Environmental concern and the stringent regulations of the construction sector are leading to increasing pressure for the adoption of sustainable practices; however, this is accompanied by technical, operational, and organizational challenges. Little is known about how these factors, taken together, affect implementation effectiveness. Through the first empirical validation of Sustainable Construction Integration Theory (SCIT), this study examines the complex dynamics between the technical, operational, and organizational layers of sustainable construction. Through structural equation modeling with thematic analysis of 429 building projects, this research demonstrates HRC and Performance (β = 0.38, p < 0.001) interactions, as well as the critical moderating role of organizational commitment and support (OCS). The second finding indicates that HRC acts as a mediator between technical and operational characteristics and the outcomes of implementation (Q2 = 0.695). The results also show that energy efficiency has a big effect on how sustainable a project is (β = 0.42, p < 0.001), and that capacity and organizational barriers are very important things to think about when putting the plan into action, as they cause 16 % of implementation problems. This study leverages institutional theory and the dynamic capacity framework to demonstrate that SCIT enhances the implementation success rate by 38 percent. These insights contribute to practical guidelines for sustainable construction organizations that emphasize combined human resource development and robust organizational support for sustainable outcomes.

对环境的关注和建筑行业严格的规章制度导致采用可持续做法的压力越来越大；然而，这伴随着技术、操作和组织方面的挑战。对于这些因素加在一起如何影响执行效力，人们知之甚少。通过对可持续建设整合理论（SCIT）的首次实证验证，本研究考察了可持续建设的技术、运营和组织层面之间的复杂动态关系。通过对429个建筑项目的结构方程建模和专题分析，本研究证明了HRC与绩效(β = 0.38, p <；0.001)的相互作用，以及组织承诺和支持（OCS）的关键调节作用。第二个发现表明，HRC在技术和操作特征与实施结果之间起中介作用（Q2 = 0.695）。结果还表明，能源效率对项目的可持续性有很大影响(β = 0.42, p <；0.001)，并且在将计划付诸行动时，能力和组织障碍是需要考虑的非常重要的事情，因为它们导致了16%的实施问题。本研究利用制度理论和动态能力框架证明，工商和科技可使实施成功率提高38%。这些见解为可持续建筑组织提供了实用的指导方针，强调人力资源开发的结合和对可持续成果的强有力的组织支持。

Fruit peels that are usually discarded as agricultural residues serve as a rich source of various nutrients, such as carbohydrates, proteins, vitamins, and minerals, necessary for the growth and development of any fish. Moreover, their low cost and available nutritional composition provide a solution for resource limitations and waste disposal issues, and they can also be used as a cheap and green substitute for conventional fish diets. Several researchers have pointed out that fruit peel waste is an acceptable culture feed resource for aquatic animals, especially tilapia catfish and carp fish. This improves the growth performance of the fish, feed utilization efficiency, and their well-being in general. Furthermore, utilizing fruit peel waste is also favorable in meeting sustainable development goals by improving food security, environmental protection, and resource efficiency in aquafeed production. Advances in technology are also necessary if the solution is to be widely accepted. This includes nutritional diversity, processing methods, politics, and public opinion. More research is needed, as well as studies to optimize processing methods for assessment of nutritional value and acceptance of fruit peel waste in aquafeed formulations for the development of the aquaculture sector without putting a toll on the environment.

通常作为农业残留物丢弃的果皮是各种营养物质的丰富来源，如碳水化合物、蛋白质、维生素和矿物质，是任何鱼类生长发育所必需的。此外，它们的低成本和可用的营养成分为资源限制和废物处理问题提供了解决办法，它们也可以用作传统鱼类饲料的廉价和绿色替代品。一些研究人员指出，果皮废料是水生动物，特别是罗非鱼、鲶鱼和鲤鱼可接受的养殖饲料资源。这提高了鱼类的生长性能、饲料利用效率和总体健康状况。此外，利用果皮废弃物也有利于实现可持续发展目标，提高水产饲料生产的粮食安全、环境保护和资源效率。如果解决方案被广泛接受，技术进步也是必要的。这包括营养多样性、加工方法、政治和公众舆论。需要进行更多的研究，以及研究如何优化加工方法，以评估营养价值，并在不损害环境的情况下将果皮废料纳入饲料配方，从而促进水产养殖部门的发展。

