دانلود کتاب The Economic Value of Elephants

ELEPHANTS PLAY a huge role within any landscape where they occur. They are habitat engineers. As charismatic species they awaken emotions among people like few others. As keystone species, they contribute significantly to the integrity of ecosystems and must be very carefully managed. From an economic perspective, they are also value generators. In this broad context, we first consider the range of relevant economic values, using the Total Economic Value approach in a generic sense, and then apply this framework to identify the specific factors that determine the economic value of elephants in South Africa. Thereafter we summarise both regional (southern African) and international studies that consider the economic value of elephants. We conclude with an assessment of the state of knowledge on elephants’ contribution to the economic value of elephant-containing ecosystems and the economy as a whole.
This assessment borrows heavily from studies concerning the economic value of elephants carried out in Botswana, Namibia, and Zimbabwe, since similar studies in South Africa could not be located. To date, published studies in South Africa focused either on the cost of the individual elephant management options – which is a subject treated in the relevant management chapters of this book – or else investigations of the value of tourism. The specific contribution of elephants to the value of tourism was not isolated in these studies.
