What was once a millionaire's extravagance during the golden age of Colombian drug trafficking has now become one of the the most publicized environmental conflicts on the planetThe famous hippos that Pablo Escobar brought to his Hacienda Nápoles have taken over rivers, towns and headlines, benefiting scientists, politicians, neighbors and animal rights activists.
Although the phenomenon originated in Colombia, the debate has crossed borders and is being followed with interest from Europe and Spain, where the case is cited as an extreme example of what happens when wildlife trafficking and lack of control are mixed with organized crime. The possible relocation of some of these animals in India It has added an international dimension that further complicates the situation.
From Escobar's private zoo to an out-of-control population
During the height of the Medellín Cartel's expansion in the late seventies and early eighties, Pablo Escobar built the famous [unclear] in Doradal (Antioquia). Hacienda Nápoles, an estate of more than 2.000 hectares with artificial lakes, runways and, as a symbol of its power, a zoo teeming with exotic animals brought in illegally from Africa and other continents.
Among the dozens of African species Among the animals that gathered – giraffes, elephants, rhinoceroses, lions, and ostriches – a small group of hippos stood out: one male and three African femaleswhich the drug lord imported around 1981 to fatten his own personal "Noah's Ark". Nobody imagined then that those four animals would end up being the protagonists of a national environmental crisis.
After Escobar's death in 1993, the state seized the ranch. Many of the large mammals were sent to zoos and reserves in Colombia and other countries; some were sold, and others simply disappeared through looting and neglect. The hippos, however, were left to their fate.wandering around nearby ponds and lagoons without a clear management plan.
Over time, several specimens escaped from the enclosures of the old farm and reached the Magdalena River basin, a humid and fertile region that, in practice, offered them conditions similar to those of their original African habitatsbut without natural predators to limit its expansion.
In a matter of decades, the small herd transformed into a population estimated today at around 200 semi-wild hipposScattered across approximately 43.000 square kilometers, according to calculations by the Colombian Ministry of Environment. Scientific projections warn that, without decisive action, their population could exceed 500 individuals by around 2030, and reach between 1.000 and 1.500 animals by 2035.
From tourist attraction to invasive species and ecological threat
For years, the image of these giant mammals grazing in lagoons or crossing roads fueled a certain folklore surrounding the “cocaine hippos”"These are the nicknames by which they are popularly known in Colombia." In Doradal, many residents considered them unofficial mascots of the town, part of the landscape, and, incidentally, a top-notch tourist attraction.
The former Hacienda Nápoles, now a theme park, includes tours to see these animals, which has generated a constant flow of national and international visitorsFor an area historically marked by violence and lack of opportunities, hippos became a symbol of identity and a significant source of income.
However, behind that picturesque image lies a serious problem. Scientists have been warning for years that the characteristics of the hippopotamus This causes the species, when introduced without control, to... alters the dynamics of aquatic and riparian ecosystemsTheir movements cause erosion on the banks, their excrement alters the water's chemistry, affects fish populations, and could displace native fauna such as manatees or capybaras in feeding areas.
There is also concern about people's safety. Although serious incidents in Colombia have been few and far between—such as the attack on a farmer in 2020, which resulted in several broken ribs, or the collision of a vehicle with a hippopotamus on a highway between Medellín and Bogotá in 2023—the African reference is clear: The hippopotamus is considered one of the most dangerous animals on the continent., responsible for numerous deadly attacks each year.
That less pleasant side of the phenomenon led the Colombian government to Declare hippos an invasive alien species in 2022From then on, the debate ceased to be just a journalistic curiosity and became a matter of national environmental policy.
The State's responses: sterilization, failed transfers, and euthanasia
Before resorting to drastic measures, the authorities spent years trying less controversial alternatives. They opted for Reproductive control programs, such as surgical castration and chemical sterilizationas well as exploring possible transfers of specimens to zoos or reserves abroad.
The problem is that capturing and sedating an animal that can easily exceed 1.300 kilos is no easy task. Teams of biologists and veterinarians have explained that Each sterilization operation can take up to eight hours and requires the coordination of at least eight people, with a very high cost per individual in relation to available budgets.
Attempts at international relocation have also not been particularly successful. Although moving hippos to other interested countries has been considered on several occasions, Logistical costs, health requirements, and procedures under the CITES Convention They have halted most of these initiatives. In the end, the population has continued to grow at a rate faster than the authorities could control.
Faced with this scenario, and with projections pointing to hundreds of copies in just a few years, the government decided to change course. In April, the Colombian Executive approved a plan to euthanize 80 hipposwith a budget of nearly two million dollars. The roadmap includes both lethal injections and the possibility of shooting some animals in the head, always under official protocols.
This decision has sparked controversy. Scientists and conservation experts who defend euthanasia as the lesser of two evils have denounced it. pressures and personal threats from sectors opposed to the sacrificeMeanwhile, animal rights organizations are calling the measure outright "murder" and demanding solutions based on relocation and reproduction control.
Vantara's role: promises of rescue and shadows of doubt
In the midst of this polarized climate, an unexpected actor appeared: Vantara, a gigantic wildlife rescue and conservation center in Jamnagar, in the Indian state of Gujarat, driven by billionaire Anant Ambani, heir to the richest man in Asia.
