Amazon River: Importance and Size

AMAZON RIVER DRYING: CAUSES AND IMPACTS OF THE SEVERE DROUGHT

1. What Is the Amazon River and Why Is It Important?
• The Amazon River is the largest river in the world by volume, flowing through South America and covering over 7,000 kilometers. It originates in the Peruvian Andes at an elevation of 5,598 meters and makes its way through the Amazon rainforest, ultimately emptying into the Atlantic Ocean. The river is known for its vast size, which varies with the seasons; it spans 4 to 5 kilometers wide during the dry season and can swell up to 50 kilometers during the wet season. The Amazon River plays a crucial role in the global ecosystem, supporting one-sixth of the world’s freshwater and housing an immense diversity of plant and animal life.

2. Why Is the Amazon River Drying Up?
• The Amazon River is drying up primarily due to severe droughts driven by climate change, deforestation, and altered rainfall patterns. Rising global temperatures have intensified weather extremes, causing prolonged dry seasons with below-average rainfall. Deforestation reduces the forest’s ability to release moisture into the atmosphere, disrupting the water cycle and decreasing rainfall. Additionally, El Niño events can worsen drought conditions in the region, further lowering water levels and exacerbating the river’s descent.

3. How Does the Amazon River Contribute to the Global Ecosystem?
• The Amazon River is the largest river by volume and a crucial component of the global water cycle. It contributes about one-sixth of the world’s freshwater that flows into the oceans. The river supports one of the richest biodiversity hotspots on the planet, housing countless species of fish, mammals, birds, and plants.

4. What Areas Are Most Affected by the Drought?
• The drought has severely affected regions such as Tabatinga, Tefe, and Manaus in Brazil, where the Solimoes River, a major Amazon tributary, has reached record low levels. Some branches have completely dried up, turning navigable waterways into sandbanks and affecting local communities and wildlife.
