Cocaleros are the coca leaf growers of Peru and Bolivia. In response to U.S.-funded attempts to eradicate and fumigate coca crops in the Chapare region of Bolivia, cocaleros joined with other grassroots indigenous organizations in the country, such as unionized mine workers and peasants to contest the government. Evo Morales, who became president of Bolivia in 2006, was a leader of the cocalero movement in that country. The coca plant and the War on Drugs Coca has been cultivated for 8,000 years by indigenous people in the Andes for medicinal and religious reasons. As a stimulant, it is helpful in overcoming altitude sickness in the high Andes, and can be chewed and made into tea. Other medicinal uses include pain relief, staunching blood flow, combating malaria, ulcers, asthma and improving digestion. It is also configured in many religious ceremonies as offerings to Apus, Inti, and the Pachamama and as a method of divination. It was introduced to Europe in the 16th century, but it was not until the mid-19th century that it began to be refined into cocaine. Its cultivation was prohibited by Bolivian law, except in the region of Yungas despite its affinity to the climate and land of the Chapare region. Coca crops in Chapare were thus targeted for eradication. Because coca and cocaine were being trafficked up through South and Central America to the United States, coca production in South America came to the attention of the U.S. Drug Enforcement Administration, which, subsequently under Plan Colombia, began to fund eradication efforts across the continent. Plan Colombia sent hundreds of millions of dollars in military aid, training and equipment to Central and South American countries, thereby militarizing the region and local and national governments' responses to coca production. Cocaleros who make their livings growing and selling coca were the most negatively affected by the policies, as their crops were burned, ripped up, or sprayed with herbicide. Coca producers are left with few alternatives for subsistence, and therefore call for the legalization of coca. Also the anti-drug militancy has targeted left wing guerrilla groups like the Revolutionary Armed Forces of Colombia and gangs who are involved in the drug trade. In 1987, UMOPAR, La Unidad Móvil Policial para Áreas Rurales, was formed as an anti-narcotic counterinsurgency force in Bolivia. It received training and monetary aid from the American Drug Enforcement Administration and led raids on coca fields and suppressed
