The Impact

Abstract Background Burkina Faso has one of the highest malaria burdens in sub-Saharan Africa despite the mass deployment of insecticide-treated nets (ITNs) and use of seasonal malaria chemoprevention (SMC) in children aged up to 5 years. Identification of risk factors for Plasmodium falciparum infection in rural Burkina Faso could help to identify and target malaria control measures. Methods A cross-sectional survey of 1,199 children and adults was conducted during the peak malaria transmission season in south-west Burkina Faso in 2017. Logistic regression was used to identify risk factors for microscopically confirmed P. falciparum infection. A malaria transmission dynamic model was used to determine the impact on malaria cases averted of administering SMC to children aged 5–15 year old. Results P. falciparum prevalence was 32.8% in the study population. Children aged 5 to < 10 years old were at 3.74 times the odds (95% CI = 2.68–5.22, p < 0.001) and children aged 10 to 15 years old at 3.14 times the odds (95% CI = 1.20–8.21, p = 0.02) of P. falciparum infection compared to children aged less than 5 years old. Administration of SMC to children aged up to 10 years is predicted to avert an additional 57 malaria cases per 1000 population per year (9.4% reduction) and administration to children aged up to 15 years would avert an additional 89 malaria cases per 1000 population per year (14.6% reduction) in the Cascades Region, assuming coverage of pyrethroid-piperonyl butoxide ITNs. Conclusion Malaria infections were high in all age strata, although highest in children aged 5 to 15 years, despite roll out of core malaria control interventions. Given the burden of infection in school-age children, extension of the eligibility criteria for SMC could help reduce the burden of malaria in Burkina Faso and other countries in the region.

The Djarkadougou gold prospect is located on the Birimian greenstone belt of the Houndé exploration permit held by the company Orezone Inc. The permit is at 275 km far from the capital Ouagadougou south- western Burkina Faso, West Africa. This area is based on sheared and metamorphosed greenschist facies rocks. Metamorphism locally reaches to the amphibolite facies around intrusions. There are two major lithological units whose interface is marked by a NW-SE trending shear corridor: an unit of andesite-basaltic rocks of andesitic breccias in the East and volcaniclastic and sedimentary unit composed flows, tuffs and felsic to mafic breccia, interbedded volcano-sedimentary rocks. All this together is intruded by plutonic rocks, and various felsic to mafic dykes. These rocks have undergone ductile to brittle heterogeneous deformations and hydrothermal alteration sericite ±carbonate ±quartz±sulphide within deformation corridors. The rocks of the East and West domains affected by three phases of brittle-ductile deformation (D1, D2, and D3) and the meteoric alteration is systematic in superficial facies of Djarakadougou core drilling.Geochemical analysis shows a tholeiitic to calc-alkaline volcanic serie characteristic a bimodal volcanism. The spectra of normalized REE chondrites are generally flat and constant reminding those of N-MORB basalt. The chemical compositions of andesite and basalt are deferred on several discrimination diagrams especially Th / Yb - Nb / Yb and 2 Nb - Zr / 4 - Y show that andesites and basalts of the prospect are issued in geotectonic setting of volcanism preponderant arc.

The history of the Black Volta region in what is currently south-west Burkina Faso and north-west Ghana has been marked by the agricultural expansion of Dagara-speaking groups. This article explores how and why these groups were able to expand at the expense of neighbouring segmentary societies such as the Phuo and the Sisala. Violence certainly played a role in their territorial expansion, but so did specific strategies of ritual appropriation of new territories. The Dagara system, with its characteristic fission of existing earth shrines and networks of interlinked shrines, allowed mobility and helped the migrants bring new territories under their ritual control. In addition, patriclans and matriclans as well as joking relationships, clan alliances and institutionalized friendship enabled the Dagara pioneers to recruit many new settlers within a short time. This was a crucial asset for the security of the newly founded settlements and the territorial encroachment on Phuo and Sisala lands. In addition, mobility was, and continues to be, supported by an explicit ethos of independence and autonomy. Focusing on the late pre-colonial periods, the article looks at different stages of Dagara expansion and the changing interethnic relations.

