A good illustration of the discrepancy between current estimates of importance comes from comparing the value for woodfuel reported for Africa (most woodfuel is harvested from naturallyregenerating rather than planted sources in the continent) in the 2010 GFRA (1.4 billion USD annually) with the World Bank’s (2011) much higher estimate of the value of the charcoal industry in the sub-Sahara region (eight billion USD annually). Several reasons have been highlighted as to why it is difficult to adequately represent NTFP value, including the multiplicity of products, informal trade and bartering that occurs in unmonitored local markets, direct household provisioning without products entering markets at all, and the fact that wild-harvested resources are excluded from many large-scale rural household surveys
