Abstract Large‐scale ecological restoration (ER) in semiarid regions is often associated with substantial terrestrial water storage (TWS) depletion. This study challenged previous estimates by demonstrating the critical importance of considering other human activities when assessing ER impacts on TWS. Using a novel analytical framework integrating GRACE satellite data and ground observations, we analyzed TWS changes China's Mu Us Sandyland under two scenarios: without mining farming activities. Our results show that consumed at an average rate 11.7 ± 12.2 mm yr −1 from 2003 to 2022. Neglecting led 251% overestimation ER's effect provided more nuanced understanding resource dynamics restored ecosystems, emphasizing need for comprehensive approaches assessments informing sustainable land management strategies globally.

Rivers originating in the Tibetan Plateau are crucial to population Asia. However, research about quantifying seasonal catchment memory of these rivers is still limited. Here, we propose a model able accurately estimate terrestrial water storage change (TWSC), and characterize processes durations using curve influence/domination time, respectively. By investigating eight representative basins region, find that precipitation-dominated mainly controlled by precipitation, non-precipitation-dominated strongly influenced temperature. We further uncover basins, longer influence time corresponds domination with approximately six/four months during monsoon season. In addition, long-term observed basins. Quantifying can identify efficient lead times for streamflow forecasts resource management.

Short instrumental streamflow records in the South and East Tibetan Plateau (SETP) limit understanding of full range long-term variability streamflow, which could greatly impact freshwater resources for about one billion people downstream. Here we reconstruct eight centuries (1200-2012 C.E.) annual from Monsoon Asia Drought Atlas five headwater regions across SETP. We find two regional patterns, including northern (Yellow, Yangtze, Lancang-Mekong) southern (Nu-Salween Yarlung Zangbo-Brahmaputra) SETP showing ten contrasting wet dry periods, with a dividing line moisture regimes at ~32°-33°N identified. demonstrate strong temporal nonstationarity variability, reveal much greater high/low mean flow periods terms duration magnitude: mostly pre-instrumental wetter conditions Zangbo-Brahmaputra drier other rivers. By contrast, frequency extreme flows during Nu-Salween, has increased by ~18% relative to periods.

Agriculture is considered a significant climate change (CC) driver due to greenhouse gas (GHG) emissions and the loss of fertilizers that contribute water eutrophication. On other hand, effects are already impacting agriculture, endangering food security. This paper explores dichotomies agriculture on CC as well focusing contribution nanofertilizers can bring this complex system in both directions. The strategies reduce while adapting mitigating its must be global effort. It not possible focus only reduction GHG stop being felt worldwide. Nanofertilizers, especially slow- controlled-release nanofertilizers, nutrient input also boost productivity some effects, such soil imbalance agricultural emissions.

Abstract GRACE (Gravity Recovery and Climate Experiment) has been widely used to evaluate terrestrial water storage (TWS) groundwater (GWS). However, the coarse‐resolution of data limited ability identify local vulnerabilities in changes associated with climatic anthropogenic stressors. This study employs high‐resolution (1 km 2 ) generated through machine learning (ML) based statistical downscaling illuminate TWS GWS dynamics across twenty sub‐regions Indus Basin. Monthly anomalies obtained from a geographically weighted random forest (RF gw model maintained good consistency original at 25 grid scale.

Abstract. Accurate long-term daily cloud-gap-filled fractional snow cover products are essential for climate change and hydrological studies in the Asian Water Tower (AWT) region, but existing Moderate Resolution Imaging Spectroradiometer (MODIS) not sufficient.
