Brazil, located in South America, is currently suffering from extreme drought. The Amazon River has dried up on a large scale, and the river water level in the Amazon Basin has dropped to a historical low.

According to a report released by the Brazilian National Natural Disaster Monitoring and Early Warning Center, Brazil is currently facing the most severe drought since records began in 1950. Currently, the drought area in Brazil exceeds 5 million square kilometers, accounting for 58% of the country's land area, of which more than one-third of the country is facing "extreme drought." Brazilian meteorological experts said that August to October is usually the dry season in Brazil, but the drought that has continued to this day has broken this rule.

The long-term drought has caused the soil to lose moisture continuously, and the water levels of rivers, lakes and groundwater have continued to decline, which has put tremendous pressure on the reserve and supply of water resources.

The severe drought caused the river water level to drop, the efficiency of hydropower generation to drop significantly, the inland waterway navigation to be partially interrupted, and the pests and diseases to increase, resulting in a decrease in the yield per unit area of citrus orchards, which ultimately led to a sharp drop in the country's citrus production. Sao Paulo State and Minas Gerais State are the main citrus production areas in Brazil, but in the second half of last year, these areas experienced 11 consecutive days of extremely high temperatures exceeding 35°C. In addition, the large-scale prevalence of Huanglongbing caused a sharp drop in the production of citrus in the main production areas.
