The North China Plain (NCP) is a remarkable agricultural area with severe water scarcity and uneven precipitation, especially in wheat season. Optimizing irrigation strategies to increase productivity (WP) achieve higher yield winter wheat-summer maize rotation urgently needed has been persistent challenge. A four-year field experiment was conducted explore the impact of on WP subsequent under different precipitation year types (dry normal years, categorized based cumulative from sowing jointing stage (P1)). Four (W0, no irrigation; W1, pre-sowing W2, + W3, anthesis irrigation) were adopted for wheat, identical operations applied maize. Results showed that affected by P1 rather than total precipitation. Irrigation improved enhancing evapotranspiration, spike number, grain 1000-seed weight. water-limited gap between W2 W1 significantly those W0, W3 implying suitable strategy production. Different season had effect but increased 13.2–29.3% 16.1–41.8% compared other treatments through decreasing soil storage before dry years. Therefore, we recommended annual yield, WP, net income years (37.6 mm < 79.9 mm); lower consumption economic benefits (P1 37.6 mm), respectively. Overall, optimizing conditions an effective cope resource shortages crop NCP.

Abstract Irrigation has distinct impacts on extreme temperatures. Due to the carryover effect of soil moisture into other seasons, temperature irrigation are not limited irrigated seasons. Focusing North China Plain, where occurs in both spring (March‐April‐May) and summer (June‐July‐August), with a higher proportion water applied during spring, we investigate impact heat events. Based partial correlation analysis data products, find positive correlations between moisture, suggesting that irrigation‐induced surplus persists following affects regional climate by impacting surface energy partitioning. Regional simulations confirm cross‐seasonal climatic effects show reduces frequency intensity events approximately −2.5 days −0.29°C, respectively. Our results highlight importance mitigating extremes.

Long-term rotary tillage limit water infiltration and crop productivity in North China Plain (NCP). The practice of subsoiling to fracture plow pans has made beneficial impacts on soil surface structure infiltration. Further, appropriate irrigation method coupled with regime can improve condition. A three-year field trial (2020–2023) was carried out assess the effects winter wheat evapotranspiration (ET), grain yield (GY), (WP), partial factor from applied nitrogen (PPFN), economic analysis. three regimes were irrigated when moisture levels decreased 70%, 60% 50% capacity (referred as H, M L) two methods drip (SDI) micro-sprinkler (MSI). traditional flood 70% filed CK. results showed optimizing significantly influenced ET, GY, WP, PPFN, net incomes. As amount increased, ET first increased while incomes then slightly decreased. Based average, maximum GY 9454 kg ha−1 income 11089 yuan achieved SDI-M, which had WP 2.3 m−3 PPFN 39.4 kg−1. At same time, SDI-M did not result much increase (average 405.1 mm seasons). Considering comprehensively incomes, irrigate decreases by optimal strategy all aspects. These will provide a scientific reference for management NCP, well similar production areas worldwide.

The Budyko water balance is a fundamental concept in hydrology that links aridity to how precipitation divided between evapotranspiration and streamflow. While the model powerful, its ability explain temporal changes influence of human activities climate change limited. Here we introduce causal discovery algorithm explore deviations from balance, attributing them interventions such as agricultural snow dynamics. Our analysis 1342 catchments across U.S. Great Britain reveals distinct patterns: U.S., fraction irrigation alter predominantly through aridity-streamflow relationships, while Britain, are primarily driven by precipitation-streamflow notable with high cropland percentage. By integrating enhance understanding dynamics affect offering insights for management sustainability Anthropocene. influenced irrigation, driving dynamics, according an 1,342 catchments.

Emission reduction, heat mitigation, and improved access to water food provision are increasingly critical challenges for urban areas in the context of global climate change adaptation mitigation. The revival local agricultural production is often lauded as a potential nature-based solution. However, an expansion peri-urban agriculture (peri-UA) may entail significant ecosystem trade-offs. This study explores impacts on food-water-climate nexus different scenarios semi-arid, Mediterranean climate, addressing provision, freshwater use, temperature regulation, trade-offs thereof.

Abstract Remarkable vegetation greening has been observed in the Yangtze River Basin (YRB) during past two decades, triggering noteworthy hydrological consequences. Previous studies have assessed effect of but ignored vegetation‐precipitation feedbacks from land‐atmosphere interactions. To address this knowledge gap, here we conduct coupled model simulations prescribed with satellite observations to investigate how YRB affects regional cycles through physiological processes and biophysical feedbacks, potentially competing effects on water yield (WY) by altering evapotranspiration (ET) precipitation. Over 2001–2020 period, leaf area index summer shows a significant increasing trend at rate 0.34 m 2 −2 decade −1 ( P < 0.01). This causes substantial rise ET, primarily due increased plant transpiration canopy evaporation, along reduced soil evaporation attributed enhanced root uptake shading surface. Moreover, modeled results indicate that is key driver for ET enhancement. In addition, induces increases precipitation modulating moisture flux convergence, which although statistically insignificant, provides considerable compensate ET. For cumulative 2001 2020 basin scale, (approximately, 101 mm) outpaces consumption 93 mm), resulting an insignificant WY. Our findings underscore importance considering evaluations response natural or deliberate changes.

Abstract. Intensive irrigation is known to alleviate crop water stress and alter regional climate, which can in turn influence air quality, with ramifications for human health food security. However, the interplay between irrigation, climate pollution especially simultaneously intensively irrigated heavily polluted regions China has rarely been studied. Here we incorporated a dynamic scheme into climate–air quality coupled model examine potential impacts of on ozone (O3) fine particulate matter (PM2.5) China. Results show that increases PM2.5 by 12 µg m−3 (28 %) but reduces O3 concentration 3–4 ppb (6 %–8 %). Among PM2.5, nitrate ammonium aerosols rise 70 % 40 %, respectively, upon introducing secondary formation contributing ∼ 60 10 %–30 respectively. High humidity low temperature promote aerosols. To mitigate these adverse effects found 20 reduction NH3 NOx emissions more effective compared individual emission reductions, while enhancement due be completely offset itself. Our study highlights benefits regarding problems under currently prevalent modes anthropogenic scenarios, emphasizing need an integrated approach balance conservation, pollution, change mitigation security face development needs.
