Q1.
Identify modern agricultural solutions inspired by traditional practices (for example., neem-based practices).
Answer

Here are the ones the chapter itself supplies, each traced from its traditional root to its modern form.

Traditional practiceModern solution inspired by itWhat it achieves
Using neem in stores and fields to keep insects awayNeem-based pesticides“Natural and much less harmful to the environment than chemical ones”
Coating seed with cow dung before sowing (the Arthaśhāstra prescribes exactly this for cotton seed)Beejamrit, developed by ICAR — a paste of cow dung and urine with other materialsProtects seeds from being spoilt and reduces germination time
The five cow products used in households and ritualsPanchagavya — dung, urine, milk, curd and ghee, fermented“Recent studies have shown that it acts as a biofertiliser, enhancing crop growth and productivity while increasing their resistance to diseases”
Farmyard manure and cow dung to replenish nutrientsOrganic farming — compost, seed cake (the residue after oil is pressed out of seeds) and animal manureAvoids chemical fertilisers and pesticides altogether; Sikkim became the world's first 100 per cent organic state after banning chemicals in 2014
Cutting steps into hill slopes for cultivationTerracing in hilly areasCreates flat steps that “slow down water runoff and reduce soil erosion”
Mulching, and ploughing crop residue back into the fieldStill practised today, now as recognised soil conservation techniquesHolds moisture and returns organic matter to the soil
Small ponds that collect rainwater and hold moisture in the soil for longerModern rainwater harvesting and farm pondsWater available beyond the monsoon; less pressure on falling groundwater
Bamboo drip irrigation of the Northeast — water led drop by drop from a spring to each plantDrip (trickle) irrigation through tubes and emittersWater goes “slowly and directly to the plant's roots”, so almost none is wasted — the same idea, in plastic instead of bamboo
Phad systems of Maharashtra — communities sharing river water through small canalsModern canal networks and water-user associationsShares a river fairly between many farms
Intercropping and multiple cropping (seen at Kalibangan c. 2800 BCE, Fig. 1.2)Scientifically planned crop rotation and mixed croppingStops the soil from losing particular nutrients, reduces pest risk, and “ensured at least one crop”
Why so many old practices are coming back: ICAR documented almost 5000 traditional practices and tested over a hundred of them. Over 85 per cent “were validated by modern science and could be applied to reduce the use of chemicals and enhancing soil health”. In other words, these practices were not superstition — they were experiments repeated over centuries, and modern testing is confirming the results.
Tip: when you look for more examples, ask the question the chapter asks — does this method work with the natural cycle rather than against it? Feeding the soil instead of only feeding the plant, using an insect's natural enemy instead of a poison, and giving water at the root instead of over the whole field are all versions of the same idea.
