R. Jaishanker, Akshay Kumar, Mritunjay Pandey · Journal of Rural Development · India

This paper proposes the "Nalanda model," a paradigm linking rural and urban women in India through grow-bag rooftop farming: rural women prepare cow dung cakes that are stacked in grow bags with a sand-dung mixture as potting material, channeled through women's collectives to urban women who fill and sell the bags to urban customers. The paper presents this as a conceptual empowerment and livelihood strategy connecting rural and urban marginalized women rather than reporting field-tested outcomes or measured results.
