The Alibi of Capital
Stealing the future and concealing the theft - capitalism's method, as examined by the author of the acclaimed Carbon Democracy Today, extraordinary wealth seems to arrive from nowhere. The trick of conjuring this unearned wealth is, in fact, the key to understanding capital­ism's origins and a clue to why the catastrophe of climate collapse is upon us: value is created by consuming the future. The Alibi of Capital explains how this came about through the imperial expansion of the West, en­cumbering today's generations with repayments on earlier extractions. Timothy Mitchell identifies the forms of capitalisation, credit, and coercion that turn prospective assets into present income. Rejecting the common idea that claims on the future create only financial or fictitious capital, he traces the terraforming projects - the destruction of rivers, the colonising of territory, the expan­sion of infrastructure, and the burning of carbon - through which the future has been squandered. Terms such as finance, technology, the economy, and growth function as alibis that conceal this devastating form of extraction.
Using Mineral Chemistry to Characterize Ore-Forming Processes
An ore deposit is an aggregate of minerals that can be economically recoverable and utilized. Ore minerals and gangue minerals are products of ore-forming processes and indicators of ore genesis. The radioisotopes of minerals can provide insights into the ages of mineralization. The stable isotopes of minerals can indicate the nature and origin of ore metals and fluids. The chemical composition of minerals can reflect the original composition and evolution of ore fluids. Combined with the texture, generation, and paragenetic association of minerals, the ore-forming processes can be well constrained. This Special Issue is intended to present mineralogical, geochemical, isotopic, and geochronological studies aiming at constraining the ore-forming processes and mechanisms of various types of mineral deposits. This Special Issue brings together nine studies that employ mineral-based investigations to advance the understanding of ore-forming processes. The contributions demonstrate how integrated approaches combining microtextural analysis, in-situ geochemistry, and isotopic systems can unravel complex mineralization processes across diverse geological settings. These studies successfully trace fluid evolution pathways, constrain metal sources, determine precise mineralization ages, and reveal petrogenetic processes controlling metal endowment. The findings demonstrate how mineral-scale signatures can reveal large-scale geological processes, from crust-mantle interactions in magmatic systems to fluid-rock reactions in hydrothermal environments.
Advanced Multi-GNSS Positioning and Its Applications in Geoscience
Although real-time kinematic positioning (RTK), precise point positioning (PPP), and PPP-RTK have the ability to provide centimeter- or millimeter-level positioning accuracy, they are easily affected by observation environments, resulting in the insufficient positioning stability, continuity, and credibility. As a result of their high equipment costs, it is also difficult to target consumer-level mass users. To further expand the application of multi-GNSSs in geoscience and achieve industrialization, new theories, models, and methods are urgently required. This Special Issue offers insights into the advanced algorithms for multi-GNSS high-precision positioning, multi-sensor integrated data processing, and their applications in geoscience.

Every river looks simple at a distance: a blue line on a map, a brief blur beneath a bridge. Up close, each bend turns out to be crowded with stories of struggle, ingenuity and care. This book walks the length of great waterways alongside paddlers, hydrologists, Indigenous guardians and ferrymen, tracing a layered river history that most atlases ignore. Chapter by chapter, it shows how flood forecasters, levee sceptics and delta pilots quietly changed the way societies understand hydrology and society. Their work reshaped flood maps, dam plans and legal language around rights of rivers, often long before those phrases made headlines. Along the way, readers see how environmental justice rivers campaigns, indigenous water guardians and sharp-eyed river rangers challenge old assumptions about who gets to speak for the water. For readers of narrative environmental non-fiction, policy debates and travel writing, this is a source-to-sea journey through water governance in practice. It brings to life source to sea journeys that connect shrinking glaciers to sinking deltas, and floodplain management decisions to everyday lives on the banks. By the end, you will see your own local channel differently: not as scenery, but as a living system whose future depends on the choices we make about river conservation book priorities and climate change rivers realities today.

Land Use/Land Cover and Natural Hazards
Over the past few decades, the risks associated with natural hazards have increased significantly due to changes in climate as well as land use/land cover (LULC), both of which are mainly driven by anthropic pressure on landscapes, such as urbanization, forest management practices, agricultural practices, and similar processes. Climate and LULC change contribute significantly to variations in the frequency, variability, and magnitude of natural hazards, including floods, landslides, erosion, and others. Constant progress in remote sensing (RS) enables the rapid collection of high-quality and accurate information on landscape characteristics, particularly LULC. Geographic information systems (GIS), in turn, provide tools for processing, modeling, analyzing, and synthesizing spatial data. Together, RS and GIS play an essential role in natural hazards mapping, monitoring, and assessment. Therefore, the focus of this Special Issue was to gather and present current knowledge on the interactions between LULC and natural hazards and to examine the impacts of LULC changes and scenarios on the occurrence of natural hazards, as well as vice versa-the impacts of natural hazards on LULC and society-across various spatial scales, from local to global. Addressing these issues has the potential to support risk managers and decision-makers in adopting appropriate mitigation and adaptation actions, as well as resilient preparedness and response strategies.

