The increasing demand for food and the overexploitation of natural resources rapidly deplete the planet’s ecosystems, highlighting the urgent need for sustainable alternatives. Nature-based solutions effectively promote agricultural sustainability and environmental conservation but require continuous financial and political support to overcome existing barriers. This research examines these solutions’ effectiveness in Santa María Jacatepec, a biocultural region of Indigenous peoples in the Papaloapan Basin, Oaxaca, Mexico. A mixed-methods approach combining quantitative and qualitative analyses uses National Institute of Statistics and Geography data to evaluate socioeconomic and environmental indicators. The results indicate that despite pressures to develop cattle ranching, communities have maintained rain-fed agriculture, especially the milpa system, ensuring food sovereignty and preserving agricultural biodiversity. Additionally, implementation of Voluntarily Conserved Areas has facilitated access to payments for environmental services, incentivizing ecosystem protection. However, financial and structural challenges persist, limiting the expansion of these solutions. Santa María Jacatepec exemplifies how Indigenous communities can apply nature-based solutions to strengthen agricultural sustainability and environmental conservation. Integrating traditional knowledge and strengthening conservation policies can enhance community resilience and ensure sustainable development amid increasing pressure on natural ecosystems.
对粮食日益增长的需求和对自然资源的过度开发迅速耗尽了地球的生态系统，凸显了对可持续替代品的迫切需求。基于自然的解决方案能有效促进农业可持续发展和环境保护，但需要持续的财政和政治支持来克服现有障碍。本研究考察了这些解决方案在墨西哥瓦哈卡州 Papaloapan 盆地的原住民生物文化区 Santa María Jacatepec 的有效性。采用定量和定性分析相结合的混合方法，利用国家统计和地理研究所的数据来评估社会经济和环境指标。结果表明，尽管面临发展畜牧业的压力，社区仍保持了雨水灌溉农业，尤其是密帕系统，从而确保了粮食主权并保护了农业生物多样性。此外，"自愿保护区 "的实施促进了环境服务付费的获得，激励了生态系统保护。然而，资金和结构方面的挑战依然存在，限制了这些解决方案的推广。圣玛丽亚-雅卡特佩克（Santa María Jacatepec）是土著社区如何运用基于自然的解决方案来加强农业可持续性和环境保护的典范。在自然生态系统面临越来越大压力的情况下，整合传统知识和加强保护政策可以增强社区的复原力，确保可持续发展。

Open-pit mining seriously damages the original vegetation community and soil layer and disturbs the carbon cycle of vegetation and soil, causing instability in the mining ecosystem and decrease in the carbon sequestration capacity of the mining area. With the deepening of environmental awareness and the influence of related policies, the ecological restoration of open-pit mines has been promoted. The mining ecosystem is distinct owing to the disperse distribution of mines and small scale of single mines. However, the carbon sequestration capability of mines after ecological restoration has not been clearly evaluated. Therefore, this study evaluated the carbon sequestration capacity of restoration mines, taking the mines of the Yangtze River Basin in Jurong City, Jiangsu Province as the research objects. Firstly, the visual effects of the vegetation and soil in their current status were determined through field investigation, the methods for sampling and data collection for the vegetation and soil were selected, and the specific laboratory tests such as the vegetation carbon content and soil organic carbon were clarified. Meanwhile, the evaluation system consisting of three aspects and nine evaluation indexes was established by using the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation (FCE). The process of evaluation included the following: the establishment of the judgment matrix, calculation of the index weight, determination of the membership function, and establishment of the fuzzy membership matrix. Finally, the evaluation results of the restoration mines were determined with the ‘excellent, good, normal and poor’ grade classification according to the evaluation standards for each index proposed considering the data of the field investigation and laboratory tests. The results indicated that (1) the evaluation results of the mines’ carbon sequestration capacity were of excellent and good grade at a proportion of 62.5% and 37.5%, which was in line with the field investigation results and demonstrated the carbon sequestration capacity of all the restored mines was effectively improved; and (2) the weights of the criterion layer were ranked as system stability > vegetation > soil with the largest value of 0.547, indicating the stability of the system is the main factor in the carbon sequestration capacity of the mines and the sustainability of the vegetation community and the stability of soil fixation on the slope. The proposed evaluation system effectively evaluates the short-term carbon sequestration capability of the restoration mining system according to the visual effects and the laboratory testing results, objectively reflecting the carbon sequestration capacity via qualitative assessment and quantitative analysis. The evaluation method is relatively applicable and reliable for restoration mines and can provide a reference for similar ecological restoration engineering.

