What caused the São Paulo drought?
São Paulo’s drying reservoirs The 2014 drought likely resulted from anthropogenic climate change, but the drought was not directly linked to deforestation in the Amazon. The 2021 drought (Figure 3) is similarly a variation augmented by climate change.
When was the last drought in Brazil?
The 2014–17 Brazilian drought is a severe drought affecting the southeast of Brazil including the metropolitan areas of São Paulo and Rio de Janeiro. In São Paulo, it has been described as the worst drought in 100 years.

Why is Brazil in a water crisis?
Intensive cattle farming leads to unvegetated land and compacted soils. As well as decreasing the amount of moisture given off by plants, it limits the soil’s capacity to retain water and recharge aquifers. But droughts alone don’t explain the recurrence of water crises in Brazil.
Why is Brazil in drought?
Worldwide climate change is making droughts more intense and more frequent. Deforestation in the Amazon is a contributor locally and globally. The hydroclimate in the south-central region — the engine of 70% of Brazil’s gross domestic product (GDP) — is partly controlled by moisture transfer from the rainforest.

Why does Brazil not have clean water?
Industrial Effluents: According to the World Bank in 2016, Brazil found industrial effluents, such as heavy metals, in bodies of water. As a result, surrounding rivers are unsafe sources for water and this has forced cities around the region to find water from distant basins and wells.
How did Brazil run out of water?
Brazil suffered one its worst hydro crises in 2001, when a severe drought caused key water reservoirs to drop to critical levels. That forced the government to implement a power-rationing plan that affected individuals as well as industries, particularly the most energy-intensive ones.
