Full textAbstract:
This study provides evidence on the effectiveness of community controls in regulating the use of common agricultural land in Côte d'Ivoire and tests for factors such as group size, ethnic and income heterogeneity of the group, income and resource stock levels, in explaining the variation in effectiveness across communities. The results indicate significant deterioration in community controls. These results point towards the need for a comprehensive policy framework towards agriculture in general and land tenure in particular. The study also finds that smaller and ethnically homogenous communities are better able to coordinate their actions, thereby internalizing a higher proportion of the value of land as a factor of agricultural production than their large ethnically heterogenous counterparts. No evidence is, however, found in favour of income heterogeneity hindering or facilitating collective action.

Full textAbstract:
Agriculture has long been Côte d’Ivoire’s main source of export income and the first largest sector providing employment. For several decades, Ivorian agriculture remained unmodernized. The modernization of agriculture requires both public and private funding. Despite some efforts, financing of agriculture is not effective in Côte d'Ivoire due to the lack of real commitment from the private sector and commercial banks. The results showed that in the long-term agricultural credit and other variables have a positive and significant influence on agricultural added value. It is therefore recommended to increase agricultural credit and extend it to small producers.

Full textAbstract:
This paper provides a conceptual and empirical general equilibrium framework for the analysis of the impact of trade reform on welfare and the environment. The analysis is applied to Côte d'Ivoire explicitly considering externalities affecting biomass (natural vegetation), which is shown to be an important factor determining agricultural productivity.The simulation general equilibrium analysis shows that the agricultural output composition effect dominates the agricultural expansion effect for the case of complete trade liberalization. Thus, in this case trade liberalization causes a significant improvement in the rural biomass stock by cutting land area cultivated, increases agricultural productivity, and induces dramatic welfare gains. That is, trade liberalization is a win–win type of policy in this case. However, partial trade liberalization that only reduces protection to non-agricultural goods (and does not reduce tariffs to agricultural import substitutes and does not reduce export taxes) causes a further deterioration of the biomass resources and reduces welfare.

Full textAbstract:
Côte D'Ivoire retains a central place in discussions on the development of African capitalism. Dramatic increases in agricultural and industrial production in the post-colonial period, coupled with the régime's unequivocally liberal and pro-capitalist discourse, contributed to the image of the Ivoirian state as aggressively promoting the expansion of local and foreign capital. By the late 1970s, it was clear that a select stratum of Ivoirians had amassed private fortunes in the industrial sector, agro-industry, and real estate. Less clear is the significance of this fact for understanding the internal dynamics and development trajectory of Ivoirian capitalism. The idea that the Ivoirian bourgeoisie diversified from its base in agriculture to become one of the most dynamic and influential business classes in sub-Saharan Africa remains plausible, but it evokes no consensus among analysts. Indeed, students of Ivoirian capitalism have been more inclined to argue that the state itself remains the main source of private fortunes, that local capital is thoroughly subordinated to foreign capital, and that indigenous business interests are ensnared in the clientelistic networks of the régime.

Abstract:This article examines the effects of the post-2002 sociopolitical crisis in Abidjan, Côte d'Ivoire, on urban and peri-urban agriculture. Based on the case study of Abidjan, it argues for a conceptualization of sustainability that includes social as well as environmental dimensions and focuses on coping strategies of producers and merchants. In Abidjan, these strategies included internal migration within the city and its periphery, the use of organic fertilizers, and changes in market structure. The study illustrates how such strategies allowed producers to continue to supply produce to the market, despite the difficulties of war.

