Needs Address
- Risk reduction
- Increased agricultural productivity
Adaptation effects
- Reduces the risk of complete crop failure due to drought or untimely heavy rainfall
- Avoids loss of crops due to variations in climate
- Can take advantage of the early production of crops by growing further additional crops once original crop has been harvested
Overview and Features
Substituting crop varieties to those more suitable for altered climatic conditions
Cost
Cost of different seeds and cropping methods, if applicable
Energy source
Human labour
Ease of maintenance
Dependent on chosen crop
Technology performance
Has been shown to be effective when appropriate crops are selected
Considerations
Requires knowhow and a detailed understanding of soil interactions
Co-benefit, suitability for developing countries
- Higher crop yields
- Low costs mean this option is very suitable
- Must be supported by knowledge provision and capacity to experiment (demonstration, piloting)