Abstract Background To eliminate lymphatic filariasis (LF), since 2001, Burkina Faso adopted a community-based treatment with annual mass drug administration (MDA) of ivermectin-abendazole. However, after more than 11 rounds of MDA, it remained some hotpots where transmission is still being active. Therefore, to better scale up elimination measures toward 2030, it seems necessary to assess the prevalence of Wuchereria bancrofti both in human and vector populations. Methods Parasitological and entomological surveys were conducted in August 2014 and in September 2015, in six hotpots areas dispersed in Centre-East, East and South-West health regions for blood and vector’s collections. Nocturnal finger-prick blood samples and microscopic observations were performed to determine the prevalence of W. bancrofti in humans. Mosquitoes were collected by human landing catches and indoor spraying collections. They were identified morphologically and those of the Anopheles gambiae s.l. were confirmed by PCR. Then the W. bancrcofti prevalence within such vector populations was determined by conventional and LAMP PCR technique using the DNA of pooled mosquitoes grouped by species. Results The results highlighted the persistence of W. bancrofti infection both in human and vector populations after multiple rounds of MDA in the sites. The prevalence of W. bancrofti in human populations was reduced in 2015 compared to 2014. Within the An. gambiae s.l., only An. coluzzii was found infected by W. bancrofti respectively in Centre-East and East health regions, whereas An. nili was the most infected vector in Saptan in the South-West health region. Some specimens of An. funestus s.l. were tested positive to W. bancrofti with the LAMP PCR but failed to be confirmed by the conventional technique. Conclusions Despite the MDA campaigns supplied by vector control interventions relied on the mass coverage of insecticide treated nets, the incidence of LF is still effective in these hotspots but luckily in decreasing trend. The novelty is that An. nili was found infected by W. bancrofti that increased the number of potential vectors of W. bancfrofti in Burkina Faso.

Trees And Shrubs

Leafing, flowering and fruiting of the 24 most representative species of trees and shrubs in Sudanian savannas and fallows near Bondoukuy (Burkina Faso) were studied for 2 y (May 1992 to June 1994). The period of defoliation was generally brief, and leaf flushing, flowering and fruiting occurred mostly in the dry season. The phenological behaviour varied nonetheless across species and individuals. A classification taking into account synchrony/asynchrony and duration in foliation, flowering, fruit ripening and seed dispersal phases allowed comparison of species' phenological plasticity. Species were distributed along a scale of increasing plasticity, from trees to shrubs. Along this scale, species of the Leguminosae appeared to be separated from those of the Combretaceae, the latter being generally considered as characterising fallow farming systems. These results provide new evidence about the effect of phylogenetic constraints on the phenological behaviour of the woody species of the Sudanian savannas.RÉSUMÉ. La feuillaison, la floraison et la fructification des 24 espèces d'arbres et d'arbustes les plus représentatives des jachères et savanes soudaniennes de la région de Bondoukuy (Burkina Faso), ont été étudiées pendant 2 ans (mai 1992 à juin 1994). La défeuillaison est généralement brève et l'émergence des feuilles, la floraison et la fructification se produisent principalement pendant la saison sèche. Les comportements phénologiques varient cependant entre les individus et entre les espèces. Une classification prenant en compte le degré de synchronisme ainsi que la durée de la feuillaison, de la floraison, de la maturation des fruits et de la dispersion des graines a permis de comparer la plasticité phénologique des espèces. Celles-ci sont distribuées selon un gradient de plasticité croissante des arbres aux arbustes. Sur ce gradient les Légumineuses se dissocient des Combrétacées, espèces qui sont par ailleurs généralement considérées comme caractéristiques des jachères. Ces résultats sont une nouvelle illustration de l'effet des contraintes phylogénétiques sur le comportement phénologique des espèces ligneuses des savanes soudaniennes.
