[hal-01350584] Variabilité de la capacité de sorption du glyphosate et diuron des fonds de fossés évaluée à l'aide de nouveaux indicateurs
Sep 25, 2020 | 18:02 pmLes 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-02382056] Promote Open Science within the DRIIHM Interdisciplinary Research Facility on Human- Environment Interactions: Co-design of an e-infrastructure implementing the FAIR Principles
Sep 22, 2020 | 17:01 pmAs 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-02322991] SO-DRIIHM: promoting Open Science within the LabEx DRIIHM and improving its Research Data Infrastructure
Sep 18, 2020 | 16:34 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-02373055] SO-DRIIHM - Impulser la science ouverte au sein du LabEx DRIIHM : Co-design d'une e-infrastructure intégrant les principes FAIR
Sep 18, 2020 | 16:34 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-01723198] Effets des principales essences de la grande muraille verte sénégalaise sur les taux d'azote minéral du sol et la biomasse microbienne
Sep 17, 2020 | 12:12 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-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[…]

[hal-01722639] Comparing genetic diversity of Sitophilus zeamais (Motchulsky) populations sampled in several agro-ecological areas between Central African Republic and Senegal
Jul 2, 2020 | 16:18 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[…]
