As part of the ecosystem approach to managing fisheries and other uses of marine ecosystems, there has been a growing call for the development of integrated assessment tools to support the provision of both tactical and strategic management advice. Of particular importance in this domain is the development of models...
This report is an economic and policy assessment of the biological effectiveness and economic efficiency of incentive mechanisms for private landowners to conserve U.S. biodiversity. Its focus is on rural lands that tend to be used for forestry, agriculture and residential purposes.
Ideally, we seek to develop perfectly integrated ecological-economic models, drawing on the best data, modeling and knowledge of each of the disciplines, into one coherent model to inform policy. The realities of achieving such are thwarted by data and model compatibility issues. For example, ecological data may be available on...
This study compares globally available integrated ecological-economic models with focus on use and implementation in scientific and advisory contexts. The Ecosystem based Approach to (Fisheries) Management (EAM) calls for an understanding and management of fisheries and other uses of the marine environment that explicitly take into account ecological, economic and...
Biologists have criticized traditional biomass models in fishery economics for being oversimplified. Biological stock assessment models are more sophisticated with regard to biological content, but rarely account for economic objectives. Recently, age-structured models of fish stocks have increasingly been used in fisheries economics, but applications have so far mainly been...
The paper is the first attempt to explore the ecological and economic impacts of genetic interaction between farmed and wild salmon over generations. An age- and stage-structured bioeconomic model is developed. The biological part of the model includes age-specific life history traits such as survival rate, fecundity, spawning success for...
This paper deals with the sustainable management of a renewable resource
based on individual and transferable quotas (ITQs) when agents differ in terms of
harvesting costs or catchability. In a dynamic bio-economic model, we determine
the conditions under which the manager of an ITQ system can achieve sustainability
objectives which...
Economic analysis of optimal ecosystem management in the presence
of a threshold has typically ignored the potential for induced behavioral responses. This
paper contributes to the literature on non-convex ecosystem management by considering
the implications of a particular behavioral response in a regional economy - that of amenity-led
growth -...
To achieve sustainable fisheries, ecosystem-based fisheries management
yields increasing attention. However, so far mainly single-species models
are used to develop management advice, not accounting for species
interaction. In particular many traditional fisheries economic models have
been criticized by biologists, especially if results were gained by rather
simple biomass models. Therefore,...
The rapid pace of climate change and increased human disturbance of ecosystems in the Arctic is bringing urgency to concern over non-native species introductions and their potential threats to the marine environment and its economic productivity, where before environmental conditions served as a barrier to their establishment. The same characteristics...
