L'IRD (Institut de Recherche pour le Développement) est un établissement public français à caractère scientifique et technologique, qui intervient depuis plus de 60 ans dans les pays du Sud. Il est placé sous la double tutelle des ministères chargés de la Recherche et de la Coopération. Ses activités de recherche, d'expertise, de valorisation et de formation ont pour objectif de contribuer au développement économique, social et culturel des pays du Sud. Elles se déclinent autour de six priorités : la lutte contre la pauvreté, les migrations, les maladies émergentes, les changements climatiques et aléas naturels, l’accès à l'eau et les écosystèmes.

Depuis septembre 2008, le siège de l'IRD est localisé à Marseille. L'institut dispose de 57 unités de recherche : 30 implantations dont 2 en France métropolitaine (Bondy, Montpellier), 5 dans les régions et collectivités d'outre-mer (la Réunion, Guyane, Martinique, Nouvelle-Calédonie, Polynésie française) et 23 dans des pays situés dans la zone intertropicale, en Afrique, en Méditerranée, en Asie et en Amérique Latine.

Les résultats des recherches menées à l’IRD sont publiés sous forme d’articles dans des revues scientifiques, mais également sous forme d’ouvrages, de cartes, de communications dans des colloques, etc. L’Institut dispose de deux bases très riches et très utiles :  "Sphaera " spécialisée sur la cartographie et "Horizon/Pleins textes" centrée sur les publications. Celle-ci permet d'une part d'accéder au catalogue complet de tous les centres de documentation, et d’autre part à un fonds de 67000 publications scientifiques produites par l’IRD, dont 37000 en accès libre et en texte intégral.

Les recherches proposées dans les deux cas sont simples et avancées (avec cependant parfois un accès réservé en intranet). De même une entrée par chronologie ou par thématiques (océanographie / hydrobiologie, sciences du monde végétal et animal, sciences de la Terre, santé, sciences humaines et sociales, sciences fondamentales et techniques) est appréciable. Un seul petit bémol : il n’est pas possible de sélectionner uniquement les documents numérisés dans le formulaire de recherche. Dans la liste des résultats, ils sont alors repérables par l’icône PDF. Enfin, un fil RSS permet d’être averti de toutes les dernières publications référencées dans la base.

Le site est en langue française.

  • > A distinct and reproducible teleconnection pattern over North America during extreme El Niño events

    El Nino-Southern Oscillation (ENSO) teleconnections are an important predictability source for extratropical seasonal climate forecasts. Previous studies suggest that the ENSO teleconnection pattern depends on the ENSO phase (El Nino vs. La Nina) and/or Sea Surface Temperature (SST) pattern (central Pacific vs. eastern Pacific El Nino events). Observations and ensemble simulations with the CNRM-CM6.1 atmospheric general circulation model indicate that only extreme El Nino events (e.g. 1982-19...

  • > Co-designing a method to assess agroecological transitions : results of a case study in Senegal

    Assessing the conditions and performance of agroecological transitions in different contexts is key to supporting these transitions. However, assessing agroecological transitions presents methodological challenges, including: 1) being adaptable to local conditions, 2) consideration of social interactions among stakeholders involved in transitions, 3) clarifying the concept of agroecology, 4) consideration of the temporal dynamics of the transitions to better understand barriers and levers in ...

  • > Comparative phylogenomics and phylotranscriptomics provide insights into the genetic complexity of nitrogen-fixing root-nodule symbiosis

    Plant root-nodule symbiosis (RNS) with mutualistic nitrogen-fixing bacteria is restricted to a single clade of angiosperms, the Nitrogen-Fixing Nodulation Clade (NFNC), and is best understood in the legume family. Nodulating species share many commonalities, explained either by divergence from a common ancestor over 100 million years ago or by convergence following independent origins over that same time period. Regardless, comparative analyses of diverse nodulation syndromes can provide insi...

  • > Cell cycle status of male and female gametes during Arabidopsis reproduction

    Fertilization in Arabidopsis (Arabidopsis thaliana) is a highly coordinated process that begins with a pollen tube delivering the 2 sperm cells into the embryo sac. Each sperm cell can then fertilize either the egg or the central cell to initiate embryo or endosperm development, respectively. The success of this double fertilization process requires a tight cell cycle synchrony between the male and female gametes to allow karyogamy (nuclei fusion). However, the cell cycle status of the male a...

  • > Clade I-associated mpox cases associated with sexual contact, the Democratic Republic of the Congo

    We report a cluster of clade I monkeypox virus infections linked to sexual contact in the Democratic Republic of the Congo. Case investigations resulted in 5 reverse transcription PCR-confirmed infections; genome sequencing suggest they belonged to the same transmission chain. This finding demonstrates that mpox transmission through sexual contact extends beyond clade IIb.

  • > Biogeochemical evidence of flow re-entrainment on the main fringing reef of La Reunion Island

    Understanding factors influencing seawater chemistry variability in coral reef environments is a major challenge to improve predictions of their evolution in the context of ocean acidification. In this study, autonomous sensors for current speed and direction, photosynthetically active radiation (PAR), temperature, salinity, dissolved oxygen (DO) and pHT were deployed three times between 2021 and 2022 offshore and on three reef flat sites of the main fringing reef of La Reunion Island. Discre...

  • > Advances and knowledge gaps on climate change impacts on honey bees and beekeeping : a systematic review

    The Western honey bee Apis mellifera is a managed species that provides diverse hive products and contributing to wild plant pollination, as well as being a critical component of crop pollination systems worldwide. High mortality rates have been reported in different continents attributed to different factors, including pesticides, pests, diseases, and lack of floral resources. Furthermore, climate change has been identified as a potential driver negatively impacting pollinators, but it is st...

  • > Aerosol source apportionment uncertainty linked to the choice of input chemical components

    For a Positive Matrix Factorization (PMF) aerosol source apportionment (SA) studies there is no standard procedure to select the most appropriate chemical components to be included in the input dataset for a given site typology, nor specific recommendations in this direction. However, these choices are crucial for the final SA outputs not only in terms of number of sources identified but also, and consequently, in the source contributions estimates. In fact, PMF tends to reproduce most of PM ...

  • > Achieving sustainability in family farming

    While small-scale farming households constitute a large part of the population, as well as the producers of the majority of food supplies in low- and middle-income countries, major gaps remain in the ability to produce reliable solutions to achieve sustainability in family farming. This special issue aims to address some blind spots and shed new light on sustainability in family farming using sustainability science. The publications presented in this special issue will enable readers to grasp...
