Future Implications
Green Revolution and the Environment
-There are assumptions that a Green Revolution could be possible for African agriculture
-The green revolution came to a stop in the late 1960's in India
-Rapidly growing population and limited availability of land= more famines
The Message of the Political Cartoon
-The green revolution was able to introduce high-yield crop varieties and applications of modern agricultural techniques, which led to an increase in food production
-A new farming system, 'Organic Green Revolution', could be used as an intensified farming system
- The Green Revolution created many new technologies that caused many environmental problems
- Environmental concerns have been raised because of the high usage of agrochemical-based pest and weed control in crops. This has lead to concerns for the health of the environment and humans.
- Through the use heavy usage of fertilizers, pesticides and irrigation, waterways were polluted, beneficial insects and wildlife were killed, and there has been a buildup of salt on farmlands.
- The Green Revolution also caused food insecurity; in 2009 the amount of undernourished people surpassed 1 billion people. This was caused by a dramatic increase in food prices.
-Developing countries found it difficult to move closer to food security targets. The number of undernourished people increased from 1990-1992 and in 2010
- In the span of three decades the Green Revolution increased the productivity of things such as major cereals, rice, wheat and maise.
-The amount of rice and wheat doubled; this was made possible by incorporating scientific advances in plant breeding with technology that allows the yield potential of crops to be realized
-These scientific advances also allowed for crops to be grown under conditions similar to that of a farmer in a developed country that is growing crops
-This helped to increase access to affordable nutritious food in India, Mexico, Asia, Pakistan and the Philippines.
-The Green Revolution strives to modify the environment to create optimal conditions for crops and livestock to grow; helping with food security.
- This political cartoon shows the benefits of the Green Revolution.
- It depicts a farmer giving “the world” to a child in a developing and starving country.
- The farmer is doing this by offering the child crops, such as wheat and rice.
- The Green Revolution increased crop production, which meant more food for developing countries. This cartoon shows an example of how the Green Revolution helped to increase food security globally.
-This system would be based on the use of manure produced by improved dairy cows (cross breeds of European and local cattle), which would then be deposited on the crops
-Also, the new agricultural technology has created more amounts of employment opportunities in the agricultural sector.
Kahoot Quiz!
Dr. Norman Borlaug
-This would be suitable, because it does not depend on irrigation systems and chemicals
-He proposed the high yielding of crops, with the help of chemical fertilizers and irrigation, which increased production needed to make India self-sufficient in food grains
