The food issue
What causes the food issues?
Lack of food security- 1 billion undernourished people across the world yet
we waste one quarter of food in Western Europe and North America.
Uneven distribution of food- one quarter of grain is produced in LEDC's yet
they have half the world's population.
intensification of food production- has led to environmental issues
rising food miles- can raise prices
health issues from over nutrition
Growing food production- Western Europe and north America improvements in
Intensive farming in the UK
Large inputs to gain has high output as possible from the land
use of organic and inorganic fertilizers
improved water technology (drainage)
mechanisation (number of workers reduced from 2million 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
Environmental consequences
Unsuitable land cultivated-e.g. chalk down lands led to soil erosion, rill and
gulleying which are unsightly.
Impact on wildlife- loss of habitat, increased use of pesticides leading to
loss of biodiversity.
Inefficient irrigation
Loss of biodiversity
Economic and social consequences
Distorted high prices
Rich get richer and the poor get poorer
70% of total EU budget
Aesthetic pleasure of countryside destroyed
Unemployment in the countryside (number of workers decreased)
Green revolution in developing countries

Population and resources
The green revolution was successful agricultural projects in developing countries.
It was particularly effective in India. It involved:
Expansion of existing farming areas
Double cropping existing farmland to maximise yields
High yield variety seeds
Indian farmers were quick to adopt the new varieties:
In 1960 1.9million 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 1.9 million tonnes in
1965 to 5.…read more
