When did the Green Revoloution take place?
1940's
1 of 21
What did the green Revoloution do?
It spread the use of intensive farming methods to increase food production across the world
2 of 21
How did the green Revoloution increase food production?
Used higher yielding crops, used monoculture so (one crop over big area). Used irrigation technologies (electric sprinklers). Used agrochemicals (fertilisers and pesticides). Used mehchanisation (machines for farming)
3 of 21
How did the green revolution negatively impact small farms?
They couldn't afford the technology so we're made bankrupt, leading to rural unemployment and food shortages
4 of 21
What's are the negative impact of using monoculture?
It reduces biodiversity and one single pest or disease can wipe out all the crops and this lowes food supply
5 of 21
How does Irrigation damage the environment?
It can lead to water logging of the soil
6 of 21
How does the use of Agrochemicals damage the environment?
They can cause pollution (eg in the water eutrophication)
7 of 21
What are a Genetically Modified Crops?
Crops genetically altered to have genes which give them beneficial characteristics
8 of 21
What characteristics might the GM crops be given?
Pesticide intolerant, high yielding (eg make them bigger), long lasting
9 of 21
What concerns are there regarding GM crops?
Farmer may feel it's acceptable to use agrochemicals because it won't damage the environment. They may harm non pest such as butterflies.

Disadvantages of land colonisation
Can often involve deforestation or conflicts with indigenous people
11 of 21
Disadvantages of land reform
It may include conflicts over who's entitled to the land
12 of 21
What is commercialisation
It's the change from subsidence farming to commercial farming
13 of 21
How does commercialsation increase food production
It used capitalist intensive green revolution strategies
14 of 21
Give an example of commercialisation
In Kenya, many fresh vegetables are grown for export only to meet changes of demand
15 of 21
Disadvantages of commercialsation?
It reduces food security for the producers because their food is for exports only
16 of 21
What's appropriate technology?
The use of small scale subsidence farming to increase food security for local people. Uses local materials, skills of the local people and it's appropriate to the local climate and technology
17 of 21
What's an example of appropriate technology
Donkey Plough- Sudan
18 of 21
What does The Donkey Plough Charity in Sudan do?
A lightweight harness and plough is made for a donkey out of local materials such as straw and cotton. All families have a donkey which means that the poorer families can still grow crops to feed their families which increased food security

How do Diguettes in Burkino Faso increase food production and security
They are lines of stone which are put along the contours of gently sloping farmland. Allows the ground to slowly soak up the rainwater and stops soil erosion by it being blown away.
20 of 21
How does Drip Irrigation in Kenya and India increase food production?
It saves water and fertiliser by allowing it to drip in the soil slowly. This makes the amount of fertiliser or water used more sustainable.
