Though the study of metrics and poetic verse has long informed phonological theory, studies of musical adaptation remain on the fringe of linguistic theory. In this paper, I argue that musical adaptation provides a unique window in speakers’ knowledge of their phonological system, which can provide crucial evidence for phonological theory. I draw on two case studies from my fieldwork in West Africa: tonal textsetting of sung folk music in Tommo So (Dogon, Mali) and the balafon surrogate language in Seenku (Mande, Burkina Faso). I show how results of these studies provide evidence for different levels of phonological grammar, the phonetics-phonology interface, and incomplete application of grammatical tone. Further, the case of the balafon surrogate language shows how studying music can be a valuable tool in language documentation and phonological description. Finally, preliminary study of Seenku tonal textsetting suggests important differences in the level of phonological encoding in vocal music vs. instrumental surrogate speech.

In this article we bring anthropological reflections to bear on a recent event we participated in, whereby farmers and scientists came together to discuss the possibility of applying rainfall seasonal forecasts to improve agricultural production and livelihood security in West Africa. In so doing, We also report on the research findings from the project that organized this encounter and that we have been working with for the last three years. Our intent is to highlight the complexities and challenges inherent in this process of integrating scientific information and farmers' production decisions, while also pointing to practical issues to be considered in implementing such initiatives.

Les graines de néré (Parkia biglobosa) sont transformées traditionnellement en Afrique de l’Ouest en des condiments fermentés sous différentes appellations : soumbala au Burkina Faso, nététu au Sénégal, soumbara en Guinée Conakry, dawadawa et iru au Nigéria, afitin, iru et sonru au Bénin. Ces produits sont caractérisés par la variabilité de leur qualité et des contraintes liées à leur production. La présente revue a pour objectif d’analyser les technologies traditionnelles utilisées pour la production de ces condiments fermentés à base de graines de néré et de faire ressortir les contraintes/difficultés de production de ces condiments. Les données ont été collectées à travers les documents physiques consultés (thèses et mémoires) et à partir des articles scientifiques et d’autres documents trouvés en ligne. Il en résulte que les technologies de production traditionnelle des condiments à base de graine de néré en Afrique de l’Ouest, incluent principalement selon les zones et les ethnies, une première cuisson des graines allant de 12-48 h, un décorticage manuel des graines cuites, une seconde cuisson des graines décortiquées et lavées variant de 1-4 h et enfin, une fermentation des cotylédons cuits allant de 24-120 h. Ces technologies ont également en commun, des contraintes majeures de pénibilités du processus de cuisson, du décorticage/lavage, de la consommation importante d’énergie, d’eau et de temps. Les données de cette revue ouvrent ainsi de nouvelles pistes de recherche pour l’amélioration des procédés traditionnels de transformation des graines de néré.

R.Br.) en Afrique de l’Ouest : revue des principaux produits dérivés et contraintes de production 15699 Traditional technologies for processing African locust bean seeds (Parkia biglobosa Jacq. R.Br.) in West Africa: review on the main derivatives and production constraints. ABSTRACT African locust bean (Parkia biglobosa) seeds are traditionally transformed in West Africa into fermented condiments under different names: soumbala in Burkina Faso, netetu in Senegal, soumbara in Guinea Conakry, dawadawa and iru in Nigeria, afitin, iru and sonru in Benin. These products are characterized by the variability of their quality and the constraints linked to their production. The objective of this study is to analyze the traditional technologies used for the production of these fermented condiments and to highlight the constraints/difficulties associated to their production. The data were collected through the physical documents consulted (theses and dissertations) and from scientific articles and other documents found online. It appear that the traditional technologies used to produce P. biglobosa seeds based-condiments in West Africa, mainly include, according to the zones and ethnic groups, a first cooking of the seeds ranging from 12-48 h, a manual dehulling of the cooked seeds, a second cooking of the dehulled and washed seeds varying from 1-4 h and finally, a fermentation of the cooked cotyledons ranging from 24-120 h. These technologies have in common the major constraints of hardness of the process of cooking and dehulling/washing, significant consumption of energy, water and time. Data from this review opens research perspectives for the improvement of the traditional processing of P. biglobosa seeds. Keywords: P. biglobosa seeds, condiment, soumbala, process.

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.
