This paper proposes a game theoretic modeling framework for the assessment of the trade-off between economic efficiency gains and biodiversity conservation in a fishery. It introduces a biodiversity index, and develops an application of the method couched on Namibian hake fisheries. Results from the illustrative example show that the opportunity...
This paper is drawn from a project report that was sponsored by the United Nations through the Benguela Current Large Marine Ecosystem Programme. We analyze the economics of fishery management in the Benguela Current Large Marine Ecosystem (BCLME), reviewing the case for and against regional co-operation in managing the BCLME....
Sea lice are natural parasites, and are spread between wild salmon stocks and farmed salmon. Studies indicate that sea lice from salmon farms not only cause economic losses to salmon aquaculture producers, but also affect other marine resources. Currently one of the most controversial debates over sea lice from salmon...
We describe the first effort at creating a global ex-vessel fish price database. We then demonstrate potential applications of the database by linking it to the Sea Around Us project's spatially defined catch database, which makes it possible to attach catch values to species both in time and space. There...
We argue in this paper that the present fishery policy goal of sustaining current levels of ecosystem resources will foreclose future options for the generation of food, wealth and services from ocean resources. Hence, only a policy of rebuilding of ecosystems can reverse this trend. A novel methodology, termed Back...
Some attempts have been made in the past to provide estimates of the value
of global fisheries. For example, catch values from marine fisheries have
been reported by the FAO (2008) and Sumaila et al. (2007). The World
Bank (2008) estimated that current economic rent from the worlds fisheries
is...
I will discuss the current state of IUU fishing in Africa as reported in the literature. I will discuss the scope of this illegal activity in the continent and the economic and socila loss to the continent due to IUU fishing.
The World Bank has constructed wealth accounts for nearly 15 years, most recently in The Changing Wealth of Nations. The accounts include produced capital, natural capital and human and social capital. Natural capital includes agricultural land, forests, subsoil assets and protected areas, but omit a number of critical natural capital...
Recent articles in the multidisciplinary fisheries literature have been critical
of fisheries economics concepts and literature. For example, a paper by
Bromley (2009) entitled Abdicating Responsibility: The Deceits of
Fisheries Policy: Fisheries 34(6):280-302, provides a critical review of
fisheries economics. I explore the main issues raised in this paper and...
