As part of the joint research conducted by Japan and China on the agricultural development of the Mu Us Shamo Desert, surveys on soil physical properties, moisture consumption, and the irrigation effect have been carried out on several plants in the fields of the Mu US Shamo Research Center since 1985. Using these results, schedules were established for the irrigation of a pilot farm which was constructed at the Research Center in 1991. The irrigation schedules were mainly based on the design guidelines of the Ministry of Agriculture, Forestry and Fisheries of Japan. As a result, the dimensions for the irrigation interval and water quantity per irrigation unit were estimated under the various plants in the pilot farm. From these design dimensions and the daily rainfall measured during the past 27 years, the net water requirement was estimated considering the effective rainfall. Also, the characteristics of the irrigation and rainfall could be explained by discussing the ratio of the total net water requirement to the total evapotranspiration, which subsequently indicates the factors in the pilot farm's future water management. Finally, in order to prevent the salinization of soils and groundwater and to select suitable irrigation methods, some recommendations are given for better use of technology in conservation management for the pilot farm.

The security of food-energy-water (FEW) systems is an issue of global concern, especially in mega-urban regions (MURs) with high-density populations, industries and carbon emissions. To better understand the hidden links between urbanization and FEW systems, the pressure on FEW systems was quantified in a typical rapidly urbanizing region—the Bohai MUR. The correlations between urbanization indicators and the pressure on FEW systems were analyzed and the mechanism of the impact of urbanization on FEW systems was further investigated. The results showed that approximately 23% of cropland was lost, 61% of which was lost via conversion to construction land and urban areas expanded by 132.2% in the Bohai MUR during 1980–2015. The pressure on FEW systems showed an upward trend, with the stress index of the pressure on FEW systems (FEW_SI) ranging from 80.49% to 134.82%. The dominant pressure consisting of that has converted from water system pressure to energy system pressure since 2004. The FEW_SI in the Bohai MUR was enhanced with cropland loss and increases in urbanization indicators. Additionally, land use, populations, incomes, policies and innovation are the main ways that urbanization affects FEW systems in MURs. This study enhances our understanding of the variation in pressure on FEW systems in MURs and the effects of urbanization on FEW systems, which will help stakeholders to enhance the resilience of FEW systems and promote sustainable regional development.

This study employed the Surface Energy Balance System (SEBS) algorithm to determine the actual evapotranspiration (ET) trends of the piedmont plain region of the Golmud River Basin between 2001 and 2016 and the effects of climate change and human activities on ET. The results indicate that the regional ET increased in the study area from 2001 to 2016. However, ET trends exhibited no change in most parts (68.58%) of the study area over the 16 years, but increased significantly in saline ponds and areas with vegetation cover, whereas no significant trends were observed in saline marshes or the piedmont Gobi gravel plain. The ET trend was closely related to the land-cover changes caused by human activities in the Golmud River Basin. During the study period, saline pond areas expanded from 50.57 to 257.85 km2 due to potash fertilizer production, and the area of farmland increased from 28.71 to 62.91 km2 and these changes contributed greatly to ET changes. Also, groundwater exploitation for potash fertilizer production and irrigation were correlated with ET.