Women play a major role in the accession to food security because of their significant contribution to agriculture. However, very few data exists on women’s contribution to the Cote d’Ivoire fish production. The objective of this study was to evaluate the ability of fish farms owned by women to contribute to the fish production in Cote d'Ivoire. A survey has been conducted on women fish farms characteristics and their production capacity. Only 5.98% of 301 farms belonged to women with a contribution to the total production of 2.89%. They are mostly farmers (44.44%) aged 30 to 60 years (88.89%), native of the regions (66.67%) where they had their farms. Tilapia and catfish are the main species produced with a semi-intensive (83.33%) farming system in pond. The area of production is less than 1 hectare (77.78%). Commercial or farms-made feeds are preferably used as fish feeds. Women-owned farms production is characterized by the tilapia commercial weigh over 300 g (66.67%) and a yield of 1000 kg/ha/year (77.78%). By their choice of production system, feeds and their production capacity, women can contribute to set up a sustainable production environment of farm fish in Cote d'Ivoire.

SUMMARYImproving farmers’ knowledge of new technologies and creating conducive learning opportunities, with particular attention to the marginalized poor (women and youth), are major factors in the move towards sustainable agriculture. To explore the gender gap in agricultural knowledge acquisition and adoption in West Africa, we used baseline data collected in 2013 and 2014 in five countries (Benin, Côte d'Ivoire, Niger, Nigeria and Togo) with 499 surveyed households. The t-test and Kruskal–Wallis test were used for analysis. The most quoted source for acquiring knowledge on rice farming methods was ‘other farmers’, showing the importance of social capital for rural African farmers. In Benin, a gender gap was noted in rice farmers’ access to agricultural knowledge sources, with women being more advantaged. In Côte d'Ivoire, Niger, Nigeria and Togo, no significant gender gap was observed in rice farmers’ access to agricultural knowledge sources. Regarding the level of knowledge and use of rice farming methods in Côte d'Ivoire and Niger, significant gender gaps were observed. The gender approach to rural development is having impact in West Africa with regard to farmers’ access to agricultural information. However, interactive rural learning approaches (such as farmer-to-farmer video) need to be resorted to make the technologies’ principles well known and improve the ability of marginalized poor to adopt and or innovate with local or limited resources. This study leads to a better understanding of the relationship between gender, knowledge and use of agricultural technologies in order to enhance marginalized farmers’ adoption of improved innovations.

Cette étude examine la production de troupeaux bovins villageois principalement trypanotolérants, dans la région de Boundiali, au nord de la Côte d'Ivoire. Le but est d'évaluer la rentabilité de ce système de production dans une région affectée par la trypanosomose et d'identifier les principales contraintes économiques. Des données biologiques collectées entre janvier 1986 et décembre 1989 et des données économiques et financières collectées en 1988 sont utilisées dans un Modèle de Troupeau. Ce modèle bio-économique de simulation permet d'obtenir des projections sur 10 ans de la structure des troupeaux, de la production de lait et de viande, et des estimations de rentabilité. Les résultats indiquent une rentabilité économique très élevée pour l'économie ivoirienne. De plus, la récente dévaluation du franc CFA devrait accroître la compétitivité de l'élevage. Ces résultats sont encourageants au vu des efforts du gouvernement pour soutenir l'élevage. La rentabilité financière pour les producteurs est en revanche modeste, en particulier en raison des coûts élevés du gardiennage car les bouviers Peul reçoivent une large part du lait produit. Une augmentation de la productivité et de la rentabilité financière paraît difficile tant que subsiste ce système de gestion.

The threat which is on the forests and wooded spaces of Africa and particularly those of Côte d'Ivoire is accentuated over the years. The quoted leading causes are the land pressure related to demography, the anarchistic exploitation of the forest woody plants and itinerant agriculture. In many cases, the afforestation is the recommended palliative measure. But with which woody plants does one retimber in Côte d'Ivoire? Which assessment are previous initiatives made? On several occasions the exotic woody plants with rapid growth were used without success. The main objective of this study is to identify local woody plants with rapid growths of which the use will contribute to a significant degree to fast regeneration of our forests, degraded spaces and the post-farming fallow. Floristic inventories and measurements were carried out on the stems of Albizia adianthifolia and Albizia zygia in elementary plots of 400 m ² (20m X 20m). Two local arborescent Leguminous plants with rapid growth were identified for this purpose. They were: Albizia adianthifolia and Albizia zygia. The experiments showed that these species reach the maximas of their growth in height and thickness as from nine (9) years. The sowing of the fallow and/or spaces degraded by these woody species supports the fast regeneration of these degraded spaces.

