With each degree of global warming, monsoons are likely to increase by 5%, according to one of the key points of the analysis.
While more rain seems like a good thing, too much (or too little) can damage the crops. India relies on this seasonal rainfall to get the crops it needs to feed the world’s second largest country. However, the authors suggest that climate change will have a negative impact on their agriculture if it is left unabated.
It is not just an increase in monsoon rainfall that this study suggests, but variability as well.
This includes longer periods of drought, when rain is most needed.
A “more chaotic” and “more unpredictable” future lies ahead of us
For example, rice, an important food source on the Indian subcontinent, is very sensitive to changes in rainfall. Plants need rainfall, especially during the initial growth phase. But too little or too much at once can damage the plants.
“The problem with the increased variability, however, is the reduced predictability, which makes it difficult for farmers to deal with the monsoons,” Levermann, who is affiliated with the Potsdam Institute, told CNN.
Agricultural policy expert Devinder Sharma told CNN that agricultural practices will have to adapt to this climate variability, but how exactly this will remain remains unknown.
“We don’t know how climate change will affect us. It could be heavy rain at some point, followed by drought or hurricanes. It will not be uniform. This will cause the agricultural sector and many problems as well.” for the economy. “
The story underlines the influence of humans on the intensification of precipitation
“Among the unabated climate change, the CO2 effect is by far the strongest effect and the change in the monsoons will dominate over all natural and other man-made effects,” says Levermann.
