Marxist ecological philosophy carries profound implications and serves as the guiding principle for constructing an ecologically advanced society. The essence and fundamental principle of Marxist philosophy is to demand individuals to fully utilize their subjective agency and achieve the harmonization and integration of humanity and the natural world by adhering to objective rules. An extensive examination of Marxist ecological philosophy holds significant theoretical and practical significance in the pursuit of constructing a harmonious and sustainable planet.

This paper calculates the level of digital economy development and the degree of economic and ecological integration in 100 countries from 2009 to 2022 using the entropy weight method and equal weight method. It empirically tests the impact, influencing mechanisms, and spatial effects of the digital economy on the integration of economy and ecology. Furthermore, it analyzes the coordination degree of the digital economy and economic–ecological integration across different continents using coupling coordination analysis. The research results are as follows: First, the digital economy has promoted the integrated development of economy and ecology in various countries, with a more significant effect in high-income and upper-middle-income countries. Countries with higher levels of digital economy development show a more pronounced promoting effect. Second, the digital economy can reduce energy consumption, promote the efficient utilization of clean energy, lower carbon emissions, and thus facilitate the integrated development of economy and ecology through industrial structure optimization and driving technological innovation. Third, a country’s digital economy has a positive spillover effect on the economic and ecological integration development of its neighboring countries. The coupling coordination analysis reveals that Europe has the highest coupling coordination degree of the digital economy and economic–ecological integration, with significant spatial autocorrelation. This is followed by the Americas, Asia, and Africa. Therefore, countries should actively promote digital economy development, strengthen digital economic cooperation, jointly address international environmental and climate issues, and promote the integration of economy and ecology.

In Mucheng Town, Sichuan Province, landscape planning is not just about greenery or streets it’s about how people live, remember, and interact with their surroundings. This research looks at how the town's old ceramic culture and the nature around it, like the Qingyi River, shape public spaces today. The study used field visits, interviews with locals, and looked at government documents. One key finding is that people seem to really support projects that mix usefulness (like walkways or parks) with local stories or traditions. Over the past 2 years, more people have been going to local festivals, and satisfaction with new green areas is high. These things show how cultural and ecological thinking can work together. Other towns, especially those looking to grow without losing their past, might learn from Mucheng’s experience.

The research objective of this paper is to examine the role of bionic design in advancing sustainable development within industrial design by outlining its theoretical framework; analyzing its applications in morphological, functional, and material aspects; identifying current challenges; and projecting future trends toward eco-integration, resource efficiency, and technological innovation. First, the definition, development history, and theoretical basis of the sustainable development of bionic design are outlined. Secondly, the application of bionic design in sustainable industrial design is analyzed in depth, including the application of morphological bionic design in exploring the combination of nature and innovation, the role of functional bionic design in integrating biological function and product innovation, and the harmonious unification of material bionic and environmental friendliness. Finally, it points out the current challenges faced by bionic design, such as barriers in design practice and market acceptance issues, and looks forward to the sustainable development trend of bionic design, including eco-integration, resource efficiency enhancement, technological innovation, integrated application, etc., to provide new ideas and impetus for the sustainable development of the industrial design field in the future.

Phytoindication represents a long-established ecological approach; however, its conceptual basis remains contested, particularly concerning whether it is merely a surrogate for measuring environmental factors or a distinct method for assessing biotic system responses. In this study, we analysed vegetation communities of the sandy terrace in the Dnipro-Oril Nature Reserve (Ukraine) using ecological indicator values, naturalness, and hemeroby indices. The Dnipro-Oril Nature Reserve provides an ideal setting for this study, as it integrates strong natural gradients of soil moisture, nutrient availability, and topography with pronounced anthropogenic influences from the surrounding industrial landscape. This allows the assessment of both natural and human-driven components of ecological variability within a single system. A dataset of 1079 relevés was collected and classified into 24 associations. Multivariate analyses were applied to reveal different aspects of vegetation–environment relationships: MANOVA was used to assess whether plant associations differed significantly in their ecological indicator profiles, CCA to identify the main gradients of species composition constrained by environmental factors, and partial CCA to isolate the specific patterns of vegetation response attributable to individual predictors while controlling for covariates. We found that the indicator values were not independent but strongly intercorrelated, reflecting integrated biotic responses rather than methodological artefacts. This was confirmed by consistent ecological interpretation of the principal component structure and the concordance between ordination patterns and vegetation classification results. Two primary gradients were identified: a natural gradient, which combines soil moisture and nutrient availability with decreasing light, temperature, continentality, and soil pH; and an anthropogenic gradient, represented by the hemeroby–naturalness axis. The interplay of these gradients offers a comprehensive explanation for vegetation structure across various spatial scales, with natural factors shaping community types and anthropogenic influences exerting broader, less specific effects due to their diffuse impact across multiple plant associations. Our findings reveal a novel conceptual perspective, supporting the view that phytoindication is a unique ecological tool for assessing the integrated response of plant communities to environmental drivers, including both natural and anthropogenic gradients, rather than a simplified or less precise substitute for instrumental measurements. Nevertheless, the use of phytoindication does not eliminate the need for instrumental measurements in situations requiring precise quantification of specific physical or chemical environmental parameters. The correlated structure of indicator values revealed in this study demonstrates that phytoindication patterns are specific to each landscape. Therefore, comparative assessments across regions or time periods should be based on the correlation patterns of indicator values rather than their absolute scores.

