Political Turmoil

Following political turmoil and rising socio-economic difficulties, Côte d'Ivoire has been split into two since September 2002. The rebellion controls the northern part of the country and the main towns of Bouaké, Korhogo and Man, while the government controls the southern part with Abidjan, Yamoussoukro, Daloa and all the ports in the coastal area. At the beginning of the war, civil servants who were in place in the north of the country were called back to Abidjan to be redeployed in government-controlled areas. These included many teachers and education officials, but not all, as some of them chose to stay in the war-affected areas to continue their initial work. This article focuses specifically on governmental and local non-governmental initiatives related to education which were put in place at the onset of the crisis. What type(s) of education have been offered to the children in war-affected areas and to the displaced children in government-controlled areas? What have been the difficulties of organizing national examinations in war-affected areas? How have educational attainments been certified on both sides? The study covers the period 2002–06, and is based on document analysis, grey literature collected on site and interviews with key informants.

The work was conducted in the north of Cote d’Ivoire, central pivot cotton production savannah area, to make the diagnosis of soil fertility for cotton cropping. Cotton cropping, the mainstay of the savannah's economy, suffered from low productivity in relation to the soils chemical properties. Prior cultivation, soils samples were collected at a depth of 0 to 30 cm, collecting 32 simple samples to generate a complete sample. The samples were sent to the soil laboratory to measure the pH unities, CEC, nitrogen, phosphorus, potassium, calcium, magnesium, sodium, iron, zinc, copper and manganese contents. In order to facilitate the interpretation of analysis results, the nutrients critical level recommended for optimum production of cotton were used. Results showed that soils had pH ranging from 4.4 to 6.4. On the other hand, the need to add nitrogen, magnesium and phosphorus to the soils and to augment the low carbon, calcium and potassium content. There is the need to search for fertilizer formulations with nitrogen, magnesium phosphorus and calcium for the Cote d'Ivoire cotton belt.

Changements Climatiques

Les forêts classées du Nord de la Côte d’Ivoire connaissent un phénomène d’anthropisation accrue, notamment à la faveur de la crise sociopolitique de 2002 à 2011. A cela, s’ajoute l’effet des changements climatiques qui ont des conséquences sur la qualité de la biodiversité. Cette étude recherche, à travers l’analyse de paramètres floristiques et de la dynamique d’occupation du sol, des informations scientifiques fiables devant guider les orientations d’aménagement d’une forêt classée située dans la Région de la Bagoué, au Nord-Ouest du pays. L’étude de la dynamique de la couverture végétale de la Forêt classée est réalisée à travers une analyse diachronique des images satellitaires Landsat ETM de janvier 2002 et ETM + de mars 2016. L’appréciation des paramètres floristiques est basée sur l’interprétation des données d’inventaire floristique. Les résultats cartographiques montrent une régression des formations boisées passant de 81,75 % en 2002 à 71,19 % en 2016, soit un taux de régression annuel de 0,7 %. Concernant l’étude floristique, au total 281 espèces végétales, réparties entre 210 genres et rangées dans 71 familles, ont été inventoriées dans la forêt classée. Par cette flore, 18 espèces ont présenté un statut particulier, preuve de la valeur de conservation de cette formation végétale. Ce résultat pourrait servir pour la mise en place d’une forêt classée dans la Région de la Bagoué en Côte d’Ivoire. The classified forests of the north of Ivory Coast are experiencing an increased anthropization phenomenon, in particular thanks to the socio-political crisis from 2002 to 2011. In addition to this is the effect of climate change that has consequences on the quality of biodiversity. This paper focuses on the analysis of floristic parameters, the dynamics of land use, and reliable scientific information to guide the development orientations of a classified forest located in the Bagoué Region in the North-West. The study of the dynamics of the vegetation cover of the classified forest was carried out through a diachronic analysis of the Landsat ETM images of January 2002 and ETM + of March 2016. The appreciation of the floristic parameters is based on the interpretation of the floristic inventory data. The cartographic results show a regression of woodlands from 81.75% in 2002 to 71.19% in 2016, i.e., an annual rate of decline of 0.7%. Concerning the floristic study, a total of 281 plant species, divided between 210 genera and arranged in 71 families, were inventoried in the classified forest. Through this flora, 18 species presented a special status, which is a proof of the conservation value of this plant formation. This result could be used for the establishment of a classified forest in Bagoué Region of Côte d’Ivoire.

