On August 4, 2026, three days before he left office, Colombian President Gustavo Petro signed a resolution placing 186,500 square miles of the Amazon off-limits to any new extraction. That means no new mining concessions, no new oil or gas contracts, and no environmental permits that would make either possible. The deadline was not incidental. Petro’s successor had campaigned on reviving oil exploration and legalizing fracking.

What made this move unusual was the legal mechanism. The government reached back more than 50 years to invoke Article 47 of the Natural Resources Code, a statute that allows the Colombian state to exclude an entire region from private exploitation rights. It had been used before, in smaller pieces, but never applied to the whole Colombian Amazon at once.

What the resolution does and doesn’t do

This is not a national park. It does not fit any existing legal conservation category. What it does, specifically, is prohibit three things: issuing new mining concessions, signing new oil or gas contracts, and granting the environmental permits that accompany either.

Before the resolution was signed, there were 164 active mining titles, 284 pending applications, and 39 active oil and gas contracts; since they are existing operations, they can’t be touched. All of those continue until their contracts expire, but fortunately, what is off limits for them is a renewal. The effect is not an immediate halt but a permanent door closing on anything new.

One narrow exception applies: small-scale extraction of construction materials for local road repair remains allowed, though even that is off-limits within indigenous territories.

The incoming administration

Abelardo de la Espriella took office on August 7, four days after the resolution was signed. During his campaign, he pledged to revive oil exploration and legalize hydraulic fracturing nationwide, describing the practice as modern and responsible. His incoming environment minister has already signaled that fracking will proceed in certain areas.

The new government has not commented on the Amazon reserve specifically, however that silence may not last. Because this is an administrative resolution rather than a law, it is more vulnerable to reversal than legislation would be.

Why the Ministry says this is urgent

The deforestation data the Ministry of Environment cited makes a clear case. Between 2016 and 2023, the Colombian Amazon lost 1.95 million acres of forest, accounting for 60% of all deforestation recorded across the country during that period. Between 2022 and 2024 alone, another 645,000 acres disappeared.

The technical diagnosis points to what specialists call the fishbone effect. When a road is cut to service an extractive project, it branches into side roads that gradually open territory to settlement, illegal logging, and illicit crops far beyond the area originally permitted. The road is not just a road. It is an entry point.

The resolution also rests on a legal foundation that has been building for years. In 2018, Colombia’s Supreme Court recognized the Colombian Amazon as a subject of rights, effectively giving the rainforest legal standing to be protected in its own right. In 2025, the Constitutional Court reinforced that precedent by designating it a specially protected ecosystem.

What indigenous communities cover

Of the total protected area, 55%, or about 66.2 million acres, consists of indigenous reserves. One figure from that land is worth stating plainly: indigenous territories in the Colombian Amazon retain 99.5% of their forest cover intact and hold approximately 78% of all the carbon stored in the region.

Where indigenous communities manage the land, the forest fares better than anywhere else. That is not simply a talking point, there is recorded evidence to support this.

Before signing the resolution, the government consulted the region’s indigenous peoples at a meeting on July 19 and 20. Consultation with Afro-Colombian, Raizal, and Palenquero communities had not yet concluded, so the resolution explicitly states it will not apply to their territories until that process is complete.

What is at stake for water and climate?

The Ministry’s central argument is not about biodiversity alone. It is about water. The Amazon’s roughly 400 billion trees release approximately 20 billion tons of water vapor into the atmosphere every day, a phenomenon researchers call flying rivers. Around 670 million people across Latin America depend on those invisible rivers, which supply much of the moisture that feeds rainfall in Colombia’s eastern mountain range and the high-altitude wetlands that supply Bogotá’s water.

The region also stores an estimated 6.5 gigatons of carbon. Researchers have flagged the risk of a tipping point from which the Amazon could not recover on its own, gradually transforming from rainforest into something resembling savanna. The consequences of that shift would extend well beyond Colombia’s borders.

Colombia is now the strictest of the eight nations that share the Amazon basin, which include Brazil, Peru, Ecuador, Bolivia, Venezuela, Guyana, and Suriname, in its commitment to keeping extraction out of its portion of the forest. Whether that commitment holds will depend entirely on a government that did not sign the measure but inherited it on its very first day in office.
