Holder of one-fifth of the world’s fresh water, the Amazon is beginning the dry season with many of its rivers already at critically low levels, prompting governments to anticipate contingency measures to address issues ranging from disrupted navigation to increasing forest fires.

“The Amazon Basin is facing one of the most severe droughts in recent years in 2024, with significant impacts on several member countries,” stated a technical note issued Wednesday by the Amazon Cooperation Treaty Organization, which includes Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname and Venezuela.
