China is addressing the intricate task of harmonizing food security, land use, and sustainability amid mounting climate challenges. To tackle the pressing demand for food, China is enacting strict controls on farmland use, emphasizing compensation for lost crop output capacity when conversion is necessary. Concurrently, the government encourages initiatives like solar farms on unused land, but stringent regulations ensure they don’t encroach on vital agricultural and ecological areas. Balancing these priorities is essential as China grapples with climate-induced threats to its food system and strives to build a sustainable future.

Climate Change Challenges for China’s Arable Land
China’s agricultural landscape faces dire challenges, with climate change wreaking havoc on its arable land. A staggering 8 percent of the nation’s wheat-producing land, equivalent to 1.9 million hectares or 19,000 square kilometers, has fallen victim to an extended period of relentless rainfall, as per official data. This ongoing bout of unpredictable weather is expected to continue plaguing the agricultural sector for the rest of the year.
Climate Change and Its Impact on Chinese Farming
The repercussions of climate change on China’s farming industry are not lost on global institutions. The United Nations’ Intergovernmental Panel on Climate Change (IPCC) and the World Bank both highlight the inevitable increase in loss and damage across the country’s agricultural sector as global temperatures continue their upward trajectory. But what are the specific challenges that China’s arable land faces, and what strategies does the nation have in place to mitigate these adverse effects on its overall food production system?
From Crops to Pork: Climate Change’s Multifaceted Impact
The impact of climate change on Chinese farming has been grim in recent years. In 2022, China experienced its most severe heatwave and drought in over six decades. Last August, the Ministry of Agriculture and Rural Affairs held a press conference, where they highlighted the increasing risks faced by the agricultural sector. These risks stem from extreme weather events and shifting planting conditions induced by climate change.
This summer, China continued to grapple with Mother Nature’s unpredictability. June and July brought severe drought conditions, while August saw torrential floods, a consequence of typhoons. These relentless rains have taken a toll on corn and rice crops in the north. In central China’s Henan province, the losses were staggering, with over 20 million tonnes of wheat wiped out in June alone.
China’s recent agricultural performance paints a mixed picture. Despite the agriculture ministry’s insistence on a “summer harvest,” the numbers tell a different story. Summer grain output has dipped by 2.55 billion jin (equivalent to 1.53 million tonnes) compared to last year’s robust total of 147 million tonnes.
However, the US Department of Agriculture offers a glimmer of hope for 2023. It suggests that this year might not be entirely bleak for China’s harvest. Only sunflower seeds, barley, and cotton are expected to witness reduced production. The primary crops, including corn, rice, and wheat, are anticipated to surpass the five-year average.
Corey Lesk, a research associate at Dartmouth College in the US, offers an intriguing perspective. He notes that China’s crops may not be as susceptible to climate warming as one might think. China’s primary food crops, wheat in the north and rice in the south, display varying levels of resilience to extreme heat. The southern regions, already warm and sub-tropical, are better equipped to handle such conditions.
In the north, warming trends could extend the growing season, enhance wheat yields, and enable multiple crop cycles at higher latitudes. Consequently, crop models suggest that in the north, the impact of plausible warming scenarios on yields would be relatively minor.
Haishun Yang, an associate professor at the University of Nebraska – Lincoln, concurs with this perspective, highlighting that globally, crop yields and total production have steadily risen alongside climate change.
However, Lesk injects a note of caution, pointing out that these crop models tend to underestimate the true consequences of extreme heat, a crucial aspect of climate change.
The latest IPCC report underscores the significant impact of climate-related extremes on agriculture and fisheries worldwide, with adverse implications for food security and livelihoods. China is no exception to these challenges.
Dr. Zhang Hongzhou, a research fellow at Nanyang Technological University, Singapore, echoes this sentiment. He emphasizes that more frequent extreme climate events like floods, droughts, and typhoons pose substantial risks to China’s food security, both in the short and long term. While certain regions and crops may benefit from a warmer climate, the overall outlook remains pessimistic. In essence, climate change poses a substantial threat to China’s food security.
