This study examines the impact of public data openness on environmental welfare performance using a quasi-natural experimental approach based on the establishment of prefecture-level city public data openness platforms. Our findings reveal that public data openness significantly improves urban environmental welfare performance. Furthermore, heterogeneity analysis highlights that public data openness can play a more positive role in cities in eastern China, cities with greater fiscal autonomy, and cities where local governments place greater emphasis on environmental protection. Mechanism analysis demonstrates that public data openness enhances environmental welfare performance through stricter environmental regulatory constraints, industrial structure upgrading, increased public participation and supervision, and advancements in innovation and entrepreneurship. Extensive analysis shows that public data openness within a spatial framework can significantly enhance environmental welfare performance in the region. However, this process will generate a triple “siphon effect” that inhibits improvements in urban environmental welfare performance in surrounding areas. Additionally, this effect exhibits a certain degree of geographical attenuation influenced by economic interdependence, with an attenuation boundary of 1000 km. This study injects internet and big data thinking into ecological civilization construction, endowing it with new models, new scenarios, and new momentum, and providing a brand-new approach to sustainable development practices.

The yak (Bos grunniens) is a key species in high-altitude rangelands of Asia. Despite their ecological and economic importance, yak production faces persistent challenges, including low milk yields, vulnerability to climate changes, emerging diseases, and a lack of systematic breeding programs. This review presents the genomic, physiological, and environmental dimensions of yak biology and husbandry. Genes such as EPAS1, which encodes hypoxia-inducible transcription factors, underpin physiological adaptations, including enlarged cardiopulmonary structures, elevated erythrocyte concentrations, and specialized thermoregulatory mechanisms that enable their survival at elevations of 3000 m and above. Copy number variations (CNVs) and single nucleotide polymorphisms (SNPs) present promising markers for improving milk and meat production, disease resistance, and metabolic efficiency. F1 and F2 generations of yak–cattle hybrids show superior growth and milk yields, but reproductive barriers, such as natural mating or artificial insemination, and environmental factors limit the success of these hybrids beyond second generation. Infectious diseases, such as bovine viral diarrhea and antimicrobial-resistant and biofilm-forming Enterococcus and E. coli, pose risks to herd health and food safety. Rising ambient temperatures, declining forage biomass, and increased disease prevalence due to climate changes risk yak economic performance and welfare. Addressing these challenges by nutritional, environmental, and genetic interventions will safeguard yak pastoralism. This review describes the genes associated with different yak traits and provides an overview of the genetic adaptations of yaks (Bos grunniens) to environmental stresses at high altitudes and emphasizes the need for conservation and improvement strategies for sustainable husbandry of these yaks.

Air pollutants, such as particulate matter (PM) and ammonia (NH₃), generated by intensive animal farming pose considerable threats to human health, animal welfare, and ecological balance. Conventional materials are often ineffective at simultaneously removing multiple pollutants, maintaining a low pressure drop, and ensuring durability in heavily polluted environments. Inspired by the dust-retention properties of Pinus sylvestris var. mongolica (PS) needles, this study developed a biomimetic grooved ribbon fiber using electrospinning technology. These fibers were further assembled into a three-dimensional bioinspired aerogel structure through freeze-forming technology to achieve efficient dust capture. Additionally, the introduction of UiO-66-NH₂ nanoparticles significantly enhanced the properties of the aerogels for NH₃ adsorption. Among the various prepared aerogels (PG, UPG-5, UPG-10, UPG-15, and UPG-20), UPG-10 demonstrated the best performance, achieving a filtration efficiency of 99.24% with a pressure drop of 95 Pa. Notably, it exhibited a remarkable dust-holding capacity of 147 g/m², and its NH₃ adsorption capacity reached 99.89 cm³/g, surpassing PG aerogel by 31.46 cm³/g. Additionally, UPG-10 exhibited outstanding elasticity, maintaining over 80% of its original shape after 30 compression cycles. This biomimetic aerogel presents a promising solution for air purification, contributing to improved agricultural efficiency and environmental sustainability. Full article

