Résumé : Rice yield can be reduced substantially when the crop is exposed to excessive hest, which will likely occur more frequently under future climates, but the magnitudes of yield losses under open-field conditions are still difficult to predict, despite many efforts being conducted to detennine temperature response in the closed environments. To better understand the occurrence of heat stress under field conditions. we need thermal conditions of rice canopy under heat conditions, which can be very much different depending on other environmental factors, but taking correct measurements of canopy micrometeorology needs careful considerations. In this study, we will distribute a simple but well-designed system for measuring thermal environments of the canopy to different rice growing regions covering continental and coastal climates in low and mid latitude regions. With them, we attempt to establish a monitoring network of canopy thermal environments in the paddy fields that will help to bridge gaps between chamber and open-field and to better assess potential impacts of climate change on rice production.
