How do multidimensional land use conflicts shape rural multifunctionality? An empirical study of the Yangtze River Delta from a conflict–coordination perspective

In the context of urban–rural integration, how multidimensional land use conflict (LUC) differentially shapes rural multifunctionality is a key question for sustainable rural development. Existing studies, however, have largely treated the two independently, with limited systemat...

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poo...

Asymmetric bloom lengthening drives high-latitude ocean chlorophyll accumulation imbalance

Terrestrial ecosystems maintain a stable time-allocation budget between growth and senescence, but whether this applies to the ocean remains unclear. Using fused satellite LiDAR and ocean-color data (2007–2022), we show that marine phenology is variable and asymmetric. In high la...

Wildfires diminish vegetation control on surface runoff

Wildfires are increasingly reshaping global terrestrial ecosystems, yet their impacts on the fundamental coupling between vegetation and the hydrological cycle remain poorly understood. Here, we present a global-scale assessment of how wildfire disturbances alter the sensitivity...

Spaceborne multi-sensor tracking reveals hydrologic decoupling during the record-breaking Sahara flood

Satellite remote sensing enables large-scale quantification of extreme hydrologic events in data-scarce regions, yet the integration of multi-sensor observations to resolve hydrologic responses remains limited. The record-breaking 2024 Sahara flood presents a unique opportunity t...

Composting rural kitchen waste for nutrient recovery and runoff pollution mitigation: a Bayesian modeling approach

In China’s ecologically sensitive Erhai Basin, open-dumped rural kitchen waste causes both nutrient loss and water quality degradation. Here we integrate household surveys, on-site composting experiments, and a Bayesian dual-pool wash-off model in a pilot case study of six villag...

Climate change and extreme hydroclimatic events primarily regulate sedimentary organic carbon sequestration in an alpine lake on the Tibetan Plateau

Long-term carbon sequestration dynamics of alpine lakes on the Tibetan Plateau under dual pressures from ongoing climate warming and frequent climatic extremes remain poorly understood. Here, we reconstructed century-scale organic carbon burial dynamics and identified organic car...

Nitrogen–Phosphorus Pollution Dynamics and Export Processes of Anthropogenic Polders in the Middle–Lower Yangtze River: A Regional Review

Polders are typical semi-artificial and human-dominated ecosystems widely distributed in the middle and lower reaches of the Yangtze River Basin. They serve as important sinks and sources of nitrogen (N) and phosphorus (P) in agricultural watersheds. Long-term intensive human int...

Tracing the spatiotemporal diffusion of cross-strait Mazu culture: a knowledge graph-driven analysis

Mazu culture constitutes a transregional system of religious heritage characterised by ritual practices and institutional networks spanning coastal China, Taiwan, and overseas Chinese communities. Although previous studies have described its historical development and local adapt...

Seasonal wet–dry transitions reveal contrasting microbial stability and nutrient cycling across floodplain lake habitats

Abstract Saucer-shaped sub-lakes in floodplains undergo strong seasonal changes in water level and connectivity, but their microbial responses and roles in nutrient cycling remain poorly understood. Here we show, using 28 lake units across Lake Poyang, China, that seasonal hydrol...

Lakeshore transformation and water color dynamics: A satellite-based 23-year assessment of nine plateau lakes in Yunnan, China

Study region Nine plateau lakes in Yunnan, China. Study focus We developed an extended lakeshore utilization classification framework to categorize lakeshores as natural, agricultural, or artificial using fixed maximum shorelines. We then derived the Forel–Ule Index (FUI) of the...

How Much Water Can Be Seasonally Buffered by China's Largest Floodplain Lake? A Refined Estimate From SWOT

Abstract Poyang Lake, China's largest floodplain lake, plays a crucial role in regional hydrology by seasonally regulating water to mitigate floods and sustain extensive wetland ecosystems. However, complex hydrodynamics and significant spatial hydraulic gradients often invalidat...

Does the supply of eco-assets match the demand for eco-products spatially? A case study of the Yangtze River Delta urban agglomeration

The value realization of eco-assets through eco-product consumption requires both a sufficient ecological supply base and enabling demand-side conditions. Yet assessments in economically developed regions often focus on supply alone. A supply-only assessment can hide the spatial...

Has hydrological alteration driven ecosystem service risks in large floodplain lakes? A novel framework for spatiotemporal assessment and hydrological thresholds identification

Study region Poyang Lake, China’s largest freshwater lake, is a critical ecological hub. Study focus Hydrological alteration strongly affects floodplain ecosystem services (ES), yet their spatiotemporal risks and hydrological controls remain poorly understood. We developed an int...

Spatial distribution of soil macronutrients and nutrient index for sustainable agriculture in the Khulna region of Bangladesh

Abstract Purpose Evaluation of soil fertility is essential for sustainable agriculture; yet studies on nutrient distribution indices, particularly in Bangladesh, remain limited despite increasing research. The purpose of this study is to identify nutrient indices and create spati...

Three Gorges Dam-driven redistribution, sediment-water partitioning, and health risks of heavy metals in the Yangtze River

The Three Gorges Dam (TGD), the largest hydraulic project on the Yangtze River mainstream, has altered hydrodynamic regimes and sediment transport. However, how its interplay with basin-scale pollution control policies regulates heavy metal behavior remains poorly understood. The...

Runoff Simulation and Analysis in the Upper Yellow River Basin Using a Budyko–XGBoost Coupled Model

The Upper Yellow River (UYR) basin is the predominant runoff-yielding area of the entire watershed. Accurately simulating annual runoff is crucial for water resources management. While the Budyko framework effectively captures long-term hydro-thermal equilibrium, it struggles to...

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited d...

Engineering and land use intensified climate-driven Yangtze River flood hazards since the Little Ice Age

Understanding the interplay between climate variability and human activities is essential for assessing long-term river flood hazards. Yet, the relative contributions of natural and anthropogenic drivers to flood magnitude remain poorly constrained due to limited multicentury rec...
