Robinson, Elizabeth J Z and Razack Lokina. 2009. “Spatial Aspects of Forest Management and Non-Timber Forest Product Extraction in Tanzania .” EfD Discussion Paper 09.
The authors explore the impact of participatory forest management (PFM) in Tanzania that excludes villagers from traditional access to forests to collect non-timber forest products (NTFPs).
Using fieldwork and a spatial-temporal model, they focused on forest degradation and regeneration and villagers’ utility before and after PFM has been introduced. Although the PFM forest improves, they found that a moratorium on NTFP collection often adversely affects villagers’ livelihoods and more distant, less-protected forests.
