The composition and performance of Arabic Sufi poetry is the most characteristic artistic tradition of West African Sufi communities, and yet this tradition has yet to receive the scholarly attention it deserves. In this article, I sketch an outline of a theory of Sufi poetics, and then apply this theory to interpret a performance of a popular Arabic poem of the Senegalese Shaykh Ibrahim Niasse (d. 1975), founder of the most popular branch of the Tijāniyya in West Africa.

It is gratifying to receive compliments when one publishes books, yet I have mixed feelings about some of the kind words awarded to my two volumes of translations from seventeenth-century German sources on west Africa. What some people seem to be saying is: “Thank God I won't have to waste time learning that language!” Not only does this attitude rest on the untenable assumption that a translation is an adequate substitute for the original; it also underestimates the importance of those German works which remain untranslated.For those interested in the colonial period, of course, the German literature and archival material is very rich--not only for Togo and Cameroun, but also for other countries, notably Liberia. As soon as the Germans became politically involved in west African affairs in 1884, there appeared a whole flood of publications dealing with this part of the world; and there is also a great deal of unpublished material for the whole period 1884-1939 which urgently calls for more attention from scholars interested in the African past. This is generally recognized (the usual excuse offered for not using the German material is the difficulty of access to the Potsdam archive); yet it is seldom appreciated how much German material there is for the period before 1884.

This chapter examines the politics of the currency in West Africa from the beginning of the twentieth century. A public series of debates over the nature of the currency occurred in West Africa during both the colonial and independence periods. Since 1983, West African countries have been pioneers in Africa in developing new strategies to combat overvaluation of the currency and reduce the control of government over the currency supply. The chapter charts the evolution of West African currencies as boundaries and explores their relationship to state consolidation. It shows that leaders in African capitals managed to make the units they ruled increasingly distinct from the international and regional economies, but the greater salience of the currency did not end up promoting state consolidation. Rather, winning the ability to determine the value of the currency led to a series of disastrous decisions that severely weakened the states themselves.

Abstract The positioning technique employing the ubiquitous signals of opportunity of non-cooperative satellites does not send special navigation signals, instead it passively receives satellite signals as noise, presenting advantages of concealment and difficulty for potential attackers. Thus, this study investigates the ranging principle and model using non-cooperative communication satellites and a time difference estimation algorithm. The technology of time difference measurement under non-cooperative observation mode was determined and simulated. A test platform for time difference measurement was built to receive the signal from an unknown geostationary Earth orbit communication satellite and verify the ranging feasibility and performance. The ranging accuracy was found to be smaller than 6 m, as demonstrated by experimental data, which shows the viability of the proposed positioning technique for ranging technology.

Abstract. The Pliocene is regarded as a potential analogue for future climate with conditions generally warmer-than-today and higher-than-preindustrial atmospheric CO2 levels. Here we present the first orbitally resolved records of continental hydrology and vegetation changes from West Africa for two Pliocene time intervals (5.0–4.6 Ma, 3.6–3.0 Ma), which we compare with records from the last glacial cycle (Kuechler et al., 2013). Our results indicate that changes in local insolation alone are insufficient to explain the full degree of hydrologic variations. Generally two modes of interacting insolation forcings are observed: during eccentricity maxima, when precession was strong, the West African monsoon was driven by summer insolation; during eccentricity minima, when precession-driven variations in local insolation were minimal, obliquity-driven changes in the summer latitudinal insolation gradient became dominant. This hybrid monsoonal forcing concept explains orbitally controlled tropical climate changes, incorporating the forcing mechanism of latitudinal gradients for the Pliocene, which probably increased in importance during subsequent Northern Hemisphere glaciations.

In the following article is described an interesting parasitic condition which is difficult to interpret. The small intestine of an Hadada, Geronticus hagedash, was brought back from the West Coast of Africa by Major T. A. Cockburn, M.D., R.A.M.C, who kindly passed it to me for further examination. The bird is a member of the family Plataleidae, living in wooded districts in West Africa in the neighbourhood of water and feeding on invertebrates, mainly annelids and small crustaceans which it finds at the bottom of ponds and streams in the mud.

