The Biodiversity Farmers: 6 Ways Ancient India Fed a Civilisation Without Destroying the Land

Abstract

Long before "sustainable agriculture" became a policy phrase, ancient India was already running one of the most biodiverse farming systems the world has documented. This article traces that system from its genetic roots to its near-collapse and its ongoing recovery. It opens with Nikolai Vavilov's 1920s mapping of global crop origin centres, which independently confirmed the Indian subcontinent as one of the world's richest, a conclusion classical Sanskrit agronomic texts like Krishi Parashara and Surapala's Vrikshayurveda had effectively assumed a thousand years earlier while detailing mixed cropping, soil science, and seed storage as testable technique. It examines sacred groves, 100,000 to 150,000 community-protected forest patches functioning as unofficial gene banks, and three living systems, Koraput, Kuttanad, and Kashmir's saffron heritage, that carry UN FAO certification as globally significant today. It then turns to what broke: the Green Revolution's fast, real yield gains alongside a two-decade collapse from 110,000 rice landraces to under 7,000, and the ecological costs now measurable in Punjab's soil chemistry and groundwater tables. It closes with Dr. Debal Deb's Odisha-based seed bank as a working recovery model, and with Ritu-Hita-Mita Bhoga as a personal-scale version of the same underlying principle any reader can practise today.
