Carbon allowances constitute a foundational component of national carbon emission control frameworks, as they govern the equitable distribution of subsequent allocations and directly shape the overall effectiveness of greenhouse gas mitigation strategies. However, the temporal evolution of carbon allowances is inherently complex, high-dimensional, and nonlinear, thereby posing substantial challen…

IntroductionWeather classification plays a crucial role in applications such as environmental monitoring, disaster management, and smart city infrastructure. Accurate and efficient classification of weather conditions from images remains a challenging task due to variations in illumination, texture, and atmospheric conditions.MethodsThis study proposes an efficient deep learning framework for mul…

The valorization of fishery-derived wastes through microalgal biotechnology provides a practical route to integrate wastewater remediation with high-value bioproduct generation. This study demonstrates an integrated process in which solid fish waste was converted into an algal growth medium via sulfuric acid hydrolysis (3% H2SO4; 1:8, w/v) combined with autoclave-assisted pretreatment (121 °C, 20…

This study examines environmental criticism as a contemporary analytical approach and explores its relationship with environmental law. It adopts a comparative analytical framework to assess the extent of convergence and divergence between ecocritical principles and legal rules governing environmental protection. The study identifies key elements of environmental criticism and traces their presen…

Phytoremediation of areas polluted by heavy metals and toxic metalloids is challenging, particularly in arid regions where limited water availability compromises plant establishment. This study shows that several Atriplex species (A. halimus, A. canescens, A. nummularia, A. atacamensis, A. hortensis, etc.) can be used in a phytostabilization and/or phytoextraction strategy. Many of these species …

IntroductionCoastal wetlands provide critical ecosystem services but face increasing threats from human activities. Although ecological compensation mechanisms are globally recognized, research on tourist willingness-to-pay (WTP) for wetland conservation remains limited, particularly in developing countries. This study investigates this gap using the Red Beach Wetland in China, an internationally…

In the dual context of trade liberalization and the low-carbon transition, understanding how import competition shapes corporate carbon emissions has become a critical question. This study introduces an innovative “dual-track competition” framework and uses panel data of Chinese listed companies from 2010 to 2023 to examine the impact of import competition on corporate carbon emissions, yielding …

A rising human impact alters landscape patterns and determines the agriculture–ecology–economy nexus (AEEN), which further threatens the sustainability of social–ecological system (SES). However, the mechanisms through which policy interventions drive AEEN evolution and regime shifts are not sufficiently elucidated. We adopted the Fujian Province, which is undergoing intensive policy intervention…

Against the global backdrop of accelerating climate change and the urgent need for energy transition, understanding the role of protected areas in shaping renewable energy consumption has become increasingly important. Using panel data covering more than 150 countries worldwide from 2013 to 2022, this study examines the extent to which protected areas shape national renewable energy consumption p…

On 8 April 2024, a total solar eclipse affected the eastern United States, creating a natural experiment to examine short-term atmospheric responses to an abrupt reduction in solar radiation. We collected observations at the Howard University Beltsville Research Campus (HUBC; 39.05° N, 76.88° W), where ground-based and upper-air measurements captured pre-, during-, and post-eclipse conditions und…

IntroductionHigh penetration of renewable energy sources increases operational variability and planning uncertainty in smart grids. Transparent prioritization of technologies is required before detailed sizing and dispatch analysis.MethodsA decision support framework based on expert weighted Technique for Order Preference by Similarity to Ideal Solution is applied. Four alternatives, solar PV, wi…

This study investigates the intensity of Land Surface Temperature (LST) and the Urban Heat Island (UHI) effect across Lahore District and its surrounding urban and peri-urban areas. Landsat satellite data were utilized to examine the spatiotemporal patterns of LST, identify UHI zones, and assess changes in land use and land cover (LULC), the Normalized Difference Built-up Index (NDBI), the Normal…

Current theories of saturation-excess and infiltration-excess runoff fail to comprehensively and accurately elucidate the intricate runoff generation process in the Loess Plateau. It is imperative to examine the impact of preferred flow and plug flow on river runoff dynamics. This study elucidated the structural composition of runoff components by examining the literature on runoff formation mech…

Polycyclic aromatic hydrocarbons (PAHs) pose significant environmental and health risks in freshwater ecosystems. However, understanding their spatio-temporal dynamics in integrated lake-river systems, particularly with year-round seasonal coverage, remains limited. This study addresses this gap by employing seasonal sampling across all four-quarters (2018–2019), Positive Matrix Factorization (PM…

Wastewater treatment plants (WWTPs) in tourism-driven and climate-sensitive coastal regions experience pronounced seasonal hydraulic variability that challenge conventional performance assessment frameworks. The objective of this study is to apply system dynamics modeling to guide strategic decision-making in the adoption of urine diversion (UD) systems for increased nutrient recovery. Specifical…

Arsenic contamination in soil is one of the major issues faced globally. Arsenic (As(III)) and arsenate (As(V)) are the two common forms of arsenic present in soil, with the former being more mobile and toxic This study systematically investigated the synergistic oxidation and immobilization mechanisms of As(III) in systems combining fulvic acid (FA) with schwertmannite (Sch) under two distinct a…

This study examines the association between corporate climate risk perception, as reflected in the textual content of annual reports, and carbon emissions among Chinese A-share listed firms from 2010 to 2023. Employing textual analysis to construct a firm-level climate risk perception index from Management Discussion and Analysis (MD&A) sections of 31,238 firm-year observations, and using pan…

Organizational support is an important external force for enhancing agricultural green total factor productivity. To identify the interactive and heterogeneous effects of organizational support on agricultural green total factor productivity and investigate the mechanism of knowledge distance, using step-by-step regression method, moderating effect model, grouped regression, and recursive model f…

IntroductionPhotovoltaic (PV) power generation is vital for sustainable energy and carbon reduction, yet existing studies often focus on single aspects, lacking integrated planning support.MethodsThis study develops a framework combining power forecasting, optimization, and carbon assessment using a multidimensional indicator system, PCA, t-SNE, and PSO.ResultsA 1% increase in PV generation could…