Access to clean water and sanitation is a fundamental requirement for sustainable development. However, many low and middle income countries, such as India, continues to face significant challenges in achieving Sustainable Development Goal 6 (SDG 6), i.e., access to clean water and sanitation. Despite enormous initiatives taken by India, issues such as groundwater depletion, water pollution, and sanitation gaps persist. Population growth, urbanisation, and industrial expansion have put pressure on water resources, reducing water quality and sanitation services. This paper assesses the key barriers and drivers influencing India’s efforts and on the way forward to achieve the global 2030 Agenda. The present study follows the PRISMA methodology approach, combining secondary data, policy reviews, case studies, and government reports to assess the progress, barriers, and future outlook for SDG 6 in India. The key findings revealed that India's major drivers to SDG 6 are substantial progress in toilet construction,water supply expansion through government missions, technological breakthrough, public awareness campaigns, and public-private partnerships. Key barriers to achieve SDG 6 include inadequate wastewater treatment capacity, over-extraction of groundwater, rapid population growth, the adverse effects of climate change on water availability and sanitation infrastructure. Strengthening regional institutions, developing climate-resilient infrastructure, and innovative financing models could accelerate progress towards SDG 6. Additionally, the study recommends water and sanitation courses in the school curriculum and policy reforms, could help in realizing SDG 6 by 2030.

获得清洁用水和卫生设施是可持续发展的一项基本要求。然而，许多低收入和中等收入国家，如印度，在实现可持续发展目标6（可持续发展目标6），即获得清洁水和卫生设施方面继续面临重大挑战。尽管印度采取了巨大的举措，但地下水枯竭、水污染和卫生差距等问题仍然存在。人口增长、城市化和工业扩张给水资源带来了压力，降低了水质和卫生服务。本文评估了影响印度努力和实现《2030年全球议程》前进道路的主要障碍和驱动因素。本研究采用PRISMA方法，结合二手数据、政策审查、案例研究和政府报告，评估印度可持续发展目标6的进展、障碍和未来前景。主要调查结果显示，印度实现可持续发展目标6的主要推动力是厕所建设方面的实质性进展、通过政府任务扩大供水、技术突破、公众意识运动和公私合作伙伴关系。实现可持续发展目标6的主要障碍包括废水处理能力不足、地下水过度开采、人口快速增长、气候变化对供水和卫生基础设施的不利影响。加强区域机构、发展气候适应型基础设施和创新融资模式可以加快实现可持续发展目标6的进程。此外，该研究建议在学校课程和政策改革中加入水和卫生课程，有助于到2030年实现可持续发展目标6。

While scholars have explored the dynamics of African border communities focusing on context-specific everyday practices of crime prevention and safer neighbourhood strategies, attention is often directed to community policing than other strategies. Relatively little attention has been dedicated to exploring how sustainable and fair development practices can make neighbourhoods safer. This study aimed to address this gap by exploring how sustainable and fair development practices intersect to prevent crime and encourage the emergence of safer neighbourhoods. The study employed a qualitative methodology where fifty participants were purposively selected to take part in the study due to their expert insights on community policing and sustainable development practices. Data for the study were gathered through key stakeholder interviews and focus group discussions with security operatives, household heads, youth leaders, and chiefs in the border community of Paga. To link sustainable development practices and safer neighbourhoods, the study looked at both international conversations about preventing crime and making neighbourhoods safe, as well as local discourses about crime and making a living. Youth employment, equitable access to common resources, education, skills development, environmental protection, and equal opportunities within communities, demonstrated the ability to make criminal activities less attractive, thus, prompting the emergence of safer neighbourhoods. The study argues that when individuals are offered decent livelihoods and feel well integrated in their communities, they are less likely to engage in criminal activities. The findings of the study contribute to the broader literature on crime prevention and safer neighbourhood by introducing an economic and social sustainable dimension. The findings, thus, inform the development and implementation of youth empowerment initiatives in border communities and other contexts in Ghana and Africa for effective crime prevention and community safety.

