| There is a growing interest in assessing ecosystem services to improve ecosystem management in landscapes containing a mix of different ecosystems. While methodologies for assessing ecosystem services are constantly improving, only little attention has been given to the identification of which ecosystem services to assess. Service selection is mostly based on current state of the landscape although many landscapes are both inherently complex and rapidly changing. In this study we examine whether scenario development, a tool for dealing with uncertainties and complexities of the future, gives important insights into the selection of ecosystem services in changing landscapes. Using an agricultural landscape in South Africa we compared different sets of... |

| The study reviews, based on the state-of-the-art findings, some uncertainties associated with wave data and models currently used in design and operation procedures of ship and offshore structures. Although the same basic principles prevail for hydrodynamic loads on ships and offshore structures, actual problems and methods for assessing these loads in the design and operation stage are not the same. Different wave data and models are used for specifying design and operational criteria for these two types of platforms and different uncertainties are related to them. Wave data and models used to define sea state characteristics are discussed and particular attention is given to the associated sources of uncertainties. Some weaknesses of wave input used in... |

| We give empirical welfare results for global greenhouse gas emission control, using the first multiparty model to combine tax-versus-trading under uncertainties with revenue recycling. Including multiple parties greatly reduces the welfare advantage of an emissions tax over emissions (permit) trading in handling abatement-cost uncertainties, from that shown by existing, single-party literature. But a tax has a different, much bigger advantage, from better handling uncertainties in business-as-usual emissions. Either mechanism's free emissions share, from tax thresholds or free permits, which lowers its possible welfare gain from revenue recycling, may however dominate any tax-versus-trading advantage. Moreover, political and practical constraints, such as... |