Welfare quality is usually a stochastic outcome, as attempts at improving social welfare cannot be predicted in advance. The advances in stock market participation conclude that equity market performance is able to reflect investors’ mass reactions and therefore can fairly reflect the empiricism of welfare quality. In this paper, the pillars of the Happy Planet Index (hereinafter HPI) are used as proxies for countries’ welfare quality. The data cover 57 countries where equity markets exist over the annual period of 2006–2020. The results indicate that (a) the three pillars of HPIs have historical positive impacts on market capitalization and stock turnover; (b) stochastically, life satisfaction has an expected positive impact on market capitalization and stock turnover; (c) firms located in high (low) HPIs, life satisfaction, and life expectancy have significant (insignificant) stochastic impacts on market capitalization; and (d) the historical ecological footprints have positive impacts on market capitalization and stock turnover, whereas stochastic impacts are statistically insignificant.

The sustainability of the Arabica coffee agribusiness is increasingly urgent as global demand grows while environmental and socioeconomic challenges intensify. North Toraja, renowned for its high-quality Arabica coffee, faces significant barriers to sustainability, including poor infrastructure, limited adoption of modern agricultural technologies, and socioeconomic disparities among coffee farmers. These issues threaten the long-term viability of the sector, which is a critical contributor to local livelihoods and the regional economy. This study evaluates the sustainability of the Arabica coffee agribusiness in North Toraja using a Multidimensional Scaling (MDS) approach, assessing five key dimensions: ecological, economic, social, infrastructure and technology, and institutional. Data were collected through Focus Group Discussions with stakeholders across the coffee value chain and secondary sources. The results reveal a moderately sustainable overall index of 73.78, with the economic and institutional dimensions performing strongly at 87.53 and 84.91, respectively. However, the infrastructure and technology dimension scored the lowest at 55.77, highlighting significant deficiencies in road conditions, postharvest handling, and access to advanced farming technologies. To enhance sustainability, this study recommends strategic investments in rural infrastructure, training programs to promote technology adoption, and strengthening institutional frameworks such as cooperatives and government programs. Inclusive social policies that address equity and community engagement are also crucial. By addressing these gaps through a comprehensive, multidimensional approach, North Toraja’s Arabica coffee sector can achieve greater sustainability, improving farmer welfare and ensuring competitiveness in the global market. These findings serve as a model for sustainable coffee production in similar regions. Full article

The “dual carbon” goal has become a major national strategy, an inherent requirement for high-quality economic development. As a crucial indicator of measuring sustainable development capabilities, ecological welfare performance has emerged as a core tool for enhancing human welfare, achieving sustainable development, advancing ecological civilization construction, and promoting green development. This study focuses on the “dual carbon” goal appeal, clarifies the concept connotation of ecological welfare performance, assesses the research progress of ecological welfare performance, deeply analyzes the internal relationship between the “dual carbon” goal and ecological welfare performance, builds a research framework for ecological welfare performance, and points out the marginal contribution, research prospects, and shortcomings of ecological welfare performance research under the “dual carbon” goal. The findings are as follows: (1) Research on ecological welfare performance has shifted from a single dimension to a multi-dimensional and multi-level comprehensive consideration, involving multiple disciplines. Literature research focuses on four aspects, namely, the connotation and representation of welfare, the interaction between ecosystems and welfare, ecological welfare performance research, and “dual carbon” target and ecological welfare performance research. (2) From the perspective of research hotspots and historical evolution, most scholars pay more and more attention to empirical research and application-oriented research, and it is still necessary to constantly explore new theoretical frameworks and methodologies in the future to better understand the changing rules and driving mechanisms of ecological welfare performance. (3) From the perspective of the ecological welfare performance research framework, an in-depth analysis of the relationship between natural ecological consumption, economic growth, and welfare is carried out. Based on the change in research paradigm, a two-stage ecological welfare performance evaluation framework is constructed to promote the realization of the “dual carbon” goal and the continuous optimization of ecological welfare performance, so as to provide a reference basis for the scientific assessment of sustainable development capacity.

