Critics of the Colombian eradication program had predicted that it would lead to higher coca production in Peru and Bolivia. However, in November 2003, the US Office of National Drug Control Policy (ONDCP) claimed the area planted with coca in Peru and Bolivia combined fell by 35 km2 in the year up to June, which would suggest that the crop eradication program in neighboring Colombia had not driven production over the borders. According to ONDCP estimates, the area cultivated with coca in Bolivia rose from 244 km2 in 2002 to 284.5 km2 in June 2003, but this increase was more than offset in Peru, where the area fell from 366 km2 to 311.5 km2.
