International Conference on Crop Losses

An International Conference on Crop Losses caused by diseases, pests and weeds will be held in Paris from 16 to 18 October 2017. The aim of this conference is 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 will bring 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.

Rationale and aim of the Conference

Plant diseases, pests, and weeds negatively affect crop health, with large effects on crop performances, ecosystems, and society. Crop health also plays an important role in the complex links between agriculture, food security, and global change. Quantification of these negative impacts is often fragmented or incomplete.
Approaches are needed to characterize the risks associated with shifts in crop health in response to global changes, new policies, or new technology. Conversely, approaches are also needed to document the potential gains that could be achieved through better, improved, or more efficient crop health management.
Understanding the causes of crop losses and their quantification is necessary to compare production systems and crop health management strategies in view of their improvement. Assessing and modelling crop losses to diseases, pests, and weeds can inform long-term strategic decisions, research prioritization, and national or international policies. Programme here.

This international conference will address the following questions

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

With the practical implication

  • Can we establish a global, open-source database on crop losses, which will help answer these questions?

Through two phases

  • A series of keynotes presented by world experts in the field
  • A series of Work Group Sessions where participants will discuss concepts and their practical implementation

This Conference is held at the initiative of INRA in close partnership with Cirad and the international networks AgMiP and MacSur.
