Heavy rains, heatwaves, droughts… climate events are endangering agricultural yields, according to Philippe Lehrmann, an agronomy expert. He explains that even occasional phenomena can alter the development of plants with long-term repercussions. For example, a spring heatwave reduces the number of ears per square meter, while a stormy episode affects the grain quality.
Over the long term, the global agricultural landscape is being modified, with crops disappearing in the Sahel region, while other regions experience longer periods of favorable humidity for cultivation.
The degree of climate impact on yields also depends on the growth stage of the plant at the time of the climate event.
Any potential shortages are generally offset by global trade.