虽然学者们已经探索了非洲边境社区的动态，重点关注具体情况的日常预防犯罪实践和更安全的社区战略，但注意力往往指向社区警务，而不是其他战略。相对而言，很少有人关注可持续和公平的发展实践如何使社区更安全。本研究旨在通过探索可持续发展和公平发展如何相互交叉以预防犯罪和鼓励更安全社区的出现来解决这一差距。该研究采用了定性方法，其中有目的地选择50名参与者参加研究，因为他们对社区警务和可持续发展实践有专业见解。该研究的数据是通过对关键利益相关者的访谈和与Paga边境社区的安全人员、户主、青年领袖和酋长的焦点小组讨论收集的。为了将可持续发展实践与更安全的社区联系起来，该研究既研究了关于预防犯罪和使社区安全的国际对话，也研究了关于犯罪和谋生的地方话语。青年就业、公平获得公共资源、教育、技能发展、环境保护以及社区内的平等机会，证明了降低犯罪活动吸引力的能力，从而促使更安全社区的出现。该研究认为，当个人获得体面的生计并感觉很好地融入社区时，他们参与犯罪活动的可能性就会降低。该研究的结果通过引入经济和社会可持续的维度，为预防犯罪和更安全的社区提供了更广泛的文献。因此，调查结果为在加纳和非洲的边境社区和其他情况下制定和执行青年赋权倡议提供了参考，以有效预防犯罪和保障社区安全。

The Colombian government is promoting the transition to electric vehicles in metropolitan areas; however, a lack of decision-making in intermediate and small cities hinders local sustainable objectives. The transition to clean technologies must be aligned with the realities intrinsic to cities. Therefore, a holistic methodology to quantify the social acceptance of sustainable transport technologies in intermediate cities is proposed, through an AHP (Analytical Hierarchy Process) model integrating four dimensions: technical, economic, environmental, and social. In the absence of local experience with low-emission vehicles, simulations were carried out in SUMO (Simulation of Urban Mobility) to evaluate Internal Combustion Engine Vehicle (ICEV), Electric Vehicle (EV), Plug-in Hybrid Electric Vehicle (PHEV), and Natural Gas Vehicles (NGV), considering the dynamics of individual public transport mode in the city under study (Pasto, Colombia). Five criteria were selected: energy consumption, autonomy, accumulated cost, government incentives, and life-cycle greenhouse gas emissions. The results show that NGV obtained the highest social acceptance rating, mainly due to its cost-effectiveness and infrastructure reliability under economic and technical dimensions. Prioritizing environmental factors improved EV scores, but infrastructure and financial constraints continue to limit their uptake. Evaluation robustness was enhanced by the AHP-TOPSIS approach. As institutional capacity and infrastructure advance, NGV seems to be a promising transition technology that will allow for a gradual switch to EVs. This research presents an approach adapted to contexts with limited experience in low-emission technologies, contributing to the sustainable modernization of individual public transport.

哥伦比亚政府正在推动大都市地区向电动汽车过渡；然而，中小城市缺乏决策，阻碍了地方可持续发展目标的实现。向清洁技术的过渡必须与城市固有的现实保持一致。因此，本文提出了一种综合技术、经济、环境和社会四个维度的AHP模型来量化中等城市可持续交通技术的社会接受度的整体方法。在缺乏当地低排放车辆经验的情况下，在SUMO（城市交通模拟）中进行了模拟，以评估内燃机汽车（ICEV），电动汽车（EV），插电式混合动力汽车（PHEV）和天然气汽车（NGV），考虑到所研究城市（哥伦比亚帕斯托）的各个公共交通模式的动态。选择了5个标准：能源消耗、自主性、累积成本、政府奖励、生命周期温室气体排放。结果表明，NGV获得了最高的社会接受度，主要是由于其经济和技术维度下的成本效益和基础设施可靠性。优先考虑环境因素提高了电动汽车的得分，但基础设施和财政限制仍然限制了它们的采用。采用AHP-TOPSIS方法增强了评价的稳健性。随着机构能力和基础设施的发展，天然气车似乎是一种有前途的过渡技术，它将允许逐步转向电动汽车。本研究提出了一种适合低排放技术经验有限的情况的方法，有助于个人公共交通的可持续现代化。

