Conventional bioeconomic analyses focus on the economically optimal exploitation of the fish resources by maximizing the resource rent subject to a resource restriction. This paper expands this type of analysis by addressing the fishing activity's impact on the ecosystem biologically as well as economically. A dynamic bioeconomic model is used...
Generic Quality Assurance Schemes referred to as Schemes, have been established in the primary industries in many countries. They represent an important part of the generic marketing for different categories of foodstuffs, especially primary produce. Such Schemes are established due to, among other things, severe competition in the international food...
Forest managers are challenged to restore resilience to forests with an elevated risk of stand-replacing fire by using mechanical thinning and prescribed fire. Implementation of these methods can be constrained by mandates to conserve sensitive wildlife species like the Pacific marten (Martes caurina). Martens avoid simplified forest stands created by...
Explosively erupting volcanoes and megathrust earthquakes (Mw 8+ magnitude) occur at subduction zones and adjacent volcanic arcs. Volcanic eruptions are observed occurring close in time to megathrust earthquakes in the historical record from at least the 18th century CE to present in locations globally, including Japan in 1707 CE (Chesley...
This paper analyses the management of the Atlantic salmon stocks in the Baltic Sea through a coalition game in partition function form. The signs of economic and biological overexploitation of these salmon stocks over the last two decades indicate that cooperation among the harvesting countries, under the European Union's Common...
The ~1 Myr history of the Purico-Chascon volcanic complex (PCVC) records significant changes in the production and storage of magmas in the crust. At ~1 Ma activity at the PCVC initiated with the eruption of a large 80-100 km³ crystal-rich dacite ignimbrite with restricted whole rock ⁸⁷Sr/⁸⁶Sr isotope ratios between...
