Spatiotemporal Heterogeneity of Long-Term Irrigation Effects on Drought in China’s Arid and Humid Regions

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(7), P. 1115 - 1115

Published: March 21, 2025

Analyzing the spatiotemporal characteristics of meteorological droughts (MD) and agricultural (AD) their propagation in different climate zones is important for effective drought management, adaptation, food security. This study takes a unique approach by comparing irrigated rainfed croplands. A comprehensive framework developed using indices, statistical analysis, trend tests, wavelet transforms. The evolution patterns, trends, correlations MD AD Xinjiang Middle-lower Yangtze Plain (MYP) are investigated. main results showed that severe events (e.g., 2005–2009 MYP 2004–2009) significantly impacted systems, leading to decline vegetation condition. Long-term irrigation can substantially alleviate under conditions. From 2000 2019, on croplands continuously improved, while deteriorated during events. In contrast, although overall was mitigated, benefits were only evident periods weakened after 2013. Correlation analyses revealed mechanisms between croplands, highlighting key role local conditions spatial heterogeneity determining efficiency. findings provide guidance optimizing management strategies, planning, sustainable water resource management.

Multidisciplinary assessment of the agricultural supply of desalinated seawater in south-eastern Spain

Desalination, Journal Year: 2022, Volume and Issue: 548, P. 116252 - 116252

Published: Dec. 1, 2022

Desalinated seawater (DSW) has provided a steady supply of agricultural water for the last decade in south-eastern (SE) Spain, overcoming climatological and hydrological constraints. This article analyses impacts progressive replacement traditional irrigation resources with DSW on main crops SE from agronomic, environmental, economic perspectives, first time. The regional magnitude spatial variability these have also been evaluated. To that end, six impact indicators were identified calculated three scenarios using increasing proportions DSW, which is representative current possible future situations. results reflect high different crops. agronomic favourable but benefits reducing salinity become saturated when exceeds 50 %. detrimental environmental due to higher specific energy consumption associated increased supply, although this not an intrinsic problem desalination since it could be mitigated renewable energies. very sensitive cost offers heterogeneous show combined use most efficient option perspectives study, rather than irrigating alone. insights study useful assessment feasibility integrating support agriculture other regions where plants are being considered supply.

Effect of Mulching on Soil Quality in an Agroforestry System Irrigated with Reused Water

Agronomy, Journal Year: 2023, Volume and Issue: 13(6), P. 1622 - 1622

Published: June 16, 2023

In this study, a special rice-energy willow/poplar agroforestry system was used to analyze the effects of reused water irrigation and mulching on soil salinity, earthworm biomass abundance, organic matter (SOM) content weed coverage in treerow-dependent habitats. After three-year-irrigation, we investigated woody line (WL), buffer zone (BZ) crop habitats (CL). Between 2019 2021, collected data distribution soil-specific electrical conductivity (EC), ammonium-lactate soluble sodium (AL-Na) exchangeable cations (Na+, K+, Ca2+, Mg2+) NO2− + NO3−-N contents from CL irrigated with effluent an intensive catfish farm. Based our results, significantly greater abundance (274 pc m−2) (54.0 g values were measured WL than BZ or There no significant difference between (0.61%) (1.91%), but weeds denser (12.3%). third year, EC, AL-Na ESP lower, SOM higher mulched (183.1 mS cm−1, 253.1 mg kg−1, 4.4 ESP% 4.597%, respectively) un-mulched soil.

The Guadalquivir Basin in Spain as a representative Mediterranean basin. aim of this study is to assess the adaptive capacity basins long periods severe drought. To do so, hydro-economic model has been developed that includes spatial representation major economic uses water and enables an analysis environmental effects alternative management policies under single event scarcity. Results highlight trade-offs among flow requirements since resources are fully allocated. Moreover, increase irrigated perennial crops area will aggravate vulnerability drought by limiting Survival irrigation first option for farmers adapt simulated extreme 148,000 ha shifted from normal survival Drought Management Protocol scenario. These findings call policy interventions ensure greater flexibility toward optimising use while meeting goals.

Supplemental irrigation mitigates yield loss of maize through reducing canopy temperature under heat stress

Agricultural Water Management, Journal Year: 2024, Volume and Issue: 299, P. 108888 - 108888

Published: May 23, 2024

Due to global warming, high temperature stress severely impacts maize growth and development, especially during the early filling stage. Supplemental irrigation is an effective measure mitigate in maize. However, underlying mechanism for alleviating transient grain-filling stage still unclear. A two-year field experiment involving (HT), supplemental under (HTW), control condition (W), treatment (CK) by using heat-tolerant variety ZD958 heat-sensitive XY335 was conducted. Compared with CK treatment, HT significantly decreased activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT). also reduced Pn, soluble sugar content stem, dry matter accumulation, thus reducing kernel number per ear yield 11.2–17.6% 23.4–23.7% both variety, respectively. compared HT, HTW daily mean canopy 2.6 °C 2.8 °C, Accordingly, increased SPAD value, photosynthetic performance, starch sugars stems leaves, antioxidant enzymes activities, but malondialdehyde (MDA). Moreover, grain sink capacity, prolonged days 1.4–6.5 d, average rate 14.8–41.0% HT. Finally, 15.8–22.3% Therefore, could effectively enhanced heat resistance reduce temperature. This study provides important insights into enhancing stability a warming climate.