This study focuses on mapping and identification of pollution factors in the Kan dam basin in Bouaké (Côte d'Ivoire); All through the use of GIS and field investigations. The consequences of socio-economic development on the Kan dam are important. Indeed, the watershed of the dam appears to be the outlet for all the waters (used and rain) of the town of Bouaké. The mapping of land use in the dam basin allows the identification of nuisance and pollution sources. Mainly five (05) types of nuisance and pollution activities were identified: urbanization (habitat zones); Agriculture (agricultural areas); Fishing (fishing zone); Poultry farming (poultry farming); Cattle breeding (pasture area).

Full textAbstract:
In Côte d'Ivoire, urban agriculture is expanding in several cities due to its proximity to consumers and its financial benefits. In the city of Daloa, several plant species are cultivated as food crops in market gardens. A survey based on semi-structured interviews was carried out among 19 people at 8 market gardening sites. This sector is controlled by functional illiterate persons who are more than 5 years’ experience. Eleven species included in 9 genera and 8 families and grouped into 5 types of vegetables were recorded. Carrot, Cabbage, Courgette, Spinach, Green Bean, Parsley, Lettuce and Tomato were the most grown vegetable. The most represented families were Apiaceae, Asteraceae and Liliaceae. Leafy vegetables (lettuce, cabbage, parsley) were the most grown. Market gardening generates monthly incomes depending on actor, species, and seasons. Thus, this sector provides an important source of income for local populations and deserves support from authorities.

Full textAbstract:
Background. The intensive use of insecticides in public health and agriculture has led to the development of insecticide resistances in malaria vectors across sub-Saharan Africa countries in the last two decades. The kdr target site point mutation which is among the best characterised resistance mechanisms seems to be changing its distribution patterns on the African continent. The 1014F kdr mutation originally described only in West Africa is spreading to East Africa while the 1014S kdr mutation originally described in East Africa, is spreading to West and Central Africa. However, the East-kdr mutation has not been reported in Côte d'Ivoire so far. Methods. Immature stages of Anopheles gambiae s.l. were collected from breeding sites at the outskirts of Yamoussoukro, Côte d'Ivoire. Emerging 3–5 day old adult female mosquitoes were tested for susceptibility to deltamethrin 0.05%, malathion 5%, bendiocarb 1% and dichlorodiphenyltrichloroethane (DDT) 4% according to WHO standard procedures. A total of 50 An. gambiae s.l. specimens were drawn at random for DNA extraction and identification down to the species level. A subsample of 30 mosquitoes was tested for the East-African kdr mutation using a Taqman assay. Results. The tested mosquito population appeared to be strongly resistant to deltamethrin (1.03% mortality), bendiocarb (38.46% mortality) and DDT (0% mortality) with probable resistance observed for malathion (92.47%). Among the 41 mosquitoes that were successfully characterized, An. coluzzii was predominant (68.3%) followed by An. gambiae s.s. (19.5%) and a few hybrids (7.3%). Out of 30 specimens genotyped for East-kdr, a single hybrid mosquito appeared to be heterozygous for the mutation. Conclusion. The present study revealed the presence of the East-kdr mutation in Côte d’Ivoire for the first time in An. gambiae and highlights the urgent need to start monitoring the allele and genotype frequencies.