Based on the panel data of 283 prefecture-level cities in China from 2010 to 2021, this paper takes the pilot policy of “Broadband China” as a natural experiment to evaluate the impact of digital infrastructure construction on urban ecological welfare performance and its mechanism by using a progressive difference–difference model. The results show that China’s digital infrastructure construction will significantly reduce the performance of urban ecological welfare. Through the analysis of input and output, it is found that the construction of digital infrastructure can significantly reduce resource consumption and increase welfare output, especially economic welfare, but at the level of environmental pollution, it will significantly increase the discharge of industrial wastewater, which may be the main reason for the negative effect of digital infrastructure construction. Through the group analysis, it is found that the overall negative impact of digital infrastructure construction on ecological welfare performance may be caused by the ecologically fragile western region and the unreasonable industrial structure. Through the adjustment model, it is found that innovation investment can positively regulate the negative impact of digital infrastructure on ecological welfare performance. The grey model (GM) is further used to forecast the data for 2022–2025, and it is found that while the negative impact of digital infrastructure is decreasing, it is still significant. This study provides empirical evidence for accurately understanding the effect and mechanism of digital infrastructure construction on ecological welfare performance. Full article

IMTA is one of the most innovative and sustainable farming systems, exhibiting the best technique available in rearing aquatic organisms belonging to different positions along the trophic levels. In the literature and in legislation, the environmental benefits of IMTA protocols have been extensively recognized, mainly for its capability to reduce the ecological footprint of intensive aquaculture systems and concretely address the Sustainable Development Goal no. 14 (SDG 14). However, lesser attention is given to the assessments of its role in enhancing the zootechnical performance, animal welfare, and flesh quality of the species involved. To the best of our knowledge, this is the first review that aims to offer a systematic analysis of the existing literature on the main commercial motivations that could draw the attention of stakeholders, including consumers and fish farmers, towards a greater social acceptability and implementation of the IMTA system on a large scale. The findings suggest that, beyond its environmental advantages, IMTA systems can positively influence the productivity, growth, survival, feed efficiency, and animal health and welfare (AH&W), as well as the nutritional quality of the harvested species, thus offering significant economic and market value both in terms of Environmental, Societal and Governance (ESG) parameters and One Health.

Zoo enclosure design, and housing and husbandry protocols, will always be a compromise between what a species has evolved to do and what is possible to offer in a human-created environment. For some species, behaviours that are commonly performed in the wild may be constrained by husbandry practices that are used for ease or aesthetics or are accepted conventions. As zoos place more emphasis on positive animal welfare states, zoo enclosures should be scrutinised to check that what is provided, in terms of useful space, appropriate replication of habitat features, and maximal potential for natural behaviour performance, is relevant to the species and individuals being housed. For some species, zoos need to grapple with tough questions where the answer may not seem immediately obvious to ensure they are continuously improving standards of care, opportunities for the performance of species-typical behaviours, and advancing the attainment of positive welfare states. Determining the importance of flight, for example, and what this behaviour adds to the quality of life of a zoo-housed bird, is an important question that needs addressing to truly advance aviculture and how we determine bird welfare. This paper provides questions that should be answered and poses measures of what flight means to a bird, to provide evidence for the development and evolution of zoo bird housing. If we can devise some way of asking the animals in our care what they need, we can more firmly support decisions made that surround enclosure design, and housing decisions. Ultimately, this means gathering evidence on whether birds like to fly (e.g., from birds in training or demonstration activities) by applying mixed methods approaches of behavioural analysis, data on wild ecology, qualitative behavioural assessment, and cognitive bias testing to develop a robust suite of tools to address avian welfare considerations. Avian welfare scientists should attempt to define what meaningful flight is (i.e., flight that truly suggests a bird is flying) in order to support guidelines on aviary dimensions, space allowance, and welfare outputs from birds in both flighted and flight-restricted populations, and to determine what is most appropriate for an individual species. Changing the term “best practice” husbandry guidelines to “better practice” husbandry guidelines would instil the importance of regular review and reassessment of housing and management suitability for a species to ensure such care regimes remain appropriate. With an increasingly welfare-savvy public visiting zoos, it is essential that we seek more evidence to support and justify how birds are kept and ultimately use such evidence to enact changes to practices that are shown to infringe on avian welfare.

