Hamadou Tahirou Abdoulkarim, Seydou Harouna Fatouma, Hamadou Tahirou Hassane
Journal of Transportation Technologies (JTTs) , 2019, DOI: 10.4236/jtts.2019.92012
Abstract: This work involves the evaluation of dry port competitiveness through analysis of efficiencies for selected dry ports in Africa. Five dry ports were selected and analysis carried out over a period of four years. The dry ports considered were Mojo and Kality in Ethiopia, Mombasa in Kenya, Isaka in Tanzania and Casablanca in Casablanca, Morocco. Data Envelopment Analysis (DEA) was applied for this work. Container throughputs for the various ports under consideration were used as the output variable for the data analysis model, while the number of reach stackers, the number of tractors, the number of forklifts and the size of the dry port were used as the input variables. From the results, the Mombasa dry port was found to be the most efficient with an average score of approximately 1 over the period under consideration. Casablanca was the second efficient dry port with an average score of 0.762, while Isaka was the least efficient with an average score of 0.142. This research is significant since the African countries have embraced the dry port concept, as witnessed in the huge investments in this sector, and would serve to highlight areas that need improvement for the few existing dry port facilities, most of which are undergoing expansion as well as modernization.

Open Journal of Social Sciences (JSS) , 2019, DOI: 10.4236/jss.2019.75001
Abstract: The paper studied 5 transport corridors in West Africa, from the ports of Abidjan, Cotonou, Lagos, Lomé, and Tema, to the landlocked countries (LLCs) of Burkina Faso, Mali, and Niger. The study found 15 transport routes available from these ports to the LLCs. It used two modes of transport with their respective transport costs as variables influencing shippers in their choice of corridor route. In regards to the modes of transport, the study chose the unimodal road transport and the intermodal transport as the combination of the rail and road transport, with a projection of the cargo volume demand in 2023 from the LLCs. In addition, a survey conducted on the Togolese corridor with the aim to find from users’ perspective the adequate intermodal terminal location, identified the city of Mango as an ideal host. As for the transport cost analysis attached to each of the modes of transport, the results of this study revealed that in the case of the unimodal road transport, shippers from Burkina Faso would rather choose Tema port in Ghana as optimal route, while shippers from Mali would rather choose Abidjan port in Ivory Coast, and shippers from Niger would choose Cotonou in Benin as the optimal route. Consequently, the study also found that the added parameter of the intermodal terminal of Mango on the Togolese corridor would change the routing habit of the LLCs shippers. In fact, with this parameter in line, the Togolese corridor would be optimal in terms of transport cost minimization for the Niger and Burkina Faso shippers. Based on these findings the study highlights the benefits of the intermodality which it presents to the policymakers.

Seydou Harouna Fatouma, Shen Lei, Hamadou Tahirou Abdoulkarim
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.47020
Abstract: In recent years worldwide boundaries have been redefined, thanks to internet and technologies which facilitate increasingly the interaction between virtual friends and socials networking users. Consumers as well as producers in both developed and developing countries share information, pictures and videos via the Web 2.0 tools available on electronic devices and Internet websites. However due to several obstacles, activities such as co-creations, digital collaboration and others socials networking can be limited for some users. Thus this article discussed various factors that limit developing countries’ prosumers interactivity in the age of Web 2.0 technology. The factors influencing numbers of users’ collaboration can be individual, organizational, technological and/ or environmental factors.
Dry Ports in China and West Africa: A Comparative Study  [PDF]

