5 keys to understanding the historic floods in Brazil

Floods in Brazil cause unprecedented chaos. This environmental disaster is the result of a combination of different natural and human factors. Below we present five keys to understanding the most shocking aspects of the floods in southern Brazil.

The Brazilian state of Rio Grande do Sul is facing an unprecedented ecological disaster. As a result of the record flooding, people were killed and missing, thousands of homes were destroyed and roads were cut off.

But Brazil is only one of the many countries that suffer environmental disasters of great magnitude and without historical precedents to match them.

Why do such events occur? Here are 5 points that will help you understand why there are floods in Brazil.

Climate change and other factors: what aggravates flooding in Brazil?

This year is not the first time that a climate disaster has been recorded. Among the controversial floods that affected Dubai and its surrounding areas, as well as the floods in Kenya, the climate crisis is taking center stage and showing the need for urgent action to mitigate climate change.

Among the factors that increase the frequency and intensity of these ecological disasters, there are five that are key to understanding these events:

Climate change: Phenomenon caused mainly by the burning of fossil fuels, which generates an increase in global temperatures. This produces more evaporation of water, then affects the hydrological cycle, resulting in a shorter rain in a shorter time. Therefore, the soil and rivers quickly become saturated, causing flooding.

Rising sea levels: The melting of glaciers has caused sea levels to rise, increasing the risk of flooding in coastal areas.

Deforestation: La deforestation, a common practice in the Brazilian Amazon, reduces the soil's ability to absorb rainwater.

Urbanization: Replacing green spaces with hard surfaces such as asphalt and cement reduces the land's ability to absorb water, increasing the risk of flooding.

Inadequate drainage infrastructure: The lack of effective drainage systems in cities increases the risk of flooding.

Southern Brazil faces worst floods in history

"We are experiencing in Rio Grande do Sul the worst moment, the worst disaster in our history and, unfortunately, it will get worse”, stated the governor of Rio Grande do Sul.

More than 844.000 people suffered total flooding of their cities, the destruction of bridges and the evacuation of homes. Of them, 134.300 people lost their homes.

Current flood situation in Brazil:

  • More than 100 people died: Official figures speak of 108 fatalities, but it is estimated that the number could be higher due to the number of missing people.
  • 136 people missing: Search and rescue teams continue to work hard to find the missing, but adverse weather conditions are making operations difficult.
  • More than 11 million people affected: The floods have impacted four-fifths of the state of Rio Grande do Sul, where around 11 million people live.
  • Widespread devastation: The floods have caused widespread damage to homes, infrastructure, crops and livestock. Economic damages are estimated to run into billions of dollars.

Impact of floods in Brazil:

  • Humanitarian crisis: The floods have caused a serious humanitarian crisis, with thousands of people losing their homes and livelihoods. Food, clean water, shelter and medical care are urgently needed.
  • Damage to the economy: The floods have had a significant impact on the local economy, affecting agriculture, tourism and commerce. It is estimated that it will take the state years to recover from the disaster.
  • Environmental impact: The floods have also caused damage to the environment, polluting rivers and affecting wildlife.
