Managing agricultural floodplains to meet present and future human requirements without jeopardizing biodiversity conservation is a challenge for land use planners and ecologists. This paper aims to disentangle the relationships between ecosystem services and biodiversity in multifunctional landscapes, such as floodplain agroecosystems, by disaggregating their values across land use types. We measured eight ecosystem services (gas regulation, soil formation, nutrient regulation, habitat provision, food provision, raw materials production, education, and recreation) and six plant diversity indexes (richness, abundance, and true diversity for both plant species and growth forms) in seven land use types identified in the floodplain of the River Piedra (Spain). We observed that all land use types provided services to some extent, but each one was better at providing certain services. Natural or semi-natural habitats provided more services and hosted greater diversity than cultivated land use types. In addition, five diversity indexes were strongly correlated to at least three ecosystem services each one. Habitat provision and education were the ecosystem services positively correlating to most diversity indexes, whereas food provision was negatively correlated to all diversity indexes. Moreover, analyzing the interactions between ecosystem services and biodiversity across land use types, we observed that land use type was the controlling factor regarding the sign and significance of the interaction. The results of this study suggest that, in floodplains agroecosystems, a mosaic landscape of different land use types helps support ecosystem services and contributes to maintaining biodiversity while using local resources. Such land use policies might manage agricultural floodplains at the landscape scale while still being able to accommodate specific measures for each land use type. Moreover, riparian forests should be preserved and restored across the floodplain as they are hot spots for biodiversity and ecosystem services provision. 相似文献

A lenient product return policy represents the status quo of current return management practice in online retailing because it increases customers' order tendency. However, at the same time, many customers tend to return products under this policy, which incurs considerable costs for retailers. The present research introduces a keep reward (i.e., providing incentives to keep a product) as a new promotion strategy to improve the conventional lenient policy. Drawing on operant conditioning, the authors propose and test the reinforcing effect of a keep reward on customers' keep decision, compared to the conventional lenient policy. Results of a qualitative pilot study suggest that a keep reward is generally feasible in online retailing practice, especially in the low‐ to mid‐price segment and with rewards that are linked to future purchases. Two experimental studies verify the positive effect of a keep reward. Study 1 shows that it substantially increases keep intention compared to a conventional lenient policy. Study 2 shows that the effect on keep intention is moderated by customers' online shopping frequency, and this moderating effect is mediated by repurchase intention. In particular, the keep reward is most effective among frequent shoppers because they are more inclined to repurchase and thus, benefit from the reward. In summary, both studies support the keep reward as a valuable add‐on to the conventional lenient policy because order intention remains comparably high, while keep intention is higher. Theoretical implications and recommendations for online retailers on how to implement a keep reward in different industries are discussed. 相似文献

Differentiating regulation is a promising approach to agri-environmental regulation that may potentially reduce the environmental impact of agriculture at the lowest possible costs for the farmers and society, but also possesses a number of challenges. In this article, we explore the challenges to the legitimacy of agri-environmental regulation that occurs when the regulatory regime changes from general regulation to differentiated regulation. The analysis is based on a case study of the implementation of the Buffer zone act in Denmark – a regulation that prevents agricultural production in a 10 (later 9) meter fringe around selected waterbodies. We distinguish between two different ways of legitimizing: Producing knowledge and participation. We conclude that to harvest some of the obvious benefits of differentiated regulation a number of challenges must be resolved, 1) ensuring legitimacy of differentiated regulation is crucial, 2) differentiated regulation imply that farmers are also differentiated, 3) differentiated regulation implies new uncertainties, 4) the current knowledge regime need to be reconfigured, 5) stakeholders feel that they are unevenly treated and 6) it is difficult to establish a win–win solution for all farmers on an individual level. 相似文献

