Bringing ecosystem services into economic decision-making: land use in the United Kingdom.

Landscapes generate a wide range of valuable ecosystem services, yet land-use decisions often ignore the value of these services. Using the example of the United Kingdom, we show the significance of land-use change not only for agricultural production but also for emissions and sequestration of greenhouse gases, open-access recreational visits, urban green space, and wild-species diversity. We use spatially explicit models in conjunction with valuation methods to estimate comparable economic values for these services, taking account of climate change impacts. We show that, although decisions that focus solely on agriculture reduce overall ecosystem service values, highly significant value increases can be obtained from targeted planning by incorporating all potential services and their values and that this approach also conserves wild-species diversity.

Environmental health implications of global climate change.

This paper reviews the background that has led to the now almost-universally held opinion in the scientific community that global climate change is occurring and is inescapably linked with anthropogenic activity. The potential implications to human health are considerable and very diverse. These include, for example, the increased direct impacts of heat and of rises in sea level, exacerbated air and water-borne harmful agents, and--associated with all the preceding--the emergence of environmental refugees. Vector-borne diseases, in particular those associated with blood-sucking arthropods such as mosquitoes, may be significantly impacted, including redistribution of some of those diseases to areas not previously affected. Responses to possible impending environmental and public health crises must involve political and socio-economic considerations, adding even greater complexity to what is already a difficult challenge. In some areas, adjustments to national and international public health practices and policies may be effective, at least in the short and medium terms. But in others, more drastic measures will be required. Environmental monitoring, in its widest sense, will play a significant role in the future management of the problem.

Rediscovering the medical school.

Medical schools, once devoted primarily to educating medical students, have evolved into complex academic medical centers (AMCs), some of which place a greater emphasis on research and the clinical business than on educating future physicians. This occurred primarily as the result of outside forces, specifically the available revenue streams that have fostered growth. Discipline-based departments have been at the center of the governance structure of medical schools, but many AMCs now have research institutes and centers to enhance research productivity, and faculty group practices to maximize clinical revenue. Although AMCs have been successful in making scientific discoveries, developing new technologies, and providing state-of-the-art clinical care, their successes have not always been favorable to the education mission. Furthermore, the roles of departments and their chairs have not always been carefully considered; a mismatch between organizational and governance structures is occurring. In this article several suggestions are offered to help medical schools rediscover their unique reason for existence and better distinguish core missions from core businesses. Mission-based management and mission-based budgeting provide the framework for maximum success of all the missions. Specific suggestions include (1) organizing a national task force to consider optimal organizational and governance structures of modern AMCs, (2) establishing a core teaching faculty, (3) creating a matrix letter of assignment that aligns salary rates with assigned activities, (4) linking education to the provision of health care to the underinsured, and (5) forming education centers to effectively centralize governance of the education mission.
