Bibliographic Review of Aquatric Systems and their Relevance to the Ivory Coast, a Sub-Saharan African Country

Through a review of aquaponic techniques, the present work highlights the interest aroused by this practice in the world as well as different modes of exploitation. Aquaponics is defined as a coupling between a recirculated aquaculture compartment and an aboveground crop compartment. Since two decades, it has been the subject of a significant economic activity in Canada, the USA, Australia and induces numerous research activities. This system is subdivided into three (3) major techniques which are the culture techniques on bed of inert substrates, on nutritive film and that of rafts. Aquaponics is the subject of profitable industrial economic activity on both large and small scale in the USA and Canada. Given the benefits of low water consumption, the non-use of fertilizers and pesticides, aquaponics is unquestionably according to researchers and users, the system capable of revolutionizing livestock farming and agriculture around the world. Côte d'Ivoire is suffering not only from the consequences of climate change but also from rapid urbanization, with the consequent change in water resources. Aquaponics deserves to be mastered then popularized in this country, to help produce fish and plants of better quality while avoiding the waste of water caused by traditional livestock systems

Influence de la taille des vitroplants et du type d’explant sur la réponse à la callogenèse chez le cotonnier (Gossypium hirsutum L.) cultivé en Côte d’Ivoire

L’aptitude à la callogenèse chez le cotonnier a été estimée par le taux d’induction et le poids sec des cals en fonction de la source de l’explant et de la taille des plantules. Le taux d’induction des cals augmente avec la taille des plantules alors que le poids sec des cals ; résultat de la croissance des cals, évolue en sens contraire. L’hypocotyle permet d’induire une bonne callogenèse suivi de la racine et du cotylédon quelle que soit la taille des plantules. Les plantules de petite taille ont une bonne aptitude à la  callogenèse pour les explants hypocotyles et racines alors que pour les explants cotylédons, ce sont les plantules de grande taille qui favorisent l’induction des cals.Mots clés: Cal, explant, cotonnier, <i>Gossypium hirsutum</i>, vitroplants

Dynamiques Socio-Economiques de l’Adoption de la Culture de l’Anacarde en Milieu Rural Ivoirien : Cas de la Sous-Préfecture de Languibonou

Résumé - La culture de l’anacarde en Côte d’Ivoire occupe une place importante dans l’économie rurale. Depuis les politiques de valorisation de cette culture, elle se présente comme la culture traditionnelle pour les populations du centre et du nord à la substitution du vivrier et du maraîcher. Tout en privilégiant l’approche mixte, l’étude a mobilisé la recherche documentaire, un questionnaire et un guide d’entretien pour la collecte des données sur le terrain. La théorie du changement social et celle de l’acteur stratégique ont servi de fondement théorique à l’analyse des données. Comme résultat, on retient que malgré les contraintes du marché liées aux fluctuations des prix bord-champ, l’anacarde fournit des revenus importants aux paysans et contribue au développement local à travers la création d’emplois directs et indirects. Face aux contraintes du marché, ils développent des stratégies d’extension des surfaces dans le but d’accroître leur production agricole. Celles-ci servent de stratégie de captation du foncier et constitue une menace pour l’économie alimentaire.Abstract – the cultivation of cashews in the Ivory Coast occupies an important place in the rural economy. Since the promotion policies of this culture, it presents itself as the traditional culture for the populations of the center and north in the substitution of the food crop and the market gardener. While favoring the mixed approach, the study mobilized documentary research, a questionnaire and an interview guide for collecting data in the field.the theory of social change and that of strategic actor served as the theoretical basis for the analysis of the data. As a result, we note that despite the market constraints linked to price fluctuations on the field, the cashew nut provides significant income to farmers and contributes to local development through the creation of direct and indirect jobs. Faced with market constraints, they are developing land extension strategies in order to increase their agricultural production. These serve as a land capture strategy and pose a threat to the food economy.Keywords – Agriculture, Cashew, Peasant, Economic Change,  Local developmen

Characterization of the rainy seasons in context of climate change : Case of Sassandra watershed (Côte d’Ivoire)

The impacts of climate change are a reality nowadays and deserve to be studied at various scales in order to adapt better. It is in this context that this study has been treated and aims to characterize the rainy season in a context of climatic changes.Using daily rainfall data and the agronomic method of Sivakumar, the start and end dates and also the durations of the rainy seasons have been determined. This method makes it possible to highlight the temporal and sptial variability of these climatic parameters of the rainy seasons in the Sassandra watershed in a context of climate change.The results showed a late start and an early cessation of the rainy season after 1970. Indeed, the year 1970, represents the reference date of rainfall shortages in West Africa and Côte d'Ivoire in particular.               This has resulted in a reduction of about 30 to 35 days in the duration of the rainy season over the entire catchment area.Depending on climatic zones, the start and end dates of the rainy seasons have been determined. Indeed, the great rainy seasons start on average between 11 March and 15 May and end between 19 June and 11 November. Its duration is 62 to 101 days (equatorial climate), 188 days (Mountain climate) and 156 to 166 days (tropical transitional climate)

Le zouglou ou la variété musicale de pouvoirs de mots en Côte d’Ivoire

Le zouglou est une variété musicale qui, embellie par de puissants énoncés, se forge d’être unconseiller pour certains Ivoiriens et un avertisseur ou un critiqueur pour les autres. Lamusique qu’il distille dans des sonorités variées, humoristiques et pragmatiques puise sapuissance de réflexion, sa qualité et son fort caractère social dans des mots du patrimoinelinguistique ivoirien. Notre contribution se propose de mener une étude sociolinguistique desmots et syntagmes utilisés dans la chanson zouglou à l’effet de comprendre son impact sur lapopulation ivoirienne