Face à un appauvrissement des sols et une irrégularité des pluies du fait du changement climatique, une étude a été entreprise sur la culture du maïs au Centre-Nord de la Côte d’Ivoire. Elle avait pour objectif d’évaluer l’influence de quatre types de fumures sur le potentiel agronomique de deux génotypes de maïs (Zea mays L.) en cas de contrainte hydrique de fin de cycle et d’infertilité des sols. Le dispositif expérimental a été un split-plot, dont le premier facteur a été les fertilisants et le second, la variété. Les résultats ont montré que les fumures ont influencé les durées des phases végétative et reproductive en plus du rendement. Les fumures fiente de poulet et déjection de boeuf ont permis d’obtenir un rendement qui est égal à six fois celui obtenu avec le témoin de la variété à grain noir malgré la contrainte hydrique. Aussi, la fumure fiente de poulet a eu une tendance à réduire le cycle de culture et favoriser une meilleure croissance et un bon développement des plantes. L’utilisation de ces fumures en culture du maïs, pourrait constituer une alternative aux conséquences drastiques du changement climatique.

English Title: Effect of four types of fertilizers on the growth and productivity of two maize genotypes (Zea mays L.) in the event of late planting in Korhogo in North-Central Côte d'Ivoire
English Abstract
Faced with soil depletion and irregular rains due to climate change, a study was undertaken on maize cultivation in North-Central Côte d'Ivoire. Its objective was to assess the influence of four types of manure on the agronomic potential of two maize genotypes (Zea mays L.) in cases of water stress and soil infertility. The experimental set-up was a split-plot, the first five-level factor being fertilizers and the second two-level factor being variety. Observations were made on phenology, growth parameters and yield. The results showed that manure influenced vegetative and reproductive time, growth parameters and yield. In terms of yield, chicken droppings and beef droppings were the most effective. They yielded six times the yield obtained with the black-grain variety control despite the water constraint at the end of the cycle. Also, chicken manure has had a tendency to reduce the growing cycle and promote better growth and plant development. The use of these manure in maize cultivation could be an alternative to the drastic consequences of climate change.

Une étude portant sur les modalités d’élevage et le parasitisme digestif des ovins a été réalisée dans 3 régions du centre de la Côte d’Ivoire, d’Août 2017 à Avril 2018. Elle a comporté une enquête par questionnaire menée dans 25 élevages, et une enquête coprologique effectuée sur 550 ovins dans 12 de ces élevages. Les résultats de l’enquête par questionnaire montrent que le système de production le plus répandu demeure le système traditionnel (68% des élevages), suivi du système amélioré semi-intensif (20%) et enfin du système moderne intensif (12%). Les 3 élevages modernes de l’étude se sont révélés d’un niveau élevé de technicité et de productivité ; cependant les mesures d’hygiène peuvent encore y être améliorées. Les élevages traditionnels sont d’un niveau sanitaire médiocre, qui se traduit par un niveau d’infestation parasitaire des ovins plus élevé. En effet, la charge parasitaire moyenne des ovins des élevages traditionnels était de 428,0 œufs par gramme (opg) de fèces avec 81,7% des animaux excrétant moins de 500 opg ; pour les élevages semiintensifs, la moyenne était de 198,7 opg avec 84,1% des ovins excrétant moins de 500 opg ; et pour les élevages modernes intensifs, la moyenne était de 193,0 opg avec 99,2% des ovins excrétant moins de 500 opg. Ces différences étaient statistiquement significatives. L’identification des œufs par les examens coprologiques a permis de mettre en évidence la présence de strongles digestifs, de Trichuris sp, de Strongyloides papillosus, de Moniezia sp et des ookystes de coccidies du genre Eimeria. L’identification des espèces parasitaires après la coproculture a révélé que 75% des larves appartiennent au genre Haemonchus, 8,6% au genre Trichostrongylus, 8,2% au genre Strongyloides, 8% au genre Cooperia et 0,2% au genre Oesophagostomum.

