The management of European mountain landscapes is increasingly threatened by rural abandonment and escalating environmental risks. This study investigates an innovative Stewardship–Renewable Energy Communities model for the Central Apennines, exploring how post-seismic public reconstruction can serve as a financial engine for territorial maintenance. Utilizing Open Data Sisma administrative records and Photovoltaic Geographical Information System irradiation metrics, this research assesses the solar potential of 18 municipalities within the Sibillini seismic crater. To ensure a reliable baseline, a Building Suitability Coefficient was introduced as a conservative proxy for the public reconstruction sector. Results indicate that the implementation of a distributed network of 6.5 MWp across 325 public nodes, with a specific yield of 1390 kWh/kWp on the entire area, could generate 9 GWh/year. This translates to approximately EUR 1.08 million in annual revenue from energy incentives and sharing. This economic surplus provides a Stewardship Capacity sufficient to fund the active maintenance of 789.77 hectares per year through Nature-Based Solutions, based on a regional rate of 1200 EUR/ha. The novelty of this study lies in bridging post-disaster energy policy with landscape resilience, demonstrating that distributed rooftop solar portfolios represent a non-invasive, self-funding mechanism. By leveraging the reconstructed public stock, mountain territories can transition from passive neglect to active, energy-backed stewardship, offering a reproducible template for high-value cultural landscapes.

Against the backdrop of increasingly stringent natural forest protection and comprehensive logging bans, forest-dependent regions confront structural constraints between ecological conservation and economic development, necessitating the exploration of alternative livelihood pathways and collaborative governance mechanisms. As a cross-regional institutional synergy arrangement, the “Poverty-Relief Enclave” model integrates factor resources and industrial platforms, thereby offering a new trajectory for income source transformation and industrial succession in forest areas. However, its operational process entails multi-agent interactions and complex incentive and constraint relationships, and the stability of cooperation still warrants systematic investigation. In light of this, this paper constructs a quadripartite evolutionary game model encompassing the host government, the home government, the forest region industrial alliance, and the village collective. Within a bounded rationality and dynamic evolutionary framework, it analyzes the multi-agent strategic evolution process and its stability conditions. The findings reveal that the “Poverty-Relief Enclave” model in forest regions does not spontaneously converge to a high-level cooperative state; rather, three types of stable equilibria may emerge under varying cost–benefit structures and institutional incentives. An ideal state of multi-agent synergy is attainable only under conditions of incentive compatibility. Coordinated supervision by both governments, incentives for high-quality production by industrial entities, and guaranteed participation of village collectives are identified as pivotal factors shaping cooperation stability. The cross-regional institutional arrangement facilitating the “outward shift of income sources” helps alleviate pressure on direct forest resource utilization and fortifies the institutional enforcement foundation through grassroots participation mechanisms. From the perspectives of forest governance and multi-agent collaboration, this study unveils the intrinsic operating mechanism of the “Poverty-Relief Enclave” model in forest regions, thereby furnishing a theoretical underpinning for sustainable transformation and institutional innovation in forest-dependent areas.

Soils as the important components of the global carbon cycle play a critical role in food security as well as in supporting adaptation to climate change. The current review presents recent research on interactions between soil systems and climate dynamics. Climate change and poor land-use practices pose significant threats to soil health. In this context, the application of Sustainable Soil Management (SSM) strategies provides important benefits. These practices contribute to climate change mitigation by increasing carbon storage in soils and improving soil resilience to extreme climate conditions. Regenerative agriculture practices, including Conservation Agriculture (CA), cover crops, organic materials, and diversified cropping systems can store carbon at rates of about 0.1 to 1.2 t C ha⁻¹ yr⁻¹. Moreover, these practices improve biodiversity and enhance soil properties, with yield responses varying depending on environmental and management conditions. Climate change accelerates soil degradation by raising temperatures, altering rainfall patterns, and increasing the frequency of extreme weather events. Consequently, these factors lead to marked reductions in Soil Organic Carbon (SOC) stocks and degrade essential soil properties. This review places SSM within an extensive sustainability framework that is closely linked to the United Nations Sustainable Development Goals (SDGs). Key goals addressed include SDG 2 (Zero Hunger), SDG 13 (Climate Action), and SDG 15 (Life on Land). It also examines related policies, presents case studies from different agroecological regions, and discusses future research directions. Wider adoption of SSM requires strong economic incentives and inclusive governance. These measures can support climate-resilient agriculture and net-zero emission goals. Full article

