectif principal d’évaluer l’importance des espèces ligneuses dans le bassin arachidier. Une enquête ethnobotanique a été réalisée sur la base d’un questionnaire portant sur les espèces fourragères utiles, leurs princiapaux usages, les modes d’exploitations et les parties utilisées. L’enquête a révélé que 82,14% des espèces ligneuses inventoriées sont considérées comme fourragères. Il s’agit notamment de Adansonia digitata, Cordyla pinnata, Faidherbia albida, Ficus capensis, Ziziphus mauritiana et Sterculia setigera. Ce constat montre l’importance de la richesse spécifique des champs où se trouvent toutes ces espèces.

The study is carried out in the community routes of the department of Kaffrine. This zone constitutes an essential axis of transhumance during the dry season of ruminants. Its woody vegetation contributes to the feeding of the livestock but is under enormous pressure of various kinds. The main objective of this work is to assess the importance of woody species in the groundnut basin. An ethnobotanical survey was carried out on the basis of a questionnaire relating to useful fodder species, their main uses, the modes of exploitation and the parts used. The survey revealed that 82.14% of the woody species inventoried are considered as fodder. These include Adansonia digitata, Cordyla pinnata, Faidherbia albida, Ficus capensis, Ziziphus mauritiana and Sterculia setigera. This observation shows the importance of the specific richness of the fields where all these species are found. The dry season is the period during which woody trees are more exploited by agro-pastoralists. Other respondents use these woody fodder for human consumption, pharmacopoeia, handicrafts, lumber, firewood, etc., which shows great pressure on these resources. The promotion of assisted natural regeneration, the production of fodder crops (making farmers aware of the benefits of these crops), moderate prunings limited, for example, to a quarter of the crown of fodder trees, could help to reduce the pressures exerted on woody plants. the most popular.Keywords: Ethnobotanical survey, forest, fields, pressure.

In the village soil of Thiobon in lower Casamance (southern Senegal), site being established as Marine Protected Area (MPA), the main activities of the population (rice growing, harvesting of fish products, salt production, …), happens in mangrove zone. These mobilize the population for several months in the year. This mangrove ecosystem, vulnerable and fragile, has undergone profound changes since the 1960s under the combined actions of rainfull variability and main. This study proposes to analyze the spatio-temporal dynamics of Thiobon mangrove. The method used is based on the processing and analysis of satellite data (Landsat imagery acquired in 1972, 1986, 2000 and 2017), rainfall data (1960 to 2017), and on the perception of populations of change in their terroir (field investigation). Map results indicate an overall decline on 52% in mangrove area in tanne during drought years (1970 to the late 1990s). During 2000–2017, characterized by the almost normal return of the rainfall and activities of reforestation done by the local population, about 69% of the mangrove areas lost between 1972 and 2000 regenerated. This dynamic is the result of external and internal forces exerted on this ecosystem and evolve since the early 1970s.

Pressure-driven membrane processes such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) are increasingly used to produce clean water for a broad range of domestic and industrial applications. This article outlines some key features of these membrane-based technologies and describes how they can be adapted to supply safe drinking water in remote communities and rural regions from the developing world. Three case studies are reported in Asia (Thailand) and Africa (Sénégal and Mali) where we investigate the feasibility of removing microorganisms and some dissolved pollutants from water with commercial pressure-driven filtration pilots. The convincing success of the Thailand study established that Pall transportable MF/UF units could help local residents meet their demand in high quality water. This case study provided some rationale for testing a similar concept in West Africa. Given the technological efficacy, robustness and modularity of these membrane systems, we see them as innovative tools for implementing a cost-effective and sustainable strategy to stop the emergence of water borne and vector borne infectious diseases not only in the developing world but also in regions severely affected by natural disasters.

