Explanation
A community-led approach uses traditional knowledge and gives people shared ownership of the water source, which is its main advantage over a top-down method.Assertion (A): Indigenous water harvesting systems in Rajasthan have demonstrated remarkable resilience and sustainability over centuries.
Reason (R): These systems were scientifically adapted to specific local topographical, climatic, and geological conditions using locally available natural materials.
Which of the following is correct?
Explanation
Rajasthan’s traditional water systems have lasted for centuries because they were suited to the local terrain, climate and geology and were made with local materials. The reason explains the assertion.Explanation
Palar Pani is direct rainwater, the purest form, and Patal Pani is deep groundwater. Rejani Pani is sub-surface water trapped above the deep saline layer, not saline stagnant surface water, so C is the incorrect pair.Explanation
Rejani Pani is sub-surface moisture trapped above hard rock or the saline layer, and it is taken out through Kuins.Explanation
Palar Pani, Patal Pani and Rejani Pani are the three traditional categories of water in the Thar. Bisleri Pani is a modern packaged-water brand, so it is the odd one out.I. Observing the presence of specific deep-rooted vegetation like the Khejri or Rohida trees.
II. Analyzing the moisture content and color of termite mounds.
III. Using advanced satellite ground-penetrating radar.
IV. Observing the behavioral patterns of local wildlife and grazing animals.
Which of the above statement(s) is/are correct?
Explanation
Local people judged the likelihood of groundwater from deep-rooted trees such as Khejri and Rohida, from termite mounds and from how animals behaved. Satellite ground-penetrating radar is not a traditional method.Statement I: Nomadic pastoral communities in Rajasthan possessed deep indigenous knowledge of traversing long distances by relying on a hidden network of natural springs and traditional dug wells.
Statement II: The routes taken by pastoralists purposefully avoided all water sources to prevent taxing the local village resources.
Which of the following is correct?

Pastoralists knew a hidden network of springs and wells that let them cross long distances, so Statement I is true. They relied on water sources rather than avoiding them, so Statement II is false.I. Stepwell (Baori)
II. Village Pond (Nadi)
III. Underground Cistern (Tanka)
Explanation
