The objective of the study was to map sweet potato value chain linkages between actors, processes and activities in Tanzania. The study is cross sectional in design.The study was conducted in Shinyanga rural and Mwanza urban districts. The study used individual interviews, focused group discussions; review of relevant practical documents and discussions with key informants. A total of 150 actors in the value chain participated. Data collected was summarized using Statistical Package of Social Science (SPSS) and content analysis. Analysis of data shows that "Michembe" and "Matobolwa" were two main local made value added products derived from sweet potatoes preferred by producers. In general sweet potatoes production is marked with low production and productivity. Low productivity is a result of poor agronomic practices and low level of production technology application among others. Three main marketing channels exist in the study area: Producers selling directly to consumer; producers to retailers to consumer; and producers to hawkers/village vendors to consumer. Moreover data revealed that (50.7%) of sampled producers set prices after hearing from their fellow farmers. About (44%) of the sampled producers sell their produce direct to the market. The sub sector in general faces a number of structural and technological problems that need immediate attention to revamp agricultural sector development.

This paper analyzes the impacts of indirect tax benefits policy reforms on income distribution and poverty in Tanzania by applying a standard static microsimulation model TAZMOD v1.8. The simulations model two indirect tax reforms involving changes to the excise duty and value-added tax rates on alcoholic beverages and tobacco products, and changes to employers' and employees' contributions to the National Health Insurance Fund. The results of the first reform find a positive effect on government tax revenue and a neutral effect on income distribution and poverty. The results of the second reform find a positive effect on household income distribution and consumption. The findings show that, despite increasing unequal income distribution, poverty indicators fell.
