In 2017, Chang Tianle launched Foodthink 食通社, an online media organisation focused on promoting sustainable food systems. With Foodthink, Tianle is building on a decade of work on sustainability and social justice, including her launching and running Beijing Farmers’ Market since 2010. 

Tianle and her team have made Foodthink an information and knowledge hub for people in the sector. It also provides offline and online courses, supports grassroots activism, advocates for policy changes and engages in international exchange around sustainable food. To address knowledge gaps, the Foodthink team has also produced original reports on the links between small-scale ecological farming and agrobiodiversity, and climate change experiences and adaptation by smallholders in China.
