The Relationship

The present study evaluates the impact of climate variability on water resources and population health in the coastal area of Cote d’Ivoire between Abidjan and Aboisso. First, hydroclimatic methods (Nicholson index) and statistical tests (Pettitt test, Hubert segmentation) were used for variability characterisation. Then, Thornthwaite Water balance method was used to evaluate water availability for aquifers recharge. Coefficient depletion method was also used to assess the impact of climate variability on surface water resources. The relationship between diseases occurence (AhigbeKoffikro and Samo) and rainfall pattern was evaluated through descriptive method. The results revealed important fluctuations of water resources levels at that time. The relationship rainfall-runoff showed with synchron trend that rivers flows regime was linked to rainfall. The impact on groundwater resources was explained by deficit of infiltrated water of about 35.49% and 22.61% after 1982 break at Abidjan airport and Bingerville stations respectively. Concerning health, 63% of malaria cases was observed against 2.85% for diarrhoea and 2.35% for helminthiasis. There was a strong relationship between rainfall and the diseases (malaria and diarrhoea).

The Impact

This study evaluates the impact of climate variability on wildfire regime in the N’Zi River Watershed (NRW) in central Côte d’Ivoire. For that purpose, MODIS active fire and monthly burned area data are used to evaluate wildfire occurrence, impacts and trends. Wildfire data are compared to past trends of different climatic parameters extracted from long-term meteorological records. Generalized additive models and Spearman correlations are used to evaluate the relationships between climate variables and wildfire occurrence. Seasonal Kendall and Sen’s slope methods were used for trend analysis. Results showed that from 2001 to 2016, 19,156 wildfire occurrences are recorded in the NRW, of which 4443 wildfire events are observed in forest, 9536 in pre-forest, and 5177 in Sudanian zones. The burned areas are evaluated at 71,979.7 km2, of which 10,488.41 km2 were registered in forest, 33,211.96 km2 in pre-forest, and 28,279.33 km2 in Sudanian zones. A downward trend is observed in fire records. The results indicates a strong correlation between some climatic variables and wildfire regime in this ecoregion. These correlations can be used to develop models that could be used as prediction tools for better management of fire regimes and support decision-making in the NRW.

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.
