Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.  相似文献

In India, cane is processed into sugar by cooperatives, public enterprises, and private (for‐profit) firms. The Indian government sets a unique floor price for each processor that is increasing in the firm's effectiveness in converting cane into sugar. The floor price binds for public and private firms but not for cooperatives, which rebate profits to members. We argue that this price floor policy creates a disincentive for private and public firms to be technically efficient in converting cane to sugar. In support of this hypothesis an analysis of 593 Indian sugar factories from 1992 to 2007 reveals statistically significant differences in technical efficiency, with cooperatives being the most efficient and public firms least efficient. We estimate welfare losses due to the technical inefficiency attributable to the price‐floor policy and argue that it can be eliminated by enacting policy to base price floors upon quality of the cane input received by a factory.  相似文献

To Steal or Not to Steal: Firm Attributes, Legal Environment, and Valuation   总被引:22,自引:1,他引:22  
Data on corporate governance and disclosure practices reveal wide within‐country variation that decreases with the strength of investors' legal protection. A simple model identifies three firm attributes related to that variation: investment opportunities, external financing, and ownership structure. Using firm‐level governance and transparency data from 27 countries, we find that all three firm attributes are related to the quality of governance and disclosure practices, and firms with higher governance and transparency rankings are valued higher in stock markets. All relations are stronger in less investor‐friendly countries, demonstrating that firms adapt to poor legal environments to establish efficient governance practices.  相似文献

This paper considers the methodological approaches to measuring the sustainability of development of socioecological and economic systems. It presents the results from assessing the sustainability of development of the Russian Federation in 2005–2011 using the suggested system of dynamic indicators, in which different private dynamic characteristics of the economic, ecological, and social development components are in a certain subordinate order.  相似文献

National banking systems around the world are subject to disruption through the failure of a single institution. To lessen this risk, regulations governing bank definition, capital adequacy, overdraft operations, and asset securitization are needed. This article reports on these four issues and concludes that (1) the definition of a bank varies widely between nations; (2) some central banks do not require that sufficient capital be maintained to attenuate the effect of internal or external shocks; (3) overdraft operations, where allowed, often result in a high degree of system risk; and (4) off-balance sheet financing operations may not be as risky as first was reported.  相似文献

Abstract: In this paper we propose that historically generated institutions and persistent pattern of human capital formation condition the emergent systems of innovation in Africa. These factors determine the development path of the region. We advance the notion of dynamic and non‐dynamic systems of innovation, the latter describing the African condition. We combine the strands of literature on institutions and their persistence in shaping development with evolutionary theory and systems of innovation. Evidence is presented on the colonial origins of skewed schooling enrolment, at variance with the industrialization objective of modern economies. Employing simple statistical tests, the persistence of initial human capital (school enrolment) reflects in the significant correlation among the three levels of schooling enrolments, and correlation of enrolment in 1970 with per capita income in 2000, a periodicity of some three decades. This outcome is consistent with the literature on countries at early stages of development. Path‐dependency is partially proved even though we did not attempt to investigate all variables making up the system of innovation. This is a first tentative attempt to explore long‐run development in Africa within the systems of innovation framework.  相似文献

We examine the dynamics of output connectedness of Asian Pacific Economic Cooperation (APEC) economies using time‐varying, region‐specific, generalised connectedness measures. We find that the connectedness of APEC economies with the rest of the world is quite substantial, with the 2008–09 Global Financial Crisis increasing the connectedness measures above their precrisis levels. The USA, China, and Korea are shown to be systemically important and to dominate APEC’s real activities, while outside the APEC region the roles of India and the UK are also non‐negligible. These results suggest that the majority of APEC economies are considerably open to output shocks from the dominant economies such that policymakers in APEC must be continuously conscious of headwinds originating from these sources.  相似文献
