Philippines Rice and the Green Revolution
Figure 5. Major Agricultural Activity, 1991
Rice is the most important food crop, a staple food in most
of the country. It is produced extensively in Luzon, the Western
Visayas, Southern Mindanao, and Central Mindanao
(see
fig. 5). In
1989 nearly 9.5 billion tons of palay were produced. In
1990 palay accounted for 27 percent of value added in
agriculture and 3.5 percent of GNP. Per hectare yields have
generally been low in comparison with other Asian countries.
Since the mid-1960s, however, yields have increased substantially
as a result of the cultivation of high-yielding varieties
developed in the mid-1960s at the International Rice Research
Institute located in the Philippines. The proportion of "miracle"
rice in total output rose from zero in 1965-66 to 81 percent in
1981-82. Average productivity increased to 2.3 tons per hectare
(2.8 tons on irrigated farms) by 1983. By the late 1970s, the
country had changed from a net importer to a net exporter of
rice, albeit on a small scale.
This "green revolution" was accompanied by an expanded use of
chemical inputs. Total fertilizer consumption rose from 668 tons
in 1976 to 1,222 tons in 1988, an increase of more than 80
percent. To stimulate productivity, the government also undertook
a major expansion of the nation's irrigation system. The area
under irrigation grew from under 500,000 hectares in the
mid-1960s to 1.5 million hectares in 1988, almost half of the
potentially irrigable land.
In the 1980s, however, rice production encountered problems.
Average annual growth for 1980-85 declined to a mere 0.9 percent,
as contrasted with 4.6 percent for the preceding fifteen years.
Growth of value added in the rice industry also fell in the
1980s. Tropical storms and droughts, the general economic
downturn of the 1980s, and the 1983-85 economic crisis all
contributed to this decline. Crop loans dried up, prices of
agricultural inputs increased, and palay prices declined.
Fertilizer and plant nutrient consumption dropped 15 percent.
Farmers were squeezed by rising debts and declining income.
Hectarage devoted to rice production, level during the latter
half of the 1970s, fell an average of 2.4 percent per annum
during the first half of the 1980s, with the decline primarily in
marginal, nonirrigated farms. As a result, in 1985, the last full
year of the Marcos regime, the country imported 538,000 tons of
rice. The situation improved somewhat in the late 1980s, and
smaller amounts of rice were imported. However, in 1990 the
country experienced a severe drought. Output fell by 1.5 percent,
forcing the importation of an estimated 400,000 tons of rice.
