In the small town of Doradal, nestled in the lush heart of Colombia, the afternoon air is often punctuated by a sound that belongs thousands of miles away in the African savannah: the deep, resonant grunt of a hippopotamus. For the locals, these massive mammals are more than just a curiosity; they are a living legacy of the country’s most turbulent era and a burgeoning pillar of the local economy.
The animals are the descendants of four hippos brought illegally to Colombia in the 1980s by Pablo Escobar for his private zoo. After the government seized Escobar’s estate following his death, the hippos were left behind. Without natural predators to keep them in check, the population exploded, transforming a narco-eccentricity into one of the most complex invasive species crises in South America.
Now, the Colombian government finds itself at a crossroads. With a population estimated at 200 animals that could double within five years, officials are weighing a grim necessity—culling—against a lavish, albeit logistically daunting, lifeline offered by one of the world’s wealthiest men.
An Ecological Imbalance in the Magdalena River Valley
While the image of hippos floating in Colombian lakes may seem whimsical to tourists, biologists warn that the reality is an environmental disaster in sluggish motion. The hippos have effectively rewritten the chemistry of the local waterways.
Nataly Castelblanco, a biologist specializing in the region, explains that the sheer volume of waste deposited by the hippos into lakes and riverbeds is altering the water’s pH levels and depleting oxygen. This “transversal impact” creates a lethal environment for native aquatic plants, which in turn collapses the food chain for indigenous fish and other wildlife. As the underwater flora dies off, the entire ecosystem loses its stability, threatening the biodiversity of the region.
Colombia initially attempted to manage the growth through more humane means. The government funded sterilization programs, utilizing both surgical procedures and contraceptive injections. However, these efforts proved unsustainable. The costs were prohibitive, and the physical risk to the animals and the veterinary teams during the capture and procedure process made large-scale sterilization an impractical solution for a wild, aggressive population.
The Divide Between Science and Sentiment
The push for culling—the selective killing of the animals to manage population density—has met fierce resistance in Doradal. For the people of the town, the hippos have transitioned from symbols of a drug lord’s excess to symbols of community identity and economic survival.
From hippo-themed statues lining the streets to the sale of T-shirts and keyrings, the “cocaine hippos” have created a niche tourism industry. Local business owners, such as Tania Galindo, argue that the animals are now an integral part of the community. “There’s no other place outside of Africa with wild hippos,” Galindo noted, advocating for population control that respects the lives of the animals.
This tension creates a difficult political landscape for the Colombian environment ministry. While the scientific consensus points toward culling as the most effective tool—similar to the management of lionfish in the Atlantic or camels in Australia—the emotional and economic ties of the local population make such a move politically volatile.
The Ambani Lifeline: A Billionaire’s Proposal
Into this deadlock stepped Anant Ambani, the Indian billionaire and son of Mukesh Ambani, who has offered to relocate 80 of the hippos to his wildlife reserve in Gujarat state. The offer provides a potential “third way” that avoids culling while addressing the population crisis.
However, the proposal has been met with significant skepticism from the academic community. Sergio Estrada, a biology professor at Bogota’s Rosario University, highlights the staggering logistical hurdles involved in moving semi-aquatic giants across continents.
The journey would begin with a perilous 150-kilometer transport by truck from the capture sites to the Rio Negro airport near Medellin. From there, the animals would face a grueling long-haul flight to India, necessitating specialized aircraft, stopovers, and constant sedation to ensure the animals remain safe and relaxed.
Beyond the transport, there is the question of habitat. Critics argue that the reserve in Gujarat may be too small to accommodate wild animals that have grown accustomed to the vast, unfenced rivers of Colombia. There is a legitimate concern that relocating the animals would simply move the problem from one geography to another, trading an ecological crisis in Colombia for a confinement crisis in India.
Management Options Comparison
| Method | Primary Advantage | Primary Drawback | Feasibility |
|---|---|---|---|
| Culling | Immediate population reduction | High public and local opposition | High (Technical) |
| Sterilization | Humane and permanent | Prohibitively expensive/risky | Low (Scalability) |
| Relocation | Saves animals; avoids culling | Extreme logistical complexity | Moderate (Financial) |
The Ticking Clock
The urgency of the situation cannot be overstated. The Colombian environment ministry has warned that without drastic intervention, the population could double in the next five years. This growth would not only accelerate the degradation of the water systems but could increase dangerous encounters between the aggressive mammals and the local human population.

The government’s mid-April announcement to cull up to 80 animals this year remains the baseline plan, but the Ambani offer has introduced a variable that could delay or replace that action. The decision now rests on whether the Colombian state views the logistical risks of a transcontinental move as more acceptable than the local backlash of a cull.
The next critical checkpoint will be the official response from the Colombian environment ministry regarding the technical viability of the Gujarat relocation plan and the finalization of the 2026 population control budget.
