“Worst Drought” in Brazil.

Brazil's most populous region facing worst drought in 80 years.

Environment Minister Izabella Teixeira said the country's three most populous states are experiencing their worst drought since 1930.

And the other states of Minas Gerais, Rio de Janeiro and Sao Paul must save water, she said after an emergency meeting in the capital, Brasilia.

Ms. Teixeira described the water crisis as "subtle" and "worrying".

The water crisis can be affected on industry and agriculture. And it could badly damage the Brazil’s economy.

The drought has also an impact on energy supplies because it has reduced the generation of electricity from hydroelectric dams and from other means of generation.
