Recently in my World Food Problems course, we discussed the
Green Revolution. Since I have never heard of the Green Revolution before that
class, I figured that some of you might not know about it either. This is what
has led me to share this topic with you.
During the late 1950s to mid-1960s a concerted research
effort was established to create modern or high-yielding crop varieties,
beginning with rice and wheat plants in Asia and Latin America. This research
effort later became titled as “The Green Revolution.”
Early modified crop varieties of wheat and rice were quickly
adopted in areas with either good irrigation systems or reliable rainfall.
However, adoption was much slower in sub-Saharan Africa where irrigation is
limited and rainfall is unreliable. Additionally, in these areas crop variety
is limited as well, increasing the difficulty for researchers to find suitable
genetic alternatives.
In the early days of the Green Revolution only 2 centers
were established for modern variety crop research, however currently 16 centers
have been established for research purposes. These centers support 8500
scientists/staff and have an annual budget of $350 million.
Researchers, Evenson & Gollin, recently assess the
impact of the Green Revolution and how the food market would have differed
without this research. Evenson & Gollin report that the late Green
Revolution period (1981 to 2000) has the most gains. Yield growth from modern
varieties accounted for almost all of the increases in food production in
developing countries. Additionally, researchers were able to model outcomes if
the Green Revolution did not take place. Without international research in
crops…
- Calorie intake per capita would be 13.3-14.4% lower in the developing world
- There would be a 6.1-7.9% increase in malnourished children in developing countries
- Developed countries would have to increase food imports by 27-30%
While criticism exist about the sustainability of intensive
cultivation, soil degradation, chemical pollution, aquifer depletion and soil
salinity. Evenson & Gollin highlight the fact that developing countries
don’t have many alternatives to meet population needs with low environmental
impact. Further research needs to be completed on environmentally friendly technologies
that developing countries can assess and adopt.
Even though criticism still exits, the Green Revolution
lowered food prices worldwide. During
this period of concerted research effort productive increased and prices fell.
The Green Revolution exhibits what can be accomplished when the brightest in
the world come together to solve a problem. With researchers working together
to address diseases and challenges from developing countries, anything can be
accomplished.
