The Green Revolution


            Hey, everyone! This is Yann, one of the team members. I’m really interested in talking about GMOs, so I wrote about them today.
For millenniums, farming was simple; soil was tilled, seeds were planted, and crops were irrigated before being harvested. No great global initiative was taken to avoid great agricultural crises, for there weren’t very many, until the Great Bengal Famine of 1943. Around 4000 square miles of agricultural land was damaged and reserve stocks were destroyed. It is estimated that between 1.5 and 4 million out of 60.3 people died of starvation, malnutrition and disease.

A calamity of this level got scientists and politicians thinking. What if there was a way to make crops more resistant to catastrophes? How could we improve the yield of crops? Some agronomists developed cereal grain varieties that were semi-dwarf, high-yield, and disease-resistant. In 1961, this system was implemented region of Punjab (situated in Northern India). Instantaneous success in the program brought forward new clients like Mexico, Pakistan, and the Philippines. Soon enough, the “Green Revolution” was in full swing.

The successes of the Green Revolution were remarkable. By 1970, India and Pakistan’s wheat production had nearly doubled. Wheat efficiency got remarkably better; in 1964, India produced 12 million tons of wheat on 14 million hectares of land. 30 years later, that number had risen to 57 million tons on only 24 million hectares of land. Many countries that underwent a green revolution became self-sustainable and economies were boosted. The Green Revolution is credited to have saved the lives of up to a billion people, with figures like hunger and malnutrition dropping significantly thanks to its success.

Although the Green Revolution was very successful in many regards, many issues have immerged that once again challenge global agriculture. Corporations like Monsanto have now taken control of the seed market/production, forcing farmers to continually buy new seeds annually in order to continue farming. The problem is that it is extremely expensive for the farmers, with 100 grams of genetically modified seed costing £10, compared with less than £10 for 1,000 times more traditional seeds. In addition to the cost of the seeds, farmers need to purchase stronger pumps in order to irrigate their high-yield crops (which need quite a lot more water than normal crops). In order to pay these debts, many farmers are forced to get loans from high-interest unofficial lenders that charge as much as 24% interest.

There are also environmental impacts due to genetically modified crops, for instance, the high amount of chemical fertilizers has led to 6% of all agricultural land being rendered anemic. Also, due to the increased amount of irrigation needed to sustain the high-yield crops, the aquifers of northern India fell by about four inches per year from 2002 through 2008 - representing about the same total volume of water as melted from Alaska's glaciers over the same period. Genetically modified farming has progressively become a less sustainable practice; a great ecological issue that will have to be dealt with in the future.

Genetically modified crops have radically changed the global landscape in numerous ways, from how we get our food to how much we get. Although the Green Revolution has been key to our growth as a planet, it raises many issues for the next generations to come. Whether we continue to follow this path of genetically modified foods or redirect our focus to other systems, the Green Revolution has made us realize that there’s more to food and agriculture than we think.
