The results from 334 Chinese cities demonstrate the differences in inequality between developed and developing cities. When individuals share resources within 15-minute accessibility distance, inequality is lower in developed cities relative to developing cities due to more spatially balanced resources, with a decreasing trend over the past 31 years. However, due to the uneven spatial distribution of the population in developed cities, inequality among individuals has increased when resources are divided within 15-minute accessibility distance.

This study bridged the gap by exploring the interactions between urbanization, ecosystem services (ESs), and basic water, energy, and food (WEF) needs within the SJS framework across China and its provinces. By quantifying the minimum and actual demands for freshwater withdrawal, carbon emissions, phosphorus emissions, and land use, as well as the supply of ESs into unified biophysical indicators, we found that: (1) China can meet the basic WEF needs for all from 2000 to 2020, but only water and land provisioning ESs can operate within the SJS. Carbon emissions surpassed the sequestration capacity in 2010, while phosphorus purification ES has consistently been unsafe. (2) The SJS performance in terms of ecological and social fulfilment exhibited scale differences and undergone changes with urbanization. Overall, no province in China can consistently operate within all SJSs. (3) In the process of urbanization, improvements in ecological protection and production practices in most provinces expanded the size of SJS, but the continuous increase in total demand failed to steer regions toward safer spaces.

Using a data-parsimonious biophysical framework with a function of crop growth and water-demanding dynamics, we estimate the additional net economic benefit of irrigated agriculture relative to rainfed conditions for three major crops at the county level. Our results reveal that mean irrigation water values were 0.27, 0.32, and 0.16 USD m<sup>–3</sup> for cotton, maize, and wheat, respectively, which were 2.0 − 3.2 times higher than global estimates. The value of irrigation water significantly increased over time, primarily driven by rising crop prices and improved water use efficiency. Our findings indicate that farmers in arid regions with water limitations may favor crops with high irrigation water use efficiency. Wheat is suggested to be spatially reallocated in light of the economic benefit, given its relatively low output price and water use efficiency. Irrigation water value was more sensitive to precipitation than air temperature by lowering crop prices and narrowing the gap between rain-fed and irrigated yields.

In this study, we integrated the dynamic crop model Noah-MP-Crop with the Weather Research and Forecasting (WRF) model to investigate the biogeophysical climate regulation of temperate forests and its buffering effects on crop yields in adjacent agricultural lands across Northeast China. Our findings revealed that temperate forest barriers induced significant local climate effects by cooling air and surface temperatures and reducing wind speeds within forested areas during the growing season, while also regulating non-local climate, particularly by altering regional precipitation patterns, 2 m water vapor mixing ratio (Q2), and soil moisture, predominantly in adjacent cropland areas. Furthermore, these forest barriers were found to modulate climate extremes, through affecting maximum temperature and wind speed on a local scale, as well as both maximum and minimum Q2 in non-local croplands. Our study also observed that temperate forest barriers, through biogeophysical climate regulation, enhanced GPP, NPP, and grain yields across most cropland areas. This productivity boost was especially pronounced, with yield increases up to 20 % in certain regions during the extreme drought conditions of 2017, underscoring the critical role of temperate forest barriers in sustaining and enhancing crop yields under severe climatic stress.

We analyzed the spatiotemporal pattern of DSTR and its trend under climate change at four scales (global, hemispheric, national, and provincial), with the following main results: (1) DSTR was scale dependent, provincial pattern of which were mainly related to sensible and latent heat fluxes.
