China vows self-sufficiency in grain production
Solutions to the problem include rearranging crop growth in some heavily polluted regions, converting overexploited farmland to forest, and more fiscal investment to mitigate negative impacts, Tang said.
"How to transform agricultural development and make it sustainable has become a pressing issue for China," Chen said.
A policy document issued on Sunday by China's top authorities is designed to address the challenges.
It said that China will enhance its national food security, deepen reforms and improve rural governance, and step up financial support and protection for agriculture.
The document, the 11th of its kind since 2004, detailed a raft of measures and reforms related to the "three rural issues" -- agriculture, rural areas and farmers. It aims for greater achievements in agricultural modernization and progress in building the "new countryside."
