Résumé

TLDRThe Green Revolution, initiated by Norman Borlaug, was a pivotal movement in the 20th century that dramatically increased agricultural productivity, particularly in developing countries. Borlaug's innovations in wheat cultivation, such as rust-resistant varieties and shuttle breeding, were instrumental in transforming farming practices in Mexico and later in South Asia, especially India and Pakistan. By the 1970s, many countries experienced significant increases in cereal production, alleviating fears of mass starvation. The revolution led to remarkable yield increases, particularly in wheat, and has had a lasting impact on global food security.

Chronologie

  • 00:00:00 - 00:03:54

    The Green Revolution, a pivotal event of the 20th century, significantly increased agricultural productivity, preventing millions from starvation. It began with Norman Borlaug, an American scientist who, in the mid-1940s, worked in Mexico to enhance crop yields through innovations like rust-resistant wheat and shuttle breeding programs. Borlaug actively engaged with local farmers, sharing his knowledge and techniques. His efforts contributed to a surge in agricultural productivity in the U.S. post-World War II, which he adapted for developing countries. By the 1960s, the Green Revolution spread to South Asia, particularly India and Pakistan, where local farmers embraced these advancements. By 1970, many countries experienced substantial increases in cereal production, and Borlaug later promoted hybrid rice in China. The Green Revolution defied predictions of mass starvation in the developing world, leading to unprecedented food production and yield increases, particularly in wheat. This legacy continues to influence agricultural practices globally.

  • 00:00:01
    The Green Revolution is one of the most important events of the 20th century
  • 00:00:05
    and it has led to many millions of people being fed
  • 00:00:08
    when they otherwise would have starved or gone hungry.
  • 00:00:13
    A green revolution refers most generally to
  • 00:00:15
    an increase in the productivity of agriculture.
  • 00:00:17
    But our green revolution starts with Norman Borlaug,
  • 00:00:21
    an American who eventually won a Nobel Peace Prize.
  • 00:00:24
    Borlaug was an American scientist and in the mid 1940s
  • 00:00:27
    he found himself working in central Mexico
  • 00:00:30
    as part of a Rockefeller Foundation program to improve crop yields.
  • 00:00:34
    He came up with some major breakthroughs, including rust-resistant wheat crops,
  • 00:00:39
    shuttle breeding programs to accelerate crop engineering
  • 00:00:42
    and stronger and higher yielding wheat plants.
  • 00:00:45
    Rather than just keeping this knowledge to himself,
  • 00:00:48
    Borlaug tried to spread it to his many Mexican farmers as possible.
  • 00:00:52
    And among the Mexican farmers, he was known for his willingness
  • 00:00:55
    to get his hands dirty
  • 00:00:56
    and just go over there out in the fields and work with them.
  • 00:01:00
    Basically, these ideas worked.
  • 00:01:02
    Borlaug is best thought of as a kind of
  • 00:01:04
    genius offshoot innovator from a more general increase of
  • 00:01:07
    agricultural productivity in the United States.
  • 00:01:11
    For instance, between 1880 and 1940,
  • 00:01:13
    agricultural productivity in the United States
  • 00:01:16
    was going up by about 1 percent a year.
  • 00:01:19
    That's OK, but after World War II,
  • 00:01:21
    the trend rate of growth went up to about 2.8 percent a year.
  • 00:01:25
    So this was a time when American agriculture itself was flourishing.
  • 00:01:29
    This was due to more and better fertilizer,
  • 00:01:31
    greater and better use of mechanized vehicles,
  • 00:01:34
    better crops and hybrids, larger farms,
  • 00:01:37
    and in general the application of large-scale business
  • 00:01:40
    and business management to growing food.
  • 00:01:44
    Borlaug took some of these ideas, improved them
  • 00:01:46
    and adapted them for use to developing countries.
  • 00:01:51
    In the early 1960s, the green revolution started to spread to South Asia,
  • 00:01:55
    most notably India and Pakistan.
  • 00:01:57
    And this was due in large part to the personal efforts of Norman Borlaug.
  • 00:02:02
    During 1969 to 1970,
  • 00:02:04
    55% of the wheat hectares sown in Pakistan used Mexican
  • 00:02:09
    or Mexican derived varieties of wheat.
  • 00:02:11
    In India it was 35% of wheat hectares sown.
  • 00:02:16
    Domestic farmers in India and Pakistan were big advocates of this green revolution
  • 00:02:20
    and they did the rest of the work
  • 00:02:22
    and their political leaders allowed this change to happen.
  • 00:02:25
    By 1970, the countries with significant increases in cereal production
  • 00:02:29
    due to the green revolution were
  • 00:02:31
    Afghanistan, Sri Lanka, then called Ceylon,
  • 00:02:35
    Indonesia, Iran, Kenya, Morocco, Malaysia, Thailand, Tunisia and Turkey.
  • 00:02:40
    Later in the 1970s, Borlaug encouraged the Chinese
  • 00:02:44
    to move to a more productive variety of hybrid rice.
  • 00:02:48
    Before the green revolution, it was a common prediction
  • 00:02:51
    that the developing world was facing a future of mass starvation.
  • 00:02:55
    In large part this green revolution was not foreseen by commentators.
  • 00:02:59
    Now, it's the case that the world is feeding many more people than ever before.
  • 00:03:04
    Yield rates on various crops rose dramatically.
  • 00:03:07
    They rose for grains, they rose for cereals, they rose for a rice
  • 00:03:11
    and they rose most of all for wheat by nearly a factor of fourfold.
  • 00:03:15
    That's a comparison 1950 to 1998 for India kilograms per hectare.
  • 00:03:23
    The green revolution has been extremely impressive
  • 00:03:25
    and of course much of the developing world picked up where Norman Borlaug left off.
