This study analyses the economics of conservation tillage (CT) with respect to its effect on maize yield and chemical fertiliser, herbicide, and female and male labour demand. We estimate production and input demand functions using seemingly unrelated regressions on plot‐level cross‐sectional farm household data collected in the north‐west of Ethiopia. A two‐step control function is applied to address potential endogeneity bias due to the inclusion of the CT adoption decision as an explanatory variable. Our results show that CT increases maize yield and chemical fertiliser demand. Additionally, the results show that the adoption of CT reduces female and male labour required for crop production. However, this is achieved through the increased use of herbicides, which might have an undesirable health and environmental effects.  相似文献

Distance functions are increasingly being augmented, with environmental goods treated as conventional outputs. A common approach to evaluate the opportunity cost of providing an environmental good is the exploitation of the distance function's dual relationship to the value function. This implies that the opportunity cost is assumed to be non‐negative. This approach also requires a convex technology set. Focusing on crop diversification for a balanced sample of 44 cereal farms in the East of England for the years 2007–2013, this paper develops a novel opportunity cost measure that does not depend on these strong assumptions. We find that the opportunity cost of crop diversification is negative for most farms.  相似文献

目前,员工过劳问题在我国企业发展中日益凸显,需要予以重视和解决。基于个体与组织互动角度,通过对338名企业员工的问卷调查分析职业延迟满足和职业成长机会对员工过劳的影响,并检验职业成长机会对职业延迟满足影响员工过劳的调节作用,结果表明:职业延迟满足的两个维度(工作延迟满足和职业生涯延迟满足)均对员工过劳有显著正向影响,而职业成长机会对员工过劳有显著负向影响;职业成长机会对职业延迟满足影响员工过劳具有负向调节作用,即职业成长机会越大,职业延迟满足与员工过劳的正向关系越弱。因此,企业管理者应合理引导和帮助员工做好职业生涯规划,为员工提供合适的多元化发展通道,以有效预防和缓解员工过劳。  相似文献

Payments for ecosystem services (PES) are environmental management tools that enable corporations to simultaneously enhance their environmental performance and fund sustainable development in rural areas. PES is primarily promoted as part of a sustainable production strategy for conserving natural resources, offsetting carbon emissions, and green supply chain management. Nevertheless, PES uptake by the private sector remains low, and few studies have analysed whether corporate‐financed PES schemes conform to this rationale. This study evaluates three of the first PES schemes in Thailand, financed by large corporations in the water utilities, aquaculture, and beverage sectors. Interviews with 39 business managers and project stakeholders suggest that PES may be viewed as a tool for philanthropy, public relations, and gaining license to operate—akin to many corporate social responsibility initiatives. Explanations and ramifications are discussed in the context of ecological uncertainty, risk management, financial performance, organisational learning, and the corporate‐engagement strategies of non‐governmental organisations.  相似文献

以中国2013年以来实行的碳排放交易试点政策作为准自然实验事件,基于2000-2017年中国30个省市的面板数据,运用双重差分法实证检验碳排放交易制度的节能减排效应及影响机制。研究发现,碳排放交易制度有利于实现中国经济“节能”与“减排”的双重目标,并通过了一系列稳健性检验;作用机制检验表明,能源效率提升和能源结构转型都是碳排放交易制度实现节能减排目标的重要路径;能源效率提升在碳排放交易制度实现“节能”和“减排”中分别发挥了10.19%和5.93%的作用,而能源结构转型分别发挥了48.87%和52.95%的作用。这意味着中国碳排放交易制度实现节能减排的主要动力来自能源结构转型,而非能源效率提升。能源结构转型涉及问题更加宏观和深层,这为中国加快推进节能减排进程,特别是完成2030年碳达峰和2060年碳中和的国际承诺提供政策启示。  相似文献

自然圣境是对人类具有特殊精神意义的自然区域,自然圣境除了具有精神文化价值,在生态环境保护方面也发挥了重要作用。自然圣境的生态保护功能主要体现在保护生态环境和自然资源以及为珍稀濒危物种提供栖息地。目前,因旅游和工程项目过度开发、土地利用变化、所属权转移、价值观念的变化和自然环境变迁等因素,造成自然圣境的生态保护功能面临挑战。面对这些问题,应加强对自然圣境及其生态保护功能的正确认知,将自然圣境纳入保护地和生态补偿体系当中,发挥自然圣境生态文化的灵魂作用,并制定与自然圣境保护相关的法律法规。  相似文献

With rapid increases in global food demand and production, oil palm expansion constitutes a major emerging challenge for forest conservation in Amazonia and other tropical forest regions. This threat is evident in the Peruvian Amazon, where local and national incentives for oil palm cultivation along with growing large-scale investments translate into accelerated oil palm expansion. Environmental sustainability of oil palm cultivation in the Peruvian Amazon is contingent on policy incentives for expansion onto already-cleared lands instead of biodiverse, high carbon primary rainforests. Previous research indicates that while industrial plantations use less land area than local smallholders, companies have a higher tendency to expand into primary rainforests. However, the motivations behind these differing expansion scenarios remain unclear. In this study we combine data from optical and radar satellite sensors with training information, field discussions, and review of public documents to examine the policy incentives and spatial patterns associated with oil palm expansion by smallholders and industries in one of Peru’s most rapidly changing Amazonian landscapes: the Ucayali region of the city of Pucallpa. Based on our satellite-based land cover change analysis, we found that between 2010 and 2016, smallholders utilized 21,070 ha more land area for oil palm than industries but industrial expansion occurred predominantly in old growth forests (70%) in contrast to degraded lands for smallholders (56%). Our analysis of national policies related to oil palm expansion reveal policy loopholes associated with Peru’s “best land use” classification system that allow for standing forests to undergo large-scale agricultural development with little government oversight. We conclude that both sectors will need careful, real-time monitoring and government engagement to reduce old-growth forest loss and develop successful strategies for mitigating future environmental impacts of oil palm expansion.  相似文献

Abstract

Despite the strong evidence for the beneficial influence of resilience for employee stress resistance in domestic settings, the construct has not received much attention in the expatriation literature, where stress is considered a major factor for expatriates’ poor cross-cultural adjustment and turnover. Drawing upon conservation of resources theory, the present study examines resilience as an antecedent of expatriate work adjustment and turnover intentions. Furthermore, this study investigates the moderating role of perceived organizational inclusion climate as a resource-protecting organizational factor. Results from a survey of 175 expatriates in South Korea indicate that resilience is positively related to expatriate work adjustment and that these positive effects are more pronounced when expatriates perceive their organizational climate to be highly inclusive. Furthermore, findings suggest that work adjustment mediates the effects of resilience on turnover intentions and that this mediation is moderated by a perceived organizational inclusion climate. Implications for theory and practice are discussed.  相似文献