This study investigates the impact of organic agriculture on farmers’ conservation behaviors, focusing on a sample of 816 households in the Chinese Crested Ibis habitats of Yang County, Shaanxi Province, China. Employing partial least squares structural equation modeling (PLS-SEM), we analyzed the ecological feedback mechanisms bridging agricultural practices and species protection outcomes. The results identify two primary pathways through which organic agriculture fosters conservation: (1) Enhanced perceived benefits directly drive conservation behaviors, with significant path coefficients for ecological benefits (0.105, p < 0.05) and overall benefits (0.290, p < 0.001). (2) Government regulations fortify ecological cognition and conservation efforts (0.123, p < 0.001). Notably, while ecological cognition alone exhibited no direct behavioral impact, ecological emotions emerged as a critical mediator (0.153, p < 0.001). These mechanisms align with the remarkable recovery of the Crested Ibis population—from near extinction to over 7000 individuals—since the reserve’s establishment in 1981. Ultimately, this study highlights organic agriculture’s capacity to generate a positive ecological feedback loop, wherein economic viability and emotional connections to conservation mutually reinforce sustainable behaviors. The findings underscore that personal emotional investment in environmental stewardship is a stronger behavioral catalyst than cognitive understanding alone. This research offers robust empirical evidence to inform policy designs that harmonize agricultural livelihoods with biodiversity goals through targeted organic agriculture incentives and emotionally engaging ecological education programs.

Under the guidance of the “dual carbon” goals, building energy efficiency policies are currently in a critical phase of transitioning from “dual controls on energy consumption” to “dual controls on carbon emissions.” Based on the theory of policy instruments, this paper takes 26 building energy efficiency policy documents issued in Tianjin from 1991 to 2025 as samples. By comprehensively applying content analysis and social network analysis, it systematically examines the evolutionary trajectory, combination characteristics, and structural relationships of policy instruments over the past three decades. This study reveals that Tianjin’s building energy efficiency policy system demonstrates a phased transformation trend—shifting from singular control to diversified incentives and from energy consumption constraints to integrated carbon emission management. The structure of policy instrument combinations has been progressively optimized; however, there remains room for improvement in terms of policy synergy, continuity, and the role of market mechanisms. Consequently, this paper proposes recommendations for optimizing local building energy efficiency policies across dimensions such as instrument coordination, temporal allocation, and mechanism innovation. These suggestions aim to enhance policy implementation effectiveness, accelerate the transition towards energy conservation and carbon reduction in the building sector, and provide empirical references for similar cities seeking to optimize their “dual carbon” policy frameworks.

Jordan is witnessing a growing market trend of retrofitting existing buildings. The annual construction work on existing buildings in Amman, based on building consents, increased by approximately 46% between 2007 and 2017, while the annual newly built areas decreased by around 33%. This paper aims to establish a solid understanding of the current shift towards existing building adaptation in Jordan by exploring the drivers for this trend and the Government’s role in regulating and, possibly, encouraging it. Ten local experts with extensive experience in retrofitting projects in Jordan and around the region were interviewed. The qualitative and quantitative analysis of experts’ answers was performed using the software NVivo. Findings highlight nine main drivers for retrofitting existing buildings in Jordan, namely: (1) land value and location; (2) reducing capital costs compared to new builds; (3) architectural heritage conservation; (4) social and cultural considerations; (5) adapting to population increase; (6) reusing, adapting, and retrofitting to extend the life of buildings; (7) increasing tourism capacity; (8) improving building performance and resource efficiency; and (9) municipal incentives. Not all these drivers have the same value as they depend on the client and the project context. The experts’ ranking of drivers in terms of priority showed higher consideration for land value and location benefits, social–cultural aspects, and population increase, while municipal incentives emerged as low priority. Further research is needed to design context-specific effective retrofit policies, contributing to the literature in this emerging field in Jordan and beyond. Full article

