The economics of elephant management in Namibia.
Sutton, William Roy.

The economics of elephant management in Namibia. - 306 p.

Chairs: Lovell Jarvis; Douglas Larson.

Thesis (Ph.D.)--University of California, Davis, 2001.

The goal is to determine the effects of alternative management strategies on the economic welfare of Africans and on elephant populations. The African elephant is a species with substantial, multiple values. It also generates costs for the human populations that share its range. Elephant management has been a topic of international debate as elephant populations have declined during the past two decades. This dissertation develops a new model of renewable resources management that is capable of realistically representing the economic tradeoffs involved in elephant management. It shows that an increase in the price of ivory or a decrease in deterrent effectiveness can result in an increase in the optimal population size. The results are inconclusive due to a lack of information on the economics of interactions between elephants and farmers.

520 $a The goal is to determine the effects of alternative management strategies on the economic welfare of Africans and on elephant populations. The African elephant is a species with substantial, multiple values. It also generates costs for the human populations that share its range. Elephant management has been a topic of international debate as elephant populations have declined during the past two decades. This dissertation develops a new model of renewable resources management that is capable of realistically representing the economic tradeoffs involved in elephant management. It shows that an increase in the price of ivory or a decrease in deterrent effectiveness can result in an increase in the optimal population size. The results are inconclusive due to a lack of information on the economics of interactions between elephants and farmers.
520 $a A comprehensive typology of the costs of living with elephants is developed. A survey is implemented to measure the costs and benefits to local households of living with elephants in the Caprivi Region of Namibia. A new and economically rigorous approach to measuring the costs is developed using willingness to pay. A bivariate probit model is derived that simultaneously estimates WTP money, WTP maize, and the shadow value of maize in an internally consistent manner.
520 $a Results are that wildlife imposes significant costs on farm households, but less than expected. Elephants generate fewer costs than other wildlife. Other wild herbivores generate higher costs as a group, and predators on a per-incident basis. Livestock attacks cost farmers more than all wildlife combined. There is a fundamental resource allocation problem: too many livestock and too few crops.
520 $a Barbed wire fencing of fields is an economically efficient method to deter livestock; electric fencing is not economically efficient for deterring wildlife. Costs incurred from wildlife attacks are due to human as well as animal behavior; they are higher in areas of high agricultural productivity than in areas of high wildlife density. On the margin, farmer welfare would be enhanced most by reducing predator attacks. In aggregate, efforts should concentrate on reducing livestock numbers, enhancing property rights regarding grazing and livestock damage, and preventing livestock attacks.