Les causes les plus importantes de variation des effectifs des poules dans un ménage ont été la consommation (25,5%), les ventes (31,22%) et les pertes (38,68%). Les pertes ont été causées en grande partie par les rapaces (21,61%) et les chats (65,80%). Quant aux circonstances de consommation des poules, les plus importantes ont été les festivités religieuses (37,97%) et de fin d’année (26,06%) ainsi que les consommations domestiques (14,34%) ou d’accueil d’un hôte (11,52%). Les oeufs pondus (10,2) sont presque tous couvés (10,1). Les taux d’éclosion et de mortalité des poussins ont été de 81,36% et de 47,11%. Le rapport profit sur investissement, consommations internes du ménage incluses, a été de 4,05. Les consommations moyennes annuelles d’oeufs et de poules par ménage ont été de 56,7 oeufs et de 48 poules dans un ménage de taille moyenne de 7 personnes. Il ressort de cette étude que l’aviculture familiale constitue un moyen d’amélioration de la sécurité alimentaire et d’atténuation de la pauvreté. Des recherches doivent être faites pour améliorer la protection des poussins, l’alimentation et la santé des oiseaux.Mots clés : Aviculture familiale, sécurité alimentaire, lutte contre la pauvreté, socio-économie, Sénégal. English Title: Socio-economic importance of family poultry in SenegalA one-year longitudinal survey was carried out in 45 poultry farms in Salémata Department (Senegal) to show the contribution of family poultry to poverty alleviation and food security in a household. The results showed that chicken numbers increased from 17.1 to 23.4 hens. The most important causes of variation in hen numbers in a household were consumption (25.5%), losses (38.68%) and sales (31.22% hens). The most frequent causes of mortality were predators (Raptors: 21.61% and cats: 65.80%). The most important circumstances of consumptions were religious holidays (37.97%) and year-end (26.06%), the household (14.34%) or to welcome a host (11.52%). The eggs laid (10.2) are almost all incubated (10.1). The hatching rate and chicks' mortality were 81.36% and 47.11%, respectively. The return (profit/investment) with family consumption was 4.05. The average annual consumption of eggs and chickens per household was 56.7 eggs and 48 chickens in a household size of 7 people. This study shows that family poultry constitute an improving food security and poverty alleviation. Researches are to be done to improve chick protection, feeding and bird health.Keywords: Family poultry, Senegal, socio-economy, food security, poverty alleviation.

La qualité de l’eau de boisson conditionnée en sachet, vendue sous différentes marques dans les marchés de Dakar a été étudiée. Un total de 60 échantillons d’eau conditionnée dans des sachets sous 15 différentes marques a été prélevé de façon aléatoire dans les 5 différents marchés de Dakar pour déterminer la qualité physicochimique et microbiologique. Les résultats ont montré que la qualité physicochimique des eaux conditionnées en sachet est conforme à la norme réglementaire Norme NF EN ISO 19458 en la matière. Cependant, en ce qui concerne la qualité microbiologique, 83% des échantillons ont été contaminés avec une forte charge de la flore mésophile aérobie totale supérieure à celle de la norme NF EN ISO 19458 et 15% des échantillons sont vigoureusement contaminés par les coliformes totaux. Cependant, aucune présence de salmonelle n’est enregistrée dans les échantillons étudiés. Malgré tout, la population de Dakar qui utilise cet eau s’expose à des risques sanitaires. Il convient au service d’hygiène de sensibiliser et de contrôler l’activité de la vente de l’eau conditionnée en sachet.
The quality of drinking water packaged in plastic bags through different brands sold in Dakar markets has been studied. 60 samples packaged through 15 different brands were taken randomly from the 5 different markets to determine their physico-chemical and microbiological quality. The results showed that physicochemical quality complies with the standards in this area. However, with regard to microbiological quality, 83% of the samples were contaminated at a high load with total viable counts, higher than the standard and 15% of the samples are highly contaminated with total coliforms. Meanwhile, there is no salmonella contamination was recorded in the samples studied. As a result, the population of Dakar who relies to this drinking water supply is exposed to health risks. The hygiene service should raise awareness and monitor the activity of selling drinking water.

Abstract. This letter presents some night-time observations of neutral wind variations at F2 layer levels near the dip equator, measured by the Fabry-Perot interferometer set up in 1994 at Korhogo (Ivory Coast, geographic latitude 9.25°N, longitude 355°E, dip latitude –2.5°). Our instrument uses the 630 nm (O1D) line to determine radial Doppler velocities of the oxygen atoms between 200 and 400 km altitude. First results for November 1994 to March 1995 reveal persistent eastward flows, and frequent intervals of southward winds of larger than 50 ms–1 velocity. Compared with the simultaneous ionospheric patterns deduced from the three West African equatorial ionosondes at Korhogo, Ouagadougou (Burkina-Faso, dip latitude +1.5°) and Dakar (Sénégal, dip latitude +5°), they illustrate various impacts of the thermospheric winds on F2 layer density: (1) on the mesoscale evolution (a few 103 km and a few 100 minutes scales) and (2) on local fluctuations (hundreds of km and tens of minutes characteristic times). We report on these fluctuations and discuss the opportunity to improve the time-resolution of the Fabry-Perot interferometer at Korhogo.Key words.

