Protecting farmland and ecology and developing agricultural technologies are essential for nation's long-term grain security

Despite a continuing increase in its grain output in recent years, China should make efforts to keep its arable land from dwindling in order to maintain its grain security.

China's total grain output increased for the eighth consecutive year in 2011, reaching 550 billion kilograms. Experts have attributed these bumper harvests to the government's pro-agriculture policies and measures, favorable climate conditions and the hard work of the nation's farmers.
