La présente étude explore la diversité des systèmes d'élevage des dromadaires dans la zone périurbaine de Tahoua, au Niger, afin de mieux comprendre leurs dynamiques et leurs implications socio-économiques. La méthode d'échantillonnage ''boule de neige'' a permis d'atteindre les éleveurs qui ont fait l'objet de l'étude. À partir de données collecté...

This work was a literature review of the available data on the plant diversity in protected areas in Niger. It was based on several studies carried out in the period from 2005 to 2021 in nine (9) reserves of Niger. It aimed to assess the current state of the floristic diversity and ecosystem services in these protected areas. The results revealed t...

La présente étude a pour objectif d'évaluer l'impact potentiel des changements climatiques sur les habitats de la prune noire (Vitex doniana Sweet.) au Sud-Ouest du Niger. Cette espèce ligneuse multi-usages est soumise à des fortes pressions anthropiques. Le principe d'entropie maximale (MaxEnt) en combinaison avec le Système d'Information Géograph...

Weed competition is a major obstacle to millet cultivation [Pennisetum glaucum (L.) R. Br. (Poaceae)]. The present study was conducted in the south-east of Niger to determine the density of Leucas aspera (Willd.) Link (Lamiaceae) likely to influence millet production, in order to help farmers define technical itineraries for controlling this specie...

Weed control is one of the most important constraints to crop production. This study was undertaken in the south-east of Niger. The aim of the study was to assess the impact of weed control on millet production in this area. Experiments focused on the growth (height and tillering) and grain weight of millet plants subjected to competition from Cass...

The cultivation of date palm, a pillar of oasis agrosystem constitutes a real source of development in arid and semi-arid zones because of its fruit’s rich in sugars and various products, essential to daily life of the populations. In Chad, date production has experienced a decline since the sixties, in relation to diseases, pests and poorly perfor...

Weed infestation is, after the negative effects of climate variability and change, the second most important factor in grain reduction. The present study, carried out in the southeast of Niger, aims to determine the weeding period that can influence millet production. The experimental setup used is a complete Fisher block, comprising 36 elementary...

In Niger, the cumulative effects of successive years of drought and anthropic pressures have resulted in significant declines in the quality and quantity of natural resources. The present study aims to characterize the woody vegetation of the 527261.75ha Dosso Partial Wildlife Reserve. To this end, the analysis highlighted a characterization along...

Striga represents a significant constraint to food production. Despite its harmful effects, striga is regularly sought in the markets for uses miscellaneous. The general objective of this work is to collect all the information on the use made of this harmful species. Field surveys were carried out in the 6 regions of Niger (Dosso, Maradi, Niamey, T...

Sickle cell anaemia is a hereditary blood disorder that attacks the red blood cells and deforms them, giving them a sickle shape. Sickle cell anaemia is a serious health problem in the West African country of Niger. Moreover, the cost associated with medical care is very high. The main objective of this study is to contribute to the valorisation of...

Background and Objective: The genetic structuring of populations could be explained by several parameters such as geographical distance and anthropogenic activities. The Niger date palm population is genetically structured into biogeographical distribution of subpopulations; however, it is important to find out the main causes of this structuring....

Balanites aegyptiaca contributes strongly to the resilience of Sahelian populations. All the organs of B. aegyptiaca are used either for food, medicinal purposes or for other services. However, very few studies on the socioeconomic importance of B. aegyptiaca have been conducted in Niger. The main objective of this study was to valorize the knowled...

La spiruline est un complément alimentaire peu consommé au Niger. L'objectif de cette étude est d'évaluer la consommation et l'acceptabilité de la spiruline dans la ville de Niamey. Pour atteindre cet objectif, une étude descriptive transversale à viser analytiquea été réalisée dans les cinq (5) l'arrondissements communaux de la ville de Niamey. Au...

In Niger, several types of tools and products are used for the storage of Bambara groundnut. The objective of this study was to identify the tools and products used to prevent the damage of Callosobruchus maculatus (Fab.) On Bambara groundnut seeds in storage. Structured sowing questionnaires were administered to 404 heads of households in 16 targe...

The groundnut is a leguminous, olea-proteaginous, cultivated in all the tropical zones throughout the world. In Niger, groundnut is used both as a cash and food crop and is highly valued for its nutritional and economic qualities. In order to show the local diversity of groundnut and its place in the cultivation system in Niger, a prospecting surve...

Resistance phenomena of infectious agents to synthesis drugs and the high cost of these drugs led to medicinal plants as an alternative against infectious disease. The objective of this study is to characterize different classes of secondary metabolites and to test the antibacterial activity of six plants: Bauhinia rufescens Lam, Blepharis linariif...

The present study was initiated to determine the morphobiometric characteristics of local chicken population in Niger. A total of 554 chickens (156 males and 398 females) were sampled in the four (4) agro-ecological zones of the country. A complete description by direct observation, individual weighing and body measurements were performed on the en...

Phoeniciculture, or date palm cultivation plays a major socio-economic and ecological role. However, few studies have quantified the drivers of date palm cultivation and its socio-economic and environmental benefits in West African Sahel. Therefore, this study assessed the effect of anthropic and environmental factors on quantitative and qualitativ...

Several multivariate statistical methods are used in population genetics but there are very few studies that have revealed the strengths and weaknesses of different methods. Thus, this study aims to reveal the strengths and weaknesses of the different multivariate statistical methods used in population genetics through the world. This synthesis is...
