Abstract
This chapter is based on the findings of a study that was conducted in 12 tourist
hunting blocks (HBs) in Tanzania. The aim of the study was to evaluate the total
economic values (TEV) of the HBs to inform the decision of auctioning to
potential hunting companies and sustainable utilization and conservation of the
blocks. For each of the 12 HBs, the study estimated the TEV and its five
individual components namely; the direct use values (DUV), indirect use values
(IUV), option/quasi-option values (OV), existence values, as well as, the bequest
values (BV). The values were estimated using the Analytic Multicriteria Valuation
Method (AMUVAM). The TEV and its components were estimated using a time
horizon of 10 years (the mean tenure for a winning hunting company). The
results show that the average TEV of HBs was USD 93,981,422 with the
minimum and maximum TEV amounting to USD 6,215,588 to USD 653,470,695
per hunting block respectively. Of the five components of TEV, the bequest
values (BV) constituted the largest proportion (about 50% of TEV), followed by
the existence values (EV) (19%), option/quasi-option values (OV) (12%), and
indirect use values (IUV) (10%). The direct use values or DUV (i.e. the values of
hunting and photographic tourism) constituted only 1% of TEV. The EV of HBs
ranged from USD 632,210 to the maximum of USD 125,147,285 and the average
was USD 17,625,305. The cultural heritage values (CHV) constituted the largest
component of EV (about 50%), followed by the aesthetic enjoyment values (AEV)
(27%), and biodiversity conservation values (BDV) (23%). The study emphasises
the importance of using a thorough understanding of human values to inform
decisions about how to devote ecosystems, like HBs, to both direct and indirect purposes. We also advocate enhancing the skills of the personnel responsible for
managing and allocating the use of these ecosystems so they can conduct
economic assessments of ecosystems using both basic and sophisticated
analytical tools, such as geographic information systems (GIS), relational
databases, and globally accessible websites-based tools like InVEST (Integrated
Valuation of Environmental Services and Tradeoffs), ARIES (Artificial Intelligence
for Ecosystem Services), and Costing Nature.
