Humans and the ecosystem services they depend on are threatened by climate change. Places with high or growing human population as well as increasing climate variability, have a reduced ability to provide ecosystem services just as the need for these services is most critical. A spiral of vulnerability and ecosystem degradation often ensues in such places. We apply different global conservation...
Effective ecosystem risk assessment relies on a conceptual understanding of ecosystem dynamics and the synthesis of multiple lines of evidence. Risk assessment protocols and ecosystem models integrate limited observational data with threat scenarios, making them valuable tools for monitoring ecosystem status and diagnosing key mechanisms of decline to be addressed by management. We applied the ...
Human health often depends on environmental variables and is generally subject to widespread and comprehensive surveillance. Compared with other available measures of ecosystem health, human disease incidence may be one of the most useful and practical bioindicators for the often elusive gauge of ecologic well-being. We argue that many subtle ecosystem disruptions are often identified only as a...
Smail, Robert A.; Lewis, David J. 2009. Forest-land conversion, ecosystem services, and economic issues for policy: a review. PNW-GTR-797. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 40 p. The continued conversion and development of forest land pose a serious threat to the ecosystem services derived from forested landscapes. We argue that de...
The natural world generates a range of valuable goods and services that support human well–being. !ese goods and services, collectively called ecosystem services, are typically provided free of charge and often have characteristics of public goods. Like other public goods, ecosystem services will not be provided optimally by aggregating the decisions of individuals motivated by self–interest. F...
449 Gross revenues from marine capture fisheries worldwide are estimated at between US$80 billion and 85 billion annually1–3. As a primary industry4, fisheries support the wellbeing of nations through direct employment in fishing, processing and ancillary services amounting to between US$220 billion and 235 billion annually in 2003 (ref. 5). Globally, fish provide nearly three billion people wi...
The millions of species on our planet, including humans, interact with one another in many ways. These interactions among and between species are what define ecosystems. Ecosystems, in turn, provide many environmental benefits or “services” that support human life and well-being. Ecosystem services are the transformation of a set of natural resources (for example, plants and animals, air and wa...
Humanity faces a major global challenge in achieving wellbeing for all, while simultaneously ensuring that the biophysical processes and ecosystem services that underpin wellbeing are exploited within scientifically informed boundaries of sustainability. We propose a framework for defining the safe and just operating space for humanity that integrates social wellbeing into the original planetar...
Modern public health challenges require interdisciplinary solutions that integrate knowledge of human behavior and its complex relationship with the physical environment. Historically, this discourse was dominated by studies of hazards and other negative health consequences associated with human–environment interactions. However, growing evidence suggests that contact with green spaces (e.g., p...
Biodiversity and many ecosystem services provide a key instrumental and constitutive factor determining human wellbeing [1]. Pollination is among a valuable ecosystem services which provides a variety of benefits including food and fiber, plantderived medicines, ornamentals, aesthetics, genetic diversity, and overall ecosystem resilience [1,2]. About 2/3rd of the crop plants that feed the world...