The entire coastal Bangladesh faces significant challenges in maintaining a consistent supply of freshwater due to salinity intrusion and various climatic hazards. This study aimed to assess the sources, consumption patterns, and challenges in freshwater management across three coastal villages. Bagerhat, Khulna and Satkhira Districts were purposively selected based on their proximity to the coastline, categorized as shoreline, interim, and inland areas. Total 338 households were surveyed using simple random sampling to gather data through self-determined questionnaires. Additionally, three group discussions (GDs) and sixteen key informant interviews (KIIs) were conducted to explore the challenges and possible solutions. In the shoreline area, most respondents primarily utilized pond sand filter (PSF) water during the winter and rainwater in the rainy season for drinking purposes. In contrast, inland respondents relied on tube-wells and sono arsenic filter (SAF) water in the winter and rainwater during the rainy season. Furthermore, tube-wells were the predominant source used in the interim area during both seasons. The mean water consumption pattern exhibited an upward trend from winter to rainy season. The mean duration of the freshwater crisis was found to increase from the shoreline to inland area, showing shoreline (24.62)>interim (23.59)> inland (16.57). The trend of mean weighted average index (WAI) indicating sources of pollution was higher in the inland area (0.409) compared to the interim (0.389) and shoreline (0.365) area. The study recommends that immediate measures will be taken to ensure continuous access to freshwater, as the crisis is likely to worsen in the near future.

由于盐度入侵和各种气候灾害，整个孟加拉国沿海地区在维持持续的淡水供应方面面临重大挑战。本研究旨在评估三个沿海村庄淡水资源的来源、消费模式和面临的挑战。Bagerhat、Khulna和Satkhira地区是根据其与海岸线的接近程度有目的地选择的，分为海岸线、临时地区和内陆地区。采用简单随机抽样的方式对338户家庭进行调查，通过自主问卷收集数据。此外，进行了三次小组讨论（GDs）和16次关键信息者访谈（KIIs），以探讨挑战和可能的解决方案。在海岸线地区，大多数受访者在冬季主要利用池塘砂过滤器（PSF）水，在雨季主要利用雨水作为饮用目的。相比之下，内陆受访者在冬季依赖管井和sono砷过滤器（SAF）水，在雨季依赖雨水。此外，在这两个季节，管井是过渡地区使用的主要来源。平均耗水量从冬季到雨季呈上升趋势。淡水危机的平均持续时间由岸线向内陆地区依次增加，表现为岸线（24.62）>；内陆(16.57)。指示污染源的平均加权平均指数（WAI）在内陆地区（0.409）高于中部地区（0.389）和沿海地区（0.365）。该研究建议，应立即采取措施，确保持续获得淡水，因为危机可能在不久的将来恶化。

This study was conducted to examine the presence and empirical validity of the link between on-farm entrepreneurship and crop productivity in KwaZulu-Natal, South Africa. A sample of 221 smallholder farmers was drawn from Ndumo-B and Makhathini Irrigation Schemes, Jozini Local Municipality. Principal component analysis was employed to estimate a continuum proxy for on-farm entrepreneurship. Gross margin analysis, Cobb-Douglas production analysis, and the one-limit Tobit model were used to analyze the link between crop productivity and on-farm entrepreneurship. Compared to independent irrigators with better entrepreneurial attributes, scheme irrigators were found to have the lowest levels of entrepreneurial competency, followed closely by community gardeners. Due to the freedom they enjoy in making their own decisions, independent irrigators were more entrepreneurial, unlike scheme irrigators, where decisions are made collectively, free-riding behaviour is rampant, and incentive challenges are prevalent. The productivity of cabbages was found to increase at an increasing rate as farmer entrepreneurship increased. The study recommends that future training focus not only on entrepreneurial skills but also on entrepreneurial mindset and collective marketing of agricultural products. Future on-farm entrepreneurial development pathways should be planned, accounting for the heterogeneity and complexity of their farming systems.

本研究旨在检验南非夸祖鲁-纳塔尔省农场创业与作物生产力之间联系的存在性和实证有效性。从Jozini地方自治市的Ndumo-B和Makhathini灌溉计划抽取了221名小农样本。采用主成分分析来估计农场创业的连续代理。采用毛利率分析、柯布-道格拉斯生产分析和单限Tobit模型分析作物生产率与农场创业之间的关系。与具有更好创业属性的独立灌溉者相比，计划灌溉者的创业能力水平最低，紧随其后的是社区园丁。由于独立灌溉者享有自主决策的自由，他们更具有企业家精神，而不像计划灌溉者那样集体决策，搭便车行为猖獗，激励挑战普遍存在。研究发现，随着农民创业精神的增加，卷心菜的生产力也在以越来越快的速度增长。研究建议，未来的培训不仅要注重创业技能，还要注重创业心态和农产品集体营销。考虑到农业系统的异质性和复杂性，应规划未来的农场创业发展路径。

