Conservation of wildlife. A bio-economic model of a wildlife reserve under the pressure of habitat destruction and harvesting outside the reserve
(Working paper; Arbeidsnotat, 2003-09)
Biodiversity is today threatened by many factors of which destruction and reduction of habitats are considered most important for terrestrial species. One way to counteract these threats is to establish reserves with restrictions on land-use and exploitation. However, very few reserves can be considered islands, wildlife species roam over large expanses, often via some density dependent dispersal ...
Marine reserves. A bio-economic model with asymmetric density dependent migration
(Working paper; Arbeidsnotat, 2004-10)
A static bioeconomic model of a marine reserve is introduced, allowing asymmetric density dependent migration between the reserve and the fishable area. This allows for habitat or ecosystem differences within and outside a reserve not described in earlier studies. Four scenarios are studied; a) maximum harvest, b) maximum current profit, c) open access and d) maximum sustainable yield (MSY) in ...
On the economics of ecological nuisance
(Working paper; Arbeidsnotat, 2005-03)
This paper analyses the economics of pest and nuisance relating to wild animals. It studies stylised models where wild animals represent a direct nuisance to agricultural production through grazing and crop damage. Such damage is particularly relevant in poor rural communities, where people are dependent on livestock and crop production and at the same time are living close to nature and wildlife. ...
