Statement I: Kunds were traditionally constructed to store rainwater strictly for drinking purposes, especially in regions with highly saline groundwater.
Statement II: The water collected in a Kund is considered pure as the catchment area is kept scrupulously clean and is off-limits to livestock.
Which of the following is correct?
Explanation
Kunds were specifically designed to provide high-quality drinking water in areas where groundwater is often saline. To maintain this purity, the catchment area is kept extremely clean and protected from any activity that could cause contamination. The local communities strictly prevent livestock from entering the Agor, ensuring that the collected rainwater remains safe for human consumption throughout the long dry seasons.I. The Gram Panchayat Secretary is solely responsible for writing and finalizing the Social Audit report.
II. The Social Audit unit must be entirely independent of the implementing agency.
III. Observers from the state government or civil society often attend the public hearing.
IV. Findings of the audit must be uploaded to a public management information system (MIS).
V. If corruption is identified during the audit, the Gram Sabha has the power to directly sentence the offenders to prison.
Which of the above statement(s) is/are incorrect?
Explanation
The independence of a social audit is compromised if the Gram Panchayat Secretary, who is part of the implementation, finalizes the report. Additionally, while the Gram Sabha can identify corruption and recommend actions, it does not possess the judicial power to sentence offenders to prison. Legal punishments must be handled through the formal criminal justice system and relevant administrative disciplinary procedures.I. Rooftop rainwater harvesting is primarily an urban phenomenon in modern times.
II. RWH helps in reducing peak storm runoff and thus mitigates urban flooding.
III. It strictly involves the storage of water in surface tanks without any groundwater recharge.
IV. The Central Ground Water Board highly recommends RWH to tackle overexploited dark zones.
Which of the above statement(s) is/are correct?
Explanation
Rooftop rainwater harvesting is a common urban practice that helps reduce storm runoff and mitigate flooding. The Central Ground Water Board strongly advocates for these systems to recharge depleted aquifers in overexploited zones. However, RWH is not limited to surface storage; it often involves direct injection into the ground to replenish groundwater levels, making the third statement factually incorrect.Explanation
Article 270 of the Indian Constitution is the legal foundation for the sharing of net proceeds of most central taxes between the Union and the states. This mandatory devolution ensures that states like Rajasthan receive a predictable share of national revenue. These funds are crucial for financing state-specific development projects and maintaining essential public services across the expansive geographic territory of the state.| Structure | Structural Characteristics |
|---|---|
| A. Kund | i. Subterranean stepwell with architectural flights of stairs |
| B. Baori | ii. Saucer-shaped artificially treated catchment leading to a pit |
| C. Khadin | iii. Earthen check dam for surface storage and groundwater recharge |
| D. Johad | iv. Long earthen embankment built across the lower hill slopes to farm runoff water |
Explanation
Rajasthan’s traditional water structures are defined by their unique engineering features. A Kund uses a saucer-shaped catchment leading to a pit, while a Baori is a subterranean stepwell with stairs. A Khadin is an earthen embankment built across slopes for runoff farming, and a Johad is a small check dam used for surface storage and facilitating groundwater recharge in local aquifers.Explanation
Funding for social audits under MGNREGA is designed to ensure independence. A fixed percentage of the administrative costs is allocated by the central government specifically for this purpose. This ensures that the Social Audit Unit has the financial resources to operate without being dependent on the implementing agencies. State governments are not barred from contributing; rather, the focus is on maintaining autonomous funding.Explanation
The fundamental distinction between these two types of irrigation lies in their source and extraction method. Surface water irrigation involves utilizing water from rivers, lakes, or reservoirs through a network of open canals and channels. In contrast, groundwater irrigation involves extracting water stored in underground aquifers through the use of traditional wells, tube wells, or borewells equipped with mechanical pumps.Explanation
The 15th Finance Commission used several criteria for distributing central taxes, with the "Area" criterion proving highly beneficial for a geographically large state like Rajasthan. Because Rajasthan is the largest state in India by land area, it receives a higher weightage in the horizontal devolution formula. This allocation helps compensate for the higher costs associated with providing public services across sparsely populated regions.Explanation
To maximize the efficiency of a Kund, the catchment area or Agor must be treated to ensure high runoff. Traditionally, this involves plastering the surface with materials like lime, ash, or a mixture of mud and gravel. This creates a hard, impervious layer that prevents water from soaking into the ground, instead directing almost all rainfall into the central storage cistern.Answer key for these questions