Human–AI systems often involve repeated interaction among users, organizations, and AI components rather than isolated model outputs. In such settings, cooperation can be pursued either by changing agent incentives or by adding an explicit accountability layer. We formalize the Institutional Monitoring and Ledger (IML) framework, which augments a Markov game with monitoring, evidence logging, delayed settlement, and review while leaving the base dynamics unchanged. We derive conservative incentive checks that clarify how detection quality, review accuracy, settlement delay, and sanction size jointly shape deterrence and wrongful-penalty risk. We then provide pilot evidence in two canonical sequential social dilemmas, Harvest and Cleanup, using five agents, PPO training, five training seeds per condition, and comparisons against PPO, inequity aversion, social influence, and IML ablations. In these settings, IML avoided some of the optimization instability observed in the representative internalization baselines tested here, made monitoring error directly visible through ledger records, and showed how false positives can accumulate into a persistent welfare cost. Agent-level analyses in these symmetric environments found nearly uniform measured enforcement burden, while temporal analyses showed that late-stage enforcement is increasingly dominated by residual false positives. These results do not establish legitimacy in human-facing settings or deployment readiness. They instead position IML as a framework with pilot evidence for studying accountability mechanisms in cooperative human–AI systems and highlight measurement error, review design, and due process as central design constraints.

Ports play a pivotal role in global trade but are also associated with significant environmental and social challenges. Despite growing research on green ports, existing studies remain fragmented, with limited integration between technological, environmental, and governance perspectives within the blue economy framework. This review examines the transition from green port initiatives toward integrated blue-economy-oriented port systems by synthesizing recent advances in sustainable maritime infrastructure, smart port technologies, renewable energy integration, and policy frameworks. The analysis reveals three major findings. First, ports are increasingly evolving into energy-integrated hubs, with leading examples adopting shore power systems, renewable energy microgrids, and hydrogen-based infrastructure, thereby contributing to emissions reductions. Second, digitalization through artificial intelligence, IoT, and data-driven logistics significantly enhances operational efficiency, reduces energy consumption, and improves real-time decision-making. Third, effective governance frameworks that combine regulatory measures and incentive-based instruments are critical to accelerating sustainability transitions while ensuring economic competitiveness. In addition, the review highlights the growing integration of biodiversity conservation, marine pollution mitigation, and community engagement into port management strategies, reflecting a shift toward ecosystem-based approaches. Overall, the findings demonstrate that ports are transitioning from conventional logistics hubs into integrated socio-technical systems that enable low-carbon maritime transport while supporting inclusive and resilient coastal development.

Since the start of the U.S. Conservation Reserve Program (CRP) in 1985, producers have enrolled environmentally sensitive land in exchange for annual rental payments, supporting multiple dimensions of sustainability through reduced soil loss, improved water quality, enhanced habitat provision, and strengthened climate resilience through land stewardship. Recent declines in enrollment raise concerns about whether participation remains spatially aligned with local environmental need and economic incentives. This study examines regional variation in CRP participation and its sustainability implications by identifying spatial patterns in participation and key drivers using exploratory spatial data analysis (ESDA). We analyze county-level CRP participation rates alongside three key drivers (CRP rental rates, soil erosion risk on cultivated cropland, and farm income) and assess spatial dependence using Global Moran’s I, univariate Local Indicators of Spatial Association (LISA), and bivariate LISA (BiLISA). Framed as an assessment of agri-environmental policy effectiveness for sustainable land management, the framework is applied to counties in the U.S. Midwest, a region with historically substantial CRP enrollment. Global Moran’s I statistics indicate significant positive spatial autocorrelation for CRP participation (I = 0.491), CRP rental rates (I = 0.892), and soil erosion (I = 0.503), confirming pronounced regional clustering across Midwestern counties. LISA results further show that more than 60% of counties fall into high–high (HH) or low–low (LL) clusters for CRP rental rates, while BiLISA results indicate that 22.9% of counties form HH clusters between CRP participation and soil erosion, suggesting only partial alignment between CRP participation and the environmental need. These findings indicate that the environmental benefits of CRP may vary across the region depending on where participation occurs. Overall, the findings support a shift toward a data-driven, spatially explicit CRP strategy that integrates environmental risk, economic incentives, and regional context to strengthen sustainability outcomes and enhance environmental effectiveness, economic efficiency, and the spatial equity of conservation benefits in the United States.