This paper investigates the socio-economic and the energy changes that have taken place in six developing countries characterized by established tourism economies. By considering the years 2000 and 2021, the MuSIASEM approach is used to analyse the energy allocation and use that have taken place in Cuba, Dominic Republic, Jamaica, Jordan, Malaysia, and Tunisia. Results show that for all the countries the percentage variation of GDP has been higher than the energy consumption increase, denoting efficiency improvements across all the sectors, with exception of the service compartment of Tunisia and Jamaica. Tunisia has also been the only country to increase the exosomatic metabolic rate of the household and the paid sectors, denoting an energy consumption rise per unit of human time. All the areas have increased the percentage contribution of the service sector to employment and GDP generation. Given the extensive role that tourism activities are playing in these countries, further analysis should be devoted to investigating alterative development approaches and the related sustainability goals.

本文研究了六个以旅游经济为特征的发展中国家的社会经济和能源变化。通过考虑2000年和2021年，MuSIASEM方法用于分析古巴、多米尼克共和国、牙买加、约旦、马来西亚和突尼斯的能源分配和使用情况。结果表明，对于所有国家，GDP的百分比变化都高于能源消耗的增长，这表明除了突尼斯和牙买加的服务部门之外，所有部门的效率都有所提高。突尼斯也是唯一一个提高家庭和有偿部门的体外代谢率的国家，这表明每单位人类时间的能源消耗增加了。所有这些领域都提高了服务业对就业和国内生产总值的贡献百分比。鉴于旅游活动在这些国家所发挥的广泛作用，应进一步分析以调查其他发展办法和有关的可持续性目标。

Current trends in urbanization and climate change in many arid and semi-arid countries across sub-Saharan Africa are threatening the sustainability of Urban and Peri-urban Agriculture (UPA) and food systems due to rapidly growing competition for scarce resources such as water and land. Water scarcity in the sub-region is currently recognized as a multidimensional problem, affecting urban farm productivity, food safety, food security and poverty, as well as public health systems. The use of treated or untreated municipal wastewater (MWW) in agriculture has increasingly become a relevant option for freshwater conservation, optimizing the agronomic and economic gains, and increasing urban food security and nutrition. This study investigates empirically the link between MWW use and productivity of vegetable farmers in Ouagadougou, Burkina Faso. Using survey data from 416 vegetable farmers, we employed a semi-log production function augmented with an endogenous binary-treatment effect equation to estimate the drivers and impact of MWW use on value of vegetable output, accounting for selection bias and omitted variable problem. We find that MWW use alone is associated with higher value of vegetable output. However, regulation through contacts with extension agents reduces the agronomic and economic benefits of using MWW for irrigation. This study proposes a provision of small but efficient wastewater treatment technologies with the support of extension agents and a redesign of extension education that promotes safer MWW use to maximize its productivity benefits for all farmers. We also suggest that future research should explore the long-term impact of MWW use on soil health and the effect of extension education content and mode of delivery on vegetable production.

撒哈拉以南非洲许多干旱和半干旱国家当前的城市化和气候变化趋势正威胁着城市和城郊农业（UPA）和粮食系统的可持续性，原因是对水和土地等稀缺资源的竞争日益激烈。该分区域的缺水目前被认为是一个多方面的问题，影响到城市农业生产力、食品安全、粮食安全和贫困以及公共卫生系统。在农业中使用经过处理或未经处理的城市废水已日益成为保护淡水、优化农业和经济收益以及增加城市粮食安全和营养的相关选择。本研究对布基纳法索瓦加杜古菜农的MWW利用与生产力之间的联系进行了实证调查。利用416个菜农的调查数据，在考虑选择偏差和遗漏变量问题的情况下，我们采用了一个半对数生产函数和内源性二元处理效应方程来估计MWW使用对蔬菜产值的驱动因素和影响。我们发现，仅MWW的利用就与更高的蔬菜产出价值相关。然而，通过与推广机构的联系进行管理降低了利用水能灌溉的农艺和经济效益。本研究建议在推广机构的支持下提供小型但高效的废水处理技术，并重新设计推广教育，以促进更安全的MWW使用，使其对所有农民的生产力效益最大化。未来的研究应进一步探讨水肥利用对土壤健康的长期影响，以及推广教育内容和实施方式对蔬菜生产的影响。
