Coca eradication is a strategy promoted by local authorities in coca-producing countries, often with support from foreign partners such as the United States and the European Union, to eliminate the cultivation of coca—a plant whose leaves are not only traditionally used by indigenous cultures but also, in modern society, in the manufacture of cocaine. This approach, which gained momentum starting in 1961 as part of the United States-led "war on drugs," was adopted in place of running educational campaigns against drug usage.
The strategy was adopted in place of running educational campaigns against drug usage. The prohibitionist strategy is being pursued in the coca-growing regions of Colombia (Plan Colombia), Peru, and formerly Bolivia, where it is highly controversial because of its environmental, health and socioeconomic impact. Furthermore, indigenous cultures living in the Altiplano, such as the Aymara people, use the coca leaf (which they dub the "millenary leaf") in many of their cultural traditions, notably for its medicinal qualities in alleviating the feeling of hunger, fatigue and headaches symptomatic of altitude sicknesses. The growers of coca are named and part of the coca production for traditional use is legal in Peru, Bolivia and Chile.
Aerial spraying of glyphosate herbicide, one of the most controversial methods of coca eradication, has taken place in Colombia exclusively because of that government's willingness to cooperate with the United States in the militarized eradication of coca after signing Plan Colombia in 2000. In many cases the spraying is carried out by American contractors, such as DynCorp, using planes and helicopters to spray glyphosate on coca plantations. Aerial spraying has been repeatedly condemned by human rights and environmental activists because of its effect on human populations and local soil and water systems. In December 2000, Dutch journalist Marjon van Royen found that "because the chemical is sprayed in Colombia from planes on inhabited areas, there have been consistent health complaints in. Burning eyes, dizziness and respiratory problems being most frequently reported." In some areas, 80 percent of the children of the indigenous community fell sick with skin rashes, fever, diarrhoea and eye infections. Driven Mad by Itch, NRC Handelsblad, December 28, 2000 Because the glyphosate is sprayed from the air, there is a much higher chance of human error when spraying suspected illegal coca plantations. In many cases the wrong fields are sprayed, resulting in not only a total loss of the farmer's crop- but the loss of that field altogether as nothing will grow where the herbicide has been sprayed.Hugh O’Shaughnessy and Sue Branford, Chemical Warfare in Colombia: The Costs of Coca Fumigation (London: Latin America Bureau, 2005.) Though official documentation of the health effects of glyphosate spraying in Colombia are virtually non-existent, neighbouring Ecuador has conducted studies to determine the cause of mysterious illnesses amongst people living along the border of Colombia and has since demanded that no aerial sprayings occur within 10 km of the border because of the damages caused to the people, animals and environment in that area. In 2015, Colombia announced a ban on using glyphosate in these programs due to concerns about human toxicity of the chemical.BBC. May 10, 2015. Colombia to ban coca spraying herbicide glyphosate
In addition, the U.S. has also been involved in the development of the fungus Fusarium oxysporum to wipe out coca. Vicious Circle: The Chemical and Biological 'War on Drugs' report by the Transnational Institute (TNI), March 2001 The Re-emergence of the Biological War on Drugs, TNI Drug Policy Briefing 7, May 2004 In 2000, the Congress of the United States approved use of Fusarium as a biological control agent to kill coca crops in Colombia (and another fungus to kill opium in Afghanistan), but these plans were canceled by then-President Bill Clinton, who was concerned that the unilateral use of a biological agent would be perceived by the rest of the world as biological warfare. The Andean nations have since banned its use throughout the region. (The use of biological agents to kill crops may be illegal under the Biological Weapons Convention of 1975.)
On June 25, 2003, the Superior Administrative Court of the Colombian department of Cundinamarca ordered a stop to the spraying of glyphosate herbicides until the government complies with the environmental management plan for the eradication program. It also mandated a series of studies to protect public health and the environment. Colombia Court Nixes Spray Program , Colombia Update The Colombian State Council, the country's maximum administrative authority, later overruled the court's decision to stop fumigations.
Recently, Boliviana negra, a glyphosate-resistant type of coca plant has been found.
