From the Public Sector to a Frontline NGO: An Idealist in Yunnan

How does an organisation devoted to insect ecology come to care about farmers’ livelihoods? And how does an organisation devoted to farmers’ livelihoods end up composing a “Song of the Flies“?

How did a man from Shanxi become the village’s “male Women’s Director”? And why would a top graduate in genetic engineering be out in the fields urging farmers to ditch pesticides and chemical fertiliser?

How do all these seemingly unrelated people and events wind up stitched together in such a remarkable way?

In this episode, we welcome Zuo Zhi, Executive Director of the Yunnan Sili Ecological Alternative Technology Centre. A member of the post-1985 generation who went from Shanxi into the villages of Yunnan, he chose, after graduating from university, to walk away from his public-sector career and join an NGO called “Sili”, doing something not so easy to explain, out in the fields: teaching farmers to use fewer pesticides and grow heritage rice varieties, and trying to build a bridge between government, farming households and technology.

You will hear some counterintuitive details: flies turn out to be the top “matchmakers” in mango orchards, and the first step in promoting ecological agriculture is actually downing the cup of liquor a farmer presses into your hand. From the Dali Rice Transplanting Festival to the yield-measurement sites among the Hani rice terraces, Zuo Zhi guides us through the dynamics between agricultural input shops, agricultural technology stations and civil-society organisations, breaking down what “climate-friendly rice” truly means — rice that maintains yields while cutting emissions.

In this episode, together with Zuo Zhi, we record how an idealist reaches the ground level by “speaking plainly”. This is not just a primer on “climate-friendly rice”; it is a true account of how, amid real-world constraints, small changes can build trust and keep watch over the countryside.
