| Tóm tắt: | The term ‘green revolution’ was coined in the 1960s after improved varieties
of wheat dramatically increased yields in test plots in northwest Mexico. The
green revolution, attributed to Norman Borlaug, an American scientist, ush-
ered in an era of agricultural surpluses in many areas of the world. The subsist-
ence agriculture practised in many regions was replaced by intensive agriculture,
which required farm mechanization and increased inputs in the form of labour,
high-yielding varieties, chemical fertilizers and pesticides. Many countries that
had imported food grains before the green revolution became exporters of
these commodities. The green revolution forever changed the way agriculture
was conducted worldwide, benefiting the people of many countries in need of
increased food production.
However, the failure of the green revolution in several areas and the nega-
tive impacts associated with it have forced mankind to look for alternatives.
The accelerated inputs have resulted in intolerable pressure on fragile agroeco-
systems. The situation is compounded by a shrinking portfolio of species and
an emphasis on a handful of major crops that have narrowed the number of
species on which global food security depends. The consequences of crop fail-
ures from unforeseen stresses, pests and diseases are potentially catastrophic.
Therefore, there is an urgent need to broaden the species portfolio for agricul-
ture and food security. The need of today is a gradual shift from input-intensive
to environmentally sound sustainable agriculture. This requires a shift in focus
towards increasing production by using agriculturally marginal lands.
Underutilized crops can be the answer to this burning problem. |
