Working with limited aid of the U.S. Agency for International Development (USAID), the Peruvian Government carries out alternative development programs in the leading coca-growing areas in an effort to convince coca farmers not to grow that crop. Although the government previously eradicated only coca seed beds, in 1998 and 1999 it began to eradicate mature coca being grown in national parks and elsewhere in the main coca growing valleys. In 1999 the government eradicated more than 150 km2 of coca; this figure declined to 65 km2 in 2000, due largely to political instability. The government agency "Contradrogas", founded in 1996, facilitates coordination among Peruvian Government agencies working on counter-narcotics issues. Alternative crops, however, are not economically comparable to coca. 2004 prices indicate an annual income per hectare of $600 for coffee and $1000 for cocoa, versus up to $7500 for a hectare of coca.