With the growth of the Colombian in the 1980s, coca leaf became a valuable agricultural commodity, particularly in Peru and Bolivia, where the quality of coca is higher than in Colombia. To supply the foreign markets, the cartels expanded the cultivation to areas where coca was not a traditional crop. Many poor Peasant, driven from the central highlands by lack of land or loss of jobs, migrated to the lowlands and valleys of the eastern Andes, where they turned to the cultivation of coca.
To counter this development, the U.S. government, through its foreign aid agency USAID, has promoted a policy of crop substitution, whereby coca cultivation is replaced by coffee, banana, pineapple, palm heart, and other crops suitable for a tropical climate. However; many remote coca-growing areas lack the infrastructure to get such perishable products to market on time. Coca on the other hand stores well and is easily transportable. The price of coca has remained high and in many cases remains a more attractive crop to farmers than these alternatives.
Despite these obstacles, many farmers have embraced alternative crops. In 2006, Bolivia, as a result of alternative development programs, exported US$28 million of banana, US$1.9 million of pineapple, and US$7.0 million of palm heart.Bolivian Chamber of Exporters - CAMEX These industries now employ more than 20,000 people in the Chapare region.
of the Single Convention on Narcotic Drugs, a treaty promulgated with U.S. backing in 1961, states that "The Parties shall so far as possible enforce the uprooting of all coca bushes which grow wild. They shall destroy the coca bushes if illegally cultivated."
The US-based Drug Enforcement Administration, along with local governments, has frequently clashed with cocaleros in attempts to eradicate coca across the Andes. This map shows the Chapare Province region in Bolivia, which has historically been heavily targeted for coca eradication. Human rights such as Human Rights Watch have accused the US of human rights abuses in the "coca war".

Meanwhile, the US-based Stepan Company is authorized by the Federal Government to import and process the coca plantMay, Clifford D. "How Coca-Cola Obtains Its Coca", The New York Times, July 1, 1998. Accessed December 4, 2007 which it obtains mainly from Peru and, to a lesser extent, Bolivia. Besides producing the coca flavoring agent for Coca-Cola, Stepan Company extracts cocaine from the coca leaves, which it sells to Mallinckrodt, a St. Louis, Missouri pharmaceutical manufacturer that is the only company in the United States licensed to purify cocaine for medicinal use.
The U.S. figures were very different from preliminary estimates in September 2003 by the head of the UN Office on Drugs and Crime in Colombia, which indicated that output in Peru and Bolivia may have risen by as much 21%, or 150 km2 that year. The White House office said its estimate was based on sampling from high resolution satellite imagery. The United Nations used a different technique and had not yet put out any formal estimate for 2003.
A March 2005 report by the ONDCP indicated that despite record aerial spraying of over 1,300 km2 of coca in Colombia in 2004, the total area under coca cultivation remained "statistically unchanged" at 1,140 km2. In response to the report, the Washington Office on Latin America (WOLA), an NGO that monitors the impact of US foreign policy in Latin America, observed that the aerial spraying strategy appeared to have hit its limits. According to WOLA, the new ONDCP data suggested a continued "balloon effect" as aggressive spraying in some areas has not deterred new cultivation elsewhere. The WOLA Senior Associate for Drug Policy commented, "The stable cultivation in 2004 throws into doubt US officials’ predictions of a major impact on US drug prices and purity." Regardless, Colombian President Álvaro Uribe vowed to press ahead with the U.S.-financed fumigation of coca crops. Aerial Spraying Fails to Reduce Coca Cultivation in Colombia , WOLA, March 31, 2003
Official estimates of coca cultivation in Peru for 2005 have yet to be released, but the State Department's own reporting suggests that cultivation in Peru has increased.
In Bolivia, there has been a decrease in clashes since 2004, when Evo Morales and former President Carlos Mesa struck a deal allowing the Chapare region to legally grow a limited amount of coca, in addition to the already legal Yungas region.
In 2006 the Colombian government destroyed around 730 square kilometres, reaching new records in coca plant destruction. The Colombian government planned to destroy around 500 km2 of coca plants in 2007, which would leave only around 200 km2 left. The Colombian government planned to destroy the remaining coca gradually over the following years.