At the end of April, the sanctuary sent a formal request to Colombian authorities to reconsider the euthanasia of the 80 hippos planned by the government. As an alternative, He offered to receive those animals at his facilities, assuming the costs of the transfer. and committing to integrate them into a controlled environment where hundreds of elephants, felines and reptiles already live together.
The proposal coincided with the announcement by the Colombian Ministry of Environment that it would study any viable option to avoid mass culling, without, however, ruling out euthanasia as a management tool. Minister Irene Vélez made it clear that the official strategy includes a dual protocol: population reduction through culling and relocation, with the idea that both approaches are applied simultaneously and in a complementary manner.
To move forward with the eventual transfer, the Colombian government sent its Indian counterpart a formal inquiry regarding the legal feasibility of the operation and compliance with the requirements of the CITES Convention, which regulates the international trade in endangered species. Simultaneously, an agreement was reached on Arrival in Colombia of a delegation of experts and veterinarians from Vantara, responsible for assessing the condition of the hippos on the ground and collaborating on a possible logistical plan.
However, the supposed “sanctuary” that was presented as a lifeline for Colombian hippos has begun to raise questions. Journalistic investigations in several countries, including Brazil and Venezuela, as well as reports from international organizations, have focused on Vantara's transparency and its possible links to wildlife trafficking.
International investigations and suspicions surrounding the Indian sanctuary
One of the main controversies revolves around Tony Silva, American ornithologist convicted in the 1990s for smuggling exotic birds endangered. According to investigations by the Brazilian Federal Police and reports from media outlets such as Mongabay and Armando.info, Silva is once again under scrutiny for a possible role in animal trafficking networks, including cases related to lion-headed marmosets.
In this context, various indications have professionally linked Silva to Vantara. At an international conference held in Thailand, He was publicly introduced as the "conservation leader" of the Indian centeracting as the sanctuary's representative to specialists and NGOs. Photographs and social media posts reinforced this image of collaboration.
When questioned by the press, activists and conservation experts in Brazil confirmed that There was a working relationship between Silva and Vantaraat least in technical advisory roles. However, the Indian center issued a statement denying any “direct connection” with the ornithologist and asserting that, if anything, it may have collaborated with an independent consultant who had worked with him in the past.
According to Vantara's official version, Tony Silva's travels and activities would be his sole responsibility.with no connection whatsoever to the sanctuary. The organization claims it had no knowledge of his trips to Brazil nor did it entrust him with any tasks in that country. Despite these denials, the doubts have not entirely subsided.
The criticisms are not limited to this particular name. A report by the CITES Convention has described them as “worrying” the conditions for importing and handling animals in Vantarahighlighting the lack of clear information on the origin of many specimens and the difficulty in verifying that such a large volume of fauna receives adequate care.
NGOs and animal rights activists have called for more information about a complex that, according to estimates in the Indian press, It is home to around 200 elephants, 300 felines and 1.200 reptiles in more than 1.200 hectaresand boasts of having “the best-equipped elephant hospital in the world.” The underlying question is whether all these animals truly come from rescues or if some may have been obtained directly from the wild without sufficient safeguards.
Adding to these suspicions is an agreement signed between the Venezuelan government and Vantara to to move 1.825 live animals to India, revealed by the media outlet Armando.info in March 2025. The magnitude of the operation and the lack of external supervision on the welfare of the specimens have generated uncomfortable comparisons with the possible departure of Colombian hippos to the same destination.
An ethical, political, and environmental dilemma that transcends borders
While these investigations are underway, The proposal to send 80 hippos from Colombia to Vantara is still under evaluation.The Ministry of Environment has formally requested documentation from the Indian center demonstrating its compliance with its country's environmental regulations and the international requirements necessary to authorize the transfer.
Meanwhile, the Colombian government insists that, even if part of the relocation is completed, Euthanasia remains on the table as a management toolThis includes confining some animals to specific enclosures and strengthening reproductive control programs. The idea is to combine measures to prevent the population from exploding.
On the ground, the conflict is experienced very differently depending on who you ask. In Puerto Triunfo and Doradal, many residents fear that The removal of the hippos would be a blow to local tourismone of the few stable sources of income in the region. Others, such as fishermen and farmers, are demanding swift solutions to the increased risks in their daily lives and the damage to the natural environment.
There is no absolute consensus in the scientific community either, although most specialists in invasive species and conservation agree that Maintaining the status quo is not an optionThey argue that allowing the hippopotamus population to continue growing unchecked would make future intervention even more costly and complex, with a greater impact on local biodiversity.
From Europe, the case is being watched closely because of its global warning implications. In a context of intensifying illegal trade in flora and fauna, The story of Escobar's hippos is cited as an extreme example how decisions made outside the law can spiral out of control decades later and force democratic governments to take unpopular measures.
Neither mass culling nor relocation thousands of kilometers offers easy solutions. Between the image of the “narco-hippos” as monstrous invaders and that of innocent animals turned into collateral victims of the war on drugs, Colombia faces an uncomfortable decision that mixes science, ethics, economics, and historical memoryWhat began as a whim of a drug lord has transformed into an uncomfortable mirror reflecting how to manage the long-term damage caused by organized crime and wildlife trafficking on an increasingly interconnected planet.
