[hal-03716554] Taxonomic and functional diversity of insect visitors to the flowers of five tree species in the Sahelian savannah of Ferlo, Senegal
Degradation and restoration are two central processes within the Great Green Wall initiative in Senegal. Degradation caused by human activities, in interaction with global changes, leads to the loss of habitats and the disappearance of many species. It is therefore necessary to know the state of diversity in order to be able to protect it and better understand how to restore it, notably by re-establishing interspecific interactions within the ecosystems concerned by the restoration. In our study we are interested in the interactions between plants and flower visitors, and more specifically pollinators. A first sampling was conducted in three different localities in the Ferlo in northern Senegal, in order to be able to differentiate the dominant guilds of insects that interact with the flowers of certain trees present in this Sahelian zone. We carried out a rapid sampling of insects interacting with the flowers of four tree and shrub species[…]

[hal-03716553] Value chain analysis of Balanites aegyptiaca (L.) DEL. and Ziziphus mauritiana Lam. fruits in the Ferlo (Senegal).
Despite the important socio-economic role of non-timber forest products from the Great Green Wall in Senegal, little is known about their contribution to the local or national economy. This study aims to analyse the value chain of Balanites aegyptiaca and Ziziphus mauritiana fruits in the Sahelian zone of Senegal. To this end, a socio-economic survey was conducted in the Ferlo area (Widou Thiengoly, Amaly, Labgar, Téssékéré and Dahra) and in the major cities where products from the Great Green Wall are sold, namely Dakar, Thiès and Touba. Individual structured interviews were conducted with a questionnaire administered to 260 people in the study sites. The surveys revealed that only fruits of Balanites aegyptiaca (51%) and Ziziphus mauritiana (49%) species are harvested. Harvesting is almost exclusively done by women (98%). The highest usage values obtained from harvesters (3.05) and consumers (1.73) concern B. aegyptiaca. In the Ferlo, the traders surveyed (banabanas) buy[…]

[hal-03716542] Environmental memories in the Ferlo
The Sahelian territory of Ferlo in Senegal, mainly inhabited since the 19th century by Fulani pastoralists, is particularly exposed to current environmental changes. In a territory that is already arid, drought and landscape transformations modify the adaptation strategies of the inhabitants. Thus, the Ferlo is a particularly interesting area for studying environmental memories, defined as representations of the environment and its interactions with human communities or individuals, during a past experience more or less close, lived or transmitted. The study of these memories follows, in particular, the observation of a forgetting of past environmental conditions by younger generations due to a lack of intergenerational transmission (generational environmental amnesia). This forgetfulness can lead to a greater acceptance of the degradation of natural spaces and environmental conditions (desertification, pollution...) because the previous conditions are no longer known. This project explores the different cultural, psychological and environmental factors that can promote environmental memories,[…]

[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
As 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-02373055] SO-DRIIHM - Impulser la science ouverte au sein du LabEx DRIIHM : Co-design d'une e-infrastructure intégrant les principes FAIR
Dans 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
The "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[…]

[halshs-01521743] Perception de l'arbre en contexte Sahélien
Dans 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[…]
