| Tóm tắt: | Improving agricultural productivity has
been the world’s primary defence against a
Malthusian crisis – the idea that food
demand from a rising population will con-
front limits to natural resources and lead to
famine. In fact, throughout the 20th century
real (inflation-adjusted) agricultural prices
fell (Giovanni, 2005), implying supply was
growing faster than demand, in spite of a
global population increase of 3.7 times
(United Nations, 2004). Hayami and Ruttan
(1971, 1985) showed that the agricultural
success story of the 20th century was
increasingly about raising the productivity
of agricultural resources, rather than expand-
ing the resource base. Figure 1.1 updates a
graphical depiction of long-term trends in
agricultural land and labour productivity
that was popularized in the texts of Hayami
and Ruttan (1971, 1985). The graph shows
the progression in output per worker and
output per area for major global regions dur-
ing the past 50 years. Generally, industrial-
ized nations have defined, and steady
pushed out, the ‘technology frontier’, or the
highest land- and labour-productivity com-
binations. Currently, SE Asia, China and
Latin America are approaching the produc-
tivity levels that today’s industrialized
nations were at in the 1960s. |