American Journal of Industrial and Business Management (AJIBM) , 2019, DOI: 10.4236/ajibm.2019.93030
Abstract:
The dry port concept was first adopted in Europe and North America, followed by Asia, South America and then Africa. Since then, the development of inland cargo distribution facilities has been an active approach to support the hinterlands of maritime gateways among other functions. Dry ports can be developed in the hinterland based on different approaches, involving differing functions, actors, motivations and logistical models. They can be classified as close, mid-range or distant, with respect to the seaport. Dry port development can be carried out by port authorities, port terminal operators and transport providers such as third-party logistics providers or rail operators or by public bodies: local, national or regional. One of the design strategies for these facilities is rail-based which promotes economies of scale on high capacities and long distance links. The other strategy is the road-based short-distance satellite terminals aimed at decongesting the port or facilitating faster custom clearances. This paper carries out a comparative analysis of dry ports in China and the West African countries using a descriptive approach and providing case studies for each parameter used in the comparative study. This study is based on motivations for dry port development in these regions, as well as the development and management models applied in the dry port sector. In addition, a discussion on the merits and demerits of the management and development models applied on dry ports in these regions are also included in this study, from which conclusions and recommendations are drawn to support policy formulation and future studies. This paper not only serves to contribute to the existing academic knowledge on dry ports, but also provides the policy makers and practitioners in the logistics and trade sectors with an invaluable opportunity to compare the practices in the two regions for application to appropriate scenarios.
The Selection of Dry Port Location by Analytic Network Process Model: A Case Study of Dosso-Niger  [PDF]
Hamadou Tahirou Abdoulkarim, Seydou Harouna Fatouma, Bomboma Kalgora
Journal of Transportation Technologies (JTTs) , 2019, DOI: 10.4236/jtts.2019.92009
Abstract: The aim of this paper is to select the best location for the construction of a dry port in Niger which is a land locked country (LLC). Niger is located in the Sahel and has a land area of 1,267,000 square kilometers [1], with the closest port being port of Cotonou in Benin. The transport corridor from Niamey to Cotonou is approximately 1036 km long [2]. It is estimated that this corridor carries about 40 percent of Niger’s overseas trade traffic [3]. In this work, the Analytic Network Process (ANP) model is used to determine the optimal location of the dry port, among three major cities: Niamey (capital city), Dosso and Gaya. From the application of this selection model, Dosso was selected as the best location for the location of the dry port, while Gaya and Niamey were placed second and third respectively. The results obtained in this work strongly confirm the decision of the government of Niger to construct a dry port in Dosso, a project that commenced in 2010 and is still in progress.

Journal of Transportation Technologies (JTTs) , 2019, DOI: 10.4236/jtts.2019.93018
Abstract: The present study measured the relative efficiency of five major commercial ports in West Africa, using three different Data Envelopment Analysis (DEA) methods, the CCR, BCC, and Windows I-C methods over the years 2005-2016. Seven input variables and one output variable were used in the model analysis. The CCR and BCC methods were used to evaluate the technical and scale efficiency while the Windows I-C method provided a comprehensive ranking of the studied ports. The results showed that the scale efficiency score of 89.53% indicated that on average the production scale of the ports had deviated from the most productive scale size (MPSS) by 10.47%. These results revealed that the source of the overall inefficiency is due to scale rather than pure technical inefficiency. Hence, in order to improve the overall efficiency, the two scaled inefficient ports of Abidjan and Cotonou should adjust their scale of operations. Then, further investigations were conducted to detect correlations between various variables used in this study. The research found that the absence of any correlation for non-significant variables and negative correlation for the significant variables throughout time resulted from the fact that these variables were not fully utilized. Meaning that they were not efficiently used to boost the container throughput on a scale basis, the research also found that a pandemic or insecurity could easily impact seaports activities with the case of the Ebola outbreak which strucked the West African region from the year 2013 to 2016, or the terrorism threats which prevailed in the region around the year 2012. Thus, for ports to stand out in the present fiercely competitive environment, ports authorities ought to analyze their operational scale to identify whether or not the production size is fitting before further port capacity expansion.
Restricted Application of Insecticides: A Promising Tsetse Control Technique, but What Do the Farmers Think of It?

PLOS Neglected Tropical Diseases , 2011, DOI: 10.1371/journal.pntd.0001276
Abstract: Background Restricted application of insecticides to cattle is a cheap and safe farmer-based method to control tsetse. In Western Africa, it is applied using a footbath, mainly to control nagana and the tick Amblyomma variegatum. In Eastern and Southern Africa, it might help controlling the human disease, i.e., Rhodesian sleeping sickness as well. The efficiency of this new control method against ticks, tsetse and trypanosomoses has been demonstrated earlier. The invention, co-built by researchers and farmers ten years ago, became an innovation in Burkina Faso through its diffusion by two development projects. Methodology/Principal Findings In this research, we studied the process and level of adoption in 72 farmers inhabiting the peri-urban areas of Ouagadougou and Bobo-Dioulasso. Variables describing the livestock farming system, the implementation and perception of the method and the knowledge of the epidemiological system were used to discriminate three clusters of cattle farmers that were then compared using indicators of adoption. The first cluster corresponded to modern farmers who adopted the technique very well. The more traditional farmers were discriminated into two clusters, one of which showed a good adoption rate, whereas the second failed to adopt the method. The economic benefit and the farmers' knowledge of the epidemiological system appeared to have a low impact on the early adoption process whereas some modern practices, as well as social factors appeared critical. The quality of technical support provided to the farmers had also a great influence. Cattle farmers' innovation-risk appraisal was analyzed using Rogers' adoption criteria which highlighted individual variations in risk perceptions and benefits, as well as the prominent role of the socio-technical network of cattle farmers. Conclusions/Significance Results are discussed to highlight the factors that should be taken into consideration, to move discoveries from bench to field for an improved control of trypanosomoses vectors.
The Impact of FDIs Flows on the Nigerien Economic Growth

