Amidst the relentless grip of historic droughts, vast expanses of South America find themselves teetering on the edge. Hydroelectric dams, once beacons of renewable energy, now falter under the soaring demand, while the Amazon—a once-thriving ecosystem—battles a conflagration that spreads rapidly through its beleaguered flora.
As nearly 200 nations converge in the tropical heart of Cali, Colombia for the UN COP16 biodiversity summit, the echoes of climate change crescendo, intensifying the frequency and ferocity of extreme weather phenomena. In Bogotá, famously known for its typically abundant rainfall due to its lofty elevation, residents are now all too familiar with the sound of water rationing—a bittersweet symphony that has played daily for much of this year.
An illuminating report, crafted by a coalition of international scientists, established earlier this year an unsettling truth: the exceptional drought gripping the Amazon Basin since 2023 is, fundamentally, a child of climate change. This sprawling basin extends its reach across the central and eastern flanks of South America, touching Colombia to the north, curling around Peru and Ecuador to the east, cradling Guyana and Suriname to the west, and stretching down to Brazil and Bolivia in the south.
In the face of dwindling water reserves, Colombia has made the strategic decision to cease electricity exports to its neighbor, Ecuador, as it strives to preserve its own dwindling supply. Ecuador finds itself in a precarious predicament; nearly 80% of its energy portfolio is drawn from hydropower, and the worst drought in six decades has lockstep ushered in stringent electricity rationing. The capital city, Quito, previously bustling with life, now grapples with scheduled blackouts stretching up to eight hours, a grim reality that could soon escalate to an astounding 14 hours a day.
To stave off the impending crisis, Ecuador has enlisted the aid of a barge-mounted 100MW power plant from Turkish conglomerate Karpowership—yet this fortuitous addition only alleviates a meager fraction, about 10%, of the national energy deficit that hovers ominously around 1,000MW.
Predictions cast a shadow over the nation’s energy landscape, foreseeing that the current crisis—forever fueled by parched reservoirs—will linger until at least January. The implications extend beyond mere inconvenience; they could ripple through the political sphere as President Daniel Noboa prepares for re-election next year, recently taking the step to appoint Inés Manzano as the interim energy minister, a dual-role holder who also oversees environmental affairs.
Weather patterns, too, join the tumultuous saga. Cristian Paliz Acosta from INAMHI, Ecuador’s meteorological agency, points to a stirring in the Walker circulation over the tropical Pacific. This shift, wherein warm, moisture-laden air ascends in the west, while its cooler, drier counterpart descends in the east, disrupts rainfall across South America. “This intensification serves to suppress precipitation—not just here, but across broader Latin America,” Paliz reflects, revealing that the past 30 days have seen rainfall levels barely scraping 10 to 50 percent of their usual bounty.
In the Brazilian Amazon, the situation escalates further as submerged river systems succumb to historic lows. Manaus, a city nestled within this lush rainforest, recorded its lowest water level in over a century, a devastating milestone that eclipsed even the previous year’s lows.
The repercussions resonate deeply; essential river traffic has come to a halt, isolating remote communities and depriving them of vital resources. This year’s traditional rainy season, so often a harbinger of rejuvenation, faltered, giving rise to a catastrophic increase in wildfires—10 million hectares consumed in Bolivia and 7 million in Brazil, as reported by the Inter-American Association for Environmental Defence. September bore witness to an air thick with pollution, a testament to nature’s anguish.
Peru’s government, recognizing the urgent need for intervention, declared a state of emergency for 60 days in its Amazon provinces flanking Ecuador and Brazil, areas ravaged by relentless fires. Clair Barnes, a researcher from the Grantham Institute, encapsulated the dire situation succinctly: “The unending heat, coupled with scant rainfall, has transformed these once-thriving ecosystems into scorching cauldrons of flammable vegetation.”
Indeed, the narrative unfolding across South America paints a vivid portrait of struggle—a landscape irrevocably altered in the face of climate adversity, where nature’s resilience hangs in the delicate balance of survival.
