​In a mountainous region in east China’s Anhui Province, Fang Guoqiang stands out among people who have been working on the frontline to preserve the environment and achieve sustainable development. For more than two decades, he has promoted the idea and practice of green farming among his fellow villagers in the headwater region of the Xin’an River, a major waterway in east China. This green farming has in turn contributed to the local ecological conservation while increasing the income of farmers.
