Climate Change Impact on Water Consumption and Water Productivity of Crops: Update on recent findings
Hybrid Event, 16/10/2022
A side event during Cairo Water Week 2022
Date: 16 October 2022
Time: 14:00 – 15:30 (Cairo Time)
Leaving apart extreme events (e.g., drought, floods, heat waves, etc.), it is expected that Climate Change (CC) will impact crop performance mainly through two mechanisms which would affect both ‘evapotranspiration’ (ET) and ‘productivity’ in opposite directions: increased temperatures and increased atmospheric CO2 concentrations.
This Technical Session will first review the most valuable experimental results conducted in closed and open field, both at international level and within the NENA Region, where temperature and CO2 treatments are compared. Then it will discuss what would be the likely expected crop response to these two CC variables, accounting for the interaction with other environmental factors (e.g., water and nutrients). Finally, it will draw some inferences about what to expect in terms of ET and CWP changes in the near- and mid-future.
The session will provide the opportunity to present the FAO Report on the “Remote Sensing Determination of Evapotranspiration” that synthesizes the results of 24 webinars and a dialogue process concluded at the CWW-2021.
This Technical session is organized in the context of the Regional Water scarcity Initiative and its regional project WEPS-NENA “implementing the 2030 Agenda on efficiency, productivity, and sustainability for water in the NENA region.