Agriculture is not only the source of carbon emissions, but also an important carbon sink. The development of low-carbon agriculture in China is closely related to achieving the national strategic goal of “dual carbon.” Reducing carbon emissions in China’s agricultural sector and accelerating the development of ecological low-carbon agriculture (ELA) are extremely important and urgent, both from the perspective of the long-term common welfare for mankind and from the perspective of maintaining the sustainable development of agriculture itself. However, ELA is still an emerging concept in China, and its connotation and characteristics are not yet clear. There is a lack of effective paths for orderly and scientific promotion of the development of ELA in China. Based on this, this paper focuses on the emerging concept of ELA and examines ELA with Chinese characteristics from the dimensions of connotation, features, practical issues, and pathways, aiming to provide guidance for the sustainable development of ELA in China. The research results indicate that there are regional development imbalances, low willingness of farmers to participate, insufficient technological reserves, and difficulties in realizing the value of ecological products in China’s ELA. It is necessary to improve the modern agricultural production and operation system, tap into the potential of agricultural emission reduction and carbon sequestration, build a technical system to support the development of ELA, and establish a sound mechanism for realizing the value of ecological products. By continuously improving the regional organizational capacity and performance of ELA, accelerating the advancement of ELA technology and demonstrating its regional promotion, and by establishing and continuously improving the support system for ELA, one can promote the sustainable development of ELA in China. In addition, the research findings of this paper can also provide reference for the ecological low-carbon development of the global agricultural sector, supporting the contribution of the agricultural sector to achieving high-quality global sustainable development goals.

Enhancing urban ecological welfare performance is essential for achieving sustainable urban development and fostering a comprehensive regional green transformation. This study develops a quantitative assessment framework for urban ecological welfare performance, grounded in both the welfare of urban residents and their consumption of ecological resources. Employing the spatio-temporal Logarithmic Mean Divisia Index model to dissect the ecological welfare performance across 108 key prefecture-level cities within China’s Yangtze River Economic Belt, considering both temporal and spatial dimensions, the analysis reveals a “W”-shaped trajectory in the ecological welfare performance from 2006 to 2022, characterized by pronounced spatial disparities. Particularly in the downstream coastal regions and notably the Yangtze River Delta, advantages in social and economic structures, along with public fiscal outlays, contribute to a superior ecological welfare performance, exhibiting a notable spatial spillover effect. The study introduces six key factors—social benefit, economic benefit, population dispersion, population density in urban areas, urbanization scale, and ecological sustainability—to examine their influence on ecological welfare performance, uncovering substantial differences in the outcomes of temporal and spatial decomposition. Temporal decomposition indicates that economic benefit and urbanization scale are the primary drivers enhancing ecological welfare performance, whereas population dispersion is identified as the primary inhibitor. Spatial decomposition reveals that the determinants of above-average urban ecological welfare vary regionally and undergo dynamic shifts over time. Overall, a holistic understanding of the interplay among economic growth, ecological preservation, and the enhancement of residents’ welfare can inform the development and execution of tailored policies by local governments.

Assessments of farmer satisfaction can be a crucial tool for effectively implementing an appropriate ecological compensation policy. This study evaluates the effectiveness of an ecological compensation policy for crop rotation in China’s black soil regions from the perspective of farmer satisfaction. Specifically, utilizing an improved entropy TOPSIS, logistic regression, and the obstacle degree model, this empirical study analyzes the performance of the ecological compensation policy for crop rotation in black soil regions and identifies barriers in Heilongjiang Province. The findings indicate that gender significantly and positively affects outcomes at the 10% level, while age has a notable influence at the 5% level. Additionally, the family labor force and the quality of cultivated land, both significant at the 5% level with negative coefficients, suggest a diminished likelihood of farmers participating in these ecological compensation projects. The family’s source of income, significantly influential at the 1% level, also indicates a lower propensity among farmers to engage. Performance analysis reveals that the values for variables of satisfaction with the project’s publicity (A1), satisfaction with the protection of farmers’ rights and interest (A3), overall satisfaction with the effectiveness of the project (B1), satisfaction with ecological compensation methods (B3), and satisfaction with household income after the implementation of the project (C1) are above the average. In contrast, values for variables of satisfaction with the supervision and management (A2), satisfaction with the payment of ecological compensation funds (A4), satisfaction level with black soil rotation ecological compensation standards (B2), satisfaction with the welfare level of family life after the implementation of the project (C2), and satisfaction with farmers’ proactive participation in the project (D1) fall below the average of 3.03. Therefore, this study provides a comprehensive framework for assessing the effectiveness of the ecological compensation policy for crop rotation in China’s black soil regions and offers recommendations for enhancing its performance.

