Impulser le développement à partir des solutions sur l'approche endogène

In a context of increasing pressure on water resources due to climate change, rapid urbanisation and population growth, the limits of centralised state approaches to water management are becoming in creasingly apparent. This study is part of a critical analysis of water governance mechanisms at different scales with views on the role of local communities in a multi-scalar system. Its main objective is to examine the extent to which the State's shortcomings in sustainable water management pave the way for local stakeholders greater responsibility. The methodology is based on a systematic and analytical literature review based on Elinor Ostrom's theory of the commons and multi-scalar governance. Scientific sources, institutional reports as well as national and international normative frameworks were consulted. The results reveal a gradual process of powers delegation, often under constra...

Climatic variability at both global and local scales, compounded by the security crisis affecting Burkina Faso since 2015, has driven new dynamics of agro-pastoral conflicts, particularly in the Bougouriba province. This study aims to analyze farmer–herder conflicts in Burkina Faso through the prism of political ecology and the prevailing national security context. It first examines the contentious dynamics surrounding the control of natural resources, notably land, water, and pasture. It then investigates the climatic, environmental, and socio-political drivers of these conflicts, including widespread insecurity, land tenure precarity, and infrastructural crisis. The study draws on political ecology, conflict proximity theory, fieldwork based on structured interviews with both open-ended and closed-ended questions, and thematic documentary analysis. Conflicts over access to land, grazin...

In Burkina Faso, the poultry industry faces significant health challenges, notably coccidiosis, an intestinal parasitic disease that results in substantial economic losses. This cross-sectional clustered study aimed to determine the prevalence and oocyst load of Eimeria (E.) spp. in litter-derived fecal samples from broiler chickens in Batié, Dano, Diébougou, and Gaoua in the Djôrô region of Burkina Faso. The study was conducted from June to September 2024. A total of 600 fresh fecal samples were collected from broiler chickens aged 35 to 45 days, originating from 30 traditional and 30 modern farms across the Djôrô region. The droppings were collected from litter, placed in airtight plastic bags, and stored in cooling boxes at 4°C, then transferred to the Laboratory of Animal Biology and Physiology at the Gaoua University Center, Burkina Faso, for subsequent parasitological analysis. Sam...

Poultry farming plays a vital role in rural livelihoods and is a primary source of animal protein in Burkina Faso. However, the increasing introduction of fast-growing exotic breeds threatens the genetic integrity of local chicken populations. This study aimed to assess the genetic diversity and structure of local chickens using 27 microsatellite markers, of which 23 were selected and 19 polymorphic markers were retained for analysis. A total of 116 individuals from local populations were genotyped, along with 20 individuals of the exotic broiler breed Cobb 500 for comparison. Genetic diversity, Hardy-Weinberg equilibrium, genetic distances, and population structure were evaluated using Bayesian and multivariate approaches. Results showed that 19 loci were polymorphic, revealing high allelic diversity with 117 alleles and a mean of 6.16 alleles per locus. The overall heterozygosity defic...

La valorisation touristique des sites naturels sensibles est aujourd'hui reconnu comme un levier de développement territorial.

This study evaluated fishmeal-free diets based on locally available oilseed meals for Nile tilapia (Oreochromis niloticus) (16 ± 1 g). Six isonitrogenous (35% crude protein), isolipidic, and isoenergetic diets were tested for 42 days in a recirculating aquaculture system. The control diet (D0) contained fishmeal, whereas diets D1 to D5 were formulated with different combinations of soybean meal, cottonseed meal, sesame meal, and Moringa oleifera leaf meal. Fish fed diet D5, containing balanced oilseed meals supplemented with M. oleifera, showed the highest final body weight (30.92 ± 2.04 g), weight gain (14.57 ± 1.31 g), and specific growth rate (1.52 ± 0.06% day⁻¹) (p < 0.05), with a feed conversion ratio (3.35 ± 0.63) comparable to the control diet (p ˃ 0.05). Survival rates remained high (˃86%) and were not significantly affected by dietary treatments (p ˃ 0.05). All fishmeal-free die...

Le cauri est l’une des plus anciennes monnaies connues et usitées en Afrique. Il est la monnaie la plus répandue en Afrique avant la colonisation et, aujourd’hui, celle la plus intégrée dans les pratiques socioculturelles africaines. Ce constat nous amène à nous interroger sur les facteurs de son abandon et de l’attachement des Africains en général, et des Voltaïques à ce coquillage aux origines mythiques dans l’imaginaires des populations. L’objectif du présent article est d’analyser la place des cauris dans le paysage socioculturel voltaïque. Il s’agit essentiellement d’évoquer les facteurs de son rejet par le pouvoir colonial français d’une part, et d’autre part, la forte résilience dont a fait preuve cette monnaie qui, loin de disparaitre s’est taillée une place de choix dans les pratiques sociales et culturelles. Pour atteindre ces objectifs, nous avons accordé une place centrale...

Le couvert végétal de la province du Ioba est sujette à de fortes mutations qui menacent sa durabilité. La présente étude vise à prévoir l’état de cette ressource végétale en 2055. La démarche méthodologie s’articule autour d’une revue de littérature, des collectes des données,de traitement d’images satellites landsat TM de l’année 2000, ETM de 2010 et OLI_TIRS de 2020. Les outils utilisés sont les logiciels de télédétection ENVI, de cartographie ARC Gis, et de projection SpaCelleà travers la méthode des automates cellulaires. La méthode de comparaison visuelle et statistique a été utilisée pour valider la qualité du modèle. Les résultats de cette recherche indiquent qu’entre 2000 et 2020, la superficie des cultures annuelles a connu une hausse de 20,26% suivie des forêt galerie avec 18,95%. Des baisses respectives de 27,82% et de 21,14% sont observées au niveau de la superficie des...

This study aims to evaluate the effect of soaking three types of flour, based on white and yellow hybrid corn 'Zea mays (L.)' and millet 'Pennisetum glaucum (L.)', on physicochemical parameters. The soaking times were 0; 6; 12; 24; 48; 72, and 168 hours for the corn varieties, and 0 and 6 hours for the millet. Two corn flours from grains soaked for 168 hours were produced, one of which was marked by the addition of potash. In total, 18 flours were produced. The analyzed physicochemical parameters showed a significant decrease, particularly after 168 hours of soaking. The minimum and maximum values were observed in the pH of white flour (4.73%) and the ash content of yellow flour (75%), respectively. Similarly, the protein, lipid, and carbohydrate contents decreased significantly. A significant decrease in carbohydrate content of yellow flour (77.28%) is observed. Adding potash further re...