This essay takes initial steps on a journey with an Irish eco-spiritual philosopher, the late John Moriarty. As a gateway into his broader oeuvre and way of thinking, we explore Moriarty’s image of the Christian mystical Easter journey—the Triduum Sacrum—as a vision for humanity and the planet. After briefly reviewing his spiritual biography, we consider Moriarty’s re-framing of the story as a journey to the bottom of a symbolic Grand Canyon, a mystical trail beyond historical time to a primordial unity before the evolution of the species. There, the total integration of the natural ecumene is experienced. For Moriarty, this journey leads not only into the past, but prefigures a pilgrimage that everyone can—and should—take. Analyzing primarily his own writing, we highlight the intercultural roots and ecumenical connections of Moriarty’s work, which draws extensively on spiritual traditions and contemporary debates from across the world. On that basis, we sign-post directions for further research into a potential post-Christian ecology as a new way of thinking about the earth and our role on it, based on an attitude of Gelassenheit.

Rural sustainability is key to maintaining prosperity in developed rural areas, yet many existing evaluation methods focus on material resources while overlooking villagers’ perceptions. This study introduces an ecological–livelihood–perception ( ELP ) model that extends the sustainable livelihoods framework (SLF) by refining its natural capital dimension to explicitly incorporate ecological quality and villagers’ environmental perceptions, alongside a psychological perception derived from a self-fulfilling prophecy theory. We conducted a structured survey of 100 households in Guoliang village. Then, 21 standardized indicators spanning the natural, financial, physical, social, human, and ecological dimensions were introduced to evaluate the survey data. After reliability screening, principal component analysis (PCA) was applied to construct a single composite score for each capital, capturing the dominant variance in the data without multicollinearity. PCA combined with entropy-based weighting was applied to reduce collinearity and derive indicator weights. Descriptive results show that normalized indicator means range from 0.15 to 0.86, and indicator weights are relatively balanced, ranging from 0.044 to 0.051, with the highest-weight indicator reaching 0.051. The sustainable individual perception ( SIP ) index was calculated from qualitative items and was linked to the six capital scores through an ordinary least squares regression. The results reveal a threshold pattern: once a basic level of natural capital is met, it leads to further gains, especially in social and ecological assets, which are strongly associated with higher psychological optimism. Households exhibiting high SIP consistently possess balanced and multidimensional capital portfolios, whereas those with low SIP show deficits across most dimensions. The ELP model, therefore, provides a more comprehensive tool for rural sustainability evaluation by integrating objective livelihood assets with subjective perceptions, offering practical insights for targeted policy interventions and development strategies.

This study investigates the foundational causes of unsustainability that obstruct efforts to address global challenges such as climate change, environmental degradation, water crises, and public health deterioration. Using qualitative research with in-depth expert interviews from education, environmental studies, and business, it finds that these global challenges, while visible on the surface, are deeply rooted in worldviews that shape human behavior, societal structures, and policies. Building on this insight, the thematic analysis manifests three interrelated systemic paradigms as the fundamental drivers of unsustainability: a crisis of wholeness, reflected in fragmented identities and collective disorientation; a disconnection from nature, shaped by human-centered perspectives; and the influence of dominant political-economic systems which prioritize growth logics over ecological and social concerns. These paradigms underlie both structural and cognitive barriers to systemic transformation, which influence the design and implementation of education for sustainability. By clarifying a body of knowledge and systemic paradigms regarding unsustainability, this paper calls for transformative education that promotes a holistic, value-based approach, eco-empathy, and critical thinking, aiming to equip future generations with the tools to challenge and transform unsustainable systems.

A process based model integrating the effects of UV‐B radiation to molecular level processes and their consequences to whole plant growth and development was developed from key parameters in the published literature. Model simulations showed that UV‐B radiation induced changes in plant metabolic and/or photosynthesis rates can result in plant growth inhibitions. The costs of effective epidermal UV‐B radiation absorptive compounds did not result in any significant changes in plant growth, but any associated metabolic costs effectively reduced the potential plant biomass. The model showed significant interactions between UV‐B radiation effects and temperature and any factor leading to inhibition of photosynthetic production or plant growth during the midday, but the effects were not cumulative for all factors. Vegetative growth were significantly delayed in species that do not exhibit reproductive cycles during a growing season, but vegetative growth and reproductive yield in species completing their life cycle in one growing season did not appear to be delayed more than 2–5 days, probably within the natural variability of the life cycles for many species. This is the first model to integrate the effects of increased UV‐B radiation through molecular level processes and their consequences to whole plant growth and development. We modeled the effects of UV‐B radiation from molecular interactions to whole plant growth. Cost of secondary metabolites might not be significant. There were significant UV‐B radiation – temperature interactions. Growth was delayed 2–5 days per growing season.