Ecological well-being performance (EWP) is a key indicator of sustainable development and has garnered significant research attention. This study measures the overall and stage-by-stage efficiency of the urban agglomerations in the Yellow River Basin based on the ends–means framework of steady-state economics. This study then delves into the spatiotemporal transfer characteristics of EWP through Moran’s I, and spatial Markov chains. Additionally, this research investigates the factors influencing EWP using a random forest model. The findings indicate a notable enhancement in EWP in the urban agglomerations in the YRB from 2006 to 2021, showing clear spatial agglomeration patterns. The shift in EWP types displays a “path dependence” effect, with distinct evolutionary paths influenced by spatial lag effects. Ecological input emerges as a key internal driver of EWP, while urbanization and technological advancements are highlighted as significant external factors. Industrial agglomeration and industrial structure also contribute to improving EWP. The findings of this study help to clarify the spatial and temporal characteristics of ecological welfare performance and its driving mechanisms in the urban agglomerations of the Yellow River Basin. This is conducive to the achievement of high-quality urban transformation and regional green development, and it provides a reference for the construction of an ecological civilization. Full article

Ecological welfare performance (EWP) serves as a crucial measure for assessing the green development of a region. Exploring the spatial characteristics, network structure, and transfer paths of its specific stages is crucial for grasping an internal space’s EWP and optimizing urban ecological planning. This research employed a two-stage DEA model to assess the EWP of 284 Chinese cities from 2007 to 2022 and decompose it into an ecological–economic transition stage (L1) and an economic welfare transition stage (L2). Second, a social network analysis (SNA) was conducted to describe the EWP sub-stages’ network structure and construction mechanism. Finally, the transmission path process of EWP was revealed through Markov chains. It is found that (1) the overall trend of EWP is rising and then falling, with L2 as the critical constraint; (2) the network structure of the two stages is complex, dominated by industrial structure, urbanization, and healthcare level; and (3) ‘club integration’ constrains the transfer across EWP in the short term. Compared with L2, which has a lower probability of interstate transfer, L1 has a greater likelihood of transfer to a higher level. This paper provides suggestions for the optimal allocation of ecological resources in Chinese cities through the analysis of EWP. Full article

Understanding animal behaviour can feel like deciphering a foreign language. In 1963, pioneering ethologist Nikolaas Tinbergen offered a key: four fundamental questions to dissect behaviour’s complexities and reduce interpretive bias. These “Four Questions” fall into two categories: Proximate (how?) and Ultimate (why?). The Proximate questions ask how the behaviour is triggered (Causation) and develops over time (Ontogeny). The Ultimate questions delve into its evolutionary history (Phylogeny) and purpose (Function). Traditionally used in behavioural ecology, Tinbergen’s framework finds new relevance in fields like sentience, welfare, conservation, and animal management. This paper illustrates how further integration of these Questions into applied research can improve outcomes. For example, captive animals can receive enrichment seemingly “unnatural” in origin and form. Does such enrichment trigger species-typical behaviours, fulfilling the same adaptive function as natural stimuli would? Understanding a species’ natural behaviour patterns and how the performance of such activities promotes positive welfare states is key to biologically relevant population management. Tinbergen’s Four Questions can help scientists to decipher the relevance of natural behaviour, and how a species’ responses to their environment indicate what individuals need and want at a specific time or place. By applying the Four Questions, we can answer this question and, in turn, refine husbandry practices and conserve behavioural diversity in managed populations. Sixty years after their conception, Tinbergen’s Four Questions remain a powerful tool for behavioural research. By embracing different biological disciplines within a unified framework, applied animal zoo science will continue to advance and provide credible evidence-based outputs. Full article
