Irvingia Gabonensis

Ce travail évalue l’importance socio-économique d’Irvingia gabonensis (Irvingiaceae) ou le manguier sauvage dans la région de l’Agnéby-Tiassa dans le sud de la Côte d’Ivoire. À cet effet, un inventaire de la population a été réalisé dans les zones agroforestières en particulier dans les cacaoyères afin de déterminer la perception de cette espèce par cinq groupes socio-culturels. Les différents usages et la rentabilité économique issue de la vente des amandes ont été également recherchés. Pour atteindre ces objectifs, la valeur d’usage ethnobotanique des différents organes, le taux de réponse des individus enquêtés et de la marge brute de commercialisation a été recherché. L’inventaire a permis de recenser seulement 26 pieds de I. gabonensis chez 35 paysans. Les travaux ont révélé deux usages principaux chez les Agnis, les Baoulés, les Groussis, les Malinkés et les Morés. Il s’agit de la consommation des amandes connue par 100% des enquêtés et de l’usage thérapeutique de l’écorce connue par seulement 10% de l’échantillon. Les investigations ont montré une marge brute de commercialisation moyenne de 27%. Des travaux complémentaires devront être réalisés pour valoriser d’avantage l’écorce et les feuilles. Aussi, nous préconisons le semis de graines ou le maintien de sauvageons dans les zones dégradées des cacaoyères en vue d’une gestion durable de cette ressource. SUMMARY This work assesses the socio-economic importance of Irvingia gabonensis (Irvingiaceae) or the wild mango tree in the Agnéby-Tiassa region in the south of the Ivory Coast. To this end, a population inventory was carried out in agroforestry areas, in particular in cocoa trees in order to determine the perception of this species by five socio-cultural groups. The different uses and the economic profitability resulting from the sale of almonds were also investigated. To achieve these objectives, the ethnobotanical use value of the different organs, the response rate of the individuals surveyed and the gross marketing margin were researched. The inventory identified only 26 stems of I. gabonensis among 35 farmers. The work revealed two main uses among the Agnis, the Baoulés, the Groussis, the Malinkés and the Morés. This is the consumption of almonds known by 100% of the respondents and the therapeutic use of the bark known by only 10% of the sample. Investigations showed an average gross marketing margin of 27%. Additional work will have to be made out to further enhance the bark and leaves. Also, we recommend the sowing of seeds or the maintenance of wildlings in degraded areas of cocoa trees with a view to sustainable management of this resource.

Fisheries management involves, among other things, knowledge of the actors and the catching gear used. These data are generally absent in the fisheries of Côte d'Ivoire. However, there is a strong fishing activity. To lead this study, surveys were conducted among fishermen and fishery administrators. The study of fishing activity in the area of Dioulabougou (Côte d’Ivoire, West Africa) in the district of Bouaflé done from November 2013 to February 2014 identified 88 fishermen. This population is composed of ivorians (39.77%) and foreigners (60.23%). The fishing activity is led by malians (Bambara ethnic group): 34.1%. Baoulé ethnic group (29.54% of ivorian fishermen) is the greatest ethnic group of ivorians. Two categories of fishermen stand in the fishing activity. We registered professional fishermen whose job is only fishing (84.1%) and professionals with another activity (4.5%). The fishing activity in Dioulabougou is dominated by adult aged more than 45 years (48%). Fishermen are predominantly illiterate at 42.04%. The fishing techniques used at Dioulabougou are conical fishing baskets (mesh and trunk of ronier), bamboo-traps, gillnets, bottom lines and shore seines. The illiterate situation of fishermen isa serious matter for sustainable management on fish’s resources.

This study was carried out in the Agbo I classified forest (6 ° 24 '- 6 ° 41' N, 4 ° 50 '- 4 ° 09' W), which covers 15,575 ha. It contributes to a better knowledge of the dense semi-deciduous moist forest of Nesogordonia papaverifera (A. Chev.) Cap. (Malvaceae) and Khayaivorensis A. Chev. (Meliaceae). The surface surveys coupled with the itinerant inventories made it possible to have an inventory of 686 species, which are divided into 428 genera and 101 families. The most abundant families are Fabaceae, Rubiaceae, Malvaceae, Apocynaceae, and Euphorbiaceae. Out of these species, 84.11% are phanerophytes and 3.50% are hemicryptophytes. In conclusion, this study improves the knowledge which is based on the composition, structure, and diversity of the woody vegetation of the Agbo I forest. The results show that the species richness of the Agbo I classified forest is important. However, this floristic richness of the Agbo I listed forest is sufficient to justify its protection and sustainable management for the conservation of biodiversity in Côte d'Ivoire.

