This paper reviews recent work examining two topics of economic research vital for invasive species policy—integration and valuation. Integration requires bioeconomic models that blend invasive biology with economic circumstances and the feedback loops between the two systems. Valuation requires nonmarket valuation associated with human and environmental damages posed by invasive species. We ar...

The high price of flying fish eggs in Japan encourages South Sulawesi fishermen in Indonesia to harvest increasing quantities of eggs every year. Similarly, the increasing local demand for flying fish encourages Indonesian fishermen to use gill nets to catch more fish. As a consequence of this increasing quantity of eggs harvested and fish caught, Indonesia has become concerned about the overex...

Water is a finite resource that must be shared among multiple users and economic and conservation objectives can often be seen as being in conflict. We explored this perception by conducting an integrated bioeconomic analysis of irrigated agriculture and the conservation of freshwater attributes in an agricultural landscape, the Tasmanian Midlands. We constructed a simple bioeconomic model base...

Bioeconomic models make it possible to assess ex-ante the consequences of public interventions in agriculture sector. Yet since policymakers rarely participate their design or use, these are often too complex do not address questions. This article describes implementation a nine-step participatory modelling process involving regional policymakers, and analyses contribution this cross-brainstorm...

Understanding ecological complexity has stymied scientists for decades. Recent elucidation of the famously coined "devious strategies for stability in enduring natural systems" has opened up a new field of computational analyses of complex ecological networks where the nonlinear dynamics of many interacting species can be more realistically mod eled and understood. Here, we describe the first e...

1 Fishing down the value chain: modelling the impact of biodiversity loss in freshwater fisheries-the case of Malawi. Abstract This paper considers the importance of the level of diversity in freshwater fisheries. An aggregated Gordon-Schaefer model, modified to include both environmental and bioeconomic diversity variables, is fitted to data from a gillnet fishery in Lake Malawi. Pressure on s...

Marine reserves are an effective tool for protecting biodiversity locally, with potential economic benefits including enhancement of local fisheries, increased tourism, and maintenance of ecosystem services. However, fishing communities often fear short-term income losses associated with closures, and thus may oppose marine reserves. Here we review empirical data and develop bioeconomic models ...

We analyze the problem of an integrated management of fisheries by using fish farming as a tool for restocking fish populations depleted by overfishing pressure. We first use a simple heuristic dynamic model, taken from a classical example of mathematical bioeconomics, in order to prove that fish restocking may be an efficient tool for sustainable fishery management in situations where excessiv...
