Résumé :

Since 2015, the European Union has stepped up its efforts to curb irregular migration from sub-Saharan Africa through increasingly restrictive measures targeting transit countries along migratory routes, including Niger. While the EU has heralded the success of its policies to limit migration through Niger, EU migration policies have disrupted the economic system in Agadez, where transit migration has been one of the main sources of income and a factor of stability since the end of the Tuareg rebellions in 2009. This article discusses the impact that EU migration policies may have at the local level in countries of transit, and highlights the potential for these policies to fuel tensions between local and national authorities. The Agadez case study illustrates the importance of a multilevel approach to migration governance that takes into full consideration the role of local authorities and local communities in countries of transit.

Résumé :

Coal is the most widely available fossil fuel energy resource. This work was carried out to compare the composition, Sulphur content and combustibility of the Nigerian and Nigerien coal samples. Coal samples were obtained from Enugu, Nigeria, Tahuoa and Agadez of Niger Republic. Results indicated that, coal samples from Tahuoa (RS/T) and coal from Agadez (RS/A) have highest percentage of fixed carbon (71.2% and 61.0% for Tohoua and Agadez respectively), while the coal from Enugu (RS/E), Nigeria, have the least percentage (49.2%) which made them to have high fuel ratio enabling them to be more combustible, as determined by the thermal efficiency test. The study revealed that the coal from Niger is of higher grade with ease of combustion and less smoke as found in the combustibility test. Keywords: Coal, Sulphur, fuel ratio, carbon content, combustion and thermal efficiency.

Résumé :

Abstract:This article focuses on the texts known as the “Agadez Chronicles” and “Y Tarichi,” which have been used by historians of the Central Sahara and Sahel to reconstruct the history of the Sultanate of Agadez and the Ader Kingdom in today’s Republic of Niger. The most frequently cited of these texts are published translations of copies of Arabic manuscripts that were made available to French and British colonial administrators by members of the elites of Agadez, Ader, and Sokoto in the first decade of the twentieth century. This article suggests that the copies handed over to the representatives of European empires had been altered to promote the interests of the local elites who circulated these sources. The article compares texts in the Agadez corpus with independent sources on the history of this region in the fifteenth, sixteenth, and seventeenth centuries; it discusses the political context in which the Agadez Chronicles were circulated at the beginning of the twentieth century; and it considers the implications of the proposed reinterpretations for the historiography of the Aïr and Ader regions.

Résumé :

Petrified footprints of now extinct rhinos and those of humans in the mud of the former lake Agadem may symbolise the beginning of an epoch dominated by humans. How could such a “local” Anthropocene be defined? In eastern Niger, two aspects seem particularly important for answering this question. The first is the disappearance of the addax in the context of the megafauna extinction. The second is the question how the “natural” environment may be conceived by the local Teda where current Western discussions highlight the “hybridity” of space.

Résumé :

Some physicochemical (insoluble content, ionic composition, density, and X-ray diffraction spectra) characteristics of Nigerien evaporites were investigated in this study. The results obtained showed that trona is the main mineral contained in Agadez, Dirkou, Niamey, and Zinder evaporites while thenardite and halite constitute the major minerals in Bilma and Tabalak evaporites, respectively. In addition, all evaporites samples investigated revealed the presence of quartz and halite. Other interesting minerals (calcite, gypsum, sylvite, aphthitalite, nahcolite, illite, burkeite, kaolinite, griceite, and talc) were also detected. The use of Agadez, Dirkou, Niamey, and Zinder evaporites as catalyst to accelerate cowpea cooking is due to bicarbonates ions present in trona. Bilma and Tabalak evaporites employed in animal feeding are due to the halite contained in a significant quantity.

Résumé :

This study was carried out to assess administrative strategies for enhancing Peace Education (PE) in 29 Junior Secondary Schools in the region of Agadez, Niger Republic. The study was descriptive. Quantitative and non- parametric data that helped determine majority views were collected, tallied, converted into simple percentages and means using a calculator. Information from documents that were initially in French was translated into English. The research used a total population of 487 teachers and school administrators from 29 Junior Secondary Schools in the region of Agadez. All the 84 administrators from the 29 Junior Secondary Schools were included in the research as their number was small; 388 teachers were sampled out of 403 using the Research Advisors’ Sample Size Table and Simple Random Technique. The research instrument was a self-designed structured questionnaire titled Administrative Strategies for Enhancing Peace Education Questionnaire, which was validated and had a reliability index of .75. This paper dealt with the curriculum content that could enhance Peace Education in Junior Secondary Schools in the region of Agadez. The findings revealed that the Peace Education curriculum content was scanty. The study recommended, among others, that the Junior Secondary Schools Peace Education curriculum should be revised, and should therefore encompass relevant issues that would mould the students’ minds, issues that would help them to learn to live together and enhance mutual understanding in community; to this end, the Peace Education curriculum should mainstream Human Rights Education, Conflict Resolution Education, Disarmament Education, Development Education, International Education, Civics and any other type of education that is likely to bar the students from getting involved in violent conflict or even terrorism.

