Vandana Shiva (born 5 November 1952) is an Indian scholar, environmental activist, food sovereignty advocate, ecofeminist and anti-globalization author. Based in Delhi, Shiva has written more than 20 books. She is often referred to as "Gandhi of grain" for her activism associated with the anti-GMO movement.

Shiva is one of the leaders and board members of the International Forum on Globalization (with Jerry Mander, Ralph Nader, and Helena Norberg-Hodge), and a figure of the anti-globalisation movement. She has argued in favour of many traditional practices, as in her interview in the book Vedic Ecology (by Ranchor Prime). She is a member of the scientific committee of the Fundacion IDEAS, Spain's Socialist Party's think tank. She is also a member of the International Organization for a Participatory Society.

Vandana Shiva was born in Dehradun. Her father was a conservator of forests, and her mother was a farmer with a love for nature. She was educated at St. Mary's Convent High School, Nainital, and at the Convent of Jesus and Mary, Dehradun.

Shiva studied physics at Punjab University in Chandigarh, graduating with a Bachelor of Science degree in 1972. After a brief stint at the Bhabha Atomic Research Centre, she moved to Canada to pursue a master's degree in the philosophy of science at the University of Guelph in 1977 where she wrote a thesis entitled "Changes in the concept of periodicity of light". In 1978, she completed and received her PhD in philosophy at the University of Western Ontario, focusing on philosophy of physics. Her dissertation was titled "Hidden variables and locality in quantum theory" in which she discussed the mathematical and philosophical implications of hidden variable theories that fall outside of the purview of Bell's theorem. She later went on to pursue interdisciplinary research in science, technology, and environmental policy at the Indian Institute of Science and the Indian Institute of Management in Bangalore.

Vandana Shiva has written and spoken extensively about advances in the fields of agriculture and food. Intellectual property rights, biodiversity, biotechnology, bioethics, and genetic engineering are among the fields where Shiva has fought through activist campaigns. She has assisted grassroots organisations of the Green movement in Africa, Asia, Latin America, Ireland, Switzerland, and Austria with opposition to advances in agricultural development via genetic engineering.

In 1982, she founded the Research Foundation for Science, Technology and Ecology. This led to the creation of Navdanya in 1991, a national movement to protect the diversity and integrity of living resources, especially native seed, the promotion of organic farming and fair trade. Navdanya, which translates to "Nine Seeds" or "New Gift", is an initiative of the RFSTE to educate farmers of the benefits of maintaining diverse and individualised crops rather than accepting offers from monoculture food producers. The initiative established over 40 seed banks across India to provide regional opportunity for diverse agriculture. In 2004 Shiva started Bija Vidyapeeth, an international college for sustainable living in Doon Valley, Uttarakhand, in collaboration with Schumacher College, UK.

In the area of intellectual property rights and biodiversity, Shiva and her team at the Research Foundation for Science, Technology and Ecology challenged the biopiracy of neem, basmati and wheat.

In 1990, she wrote a report for the FAO on Women and Agriculture titled "Most Farmers in India are Women". She founded the gender unit at the International Centre for Mountain Development (ICIMOD) in Kathmandu and was a founding board member of the Women's Environment & Development Organisation (WEDO). She received the Right Livelihood Award in 1993, an award established by Swedish-German philanthropist Jakob von Uexkull.
