Some rivers in France have almost dried up, and farmers' harvest has dropped sharply. What effect does high temperature have on farmers' lives?

Like most European countries, France was deeply affected by extreme high temperature in 2022. Extreme high temperature weather not only brought great troubles to the ordinary life of French people, but also caused many rivers in France to almost dry up, which brought great adverse effects to the economic development and agricultural development in some parts of France. The impact of high temperature on farmers' lives is mainly reflected in the fact that the crops planted by farmers will greatly reduce production, which will also lead to a decrease in farmers' income.

High temperature will evaporate a lot of water on the earth's surface, which will greatly reduce the water contained in the soil where crops are planted. Then, in the normal growth of crops, adequate water is essential. If water is scarce, crops may grow slowly and have low seed setting rate. In this case, farmers can only adopt the method of increasing irrigation intensity for crops, which will greatly increase the cost of farmers' investment in crop planting.

Moreover, even if farmers irrigate crops, the normal growth of crops is likely to be greatly affected by high temperature, and finally the crop harvest that farmers can get will be greatly reduced. Therefore, high temperature will greatly adversely affect the profits of farmers. The harm of high temperature weather to rice is very obvious. In a certain period of rice growth, if it suffers from continuous high temperature weather, the leaves of rice will prematurely age and turn yellow. This will make the rice mature prematurely, and at this time, the fruit of rice has not developed well, which will greatly reduce the yield of rice, and many rice will have empty grains. At the same time, high temperature will also inactivate chlorophyll contained in plant mesophyll cells, thus making the photosynthesis of plants unable to function normally.