Abstract Accurate prediction of the commencement of local rainfall over West Africa can provide vital information for local stakeholders and regional planners. However, in comparison with analysis of the regional onset of the West African monsoon, the spatial variability of the local monsoon onset has not been extensively explored. One of the main reasons behind the lack of local onset forecast analysis is the spatial noisiness of local rainfall. A new method that evaluates the spatial scale at which local onsets are coherent across West Africa is presented. This new method can be thought of as analogous to a regional signal against local noise analysis of onset. This method highlights regions where local onsets exhibit a quantifiable degree of spatial consistency (denoted local onset regions or LORs). It is found that local onsets exhibit a useful amount of spatial agreement, with LORs apparent across the entire studied domain; this is in contrast to previously found results. Identifying local onset regions and understanding their variability can provide important insight into the spatial limit of monsoon predictability. While local onset regions can be found over West Africa, their size is much smaller than the scale found for seasonal rainfall homogeneity. A potential use of local onset regions is presented that shows the link between the annual intertropical front progression and local agronomic onset.

This paper draws attention to an ambitious project in the publication of source material for the precolonial history of West Africa, which has recently been approved for inclusion in the Fontes Historiae Africanae series of the British Academy. In addition to self-promotion, however, I wish also to take the opportunity to air some of the problems of editorial strategy and choice which arise with regard to the editing and presentation of this material, in the hope of provoking some helpful feedback on these issues.The material to be published consists of correspondence of the Royal African Company of England relating to the West African coast in the late seventeenth century. The history of the Royal African Company (hereafter RAC) is in general terms well known, especially through the pioneering (and still not superseded) study by K.G. Davies (1957). The Company was chartered in 1672 with a legal monopoly of English trade with Africa. Its headquarters in West Africa was at Cape Coast (or, in the original form of the name, Cabo Corso) Castle on the Gold Coast, and it maintained forts or factories not only on the Gold Coast itself, but also at the Gambia, in Sierra Leone, and at Offra and Whydah on the Slave Coast. It lost its monopoly of the African trade in 1698, and thereafter went into decline, effectively ceasing to operate as a trading concern in the 1720s, although it continued to manage the English possessions on the coast of West Africa until it was replaced by a regulated company (i.e., one open to all traders), the Company of Merchants Trading to Africa, in 1750.

<p>The West African Craton (WAC) is one of the major cratons in the Rodinia jigsaw puzzle (~1000–750 Ma). In the Rodinian models, the position of West Africa is mainly constrained by the assumption that it had been a partner of Amazonia since the Paleoproterozoic. Unfortunately, no paleomagnetic data are available for these cratons when the Rodina supercontinent is considered tectonically stable (~1000-750 Ma). Thus, every new reliable paleomagnetic pole for the West African Craton during the Neoproterozoic times is of paramount importance to constrain its position and testing the Rodinia models. In this study we present a combined paleomagnetic and geochronological investigation for the Manso dyke swarm in the Leo-Man Shield, southern West Africa (Ghana). The ~860 Ma emplacement age for the NNW-trending Manso dykes is thus well-constrained by two new U-Pb apatite ages of 857.2 ± 8.5 Ma and 855 ± 16 Ma, in agreement with baddeleyite data. Remanence of these coarse-to-fine grained dolerite dykes is carried by stable single to pseudo-single domain (SD-PSD) magnetite. A positive baked-contact test, associated to a positive reversal test (Class-C), support the primary remanence obtained for these dykes (13 sites). Moreover, our new paleomagnetic dataset satisfy all the seven R-criteria (R=7). The ~860 Ma Manso pole can thus be considered as the first key Tonian paleomagnetic pole for West Africa. We propose that the West Africa-Baltica-Amazonia-Congo-São Francisco were associated in a long-lived WABAMGO juxtaposition (~1100–800 Ma).</p><p><strong>Keywords:</strong> West Africa, Neoproterozoic, Tonian, Rodinia, paleomagnetism.</p><p> </p>
