About 25 percent of cultivated land was planted in coconut trees, and it is estimated that between 25 percent and 33 percent of the population was at least partly dependent on coconuts for their livelihood. Historically, the Southern Tagalog and Bicol regions of Luzon and the Eastern Visayas were the centers of coconut production.[5] In the 1980s, Western Mindanao and Southern Mindanao also became important coconut-growing regions.
