Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem.We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon...

The year 2020 is a critical year for sustainable development policy and practice with the review and renewal of various international commitments including the Sustainable Development Goals, the Convention on Biological Diversity and the Paris Agreement. The post-2020 agenda needs to be informed...

This paper describes how Natural Capital Accounting (NCA) can be integrated into economy wide analytical frameworks to enhance evidence based decision making. Examples from applications of the Integrated Environmental Economic Modelling (IEEM) Platform show how explicitly accounting for the...

In a democratic system, policy makers have to take the preferences of the citizens into account. Since we live in a world with scarce resources, one is asked to make choices regarding the use and management of these resources. In this context, if policy makers decide to invest in the protection...

Artisanal fishery in the Venice lagoon is a multi-target activity with a long tradition. It was the main fishing activity till the late '80s when, after the introduction and spread of the Manila clam (Tapes philippinarum), the mechanical clam harvesting started. A mass-balance model of the...

This paper presents the first rigorous empirical evidence of the impact of a large hydrocarbon project in both its economic and environmental dimension. Concentrating on Peru’s largest hydrocarbon project, the Camisea Gas Project, which began operating in the dense Amazonian jungle under...

Safeguarding the future of Venice is a globally recognised challenge of urban sustainability. We propose a sustainable management model, alternative to the current strategy, that primarily focuses on the built heritage and which interprets the city together with its encircling lagoon as a matrix...

We study the effectiveness of climate change policy in a model with multiple non-renewable resources that differ in their carbon content. We find that, when allowing some time between announcement and implementation of a cap on carbon dioxide emissions, emissions from non-renewable energy...

In this paper stochastic dynamic programming is used to investigate land conversion decisions taken by a multitude of landholders under uncertainty about the value of environmental services and irreversible development. We study land conversion under competition on the market for agricultural...

Policies aimed at reducing emissions from fossil fuels may increase climate damages. This "Green Paradox" emerges if resource owners increase near-term extraction in fear of stricter future policy measures. Hans-Werner Sinn (2008) showed that the paradox occurs when increasing resource taxes are...
