Biodiversity Conservation in a Game Theoretic Model of the Fishery

By Ussif Rashid Sumaila

ABSTRACT

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 shows that the opportunity cost of achieving a "near perfect" level of biodiversity conservation is high. On a more positive note, however, the results indicate that it is possible (through appropriate management action) to achieve very high biodiversity levels without losing most of the potential economic gains.
