The correct answer is: d) All of the above.
Watershed management is the process of planning and implementing activities to protect and restore watersheds. It includes activities such as reforestation, erosion control, and water quality monitoring. Rainwater harvesting is the collection and storage of rainwater for later use. It can be used for drinking, irrigation, and other purposes. Drip irrigation is a method of irrigation that delivers water directly to the roots of plants. It is a more efficient method of irrigation than traditional methods, such as flood irrigation.
All of these efforts can help to improve water conservation in Mizoram. Watershed management can help to reduce runoff and erosion, which can lead to the loss of water. Rainwater harvesting can help to collect water that would otherwise be lost, and drip irrigation can help to use water more efficiently.
In addition to these efforts, there are other things that can be done to improve water conservation in Mizoram. These include:
- Reducing water consumption: This can be done by taking shorter showers, fixing leaks, and using water-efficient appliances.
- Recycling water: This can be done by collecting rainwater, using gray water, and installing a water recycling system.
- Protecting water resources: This can be done by planting trees, reducing pollution, and conserving wetlands.
By taking these steps, we can all help to improve water conservation in Mizoram.
