[hal-01722629] Balanites aegyptiaca (L.) Delile: geographical distribution and ethnobotanical knowledge by local populations in the Ferlo (north Senegal)
Oct 25, 2020 | 07:30 amBalanites aegyptiaca (L.) Delile is a species of tropical flora for which the variety aegyptiaca is adapted to Sahelian climate. The species is among those chosen for the restoration of Sahelian ecosystems in the context of the pan-African reforestation project, the Great Green Wall for the Sahara and Sahel Initiative (GGW). This study redefines the distribution range and its ecology and studies its uses in the Ferlo region in the north of Senegal using surveys carried out among the local population. The eco-geographical study shows that the species occupies several Sahel-Saharan regions of Africa and the Middle East. With broad ecological amplitude, it is very resistant to drought and relatively indifferent to the type of soil. Results of the ethno-botanical survey show that local people in the Ferlo region have a wealth of knowledge and expertise on B. aegyptiaca. These surveys also revealed the extent to which local populations rely[…]

[halshs-01521743] Perception de l'arbre en contexte Sahélien
Oct 23, 2020 | 18:39 pmDans 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-01723198] Effets des principales essences de la grande muraille verte sénégalaise sur les taux d'azote minéral du sol et la biomasse microbienne
Oct 20, 2020 | 16:05 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-02382056] Promote Open Science within the DRIIHM Interdisciplinary Research Facility on Human- Environment Interactions: Co-design of an e-infrastructure implementing the FAIR Principles
Oct 14, 2020 | 05:50 amAs part of the international Open Science movement, this project deals with the structuration, sharing and opening of research data in the context of a network of thirteen CNRS-INEE observatories (OHMs): the Interdisciplinary Research Facility on Human-Environment Interactions supported by the ANR (LabEx DRIIHM 2012-2025). This network involves nearly 1000 scientists. Large amounts of heterogeneous data are produced or collected, covering research in Natural and Life Sciences, and Human and Social Sciences. Several initiatives have been carried out within the LabEx DRIIHM to increase visibility and data sharing to connect scientific teams that are not always linked, promote the re-use of data and potentially lead to the emergence of new research topics. A range of tools has been developed over the years: metadata geo-catalogs, web GIS platforms, photo libraries, HAL collections, etc. However, there are significant contrasts in the contribution to these tools and their use between OHMs, and two[…]

[hal-01350584] Variabilité de la capacité de sorption du glyphosate et diuron des fonds de fossés évaluée à l'aide de nouveaux indicateurs
Oct 14, 2020 | 05:49 amLes réseaux de fossés jouent un rôle clé dans la gestion des flux hydriques et sédimentaires au sein des bassins versants agricoles ce qui leur confère une importance particulière dans le devenir des pesticides (Dollinger et al., 2015). En effet, bien que constituant des voies de dispersion, par la collecte et l’acheminement des flux de ruissellement ou de drainage potentiellement chargés en pesticides, les fossés ont été décrits comme des zones tampons efficaces pouvant limiter la pollution des masses d’eau (Dollinger et al., 2015; Needelman et al., 2007). Le pouvoir tampon des fossés vis-à-vis des pollutions par les pesticides résulte essentiellement de processus de sorption sur les différents matériaux des fonds de fossés (e.g., Stehle et al., 2011). La capacité de sorption de pesticides est d onc étroitement liée à l a nature et à l’abondance des différents matériaux constituant les fonds de f ossés tels que le sol, la[…]

[hal-02373055] SO-DRIIHM - Impulser la science ouverte au sein du LabEx DRIIHM : Co-design d'une e-infrastructure intégrant les principes FAIR
Oct 12, 2020 | 12:54 pmDans le cadre du mouvement international de la science ouverte, ce projet traite de la structuration, du partage et de l’ouverture des données produites au sein d’un réseau de treize observatoires (OHMs) du CNRS-INEE : le Dispositif de Recherche Interdisciplinaire sur les Interactions Hommes-Milieux soutenu par l’ANR (LabEx DRIIHM 2012-2025). Il implique près de 1000 scientifiques. De grandes quantités de données hétérogènes sont produites ou collectées dans les domaines des Sciences de la Nature et du Vivant, et des Sciences Humaines et Sociales. Plusieurs initiatives ont été menées au sein du LabEx pour augmenter la visibilité et le partage des données, mettre en relation des équipes scientifiques, favoriser la ré-utilisation de données et potentiellement faire émerger de nouvelles recherches. Un panel d’outils a ainsi été mis en place au fil des années : géo-catalogues de métadonnées, web SIG, photothèque, collections HAL, etc. Cependant, il existe des contrastes importants dans l’alimentation[…]

[hal-02322991] SO-DRIIHM: promoting Open Science within the LabEx DRIIHM and improving its Research Data Infrastructure
Oct 12, 2020 | 12:54 pmThe "SO-DRIIHM" project has just obtained funding from the Flash Call "Open Science: research practices and open research data" proposed by the ANR in 2019. It is managed by a group of geomatics and IT engineers within the CNRS interdisciplinary network (LabEx DRIIHM) of 13 Human-environment observatories (OHMs). The objective of this project (May 2020 - April 2022) is to optimize the appropriation of the open science approach by the DRIIHM research community through: •the organisation of awareness campaigns showing the benefits of data sharing and openness; •the co-construction of a more ergonomic and interoperable e-infrastructure, integrating existing tools (metadata geocatalogues, web GIS, photo library, HAL collection, etc.) and accompanying researchers to find, share and (re)use data with the concrete and progressive implementation of the FAIR principles (Findable, Accessible, Interoperable, Reusable). The originality of this project lies in the bottom-up co-construction of the e-infrastructure, involving researchers from the early stages[…]

[hal-01617308] Questioning capitalistic power structures: a way to reconnect stakeholders with the land?
Jul 20, 2020 | 15:06 pmFrom 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[…]