Résumé :

The present study attempts to analyze the relationship between the use of ICT on the one hand and the performance of master students (future primary school teachers) on the other hand. A sample of 400 master students from the teacher training colleges of seven (7) administrative regions of Niger (Tillabery, Niamey, Dosso, Maradi, Zinder, Tahoua and Agadez) was selected. Data were collected using a questionnaire and the government's logbook. It has been postulated that the use of ICT by masters’ students, outside normal class hours, improves performance, both in terms of the annual average of students and practical internship grades preparing them for the teaching profession. The results indicate that 92% of respondents say that ICT improves their academic performance. However, the statistical analysis does not show a significant difference between the performances of those who use ICT outside their normal hours and those who do not use them.

Résumé :

Nel Sahara, i migranti africani lungo la loro strada per la Libia o l'Europa sviluppano una forma specifica di territorialitŕ basata sulla paura della "diversitŕ" e dell'"esterioritŕ" dell'ambiente geografico che transitano. Le costruzioni territoriali che sono il risultato di questo contribuiscono alla trasformazione del modo in cui tali spazi di transito funzionano cosě come alle attivitŕ che hanno luogo in queste oasi e le infrastrutture che emergono come risposta al crescente traffico trans-sahariano. L'analisi della territorialitŕ e della socialitŕ dei migranti durante il loro arrivo e permanenza in Agadez e durante il loro passaggio successivo attraverso l'Erg del Ténéré permette di studiare come i flussi migratori che passano attraverso il Sahara lasciano la loro imprint socio-spaziale su queste oasi di transito.

Résumé :

This study examines the impacts of relevant factors (climatic and nonclimatic) on the monthly electricity consumption (MEC) in four major cities in Niger using simple multiple linear regressions (MLRs). Parameters such GDP/capita, air temperature (Tmean), relative humidity (RH), wind speed (WSP), solar radiation (SR), precipitation, and clearness index (K) are used. In addition, two heat indices, heat index (HI) and discomfort index (DI) are calculated to take into account the impacts of high humidity in conjunction with high ambient temperature. Hence, three different models were derived from the aforementioned variables. The three models have been tested using the k-folds cross-validation. Results show that the model with primitive variables such GDP per capita, Tmean, RH, SR, and WSP perform better than the other two models with a coefficient determination R2 equal to 0.87, 0.854, 0.833, and 0.551 for Niamey, Maradi, Zinder, and Agadez, respectively. According to the month considered, the mean absolute percentage error can give a small error for specific combinations of climate variables. The variables such as precipitation and clearness index are found to be not statistically significant.

Résumé :

Berber (or Tamazight) is an Afro-Asiatic language spoken by an estimated 15–25 million in North Africa. It is mainly spoken in Morocco, Algeria, and by the Touareg population in Niger and Mali. Berber is also a native language of populations living in Libya, Tunisia and Egypt, though their numbers are less significant. Large Berber communities also live in Diasporas mainly in France, Spain, Holland, and Belgium. Three varieties of Berber are spoken in Morocco: Tarifit, spoken in northern Morocco, Tamazight, spoken in the Middle-Atlas, and Tashlhiyt, spoken in southern Morocco. Tashlhiyt, the variety presented here, is sufficiently homogeneous for all native speakers, who number an estimated 7–9 million, to communicate without difficulties (Stroomer 2008). There is nonetheless a measure of sub-dialectal variation, which affects mainly the way some stop consonants are produced. Three subsystems, corresponding roughly to three distinct geographical locations, can be identified: the ‘occlusive’ subsystem spoken in Agadir and its suburbs, the ‘fricative’ subsystem spoken mainly in the High-Atlas area, which spirantizes noncoronal obstruents /bkg/ in some contexts, and the ‘sibilant’ subsystem spoken in the Anti-Atlas area, where /t/ and /d/ are realized in some contexts as [s] and [z], respectively (Boukous 1994). This study is based on the speech of Tashlhiyt speakers who originate from Agadir. The text of ‘The North Wind and the Sun’ was read by a 27-year-old female speaker.