The Industrial Revolution and technological advancements have led to the densification and expansion of cities. In urban environments, residential buildings are common, and optimizing energy use in these structures is achieved by focusing on key parameters during the early design phases. These parameters can be tested through simulations. This study aims to define the scope of energy simulations in residential design to contribute to design optimization and reduce energy consumption. A systematic literature review and qualitative analysis were employed, using the PRISMA protocol for data collection and Vosviewer and Bibliometrix tools for bibliometric analysis. The keywords obtained were subjected to qualitative analysis. The research revealed the absence of a standardized approach in simulation studies. To address this, a nine-step framework has been proposed. A discrepancy between the objectives of certain studies and the keywords used was identified. Themes were created based on the studies’ objectives, and keywords were recommended accordingly. Several studies have determined the energy potential of buildings during the occupancy phase. Simulations should be integrated into the early design phase to facilitate pre-design optimization. A framework for residential simulation methodology was developed, believed to enhance the validity of studies and facilitate result comparisons. Minimizing energy consumption is a primary objective in residential buildings. The recommendations developed align with the United Nations’ Sustainable Development Goal 11: Sustainable Cities and Communities.

Solar energy is increasing in popularity as a renewable energy source, which reduces greenhouse gas emissions. Even though many governments promote solar energy by giving various incentives, its adoption rate in households is slow. Psychological factors have been relatively overlooked in solar adoption, despite the importance of social and economic factors. Therefore, the purpose of this study is to investigate how psychological determinants impact households’ willingness to install solar photovoltaic (PV) systems. This study focusses on the future orientation and personal values (biospheric, altruistic, and egoistic values) of households’ and their willingness to install solar PV systems. The research draws from three environmental psychology theories: values orientation theory, value beliefs and norms theory, and the theory of planned behaviour to construct an integrative theoretical model. A survey involving 179 respondents in Australia was conducted and analysed applying the PLS-SEM technique. Findings revealed that future orientation and values are significant predictors of household willingness to install solar PV systems. Further, findings showed that attitude and perceived behavioural control play a significant role in installing solar. The findings will assist policymakers and solar companies in developing lucrative policies and marketing strategies to promote solar PV systems among households.

The traditional villages along the Wanli Tea Road carry rich historical and cultural heritage, holding significant humanistic and scientific value. However, with the rapid pace of urbanization and modernization, the inheritance and protection of the cultural landscapes in these traditional villages face numerous challenges. Based on this, this study focuses on Xiamen Village, a traditional village along the Jinzhong section of the Wanli Tea Road, utilizing the perspective of the landscape gene information chain to reveal the performance and genetic characteristics of its unique and regionally distinctive cultural landscape genes. The study provides theoretical support for the protection and inheritance of cultural landscapes in traditional villages along the Wanli Tea Road. The results show that: (1) The overall cultural landscape of Xiamen Village has been well preserved, with notable characteristics in environment, layout, architecture, and culture, demonstrating its rich historical and cultural accumulation, and offering high research and conservation value; (2) The landscape gene information chain of Xiamen Village plays a critical role in integrating the village’s cultural landscape. The landscape gene information elements and points express the village’s unique historical inheritance through regional culture and material forms. The “branch-like” structure of the landscape gene information corridors effectively connects the various landscape gene information points, while the landscape gene information network reflects the interaction between tradition and modernity; (3) The landscape gene information chain of Xiamen Village shows a relationship of coexistence between inheritance and change in its genetic characteristics. Although some landscape genes face challenges from modernization, their core traits have not been lost. The inheritance of the landscape genes is not static but adjusts and reconstructs within an evolving social and cultural context, reflecting adaptability and flexibility in response to modern demands.

The construction industry plays a substantial role in shaping the economies of many countries. Construction management faces various challenges that can lead to project failures, particularly in infrastructure projects struggling to meet cost and time requirements. Inadequate project planning and the intricate nature of construction projects can cause participants’ project goals to not align. It is crucial to address these challenges early in the planning stages to ensure project success. This research involved investigating previous studies to understand current practices for improving infrastructure project planning and selecting the best pre-project planning tool. Infrastructure projects in the Saudi construction industry are used as a case study. A questionnaire was prepared based on essential alignment issues affecting team alignment during pre-project planning. Participants rated the level of agreement with alignment issues and the overall success of a project they worked on. The study utilized descriptive and inferential analysis techniques to assess infrastructure project success rates and develop a predictive model driven by the alignment tool. Multiple linear regression techniques were used during the model’s development, and validation and reliability outputs were obtained. By evaluating all relevant stakeholders, the model generates a score to facilitate the pre-project planning process, increasing the likelihood of project success. The study found that the model’s predictive accuracy was 94%. This research is significant in creating a predictive model applicable to infrastructure projects, enhancing project management practices by enabling project teams to evaluate project progress, identify projects in need of corrective action, and ultimately improve project performance, leading to cost and time savings.

