Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to
marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice they are not a
panacea and distribution and equity issues have been raised in many cases. To overcome those issues,
ITQ systems...
Nuclear waste is going nowhere, and neither is the debate over its disposal. The problem, growing every day, has proven intractable, with policymakers on one side, armed with daunting technical data, and the public on the other, declaring: not in my backyard. This timely volume offers a look past our...
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...
Early-successional stages have been truncated and altered in many western U.S. forest landscapes by
planting conifers, controlling competing vegetation, suppressing fire, and focusing on maintaining late-seral
species and undisturbed riparian zones. Declining area of early-successional stages may be reducing
resilience and sustainability on landscapes that experience elevated disturbance related to...

Premise of research. The lianoid habit is found in 125 extant plant families and is most diverse and abundant in structurally complex forests, such as tropical forests. A stem with lianoid anatomy is described from Cretaceous sediments of Hornby Island, British Columbia.
Methodology. The stem segment, 2.5 cm in diameter...
Management changes in the coral reef fin fish fishery of the Great Barrier
Reef provide a natural experiment of the efficacy of combining no-take
areas and dedicated catch shares. A spatially-explicit bio-economic model
of the fishery is used to analyze the tradeoffs between biomass and the net
returns from fishing...