Résumé :

The present study conducted in the northern zone of Niger aims to show the impact of land use dynamics on woody vegetation. The methodological approach consisted in making in addition to the floristic surveys, the analysis of land use maps (LANDSAT images of the years 1975 and 2018). The floristic inventory allowed the identification of twenty-seven (27) woody species of which eleven (11) in Tanout and sixteen (16) in Aderbissinat. The most important families remain the Fabaceae-Mimosoideae which represent 37.5% at Aderbissinat and 45.45% at Tanout. The biological types remain dominated by microphanerophytes which dominate (86.67%), while for the phytogeographic types it is the Sudano-Zambezian and Sudanian species that dominate, with proportions respectively equal to 31.25%. There is a regression of woody vegetation at the level of these communes with a slight loss in Aderbissinat (60588,034 ha) and an accentuated degradation of vegetation in Tanout (781797,738 ha).

Résumé :

The Paleogene Sokor1 Formation in Termit Basin is recognized as the most important hydrocarbon reservoir. However, in spite of its reservoir importance, published studies on its diagenetic process and their effects on reservoir quality are absent or limited. Petrographic analysis, scanning electron microscopy and X-ray diffraction were used to assess diagenetic characteristics, controls on reservoir and reservoir quality of Sokor1 Formation. The Sokor1 sandstones are mostly quartz sandstone, lithic quartz-arenite and rarely lithic fedspathic-quartz-arenite, with an average mass fraction of quartz 95%, feldspar 1.6% and rock fragments 3.4% (Q95F1.6R3.4). Diagenetic processes in Sokor1 sandstones include mechanical compaction, cementation, dissolution and replacement. The main authigenic minerals are quartz overgrowth and clay minerals, which occur as pore-filling and pore-lining cements. Sokor1 sandstone has undergone stages A and B of eodiagenesis and now, it is experiencing stage A of mesodiagenesis. The widespread occurrences of quartz overgrowth suggest that Sokor1 sandstones lost a significant amount of primary porosity during its diagenetic history. Secondary porosity occurred due to partial and complete dissolution of feldspar, quartz grains and rock fragments, so increasing reservoir quality. The latter is predominantly controlled by depositional environment controls on grains size, sorting and matrix. Thus, reservoirs of best quality were deposited in braided river channel environments. In addition, oil accumulation has no discernable effects on porosity and oil probably entered the reservoir at late diagenetic stage, after quartz overgrowth and authigenic cements had already occurred.

Résumé :

Le cheptel camelin est tributaire des ressources fourragères des parcours naturels dont le développement est soumis aux aléas de la pluviométrie, très mal repartie dans le temps et l’espace. Pour exploiter ces parcours, l’une des stratégies adoptée par les éleveurs est la mobilité. Cependant, depuis un certain temps, les mutations climatiques, socio-économiques et les conditions d’une urbanisation accélérée imposent de plus en plus des changements dans la règle de gestion des élevages. Le développement à Agadez d’une minilaiterie, dont l’activité principale est centrée essentiellement sur la transformation du lait de chamelle, nécessite la connaissance parfaite du fonctionnement des élevages laitiers qui vont approvisionner cette laiterie. Une enquête a été menée durant deux mois auprès de cent élevages camelins de la zone périurbaine d’Agadez en vue de connaître le fonctionnement des élevages de cette zone. L’analyse des données recueillies sur les pratiques de gestion de troupeaux et le fonctionnement global des élevages des pasteurs chameliers ont permis de distinguer trois grands types d’élevages, différenciés essentiellement sur la base des pratiques d’alimentation des animaux et sur la mobilité des pasteurs. A cela s’est ajoutée une affinité zonale de certains éleveurs, dont les causes sont sociohistoriques et écologiques. Le premier groupe de pasteurs avait la particularité d’être sédentaire, d’avoir un troupeau de taille moyenne et de pratiquer la complémentation et la spéculation laitière. Le deuxième groupe pratiquait fortement la transhumance en saison des pluies et certains d’entre eux complémentaient les animaux. La vente du lait de chamelle était quasi inexistante pour ces pasteurs. Les chameliers composant le troisième groupe avaient de grands troupeaux et pratiquaient en conséquence un nomadisme régulier. Par les contacts particuliers établis par certains producteurs de ce groupe avec la laiterie, la vente de lait était de plus en plus pratiquée. La taille, la composition des troupeaux, les ressources fourragères et hydrauliques constituaient les principaux facteurs déterminants des déplacements des éleveurs.

