[halshs-01521743] Perception de l'arbre en contexte Sahélien
Jan 8, 2020 | 10:56 amDans le cadre de l’OHMi – Téssékéré et de l’ANR « Future Sahel », une recherche est conduite sur les usages des arbres en tant que pourvoyeur de ressources et vecteurs de services écosystémiques pour les acteurs locaux. En fonction du degré d’enclavement des zones concernées par l’étude, mais aussi des espèces botaniques accessibles et des pratiques culturelles et culturales locales qui leur sont associées, l’arbre sera utilisé (ou non) dans son intégralité (et peut-être différemment) par les hommes ou leurs troupeaux. Cette dépendance critique met l’ensemble des services écosystémiques liés aux arbres en tension et mieux comprendre la place qu’occupe l’arbre dans l’espace perçu et l’espace vécu des populations sahéliennes devient un facteur clef la gestion des ressources naturelles et plus particulièrement pour les stratégies de reboisement lancé dans le cadre de la grande muraille verte au Sénégal. Cette meilleure compréhension constitue également un des éléments clés de l’accroissement de résilience[…]

[hal-01617308] Questioning capitalistic power structures: a way to reconnect stakeholders with the land?
Jan 8, 2020 | 10:56 amFrom our different research fields, by comparing the relationships between local populations and their territory, we noted some similarities. This paper aims to analyze the relationship between local or indigenous stakeholders and their territory. We thus wondered on the possibilities to create a common framework to represent social dynamics of human groups regarding their management of natural resources. We focus on the evolution of collective behaviors in space and time and process of domination which tend to create a gap between human and their land. Capitalistic colonialism has considerably changed the territorial visions and practices of the people. Philosophical conception of the natural philosophy has shifted from the dependence on the land and resources to a domination of Nature (Gregory, 2001; Kaika 2005; Linton 2010). New centralized power structures appeared legitimizing and promoting the implementation of capitalistic lecture of the territory. In the South of France, the farmers have modified[…]

[hal-01722639] Comparing genetic diversity of Sitophilus zeamais (Motchulsky) populations sampled in several agro-ecological areas between Central African Republic and Senegal
Dec 23, 2019 | 12:04 pmMaize is attacked by many post-harvest pests including Sitophilus spp and Prostephanus spp, which causes remarkable loss during storage. Approximately 30 to 40 % loss in the absence of treatment has been reported worldwide. This study compare genetically Central African and Senegalese populations of Sitophilus zeamais from various agroecological zones using 3 markers namely cytochrome b, cytochrome oxidase and nuclear 28S gene. S. zeamais samples were analyzed on both of two other sites 34 for the 28S gene; 68 for cytochrome b and 36 for the cytochrome oxydase. Results analyzed by AMOVA have shown high genetic variation outside population of each country (6.17 % with Cyt b; 21.45 % with 49.83 % and COI in the case of 28S) and low within subpopulations (-10.06 % for Cyt b, 9.36 % for the COI and-15.23 % for 28S). Majority haplotype is shared between the two populations for 28S and cytochrome b[…]

[hal-01723198] Effets des principales essences de la grande muraille verte sénégalaise sur les taux d'azote minéral du sol et la biomasse microbienne
Dec 18, 2019 | 15:54 pmAn experiment was conducted over nine months in a field system in northern Senegal in order to determine the effects on soil nitrogen (N) cycling and the microbial biomass-C properties of five plant species proposed for the Senegalese Great Green Wall (GGW): Acacia senegal (L.) Willd., Acacia tortilis var. raddiana (Savi) Brenan, Balanites aegyptiaca (L.) Del., Boscia senegalensis (Pers.) Lam. ex Poir., and Sclerocarya birrea (A. Rich.) Hochst. Soil samples were collected to a depth of 0-10 cm, outside (control) and beneath tree canopies. Microbial biomass, inorganic N content and net mineralization of organic N were determined for the soil samples collected under trees, and compared to soils collected outside tree canopies. The results showed that concentrations of inorganic N and soil microbial biomass-C were generally higher under canopy cover and differed according to species. In May 2014 (end of the dry season), microbial biomass-C was higher under A. senegal[…]

[hal-01761452] Self-rated health in Senegal: A comparison between urban and rural areas
Oct 23, 2019 | 19:16 pmIntroduction : Although the relationship between mortality and self-rated health has been demonstrated in sub-Saharan Africa, information in this area is rudimentary. In Senegal, no study has been undertaken comparing self-rated health between urban and rural areas. The objective of this study is therefore to compare self-rated health and its main predictors in Dakar and in a rural isolated area, Tessekere municipality, taking into account socio-demographic and economic factors, social relations, as well as measures of physical and mental health. Material and methods : This study was carried out in 2015 on a population sample of 1000 individuals living in Dakar and 500 individuals living in the municipality of Tessekere, constructed using the quota method. Self-rated health, health variables, psychosocial, sociodemographic and economic characteristics were collected during face-to-face interviews. Statistical analyses used were Chi-square tests and binary logistic regressions. Results : Results show that self-rated health in Senegalese urban area[…]
