This paper gives an overview of the value of ecosystem services of 10 main biomes expressed in monetary units. In total, over 320 publications were screened covering over 300 case study locations. Approximately 1350 value estimates were coded and stored in a searchable Ecosystem Service Value Database (ESVD). A selection of 665 value estimates was used for the analysis. Acknowledging the uncertainties and contextual nature of any valuation, the analysis shows that the total value of ecosystem services is considerable and ranges between 490 int$/year for the total bundle of ecosystem services that can potentially be provided by an ?average? hectare of open oceans to almost 350,000 int$/year for the potential services of an ?average? hectare of coral reefs. More importantly, our results show that most of this value is outside the market and best considered as non-tradable public benefits. The continued over-exploitation of ecosystems thus comes at the expense of the livelihood of the poor and future generations. Given that many of the positive externalities of ecosystems are lost or strongly reduced after land use conversion better accounting for the public goods and services provided by ecosystems is crucial to improve decision making and institutions for biodiversity conservation and sustainable ecosystem management.Peer reviewe

Many adaptation strategies focus on improving short‐term capacities to cope with environmental change, but ignore the possibility that they might inadvertently increase vulnerability to unforeseen changes in the future. To help develop more effective long‐term strategies, we present a conceptual framework of adaptation. The framework emphasizes that in order to ensure that existing problems are not exacerbated, adaptation must: (1) address both human‐induced and biophysical drivers of undesired ecological change; (2) maintain a diversity of future response options; and (3) nurture the kinds of human capacities that enable the uptake of those response options. These requirements are often not met when adaptation strategies rely on technological fixes, which tend to concentrate on coping with the biophysical symptoms of problems rather than addressing human behavioral causes. Furthermore, to develop effective, long‐term adaptation, greater emphasis is needed on strategies that enhance, rather than erode, the human values, skills, and behaviors conducive to sustainable activities. Participatory approaches to environmental stewardship are part of the solution to this problem.
