Coal Geology & Exploration
Objective Deep coal mining areas in regions such as Inner Mongolia, Shaanxi, Shandong, and Gansu in China feature intricate hydrogeological conditions, which lead to substantial water drainage from roofs and increasingly prominent rock bursts induced by water drainage in overburden confined aquifers. This study investigated the evolutionary patterns of the stress field in coal seams during the water drainage of overburden confined aquifers. Methods By combining the laboratory charge induction experiments of coals under graded loading with charge monitoring pre- and post-water drainage from a roof in a coal mine, this study systematically examined the variations of induced charge in …

Coal Geology & Exploration
Objective High stress with superimposed weak dynamic disturbance serves as a critical factor including rock bursts. However, the microcrack propagation characteristics and energy dissipation pattern of rocks under different disturbance amplitude, frequencies, and unloading ranges remain unclear, leading to a lack of technical support for rock burst prevention and control.Methods Based on the true triaxial unloading dynamic disturbance tests, this study analyzed the instability failure patterns of deep surrounding rocks under different disturbance amplitude (5, 10 MPa), frequencies (4, 10 Hz), and triaxial stress unloading (0, 12 MPa). Moreover, this study examined the characteristics of microcracks in rocks using …

Coal Geology & Exploration
Significance As the new round of national exploration & development planning continues, resource exploration is advancing toward the deep Earth. However, deep strata exhibit diverse rock types, which complicate the measurement of rock mechanical parameters. Furthermore, the harsh environments of these strata, characterized by high temperatures, high pressures, and high in-situ stress, are prone to induce downhole accidents like drilling tool failure, wellbore collapse, loss of circulation, and well kicks, posing challenges to geological drilling. Advances Aiming at the perception and modeling of complex geological environments, this study reviews the existing studies on the modeling of stratigraphic characteristic parameters from …

Modern Governance System For Global Sustainable Development Goals, Bojie Fu, Jinghai Li, Junze Zhang
Bulletin of Chinese Academy of Sciences (Chinese Version)
The Sustainable Development Goals (SDGs), as a key global framework for addressing social, economic, and environmental challenges, have drawn widespread attention due to the slow progress in their implementation. Despite the international community’s high regard for the SDGs, current research predominantly focuses on the assessment of progress and the analysis of interlinkages among the goals, with insufficient discussion on how to improve governance systems aimed at achieving the SDGs. Based on the system classification framework of SDGs, which includes “essential needs”, “objectives,” and “governance” categories, this study develops a governance system for the comprehensive realization of the SDGs. It analyzes …

Upholding “Triple Real” Vision For Ocean Negative Carbon Emissions To Advance Global Climate Governance, Nianzhi Jiao, Chuanlun Zhang, Tingwei Luo, Jihua Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Addressing climate change is a formidable challenge for humanity, and achieving the temperature control goals of the Paris Agreement cannot rely solely on greenhouse gas emission reductions—negative emissions are an inevitable solution. The ocean, as the planet’s largest active carbon reservoir, holds immense potential for negative emissions, yet there is no internationally recognized pathway to realize it. The UNESCO-IOC international program of Ocean Negative Carbon Emissions (ONCE) builds on the original theory of the microbial carbon pump (MCP) and integrates known ocean carbon sequestration mechanisms BCMS (standing for biological carbon pump, carbonate counter pump, MCP, solubility carbon pump) to propose …

Bulletin of Chinese Academy of Sciences (Chinese Version)
Against the backdrop of methane emission control becoming a hot spot in global climate governance, China, as a major methane emitter, has committed to announcing its 2035 Nationally Determined Contributions covering all greenhouse gases before COP30, drawing significant attention from the world. In order to systematically analyze the international dynamics and China’s response strategies in methane emission control, this article explains the necessity and urgency of methane mitigation based on the current situation of global methane emission, and also clarifies essential meaning of international game to reveal China’s challenge and opportunity amid the backlash against globalization. Besides, it sorts out …

Bulletin of Chinese Academy of Sciences (Chinese Version)
As a foundational pillar of an increasingly digital and intelligent society, computing infrastructure embodies a dual nature—marked by high energy consumption and potential for emission reduction simultaneously. This duality positions it as a critical domain requiring balance under China’s dual-carbon goals. Nevertheless, there remains no clear consensus on methods for estimating its carbon emissions. Its ambiguity stems from differences in the applicability of assessment methods across various lifecycle stages, as well as a fragmented understanding of its intrinsic emissions and enabling effects on carbon mitigation. This study systematically reviews estimation methodologies from both broad and narrow perspectives, highlighting the heterogeneity …

Inter-Provincial Spatial Coupling Of Paddy Fields In China Has Accelerated The Water Consumption, Wenguang Chen, Wencai Zhang, Ming Lei, Ruqian Zhang, Zhenting Zhao, Enyi Xie, Jing Zhao, Xiangbin Kong
I-GUIDE Forum
Rice trade has played a significant role in ensuring global rice consumption security. However, the spatial coupling of paddy fields based on rice trade can also transfer ecological environmental effects and threaten the sustainability of local systems. As the largest rice producer and consumer in the world, as well as one of the countries with the lowest per capita water resources, studying the inter-provincial rice flow in China and its water resource utilization efficiency is of great significance for ensuring national rice security and water resource security. Research has found that, China's rice consumption decreased by 11.97 Mt from 2000 …

Anthropogenic Impacts On Aquatic Organisms, Alexis Khursigara
Sustainability Seminar Series
Aquatic environments are often dynamic, experiencing shifts in a multitude of anthropogenic stressors related to climate change and contaminant loads. Aquatic organisms, such as fish and invertebrates, must cope with these changes that can be rapid or gradual, acute or chronic, and often co-occurring. Understanding how well aquatic organisms tolerate these shifts is imperative for management practices. In this presentation, Dr. Khursigara will discuss how different anthropogenic stressors alter the physiology and behavior of multiple fish and aquatic invertebrate species.

Climate change, loss of plant biodiversity, and ocean pollution signal the drastic changes in our ecology that call us to attend to the needs of more than human forms of life on Earth. Sustainable design and HCI research are responding to this call by offering methods and approaches to design more sustainable products and systems and recently, more than human design is building momentum. This agenda seeks to reform traditional design processes by decentering the creative agency of the dominant socio-economical group of humans and foregrounding those of diverse Others. In this paper, I focus on plants as a nonhuman …

Using Catholic Social Thought And The Normativity Of The Future In Responding To The Super Wicked Problem Of Climate Change, Stephanie Ann Yu Puen
Theology Department Faculty Publications
The climate crisis has been dubbed a “super wicked problem”—one where there is a sense of urgency, complicity in the problem by those who wish to solve it, and difficulty in sacrificing the short term for the long term. To respond to the difficulty of long-term thinking in addressing super wicked problems as part of SDG 13 (Climate Action), there is a need to pay attention to the narratives, norms, and values at work, and how we employ these categories in climate action. This paper discusses how Catholic social thought and the concept of the normativity of the future can …
