ICARDA and The Food and Agriculture Organization of the United Nations (FAO) are pleased to announce the launch of a Webinar Series on the Measurement of Actual Evapotranspiration: Basic principles, and measurement methods.

The webinars cover a number of evapotranspiration measurement themes including underlining the time and space scale of measurement applications and analyzing their accuracy and suitability for use in arid and semi-arid environments. Each webinar will include a 45-min lecture by an international expert followed by a 15-min presentation of a regional speaker (except on November 10) and, finally, a 30-min Q&A session with audience.

We will also discuss specific problems of each method for correct application in the MENA region to adapt to climate change, and the increasing scarcity of freshwater for sustainable agriculture.

The webinar Series will also focus attention on state-of-the-art methods for measurement of actual crop evapotranspiration (ETa).

The Webinar Series is part of the FAO-funded NENA Regional ETNet Project led by ICARDA and national partners from Egypt, Jordan, Lebanon, Morocco, and Tunisia.

The webinars will be held on every-other Wednesday from 1500-1730 (GMT +2) starting from September the 15th 2021.

Here’s the line-up of world-renowned experts in the field of ET measurement that are going to speak in the webinar series. Mark your calendars!
