China has constructed or upgraded a total of 460 million mu (about 30.67 million hectares) of high-standard farmland, supported by the funding of over 700 billion yuan (about 99.26 billion U.S. dollars) from the central government finance, during the 14th Five-Year Plan period (2021–2025), according to the Ministry of Agriculture and Rural Affairs.
This large-scale initiative has significantly bolstered national food security, the ministry said.
High-standard farmland is characterized by well-leveled, contiguous plots with advanced irrigation, efficient water use and enhanced soil fertility. Designed to withstand both droughts and floods, it aligns with modern agricultural practices and features pollution-free soils and high yields.
Throughout the 14th Five-Year Plan period, local governments prioritized the construction of high-standard farmland in key regions, including the black soil region in northeast China, major plains, areas with established irrigation infrastructure, and zones with high grain output or strong production potential. Efforts were made to promote gradual transformation of eligible permanent basic farmland into high-standard farmland, according to ministry data.
Under the guidance of the Ministry of Agriculture and Rural Affairs, local authorities have made great efforts in leveling field plots, upgrading irrigation and road networks, and enhancing soil quality, showed the data.
To ensure construction quality, the ministry has dispatched taskforces to carry out routine inspections as part of standardized oversight efforts.
Early results show that the upgraded farmland has significantly strengthened agricultural productivity and resilience. Previously fragmented or underperforming plots, once vulnerable to weather extremes and inconsistent yields, now benefit from integrated infrastructure, enabling reliable irrigation during droughts and effective drainage during floods.
In many regions, high-standard farmland now routinely achieves yields of 7.5 tons per hectare per crop growing season.

The return capsule of the debris-hit Shenzhou-20 spaceship landed safely back on Earth on Monday, with ground search teams overcoming the unique challenges of locating and retrieving the unmanned craft as China's first emergency space mission came to a successful conclusion.
The China Manned Space Agency (CMSA) confirmed the capsule touched down safely at the Dongfeng Landing Site in north China's Inner Mongolia Autonomous Region at 09:34 local time on Monday morning, bringing an end to the extraordinary mission.
Launched from the Jiuquan Satellite Launch Center last April, Shenzhou-20's return was postponed in early November due to concerns over damage caused by a suspected space debris impact, after the CMSA said tiny cracks were found in the Shenzhou-20 return capsule's viewport window.
An alternative spacecraft was later used to transport the three Chinese astronauts of the Shenzhou-20 mission safely back to Earth.
Monday's return began shortly after midnight Beijing time, when the spaceship undocked from the Tiangong space station and began its descent.
Despite sustaining damage, the capsule withstood temperatures of thousands of degrees Celsius during the re-entry process and successfully returned to Earth after in-orbit reinforcement and sealing work carried out by the Shenzhou-21 astronauts, who arrived to take over duties from the Shenzhou-20 crew in November.
Xu Peng, the on-site commander at the Dongfeng Landing Site, said that this particular unmanned landing represented a whole new set of challenges to the search and recovery teams on the ground.
He said the ground search forces made targeted adjustments in order to better cope with the extreme weather conditions in the area, with frigid temperatures and strong winds posing further difficulties to retrieving the return capsule.
"This marks the first time the Dongfeng Landing Site has carried out a spaceship recovery mission during the coldest season of the year, with cold weather posing a test for both our search and rescue teams and equipment. We made special cold-protection preparations in advance to ensure that both personnel and the equipment remained in good condition throughout the mission," Xu said.
Xu also noted another unique factor of this unmanned return which put extra pressure on the ground teams to respond quickly to its touchdown.
"As the Shenzhou-20 return capsule was unmanned, there was no astronaut to manually separate the parachute. As a result, the main parachute did not automatically detach upon landing, and in strong winds, it could have dragged the return capsule along the ground. This requires our ground personnel to reach the landing point and cut the parachute as quickly as possible. ," Xu said.
Ground teams were keen to secure the spacecraft as quickly as possible so that a comprehensive assessment can be made on the damage it sustained in space which necessitated the emergency response operation.
On-site personnel promptly took steps to protect the damaged porthole on the return capsule upon its landing, which will provide essential data for the optimization of key spaceship components in the future.
Additionally, Xu said the ground teams deployed new methods, such as drones and other high-tech equipment, to assist in this unprecedented recovery operation.
"Adjustments were made to our recovery forces. The helicopter unit did not participate in this mission, and the drone and unmanned ground vehicle units made their debut. This new model, combining unmanned search equipment with ground personnel, was applied in the recovery of the uncrewed capsule," he said.
Though without any crew members, the return capsule was instead carrying several space application system items from the space station, including a well-used spacesuit which had far exceeded its service life while supporting some 20 extravehicular activities during space missions.
Monday's mission came after the three Shenzhou-20 crew members jointly met with the press in Beijing on Friday after completing their standard isolation period following their delayed return in November, with experienced mission commander Chen Dong hailing the calm and methodical response to the debris incident and the coordination with teams on the ground which ensured the trio got home safely.
