Their systems? Rice + fish in sync. Bamboo pipes that drip water like nature’s IV. Forests that feed fields. But climate change is quietly breaking all of it. Monsoons now arrive late, streams dry up mid-season, and pests attack crops that never used to fail. Despite this, communities aren’t waiting for aid; they’re reviving ancient methods like planting ten families of beneficial insects to fight pests, switching to drought-proof tubers, and redesigning terraces to survive flash floods. These aren’t 'old techniques'; they’re survival blueprints. And as India pushes for natural farming, the real lessons might lie not in labs, but in the hills of Arunachal, Meghalaya, and Nagaland; where tradition is now the frontline of climate resilience.
