Planting and harvest operations across China’s main grain belt face disruption because heavy rains have arrived earlier than usual. The National Meteorological Center has forecast heavy rainfall in late May and early June for provinces including Henan, Hebei and Anhui, while intense downpours in the south could damage early-season rice, vegetables and fruit trees. During the May Day holiday the Ministry of Emergency Management convened joint consultations with agencies for meteorology, water resources and natural resources and coordinated prevention plans with provinces from Guangxi to Guizhou. Officials say the timing coincides with critical planting and harvesting stages and raises the risk of local flooding and agricultural losses into early June.

484 million yuan. That's the sum Beijing put into agricultural disaster relief in 2025 to speed up harvesting, dry damp grain and drain waterlogged farmland after what the National Climate Centre called the longest and heaviest rainy season in six decades for major grain provinces including Henan and Shandong.

Central forecasts and government coordination

The immediate threat now isn't a single storm but a broad rain system. The Central Meteorological Observatory said a widespread rain band affected the Qinghai-Tibet Plateau, North China, South China and eastern parts of northwest China in early May, and that the heaviest falls were concentrated south of the Yangtze River and across central and northern parts of South China. In its latest outlook the National Meteorological Center expects heavy showers across key grain provinces in late May and early June.

That outlook has prompted urgent inter-agency action. The Ministry of Emergency Management, working with meteorology, water resources and natural resources agencies, held a joint consultation during the May Day holiday and coordinated prevention plans with provincial authorities in Guangxi, Hunan, Jiangxi, Anhui, Fujian and Guizhou. Local emergency authorities were urged to reinforce responsibilities, step up risk checks and improve early-warning systems, the ministry said, after water levels in several small and medium rivers already exceeded warning thresholds since the start of the flood season.

The Ministry of Water Resources has added a complicating element: a dual climate threat for 2026. It warned of significant flooding risks in northern basins while parts of the Yangtze corridor face drought pressure, an unusual juxtaposition that complicates national water management, reservoir operations and the allocation of emergency resources.

Government concern about crop losses is grounded in recent experience. The National Climate Centre reported that in 2025 Henan and Shandong endured their longest and heaviest rainy season in six decades, leaving large areas waterlogged and disrupting harvesting.

Mastheads

In response the central government allocated the 484 million yuan relief package to speed up harvesting, dry damp grain and drain waterlogged farmland.

Vice Premier Liu Guozhong has called for urgent measures, saying authorities must do "everything possible" to safeguard the harvest and national grain procurement targets. That instruction reflects two pressures. First, heavy, prolonged rain can halt harvest operations and reduce labour productivity in the fields. Second, wet conditions reduce grain quality in storage, complicate post-harvest drying and raise the cost and logistical complexity of relief and recovery.

Southern provinces that grow early-season rice and horticultural crops are especially exposed. Intense downpours at this time of year can damage rice seedlings, rot vegetables and snap fruit-tree blossoms, cutting yields before the crop has had a chance to recover.

Northern provinces are exposed for different reasons. Unusually wet conditions can overwhelm ageing drainage and river-control infrastructure, sending water onto land not designed for prolonged inundation and forcing emergency releases from reservoirs that may affect downstream communities.

Officials are thus balancing two sets of tasks: protecting fields during sensitive cultivation or harvest windows, and managing river basins and reservoirs so flooding in one region doesn't deepen drought in another. That's precisely the policy headache the Ministry of Water Resources described when it flagged flood risk in northern basins and drought pressure along parts of the Yangtze corridor.

Practical steps under way include stepped-up risk checks on river systems, reinforcement of flood defences where possible, and improvements to early-warning systems that local emergency teams can act on. The ministry-level coordination that took place over the holiday was designed to ensure provinces most under threat have pre-positioned equipment and clear operational plans should heavy rain and local flooding materialise.

Past seasons show why speed matters. When harvest operations are delayed, not only do yields fall but the window for drying and storage narrows. That raises the chance of spoilage, which in turn forces larger relief budgets and more complex logistics to move, dry and rehouse grain. The recent memory of 2025, and the central relief allocation that followed, is shaping the urgency of this year's response.

For farmers on the ground the week-by-week weather matters. For planners in Beijing the important fact is systemic: a rain pattern that arrives early and persists across the grain belt coincides with multiple sensitive crop stages and forces authorities to draw on finite emergency resources across a wide geography.
