Context: Recently, the Amazon, which holds 20 percent of all freshwater in the world, has faced an alarming water crisis, leaving most houses in the region without running water due to a record severe drought.

Key Points of Study

  • Drought in the Amazon has led to historically low water levels in many tributaries, with the main stem of the Amazon river dropping daily, causing a significant transformation of the landscape.
  • Abnormal warming of the Atlantic Ocean, combined with El Niño, is contributing to the severity and potential prolongation of the drought.
  • Experts warn that if the anomalous warming of the Atlantic continues, the extreme drought in the Amazon may persist until mid-2024.
  • The drought is causing a human and environmental tragedy, particularly affecting socio-economically vulnerable populations in the Western Amazon region.
  • Large-scale deforestation, illegal timber exportation, cattle grazing, and soybean plantations have contributed to the loss of water sources in the region, worsening the drought's impact.
  • The Amazon's resilience is at risk, potentially leading to desertification and a point of no return for the rainforest.