This study proposes an assessment of the historical coastline (TDC) mobility of the Ivorian coastline, specifically the Grand-Bassam coastline (Côte d'Ivoire), and suggests reflections on the sustainable management of the coastal environment in Côte d'Ivoire, taking into account coastal erosion. The objective is to evaluate, using the MobiTC software, the spatio-temporal and statistical evolution of the morphology of the Grand-Bassam coastal zone in order to plan appropriate coastal developments. Specifically, it is to extract images on google earth, to treat them under MobiTC and to analyze the rate of spatio-temporary and statistical evolution of coastlines. To do this, data from QuickBird images provided by Google Earth from 1984, 1988, 1992, 1996, 2000, 2004, 2008, 2012 and 2016 in the study area were used. Different software was used for image processing. The ENVI 5.1 software allowed georeferencing and thresholding to make the images superimposable and highlight the baseline. The digitization of the images was done with ArcGis software. The QGIS 2.18 software was used to convert the .shp files to the mid / mif format of the MobiTC software. The latter makes it possible to understand the statistical evolution of the coastline dynamics from the creation of a baseline, the skeleton of envelopes and traces. The variations observed between 1984 and 2016 show a fattening of 0.23 m / year in some sectors and an erosion rate of 0.34 m / year in other sectors. It is noted that 62.79% of the coastline is accretion and 37.21% is eroding.

Cette étude a été conduite à Zuénoula, dans le but d’évaluer la disponibilité et le niveau de connaissance des plantes sauvages comestibles pouvant servir d’alternatives aux populations locales et contribuer ainsi à leur valorisation. Pour cela, des investigations ethnobotaniques ont été réalisées à l’aide de fiches d’enquête dans 5 localités auprès de 368 individus. Les plantes et les organes comestibles récoltés ont été identifiés au Centre National de Floristique (CNF) d’Abidjan. Ainsi, les 76 espèces récensées appartiennent à 36 familles et 62 genres et représentent 32,34 % des plantes sauvages comestibles recensées en Côte d’Ivoire. Les Fabaceae (33,34 %) et les Malvaceae (22,23 %) sont les familles les plus rencontrées et sont majoritairement sous forme d‘arbres (38,16 %) et d‘herbes (26,32 %). Concernant les parties utilisées, ce sont les feuilles (38,85 %) et les graines (07,45 %) qui sont plus consommées en repas contrairement aux fruits (40,43 %) souvent consommés comme friandise au lieu de cueillette. Les populations (62,23 %) qui ont une bonne connaissance de la flore locale comestible sont aujourd’hui confrontées à la disparition progressive d‘espèces autrefois prisées comme Glyphaea brevis, Irvingia gabonensis et Telfairia occidentalis. Enfin, la consommation de Bixa orellana et de Gymnema sylvestre, espèces très utilisées dans l’alimentation humaine et la médecine en Asie, a pour la première fois été révélée en Côte d‘Ivoire. La poursuite de cette étude par des analyses des valeurs nutritives des espèces les plus sollicitées est vivement souhaitée en vue de leur valorisation au plan nutritionnel.  This study was conducted in Zuénoula with the aim of assessing the local people’s level of knowledge on wild edible plants and the availability of these plants to serve as alternatives for the local population and thus contribute to their development. To achieve this, botanical surveys were carried out in 5 localities involving 368 persons. Plants and edible organs collected were identified at the Centre National de Floristique (CNF) in Abidjan. All 76 species recorded belong to 36 families and 62 genera, and they represent 32.34% of wild edible plants identified in Côte d'Ivoire. Fabaceae (33.34%) and Malvaceae (22.23%) were the most common families and are mainly trees (38.16%) and herbs (26.32%). Concerning the part of the plants used, leaves (38.85%) and seeds (07.45%) were the most consumed in meals, which is contrary to fruits (40.43%) often consumed as sweets at the harvesting sites. The majority of the population (62.23%), which has a good knowledge of the local edible flora, is today confronted with the progressive disparition of species once sought after such as Glyphaea brevis, Irvingia gabonensis, and Telfairia occidentalis. This study reveals for the first time the consumption in Côte d'Ivoire of two plants' species, Bixa orellana and Gymnema sylvestre, widely used in human food and medicine in Asia, highlighting the great diversity of the local flora. Since the nutritional potential of these species has never been studied in Côte d'Ivoire, additional research on the most sought-after species is highly recommended for their nutritional valorization.
