Because conventional markets value only certain goods or services in the ocean (e.g. fish), other services provided by coastal and marine ecosystems that are not priced, paid for, or stewarded tend to become degraded. In fact, the very capacity of an ecosystem to produce a valued good or service is often reduced because conventional markets value only certain goods and services, rather than the...
We live in a world of diminished ecological diversity. We extract energy, materials, and organisms from nature and modify landscapes at rates that cannot be sustained. These activities have resulted in accelerated rates of extinction, degradation, and loss of ecosystems, and disruption of the natural systems in which our cultures are embedded. The Society for Conservation Biology (SCB) believes...
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 ...
Crop pollination by bees and other animals is an ecosystem service of enormous economic value (Losey andVaughan 2006; Allsopp et al. 2008). Pollination can increase the yield, quality, and stability of crops as diverse as almond, cacao, canola, coffee, sunflower, tomato and watermelon. Indeed, Klein et al. (in press) found that 75% of globally important crops benefit from animal pollination. Th...
