The paper analyses economic and ecological mechanisms determining wildlife investments in the context of pastoral exploitation of the semi-arid African rangeland. We consider a group of pastoralists practising two production activities, cattle herding and wildlife harvesting. Livestock and...

We study the economy and ecology of sheep farming under future climate change scenarios. The analysis is at the farm level and includes two different categories of the animals, ewes (adult females) and lambs with a crucial distinction between the outdoor grazing season and the winter indoor...

During the last few decades wildlife trophy hunting has increasingly replaced traditional meat hunting. The economics of trophy hunting is analyzed with the Scandinavian moose (Alces alces) serving as an example. A four-stage model (calf, yearlings, adult female and adult male) is formulated....

A cost-benefit analysis of moose (Alces alces) harvesting in Scandinavia is presented within the framework of an age structured model with four categories of animals (calves, yearlings, adult females, and adult males). The paper aims to demonstrate the economic content of such a wildlife model...
