The Green Revolution: Long Term Consequences?
Norman Borlaug, an
agronomist working in Mexico developed a strain of wheat that was partially
disease resistant, had a higher yield, and was dwarfed so that the crop would
not fall over and be wasted. The winner of a Nobel Peace Prize, Borlaug
launched what is now known as the “Green Revolution,” a period between the
1940s and 1970s filled with the creation of agricultural technology and an
increase in research and development. Crops such as wheat and rice became more
productive as farmers began using more resistant types, known as High Yield
Varieties (HYVs). Irrigation techniques were also developed, enabling more arid
areas to also increase agricultural productivity.
The Green Revolution diffused from
the West to India around the 1960s, starting in Punjab and working its way
across the country. Irrigation, pesticides, technology transfer, introduction
of “semi dwarf high-yielding varieties of wheat and rice, which could yield 2
to 3 times more” than other strains, increase in education, and the creation of
a National Bank for Agriculture and Rural Development (NABARD) all contributed
to India’s revolution (Swaminatham, 2010). When India was plagued by drought and famine,
only about “12 million tons of wheat were produced in the country. By 1968–69,
after the [high yielding varieties] had been introduced, wheat production
jumped to around 16 million tons and by the early 1980s it was double that of
the mid 1960s” (Baker, 2007).
Starting in the wheat growing lands
of Northern India, the Green Revolution slowly worked its way farther south,
spreading different farming technologies and irrigation practices. More often
embraced by large scale farmers who were willing to take risks, use of the HYVs
was able to greatly increase production and thus increased the farmers’ profits.
However, there is now evidence that the Green Revolution may have sparked “a
widening gap between rich and poor, even though the ‘bottom line’ was encouragingly
higher than it used to be” (Baker, 2007). Though this may have been a
byproduct, such income discrepancies exist all over the world and the good
effects, such as averting hunger and famine, are well noted.
Another possibly unexpected result
of Green Revolution technology is contamination of water supply due to the
liberal use of pesticides. Villagers in Uttar Pradesh reported “increases in
formerly unknown ailments such as strokes, heart disease and ‘mystery illnesses,’
particularly of children. These were attributed to the poisoning of water
supplies by overuse of chemical fertilizers, insecticides and pesticides”
(Baker, 2007). For the rural poor, who live in such close contact with the
land, using too many chemicals too close to the living space has proven
detrimental. When harsh chemicals seep into the groundwater or drain into
surface water, villagers have no other source of hydration to rely upon. They neither
have access to filtration systems nor access to tap water and often do not even
know that their water is contaminated.
As mentioned in an earlier blog, our
environment directly affects the minerals and chemicals that we consume. The
presence of fertilizer and pesticide chemicals in the water supply is a serious
matter and cannot easily be remedied. Villagers may also be ingesting residues
of applied chemicals once the crops are harvested, and consumers buying the
exports will also be affected. In time, increased build up of chemicals on and
below the soil could decrease crop yields, thus reversing the original purposes
of the Green Revolution.
Although crop yields, production,
and exports dramatically increased during the Green Revolution, with the new
technology also came new problems. For every issue, one must always examine the
long term effects though the immediate benefits may be dazzling. For example,
creating large scale dam projects are often exciting for those living
downstream who may have future protection from flooding and an increase in
available energy through hydropower. However, what will happen if that dam
breaks in twenty-five, fifty, or even one hundred years? What if the dam has to
be removed because the technology or infrastructure has become outdated? What
then will happen to the river ecosystem or the residents who once felt so well
protected? Every action has a consequence, and when dealing with one’s
environment, the consequence is often far more complex than first imagined. The
Green Revolution saved India from widespread famine in the 1960s, but more
sustainable agricultural practices must now be spread and utilized before
adverse effects begin to outweigh the benefits.