Applying Deep Learning Technology for Spatiotemporal Prediction of Air Pollution from Urban Mobile Sources
Mobile source emissions account for more than 80% of carbon monoxide and hydrocarbons and more than 90% of nitrogen oxides and solid particles in urban air pollutants. Also, mobile source emissions have become the main source of urban air pollution, causing serious damage to the social ecological environment. Therefore, it is necessary to study the comprehensive supervision and analysis methods of urban mobile source emissions, which is of great significance for protecting public health and improving rational urban planning as well as traffic conditions. Meanwhile, the temporal and spatial distribution of urban mobile source emissions is affected by many complex factors. On the one hand, from the perspective of long-term vehicle emission inventory calculation, it mainly depends on the city's total vehicle volume and vehicle type composition. On the other hand, in terms of short-term and real-time variation in traffic emissions, it is mainly influenced by urban road network topology, traffic flow conditions, and external meteorological factors. This series of factors has led to great challenges in achieving full-time monitoring and comprehensive supervision of urban mobile source emissions. By summarizing the existing literature, we find that the focus of mobile source emissions prediction tends to shift from the road segment level to urban region scale, from a single city to cross cities, and from macro inventory prediction to fine-grained instantaneous prediction.

Wave Loads on Offshore Structure
The ocean is rich in resources, such as oil, gas, wave power, and wind power. The development of these resources heavily relies on different types of offshore structures, including various platforms and fixed or floating structures. In addition, the development of coastal cities also demands the construction of more sea-crossing transportation structures, including underwater tunnels, sea bridges and breakwaters. These offshore structures face challenges in the complex ocean environment, where the impact of waves and currents remains a primary factor leading to structural damage. Despite numerous studies on wave and current loads, the field still presents many unresolved issues and remains one of the most important topics in ocean engineering. Further research would deepen our understanding of hydrodynamic loads, enabling better guidance for engineering applications and enhancing the safety design and operation of offshore structures.Thus, this Special Issue aims to highlight recent advances in wave and current loads on offshore structures, the dynamics of these structures under such loads, and the corresponding vibration mitigation methods.

Climate Change and Hydrological Processes
Water is one of the essential elements sustaining human life and security. In recent years, the emergence and intensification of extreme climatic events have increasingly compromised water availability and quality, profoundly affecting people's well-being. Periods of drought have intensified water scarcity, while, conversely, rainfall has become more intense and frequent in various regions around the world. Within this evolving climatic context, the need to evaluate, forecast, and mitigate the occurrence and effects of extreme events has become a pressing priority-not only as a subject of scientific investigation but also as a matter of great importance for policymakers and decision-makers seeking to prevent or reduce their inherent impacts. Therefore, this reprint focuses on a range of interrelated topics, including the influence of climate change on water runoff processes, the projection of flash-flood susceptibility under different climate scenarios, and the variability of maximum river discharges in response to changing climatic conditions. It also addresses the impacts of climate change on the frequency and severity of droughts, the challenges of assessing risk and uncertainty in detecting drought events, and the need for both quantitative and qualitative analyses of extreme hydrological occurrences. Furthermore, it emphasizes the importance of evaluating hazards and risks in drought assessment, integrating environmental economics into flood and drought risk management, and modeling the complex relationships between climatic variables and hydrological processes.

Feature Papers for Land Systems and Global Change Section
This Reprint presents a concise selection of recent studies that deepen our understanding of land system dynamics under accelerating global change. Land systems arise from interactions among ecological processes, human activities, and socio-economic structures, and their evolution is increasingly shaped by multiple, intertwined pressures. The contributions highlight how climate variability, urban growth, institutional change, and ecological degradation jointly drive land transformation, often producing nonlinear and spatially heterogeneous outcomes. Several studies investigate how land use transitions alter ecosystem functions such as soil stability, hydrological regulation, and cultural benefits. Case analyses from diverse regions show that landscape patterns and ecological resilience respond differently across environmental and developmental contexts, emphasizing the need for locally tailored strategies. Urban environments feature prominently, with research assessing ecological efficiency, green infrastructure, and the impacts of rapid urbanization on environmental stress. These findings demonstrate the dual role of cities as both drivers of land system change and critical arenas for nature-based solutions. Other contributions address governance and conceptual challenges, including land resource equity and the need for coherent planning frameworks.