International Journal of Financial Research , 2011, DOI: 10.5430/ijfr.v2n2p16
Abstract: Niger, since the 70s has always adopted an approach that makes the IDE a major component of its development plan. It `s so, a series of measures have been taken to make the country more attractive to Foreign direct investment FDI This policy has guaranteed the country a few annual flow between the period 1970 to 2008.The aim of this paper is to try to study the impact of FDI on economic growth in Niger. Observe the literature study on FDI in Niger, however, it is also becoming important to see the between FDI and economic performance since it has not been addressed specifically yet. While it is still unclear of whether there is any relationship between FDI and economic growth in Niger, especially as regard to the causality within the relationship. The theory and the current empirical literature on the relationship between FDI and growth have provided ambiguous results. Using VAR (Vector Autoregressive) model, this paper explores the causal relationship between FDI and economic growth for the period 1970-2008 in Niger. With in the Granger causality framework, this study finds a long-term relationship between FDI and economic growth. This finding is a long-term relationship between variables but failed to establish the direct correlation between each variable. This can be explained by the fact that low volume flows of FDI in Niger have major consequences on the economic system, particularly on employment, inflation and GDP. More, this weakness is emphasized by the insignificance of the volume of capital flows (domestic and foreign) circulating in the Nigerian economy and domestic savings.
Choix linguistique et modernité islamique au Cameroun Linguistic choices and Islamic modernity in Cameroon: the case of Fulfulde and Arabic.

Revue des Mondes Musulmans et de la Méditerranée , 2011, DOI: 10.4000/remmm.6012
Abstract: This paper discusses the interplay between Islam, Arabic and Fulfulde in Cameroon with regard to a dual relationship based on competition and cooperation. Language plays a predominant role in the relationship between the universality of the Islamic dogma and the contextualized interpretations of it. The exploration of the cross-currents of fulanization [Fulfuldization] of Arabic and Arabization of Fulfulde, the interference between the linguistic activism of Christian missions and Muslim militants and the relation between orality and writing shed light on the internal and external dynamics and on the modes of invention/reinvention of a certain modernity. The proponents of the Islamic tradition and the militants of modernity maintain a realistic relationship, translated at the linguistic level into mixing and mutual influences between Arabic and Fulfulde. Cet article aborde les questions de l’interface entre islam, langue arabe et fulfulde au regard d’une double relation de compétition et de coopération dans l’espace camerounais. à travers le rapport entre l’universalité du dogme islamique et les interprétations contextualisées de ce dogme, la langue joue un r le de premier plan. L’exploration des processus croisés de fulanisation de l’arabe et d’arabisation du fulfulde ainsi que les interférences entre l’activisme linguistique des missions chrétiennes et des militants musulmans et le rapport oralité/écriture éclairent sur les dynamiques tant internes qu’externes et sur les modalités d’invention ou/et de réinvention d’une certaine modernité. Au-delà des interférences entre langues, savoirs et pouvoirs et des situations de compétition au sein de la société musulmane et face aux églises et à l’état colonial puis postcolonial, au-delà des contingences, de l’instrumentalisation, du communautarisme et des enjeux qu’on imagine plus ou moins importants, les tenants de la tradition islamique et les partisans de la modernité entretiennent pour l’heure une relation somme toute réaliste dont l’issue, au plan linguistique, se déclinerait en termes de métissage et d’influences réciproques fécondes entre l’arabe et le fulfulde.

Hassane Jarar Oulidi, Aniss Moumen
Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.76054
Abstract: International studies of expertise have shown that the difficulty of data access is one of the major hindrances that brakes any effort to conduct studies on groundwater. This research paper is an attempt to address this problematic through developing a technical framework to implement a Spatial Data Infrastructure (SDI) with a view to improving the status of access to data related to groundwater in Morocco, and achieving their interoperability. This prototype is primarily based on international standards (OGC & ISO) such as Web Map Service (WMS), Web Feature Service (WFS), Catalog Web Service (CSW) and Sensor Observation Service (SOS) accompanied by the use of associated specifications such as Geography Markup Language (GML) and Filter Encoding (FE). This platform is considered both as a tool for sharing updated data collected from numerous and divers source providers, and as a tool of web-based GIS for groundwater management, which constitutes the basis for decision making.
