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.
据估计，1988年古柯种植面积在玻利维亚总计44300公顷，在哥伦比亚为25000公顷，在厄瓜多尔为400公顷，在秘鲁为114400公顷。1989年的预计数字显示，古柯叶产量在玻利维亚可能达68200吨，在哥伦比亚为20000吨，在厄瓜多尔为300吨，在秘鲁为120100吨。在所有安第斯国家中，委内瑞拉是唯一不存在古柯叶生产问题的国家。据1985年至1989年期间的估计，古柯叶产量在玻利维亚将增长43.3%，在哥伦比亚增长13.6%，在秘鲁增长26.2%。厄瓜多尔的古柯叶产量一直呈下降趋势。据估计，自1985年以来，秘鲁的古柯叶产量占安第斯次区域总产量的一半以上，而哥伦比亚的产量尽管在同一时期有所增加，但所占份额相对较小。1987年，玻利维亚的古柯叶估计产量占该次区域总产量的30.2%。
