Since the 1970s, the number of rice varieties in India has plummeted from roughly 100,000 to 7,000. The massive drop is largely due to the rise of high-yield crops born from the Green Revolution, which helped relieve a strained food supply. However, the extinct rice varieties don’t just signify a loss of heritage and cultural identity in Indian villages – each lost variety is a small defeat in the battle to preserve biodiversity and genetic variation. The ecologist Dr Debal Deb has a creative solution to his country’s vanishing rice problem: a massive seed bank that houses and preserves rare indigenous rice before it disappears.
