    Coopération Afrique-Europe en matière de recherche et innovation : Défis mondiaux, réponses bi-régionales (2021)
    IRD Éditions
    Details
    Publikationsdatum: 2023-12-20
    Beschreibung: Les relations scientifiques et technologiques entre l'Afrique et l'Europe ont une histoire longue, dynamique et parfois en dents de scie, qui traduit une certaine complexité en termes d'intérêts et de stratégies aux niveaux national, régional et international. Ce livre traite de la coopération dans le domaine de la recherche appliquée, en quête de solutions face aux défis sociétaux communs. Ainsi aborde-t-il quatre défis majeurs. Premièrement, fournir un aperçu compréhensible du paysage mondial des politiques de recherche et d'innovation dans lequel le partenariat stratégique Afrique-Europe fonctionne actuellement. Deuxièmement, procéder à une analyse critique des divers réseaux et organisations qui soutiennent, permettent et renforcent la coopération bi-régionale en matière de sciences, technologies et innovation [STI]. Troisièmement, éclairer les résultats et l'impact de certaines initiatives réelles des entreprises opérant dans le domaine de la STI. Quatrièmement, présenter une série de leçons claires susceptibles d'appuyer les futurs efforts de coopération entre l'Afrique et l'Europe en matière de STI.

    Habitat-mediated timing of migration in polar bears: an individual perspective (2016)
    Wiley
    Details
    Publikationsdatum: 2016-06-28
    Beschreibung: Migration phenology is largely determined by how animals respond to seasonal changes in environmental conditions. Our perception of the relationship between migratory behavior and environmental cues can vary depending on the spatial scale at which these interactions are measured. Understanding the behavioral mechanisms behind population-scale movements requires knowledge of how individuals respond to local cues. We show how time-to-event models can be used to predict what factors are associated with the timing of an individual's migratory behavior using data from GPS collared polar bears ( Ursus maritimus ) that move seasonally between sea ice and terrestrial habitats. We found the concentration of sea ice that bears experience at a local level, along with the duration of exposure to these conditions, was most associated with individual migration timing. Our results corroborate studies that assume thresholds of 〉50% sea ice concentration are necessary for suitable polar bear habitat; however, continued periods (e.g., days to weeks) of exposure to suboptimal ice concentrations during seasonal melting were required before the proportion of bears migrating to land increased substantially. Time-to-event models are advantageous for examining individual movement patterns because they account for the idea that animals make decisions based on an accumulation of knowledge from the landscapes they move through and not simply the environment they are exposed to at the time of a decision. Understanding the migration behavior of polar bears moving between terrestrial and marine habitat, at multiple spatiotemporal scales, will be a major aspect of quantifying observed and potential demographic responses to climate-induced environmental changes. The nature of the relationship between animal behavior and environmental cues varies depending on the scale these interactions are measured. We show how individual-based behavior models can determine local environmental factors associated with polar bear migration from marine to terrestrial habitat during annual sea ice melting events. The amount of ice bears encounter on a daily basis and the length of direct exposure to these conditions are shown to correlate with the decision to migrate.

    Lessons Learned and Cost Analysis of Hosting a Full Stack Open Data Cube (ODC) Application on the Amazon Web Services (AWS) (2018)
    In:  CASI
    Details
    Publikationsdatum: 2019-07-25
    Beschreibung: The Open Data Cube (ODC) initiative, with support from the Committee on Earth Observation Satellites (CEOS) System Engineering Office (SEO) has developed a state-of-the-art suite of software tools and products to facilitate the analysis of Earth Observation data. This paper presents a short summary and cost analysis of our experience using Amazon Web Services (AWS) to host one such software product, the CEOS Data Cube (CDC) web-based User Interface (UI). In order to provide adaptability, flexibility, scalability, and robustness, we leverage widely-adopted and well-supported technologies such as the Django web framework and the AWS Cloud platform. The UI has empowered users by providing features that assist with streamlining data preparation, data processing, data visualization, and the sub-setting of Analysis Ready Data (ARD) products in order to achieve a wide variety of Earth imaging objectives.
