This chapter, the longest in the book, explains the fundamentals of microeconomics and its application to the analysis of health and healthcare. The concepts of scarcity and opportunity costs lie at the heart of the economics discipline. Based on the standard production function with two input factors, the important concept of cost-efficiency is explained; and based on the premise of scarcity in the availability of input factors, the concept of opportunity costs is explained. An important insight from consumer theory is that people make trade-offs. Their preferences and income determine their chosen combination of goods, as illustrated by an indifference curve. An important piece of information for policymakers attempting to intervene in people’s demand for healthy, and unhealthy, goods is to know how sensitive demand is to changing prices and income. The chapter explains and defines elasticities of demand.

This chapter investigates whether the growing enthusiasm for ecosystem services recently expressed by conservation NGOs and international institutions is supported by evidence. Ecosystem services—the benefits humans receive from nature—have become the darlings of conservation on the assumption that the valuation of selected services may justify protecting land. A critical examination of a random sample of monetary valuations for regulating ecosystem services such as pollution treatment, finds that only onethird can be considered reliable, and that only ten percent of monetary value estimates can be transferred to other contexts. This suggests that the overall evidence base for assigning monetary value to nature is limited. Furthermore, diminishing returns, high opportunity costs, and technological substitutes might limit the amount of conservation that can be justified on the basis financial assessments of ecosystem services. As such, this chapter concludes that ecosystem services as a conservation strategy should not be embraced uncritically.

Ecological management based on the ecosystem approach promotes ecological protection and the sustainable use of natural resources. We developed a quantitative approach to identify the ecological function zones at the country-scale, through integrating supply and demand of ecosystem services. We selected the biologically diverse hotspot of Baoxing County, which forms a part of the Sichuan Giant Panda World Heritage Site, to explore the integration of ecosystem services supply and demand for ecosystem management. Specifically, we assessed the various support, provision, regulating, and cultural services as classified by the Millennium Ecosystem Assessment. We applied the InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) model to spatially map habitat quality, water retention, and carbon sinks, and used statistical data to evaluate food products, animal husbandry, and product supply services. We then quantified the demands for these services in terms of population, protected species, hydropower, water, and land use. The relationship between areas of supply and areas of demand was discussed for each township, and the spatial variability in the supply–demand relationship was also considered. As a result, we spatially divided the county into six ecological functional areas, and the linkages between each region were comprehensively discussed. This study thus provides a detailed methodology for the successful implementation of an ecosystem management framework on a county-scale based on the spatial partitioning of supply and demand.

AbstractResearch to date on urban ecosystem services has mainly been conducted in large cities, particularly in China, the USA and some European countries. This study examined the provision of urban ecosystem services in a Swedish municipality context, based on interviews with municipal stakeholders in strategic management and planning from six municipalities and a review of existing publications readily available to practitioners. The analysis focused on (1) the ecosystem services explicitly covered, (2) whether multifunctionality was covered and specific synergies and trade-offs identified and, (3) the spatial scale and context used for ecosystem services (valuation/mapping, planning, design or maintenance) in practical application. The results showed that regulatory services are very much the focus in municipal operations as well as in publications available to practitioners. This is reflected in the implementation of the concept through problem solving often related to regulatory services, using multifunctionality and win-win situations in ecosystem service supply. These findings contribute to the growing body of work exploring how the concept of ecosystem services is adapted and utilised in practice.
