    Groenekennis - Informatie voor professionals in voedsel en groen

    Groenekennis bevat artikelen uit vaktijdschriften, rapporten, video’s, presentaties, posters en websites op het gebied van landbouw, visserij, groene ruimte en voeding. Groenekennis wordt dagelijks bijgewerkt en bevat ongeveer 500.000 bronnen.

    Groenekennis is de globale view over diverse deelbestanden. Groenekennis is gevuld met alle informatie uit Groen Kennisnet, de Hydrotheek, Tuinpad, IB archief, ARTIK, bioKennis, Kennisbank Plantaardige bronnen, Kennisbank Zeldzame landbouwhuisdieren en afgesloten documentatiebestanden zoals Land Bodem Water en Consumenten- en huishoudstudies.

    Groen Kennisnet is een zeer belangrijk onderdeel van Groenekennis. De doelstelling van Groen Kennisnet is kennis delen op het gebied van Voedsel en Groen te bevorderen en te faciliteren voor een breed publiek.

    Bronnen in Groenekennis kunnen direct opgevraagd worden via een geavanceerde zoekmachine met een 'google-achtige' interface. Met filters kan ingezoomd worden op diverse aspecten, zoals Trefwoord, Collectie, Jaar en Auteur. Bovendien biedt Groenekennis gebruikers de mogelijkheid om via de E-mail geattendeerd te worden op aanvullingen in specifieke vakgebieden.
    De Tijdschriftenlijst biedt een overzicht van tijdschriften waaruit de artikelen voor Groenekennis worden geselecteerd. Door te klikken op een titel krijgt u alle artikelen uit dat tijdschrift in de Groenekennis database getoond.
    Zoeken op kaart biedt een geografische ingang op de beschikbare publicaties over de binnen dit bestand onderscheiden gebieden.

    Groenekennis is onderdeel van het bibliotheeksysteem van WUR. Praktijkgerichte publicaties en rapporten van WUR komen daardoor automatisch beschikbaar. Daarnaast wordt de database doorlopend gevuld met voor het groen onderwijs bruikbare bronnen en artikelen, video’s en websites. Het percentage online is de laatste jaren gegroeid tot tweederde van de totale aanwas per jaar. Dit percentage groeit nog steeds.
