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 this paper we develop an equilibrium business-cycle model for an economy with both clean and dirty (polluting) plants. We conclude that the best time to implement cleaner production technologies is during a slowdown of the economy. Due to external effects and market failures the timing of pollution abatement investments is not expected to be optimal in the real world. We test the optimality of the timing of those investments with data for Germany, the Netherlands, and the USA. It appears that for more than 25 per cent of the sectors pollution abatement investments show significant counter-cyclical behaviour, while in 10 per cent of the sectors these investments are pro-cyclical. 相似文献

The question of whether, and to what extent, business managers have obligations to stakeholders has been the principal theme in much of recent business ethics literature. The question of whether shareholders have obligations to stakeholders, however, has not been addressed sufficiently. I provide some needed attention to this matter by examining the positions of shareholders in the contemporary world of investing. Their positions are considerably different than that often envisioned by business ethicists and economists where shareholders determine the directions of corporate activities through their voting decisions. Typical contemporary investors rarely control corporate activities. If they own corporate securities directly, generally they own too small an interest to exercise control. And, in most cases, they do not even own corporate securities directly, but, rather, own shares in funds. Because of the positions of shareholders today, it is highly questionable whether most have obligations to stakeholders. This has a significant implication for business managers. Whether or not shareholders have obligations to stakeholders, business managers have a greater obligation to educate shareholders about how corporate activities affect stakeholders. I provide a justification for that obligation and comment on how business managers might begin to fulfill it. 相似文献

Competitive small-dimension international trade models perform well in comparing free (or restrictive) trade with autarky,
especially in emphasizing that consumption patterns can differ from production patterns and that production becomes highly
concentrated while consumption patterns are expanded. Variations on these small-dimensional models can usefully show how with
trade production patterns may nonetheless be more diverse and a country’s labor force become more heterogeneous in its skills.
The paper illustrates how the Middle Products framework can be reinterpreted to support variety in production and in labor
skills.

Measuring the immeasurable — A survey of sustainability indices 总被引:1,自引:0,他引:1
Sustainability indices for countries provide a one-dimensional metric to valuate country-specific information on the three dimensions of sustainable development: economic, environmental, and social conditions. At the policy level, they suggest an unambiguous yardstick against which a country's development can be measured and even a cross-country comparison can be performed. This article reviews the explanatory power of various sustainability indices applied in policy practice. We show that these indices fail to fulfill fundamental scientific requirements making them rather useless if not misleading with respect to policy advice. 相似文献
