Water is an indispensable resource for all activities developed by man. Water resources are indispensable for the survival of the populations of the Lobo watershed in Nibéhibé. They offer many multidimensional services. Around these important resources, social actors have different ways of perceiving them. This is why their management comes up against a difference in logic and action on the part of the different stakeholders. Thus, it must be noted that there is a crystallization of social relations between the different groups of actors involved and this is based on conflicts of use and the intensity of water scarcity. The objective of this study is to show the relationship between management mode and conflicts of use of water resources in the Lobo watershed in Nibéhibé. To achieve this objective, the methodology was based on the triptych documentary research, interview and questionnaire survey. The documentary research consisted in defining the contours of the subject in order to better understand it. Then, the interviews carried out with the actors of the water sector in the Lobo basin made it possible to collect information on the perception and the mode of management of the water resources in the basin. Finally, using the simple random selection method without discount and the use of a statistical equation, a sample of 384 households spread over the entire catchment area served as the basis for our surveys. Population surveys, combined with spatially referenced data under a GIS, have made it possible to map the spatial distribution of water supply sites on the one hand, and the spatial distribution of water-related conflict types on the other. The results show that the population has a wide variety of water supply sources. Moreover, the current management mode is either liberal (or private) or participatory (or community-based) depending on the type of water resource (surface or groundwater) and on the perception of the actors with regard to water.  Thus, the different uses generate conflicts that are perceived between cultural actors (indigenous) and economic actors such as SODECI (Water Distribution Company in Côte d'Ivoire) and fishermen (non-indigenous). There are also conflicts between women, which can be summarized as disputes over water points and distrust between different communities. An integrated management of water resources in this watershed would therefore be beneficial to all stakeholders.

Schistosomiasis poses a considerable public health burden in sub- Saharan Africa and a sound understanding of the spatial distribution facilitates to better target control interventions. The objectives of this study were i) to assess the prevalence of <em>Schistosoma mansoni</em> among school-aged children in four regions of western Côte d’Ivoire; ii) to determine demographic, climatic and environmental factors that influence the distribution of <em>S. mansoni</em>; and iii) to map and predict the distribution of S. mansoni in non-sampled locations. Parasitological surveys were carried out in 264 schools from June to December 2011. In each school, we aimed to examine 50 children for <em>S. mansoni</em> infection using duplicate Kato-Katz thick smears. Schools were georeferenced using a hand-held global positioning system receiver. Demographic data were obtained from readily available school lists, while climatic and environmental data were extracted from open-access remote sensing databases. Multivariable, binary non-spatial models and a Bayesian geostatistical logistic regression model were used to identify demographic, climatic and environmental risk factors for S. mansoni infection. Risk maps were developed based on observed <em>S. mansoni</em> prevalences and using Bayesian geostatistical models to predict prevalences at non-sampled locations. Overall, 12,462 children provided a sufficiently large stool sample to perform at least one Kato-Katz thick smear. The observed overall prevalence of S. mansoni infection was 39.9%, ranging from 0 to 100% at the unit of the school. Bayesian geostatistical analysis revealed that age, sex, altitude and difference between land surface temperature at day and night were significantly associated with <em>S. mansoni</em> infection. The <em>S. mansoni</em> risk map presented here is being been used by the national schistosomiasis control programme for spatial targeting of praziquantel and other interventions.

Cacao (Theobroma cacao L.) was introduced into West Africa from South America during the nineteenth century. However, cacao swollen shoot disease (CSSD) was first observed in Ghana in 1936 and, later, discovered in Nigeria, Côte d’Ivoire, Togo, and Sierra Leone. The objectives of this work were to assess the genetic diversity and spatial distribution of the Cacao swollen shoot virus (CSSV) in Ghana and investigate the origin and spread of the virus by identifying alternative host plants. Results obtained from polymerase chain reaction amplifications and phylogenetic relationship analyses of infected cacao and alternative host plants collected from the cacao-growing regions in Ghana revealed the existence of nine CSSV groups, A, B, C, E, G, J, K, L and M, with six groups detected for the first time in Ghana. The CSSV groups in Ghana are very divergent and correspond to at least five different putative species, according to the International Committee on Taxonomy of Viruses recommendations (A, B-C complex, G, E, and M), with the M species only being detected in the alternate host Ceiba pentandra. The spatial distribution of the different molecular groups in Togo, Côte d’Ivoire, and Ghana makes it difficult to predict a single origin for CSSV among the West African cacao-growing countries.
