CHANGES IN FOOD PRODUCTION
THE GREEN REVOLUTION
• Launched by the FAO in the 1960’s to combat famine and malnutrition in the Developing world.
• To take advantage of new developments in food technology.
Development of a new variety of crops
Hybridization
Cross-breeding of seeds & plants
Development of the Miracle Rice
• The IR varieties improved the growth, disease resistance, and yield increase of rice.
The Green Revolution led to Water control projects
• Dams and new wells were built.
Many dams were built in LEDC’s
The Green Revolution led to the development of better fertilizers
Green Revolution led to an increase in the use of fertilizers and
pesticides
This has been a major criticism of the Green Revolution
• Creates LEDC dependency on First World agricultural manufacturers
The Green Revolution led to a better storage of food
• Need to build more storage bins
Green Revolution led to more mechanization and better farming
methods• Multiple cropping – a
new crop is sown as soon as harvest is over
• Intercropping – a new crop is sown after the first crop has matured but before it is harvested.
• This makes weed control easier and reduces pest attacks.
The Green Revolution led to the call for more land reform.
• A controversial and political issue for many developing countries.
• Some were more successful than others.
• Major successes occurred in the development of agricultural cooperatives
PROMOTION OF INTERMEDIATE TECHNOLOGY
• BAMBOO TUBEWELL
• BICYCLE OPERATED MACHINES
IRRIGATION
• To improve water supply for areas with seasonal precipitation patterns.
LAND RECLAMATION
• To increase land acreage for farming.
INTENSIFICATION OF PLANT WEEDING
• To improve overall yields
INCREASED USE OF PEST CONTROL
DEVELOPMENT OF NEW MARKETING TECHNIQUES
TRANSPORT IMPROVEMENTS WERE IMPLEMENTED
THE RESULTS
• Enormous increase in food supply in most LEDC’s; sub-Saharan Africa was the main exception
• Socially more developing farmers lost their independence
• Certain cultural groups had to change to sedentary farming; eg. The Masai in Kenya
• More LEDC dependence for fertilizers, pesticides, technology
• Ecological changes• 1. pollution of water & soil• 2. more soil erosion• 3. deforestation• 4. simplication of biomes• 5. loss of individual species
