Call for abstracts

The symposium organizers invite authors to submit abstracts for oral and poster presentation under the themes:

  • 1 Current state of organic production in the world: challenges and innovations
  • 2 Organic nutrition (plant): experience, and new directions
  • 3 Challenges of pest and disease control without conventional pesticides
  • 4 Marketing organic bananas: The role of Sustainable Development Goals (SDGs) on certification and emerging trends

Details on what can be included in these themes are elaborated below.

Abstract submission guidelines

The deadline for abstract pre-submission is 6 December 2021.

Submit your abstract by email to the following address: k.lehrer@
IMPORTANT: Please be sure to put “Abstract submission” in the subject of your message and include your contact information in the footer or signature of your email message.

The abstract needs to be submitted as a Microsoft Word or other text file (no PDF). It should not be longer than 300 words. In the header of the Word file, please be sure to indicate to which theme your abstract pertains and whether you intend your paper for oral or poster presentation. Please note that all oral presentations will require the submission of a full paper, which will be published in a volume of Acta Horticulturae. If this is not agreed to by the author(s), the work can be presented as a poster.

You can find the full abstract submission guidelines here:

Review process

All submitted abstracts will go through a review process and authors will be notified if their abstract has been accepted for poster or oral presentation.

Abstracts will initially be prescreened by the Scientific Committee to make sure that they conform to the symposium theme as well as to the session to which they are submitted; no abstract will be considered unless it goes through this first step.

After the prescreening, the authors will be informed about how to submit their abstract(s) to the ISHS via the online interface. If you are already a member of ISHS, the submission charge is waived as part of your membership benefits and you will be prompted to verify your contact details. If you are not a current member of the ISHS you will be required to pay a fee (€95 for European individual, and €80 non-European individual) before submitting your abstract on-line. By paying this fee you will either become a new member of the ISHS or reactivate an existing membership. Please note that as a member of ISHS, there will be a reduction of the symposium registration fee.

Symposium themes

  • Comparison between dry and wet tropics zones
  • Economy gaps on small and larger farms
  • Participatory process, local knowledge
  • Synergies across food systems
  • Healthy diets: Organic Food and Nutritional Quality: role of organic products to human health; is the quality of nutritional value different in terms of comparison of organic to non-organic.
  • Improving livelihoods
  • Socio-economic challenges (e.g. gender) in managing organic banana systems

Session 2: Organic nutrition (plant): experience, and new directions
