The food issues and solutions
Causes of the food issue
Lack of food security- 1 billion undernourished across the world
Uneven distribution of food- ¼ of grain is produced in LEDC's yet they have
half of the world's population
Intensification of food production- led to environmental issues
Rising food miles- increase prices
Health issues from over nutrition
Growing food production with improvements in agriculture- intensive farming in
the UK
Aim of large inputs to gain as high output as possible from land
Use of inorganic/organic fertilizers
Improved water technology (drainage/irrigation)
Mechanisation of farming (number of workers has reduced from 2 million in
1800 to 250,000 due to people being replaced by machines)
Remove hedgerows- create more land that can be used to maximise profits
Clear away climax vegetation for agricultural use
Farm amalgamation- farms merge to become bigger
- Unsuitable land cultivated e.g. chalk down lands led to soil erosion
- Impact on wildlife- loss of habitat, increased use of pesticides
leading to loss of biodiversity
- Inefficient irrigation
- Loss of biodiversity
Economic and social:
- Distorted high prices
- Rich get richer, poor get poorer
- 70% of total EU budget
- Aesthetic pleasure of countryside destroyed
- Unemployment in rural areas (number of works reduced)
Green revolution in developing countries
The green revolution was successful agricultural projects in developing countries
such as India. It involved:
Expansion of existing farm areas
Double cropping existing farmland to maximise yields

High yield variety seeds
Indian farmers were quick to adopt the new varieties.
In 1960, 1.9 million hectares were sown with the new high yield crop. By
1980, this had increased to 43 million hectares.
In the Punjab district, wheat production increased from 1.9million tonnes in
1965 to 5.16 million in 1972
By the late 1970's India could export grain abroad, so it was more than self
efficient.…read more
