The_technique is quite expensive, it is an excellent irrigation technique for areas where there is scarcity of water.

Options

A. Sprinkler system
B. Drip irrigation
C. Pulley system
D. Lever system

Answer

**Step-by-Step Solution:**

1. **Identify the Context**: The question refers to an irrigation technique that is effective in areas with water scarcity.

2. **Consider the Options**: The video discusses several irrigation techniques:
- Sprinkler System
- Drip Irrigation
- Pulley System
- Lever System

3. **Analyze Each Technique**:
- **Sprinkler System**: This is used in uneven terrains and is not suitable for areas with very low water availability.
- **Drip Irrigation**: This technique delivers water directly to the roots of plants in a drop-by-drop manner, minimizing water wastage. It is highly efficient in water-scarce areas.
- **Pulley System**: This system involves drawing water from a source and distributing it, which can lead to higher water usage.
- **Lever System**: Similar to the pulley system, it also requires more water and is not as efficient in water-scarce regions.

4. **Conclusion**: Based on the analysis, the drip irrigation technique is the most suitable for areas with water scarcity due to its efficiency in water usage.

5. **Final Answer**: The technique referred to in the question is **Drip Irrigation**.
