The mountainous relief of the West of Côte d'Ivoire and the large savannahs next to forests didn’t make this zone very excellent for cocoa production. However, for the last decade, an important influx of farming population has been observed in this area. The objective of this study is to analyze the dynamics of the settlement of migrant farmers in the West region of Côte d’Ivoire, using the department of Biankouma as a case of study. So, individual surveys were conducted among 203 cocoa farmers from 15 villages in the department of Biankouma, who had migrated to this region, It was found that the majority of these farmers are natives of Côte d'Ivoire (38.3%) and non-natives (33.5%) from countries in the West Africa region. The migratory flow to this region is mainly internal, with 95.6% of farmers coming from 11 Districts and 55 localities in the country. While initially (i.e., before 1985), farmers came from towns near Duékoué (11.8%), these waves of movement from towns in neighboring districts (Bas-Sassandra and Sassandra-Marahoué) to the Western Region will experience their highest rates between 2002 and 2013. Observations drawn from our research findings support the hypothesis that the political-military crisis that the country has experienced has accentuated migratory flows of farmers for cocoa production in western Côte d'Ivoire and these migratory flows could be the cause of the degradation of forest cover in the Biankouma Department.

Intensive cocoa production in Côte d’Ivoire, the world’s leading cocoa producer, has grown at the expense of forest cover. To reverse this trend, the country has adopted a “zero deforestation” agricultural policy and committed to rehabilitating its forest cover through the planting of high-value tree species in cocoa landscapes using a participatory approach. However, little is known regarding the factors influencing farmers’ introduction of high-value tree species to cocoa landscapes. We tested the hypothesis that ten previously reported factors to influence agroforestry system adoption to predict the number and choice of tree species that farmers introduce to cocoa farms. We interviewed 683 households in the cocoa-producing zone of Côte d’Ivoire and counted tree species on their cocoa farms. On average, two tree species were recorded per surveyed farm. Generalized Poisson regression models revealed that, in the cocoa production area, experience in tree planting and expected benefits, including income and food, influence tree species introduction through planting or “retention” when clearing land for cocoa establishment. The age of the farmer also influenced (p = 0.017) farmers’ tree species planting on cocoa farms. Fewer tree species were introduced into current intensive cocoa-production areas than in “old cocoa-loops” and forested areas. The number of tree species introduced to cocoa farms increased with expected benefits and experience in tree planting. The number of planted tree species also increased with farmers’ age. Tree species were mostly selected for the provision of shade to cocoa, production of useful tree products (38%), and income from the sale of these products (7%). Fruit tree species were the most planted, while timber tree species were mostly spared when clearing land for cocoa production.

In Côte d'Ivoire, the S2 strain of Rice yellow mottle virus (RYMV) predominated in the forested zones, including the “rice belt” to the west, in each of the cropping systems where rice was grown. The S1 strain occurred more frequently in the northern Guinean savanna, and only S1 isolates were found further north in the Sahelo-Soudanian zones. In mixed infection, S2 dominated over S1 both in viral capsid and RNA contents under temperature regimes encompassing those observed in savanna and forested zones of Côte d'Ivoire. There was no evidence of interactions in virus accumulation between the West African strains S1 or S2 with the more distantly related East African strain S4. Field trials emphasized the impact of RYMV, which induced yield losses of 40 to 60% in several widely grown cultivars of Oryza sativa indica and O. sativa japonica. We report the high resistance of the O. indica cv. Gigante under field conditions which was apparent with all the S1 and S2 isolates tested. Responses to RYMV infection of several cultivars were isolate dependent. With most differential cultivars, responses were not strain specific, with the exception of the O. japonica cv. Idsa6, in which the S2 isolates always induced higher yield losses than the S1 isolates.

Like Côte d’Ivoire forest area, Abengourou department has not escaped anthropic pressure. The forest in this area was the scene of intense Cocoa farming activities. However, due to the weaknesses and constraints observed in the Cocoa sector, it has been seen that from years 1990 - 2000, most of the farmers have abandoned their Cocoa farms in favor of a gradual conversion in Rubber farming. In fact, this crop is considered to be a new booming income crop that tends to improve and guarantee the farmer’s life quality. This situation leads to an amalgam for the growing of Cocoa or Rubber. This study aims to determine the impact of Cocoa and Rubber farms on the farmer’s life quality in Abengourou (Côte d’Ivoire). Thus, field missions, documents analyze and directive surveys of farmers, cartographic and statistical processing have made it possible to establish correlations between Rubber tree or Cocoa farming and the farmer’s life quality. It follows from the correlations, that after analysis, the Rubber tree would have a positive influence on the farmer’s life quality than Cocoa. Moreover, Human Development Index (HDI) was measured respectively between the Cocoa and Rubber growers in the study area. The HDI of the Cocoa farmers is 0.455 and that of Rubber is estimated to 0.461. So, it is confirmed from these analyses that, in 2016, the growing of Rubber improves the farmer’s life quality more than that of Cocoa in the study area.

