Strategies to increase food supply
Lesson details
Learning outcome
I can describe different strategies used to increase food supply and outline the advantages and disadvantages of Kenya's Mwea irrigation scheme.
Key learning points
- Different strategies can be used to increase food supply.
- Strategies to increase food supplies include irrigation, aeroponics and hydroponics.
- Biotechnology has a role, for example, producing genetically-modified crops that are drought-resistant.
- A new green revolution is needed to increase the production of smaller farms without harming the environment.
- Mwea Irrigation Scheme, Kenya, is a large-scale agricultural development with advantages and disadvantages.
Keywords
Hydroponics - growing plants using mineral nutrient solutions in water and without soil
Aeroponics - growing plants in a mist environment without the use of soil
Biotechnology - use of technology to modify organic products or processes, for example, genetically-engineering crops
New green revolution - approach to boosting food production that seeks to benefit poor farmers bypassed by the original green revolution and conserve the environment
Appropriate technology - technology suited to the needs, skills, knowledge and wealth of local people in the environment in which they live
Common misconception
The green revolution came about as a result of genetically-modified crops.
The original green revolution, in the second half of the twentieth century, came about as a result of hybridisation of existing crop varieties (and the use of pesticides). It did not employ biotechnology such as genetic modification.
Teacher tip
This lesson builds on students' understanding of agribusiness introduced in the lesson about food resources in the UK.
