Which of the following pairs of after effects are considered to be consequences of the Green Revolution ?

Options

A. waterlogging and soil salinity
B. soil erosion and desertification
C. deforestation and jhu, cultivation
D. ozone depletion and global warming

Answer

### Step-by-Step Text Solution

1. **Understanding the Green Revolution**: The Green Revolution refers to a series of research, technology transfer initiatives, and agricultural practices that took place between the 1950s and 1960s. It aimed to increase agricultural production worldwide, especially in developing countries.

2. **Key Features of the Green Revolution**: The Green Revolution involved the development of high-yielding varieties (HYVs) of crops, particularly dwarf wheat and rice. It also included the use of chemical fertilizers, pesticides, agrochemicals, controlled water supply, and mechanization in farming.

3. **Consequences of the Green Revolution**: While the Green Revolution significantly increased crop yields, it also led to several environmental and agricultural issues. Some of the notable after-effects include:
- Soil erosion due to intensive farming practices.
- Water logging and soil salinity caused by excessive irrigation.
- Loss of genetic diversity in crops.
- Soil pollution from the overuse of chemical fertilizers and pesticides.

4. **Evaluating the Options**:
- **Option 1: Water logging and soil salinity**: This is a correct pair of after-effects. Excessive irrigation can lead to water logging and increased soil salinity.
- **Option 2: Soil erosion and desertification**: While soil erosion is a consequence, desertification is not directly linked to the Green Revolution.
- **Option 3: Deforestation and zoo cultivation**: There is no significant evidence linking the Green Revolution to deforestation or zoo cultivation.
- **Option 4: Ozone depletion and global warming**: These issues are not direct consequences of the Green Revolution.

5. **Conclusion**: After analyzing the options, the only pair that accurately reflects the consequences of the Green Revolution is **Option 1: Water logging and soil salinity**.
