Agriculture is one of the areas most sensitive to changes in climate change. Affected by climate warming, China's agricultural production layout and planting structure have undergone changes, and a series of chain reactions such as a substantial increase in agricultural costs and investment will inevitably emerge gradually. According to relevant experts from the Chinese Academy of Agricultural Sciences, if effective measures are not taken, by 2030, the productivity of China's crop production may decline by 5% to 10% due to climate warming, among which the three major crops of wheat, rice, and corn will decline. The impact will be greater after 2050. This is not an expert alarmist.

Complex climate will affect the agricultural market
Climate warming will also accelerate the release of fertilizers, resulting in a decline in soil fertility. The application of pesticides and fertilizers will continue to increase.
According to relevant experts, when the temperature rises by 1 degree Celsius, the amount of nitrogen released will increase by about 4%, and the release period will be shortened by 3.6 days. To maintain the original fertilizer efficiency, the amount of fertilizer applied each time needs to be increased by about 4%. The increase in the amount of fertilizers not only increases the input of farmers, but also increases the loss of volatile, decomposing, and leaching of fertilizers, which is also harmful to soil and the environment. In addition, climate change will also change the layout of China's major crop varieties, such as the northern boundary of the winter wheat cultivation area will move north.
Experts suggest that we should start reducing the impact of climate change on agriculture in four areas.
The first is to strengthen agricultural infrastructure construction and basic farmland construction, promote dryland water conservation technologies, increase agricultural disaster prevention, disaster prevention, disaster reduction, and comprehensive production capacity; second, establish and improve the early warning mechanism for agricultural disaster prevention and reduction; third, adjust the agricultural layout and rationalize Planning agricultural arable land to enhance the resistance and recoverability of the agricultural production system; fourth is to cultivate and popularize high-yield, high-quality, drought-resistant, glutinous-tolerant, high-temperature-resistant, disease-resistant insect-resistant and other fine varieties, and improve coverage of improved varieties.
