International Conference on Global Crop Losses Caused by Diseases, Pests, and Weeds

An international conference on global crop losses was organized by Inra in Paris on three days (October 16 - 18, 2017).  The aim of this conference was to assess how plant diseases, pests, and weeds negatively affect crop health, crop performances, ecosystems and society. Although these negative impacts are well recognized, their quantification is still fragmented or incomplete.

The conference brought together key players in global agricultural and crop health research in order to explore and discuss opportunities related to analyzing, quantifying, and modelling crop losses to diseases and pests.The conference involved some 80 participants from 20 countries.

The event was organized by INRA, through its Flagship Meta-Programs SMaCH (Sustainable Management of Crop Health) and GloFoodS (Transitions to Global Food Security), in partnership with Cirad and the ISPP  and support from the international networks AGMiP and MacSur. See details below.

Key questions addressed by the conference were:

  • What are the effects of diseases, pests, and weeds, on crop performances?
  • How can we understand, quantify, assess, and model these effects?
  • How and what can modelling contribute in the assessment of the impacts of diseases, pests, and weeds, especially on food security?
  • What could be the effects of climate and global changes on crop losses caused by plant diseases, pests, and weeds?

Eight keynotes were presented to address different aspects of crop loss quantification, modelling, and understanding:

  • Impacts of disease and pest crop losses on crop yields and agrosystem performances (K. J. Boote, University of Florida, USA)
       > See the slide show here.
  • Overview of approaches to quantify and model disease and pest losses (S. Savary, INRA, France)
       > See the slide show here.
  • Economic implications of disease and pest losses – modelling and analytical approaches (J. Antle, Oregon State University, USA)
       > See the slide show here.
  • Plant diseases in a changing climate, approaches to assess and estimate future crop risks (A. Von Tiedemann, University of Göttingen, Germany)
       > See the slide show here.
  • Pests and diseases data in the context of yield gaps – the Global Yield Gap Atlas (M. van Ittersum, Wageningen University, The Netherlands)
       > See the slide show here.
  • Linking crops with pests and diseases (K. C. Kersebaum, ZALF, Germany)
       > See the slide show here.
  • Past and ongoing experiences in developing open source online scientific data bases (A. Nelson, University of Twente, The Netherlands and J. Koo, IFPRI, USA)
       > See the slide show here.
  • Importance of disease and pest losses on key world crops – priorities (L. Willocquet, INRA, France)
       > See the slide show here.

> See the extended abstracts here.

These keynotes provided the background for three work groups, which addressed the themes of "Crop Loss Definition", "Models for Crop Losses", and "Data: Sources and Sharing". Work conducted in each of these work groups will lead to a series of reports, including a white paper on crop loss data ontology.