Résumé :

Abstract. The Sahel is the semi-arid transition zone between arid Sahara and humid tropical Africa, extending approximately 10–20° N from Mauritania in the West to Sudan in the East. The African continent, one of the most vulnerable regions to climate change, is subject to frequent droughts and famine. One climate challenge research is to isolate those aspects of climate variability that are natural from those that are related to human influences. Therefore, the study of climatic conditions before mid-19th century, when anthropogenic influence was of minor importance, is very interesting. In this work the frequency of extreme events, such as droughts and floods, in Western Sahel from the 16th to 18th centuries is investigated using documentary data. Original manuscripts with historical chronicles from Walata and Nema (Mauritania), Timbuktu and Arawan (Mali), and Agadez (Niger) have been analyzed. Information on droughts, intense rainfall, storms and floods, as well as socioeconomic aspects (famines, pests, scarcity, prosperity) has been codified in an ordinal scale ranging from −2 (drought and famines) to +2 (floods) to obtain a numerical index of the annual rainfall in the region. Results show wet conditions in the 17th century, as well as dry conditions in the 18th century (interrupted by a short wet period in the 1730s decade).

Résumé :

While varying factors have been adduced as facilitators of budding patterns of irregular mobility across the Sahara, a pivotal issue of concern amid the crisis has been lack of appropriate gender profiling of various actors. Engaging an exploratory design (which combines case profiling, in-depth interviews [IDIs], and focus group discussions [FGDs]) and ‘actor-network’ theoretical approach, which affirms the significance of both human and nonhuman agencies in processes of irregular transnational mobility, this study assesses the interpositions of gender and migrants’ smuggling along the Nigerian–Libyan migratory corridor. Although organized crime is explored as a general notion, the emphasis in the study has been on specific gender roles of individual actors (between the point of migrants’ departure [Benin City, Nigeria] and the point of migrants’ processing [Agadez, Niger Republic]). Of what significance are gender categories (male and female) in the recruitment of ‘organizers’ and ‘subjects’ of migrants’ smuggling within these study locations? Though it has been assumed that the female gender has often been at the receiving end of most organized irregular mobilities along the Nigerian–Libyan corridor, findings from this study have shown that female network actors have been as active as their male network counterparts in processes of migrants’ smuggling. The outcomes of this study have been particularly useful in situating the interpositions of gender and smuggling of migrants along the Nigerian–Libyan corridor within an appropriate epistemological context.

Résumé :

The Paleogene lacustrine mudstone is one of the most important sets of source rocks in Termit Basin, Niger. However, studies on the Paleogene source kitchen are scarce. In this study, the source rock types, spatial distribution and their hydrocarbon generative potential within the Paleogene Sokor-1 and LV formations are systematically evaluated. A total of two third-order sequences (SSQ1 and SSQ2, from the bottom to top) and six systems tracts were identified in the Sokor-1 Formation, while the LV Formation mainly comprises pure shale and is regarded as a compositive stratigraphic sequence with no need of subdivision. Six types of source rocks could be distinguished within the three depositional environments of the sequence stratigraphic framework: (1) deep lake mudstones and shale deposited in the lacustrine deep-water facies, (2) shallow lake mudstones and carbonaceous mudstones occurring in the shallow lake environment, and (3) deltaic-front mudstones and prodeltaic mudstones developed in the deltaic facies. Deep lake mudstones/shale, which mainly occurred in the SSQ1-TST (transgressive systems tract), SSQ2-TST and LV Formation, are considered organic-rich source rocks with oil-prone generative potential. The shallow lake mudstones and deltaic mudstones were predominantly distributed in the tectonic slope and marginal areas of the Agadem Block within the lowstand systems tract and high stand systems tract of the SSQ1 and SSQ2. Nevertheless, geochemical results indicated that the deltaic mudstones are good gas-prone source rocks but the shallow lake mudstones were classified as poor potential source rocks. The variance in organic matter accumulation and preservation conditions within different depositional facies and the fluctuation of relative lake level are the controlling factors for the occurrence and distribution of high-quality source rocks. The effective Paleogene source kitchen is limitedly distributed around the depocenter of the Dinga Depression within a small scale, and therefore exploration for oil and gas resources from the Paleogene source kitchen should focus on the eastern Dinga fault-step zone adjacent to the depocenter of the Dinga Depression.