Water governance faces growing challenges from climate change, pollution, and increasing demand, rendering policy evolution a critical research focus. This study analyzes the evolutionary characteristics of China’s national water resources governance policies from 1988 to 2025 through an integrated quantitative textual analysis. Based on 154 authoritative policy documents, the study employs Latent Dirichlet Allocation topic modeling, semantic network analysis, and a tripartite policy instrument coding scheme (command-and-control, market-based, and public participation instruments). The results reveal three key findings: a significant shift in policy attention from early administrative control toward system-oriented governance emphasizing watershed/ecological protection, conservation, and technology; a persistently imbalanced instrument mix with command-and-control tools remaining dominant, despite gradual diversification after 2000; and a three-stage evolutionary trajectory from administrative framework building (1988–1999), through comprehensive management and diversification (2000–2015), to collaborative innovation and basin/ecology integration (2016–2025). This study contributes a long-term empirical perspective on water policy evolution in an emerging economy, demonstrates an integrated textual-analytic approach, and provides actionable insights for optimizing policy mixes through strengthened incentive compatibility, substantive participation mechanisms, and coherent governance-aligned instrument portfolios.

In the context of China’s transition from “dual control of energy consumption” to “dual control of carbon emissions,” understanding the synergistic mechanisms among carbon emission trading (CET), energy use rights trading (EURT), and electricity markets is critical for achieving the nation’s dual carbon goals. This study develops a system dynamics (SD) model to examine the coupled interactions within this “carbon–electricity–energy” ternary market system, focusing on thermal power enterprises as the primary analytical subject. The model reveals that the ternary market framework drives energy conservation and emission reduction through three key mechanisms: price signal transmission, dual regulatory constraints, and mutual quota recognition. These mechanisms propagate low-carbon incentives throughout the industrial chain by transmitting cost signals to end-users via electricity prices. Compared to binary market structures, the ternary framework achieves superior outcomes, it facilitates higher renewable energy consumption, maintains more stable price levels, enhances market liquidity for both carbon and energy rights, and improves resource allocation efficiency alongside environmental–economic performance. However, the simulation also exposes critical inefficiencies under the current “dual control of energy consumption” regime. The parallel operation of EURT and CET markets creates functional overlap and duplicated compliance burdens. This redundancy increases enterprise costs without commensurate environmental gains, validating the necessity of transitioning to carbon-focused dual control. Further analysis demonstrates that a mutual recognition mechanism between carbon and energy rights effectively alleviates dual compliance pressures and improves enterprise profitability. Optimal market performance emerges when the recognition ratio is appropriately calibrated. Additionally, gradually increasing the share of auctioned quotas while maintaining appropriate levels of free allowances can drive emission reductions without compromising enterprise profitability. This research provides both theoretical foundations and practical policy recommendations for building an efficient multi-market coordination mechanism, facilitating the policy transition, and advancing low-carbon transformation in China’s power sector.