It included a questionnaire survey conducted on 25 farms and a coprological study- carried out on 550 sheep in 12 of these farms. The results of the questionnaire survey showed that the most widespread production system remains the traditional system (68% of the farms), followed by the improved semi-intensive system (20%) and finally the modern intensive system (12%). The three modern farming methods in the study proved to be of high-level technicality and productivity, however, hygiene measures can still be improved. Traditional herds are of a poor health level, which results in a higher level of parasitic infestation of sheep. In fact, the average parasite burden of sheep in traditional farms was 428.0 eggs per gram (epg) of faeces with 81.7% of animals excreting less than 500 epg; for semi-intensive farms. The average was 198.7 epg with 84.1% of sheep excreting less than 500 epg; and for intensive modern breeding, the average was 193.0 epg with 99.2% of sheep excreting less than 500 epg. The identification of the eggs by the coprological examinations revealed the presence of digestive strongles, Trichuris sp, Strongyloides papillosus, Moniezia sp and coccidia oocysts of the genus Eimeria. Identification of parasite species after stool culture revealed that 75% of the larvae belong to the genus Haemonchus, 8.6% to the genus Trichostrongylus, 8.2% to the genus Strongyloides, 8% to the genus Cooperia and 0.2% to the genus Oesophagostomum.

Le système de production agricole des Fohobélé est basé sur une main d’oeuvre provenant principalement de la famille dite élargie et du nabonron qui est une institution sociale destinée à mutualiser la force de travail. A la suite de l’adoption de la culture de l’anacarde, l’économie locale s’est structurée autour d’une économie de plantation en remplacement de l’économie fondée sur la culture de rente qu’est le coton. Le présent article vise d’une part à connaitre l’impact de la culture de l’anacarde sur les structures sociales de mobilisation de la main d’oeuvre agricole des Fohobélé et d’autre part à découvrir les nouvelles stratégies de formation de la force de travail agricole. A travers des entretiens semi-directifs avec les acteurs locaux et des observations de terrain, il ressort de l’étude que l’adoption de cette nouvelle spéculation agricole a déstructuré les formes traditionnelles de la force de travail. La famille traditionnelle s’est éclatée pour laisser la place à des familles nucléaires. Le nabonron, forme d’entraide locale a disparu. La force de travail provient désormais de la famille nucléaire avec un rôle plus accru des femmes, des prestations monétarisées et de l’usage des produits chimiques dans l’agriculture.
The Fohobélé agricultural production system is based on a workforce mainly coming from the so-called extended family and the nabonron, which is a social institution intended to pool the labor force. Following the adoption of cashew cultivation, the local economy was structured around a plantation economy to replace the economy based on the cash crop of cotton. This article aims on the one hand to know the impact of cashew cultivation on the social structures of mobilization of the agricultural workforce of the Fohobélé and on the other hand to discover the new strategies of strength training agricultural work. Through semi-structured interviews with local actors and field observations, it emerges from the study that the adoption of this new agricultural speculation has deconstructed the traditional forms of the labor force. The traditional family has split up to make way for nuclear families. The nabonron, a form of local mutual aid, has disappeared. The labor force now comes from the nuclear family with a greater role for women, cash benefits and the use of chemicals in agriculture.

Trois légumineuses alimentaires (arachide, niébé et soja) ont été mises en avant culture de la tomate à Bouaké localisée au centre de la Côte d’Ivoire. Après la récolte des légumineuses, un essai de fertilisation de la tomate a été mis en place selon un dispositif en blocs randomisés complets avec trois répétions. Les antécédents culturaux des légumineuses ont été utilisés comme source de fertilisation de la tomate. Deux témoins dont un sans aucune source de fertilisation et un autre témoin de référence qui est la pratique habituelle utilisant des engrais de fond (NPK) et de couverture (urée et sulfate de potasse). Les résultats obtenus ont montré que les paramètres de croissance, de développement végétatif et des stades phénologiques ont évolué indépendamment des sources de fertilisation. Par contre, la plupart des composantes du rendement ont été sources de variabilité entre les traitements. En effet, l’antécédent niébé a généré les rendements brut et net les plus élevés (7, 38 t/ha) par rapport autres traitements. Les traitements Témoin (T0), la référence (T1), les antécédentes culturales arachides et soja ont obtenu respectivement 2,85 ; 5,31 ; 4,80 et 2,35 t/ha. Le niébé pourrait être recommandé pour la culture de la tomate, vu la performance de son antécédent cultural.
In order to propose agroecological methods to improve the quality and quantity of vegetable production and also to preserve the environment from the abusive use of synthetic inputs, the exploitation of the after-effect of legumes was undertaken. The objective of this study is to evaluate the effect of food legumes on tomato productivity. Three food legumes (groundnut, cowpea and soybean) were put forward for tomato cultivation in Bouaké located in central Côte d'Ivoire. After harvesting the legumes, a tomato fertilization trial was set up in a complete randomized block design with three replications. The crop background of the legumes was used as a source of fertilizer for the tomato. Two controls, one without any source of fertilization and another reference control which is the usual practice using base (NPK) and cover fertilizers (urea and sulphate of potash). The results obtained showed that the parameters of growth, vegetative development and phenological stages evolved independently of the sources of fertilization. However, most of the yield components showed variability between treatments. Indeed, the cowpea crop history generated the highest gross and net yields (7.38 t/ha) compared to other treatments. The control (T0), reference (T1), groundnut and soybean treatments obtained 2.85, 5.31, 4.80 and 2.35 t/ha respectively. Cowpea could be recommended for tomato cultivation, given the performance of its crop history.

