Question

Answer

Rooftop Rainwater Harvesting in Meghalaya
Rooftop rainwater harvesting is a sustainable practice that captures rainwater from rooftops for various uses, particularly in regions where water scarcity is a concern. This method is notably prevalent in Meghalaya, a northeastern state of India.
Key Features of Rooftop Rainwater Harvesting in Meghalaya:
- Abundant Rainfall: Meghalaya is one of the wettest places on Earth, receiving heavy monsoon rains. This makes it ideal for rainwater harvesting.
- Traditional Practice: The local communities have traditionally used rooftop rainwater harvesting systems to supplement their water supply, especially during dry spells.
- Community Engagement: Villagers often come together to construct and maintain rainwater harvesting systems, fostering a sense of community and cooperation.
- Water Quality: The collected rainwater is generally clean, making it suitable for drinking and domestic use after appropriate filtration.
- Environmental Benefits: This practice helps in groundwater recharge, reduces runoff, and minimizes soil erosion.
Conclusion
In contrast to other regions, such as Tamil Nadu or Rajasthan, where different irrigation and water conservation techniques are employed, Meghalaya stands out for its effective use of rooftop rainwater harvesting, making option 'C' the correct answer. This system not only addresses local water needs but also promotes environmental sustainability and community participation.

Option D: Bamboo Drip Irrigation - Kerala: This is incorrect. Bamboo Drip Irrigation is a traditional system prevalent in Meghalaya, not Kerala.
Thus, the correctly matched pair is Option C: (c) Rooftop Rainwater Harvesting - Meghalaya.
