    Author: Abruzzese R.
    Journal: Bull Narc; 1989; 41(1-2):95-8. PubMed ID: 2765723.
    Abstract:
    The estimated areas under coca-bush cultivation in 1988 are expected to total 44,300 hectares in Bolivia, 25,000 hectares in Colombia, 400 hectares in Ecuador and 114,400 hectares in Peru. The estimated projections for 1989 indicate that coca-leaf production may amount to 68,200 tonnes in Bolivia, 20,000 tonnes in Colombia, 300 tonnes in Ecuador and 120,100 tonnes in Peru. Of all the Andean countries, Venezuela is the only one that has no coca-leaf production problem. According to estimates for the period from 1985 to 1989, coca-leaf production will increase by 43.3 per cent in Bolivia, by 13.6 per cent in Colombia and by 26.2 per cent in Peru. Coca-leaf production in Ecuador has consistently followed a downward trend. According to estimates, since 1985 coca-leaf production in Peru has accounted for more than one half of the total amount produced in the Andean subregion, while production in Colombia, though it has increased in the same period, has accounted for a relatively small share. In 1987, estimated coca-leaf production in Bolivia amounted to 30.2 per cent of the total amount produced in the subregion.