In the area of Lakota (Midwest, Côte d'Ivoire), where the vegetation is a semi-deciduous forest, cacao growing is practiced by people from different origins. Cacao cropping techniques seem to be influenced by some social and cultural habits, according to the people and the agroecological areas. The present study aimed to understand(1) the cacao cropping systems and to identify(2) the reasons underlying the choice of vegetal species combined to cacao trees in these rural communities. To achieve this goal, interviews were realised with cacao farmers of four villages of the area. These interviews concern farmers’ profiles, the former agriculture practices, the variety of the cultivated cacao and the plants combined to cacao trees. The results show that among the 223 interviewed farmers, 72 (32.3% of the farmers) are natives, 42 (18.8% of the farmers) are immigrants and 109 (48.9% of the farmers) are non-native Ivorians. In total, 77 species regularly combined to cacao trees were named by the farmers and they can be divided into local species and exotic species. Plots ordination shows three agroforestry systems according to ethnic group of the locality. Cacao farms with the large proportion of local species are owned by Lakota native people "Dida". The exotic species are dominant in cacao farms that belong to immigrants (Malian, Burkina Faso and Guinean people) and "Malinké" people (a non-native ivorian ethnic group). The Akan people (a non-native ivorian ethnic group) combine in a same proportions exotic and local species in their cacao farms.

SUMMARYBiomass burning has links with a number of global concerns including soil health, food security and climate change. In central Côte d'Ivoire (West Africa), we conducted a field study to compare nutrient losses, soil fertility and yam yield in slash-and-burn versus slash-and-mulch agriculture. Trials involved five sites established in the dominant Chromolaena odorata fallows of the region, each consisting of paired plots: slash and burnt biomass (SB) versus slashed and unburnt biomass, but left to serve as mulch (SM). Carbon and five elemental nutrients were assessed in the aboveground biomass prior to burning and in ash after fires; losses were assessed by subtraction. The greatest proportions of loss occurred with C (95%), N (95%) and K (74%), corresponding to losses into the atmosphere of 3532 ± 408, 200 ± 36, 132 ± 36 kg ha−1. Six weeks after the fire, soil properties were assessed: soil organic C, total N and Mg2+ were higher in SM than in SB sites. At final harvest, yam tuber yield was twice as large in SM as in SB (18 ± 4 vs. 9 ± 2 Mg ha−1) with soil C, total N and K+ as the main influential soil parameters. The key finding was that the elements lost in greatest proportion during burning were those mostly influencing yam yields. Because a clear negative relationship between biomass burning and yam production has been established the promotion of the more productive, alternate slash-and-mulch system compared to slash-and-burn system, is warranted. The findings of our research can be used in support of developing a sustainable yam production system in the region and in West Africa more generally.

