Brazil’s government issued a warning of water shortage in 5 states of the country or insufficient water supply.
On May 28, local time, the Brazilian government announced an early warning issued by the domestic meteorological agency, stating that the five states located in the central and southeastern Paraná river basins of the country may have water supply from June to September this year. Severely bad situation.
The Paraná River Basin is an important agricultural and animal husbandry production area in Brazil and is home to many large hydropower stations. The five states facing the water supply crisis are Mato Grosso do Sul and Goiás in the Midwest, Minas and Sao Paulo in the southeast, and Parana in the south.
According to the information released by the country’s meteorological department, the lack of rainfall in the Paraná River Basin is the leading cause of water shortage. This is also the first time in 111 years that the department has issued a warning about the lack of domestic water supply.
The Brazilian Meteorological Department pointed out that the lack of rainfall or the impact of two atmospheric operating phenomena is an atmospheric phenomenon called “La Nina”, which appeared between October 2020 and March 2021. This phenomenon caused the Pacific ocean waters. The temperature drops and changes the global atmospheric circulation patterns, resulting in reduced rainfall in southern Brazil. The second is from an atmospheric phenomenon called the “Antarctic Oscillation”, which changes the pressure pattern of the Paraná River Basin, which may cause a decrease in rainfall in this area.
In the face of the above situation, the Brazilian Ministry of Mines and Energy held an emergency meeting on the 27th local time and decided to tighten hydroelectric power generation measures to ensure good water sources for the hydroelectric power station reservoirs in the Paraná River Basin to ensure the navigation of ships on the water and provide services to surrounding citizens. Sufficient drinking water. At the same time, all the thermal power plants in this area will be put into operation to ensure that the power supply will not be interrupted.
