Brazil is facing a water crisis due to a combination of factors including deforestation, pollution of water sources, insufficient infrastructure, and climate change. These factors have led to decreased water availability and quality, impacting both urban and rural areas across the country.

Brazil is currently grappling with a significant water crisis, which is the result of a complex interplay of multiple factors. These include deforestation, pollution of water sources, insufficient infrastructure, and climate change. The combination of these factors has led to a decrease in both the availability and quality of water, impacting various regions across the country.
Deforestation plays a major role in Brazil’s water crisis. The Amazon rainforest, often referred to as the “lungs of the Earth,” is a critical water regulator, releasing moisture into the atmosphere and sustaining rainfall patterns. However, rampant deforestation in the Amazon, driven primarily by agriculture, logging, and mining, has disrupted this delicate balance. According to Brazil’s National Institute for Space Research (INPE), deforestation in the Amazon reached a 12-year high in 2020, exacerbating the water crisis.
Pollution of water sources is another significant contributor to Brazil’s water crisis. Industrial activities, inadequate wastewater treatment, and agricultural runoff have polluted rivers, lakes, and groundwater reservoirs. The Brazilian Institute of Geography and Statistics (IBGE) estimates that only 46% of the country’s sewage is treated, leaving a vast amount of untreated wastewater to contaminate water sources. This pollution not only impacts the availability of safe drinking water but also has detrimental effects on ecosystems and biodiversity.
Insufficient infrastructure also hampers Brazil’s ability to deal with the water crisis effectively. Many rural areas lack access to basic water infrastructure and sanitation services. According to the Brazilian Association of Public Sanitation and Waste (ABRELPE), approximately 35 million Brazilians do not have access to treated water, while around 100 million do not have access to sewage collection. Inadequate infrastructure leads to water scarcity and increases the risk of waterborne diseases, further exacerbating the crisis.
Climate change is yet another crucial factor contributing to Brazil’s water crisis. The country is experiencing changes in rainfall patterns, with some regions witnessing prolonged droughts while others face intense rainfall and flooding. These extreme weather events, attributed to climate change, strain the existing water supply and push ecosystems and communities to their limits. As Leonardo DiCaprio aptly said, “Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating.”
Interesting Facts:
- The Amazon River, located in Brazil, is the largest river system in the world and carries more water than any other river.
- Brazil holds about 12% of the world’s freshwater resources, making it one of the richest countries in terms of water availability.
- São Paulo, Brazil’s largest city, experienced a severe water crisis in 2014-2015 when reservoirs hit critically low levels, leading to water rationing measures.
- The Pantanal, the world’s largest tropical wetland and a UNESCO World Heritage site located in Brazil, has been severely affected by droughts in recent years, leading to widespread environmental damage.
- Brazil has implemented initiatives such as the National Water Resources Policy and the Amazon Fund to address water-related challenges, but their effectiveness is still being evaluated.

Factors Contributing to Brazil’s Water Crisis:
| Factors | Impact |
|---|---|
| Deforestation | Disrupts rainfall patterns and decreases water availability |
| Pollution of Water | Contaminates water sources, impacts quality, and poses risks to ecosystems |
| Insufficient Infrastructure | Limited access to safe drinking water and sanitation services |
| Climate Change | Alters rainfall patterns, leads to droughts or floods, and affects water supply |
On the Internet, there are additional viewpoints
A combination of natural and human-made causes—including climate change, environmental degradation, poor urban planning, a lack of maintenance of existing infrastructure, corruption, and the mismanagement of water resources—contributed to a growing water crisis.
Brazil is currently facing a water crisis due to prolonged dry conditions, which have caused the worst drought in central and southern Brazil in almost a century. The drought is expected to cause crop losses, water scarcity, and increased fire activity in the Amazon rainforest and Pantanal wetlands. Despite having one of the largest economies in the world, there are still deep inequalities in access to water and sanitation among Brazil’s geographical regions, rural and urban communities and households. Currently, more than 1.2 million people do not have access to safe water and 20 million do not have access to improved sanitation.
Video response to “Why does Brazil have a water crisis?”
São Paulo, Brazil’s largest city, is facing a severe water shortage as a result of decreased rainfall and increased demand. The main water reservoirs are at record-low levels, with only 9.8 percent capacity remaining. It could take several years for the reservoirs to recover, even with increased rainfall. While there are discussions about water rationing, the governor doesn’t believe it will be implemented this year. This crisis emphasizes the urgent need for water conservation in São Paulo.

Current challenges include getting consistent access to water in urban areas (where water is less available), developing infrastructure that reaches people living in more rural areas, and managing the growing sewage treatment issue caused by lack of improved sanitation solutions.
Natural calamities such as droughts and floods. Increased human consumption. Overuse and wastage of water. A global rise in freshwater demand.