Full textAbstract:
Maize plays a socio-economic role in Senegal. However, it is considerably damaged by Sitophilus Zeamais, a beetle of the Curculionidae. Areas likely to favor the survival or extinction of Sitophilus zeamais can be identified because genetic diversity influences the adaptability of the individual. Our study aims to highlight a possible variation and structuring of Sitophilus zeamais according to five agroecological zones (AEZ) in Senegal, namely Nord Bassin Arachidier (NBA), Sud Bassin Arachidier (SBA), Sénégal Oriental Haute Casamance (SOHC), Basse Moyenne Casamance (BMC) and Zone Sylvo-Pastorale (ZSP). The purpose of this study is to reduce crop losses by recommending to farmers peas where the insect is reluctant to survive. So far, genetic studies on this insect have traced its phylogeny and its geographical distribution in Africa in general. Senegal has never been specifically studied. To achieve this goal, 89 individuals were captured in the 5 zones. The exploitation of the cytochrome B gene corresponding to these individuals revealed a high genetic diversity in the NBA, SBA, and SOHC and low in BMC and ZSP, but also a genetic structuring of the insect according to agroecological zones. Thus, the agroecological zones of the NBA, the SBA and the SOHC are favorable to its survival, while those of the BMC and the ZSP limit its expansion.

Full textAbstract:
The shared reading of books is one of the activities that most contributes to the development of young children's language (JUSTICE; SOFKA, 2010; SÉNÉCHAL, 2015; EVANS; SAINT-AUBIN, 2005; SÉNÉCHAL; LEFEVRE, 2002) and has effects in the acquisition of the written language registers (BUS et al., 1995). However, the effects of this contribution depend on how the adult interacts and encourages the child's participation in the discussion and reflection beyond the text. Young children who actively participate in adult-led shared reading of books, which interact with them through questions, word-labeling, and referents, have greater gains in vocabulary than children who passively hear the book reading (SÉNÉCHAL et al., 1995). In addition, the use of questions plays a key role in directing attention and maintaining the child's participation in the activity of shared reading. The purpose of this study is to (1) determine how often preschool teachers ask questions during shared reading of books with their students, and (2) identify the types of questions that teachers asked related to basic vs. complex questions. A total of nine teachers and their students aged 3 to 5 years, from a city in the interior of Rio Grande do Sul, Brazil, participated in the study. Two shared reading sessions of each teacher (n = 18) were recorded on video, transcribed and coded using an adapted version of the Systematic Assessment of Book Reading-Transcript Coding Version 2.1 (ZUCKER et al., 2017). The results show that during the eighteen shared reading sessions, teachers compiled a total of 329 questions, classified into two categories: basic questions and complex questions. From the total, the basic ones had a higher frequency (n = 285) and complex questions were formulated less frequently (n = 44). The results of this research are in line with other studies (PENTIMONTI et al., 2018; BECK; MCKEOWN, 2001; GIROLAMETTO et al., 2000) that show that teachers usually ask basic questions more frequently when compared to complex questions. Therefore, we emphasize the importance of call teachers attention to the value of shared reading, mediated by an interaction that favors the formulation of questions, seeking to expand the proportion of complex questions, given the influence that this type of activity has on the cognitive and linguistic development of children.

L’objectif de cette étude était de collecter, trier et étudier la diversité phénotypique des accessions de maïs de décrue sur la base de quelques variables sélectionnées, parmi les descripteurs du maïs. Cent soixante-deux (162) accessions de maïs de décrue collectées dans la haute et moyenne vallée du fleuve Sénégal ont été ainsi triées et évaluées au plan morphologique. Parmi ces 162 accessions, 64,81% sont collectées au niveau de la haute vallée et 35,19 % dans la moyenne vallée. En se basant sur trois caractères morphologiques du maïs, (couleurs des grains, texture des grains et couleur de la rafle), le tri de cette collection a montré une très grande variabilité en morphotypes (15), avec la dominance du morphotype Jaune-Corné-Blanc (J-C-B) dans la collection avec un effectif (85/162). Les morphotypes avérés très rares ne dépassent pas l’effectif 1 dans la collection. La caractérisation sur épis de ces morphotypes en fonction de certains caractères (poids de l’épi et le poids de 100 graines, longueur de l’épi,…), liés au rendement a montré une diversité phénotypique très importante. En effet, le poids de l’épi varie de 63,03g pour les morphotypes à petits épis à 290 g pour les morphotypes à gros épis de même que pour la longueur de l’épi qui varie de 10,5 cm à 26 cm. Cette diversité offre une grande possibilité de choix des géniteurs pour la création de variétés améliorées de maïs ayant un potentiel de rendement élevé et adaptées à différentes zones agro-écologiques de la vallée du fleuve Sénégal. ABSTRACT The objective of this study was to collect, sort and study the phenotypic diversity of flood recession maize accessions based on a few selected variables, among the maize descriptors. One hundred and sixty-two (162) flood recession maize accessions collected in the high and medium valley of the Senegal River were thus sorted and evaluated morphologically.Among these 162 accessions, 64.81% are collected in the upper valley and 35.18% in the middle valley. Based on three morphological characteristics of the maize (grain colors, texture and color of the stalk), the sorting of this collection showed a great variability in morphotypes (15), with the dominance of the morphotype Yellow-Corné-Blanc (JCB) in the collection with a strength (85/162). The morphotypes found to bevery rare do not exceed the number 1 in the collection. Characterization on the ears of these morphotypes according to some characteristics (weight of the ear and the weight of 100 g, length of the ear), related to the yield showed a very important phenotypic diversity. In fact, the weight of the ear varies from 63.03 g for short-eared morphotypes to 290 g for coarse-cut morphotypes as well as for spike length ranging from 10.5 cm to 26 cm. This diversity offers a great opportunity for brood stock selection for the creation of improved maize varieties with high yield potential and adapted to different agro-ecological zones of the Senegal River Valley.

