The Impact

The impact of two agricultural insecticides on larvae of Anopheles gambiae, the malaria vector, has been studied in an experimental scope in Bouaké, Côte d'Ivoire. The Furadan® (carbofuran) and the Décis® (deltamethrin), pesticides commonly used against pests of rice, were applied in irrigated rice bins 15 days after sowing or transplanting, using operational doses of 28 kg / ha and 1l / ha recommended by the manufacturer. Each rice paddy was replicated 3 times and all these replicas were arranged in 3 randomized complete block. Larvae were sampled according to Dipping method before and after insecticide treatments. Water lockers was also charged for persistence tests. Determining the density live larvae showed total disappearance thereof in the 3rd day (3 days after treatment) before reappearing on the 5th day. Insecticides persistence tests have given a larval mortality at 1 day 97.8% to 100% for the Furadan® and 45.92% to 86.45% for the Décis®. This mortality was less than 50% for both insecticides on the 5th day. In Conclusion insecticides used (Décis®, Furadan®), induce a high mortality of larvae of Anopheles gambiae. However, if these insecticides have a low persistence (<1 week) that their activity period does not cover the proliferation period of this species in irrigated rice (2-4 weeks).

The Impact

Abstract Writing about Zophopetes cerymica (which they considered more common) and P. laufella combined, Mariau and Morin (1974) state that attacks can be on palms of all ages, including young palms recently planted out. At this age, defoliation of the plants delays their subsequent development. Outbreaks on older trees are rarer, and the damage often less important; these attacks are generally localized at the edge of plantations. Mariau et al. (1981) add that the highest fronds are the most often damaged. Herder et al. (1994) refer to regular outbreaks of P. laufella on oil palm in southern Côte d'Ivoire. There are no more substantive reports on the impact of the feeding damage by these hesperiids.

The Impact

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.

The Impact

The inclusion of education in post-conflict reconstruction in a transitional justice process goes far beyond physical construction and educational facilities to become part of national educational planning and policy. The issue of education in post-conflict periods is at the level of the national education system in general and of educational policies and strategies in particular. In Côte d’Ivoire, as in other countries emerging from violent conflict, even if the issue of education can be identified in the structural and direct causes of the occurrence of conflicts, it must be recognized that the impact of these conflicts on education remains considerable at different levels. Thus, taking account of its consequences in post-conflict reconstruction in the context of transitional justice is of great interest both for its contribution to economic growth and for the promotion of fundamental human rights and social cohesion. A full involvement of education in the transitional justice process is a real potential for mutual reinforcement in the reconstruction process. Practical synergies between education and transitional justice call for closer collaboration between education and transitional justice actors.

The Impact

The armed conflict that ravaged Côte d'Ivoire after the post-election crisis in november 2010 was sparked by several factors (land disputes, armed uprising of september 2002, tribal militias conquest of state power). In the regions of Guémon and Cavally that formed the epicenter of the war, intercommunal land disputes were instrumental in the outbreak of the war. These tensions between peasants have long caused confusion in the far west forest and contributed in part to the social division between indigenous and migrant communities. This qualitative study based on the phenomenological approach and firstly analyses the dynamics of these communal land disputes before the post-election crisis of 2010. Then, it situates the impact of these conflicts in the social division between communities.

The Impact

Since thirty years, four Australian Acacias species are introduced and studied in Anguédédou Research station. The station research is located in evergreen forest in the south of Côte d'Ivoire. The objective of the introduction of these species, is to rehabilitate degraded grounds and fallow after growing. The study aims at appreciating the impact of Acacia species on floristic diversity and the regeneration of forest species. For collecting data, we use quadrat method (35 x 50 m and 6 x 6 m).This method permitted the inventory of 212 species on 1.05 ha. Among these species, 1.89 % are Ivorian endemic species and 11.32 % are endemic of West African flora. The flora under the different species of Acacia are relatively diversified and dense. The majority of plant inventoried under Acacia species have small diameters. The highest specific richness average per plots (36 m2) were noted in the 11 years old parcels of Acacia mangium (26.20±2.34) and 27 years old parcels of Acacia auriculaeformis (25.40±2.34) and Acacia crassicarpa (30.60±2.34). The mean values of diameters (dbh ≥ 2.5 cm) fluctuate from 2.94±0.56 cm for the 8 years old stands of Acacia mangium to 8.09±0.56 cm for the 27 years old settlements of Acacia crassicarpa. The results show that leguminous trees can be used for recolonization of the deforested areas in order to rebuild quickly their plant biodiversity.
