Other claims from this paper (10)
- Association Air temperatures above 27 C were associated with decreased rice brown spot prevalence.
- Association Wind speeds exceeding 1 m/s were associated with decreased rice brown spot prevalence.
- Association Relative humidity above 80% significantly promoted rice brown spot development.
- Association Wet bulb and dew point temperatures between 23 C and 27 C significantly promoted rice brown spot development.
- Observation Rice brown spot severity increased yearly, ranging from 2.47 to 3.46 on a 0-5 scale.
- Association Rice brown spot prevalence was consistently higher during the rainy seasons.
- Observation Predictive modelling suggests a likely expansion and intensification of rice brown spot risk in the future.
- Observation Under a high-emission scenario, rice brown spot severity could reach 4.9 by the late 21st century.
- Observation Under the moderate scenario, rice brown spot is projected to peak at severity 4.33 between 2060 and 2080.
- Recommendation The authors conclude there is an urgent need for climate-adaptive disease management strategies to sustain rice production in Africa.
