The 9th International Conference on Biological Invasions will take place from 14th to 16th September 2016 in Vianden (Luxembourg).
Biological invasions are one of the components of global change, causing dramatic impacts on biodiversity and ecosystems. NEOBIOTA 2016 will provide an international high-level forum to discuss how invaders respond to environmental change and their feed-backs. For more details, click here.
The first national day of air quality in France was held on September 25, 2015. It was one of the actions of the roadmap of the environmental conference in 2014, whose purpose was to involve citizens on air quality.
In this context, the RNSA (French Aerobiology Network) held an information stand on pollen and ragweed in Croix Rousse in Lyon (cf pictures below)!
A hundred people passed through the stand and many documents about allergies, pollens, air quality and ragweed have been handed out.
It was a good opportunity to communicate with the general public about the content of the air in biological particles, and to give some information about their health impact.



In the framework of the 2015 International Ragweed Day, EAACI, EAS, EFA and IRS made a press release to alert people and health authorities that more Europeans will be allergic to ragweed pollens if no measure is taken to reduce exposure.
What is ragweed? Why worry? What do we know? What can you do?
Please find all the answers to these questions in this leaflet prepared by the International Ragweed Society for the 2015 International Ragweed Day.