Preserving the forest is a "vital" action for maintaining the climate balance and promoting eco-tourism. The history mentions that the Ivorian forests played an important role in the dynamics of the development of the country because they sheltered a great diversity floristic and wildlife. Unfortunately, from 16 million hectares at the beginning of the last century (1900), the dense rainforest increased to 9 million hectares in 1965 and 3 million hectares in 1991. Today, it is estimated at about 2.5 million hectares. This situation is attributable to extensive agriculture based on the technique of shifting cultivation, the overexploitation of the forest with timber and wood energy and bush fires. Moreover, the phenomenon of forest infiltration with regard to the occupation or colonization of forest areas, particularly in the south-west of the country by migrants to build houses and / or villages, is an important factor in the disappearance of the forest. Also, successive crises that the country has experienced since 1999 until 2010 (post-election), with periods of tension, have led to mass displacements of populations. This regrouping of the populations in turn caused the clearing of the forest areas for their relocation. Thus, from the analysis of the situation of forest pressure in Côte d'Ivoire, the Ministry in charge of the management of the Ivorian forest cover indicates that the accelerated rate of destruction of Ivorian forests has today reached an estimated average of 450,000 hectares a year. The forest situation is catastrophic, if corrective measures are not taken and put into effect, the forest cover is supposed to disappear around 2040. The present work attempts to contribute to the level of reflection undertaken to improve the management of the sector. Résumé: Préserver la forêt est une action « vitale » pour le maintien de l’équilibre climatique et la promotion de l’éco-tourisme. L’histoire mentionne que les forêts ivoiriennes ont joué un rôle important dans la dynamique du développement du pays car elles abritaient une grande diversité floristique et faunique. Malheureusement, de 16 millions d’hectares au début du siècle dernier (année 1900), la forêt dense humide est passée à 9 millions d’hectares en 1965 et à 3 millions d’hectares en 1991. Aujourd’hui, elle est estimée à environ 2,5 millions d’hectares. Cette situation est imputable à l’agriculture extensive basée sur la technique des cultures itinérantes sur brûlis, la surexploitation de la forêt en bois d’œuvre et bois énergie et les feux de brousse. Par ailleurs, le phénomène de l’infiltration des forêts au regard de l’occupation ou la colonisation des zones forestières notamment du Sud-Ouest du pays par des migrants pour bâtir les habitations et/ou des villages est un facteur important de la disparition du couvert forestier.Egalement, les crises successives qu’a connues le pays depuis 1999 jusqu’en 2010 (post-électorale), populations. Ce regroupement des populations à son tour, a occasionné le défrichement des zones forestières pour leur relocalisation. Ainsi, de l’analyse de la situation des pressions sur les forêts en Côte d’Ivoire, le ministère en charge de la gestion du couvert forestier ivoirien indique que le rythme accéléré de destruction des forêts ivoiriennes a atteint de nos jours une moyenne estimée à 450.000 hectares par an. La situation des forêts est catastrophique, si des mesures correctives ne sont pas entreprises et mises en vigueur, le couvert forestier doit en principe disparaitre vers 2040. Le présent travail tente d’apporter sa contribution au niveau des réflexions engagées pour améliorer la gestion du secteur.

The cocoa tree is a very important plant in Côte d'Ivoire (formerly known as Ivory Coast) with a production of 2,15 million  tons. In spite of this performance, cocoa production is attacked by several pests of which the emerging ones are Pseudotheraptus devastans (Distant). These insects  attack  cherelles,  pods, gourmands and young shoots. This study aims to locate these pests and determine their importance in the different cocoa production areas. The device used is total  randomization. The leaching carried out in the orchard revealed the presence of P.devastans in all the cocoa producing districts. The means were 0,02 ± 0,00 to 2,35 ± 0,38 P. devastans  / tree.  The  districts of Sassandra-Marahoué, Comoé and Montagnes recorded  more  P.devastans.  However, the districts of Bas-Sassandra, Lagunes et Lacs had fewer P.devastans.