While bioenergy crops are often promoted as a strategy to reduce fossil fuel dependence, adoption among private forest landowners remains limited. This study focuses on private forest landowners enrolled in the West Viginia Forest Stewardship Program, a group characterized by more active management and institutional participation than the broader forest landowner population. We surveyed program participants to identify factors influencing their decision to establish dedicated bioenergy crops. Although general awareness of bioenergy is high, willingness to adopt in the near future remains low. Fewer than 5% of landowners surveyed indicated that they intend to plant bioenergy crops within the next five years. Those who are currently involved in agricultural or forest land use were more likely to adopt, as were those familiar with specific bioenergy crops such as switchgrass, miscanthus, and willow. Participation in government conservation programs also increased adoption likelihood. In contrast, ownership size and age were negatively associated with willingness to adopt. Interestingly, general awareness that many crops can be grown for bioenergy was linked to lower adoption, suggesting skepticism about profitability or feasibility. Farmers were nearly eight times more likely to adopt than non-farmers. The results highlight the need for stable markets, well-aligned incentives, and institutional support rather than information alone. Full article

The public-goods nature of ecological products and heterogeneous stakeholder interests mean that protected areas often face weak coordination, limited incentives, and uneven benefit distribution in the identification, transformation, and return of ecological value. Under increasingly strict conservation objectives, ecological product provision is shifting from direct resource use towards maintaining ecosystem functions and realising experiential value. This helps safeguard ecosystem integrity but raises demands on institutional pathways for value transformation and on the sustainability of community livelihoods. Using Pudacuo National Park in China as a case, this study develops an analytical framework linking supply–demand structures, value chains, and value co-creation, and applies policy document analysis, semi-structured interviews, field observation, and process tracing to examine mechanisms of ecological value realisation under strict conservation. The results show that: (1) a collaborative governance network integrating park authorities, local governments, and concession operators provides a stable organisational basis for ecological value identification and transformation; (2) strengthened provision of non-material ecological products reorients the supply system towards regulating and cultural services, driving a shift from material output to function- and experience-oriented provision; (3) a multi-level community participation model combines labour embedding, livelihood diversification, and institutionalised benefit return to form an ecological value return mechanism grounded in value co-creation. Together, these mechanisms support a relative balance between ecological protection and community development under strict protection and offer empirical insights into the institutional logic of ecological value realisation in strongly protected contexts.

The Yazoo–Mississippi Delta is an agricultural production zone and flyway for migratory birds. During winter, agricultural field-flooding practices are routinely used to support bird conservation and local recreational hunting opportunities. In response to the 2010 Deepwater Horizon oil spill, federal agencies incentivized flooding in summer and fall to mitigate the risks to migratory bird populations. This funding ceased in 2017, yet the United States Department of Agriculture Natural Resources Conservation Service Environmental Quality Incentives Program Practice 644 and a local non-profit continue to incentivize flooding during fall. Ensuring that contractual water levels are met is challenging to determine. To that end, we developed the Field Inundation Tool/Survey, an integrated remote sensing approach using PlanetScope imagery (Planet Labs, San Francisco, CA, USA) to quantify associated hydrology patterns. We used the Normalized Difference Water Index and an Iso Cluster Unsupervised Classification to estimate field inundation and associated habitat types over a three-year period. The results indicate dynamic field inundation can be estimated via PlanetScope imagery. Derived inundation metrics were comparable with in situ sensor and digital elevation models among some treatment types. We documented future refinements for image quality and soil patterns. Our work can improve conservation incentivization by tracking spatial and temporal patterns in adoption and has applicability to other agroecosystems. Full article

As ecosystems decline and their valuable goods and services become scarce, there is growing interest in developing and utilizing environmental markets. Such markets have the potential to reduce environmental risks, provide incentives for sustainable management and restoration, and generate revenue for conservation efforts. The expansion in environmental markets and private finance is particularly significant for developing countries, which host a considerable proportion of global environmental benefits but lack sufficient funds to finance nature conservation. This review examines three types of environmental markets that are relevant to developing countries: markets for sustainably produced commodities; trade in natural resource credits, such as carbon, biodiversity, and water; and nature-based finance markets for natural and ecological assets. The challenges and opportunities impacting the creation and operation of these markets in developing countries are explored. If the opportunities are to be realized, there is a need for policies that support the economic viability of environmental markets and private finance in developing countries, protect the environment and maintain vital ecosystems, while promoting sustainable economic development. This paper offers a unique contribution to the existing literature by examining the emerging environmental markets, innovative funding approaches for environmental conservation and sustainable management in developing countries, and the policies needed to support them.
