This paper presents an analysis of Non-Timber Forest Product (NTFP) collection and
income in the Eastern Arc Mountains (EAM) in Tanzania, using data of the Tanzanian
National Household Budget Survey 2007. The results are compared with the analysis
presented in Schaafsma et al. (2011), which is based on a pooled dataset of 7 different
local surveys. For both datasets, a household production function of NTFP collection is
estimated, and then transferred and aggregated across the EAM to estimate the
economic value of the annual flow of NTFP benefits. Although both analyses suffer from
data limitations related to the employed survey methods and valuation inaccuracies
related to inexistent markets, the resulting value estimates are of a comparable order of
magnitude and are also comparable to earlier NTFP valuation studies. This result is
important for the validation of the results presented in Schaafsma et al. (2011) and their
use in future cost-benefits analyses.