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 conversion of natural ecosystems to agriculture is recognized as the current major cause of biodiversity loss. Given large expanses of land that is under agriculture worldwide, this study, carried out in 2013, aimed to examine the contribution of mango orchards to the restoration of hypogenous termite in northern Côte d'Ivoire. Using the TSBF (Tropical Soil Biology and Fertility) monolith method of soil macrofauna estimation, termites were collected in seven age classes of mango tree orchards (class 1: <5 years; class 2: 5–9 years; class 3: 10–14 years; class 4: 15–19 years; class 5: 20–24 years; class 6: 25–29 years; class 7: 30 years and over) and compared with termites collected from the savannah. A total of 16 species of termite were collected in all the study plots. The species richness, low in young orchards of classes 1 and 2 (05 species), increases to reach its maximum in old orchards of more than 30 years (13 species). These old orchards would be even richer and more diversified in termite species than savannah (10 species). Termites were less abundant in young orchard of class 1 (151.33±87.35 Individuals/m2) and more abundant in the old orchards of class 7 (344.88±119.90 ind./ m2). In the young orchards of class 1, termites were more prevalent in the 20-30 cm depth (7.92%) and in the old orchards of class 7, termites were found more at the surface between 0-10 cm depth (67.26%). Soil-feeders were absent in the young orchards but were abundant in the old orchard of class 7 (519 individuals). This study showed that in this highly disturbed region, mango orchards are re-colonized by termite communities. These results encourage the establishment of mango orchards to allow natural regeneration after agricultural disturbances.

Aims: The aim of this work is to assess the level of aflatoxins contamination in maize produced in five regions (Poro, Hambol, Gontougo, Gbêkê, Indénié-Djuablin) of Côte d'Ivoire.
Place and duration of study: In this study 375 samples of maize (grains, cobs, spathes) were taken from February 2016 to January 2017 and the aflatoxin analyses were carried out at the Biotechnology Laboratory, Agriculture and Development of Biological Resources of the Félix Houphouët-Boigny University.
Methodology: The aflatoxins (B1, B2, G1 and G2) were extracted and assayed by High Performance Liquid Chromatography (HPLC) according to the AOAC method.
Results: The results indicate the presence of aflatoxins B1, B2, G1 and G2 in all forms of maize (grains, cobs, spathes) and in the five regions chosen for the study. The mean concentrations of aflatoxins B1 (AFB1) and the total aflatoxins (AFT) varied from 0.79 ± 0.04 µg/kg to 130.31 ± 22.56 µg/kg and from 2.63 ± 2,35 µg/kg to 169.13 ± 40.39 µg/kg respectively. samples from Indénié-Djuablin, Hambol and Gountougo regions showed the highest proportions of non-compliance with the european Union limit of 5 μg/kg and 10 μg/kg. Regarding AFB1, these proportions vary from 0% to 46% in the regions of Gbêkê, Poro and Hambol, while they are between 54% and 96% in the regions of Indénié-Djuablin and Gontougo. For total aflatoxins, the proportions of non-compliant samples were between 0% and 40% (Gbêkê and Poro), 12% and 56% (Hambol), 56% and 96% (Indénié-Djuablin and Gontougo).
Conclusion: These results demonstrate a need for monitoring of maize production by stakeholders in the sector who should adopt good agricultural practices.

