“…Additionally, the ecological projects in TP aimed at improving ecological conditions, such as those implemented over forests and grassland (Hua, Zhao, & Pereira, 2022 ), could also enhance the precipitation contribution through both direct (increased ET) and indirect mechanisms (land‐atmosphere interaction). There has been ample evidence suggesting that ecological projects improved vegetation and intensified ET (Chen et al, 2022 ; Yu et al, 2020 ; Zheng et al, 2022 ). Some even argued that ecological restoration may risk water resources in TP through increased ET (Xiao et al, 2021 ).…”

The ecosystems of the Tibetan Plateau (TP) provide multiple important ecosystem services that benefit both local populations and those beyond, such as through climate regulation services on precipitation for East Asia and China. However, the precipitation regulation service of the TP ecosystems for supplying moisture and maintaining precipitation is yet to be evaluated. In this study, we used the moisture recycling framework and a moisture tracking model to quantify the precipitation regulation services of TP ecosystems for their contribution to precipitation. We found TP ecosystems contributed substantially to local and downwind precipitation, with a contribution of 221 mm/year for the TP and neighboring areas through evapotranspiration (ET) (104 mm/year through transpiration), declined to <10 mm/year for eastern China and other surrounding countries. Among ecosystem types, grassland contributed most to precipitation, followed by barren and snow lands, forests, and shrublands. In terms of seasonality, precipitation contribution from TP ecosystems was greater in summer months than in non‐summer months for western China, while the opposite was true for eastern China—although the magnitude was much smaller. Over the past two decades, the significant ET increases in TP translated to a widespread increase in precipitation contribution for TP and downwind beneficiary regions from 2000 to 2020. Our study provides a quantitative way to understand the precipitation regulation services of TP ecosystems through moisture recycling, substantiating their key role to maintain precipitation and the water cycle for downwind regions—effectively acting as an ecological safeguard that could be perceived by the public.

“…Oases are the most dynamic, productive, and vulnerable ecosystems in drylands and are centers of human life and economic development in arid and semi‐arid regions (X. Li et al., 2016; S. Zhou et al., 2015). In China, oases support the livelihoods of tens of millions of inhabitants, and maintaining the stability of oasis ecosystems is essential for regional ecological security and sustainable development (P. Chen et al., 2022a). Under climate change and expanded human activity, China's oases have undergone a significant expansion during the past three decades (P. Chen et al., 2022a), which has profoundly affected regional water budgets and ecosystem services (Pan et al., 2021; Wei et al., 2018; Zeng et al., 2019).…”

Implementation of a multi‐layered land degradation monitoring and forecasting framework toward integrated countermeasure planning in drylands

Various earth observation (EO) data and related spatial technologies are employed to monitor land degradation (LD) and its impacts on the drylands. However, a comprehensive framework that integrates multiple data sources and metrics to generate a consistent output still needs to be explored. Furthermore, the lack of consistency and the limited reliabilities of existing approaches make it challenging to identify proper countermeasures (avoid, reduce, reverse LD) and support decisions to combat LD in line with the Land Degradation Neutrality (LDN) Framework. The “Multi‐Layered Land Degradation Tracer (ML‐LDT)” is a framework that addresses the above research gaps. It is based on a comprehensive framework that integrates data extraction, LD monitoring, and forecasting capacities and consists of three functional layers, that is, a base data processor, monitoring/modeling components, and a forecasting layer employing machine learning (ML) algorithms. ML‐LDT has a state‐of‐art capacity to model wind erosion together with sand and dust storms (SDS), making it particularly suited to the arid lands most prone to these processes. It is implemented over cloud processors with open‐source components based on industry standards. Therefore, the routines are easily adaptable to user requirements in LDN planning. We evaluated the ML‐LDT framework in the Indian Thar Desert and Inner Mongolian drylands. The results showed the overall robustness of the procedures and that ML‐based models provide good insights to forecast future LD/SDS patterns that can be used to simulate LDN scenarios and targets. We validated the forecasting results against LD maps and remote sensing observations.