Aims: The study aimed to evaluate the nutritional and anti-nutritional factors composition of the Solanum torvum fruit. Place and Duration of Study: Department of Food Sciences and Technology, Biocatalysis and Bioprocessing laboratory of Nangui Abrogoua University (Côte d’Ivoire), between June 2019 and March 2020. Methodology: Proximate composition, mineral element profile and phytochemical composition of fresh and boiled S torvum berries were investigated. The S torvum fruit were harvested fresh. One part was cooked in boiling water for 25 min while the other part did not undergo any treatment. These two samples were dried in an oven at 45°C for 72 hours, ground and analyzed according to official analytical method. Results: The results indicated that the boiling caused the loss of nutrients except moisture, fibers and lipids. It was noted a significant reduction of nutrient and anti-nutrients content of berries after boiling. Boiled berries showed a higher energy value (57.07 Kcal) than fresh ones (53.12 Kcal). Despite the boiling, S torvum berries showed high levels of polyphenols (142.54 mg GAE/100g DW (dry weight)), carotenoids (12.96 mg βCE/100g DW), vitamin C (12.03 mg/100 g FW), fibers (6.88%) and ash (7.23%). Minerals analysis of S torvum berries indicated that it is rich in potassium (2046.77 mg/100 g DW), calcium (340.92 mg/100g DW), phosphorus (238.71 mg/100g DW) and magnesium (234.97 mg/100g DW) with high predicted bioavailability for calcium, magnesium and zinc. S torvum fruit contains also iron (7.97 mg/100g DW) and zinc (8.10 mg/100g DW) which are essential for organism. Conclusion: These data indicated that this Solanum torvum fruit consumed in East of Côte d’Ivoire could constitute a potential good source of nutrients for local population.

Cet article résume les données relatives à la pétrographie et aux compositions en éléments majeurs et en traces des granitoïdes du sillon de Korhogo. Le sillon de Korhogo est situé au Nord de la Côte d’Ivoire, dans le domaine birimien. Ce sillon qui constitue la branche Est du sillon de Boundiali-Korhogo est à cheval sur les régions du Poro et du Tchologo. La méthodologie employée a permis à l’issue des observations macroscopiques, de recueillir des échantillons pour les études microscopiques et géochimiques. Les études pétrographiques indiquent que les granitoïdes du sillon de Korhogo sont des granodiorites et granites. Ces granitoïdes ont été affectés par une intense altération pervasive et fissurale témoignant ainsi de l’intensité de l’altération hydrothermale dans le sillon de Korhogo. Ces roches ont été affectées par un le métamorphisme de faciès schiste vert. Les données géochimiques montrent que les granitoïdes sont calco-alcalins, potassiques, métalumineux à peralumineux et de Type « I ». Ces roches sont enrichies en LREE [Granodiorite ((La/Sm)N = 3,36 – 4,45 ; (Gd/Yb)N = 1,56 – 2,51 ; et (La/Yb)N = 7,29 – 20,92) ; Granite ((La/Sm)N = 4,51 - 4,69 ; (Gd/Yb)N = 1,00– 3,13 et (La/Yb)N = 7,63 - 26,53] et présentent des anomalies négatives à quasiment nulles en cérium [Granite (Ce/Ce*= 0,60 -0,92) ; Granodiorite (Ce/Ce* = 0,80 -1,01)]. Les anomalies en europium varient des granodiorites [(Eu/Eu* = 0,81 – 1,53)] aux granites [(Eu/Eu*= 0,90 - 1,11)]. Ces granitoïdes ont de faibles taux de TiO2 (<2 %). Les arachnogrammes des éléments en trace normalisés au manteau primitif sont généralement enrichis en LILE (Cs, Ba, Rb, K) associés à une anomalie négative en Nb-Ta. Les tendances géochimiques indiquent que les granitoïdes du sillon de Korhogo proviendraient d’un mélange crustal et mantellique et se seraient mis en place dans un contexte de subduction. This paper summarizes the data available on petrography and the concentrations of major and trace elements in granitoids from Korhogo greenstone belt province. The Korhogo greenstone belt is localed in the north of Côte d’Ivoire, in the birimian domain. This belt which constitutes the eastern branch of the Boundiali-Korhogo greenstone belt straddles the Poro and Tchologo areas. The methodology started by the macroscopic to microscopic observations then it continued to the geochemical studies. Petrographic studies indicate that the granitoids of Korhogo greenstone belt are granodiorites and granites. These granitoids were affected by intense pervasive and fissural alteration thus testifying the intensity of hydrothermal alteration in the Korhogo greenstone belt. These rocks were affected by regional greenschist facies. Geochemical datas show that the granitoids are calc-alkaline, potassic, metaluminous to peraluminous and “I” Type. These rocks are enriched in LREE [Granodiorite (La/Sm)N = 3,36 – 4,45 ; (Gd/Yb)N = 1,56 – 2,51 ; et (La/Yb)N = 7,29 – 20,92) ; Granite (La/Sm)N = 4,51 - 4,69 ; (Gd/Yb)N = 1,00 – 3,13 et (La/Yb)N = 7,63 - 26,53] and present negative to non-exixting cerium anomalies [Granite (Ce / Ce * = 0.60 -0.92); Granodiorite (Ce/Ce * = 0.80 -1.01)]. The europium anomalies vary from granodiorites [(Eu/Eu * = 0.81 - 1.53)] to granites [(Eu/ Eu * = 0.90 - 1.11)]. These granitoids have low levels of TiO2 (<2%). Primitive mantle normalized, trace element patterns show that granitoids have geochemical patterns characterized by enrichment in LILE (Cs, Ba, Rb, K) associated with negative Nb –Ta anomalies. Geochemical trends indicate that the granitoids of Korhogo greenstone belt originate from a crustal and mantle mixture and were set up in a context of subduction.
