GRACE satellite gravity data was used to estimate mass changes within the Volta River basin in West African for the period of January, 2005 to December, 2010. We also used the precipitation data from the Tropical Rainfall Measurement Mission (TRMM) to determine relative contributions source to the seasonal hydrological balance within the Volta River basin. We found out that the seasonal mass change tends to be detected by GRACE for periods from 1 month in the south to 4 months in the north of the basin after the rainfall events. The results suggested a significant gain in water storage in the basin at reference epoch 2007.5 and a dominant annual cycle for the period under consideration for both in the mass changes and rainfall time series. However, there was a low correlation between mass changes and rainfall implying that there must be other processes which cause mass changes without rainfall in the upstream of the Volta River basin.

Globally 390 millions of people are at risk of dengue infection; over the past 50 years the virus incidence increased thirty-fold. In Senegal, an unprecedented occurrence of outbreaks and sporadic cases was noticed since 2017. In October 2018 an outbreak of DENV-2 was reported in Rosso area in the north of Senegal at the border with Mauritania. Out of the 187 blood specimen samples collected, 27 were positives by qRT-PCR and 8 were serologically positive for DENV IgM. Serotyping using qRT-PCR reveals that isolates were positive for DENV-2. A subset of DENV-2 positives samples was selected and subjected to full genome sequencing followed by phylogenetic analysis. Analysis of 06 nearly completed genome sequences (n= 6) revealed that isolates belong to the cosmopolitan genotype and are closely related to the Mauritanian strains detected between 2017 and 2018 and those detected in many West African countries such as Burkina Faso or Cote d’Ivoire. Our results suggest a transboundary circulation of the DENV-2 cosmopolitan genotype between Senegal and Mauritania and call for a need of coordinated surveillance of arboviruses between these two countries. Interestingly, high level of homology between West African isolates highlights endemicity and call for a set-up of sub-regional viral genomic surveillance which will lead to a better understanding of viral dynamic, transmission and spread across Africa.

American Diplomacy

This chapter analyses the British naval policies concerning West Africa between 1843 and 1857. During this period, Britain sought to encourage legitimate commerce and curtail slavery for its own economic interest, while domestically America feared the British domination of the West African coast. As such, suspicion and mistrust was rife between the two nations, and is in great detail via the abolitionist activity in the North of England; the actions of free traders and slavers; Royal Navy operations; the competition for trade between Britain and France; Commodore Charles Hotham’s slavery suppressing naval strategy; British free trade treaties; and the naval methods of enforcing British goals. It concludes in 1857, with British interests torn between strategic naval aims and domestic pressures, and British and American diplomacy still tense over West African policies.

General Regression

Paleogeographic reconstructions of Paleozoic time are presented for the northwest margin of the West-African Craton. An extensional regime and a marine transgression were dominant during the Early Cambrian. During the Middle Cambrian, the Rokélides orogen was responsible for the sea regression to the south, while the proto-Atlantic opening was active to the north of the Reguibat shield. A large stable marine platform was present during Early and Middle Ordovician. A general regression and the formation of the West-African Inlandsis took place during the Late Ordovician. During Silurian time, this sea transgressed over most of the African platform. Incipient Hercynian deformations during the Early Devonian produced horsts and grabens in Morocco. At the end of the Devonian and the beginning of the Carboniferous, the sea was restricted to isolated basins and tectonic trenches. Collision between West Africa and North America during the Late Carboniferous transformed the Lower Paleozoic margin into an Hercynian orogenic belt, whose structure is controlled by the presence of crustal blocks, generated as early as the Cambrian, and probably reflecting, in turn, older Panafrican zones of weakness.

Abstract New geodynamical data from West Africa bring consistent informations on the pre-Mesozoic reconstruction within a large area running from the western Sahara to the Colombian cordillera. These new data support a Neoproterozoic Ocean (WANO) between the Amazonian (AMC) and West African (WAC) cratons previously to the Iapetus and Rheic oceans. We delineate 31 blocs detached from the surrounding three continents: NAC (North American Craton), AMC and WAC. 7 came from the WAC margin, 7 from the NAC, 6 from the AMC and 11 from an intermediate volcano sedimentary domain (COB) built on a 1200–1000 Ma oceanic crust. These imbricated blocks formed a tight mosaic by the Hercynian/Alleghanian tectonic event which gave way to the Pangea super-continent. But, during the Atlantic Ocean opening these blocks began to move. They were separated by new oceanic basins. However, previously to the Pangea, blocks from the COB domain formed two sets of garlands located on the northwestern Gondwana margin. The northern one moved to the North until the Silurian to collide the NAC (Taconic tectonic event) meanwhile the southern one remains on the Gondwana margin. All together were gathered by the Carboniferous/Permian time. Then, the framework for the opening of the Atlantic Ocean was not totally disconnected from the “Variscan” collage and many variscan weakness zones were re-used as initial breaking zones. Beyond this tectonic impact, the pre-mesozoic assemblage allows us to compare this “Caribbean” island arc with another one: the Indonesian “Banda” arc. Thus, West Africa is a geological key area for correlations between the Caribbean, the Appalachian, the Brazilian “Nordeste” and the West European domains and for the understanding of the Atlantic Ocean opening process.

This chapter briefly charts the emerge of the violent Islamist group Boko Haram in Nigeria before detailing its international connections and interactions with Al-Qaeda and, more significantly, Al-Qaeda in the Islamic Maghreb (AQIM). It goes on to discuss the group’s successful attempts at territorial control in the north east and its leader’s ambition to establish an Islamic state. The text explains how the Nigerians converged with ISIS, pledged allegiance to Abu Bakr al-Baghdadi and rebranded Boko Haram as Islamic State West African Province (ISWAP). This is complemented by an analysis of the practical manifestations of this allegiance, the remaining differences between ISWAP and ISIL/ISIS, and the possibly opportunistic reasons that may have motivated this move and that, in the future, could make the Nigerian outfit look elsewhere for more productive partnerships.

The Doors of the Chapel and the Keys to the Palace of Louis IX considers two virtually unknown sculpted portals located in the second bay on the north side of the Sainte-Chapelle, the monumental reliquary chapel built by Louis IX in the royal palace of Paris between 1239 and 1248. Examining archaeological and archival documentation concerning these portals, Meredith Cohen provides important new insights about the initial design and function of the Sainte-Chapelle, its attendant structures, and the royal palace. After charting the history of the Chevesserie, the building to which the portals issued, Cohen proposes a relative chronology for the other structures in the palace attributed to Louis IX, arguing that construction of the Sainte-Chapelle generated major changes, which defined the palace as symbol of the royal state starting in the thirteenth century. This article contributes to the research in medieval architecture that views great monuments as part of highly complex historical topographies.

Length composition, maturation and growth of the ommastrephid squid Todaropsis eblanae were studied using length–frequency distributions (LFDs) and statoliths of squid caught off the north-west African coast. Length–frequency distributions were quite similar in all seasons studied, indicating all year round spawning. However, both high proportions of mature squid in the winter and the hatching peak of squid from our sample in spring suggested the winter–spring peak of spawning. Immature and maturing squid had rather high growth rates, attaining 140—150 mm of dorsal mantle length (ML) by the age of 160—170 d. Todaropsis eblanae is likely to have an annual life cycle on the north-west African shelf.