Aims : The aim of this work is to take stock of the level of ochratoxin A (OTA), fumonisin B1 (FB1) and zearalenone (ZEA) contamination in maize produced in Cote d'Ivoire in order to help improve its quality.
Study Design: Maize samples (375) were taken in five producing regions (Poro, Hambol, Gontougo, Gbêkê, Indénié-Djuablin).
Place and Duration of Study: the collection was carried out on maize in grain, on the cob and in spathe from February 2016 to January 2017. Then, the analyzes were carried out at the Biotechnology Laboratory, Agriculture and Development of Biological Resources of the Félix HOUPHOUËT-BOIGNY University.
Methodology: The determination of ochratoxin A, fumonisin B1 and zearalenone was carried out according to the methods of regulation No. 401/2006/EC, AFNOR, Miraglia and Brera.
Results: The results indicate the presence of ochratoxin A, fumonisin B1 and zearalenone in all forms of maize (grains, cob, spathes) and the five regions visited. However, the average concentrations of fumonisin B1 and zearalenone are respectively 27.46 µg/kg-1999.22 µg/kg and 8.48 µg/kg-341.84 µg/kg and are lower than the prescribed reference standards (2000 µg/kg ; 500 µg/kg). For ochratoxin A, the average concentrations vary from 0.83 µg/kg to 14.38 µg/kg ; 1.92 µg/kg to 18.60 µg/kg and 2.21 µg/kg to 134.89 µg/kg respectively for grains, cob and spathes.
Samples from the Regions of Poro, Gbêkê and Hambol have mean concentrations below the maximum reference limit of 5µg/kg. Thus, variability in the sanitary quality of maize was demonstrated from one region to another, regardless of the form of the maize. Based on the principal component analysis, spathes represent the form of maize most prone to high contamination regardless of mycotoxin and région.
Conclusion: The searching alternative storage methods and the right form of maize storage could be a solution to the high mycotoxin contamination of marketed maize.

1 RESUME Objectif : Le palmier à huile, source d’huile végétale, est sujet aux attaques de ravageurs dont la mineuse des feuilles, Coelaenomenodera lameensis BERTI ET MARIAU (Coleoptera : Chrysomelidae, Hispinae). Ce ravageur cause d’importants dégâts dans les palmeraies en Côte d’Ivoire. Dans un contexte actuel d’agriculture durable et de préservation de l’environnement, l’on se tourne de plus en plus vers la lutte biologique en réduisant l’utilisation de produits chimiques. Cette étude a donc été initiée, avec pour objectif de contribuer à la lutte intégrée contre C. lameensis par l’utilisation d’un ennemi naturel, les fourmis Oecophylla longinoda Latreille (Hymenoptera : Formicidae). Méthodologie et Résultats : L’étude a été conduite sur des parcelles d’âges différents (4 ans, 10 ans et 12 ans) à la station CNRA de la Mé où la dynamique des populations de C. lamensis a été suivie en relation avec la présence de O. longinoda. Les résultats révèlent qu’il existe une forte corrélation négative entre la densité des larves et des adultes de C. lameensis et le taux de présence de O. longinoda. Les populations de C. lameensis sont réduites avec la présence de O. longinoda sur les palmes. Conclusion : Les fourmis oecophylles sont donc de potentiels agents de lutte biologique pour le contrôle des populations de C. lameensis. Impact of red ants Oecophylla longinoda Latreille (Hymenoptera: Formicidae) on the population dynamics of Coelaenomenodera lameensis Berti & Mariau (Coleoptera: Chrysomelidae), the main pest of the oil palm Elaeis guineensis JACQ. in Côte d'Ivoire. ABSTRACT Objective: Oil palm, a source of vegetable oil, is prone to pest attacks, including the leaf miner, Coelaenomenodera lameensis Berti And Mariau (Coleoptera: Chrysomelidae, Hispinae). This pest causes significant damage in the palm groves in Côte d’Ivoire. In a current context of sustainable agriculture and preservation of the environment, we are turning more and more towards biological control by reducing the use of chemicals. This Kouassi et al., 2019 Journal of Animal & Plant Sciences (J.Anim.Plant Sci.

Methodology and Results: The study was conducted on plots of different ages (4 years old, 10 years old and 12 years old) at the CNRA station in La Mé, where the population dynamics of C. lamensis were monitored in relation to the presence of O. longinoda. The results reveal that there is a strong negative correlation between larval and adult density of C. lameensis and the rate of occurrence of O. longinoda. The populations of C. lameensis are reduced with the presence of O. longinoda on the palms. Conclusion: Oecophyllous ants are therefore potential biological control agents for the control of C. lameensis populations.
