Gabriella D’Cruz, from Goa, wants to improve diets, transform livelihoods, and protect the planet using an often-overlooked marine vegetable - seaweed. Ruth Alexander speaks to the 29-year-old about her big plans for the underwater crop, and her hope that it could bring lasting economic and environmental change to India’s coastal communities. Gabriella’s passion and her project’s potential saw her chosen by a panel of international judges as the winner of The Food Chain Global Youth Champion Award 2021.
