“…Natural conditions play a decisive role in soil salinization, but human activities also play a significant role, including destruction to plants, land overuse for agroforestry production, and the simplification of planting types, which result in the abandonment of cultivated land and more serious salinization (Alexakis, Gotsis, & Giakoumakis, ). There are many ways to control soil salinization, including removing redundant salt from the soil, adjusting the salt distribution in the soil profile, and preventing salt from accumulating in the soil (Akhtar, Fayyaz‐ul‐Hassan Ahmed, Hayat, & Stockle, ; Qadir et al, ).…”

Agricultural sectors are facing various environmental threats, such as land degradation and water resource depletion. Agricultural water use and cropping patterns are closely linked to each other, with both related to the regional climate. This study evaluated the impacts of future climate and agricultural land-use changes on agricultural water consumption in the Hetao Irrigation District (HID), China. The results show that owing to an increase in temperature and a decrease in precipitation, the future climate in the research area will become warmer and dryer, which will increase the water demand of crops. Future climate in the HID will lead to a 10.5% increase in total irrigation water demand under a scenario of high greenhouse gas emissions and a 6.9% increase under a scenario of low greenhouse gas emissions. Results of the grey prediction modeling indicate that the amount of water allocated to the agricultural sector will decrease, which will make it difficult to meet crop irrigation demands. The results of the gray model also show that the cropping pattern in the HID will vary over time, and the proportion of the area of cash crops will increase by 5.3% during the next decade. Regional agricultural water use can be reduced by adjusting the cropping pattern under irrigation water limitations. Meanwhile, the saved water can be used for soil desalination in cultivated land in the HID.Consequently, adjusting the cropping pattern is a nature-based solution by which to address climate change and guarantee the sustainable use of regional water and land resources.

“…Comparing the source of cultivated land gain, we found that forest land and grassland accounted for 80% of the total area between 2005 and 2010, however, due to the thin arable layer and low soil fertility, the lands gained from forest land and grassland are considered to have poor productivity [37]. Moreover, the land acquired from coastal land often suffers from soil salinization, and so is not suitable for farming [38]. From the spatial distribution, a number of the gained lands were in areas that were remote from rivers and roads, or in mountains with large slopes.…”

Cultivated land in China has faced severe challenges in recent years due to rapid urbanization. In 1997, the "cultivated land requisition-compensation balance" policy was implemented by the government to maintain the quantity and quality of cultivated land. Previous studies mainly focused on the quantity changes of cultivated land. In this study, from a quality perspective, we characterized the occupation and compensation of cultivated land in Wenzhou City utilizing remote sensing and geographic information systems during 2005-2010 and 2010-2014. Our results indicated that although the quantity balance of cultivated land has been achieved in Wenzhou, there was a trend of consuming prime cultivated land for urbanization while compensating with less productive land. It was also found that topography, water resources, and accessibility play important roles in cultivated land changes, with urbanization occurring on the eastern coastal plain where high quality lands are prevalent. Less than 60% of the gained lands were under cultivation, with the majority of reclaimed land from forests and coastal areas and located in remote regions. Therefore, we suggest that a "cultivated land protection red line" policy should be implemented to protect the best cultivated lands, while preventing random land reclamation to secure agricultural and environmental sustainability.

“…Salinized soils are widely distributed in the cold temperate zone, temperate to tropical areas, and are found in Asia, the Americas, Australia, Africa, and other regions (Li, ). Foreign scholars have conducted considerable research on soil salinization with a focus on different aspects of soil science and ecology (Cai, Zhang, Liu, & Zhou, ; Cramer, ; Eldeiry & Garcia, ; Smedema & Shiati, ) at different scales in various regions, involving salt acquisition, dynamic monitoring, the temporal and spatial characteristics of the formation mechanism, measures for forecasting, early warning and remediation, and methods ranging from traditional numerical prediction to depth spatial positioning simulation (Alexakis, Gotsis, & Giakoumakis, ; Bouksila et al, ; Clarke, Bell, Hobbs, & George, ; Harti et al, ; Wichelns, ).…”

An objective requirement of the sustainable utilization of soil resources and agricultural production management is the determination of the status of soil salinization and an understanding of its dynamics. This study selected the coastal plain, the Yellow River flood plain, and key inland areas with salinization in Shandong Province. Sampling and analysis of soil salinization in cultivated lands were conducted in 2015–2016, and 3,551 valid samples were obtained. Statistical and spatial analyses were performed and compared with the data from the Second Soil Survey (1979–1985). The degree, area, distribution, and dynamic characteristics of soil salinization in Shandong Province were analyzed. The results showed that the total salt content of the study area was mainly slight to moderate, and the salinization was dominated by chloride salts. At present, the land area of salinized cultivated land was 384.00 thousand ha, accounting for 11.30% of the total cultivated land area. Soil salinization showed a concentrated distribution along the coastal plain that was scattered in the Yellow River flood plain and inland areas, and the salinity decreased from the coast to the inland area. Compared with the Second Soil Survey period, the salinized cultivated land area had decreased by 431.59 thousand ha, a decrease of 52.9%. The degree of salinization, especially in coastal area, was substantial, and the gravity center moved northeastward. In this study, the characteristics and dynamics of the present state of soil salinization in Shandong Province were examined, providing a scientific basis for the utilization and management of cultivated land resources in saline areas.
