Accounting for ecosystem services as a way to understand the requirements for sustainable development.

Millennium Ecosystem Assessment documented the importance of ecosystem services. It is therefore important that these services are included in our economic accounts (Standard National Accounts), as long as we believe that these accounts should tell us something about our wellbeing. This requires measures of the ecosystem assets and their accounting prices. This article discusses how the concept of inclusive wealth can be exploited for creating such accounts.

Coping with uncertainty: a call for a new science-policy forum.

The scientific and policy worlds have different goals, which can lead to different standards for what constitutes "proof" of a change or phenomena, and different approaches for characterizing and conveying uncertainty and risk. These differences can compromise effective communication among scientists, policymakers, and the public, and constrain the types of socially compelling questions scientists are willing to address. In this paper, we review a set of approaches for dealing with uncertainty, and illustrate some of the errors that arise when science and policy fail to coordinate correctly. We offer a set of recommendations, including restructuring of science curricula and establishment of science-policy forums populated by leaders in both arenas, and specifically constituted to address problems of uncertainty.