Full textAbstract:
This work aims at examining the potential impacts of vegetation change (reforestation) of the Sahel-Sahara interface on the intra-seasonal and interannual variability of the rainfall and surface temperature over Senegal using the RegCM4 model. Two runs were performed from 1990 to 2009 with a spatial resolution of 50 km (0.44 °): the standard version of the RegCM4 model (control version) and the reforested one (named RegCM4_REFORESTATION). The impact of the reforestation is to decrease the surface temperature over Senegal in summer (JJAS). This decrease could be partly due to a decrease of the sensible heat flux over the southern and central Senegal and a strong increase of the latent heat flux. The reforestation also tends to increase the rainfall over the whole country and particularly in the Southwest. This rainfall increase which can also create an evaporative cooling, is consistent with the decrease of the surface temperature. The analysis of the annual cycle over three domains of Senegal shows that the reforestation tends to strengthen the low-levels humidity of the atmosphere from January to December especially during the summer period in the North and in the center of the country. The surface temperature presents two maxima in April-May and October-November and a minimum during the summer. The reforestation has a cooling impact during the whole year (particularly in the summer) and over the center and the northern part of Senegal. At the interannual timescale, the reforestation modifies significantly the rainfall by generally increasing it. However, there are years in which this trend is not respected and this translates into a weak correlation coefficient in the South of the country. This rainfall increase may translates into extreme hydroclimatic events such as floods. This work can be considered as a support for the Senegalese policymakers for the better planning of the management of adverse potential effects (such as floods, drought, heat waves, etc) of the Sahel-Sahara greening effort.

Full textAbstract:
This present study was conducted to determine the structure and characteristics of the adventitious flora of the agricultural farm of Gaston Berger University (UGB) located in Saint Louis, Senegal. A species inventory was carried out using the "tour de champ" technique which consists of going through a plot in different directions and recording all the species present in the studied area. The inventoried flora is composed of 149 species distributed among 90 genera belonging to 30 families which are dominated by the Poaceae (18.8%) and the Fabaceae (15.4%). This flora is also characterized by the predominance of the therophytes and the chamephytes which represent 79.9% and 10.7% of recorded species, respectively. From a chorologic standpoint, pantropical (29.5%) and African (28.2%) species account for more than half of the species (57.7%). The quantitative analysis of this flora reveals that rare or accidental species are more represented (52%) followed by frequent species (16%) and secondary species (15%).

Objective: To assess the effect of vegetation cover on soil macrofauna, a study focused on the diversity of soil macrofauna inside and outside reforestation plots of the Great Green Wall in Senegal was carried out. Methodology: The sampling of macrofauna was performed according to the method recommended by the TSBF network (Tropical Soil Biology and Fertility). It involves isolating 10 ground plots along a transect of 50 meters chosen at random in each plot and outside of each plot. The macrofauna was sampled between February and July 2016 during the dry season Results: The results show, in order of importance Hymenoptera, Isoptera, Coleoptera, the Spiders, the isopods and springtails are the taxonomic groups of the study area. The density of each of these taxa is larger inside and outside of the plots. The vertical distribution of macrofauna shows that the 0-10 cm layer is more densely populated than the deeper layers. Conclusion: This study showed a low diversity of soil macrofauna in the area. It also shows that the vegetation cover affects the density of the macrofauna.