This paper identifies the major aspects that affect the sustainability of organizations in terms of success and failure of IT implementation projects. A significant relationship between the deployment of internal project teams and sustainable results of IT implementation projects compared to professionals employed via outsourcing was found. Moreover, involving professional managers with hands-on experience and knowledge of the organization in decision-making processes positively affects the project outcomes and the sustainability of the organization. Employee workload concerns are the least impactful on project overrun, while other concerns are less sustainable. Finally, a methodology that enhances the likelihood of sustainable results in IT implementation projects by involving professional managers and forming in-house teams is presented.

The presented review concerns the cross-disciplinary approaches to the subject of blue food and blue colourants, the socio-cultural aspects of blue food and beverage consumption, human health effects, environmental impact, and economic aspects. Blue colour in relation to food is not only about improving visual appeal, to which the addition of food colouring is usually limited when the food is coloured in some way that does not encourage eating. It is also the rich and complex sociological side related to food, that is, not only the food itself but also the background, dishware, and light, depending on whether we want to encourage—to increase consumption—or discourage—to, for example, reduce the amount of food eaten for dietary purposes. The negative side of consuming and disposing of synthetic dyes and the health-promoting aspects of natural dyes are also mentioned, with the economic and environmental aspects of sourcing natural dyes being discussed. The food industry uses blue dyes not only for consumption, but also for food quality control, taking advantage of the pH-dependent colour change properties of the compound.

Agricultural droughts in South Africa, particularly in the Amahlathi Local Municipality (ALM), significantly impact socioeconomic activities, sustainable livelihoods, and ecosystem services, necessitating urgent attention to improved resilience and food security. The study assessed the interdecadal drought severity and duration in Amahlathi’s agricultural potential zone from 1989 to 2019 using various vegetation indicators. Landsat time series data were used to analyse the land surface temperature (LST), soil-adjusted vegetation index (SAVI), normalized difference vegetation index (NDVI), and standardized precipitation index (SPI). The study utilised GIS-based weighted overlay, multiple linear regression models, and Pearson’s correlation analysis to assess the correlations between LST, NDVI, SAVI, and SPI in response to the agricultural drought extent. The results reveal a consistent negative correlation between LST and NDVI in the ALM, with an increase in vegetation (R2 = 0.9889) and surface temperature. LST accuracy in dry areas increased to 55.8% in 2019, despite dense vegetation and a high average temperature of 40.12 °C, impacting water availability, agricultural land, and local ecosystems. The regression analysis shows a consistent negative correlation between LST and NDVI in the ALM from 1989 to 2019, with the correlation between vegetation and surface temperature increasing since 2019. The SAVI indicates a slight improvement in overall average vegetation health from 0.18 in 1989 to 0.25 in 2009, but a slight decrease to 0.21 in 2019. The SPI at 12 and 24 months indicates that drought severely impacted vegetation cover from 2014 to 2019, with notable recovery during improved wet periods in 1993, 2000, 2003, 2006, 2008, and 2013, possibly due to temporary drought relief. The findings can guide provincial drought monitoring and early warning programs, enhancing drought resilience, productivity, and sustainable livelihoods, especially in farming communities.

The regression analysis shows a consistent negative correlation between LST and NDVI in the ALM from 1989 to 2019, with the correlation between vegetation and surface temperature increasing since 2019. The SAVI indicates a slight improvement in overall average vegetation health from 0.18 in 1989 to 0.25 in 2009, but a slight decrease to 0.21 in 2019. The SPI at 12 and 24 months indicates that drought severely impacted vegetation cover from 2014 to 2019, with notable recovery during improved wet periods in 1993, 2000, 2003, 2006, 2008, and 2013, possibly due to temporary drought relief. The findings can guide provincial drought monitoring and early warning programs, enhancing drought resilience, productivity, and sustainable livelihoods, especially in farming communities.","PeriodicalId":22183,"journal":{"name":"Sustainability","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
In recent years, time series land cover products have been developed rapidly. However, the traditional classification strategy rarely considers time continuity and spatial consistency, which leads to the existence of unreasonable changes among the multi-period products. In order to solve the existing problems, this paper proposes a matrix decomposition model and an optimized hidden Markov model (HMM) to improve the consistency of the time series land cover maps. It also compares the results with the spatio-temporal window filtering model. The spatial weight information is introduced into the singular value decomposition (SVD) model, and the regression model is constructed by combining the eigenvalues and eigenvectors of the image to predict the unreasonable variable pixels and complete the construction of the matrix decomposition model. To solve the two problems of reliance on expert experience and lack of spatial relationships, this paper optimizes the model and proposes the HMM Land Cover Transition (HMM_LCT) model. The overall accuracy of the matrix decomposition model and the HMM_LCT model is 90.74% and 89.87%, respectively. It is found that the matrix decomposition model has a better effect on consistency adjustment than the HMM_LCT model. The matrix decomposition model can also adjust the land cover trajectory to better express the changing trend of surface objects. After consistent adjustment by the matrix decomposition model, the cumulative proportion of the first 15 types of land cover trajectories reached 99.47%, of which 83.01% were stable land classes that had not changed for three years.
