Many developing countries face a major challenge today: how to safeguard the biodiversity maintained in the fields of the rural poor - which constitute a national and global public good - whilst meeting those same people's development needs and rights? A solution to this dilemma has thus been sought in adapting the design and implementation of Payments for Ecosystem Services (PES) concepts to the conservation of agrobiodiversity.Here we review the application of nine such Payments for Agrobiodiversity Conservation (PACS) schemes that have been applied to date in four Latin American countries over the period 2010–2018. These covered 130 threatened varieties across a number of major food crops, and involved over 100 farming communities and 1,100 farmers (45 % of which were women). Conservation service offers were received through a competitive tender mechanism. Average bid offers revealed high heterogeneity, varying between US$675/ha. to ten times as much.In relation to issues identified as key to PES, such as spatial targeting, differentiated payments and conditionality, the underlying design of the PACS schemes may be considered solid. PACS-related prioritisation processes allow for the a priori identification of sites with high ecosystem service densities and high threat levels. The use of competitive tenders permits accounting for cost heterogeneity in the provision of conservation services and for payments to be differentiated. Conditionality is strong.In terms of implementation, a “back of the envelope” calculation based on the results of the competitive tenders suggests that conservation costs are modest. For a priority conservation portfolio of 100 varieties (which may be from different crops) each with a target area of five hectares, costs would amount to just under US$860,000 over twenty years or US$70,000 p.a. at a 5 % discount rate. The small-scale and one-off nature of the interventions realised to date, along with threatened crop variety seed availability constraints, have however meant that environmental effectiveness has been incomplete in the short-term (area cultivated with specific threatened varieties increased, but still below the “not at risk” threshold). The establishment of systematic monitoring systems is required to determine longer-term impacts and inform more regular PACS interventions within a dynamically evolving systems context.  相似文献

The core question addressed in the natural resource‐based view (NRBV) of the firm is how to develop and exploit resources beneficial for both the natural environment and firm performance. Due to the resource constraints and increased competition facing small manufacturing firms, achieving this is a challenge for such companies. Building on the NRBV and resource orchestration literatures, we examine the relationship between green purchasing capabilities (GPCs), CEO's environmental orientation (EO), and firm growth. Results from 304 Swedish small manufacturing firms indicate a significant relationship between GPC and growth, and this relationship is positively moderated by the EO of the CEO.  相似文献

This paper analyzes Milton Friedman's (1968a) article “The Role of Monetary Policy,” via a discussion of seven fallacies concerning the article. These fallacies are as follows: (i) “The Role of Monetary Policy” was Friedman's first public statement of the natural rate hypothesis. (ii) The Friedman–Phelps Phillips curve was already present in Samuelson and Solow's (1960) analysis. (iii) Friedman's specification of the Phillips curve was based on perfect competition and no nominal rigidities. (iv) Friedman's (1968a) account of monetary policy in the Great Depression contradicted the Monetary History’s version. (v) Friedman (1968a) stated that a monetary expansion will keep the unemployment rate and the real interest rate below their natural rates for two decades. (vi) The zero lower bound on nominal interest rates invalidates the natural rate hypothesis. (vii) Friedman's (1968a) treatment of an interest-rate peg was refuted by the rational expectations revolution. The discussion lays out the reasons why each of these seven items is a fallacy and infers key aspects of the framework underlying Friedman's (1968a) analysis.  相似文献

While the literature on business power and global finance has illuminated the ways in which financial institutions limit the policy autonomy of states in developing countries, we know much less about the circumstances under which the power of financiers is undermined. In this article, I advance explanations of these circumstances by arguing that state access to natural resource revenues reduces the power of financial institutions and enhances the capacity of the state to pursue central bank policies which violate the interests of major financiers. I employ a case study of central bank policy in Nigeria to probe this argument and find evidence that supports the claim that whenever the Nigerian government's access to resource revenues increased, the state's capacity to diverge from financiers’ preferred central bank policies and to advance its own preferences increased as well. The analysis provides the basis for broader propositions about the policy space of developing countries vis-à-vis financial institutions and the variability of structural power.  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

The research theorizes that environmental vulnerability can be minimized through mindfulness‐based strategies, and redesigning organizing processes, so that richer thinking is activated more quickly among greater number of people all of whom try to update their knowledge regardless of the knowledge source. It empirically evaluates the effects of organizational mindfulness and mindful organizing on resources and environmental sustainability. The model was tested in a very appropriate setting—Saudi Arabia, where increasing demand for and supply of energy culminates in unsustainable resources utilization and rise in greenhouse gas emissions and other environmental vulnerabilities. Data were collected from Saudi firms operating in the oil and gas sector and analyzed using SmartPLS software. The measurement and structural models were evaluated. The measurement model exhibits adequate model fit. The tests for the structural models show that four (of five) dimensions of organizational mindfulness (viz., commitment to resilience, deference to expertise, preoccupation with failure, and reluctance to simplify interpretations) and mindful organizing are significantly related at 5% significance level. Sensitivity to operations has no significant relationship with mindful organizing. Mindful organizing is significantly related to environmental and resources sustainability. Moreover, mindful organizing fully or partially mediates in the relationship between some of the dimensions of organizational mindfulness and environmental and resources sustainability. The study is one of the first to integrate mindfulness‐based approaches to sustainability and environmental research.  相似文献

文章构建了旅游业发展影响工业化的理论模型,并利用2000—2016年中国58个旅游城市面板数据和动态面板模型,从总体、专业化、规模和区域等多维度,分析检验了旅游业发展对城市工业化的影响及差异性。结果表明:无论是宏观层面,还是三种分类检验,旅游业发展对城市工业化都具有负向效应。当前,中国旅游城市存在一定的“旅游诅咒”效应,阻滞了其工业化深化;分专业化研究可知,旅游业发展对工业化的负向作用,由大到小依次为旅游高专业化、低专业化和半专业化城市;分规模研究发现,中型旅游城市的最显著,小型旅游城市次之,而大型旅游城市最不显著;分区域研究表明,中西部旅游城市的较突出,而东部旅游城市统计上并不显著。这为各个旅游城市采取有效措施及时防范和规避“旅游诅咒”效应和正确处理“旅游业+工业化”关系提供了参考依据。  相似文献

目前,农村金融消费者权益保护工作力量薄弱,自然灾害对农村金融消费者影响较大;同时,金融产品设计对农村金融消费者权益保护考虑不足。为保护农村金融消费者权益,并最大限度地规避自然灾害给农户带来的经济损失,应循序渐进、阶段性地推动金融消费立法,完善农村金融服务体系,构建农村金融消费者自然灾害权益保护机制,开展针对农村金融消费者的常态化宣传教育活动。  相似文献
