It is crucial to elucidate the impact of climate change on wheat production in China. This article provides a review current scenario and its effects cultivation China, along with an examination potential future impacts possible response strategies. Against backdrop change, several key trends emerge: increasing temperature during growing season, raising precipitation, elevated CO 2 concentration, diminished radiation. Agricultural disasters primarily stem from oscillations northern region being mostly affected. The manifested reduction area under cultivation, most rapid spring wheat, shift center west. Furthermore, accelerates nutritional stage shortens phenology. Climate has also led increase yields Northeast region, Northern Northwest North China winter decrease middle lower reaches Yangtze River Southwest South region. To cope Chinese can adopt adaptation strategies measures such as breeding different varieties for wheat-growing regions, implementing differentiated farmland management measures, promoting regional ecological construction, establishing scientific monitoring early warning systems. While may stimulate yield potential, it could cause climate-induced issues weeds, diseases, pests worsen, thereby posing challenges sustainability farmland.

North China Plain suffers from the world's most severe water scarcity and groundwater depletion due to intensive irrigation for agricultural production. It is imperative reduce consumption while safeguarding crop production food security. This study conducted a quantitative analysis with deficit strategies winter wheat using water-driven AquaCrop model. After model calibration validation field experimental data, we analyzed demand, yield, productivity (WP) of under various scenarios. A set optimal schedules were proposed different climate years, which significantly mitigated usage sustaining high yields WPs. The results indicated that despite demand future scenario was slightly higher than in historical period, their sensitive periods (reviving, jointing, flowering) remained same. Therefore, recommended adopting same periods. In wet 50% strategy only reduced by less 5% compared full irrigation, but it saved 1000–1100 m3 per hectare contributed WP 1.88 kg/m3. While normal dry an 25% could sustain over 96% maximum meanwhile save 650–800 m3/ha achieve almost as irrigation. These climate-smart adapting diverse climatic conditions largely mitigate maximizing use efficiency, are essential achieving precision sustainable management changing climate.

Predicting the risk of diminished wheat yields caused by drought under future climate change is essential for long-term sustainability agriculture. Although studies have explored relationship between and crop yield loss, precise thresholds triggering losses in remain unclear. In this study, we established a conditional probability framework trigger at various loss levels China's winter regions based on copula functions. The primary drivers influencing dynamics were evaluated using random forest model. results revealed that projected baseline period (1981–2020), near (2021–2060), far (2061–2100) ranged from –2.1 to –1.2, –0.8 –0.6, –1.2 –1.0, respectively, implying firstly rises then declines. This trend was primarily due increased contribution precipitation (Pre) (from 24.0% 31.5%) threshold future, coupled with decrease temperature (Tmean) 37.1% 30.4%). shift suggested Pre might alleviate adverse effect high future. average higher Southwest (–1.0 –0.6) Xinjiang (–1.1 –0.7) regions, where mild occurrences led 30% (70th percentile).

Climate change profoundly affects agriculture through increased occurrences of extreme weather events, directly affecting crop growth and food security. The North China Plain (NCP), a significant region for winter wheat production, faces challenges from the changing climate, which could threaten agricultural output sustainability. This study aimed to evaluate effects warming fluctuating precipitation, rising CO2 levels on production in NCP.