International institutions, including ‘global regimes’ and ‘regional regimes’, address an increasing number of environmental issues. While in the past much attention was given to global regimes, a plethora of regional institutions and organizations (regional regimes) and their environmental policies have recently gained more momentum in political practice and attention in scholarship. The Association of Southeast Asian Nations (ASEAN) is one such regime, and is actively developing its own policies relating to (e.g.) forests and the environment. These policies necessarily have to be useful for the regime’s member states; however, we further argue, that within the member states the regime’s policies especially have to be useful for specific member states’ bureaucracies, because it is they who actually develop the policies on behalf of the member states. Further, this paper aims to analyse the utility of ASEAN’s forest and environmental policy for specific member states and their responsible bureaucracies. Our analytical framework builds on regional regime theory, bureaucratic politics, and concepts of actor’s utility and interests. It differentiates the utility of the regional regime policies into several functions: (i) blocking unpleasant international initiatives, (ii) attracting international political or financial support, (iii) imposing rules on other member states, and (iv) aligning the interests of member states against external political opponents. Our results indicate that ASEAN’s environmental and forest policies serve all four functions. For instance, through ASEAN structures, Indonesia is blocking strict CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) regulation of ramin wood to maintain existing ramin protections and business, and the ASEAN Biodiversity Centre is found to be instrumental in blocking ambitious claims towards biodiversity from international actors. In addition, Malaysia and Singapore have imposed an ASEAN wildfire haze pollution agreement onto other member states in order to protect their directly affected interests in air quality and air traffic. ASEAN is also attracting to its members various international environmental funds in areas including climate change, community-based forestry, and sustainable peatland management. Last, member states under ASEAN actively align their positions in international climate negotiations as well as global forest deliberations to enhance their influence. We conclude that policies developed within regional regimes such as ASEAN are aligned with the interests of stronger member states, and their bureaucracies in particular. It remains unclear, however, how powerful these actors need to be in order to make this customization of regime policies valid for them. The results suggest that not only a potential hegemon, but also second or third powers may have this option. At the same time, member states’ activities do not seem to be conducted by states as unitary actors; instead, issue-specific actions are based on the interests of issue-relevant bureaucracies, which are in charge of representing a given member state in a given field of a regime’s policy. 相似文献

Intensive dairy farming has substantial impacts on freshwater and terrestrial ecosystems. Determining how to mitigate them while increasing production is driving the quest for sustainable milk production internationally. Green infrastructure (G.I.) provides private and public ecosystem services, including mitigation of farming environmental impacts. However, there are implementation barriers among farmers. New Zealand government supports farmer self-regulation as long as farmers meet environmental targets. Farmers are neither compensated for reducing environmental impacts, nor for setting aside G.I. in support of nature conservation. Dairy companies are under increasing pressure to ensure socially acceptable milk production practices among farmer suppliers. They may play a role in encouraging farmers to implement G.I. as a way of helping farmers meet regulatory compliance, and best farming practice. Using a content analysis of company policies, the role of dairy companies in encouraging G.I. among farmers is explored. Results indicate companies are concerned about the effects, and perception, of poor environmental farming practices on their profitability, and have developed some riparian G.I. policies, with government and farmer support. However, policies are farm-focused and are limited to one year, and thus lack the capacity to encourage G.I. in support of key ecosystem services, such as water cleansing and support for indigenous biodiversity that require landscape scaled networks and longer periods. Even at the farm scale, a majority of companies lack policies that encourage significant G.I. networks. Policies suggest companies, and by extension farmers, lack sufficient motivation to protect or restore them voluntarily. Under these conditions, significant G.I. is unlikely to develop under self-regulation, unless supplemented through motivating government stewardship payments. 相似文献

Due to their diversity and voluntariness, agri-environmental measures (AEMs) are among the Common Agricultural Policy instruments that are most difficult to assess. We provide an EU-wide analysis of AEM adoption and farm’s total AEM support over total Utilised Agricultural Area using a Heckman sample selection approach and single farm data. Our analysis covers 22 Member States over the 2000–2009 period, assesses the entire portfolio of AEMs and focuses on the relationship between AEM participation and farming system. Results show that participation in AEMs is more likely in less intensive production systems, where, however, per committed hectare AEM premiums tend to be lower. Member States group into three categories: high/low intensity farming systems with low/high AEM enrollment rates, respectively, and large high diversity countries with medium AEM enrollment rates. 相似文献

We develop a macroeconomic model in which the balance sheet condition of financial institutions plays an important role in the determination of asset prices and economic activity. The financial intermediaries in our model are required to make investment commitments before a complete resolution of idiosyncratic funding risk that can be addressed only by costly refinancing, forcing them to behave in a risk-averse manner. The model shows that the balance sheet condition of intermediaries can drive asset values away from their fundamentals, causing aggregate investment and output to respond to shocks to intermediaries. We use this model to evaluate several public policies designed to address balance sheet problems at financial institutions. With regard to short-run policies, we find that capital injections conditioned upon voluntary recapitalization can be a more effective tool than asset purchases. With regard to long-run policies, we demonstrate that higher capital requirements can have sizable short-run effects on economic activity, and that a long transition period helps avoid undesirable side effects. Finally, we show that the marginal effects of policies can be larger during “crises” because of the nonlinear interactions between some financial frictions and policy actions. 相似文献

In this paper we study the effectiveness of different types of cohesion policies with respect to convergence of regions. A two-region agent-based macroeconomic model is used to analyze short-, medium- and long-term effects of policies improving human capital and fostering adoption of technologies in lagging regions. With fully integrated labor markets the human capital policy positively affects the economically stronger region but reduces production in the targeted weaker region. Subsidies for high technology investment in the weaker region have a positive local output effect and a negative effect on the neighboring region, thereby fostering convergence. When labor markets are not integrated both policies support convergence. 相似文献
