The North-East region (Bounkani) of Côte d'Ivoire is the least watered region of the country with an average annual rainfall of 945 mm. The rainfall deficits observed in Côte d'Ivoire since 1970s could constitute a real threat to the environment and to water resources in general, and to dam lakes in particular. The main aim of this study was to follow the evolution of the dam lakes in the region over the years, i.e,(1986, 2002 and 2017) with reference to their spatial distribution (their densities and their limnological ratios). The approach adopted consisted of mapping and monitoring through remote sensing technology which involves processing satellite images for automatic extraction of these agropastoral structures on the various images. The results showed that these dam lakes were unevenly distributed both at the level of the departments and the watersheds, with 73.43% in the Black Volta and 28.57% in the Comoé. The density was higher in Doropo and varied from one department to another from 1986 to 2017, for the department of Bouna, it ranged from 9.34.10-4 to 3.74.10-3 per km2. The departments of Doropo and Tehini showed 1.51.10-3 to 1.01.10-2 per km2 and 1.05.10-3 to 4.53.10-3 per km2 respectively. Nassian department displayed a value of 1.42.10-3 per km2 and remained constant from 2002 to 2017. Like the density, Doropo Department had the highest limnological ratio which changes from 7.09.10-5 to 2.71.10-4 per km2 over the same period. The mapping of these agropastoral structures showed 18 agropastoral structures where 57 (28.07%) were functional or even contained water in the dry season in the region in 2017 including 2 in Nassian; 4 in Tehini; 9 in Doropo and 3 in Bouna.

Based on an inquiry on the ground and geostatistics prossessing, this task analyses the problematic of aridity and the perception done by the peasant populations of the ‘’ North -East quarter’’ region of IVORY COAST. We come to know from these analyses that the dryness is a reality in this part of IVORY COAST. Indeed, starting with the indexes of NICHOLSON and MC KEE that is the test of PETTIT and the monthly climatic balance, agricultural and meteorological dryness have been determined to all the studied stations. Mainly the meteorological dryness is much more intensive in this sector of BOUNA and DABAKALA. As to agricultural dryness, it has been heavier in BOUAKE,KATIOLA, DABAKALA and BOUNA respectively. The test of FISHER has justified the variation of the dryness apprehension in the space. Thus, the dryness can be grasped by different ways (four ways) according to the inquired places. However, the peasant populations cannot distinguish the differences between meteorological and agricultural dryness clearly.

The present study was done in seven markets of Abobo (Côte d’Ivoire) for inventory vegetal antidiarrheal resources. Ethnobotanical information obtained beside 44 traditional herbalists, based on interviews, show that 18 plants species are used to cure to diarrhoea. They are belonging to 17 genera and 11 families. The best represented families were: Euphorbiaceae. Three species commonly cited by healers were: Psidium guajava, Alchornea cordifolia and Euphorbia hirta. Various plant organs are used for the preparation of drug recipes. Leaves are the most used. These receipts which are mainly multispecific require different preparation methods (decoction, soaking and kneading). Most remedies are prepared as a decoction. Administration was essentially oral. This study constitutes a source of very precious information for subsequent researches for the domains of the phytochemistry and pharmacology in order to search for new natural substance.

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.

AbstractBackgroundDiabetes autoantibodies are indispensable markers of diabetes classification.Objectiveto research autoantibodies anti-GAD and anti-IA2 in type 1A diabetics (T1D) aged 5 to 21 years, and to follow the progression of these autoantibodies in T1D patients, in Côte d’Ivoire.MethodsThe study population composed of 28 T1D patients, aged 5 to 21 years. T1D were followed up in two diabetes care centers in Abidjan district, Endocrinology departments of U.H.C of Yopougon and Treichville. Anti-GAD and anti-IA2 autoantibodies were researched by ELISA.Resultsanti-GAD and anti-IA2 were present in T1D and their siblings. After 2 years of diabetes, the titer of the anti-GAD autoantibodies increased to the mean value of 677.10 ± 353.20 IU / ml. Then, a fall of the anti-GAD autoantibodies until the cancellation was observed from the 8th to the 9th with values of 117 IU / ml to 10.14 IU / ml. Anti-IA2 autoantibodies fall at 9th year of diabetes with a value of 55.10 IU / ml.Conclusionanti-GAD and anti-IA2 autoantibodies persist after 9 years of diabetes, causing total destruction over time of the pancreatic β-cell mass in patients from Côte d’Ivoire, leading them to the death.
