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

As the flow of financial aid from the industrial countries may be expected to shrink rapidly as a consequence of their economic difficulties, the developing countries will have to find out possibilities of using their own financial resources more effectively. In this connection the task of modernizing their financial institutions should not be neglected. 相似文献

UK GAAP has traditionally allowed the write-off of purchased goodwill directly to reserves, resulting in the widespread depletion of book equity. Companies have also been permitted to revalue fixed assets at management's discretion. This study examines whether upward revaluations have been associated with the depletion of book equity and with other costly contracting explanations identified in prior research. Our results provide strong support for the equity depletion hypothesis, both with regard to the decision to revalue and the timing of the revaluations. Indebtedness, liquidity, size and fixed asset intensity are also consistently associated with upward revaluation. 相似文献

Since most agricultural programs employ two or more policy instruments simultaneously, it is notable thai little research has attempted to find optimal instrument combinations and no research exists which evaluates the social costs (unrealized benefits) of combining instruments suboptimally. In our paper we report a simple and feasible method to find optimal policy instrument combinations, and we provide the first general, formal approach to measuring the social costs of suboptimal policy instrument combinations. Our approach is illustrated in an analysis for live major U.S. crops (corn, feed grains, wheat, rice, cotton). The simple model we employ for the illustration suggests that except lor the feed grains program, the observed programs combined policy instruments quite suboptimally. We conclude that agricultural economics research now can and should begin placing increased emphasis on studying optimal policy instrument combinations. 相似文献

As the issue of marketing's social responsibility grows in significance, the topic of materialism surfaces. While many marketing efforts encourage materialism, the materialism that is encouraged may have negative societal effects. An understanding of the effects of materialism on individuals, families, society, etc., is important in evaluating whether or not it is socially irresponsible for marketers to encourage materialism. However, the adequate empirical work has not yet been done on the overall effects of materialism. The current paper asks and addresses one important empirical question in this area. Do consumers who are more materialistic have different ethical standards than those who are not? Empirical evidence is presented which would indicate that materialism is negatively correlated with people's higher ethical standards as consumers. The implications for this in understanding social responsibility are discussed. 相似文献
