- Mwea Irrigation Scheme, Kenya, is a large-scale agricultural development with advantages and disadvantages.
Vocabulary To Learn
- 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 Mistakes To Avoid
- The green revolution came about as a result of genetically-modified crops.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
Different strategies can be used to increase food supply. Strategies to increase food supplies include irrigation, aeroponics and hydroponics.
2. Define this geography term and use it in an example. 'hydroponics'
growing plants using mineral nutrient solutions in water and without soil.
3. Correct this common geography misunderstanding.
Mistake: The green revolution came about as a result of genetically-modified crops. Correction: 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.
