“…Generally, the area of an oasis is highly correlated with the amount of runoff from the mountainous areas in both the Tarim Basin and in other nearby areas 12–16 . With the development and utilization of water resources in the Tarim Basin, especially the enlargement of agriculture, the oases begin to diminish in the downstream areas and then disappear because of the shortage of water, which finally results in a spatial pattern in which oases are mainly in the upstream areas 4,17,18 , as shown in Fig.…”

The spatial evolution of the oasis cold-wet effects in Tarim Basin, northwestern China, are explored quantitatively by using the China Meteorological Forcing Dataset, with spatial and temporal resolution of 0.1 degree and 3 hours, respectively, and the hydrological interactions between the oases and water vapor transfer are discussed to uncover the influence of oases on regional precipitation. The results reveal that the annual precipitation exhibits an increasing trend from desert toward oasis at all four oases. However, the cold effect is not the dominating factor increasing precipitation, since the maximum increasing rate of precipitation is accompanied by the minimum decreasing rate of temperature. Indeed, water vapor transportation is more important than the cold effect. The maximum promotion of precipitation is observed in western basin, where the water vapor transfer follows the gradients of decreasing temperature and increasing humidity. Conversely, the minimum promotion in southwestern basin results from water vapor transportation following the temperature increasing. Therefore, the transfer of water vapor and its interactions with local surface conditions determine the precipitation in oasis areas. Understanding these processes is crucial to exploring the formation and spatial layout of oases, which is helpful for preventing desertification and protecting the fragile oasis ecosystem.

“…This, in turn, would have significant implications for achieving land degradation neutrality or reversing the increasing trend of land degradation in China. Even before the adoption of Sustainable Development Goal 15.3 in September 2015, which provides that " By 2030, combat desertification, restore degraded land and soil affected by desertification, drought and floods, and strive to achieve a land degradation world", China has already set a target for restoring a total of one million km 2 degraded land by 2050, to be undertaken in three phases (Wang et al, 2012).…”

“…A total of 2.61 million km 2 of desertified lands caused by wind erosion, water erosion, salinization or freeze-thaw erosion cover approximately 27.2% of the country's entire landmass and spread into 528 counties in 18 provinces (State Forestry Administration of China, 2015). About 400 million residents are being adversely affected by desertification, resulting in a considerable number of environmental refugees and disaster migrants in severely affected areas (Wang et al, 2012). However, only a few studies have been conducted on economic assessment of various impacts of desertification in China (Cheng et al, 2013a).…”

Estimation of the Costs of Desertification in China: A Critical Review

A preliminary conceptual framework is proposed for the estimation of the costs of desertification. This framework consists of assessment of the extent and severity of desertification, identification of various impacts, and valuation of the direct and indirect costs of desertification. Based on this framework, three well cited studies of the costs of desertification in China were critically reviewed. Limitations in these studies include double counting, confusion of short-term and long-term costs, and the lack of necessary adjustment of price parameters. Refinement of the estimates indicates that these limitations have caused serious overestimation or underestimation of the costs of desertification. To achieve more reliable and useful estimates, future studies need to overcome the above limitations and use the latest available data on desertification and its various impacts. A more comprehensive conceptual framework that includes the valuation of dryland ecosystem services could also be developed to guide future studies.

“…The water crisis has changed a lot of arable farming land into desert; this is coupled with neglected farming practices, overgrazing, and the effects of climate change. According to the officials of the Chinese forestry administration, around 1.05 million square miles of the Chinese landmass has undergone desertification; this affects more than 400 million people [22]. Pollution and desertification are reducing China's capacity to maintain industrial production, as well as to yield food and clean water to feed its large population.…”

This study presents a critical analysis of the environmental challenges regarding global environmental policies and current practices in China. The study provides imperative evidence about the current emission control strategies, environmental planning, legislation, policy instruments, and measures to provide a sustainable environment for the present and future generations. The study followed a well-defined analytical methodology to analyse the measures adopted to control emissions as a trade-balancing tool for the environment. The findings indicated that domestic as well as the international collaborations were effective in controlling the present problem of environmental pollution, and suggested a need for collaborative agreements to amend the Environmental Protection Law (EPL). The analytical findings determined that the proposed EPL considered SO 2 or NO 2 emissions while neglecting an important source of environmental pollution, i.e., CO 2 emissions. The research findings also suggested a need for to accelerate efforts in a more professional, practical, and result-oriented manner to analyse the diverse nature of environmental issues. The research highlighted some of the obstacles to the successful implementation of EPL for current and future environmental challenges.
