Cost-benefit analysis:
Economic internal rate of return over 16 years
14.91%
Economic net present value over 16 years @ 8% discount rate
7,795,340
Notes: a In 2005 US$1.00 was equal to N$6.67 (Namibia Dollars); inflation factor to 2007 is 1.11.
b Donor and government spending specifically on CBNRM programme.
c Total direct and indirect contribution to net national income, attributable to CBNRM activities, including
impact through the value added multiplier, plus appreciation of game stocks in CBNRM areas
Sources: Unpublished Data, 2007, Ministry of Environment and Tourism; NACSO, 2006
included investments in wildlife damage mitigation. More recent work on the
costs of wildlife damage in the CBNRM context in Namibia's north-east (Jones
and Barnes, 2007) indicates that the benefits of CBNRM tourism at community
level can outweigh the costs of damage borne by households. The economic
analyses, above, do not include the opportunity costs of land, but as pointed out
by Barnes et al (2002) the opportunity costs of land in the arid and semi-arid
lands of Namibia are low. Barnes et al (2001) analysed alternative land uses in
semi-arid northern Botswana and confirmed this.
Conclusion
The findings described above help us to answer the key policy questions about
CBNRM posed in the introduction.
